They conform with the highest standard for color contrast between any given combination of background and foreground values. This corresponds to the WCAG AAA standard, which specifies a minimum rate of distance in relative luminance of 7:1. Modus Operandi (‘modus-operandi’) is a light theme, while Modus Vivendi (‘modus-vivendi’) is dark. Each theme’s color palette is designed to meet the needs of the numerous interfaces that are possible in the Emacs computing environment. The overarching objective of this project is to always offer accessible color combinations. There shall never be a compromise on this principle. If there arises an inescapable trade-off between readability and stylistic considerations, we will always opt for the former. To ensure that users have a consistently accessible experience, the themes strive to achieve as close to full face coverage as possible (see *note Face coverage::). Starting with version 0.12.0 and onwards, the themes are built into GNU Emacs (current version is 0.13.0). * Menu: * How do the themes look like:: * Learn about the latest changes:: File: modus-themes.info, Node: How do the themes look like, Next: Learn about the latest changes, Up: Overview 1.1 How do the themes look like =============================== Check the web page with the screen shots (https://protesilaos.com/modus-themes-pictures/). There are lots of scenarios on display that draw attention to details and important aspects in the design of the themes. They also showcase the numerous customization options. *note Customization options: Customization Options. File: modus-themes.info, Node: Learn about the latest changes, Prev: How do the themes look like, Up: Overview 1.2 Learn about the latest changes ================================== Please refer to the web page with the change log (https://protesilaos.com/modus-themes-changelog). It is comprehensive and covers everything that goes into every tagged release of the themes. File: modus-themes.info, Node: Installation, Next: Enable and load, Prev: Overview, Up: Top 2 Installation ************** The Modus themes are distributed with Emacs starting with version 28.1. On older versions of Emacs, they can be installed using Emacs’ package manager or manually from their code repository. Modus Operandi (light theme) and Modus Vivendi (dark) are normally distributed as standalone packages in Emacs-specific archives. There also exist packages for GNU/Linux distributions. * Menu: * Install from the archives:: * Install on GNU/Linux:: File: modus-themes.info, Node: Install from the archives, Next: Install on GNU/Linux, Up: Installation 2.1 Install from the archives ============================= ‘modus-operandi-theme’ and ‘modus-vivendi-theme’ are available from GNU the ELPA archive, which is configured by default. Prior to querying any package archive, make sure to have updated the index, with ‘M-x package-refresh-contents’. Then all you need to do is type ‘M-x package-install’ and specify the theme of your choice. File: modus-themes.info, Node: Install on GNU/Linux, Prev: Install from the archives, Up: Installation 2.2 Install on GNU/Linux ======================== The themes are also available from the archives of some GNU/Linux distributions. These should correspond to a tagged release rather than building directly from the latest Git commit. It all depends on the distro’s packaging policies. * Menu: * Debian 11 Bullseye:: * GNU Guix:: File: modus-themes.info, Node: Debian 11 Bullseye, Next: GNU Guix, Up: Install on GNU/Linux 2.2.1 Debian 11 Bullseye ------------------------ The two themes are distributed as a single package for Debian and its derivatives. Currently in the unstable and testing suites and should be available in time for Debian 11 Bullseye (next stable). Get them with: sudo apt install elpa-modus-themes File: modus-themes.info, Node: GNU Guix, Prev: Debian 11 Bullseye, Up: Install on GNU/Linux 2.2.2 GNU Guix -------------- Users of either the Guix System (the distro) or just Guix (the package manager) can get each theme as a standalone package. guix package -i emacs-modus-operandi-theme And/or: guix package -i emacs-modus-vivendi-theme File: modus-themes.info, Node: Enable and load, Next: Customization Options, Prev: Installation, Up: Top 3 Enable and load ***************** This section documents how to load the theme of your choice and how to further control its initialization. It also includes some sample code snippets that could help you in the task, especially if you intend to use both Modus Operandi and Modus Vivendi. * Menu: * Load automatically:: * Load at a given time or at sunset/sunrise:: * Toggle between the themes on demand:: * Configure options prior to loading:: File: modus-themes.info, Node: Load automatically, Next: Load at a given time or at sunset/sunrise, Up: Enable and load 3.1 Load automatically ====================== A simple way to load the theme from your Emacs initialization file is to include either of the following expressions: (load-theme 'modus-operandi t) ; Light theme (load-theme 'modus-vivendi t) ; Dark theme Make sure to remove any other theme that is being loaded, otherwise you might run into unexpected issues. Note that you can always ‘M-x disable-theme’ and specify an item. The command does exactly what its name suggests. To deactivate all enabled themes at once, in case you have multiple of them enabled, you may evaluate the expression: (mapc #'disable-theme custom-enabled-themes) File: modus-themes.info, Node: Load at a given time or at sunset/sunrise, Next: Toggle between the themes on demand, Prev: Load automatically, Up: Enable and load 3.2 Load at a given time or at sunset/sunrise ============================================= It is possible to schedule a time during the day at or after which a given theme will be loaded.(1) ;; Light for the day (load-theme 'modus-operandi t t) (run-at-time "05:00" (* 60 60 24) (lambda () (enable-theme 'modus-operandi))) ;; Dark for the night (load-theme 'modus-vivendi t t) (run-at-time "21:00" (* 60 60 24) (lambda () (enable-theme 'modus-vivendi))) A modified version of the above technique is to use the sunrise and sunset as references, instead of specifying a fixed hour value.(2) If you set ‘calendar-latitude’ and ‘calendar-longitude’ (defined in the built-in ‘solar.el’ library—read it with ‘M-x find-library’), you can automatically switch between both themes at the appropriate time-of-day. Note that _those calendar variables need to be set before loading the themes_. ;; Define coordinates (setq calendar-latitude 35.17 calendar-longitude 33.36) ;; Light at sunrise (load-theme 'modus-operandi t t) (run-at-time (nth 1 (split-string (sunrise-sunset))) (* 60 60 24) (lambda () (enable-theme 'modus-operandi))) ;; Dark at sunset (load-theme 'modus-vivendi t t) (run-at-time (nth 4 (split-string (sunrise-sunset))) (* 60 60 24) (lambda () (enable-theme 'modus-vivendi))) For the sake of completeness, the ‘load-theme’ call in these snippets is slightly different than the one shown in *note Load automatically::, because it does not enable the theme directly: the subsequent ‘enable-theme’ does that when needed. ---------- Footnotes ---------- (1) Contributed on Reddit by user ‘b3n’, <https://www.reddit.com/r/emacs/comments/gdtqov/weekly_tipstricketc_thread/fq9186h/>.

File: modus-themes.info, Node: Toggle between the themes on demand, Next: Configure options prior to loading, Prev: Load at a given time or at sunset/sunrise, Up: Enable and load 3.3 Toggle between the themes on demand ======================================= With both themes available, it is possible to design a simple command to switch between them on demand. (defun modus-themes-toggle () "Toggle between `modus-operandi' and `modus-vivendi' themes." (interactive) (if (eq (car custom-enabled-themes) 'modus-operandi) (progn (disable-theme 'modus-operandi) (load-theme 'modus-vivendi t)) (disable-theme 'modus-vivendi) (load-theme 'modus-operandi t))) You could use ‘(mapc #'disable-theme custom-enabled-themes)’ instead of disabling a single target, but you get the idea. File: modus-themes.info, Node: Configure options prior to loading, Prev: Toggle between the themes on demand, Up: Enable and load 3.4 Configure options prior to loading ====================================== If you plan to use both themes and wish to apply styles consistently (see *note Customization Options::), you could define wrapper functions around the standard ‘load-theme’ command. These extend the simple function we presented in *note Toggle between the themes on demand::. Here is a comprehensive setup (the values assigned to the variables are just for the sake of this demonstration):(1) (defmacro modus-themes-format-sexp (sexp &rest objects) `(eval (read (format ,(format "%S" sexp) ,@objects)))) (dolist (theme '("operandi" "vivendi")) (modus-themes-format-sexp (defun modus-%1$s-theme-load () (setq modus-%1$s-theme-slanted-constructs t modus-%1$s-theme-bold-constructs t modus-%1$s-theme-fringes 'subtle ; {nil,'subtle,'intense} modus-%1$s-theme-mode-line '3d ; {nil,'3d,'moody} modus-%1$s-theme-faint-syntax nil modus-%1$s-theme-intense-hl-line nil modus-%1$s-theme-intense-paren-match nil modus-%1$s-theme-links 'faint ; {nil,'faint,'neutral-underline,'faint-neutral-underline,'no-underline} modus-%1$s-theme-comments 'green ; {nil,'green,'yellow} modus-%1$s-theme-no-mixed-fonts nil modus-%1$s-theme-prompts nil ; {nil,'subtle,'intense} modus-%1$s-theme-completions 'moderate ; {nil,'moderate,'opinionated} modus-%1$s-theme-diffs nil ; {nil,'desaturated,'fg-only} modus-%1$s-theme-org-blocks 'grayscale ; {nil,'grayscale,'rainbow} modus-%1$s-theme-headings ; Read further below in the manual for this one '((1 . section) (2 . line) (t . rainbow-line-no-bold)) modus-%1$s-theme-variable-pitch-headings nil modus-%1$s-theme-scale-headings t modus-%1$s-theme-scale-1 1.1 modus-%1$s-theme-scale-2 1.15 modus-%1$s-theme-scale-3 1.21 modus-%1$s-theme-scale-4 1.27 modus-%1$s-theme-scale-5 1.33) (load-theme 'modus-%1$s t)) theme)) (defun modus-themes-toggle () "Toggle between `modus-operandi' and `modus-vivendi' themes."

File: modus-themes.info, Node: Customization Options, Next: Advanced customization (do-it-yourself), Prev: Enable and load, Up: Top 4 Customization Options *********************** The Modus themes are highly configurable, though they should work well without any further tweaks. By default, all customization options are set to ‘nil’. All customization options need to be evaluated before loading their theme (see *note Enable and load::). * Menu: * Bold constructs:: Toggle bold constructs in code * Slanted constructs:: Toggle slanted constructs (italics) in code * Syntax highlighting:: Toggle subtle coloration in programming modes * No mixed fonts:: Toggle mixing of font families * Link underline:: Toggle underlined text in links (deprecated for 0.14.0) * Link styles:: Choose color intensity or no underline for links * Comment styles:: Choose accent color for comment lines * Command prompts:: Choose among plain, subtle, or intense prompts * Mode line:: Choose among plain, three-dimension, or moody-compliant styles * Completion UIs:: Choose among standard, moderate, or opinionated looks * Fringes:: Choose among plain, subtle, or intense fringe visibility * Line highlighting:: Toggle intense style for current line highlighting * Matching parentheses:: Toggle intense style for matching delimiters/parentheses * Diffs:: Choose among intense, desaturated, or text-only diffs * Org mode blocks:: Choose among plain, grayscale, or rainbow styles * Heading styles:: Choose among several styles, also per heading level * Scaled headings:: Toggle scaling of headings * Headings' font:: Toggle proportionately spaced fonts in headings File: modus-themes.info, Node: Bold constructs, Next: Slanted constructs, Up: Customization Options 4.1 Option for more bold constructs =================================== Symbol names: • ‘modus-operandi-theme-bold-constructs’ • ‘modus-vivendi-theme-bold-constructs’ Possible values: 1. ‘nil’ (default) 2. ‘t’ Display several constructs in bold weight. This concerns keywords and other important aspects of code syntax. It also affects certain mode line indicators and command-line prompts. The default is to only use a bold weight when it is required. Additionally, and while not necessary, to define the precise weight for bold constructs, you can change the typographic intensity of the ‘bold’ face. The standard is a bold weight. It requires no further intervention. Assuming though that your typeface of choice supports a “semibold” weight, adding the following snippet to your init file should suffice. (set-face-attribute 'bold nil :weight 'semibold) Note that if you are switching themes, you need to re-evaluate this expression after the new theme is loaded. File: modus-themes.info, Node: Slanted constructs, Next: Syntax highlighting, Prev: Bold constructs, Up: Customization Options 4.2 Option for more slanted constructs ====================================== Symbol names: • ‘modus-operandi-theme-slanted-constructs’ • ‘modus-vivendi-theme-slanted-constructs’ Possible values: 1. ‘nil’ (default) 2. ‘t’ Choose to render more faces in slanted text (italics). This typically affects documentation strings and code comments. The default is to not use italics unless it is absolutely necessary. File: modus-themes.info, Node: Syntax highlighting, Next: No mixed fonts, Prev: Slanted constructs, Up: Customization Options 4.3 Option for faint code syntax highlighting ============================================= Symbol names: • ‘modus-operandi-theme-faint-syntax’ • ‘modus-vivendi-theme-faint-syntax’ Possible values: 1. ‘nil’ (default) 2. ‘t’ Use less saturated colors in programming modes for highlighting code syntax. The default is to use saturated colors. This option essentially affects the font-lock faces, so it may also have implications in other places that are hard-wired to rely directly on them instead of specifying their own faces (which could inherit from font-lock if that is the intent). The author is aware of ‘vc-dir’ as a case in point. File: modus-themes.info, Node: No mixed fonts, Next: Link underline, Prev: Syntax highlighting, Up: Customization Options 4.4 Option for no font mixing ============================= Symbol names: • ‘modus-operandi-theme-no-mixed-fonts’ • ‘modus-vivendi-theme-no-mixed-fonts’ Possible values: 1. ‘nil’ (default) 2. ‘t’ By default, the themes configure some spacing-sensitive faces, such as Org tables and code blocks, to always inherit from the ‘fixed-pitch’ face. This is to ensure that those constructs remain monospaced when users opt for something like the built-in ‘M-x variable-pitch-mode’. Otherwise the layout would appear broken. To disable this behaviour, set the option to ‘t’. Users may prefer to use another package for handling mixed typeface configurations, rather than letting the theme do it, perhaps because a purpose-specific package has extra functionality. Two possible options are ‘org-variable-pitch’ and ‘mixed-pitch’. File: modus-themes.info, Node: Link underline, Next: Link styles, Prev: No mixed fonts, Up: Customization Options 4.5 Option for no link underline (deprecated for ‘0.14.0’) ========================================================== Note: deprecated ahead of version ‘0.14.0’ (*note Option for links: Link styles.). Symbol names: • ‘modus-operandi-theme-no-link-underline’ • ‘modus-vivendi-theme-no-link-underline’ Possible values: 1. ‘nil’ (default) 2. ‘t’ Remove the underline effect from links, symbolic links, and buttons. The default is to apply an underline. File: modus-themes.info, Node: Link styles, Next: Comment styles, Prev: Link underline, Up: Customization Options 4.6 Option for links ==================== This option supersedes the “no link underline” one ahead of version ‘0.14.0’ (*note Option for no link underline: Link underline.). Symbol names: • ‘modus-operandi-theme-links’ • ‘modus-vivendi-theme-links’ Possible values: 1. ‘nil’ (default) 2. ‘faint’ 3. ‘neutral-underline’ 4. ‘faint-neutral-underline’ 5. ‘no-underline’ The default style (nil) for links is to apply an underline and a saturated color to the affected text. The color of the two is the same, which makes the link fairly prominent. Option ‘faint’ follows the same approach as the default, but uses less intense colors. Option ‘neutral-underline’ changes the underline’s color to a subtle gray, while retaining the default text color. Option ‘faint-neutral-underline’ combines a desaturated text color with a subtle gray underline. Option ‘no-underline’ removes link underlines altogether, while keeping their text color the same as the default. File: modus-themes.info, Node: Comment styles, Next: Command prompts, Prev: Link styles, Up: Customization Options 4.7 Option for comments ======================= This option is introduced ahead of version ‘0.14.0’. Symbol names: • ‘modus-operandi-theme-comments’ • ‘modus-vivendi-theme-comments’ Possible values: 1. ‘nil’ (default) 2. ‘green’ 3. ‘yellow’ By default (nil), comments in programming modes and elsewhere use a subtle gray color. Options ‘green’ or ‘yellow’ change it to a variant of the color they name. This is meant for those who prefer a clear distinction between the main text and comments. File: modus-themes.info, Node: Command prompts, Next: Mode line, Prev: Comment styles, Up: Customization Options 4.8 Option for command prompt styles ==================================== Symbol names: • ‘modus-operandi-theme-prompts’ • ‘modus-vivendi-theme-prompts’ Possible values: 1. ‘nil’ (default) 2. ‘subtle’ 3. ‘intense’ The symbols “subtle” and “intense” will apply a combination of accented background and foreground to the minibuffer and other REPL prompts (like ‘M-x shell’ and ‘M-x eshell’). The difference between the two is that the latter has a more pronounced/noticeable effect than the former. The default does not use any background for such prompts, while relying exclusively on an accented foreground color. File: modus-themes.info, Node: Mode line, Next: Completion UIs, Prev: Command prompts, Up: Customization Options 4.9 Option for mode line presentation ===================================== Symbol names: • ‘modus-operandi-theme-mode-line’ • ‘modus-vivendi-theme-mode-line’ Possible values: 1. ‘nil’ (default) 2. ‘3d’ 3. ‘moody’ The default value (‘nil’) produces a two-dimensional effect both for the active and inactive modelines. The differences between the two are limited to distinct shades of grayscale values, with the active being more intense than the inactive. A ‘3d’ symbol will make the active modeline look like a three-dimensional rectangle. Inactive modelines remain 2D, though they are slightly toned down relative to the default. This aesthetic is the same as what you get when you run Emacs without any customizations (‘emacs -Q’ on the command line). While ‘moody’ removes all box effects from the modelines and applies underline and overline properties instead. It also tones down a bit the inactive modelines. This is meant to optimize things for use with the moody package (https://github.com/tarsius/moody) (hereinafter referred to as “Moody”), though it can work fine even without it. Note that Moody does not expose any faces that the themes could style directly. Instead it re-purposes existing ones to render its tabs and ribbons. As such, there may be cases where the contrast ratio falls below the 7:1 target that the themes conform with (WCAG AAA). To hedge against this, we configure a fallback foreground for the ‘moody’ option, which will come into effect when the background of the modeline changes to something less accessible, such as Moody ribbons (read the doc string of ‘set-face-attribute’, specifically ‘:distant-foreground’). This fallback comes into effect when Emacs determines that the background and foreground of the given construct are too close to each other in terms of color distance. In effect, users would need to experiment with the variable ‘face-near-same-color-threshold’ to trigger the fallback color. We find that a value of ‘45000’ would suffice, contrary to the default ‘30000’. Do not set the value too high, because that would have the adverse effect of always overriding the default color (which has been carefully designed to be highly accessible). Furthermore, because Moody expects an underline and overline instead of a box style, it is recommended you also include this in your setup: (setq x-underline-at-descent-line t) File: modus-themes.info, Node: Completion UIs, Next: Fringes, Prev: Mode line, Up: Customization Options 4.10 Option for completion framework aesthetics =============================================== Symbol names: • ‘modus-operandi-theme-completions’ • ‘modus-vivendi-theme-completions’ Possible values: 1. ‘nil’ (default) 2. ‘moderate’ 3. ‘opinionated’ This is a special option that has different effects depending on the completion UI. The interfaces can be grouped in two categories, based on their default aesthetics: (i) those that only or mostly use foreground colors for their interaction model, and (ii) those that combine background and foreground values for some of their metaphors. The former category encompasses Icomplete, Ido, Selectrum as well as pattern matching styles like Orderless and Flx. The latter covers Helm, Ivy, and similar. A value of ‘nil’ will respect the metaphors of each completion framework. The symbol ‘moderate’ will apply a combination of background and foreground that is fairly subtle. For Icomplete and friends this constitutes a departure from their default aesthetics, however the difference is small. While Helm et al will appear slightly different than their original looks, as they are toned down a bit. The symbol ‘opinionated’ will apply color combinations that refashion the completion UI. For the Icomplete camp this means that intense background and foreground combinations are used: in effect their looks emulate those of Ivy and co. in their original style. Whereas the other group of packages will revert to an even more nuanced aesthetic with some additional changes to the choice of hues. To appreciate the scope of this customization option, you should spend some time with every one of the ‘nil’ (default), ‘moderate’, and ‘opinionated’ possibilities. File: modus-themes.info, Node: Fringes, Next: Line highlighting, Prev: Completion UIs, Up: Customization Options 4.11 Option for fringe visibility ================================= Symbol names: • ‘modus-operandi-theme-fringes’ • ‘modus-vivendi-theme-fringes’ Possible values: 1. ‘nil’ (default) 2. ‘subtle’ 3. ‘intense’ The “subtle” symbol will apply a grayscale background that is visible, yet close enough to the main background color. While the “intense” symbol will use a more noticeable grayscale background. The default is to use the same color as that of the main background, meaning that the fringes are not obvious though they still occupy the space given to them by ‘fringe-mode’. File: modus-themes.info, Node: Line highlighting, Next: Matching parentheses, Prev: Fringes, Up: Customization Options 4.12 Option for line highlighting (hl-line-mode) ================================================ Symbol names: • ‘modus-operandi-theme-intense-hl-line’ • ‘modus-vivendi-theme-intense-hl-line’ Possible values: 1. ‘nil’ (default) 2. ‘t’ Draw the current line of ‘hl-line-mode’ or its global equivalent in a more prominent background color. This would also affect several packages that enable ‘hl-line-mode’, such as ‘elfeed’ and ‘mu4e’. The default is to use a more subtle gray. File: modus-themes.info, Node: Matching parentheses, Next: Diffs, Prev: Line highlighting, Up: Customization Options 4.13 Option for parenthesis matching (show-paren-mode) ====================================================== Symbol names: • ‘modus-operandi-theme-intense-paren-match’ • ‘modus-vivendi-theme-intense-paren-match’ Possible values: 1. ‘nil’ (default) 2. ‘t’ Apply a more intense background to the matching parentheses (or delimiters). This affects tools such as the built-in ‘show-paren-mode’. The default is to use a subtle warm color for the background of those overlays. File: modus-themes.info, Node: Diffs, Next: Org mode blocks, Prev: Matching parentheses, Up: Customization Options 4.14 Option for diff buffer looks ================================= Symbol names: • ‘modus-operandi-theme-diffs’ • ‘modus-vivendi-theme-diffs’ Possible values: 1. ‘nil’ (default) 2. ‘desaturated’ 3. ‘fg-only’ By default the themes will apply richly colored backgrounds to the output of diffs, such as those of ‘diff-mode’, ‘ediff’, ‘smerge-mode’, and ‘magit’. These are color combinations of an accented background and foreground so that, for example, added lines have a pronounced green background with an appropriate shade of green for the affected text. Word-wise or “refined” changes follow this pattern but use different shades of those colors to remain distinct. A ‘desaturated’ value tones down all relevant color values. It still combines an accented background with an appropriate foreground, yet its overall impression is very subtle. Refined changes are a bit more intense to fulfil their intended function, though still less saturated than default. While ‘fg-only’ will remove all accented backgrounds and instead rely on color-coded text to denote changes. For instance, added lines use an intense green foreground, while their background is the same as the rest of the buffer. Word-wise highlights still use a background value which is, nonetheless, more subtle than its default equivalent. Concerning ‘magit’, an extra set of tweaks are introduced for the effect of highlighting the current diff hunk, so as to remain consistent with the overall experience of that mode. Expect changes that are consistent with the overall intent of the aforementioned. File: modus-themes.info, Node: Org mode blocks, Next: Heading styles, Prev: Diffs, Up: Customization Options 4.15 Option for org-mode block styles ===================================== Symbol names: • ‘modus-operandi-theme-org-blocks’ • ‘modus-vivendi-theme-org-blocks’ Possible values: 1. ‘nil’ (default) 2. ‘grayscale’ 3. ‘rainbow’ The default is to use the same background as the rest of the buffer for the contents of the block. A value of ‘grayscale’ will apply a subtle neutral gray background to the block’s contents. It will also extend to the edge of the window the background of the “begin” and “end” block delimiter lines (only relevant for Emacs versions >= 27 where the ’extend’ keyword is recognised by ‘set-face-attribute’). While ‘rainbow’ will instead use an accented background for the contents of the block. The exact color will depend on the programming language and is controlled by the ‘org-src-block-faces’ variable (refer to the theme’s source code for the current association list). This is most suitable for users who work on literate programming documents that mix and match several languages. Note that the “rainbow” blocks may require you to also reload the major-mode so that the colors are applied properly: use ‘M-x org-mode’ or ‘M-x org-mode-restart’ to refresh the buffer. Or start typing in each code block (inefficient at scale, but it still works). File: modus-themes.info, Node: Heading styles, Next: Scaled headings, Prev: Org mode blocks, Up: Customization Options 4.16 Option for headings’ overall style ======================================= This is defined as an alist and, therefore, uses a different approach than other customization options documented in this manual. Symbol names: • ‘modus-operandi-theme-headings’ • ‘modus-vivendi-theme-headings’ Possible values, which can be specified for each heading level (examples further below): • nil (default fallback option—covers all heading levels) • ‘t’ (default style for a single heading, when the fallback differs) • ‘no-bold’ • ‘line’ • ‘line-no-bold’ • ‘rainbow’ • ‘rainbow-line’ • ‘rainbow-line-no-bold’ • ‘highlight’ • ‘highlight-no-bold’ • ‘rainbow-highlight’ • ‘rainbow-highlight-no-bold’ • ‘section’ • ‘section-no-bold’ • ‘rainbow-section’ • ‘rainbow-section-no-bold’ To control faces per level from 1-8, use something like this (same for ‘modus-vivendi-theme-headings’): (setq modus-operandi-theme-headings '((1 . section) (2 . line) (3 . highlight) (t . rainbow-no-bold))) The above uses the ‘section’ value for heading levels 1, the ‘line’ for headings 2, ‘highlight’ for 3. All other levels fall back to ‘rainbow-line-no-bold’. To set a uniform value for all heading levels, use this pattern: ;; A given style for every heading (setq modus-operandi-theme-headings '((t . rainbow-line-no-bold))) ;; Default aesthetic for every heading (setq modus-operandi-theme-headings '((t . nil))) The default style for headings uses a fairly desaturated foreground value in combination with a bold typographic weight. To specify this style for a given level N (assuming you wish to have another fallback option), just specify the value ‘t’ like this: (setq modus-operandi-theme-headings '((1 . t) (2 . line) (t . rainbow-line-no-bold))) A description of all other possible styles: • ‘no-bold’ retains the default text color while removing the typographic weight. • ‘line’ is the same as the default plus an overline over the heading. • ‘line-no-bold’ is the same as ‘line’ without bold weight. • ‘rainbow’ uses a more colorful foreground in combination with bold weight. • ‘rainbow-line’ is the same as ‘rainbow’ plus an overline. • ‘rainbow-line-no-bold’ is the same as ‘rainbow-line’ without the bold weight. • ‘highlight’ retains the default style of a fairly desaturated foreground combined with a bold weight and adds to it a subtle accented background. • ‘highlight-no-bold’ is the same as ‘highlight’ without a bold weight. • ‘rainbow-highlight’ is the same as ‘highlight’ but with a more colorful foreground. • ‘rainbow-highlight-no-bold’ is the same as ‘rainbow-highlight’ without a bold weight. • ‘section’ retains the default looks and adds to them both an overline and a slightly accented background. It is, in effect, a combination of the ‘line’ and ‘highlight’ values. • ‘section-no-bold’ is the same as ‘section’ without a bold weight. • ‘rainbow-section’ is the same as ‘section’ but with a more colorful foreground. • ‘rainbow-section-no-bold’ is the same as ‘rainbow-section’ without a bold weight.“ File: modus-themes.info, Node: Scaled headings, Next: Headings' font, Prev: Heading styles, Up: Customization Options 4.17 Option for scaled headings =============================== Symbol names: • ‘modus-operandi-theme-scale-headings’ • ‘modus-vivendi-theme-scale-headings’ Possible values: 1. ‘nil’ (default) 2. ‘t’ Make headings larger in height relative to the main text. This is noticeable in modes like Org. The default is to use the same size for headings and body copy. * Menu: * Scaled heading sizes:: Specify rate of increase for scaled headings File: modus-themes.info, Node: Scaled heading sizes, Up: Scaled headings 4.17.1 Control the scale of headings ------------------------------------ In addition to toggles for enabling scaled headings, users can also specify a number of their own. • If it is a floating point, say, ‘1.5’, it is interpreted as a multiple of the base font size. This is the recommended method. • If it is an integer, it is read as an absolute font height. The number is basically the point size multiplied by ten. So if you want it to be ‘18pt’ you must pass ‘180’. Please understand that setting an absolute value is discouraged, as it will break the layout when you try to change font sizes with the built-in ‘text-scale-adjust’ command (see *note Font configurations: Font configs (DIY).). Below are the variables in their default values, using the floating point paradigm. The numbers are very conservative, but you are free to change them to your liking, such as ‘1.2’, ‘1.4’, ‘1.6’, ‘1.8’, ‘2.0’—or use a resource for finding a consistent scale: (setq modus-operandi-theme-scale-1 1.05 modus-operandi-theme-scale-2 1.1 modus-operandi-theme-scale-3 1.15 modus-operandi-theme-scale-4 1.2 modus-operandi-theme-scale-5 1.3) (setq modus-vivendi-theme-scale-1 1.05 modus-vivendi-theme-scale-2 1.1 modus-vivendi-theme-scale-3 1.15 modus-vivendi-theme-scale-4 1.2 modus-vivendi-theme-scale-5 1.3) Note that in earlier versions of Org, scaling would only increase the size of the heading, but not of keywords that were added to it, like “TODO”.

This means that it is possible to override the entire palette or subsets thereof (see the source code for the actual names and values). Example: ;; Redefine the values of those three variables for the given theme (setq modus-vivendi-theme-override-colors-alist '(("magenta" . "#ffaabb") ("magenta-alt" . "#ee88ff") ("magenta-alt-other" . "#bbaaff"))) If you want to be creative, you can define a minor mode that refashions the themes on demand. The following is a minor mode that gets activated on demand. We combine it with the function to switch between Modus Operandi and Modus Vivendi (see *note Toggle between the themes on demand:: for a basic command, and/or *note Configure options prior to loading:: for a more comprehensive setup).

Currently this applies to ‘org-mode’ and ‘markdown-mode’. In practice it means that the user can safely opt for a more prose-friendly proportionately spaced typeface as their default, while letting spacing-sensitive elements like tables and inline code always use a monospaced font, by inheriting from the ‘fixed-pitch’ face. Users can try the built-in ‘M-x variable-pitch-mode’ to see the effect in action. To make everything use your desired font families, you need to configure the ‘variable-pitch’ (proportional spacing) and ‘fixed-pitch’ (monospaced) faces respectively. It may also be convenient to set your main typeface by configuring the ‘default’ face the same way. Put something like this in your initialization file (make sure to read the documentation of ‘set-face-attribute’, with ‘M-x describe-function’): ;; Main typeface (set-face-attribute 'default nil :family "DejaVu Sans Mono" :height 110) ;; Proportionately spaced typeface (set-face-attribute 'variable-pitch nil :family "DejaVu Serif" :height 1.0) ;; Monospaced typeface (set-face-attribute 'fixed-pitch nil :family "DejaVu Sans Mono" :height 1.0) Note the differences in the ‘:height’ property. The ‘default’ face must specify an absolute value, which is the point size × 10. So if you want to use a font at point size ‘11’, you set the height at ‘110’.(1) Whereas every other face must have a value that is relative to the default, represented as a floating point (if you use an integer, say, ‘15’ then that means an absolute height). This is of paramount importantance: it ensures that all fonts can scale gracefully when using something like the ‘text-scale-adjust’ command which only operates on the base font size (i.e. the ‘default’ face’s absolute height). An alternative syntax for the ‘default’ face, is to pass all typeface parameters directly to a ‘font’ property.(2) Note that here we use a standard point size: (set-face-attribute 'default nil :font "DejaVu Sans Mono-11") Again, remember to only ever specify an absolute height for the ‘default’. ---------- Footnotes ---------- (1) ‘:height’ values do not need to be rounded to multiples of ten: the likes of ‘115’ are perfectly valid—some typefaces will change to account for those finer increments. (2) Has the benefit of accepting ‘fontconfig’ parameters (GNU/Linux), such as ‘"DejaVu Sans Mono-11:hintstyle=hintslight:autohint=false"’. <https://www.freedesktop.org/software/fontconfig/fontconfig-user.html> File: modus-themes.info, Node: Org user faces (DIY), Prev: Font configs (DIY), Up: Advanced customization (do-it-yourself) 5.3 Org user faces (DIY) ======================== Users of ‘org-mode’ have the option to configure various keywords and priority cookies to better match their workflow. User options are ‘org-todo-keyword-faces’ and ‘org-priority-faces’. As those are meant to be custom faces, it would be futile to have the themes try to guess what each user would want to use, which keywords to target, and so on. Instead, we can provide guidelines on how to customize things to one’s liking with the intent of retaining the overall aesthetics of the theme. Please bear in mind that the end result of those is not controlled by the active theme but by how Org maps faces to its constructs. Editing those while ‘org-mode’ is active requires ‘M-x org-mode-restart’ for changes to take effect. Let us assume you wish to visually differentiate your keywords. You have something like this: (setq org-todo-keywords '((sequence "TODO(t)" "|" "DONE(D)" "CANCEL(C)") (sequence "MEET(m)" "|" "MET(M)") (sequence "STUDY(s)" "|" "STUDIED(S)") (sequence "WRITE(w)" "|" "WROTE(W)"))) You could then use a variant of the following to inherit from a face that uses the styles you want and also to preserve the properties applied by the ‘org-todo’ face: (setq org-todo-keyword-faces '(("MEET" . '(font-lock-preprocessor-face org-todo)) ("STUDY" . '(font-lock-variable-name-face org-todo)) ("WRITE" . '(font-lock-type-face org-todo)))) This will refashion the keywords you specify, while letting the other items in ‘org-todo-keywords’ use their original styles (which are defined in the ‘org-todo’ and ‘org-done’ faces). If you want back the defaults, try specifying just the ‘org-todo’ face: (setq org-todo-keyword-faces '(("MEET" . org-todo) ("STUDY" . org-todo) ("WRITE" . org-todo))) When you inherit from multiple faces, you need to quote the list as shown further above. The order is important: the last item is applied over the previous ones. If you do not want to blend multiple faces, you do not need a quoted list. A pattern of ‘keyword . face’ would suffice. Both approaches can be used simultaneously, as illustrated in this configuration of the priority cookies: (setq org-priority-faces '((?A . '(org-scheduled-today org-priority)) (?B . org-priority) (?C . '(shadow org-priority)))) To find all the faces that are loaded in your current Emacs session, use ‘M-x list-faces-display’. Also try ‘M-x describe-variable’ and then specify the name of each of those Org variables demonstrated above. Their documentation strings will offer you further guidance. Furthermore, consider reading the “Notes for aspiring Emacs theme developers”, published on 2020-08-28 by me (Protesilaos Stavrou): <https://protesilaos.com/codelog/2020-08-28-notes-emacs-theme-devs/>.

File: modus-themes.info, Node: Notes for individual packages, Next: Contributing, Prev: Face coverage, Up: Top 7 Notes for individual packages ******************************* This section covers information that may be of interest to users of individual packages. * Menu: * Note on company-mode overlay pop-up:: * Note for ERC escaped color sequences:: * Note for powerline or spaceline:: * Note on shr colors:: * Note for Helm grep:: * Note on vc-annotate-background-mode:: File: modus-themes.info, Node: Note on company-mode overlay pop-up, Next: Note for ERC escaped color sequences, Up: Notes for individual packages 7.1 Note on company-mode overlay pop-up ======================================= By default, the ‘company-mode’ pop-up that lists completion candidates is drawn using an overlay. This creates alignment issues every time it is placed above a piece of text that has a different height than the default. The solution recommended by the project’s maintainer is to use an alternative front-end for drawing the pop-up which uses child frames instead of overlays.(1)(2) ---------- Footnotes ---------- (1) <https://github.com/company-mode/company-mode/issues/1010> (2) <https://github.com/tumashu/company-posframe/> File: modus-themes.info, Node: Note for ERC escaped color sequences, Next: Note for powerline or spaceline, Prev: Note on company-mode overlay pop-up, Up: Notes for individual packages 7.2 Note for ERC escaped color sequences ======================================== The built-in IRC client ‘erc’ has the ability to colorise any text using escape sequences that start with ‘^C’ (inserted with ‘C-q C-c’) and are followed by a number for the foreground and background.(1) Possible numbers are 0-15, with the first entry being the foreground and the second the background, separated by a comma. Like this ‘^C1,6’. The minimum setup is this: (add-to-list 'erc-modules 'irccontrols) (setq erc-interpret-controls-p t erc-interpret-mirc-color t) As this allows users to make arbitrary combinations, it is impossible to guarantee a consistently high contrast ratio. All we can we do is provide guidance on the combinations that satisfy the accessibility standard of the themes: Modus Operandi Use foreground color 1 for all backgrounds from 2-15. Like so: ‘C-q C-c1,N’ where ‘N’ is the background. Modus Vivendi Use foreground color 0 for all backgrounds from 2-13. Use foreground ‘1’ for backgrounds 14, 15. Colors 0 and 1 are white and black respectively. So combine them together, if you must. ---------- Footnotes ---------- (1) This page explains the basics, though it is not specific to Emacs: <https://www.mirc.com/colors.html> File: modus-themes.info, Node: Note for powerline or spaceline, Next: Note on shr colors, Prev: Note for ERC escaped color sequences, Up: Notes for individual packages 7.3 Note for powerline or spaceline =================================== Both Powerline and Spaceline package users will likely need to use the command ‘powerline-reset’ whenever they make changes to their themes and/or modeline setup. File: modus-themes.info, Node: Note on shr colors, Next: Note for Helm grep, Prev: Note for powerline or spaceline, Up: Notes for individual packages 7.4 Note on shr colors ====================== Emacs’ HTML rendering mechanism (‘shr’) may need explicit configuration to respect the theme’s colors instead of whatever specifications the webpage provides. Consult ‘C-h v shr-use-colors’. File: modus-themes.info, Node: Note for Helm grep, Next: Note on vc-annotate-background-mode, Prev: Note on shr colors, Up: Notes for individual packages 7.5 Note for Helm grep ====================== There is one face from the Helm package that is meant to highlight the matches of a grep or grep-like command (‘ag’ or ‘ripgrep’). It is ‘helm-grep-match’. However, this face can only apply when the user does not pass ‘--color=always’ as a command-line option for their command. Here is the docstring for that face, which is defined in the ‘helm-grep.el’ library (view a library with ‘M-x find-library’). Face used to highlight grep matches. Have no effect when grep backend use “–color=” The user must either remove ‘--color’ from the flags passed to the grep function, or explicitly use ‘--color=never’ (or equivalent). Helm provides user-facing customization options for controlling the grep function’s parameters, such as ‘helm-grep-default-command’ and ‘helm-grep-git-grep-command’. When ‘--color=always’ is in effect, the grep output will use red text in bold letter forms to present the matching part in the list of candidates. That style still meets the contrast ratio target of >= 7:1 (accessibility standard WCAG AAA), because it draws the reference to ANSI color number 1 (red) from the already-supported array of ‘ansi-color-names-vector’. File: modus-themes.info, Node: Note on vc-annotate-background-mode, Prev: Note for Helm grep, Up: Notes for individual packages 7.6 Note on vc-annotate-background-mode ======================================= Due to the unique way ‘vc-annotate’ (‘C-x v g’) applies colors, support for its background mode (‘vc-annotate-background-mode’) is disabled at the theme level. Normally, such a drastic measure should not belong in a theme: assuming the user’s preferences is bad practice. However, it has been deemed necessary in the interest of preserving color contrast accessibility while still supporting a useful built-in tool. If there actually is a way to avoid such a course of action, without prejudice to the accessibility standard of this project, then please report as much or send patches (see *note Contributing::).

PREAMBLE The purpose of this License is to make a manual, textbook, or other functional and useful document "free" in the sense of freedom: to assure everyone the effective freedom to copy and redistribute it, with or without modifying it, either commercially or noncommercially. Secondarily, this License preserves for the author and publisher a way to get credit for their work, while not being considered responsible for modifications made by others. This License is a kind of "copyleft", which means that derivative works of the document must themselves be free in the same sense. It complements the GNU General Public License, which is a copyleft license designed for free software. We have designed this License in order to use it for manuals for free software, because free software needs free documentation: a free program should come with manuals providing the same freedoms that the software does. But this License is not limited to software manuals; it can be used for any textual work, regardless of subject matter or whether it is published as a printed book. We recommend this License principally for works whose purpose is instruction or reference. 1. APPLICABILITY AND DEFINITIONS This License applies to any manual or other work, in any medium, that contains a notice placed by the copyright holder saying it can be distributed under the terms of this License. Such a notice grants a world-wide, royalty-free license, unlimited in duration, to use that work under the conditions stated herein. The "Document", below, refers to any such manual or work. Any member of the public is a licensee, and is addressed as "you". You accept the license if you copy, modify or distribute the work in a way requiring permission under copyright law. A "Modified Version" of the Document means any work containing the Document or a portion of it, either copied verbatim, or with modifications and/or translated into another language. A "Secondary Section" is a named appendix or a front-matter section of the Document that deals exclusively with the relationship of the publishers or authors of the Document to the Document's overall subject (or to related matters) and contains nothing that could fall directly within that overall subject. (Thus, if the Document is in part a textbook of mathematics, a Secondary Section may not explain any mathematics.) The relationship could be a matter of historical connection with the subject or with related matters, or of legal, commercial, philosophical, ethical or political position regarding them. The "Invariant Sections" are certain Secondary Sections whose titles are designated, as being those of Invariant Sections, in the notice that says that the Document is released under this License. If a section does not fit the above definition of Secondary then it is not allowed to be designated as Invariant. The Document may contain zero Invariant Sections. If the Document does not identify any Invariant Sections then there are none. The "Cover Texts" are certain short passages of text that are listed, as Front-Cover Texts or Back-Cover Texts, in the notice that says that the Document is released under this License. A Front-Cover Text may be at most 5 words, and a Back-Cover Text may be at most 25 words. A "Transparent" copy of the Document means a machine-readable copy, represented in a format whose specification is available to the general public, that is suitable for revising the document straightforwardly with generic text editors or (for images composed of pixels) generic paint programs or (for drawings) some widely available drawing editor, and that is suitable for input to text formatters or for automatic translation to a variety of formats suitable for input to text formatters. A copy made in an otherwise Transparent file format whose markup, or absence of markup, has been arranged to thwart or discourage subsequent modification by readers is not Transparent. An image format is not Transparent if used for any substantial amount of text. A copy that is not "Transparent" is called "Opaque". Examples of suitable formats for Transparent copies include plain ASCII without markup, Texinfo input format, LaTeX input format, SGML or XML using a publicly available DTD, and standard-conforming simple HTML, PostScript or PDF designed for human modification. Examples of transparent image formats include PNG, XCF and JPG. Opaque formats include proprietary formats that can be read and edited only by proprietary word processors, SGML or XML for which the DTD and/or processing tools are not generally available, and the machine-generated HTML, PostScript or PDF produced by some word processors for output purposes only. The "Title Page" means, for a printed book, the title page itself, plus such following pages as are needed to hold, legibly, the material this License requires to appear in the title page. For works in formats which do not have any title page as such, "Title Page" means the text near the most prominent appearance of the work's title, preceding the beginning of the body of the text. The "publisher" means any person or entity that distributes copies of the Document to the public. A section "Entitled XYZ" means a named subunit of the Document whose title either is precisely XYZ or contains XYZ in parentheses following text that translates XYZ in another language. (Here XYZ stands for a specific section name mentioned below, such as "Acknowledgements", "Dedications", "Endorsements", or "History".) To "Preserve the Title" of such a section when you modify the Document means that it remains a section "Entitled XYZ" according to this definition. The Document may include Warranty Disclaimers next to the notice which states that this License applies to the Document. These Warranty Disclaimers are considered to be included by reference in this License, but only as regards disclaiming warranties: any other implication that these Warranty Disclaimers may have is void and has no effect on the meaning of this License. 2. VERBATIM COPYING You may copy and distribute the Document in any medium, either commercially or noncommercially, provided that this License, the copyright notices, and the license notice saying this License applies to the Document are reproduced in all copies, and that you add no other conditions whatsoever to those of this License. You may not use technical measures to obstruct or control the reading or further copying of the copies you make or distribute. However, you may accept compensation in exchange for copies. If you distribute a large enough number of copies you must also follow the conditions in section 3. You may also lend copies, under the same conditions stated above, and you may publicly display copies. 3. COPYING IN QUANTITY If you publish printed copies (or copies in media that commonly have printed covers) of the Document, numbering more than 100, and the Document's license notice requires Cover Texts, you must enclose the copies in covers that carry, clearly and legibly, all these Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on the back cover. Both covers must also clearly and legibly identify you as the publisher of these copies. The front cover must present the full title with all words of the title equally prominent and visible. You may add other material on the covers in addition. Copying with changes limited to the covers, as long as they preserve the title of the Document and satisfy these conditions, can be treated as verbatim copying in other respects. If the required texts for either cover are too voluminous to fit legibly, you should put the first ones listed (as many as fit reasonably) on the actual cover, and continue the rest onto adjacent pages. If you publish or distribute Opaque copies of the Document numbering more than 100, you must either include a machine-readable Transparent copy along with each Opaque copy, or state in or with each Opaque copy a computer-network location from which the general network-using public has access to download using public-standard network protocols a complete Transparent copy of the Document, free of added material. If you use the latter option, you must take reasonably prudent steps, when you begin distribution of Opaque copies in quantity, to ensure that this Transparent copy will remain thus accessible at the stated location until at least one year after the last time you distribute an Opaque copy (directly or through your agents or retailers) of that edition to the public. It is requested, but not required, that you contact the authors of the Document well before redistributing any large number of copies, to give them a chance to provide you with an updated version of the Document. 4. MODIFICATIONS You may copy and distribute a Modified Version of the Document under the conditions of sections 2 and 3 above, provided that you release the Modified Version under precisely this License, with the Modified Version filling the role of the Document, thus licensing distribution and modification of the Modified Version to whoever possesses a copy of it. In addition, you must do these things in the Modified Version: A. Use in the Title Page (and on the covers, if any) a title distinct from that of the Document, and from those of previous versions (which should, if there were any, be listed in the History section of the Document). You may use the same title as a previous version if the original publisher of that version gives permission. B. List on the Title Page, as authors, one or more persons or entities responsible for authorship of the modifications in the Modified Version, together with at least five of the principal authors of the Document (all of its principal authors, if it has fewer than five), unless they release you from this requirement. C. State on the Title page the name of the publisher of the Modified Version, as the publisher. D. Preserve all the copyright notices of the Document. E. Add an appropriate copyright notice for your modifications adjacent to the other copyright notices. F. Include, immediately after the copyright notices, a license notice giving the public permission to use the Modified Version under the terms of this License, in the form shown in the Addendum below. G. Preserve in that license notice the full lists of Invariant Sections and required Cover Texts given in the Document's license notice. H. Include an unaltered copy of this License. I. Preserve the section Entitled "History", Preserve its Title, and add to it an item stating at least the title, year, new authors, and publisher of the Modified Version as given on the Title Page. If there is no section Entitled "History" in the Document, create one stating the title, year, authors, and publisher of the Document as given on its Title Page, then add an item describing the Modified Version as stated in the previous sentence. J. Preserve the network location, if any, given in the Document for public access to a Transparent copy of the Document, and likewise the network locations given in the Document for previous versions it was based on. These may be placed in the "History" section. You may omit a network location for a work that was published at least four years before the Document itself, or if the original publisher of the version it refers to gives permission. K. For any section Entitled "Acknowledgements" or "Dedications", Preserve the Title of the section, and preserve in the section all the substance and tone of each of the contributor acknowledgements and/or dedications given therein. L. Preserve all the Invariant Sections of the Document, unaltered in their text and in their titles. Section numbers or the equivalent are not considered part of the section titles. M. Delete any section Entitled "Endorsements". Such a section may not be included in the Modified Version. N. Do not retitle any existing section to be Entitled "Endorsements" or to conflict in title with any Invariant Section. O. Preserve any Warranty Disclaimers. If the Modified Version includes new front-matter sections or appendices that qualify as Secondary Sections and contain no material copied from the Document, you may at your option designate some or all of these sections as invariant. To do this, add their titles to the list of Invariant Sections in the Modified Version's license notice. These titles must be distinct from any other section titles. You may add a section Entitled "Endorsements", provided it contains nothing but endorsements of your Modified Version by various parties--for example, statements of peer review or that the text has been approved by an organization as the authoritative definition of a standard. You may add a passage of up to five words as a Front-Cover Text, and a passage of up to 25 words as a Back-Cover Text, to the end of the list of Cover Texts in the Modified Version. Only one passage of Front-Cover Text and one of Back-Cover Text may be added by (or through arrangements made by) any one entity. If the Document already includes a cover text for the same cover, previously added by you or by arrangement made by the same entity you are acting on behalf of, you may not add another; but you may replace the old one, on explicit permission from the previous publisher that added the old one. The author(s) and publisher(s) of the Document do not by this License give permission to use their names for publicity for or to assert or imply endorsement of any Modified Version. 5. COMBINING DOCUMENTS You may combine the Document with other documents released under this License, under the terms defined in section 4 above for modified versions, provided that you include in the combination all of the Invariant Sections of all of the original documents, unmodified, and list them all as Invariant Sections of your combined work in its license notice, and that you preserve all their Warranty Disclaimers. The combined work need only contain one copy of this License, and multiple identical Invariant Sections may be replaced with a single copy. If there are multiple Invariant Sections with the same name but different contents, make the title of each such section unique by adding at the end of it, in parentheses, the name of the original author or publisher of that section if known, or else a unique number. Make the same adjustment to the section titles in the list of Invariant Sections in the license notice of the combined work. In the combination, you must combine any sections Entitled "History" in the various original documents, forming one section Entitled "History"; likewise combine any sections Entitled "Acknowledgements", and any sections Entitled "Dedications". You must delete all sections Entitled "Endorsements". 6. COLLECTIONS OF DOCUMENTS You may make a collection consisting of the Document and other documents released under this License, and replace the individual copies of this License in the various documents with a single copy that is included in the collection, provided that you follow the rules of this License for verbatim copying of each of the documents in all other respects. You may extract a single document from such a collection, and distribute it individually under this License, provided you insert a copy of this License into the extracted document, and follow this License in all other respects regarding verbatim copying of that document. 7. AGGREGATION WITH INDEPENDENT WORKS A compilation of the Document or its derivatives with other separate and independent documents or works, in or on a volume of a storage or distribution medium, is called an "aggregate" if the copyright resulting from the compilation is not used to limit the legal rights of the compilation's users beyond what the individual works permit. When the Document is included in an aggregate, this License does not apply to the other works in the aggregate which are not themselves derivative works of the Document. If the Cover Text requirement of section 3 is applicable to these copies of the Document, then if the Document is less than one half of the entire aggregate, the Document's Cover Texts may be placed on covers that bracket the Document within the aggregate, or the electronic equivalent of covers if the Document is in electronic form. Otherwise they must appear on printed covers that bracket the whole aggregate. 8. TRANSLATION Translation is considered a kind of modification, so you may distribute translations of the Document under the terms of section 4. Replacing Invariant Sections with translations requires special permission from their copyright holders, but you may include translations of some or all Invariant Sections in addition to the original versions of these Invariant Sections. You may include a translation of this License, and all the license notices in the Document, and any Warranty Disclaimers, provided that you also include the original English version of this License and the original versions of those notices and disclaimers. In case of a disagreement between the translation and the original version of this License or a notice or disclaimer, the original version will prevail. If a section in the Document is Entitled "Acknowledgements", "Dedications", or "History", the requirement (section 4) to Preserve its Title (section 1) will typically require changing the actual title. 9. TERMINATION You may not copy, modify, sublicense, or distribute the Document except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, or distribute it is void, and will automatically terminate your rights under this License. However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, receipt of a copy of some or all of the same material does not give you any rights to use it. 10. FUTURE REVISIONS OF THIS LICENSE The Free Software Foundation may publish new, revised versions of the GNU Free Documentation License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. See https://www.gnu.org/licenses/. Each version of the License is given a distinguishing version number. If the Document specifies that a particular numbered version of this License "or any later version" applies to it, you have the option of following the terms and conditions either of that specified version or of any later version that has been published (not as a draft) by the Free Software Foundation. If the Document does not specify a version number of this License, you may choose any version ever published (not as a draft) by the Free Software Foundation. If the Document specifies that a proxy can decide which future versions of this License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Document. 11. RELICENSING "Massive Multiauthor Collaboration Site" (or "MMC Site") means any World Wide Web server that publishes copyrightable works and also provides prominent facilities for anybody to edit those works. A public wiki that anybody can edit is an example of such a server. A "Massive Multiauthor Collaboration" (or "MMC") contained in the site means any set of copyrightable works thus published on the MMC site. "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0 license published by Creative Commons Corporation, a not-for-profit corporation with a principal place of business in San Francisco, California, as well as future copyleft versions of that license published by that same organization. "Incorporate" means to publish or republish a Document, in whole or in part, as part of another Document. An MMC is "eligible for relicensing" if it is licensed under this License, and if all works that were first published under this License somewhere other than this MMC, and subsequently incorporated in whole or in part into the MMC, (1) had no cover texts or invariant sections, and (2) were thus incorporated prior to November 1, 2008. The operator of an MMC Site may republish an MMC contained in the site under CC-BY-SA on the same site at any time before August 1, 2009, provided the MMC is eligible for relicensing. ADDENDUM: How to use this License for your documents To use this License in a document you have written, include a copy of the License in the document and put the following copyright and license notices just after the title page: Copyright (c) YEAR YOUR NAME. Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.3 or any later version published by the Free Software Foundation; with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. A copy of the license is included in the section entitled "GNU Free Documentation License". If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, replace the "with...Texts." line with this: with the Invariant Sections being LIST THEIR TITLES, with the Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST. If you have Invariant Sections without Cover Texts, or some other combination of the three, merge those two alternatives to suit the situation. If your document contains nontrivial examples of program code, we recommend releasing these examples in parallel under your choice of free software license, such as the GNU General Public License, to permit their use in free software.
