# Live apps that can have text editor widgets

# Thin programming environment for making edits to "live" LÖVE apps
Use this app to communicate over a back-channel with LÖVE apps that follow a
certain protocol:
  * https://codeberg.org/akkartik/luaML.love
  * ...
Communication happens over temporary files in the file system that should live
in an internal directory, but might end up in your home directory. Using these
files, driver.love can make changes to these apps without needing to restart
them.

A template repo for building live apps that juggle text editor widgets. The
editors support copy/paste, search, infinite undo, etc. You can't quite modify
editor functionality live (yet?).

To run from the terminal, [pass this directory to LÖVE](https://love2d.org/wiki/Getting_Started#Running_Games),
optionally with a file path to edit.
Alternatively, turn it into a .love file you can double-click on:
```
$ zip -r /tmp/text.love *.lua
```

By default, it reads/writes the file `lines.txt` in your default
user/home directory (`https://love2d.org/wiki/love.filesystem.getUserDirectory`).

To run from the terminal, [pass this directory to LÖVE](https://love2d.org/wiki/Getting_Started#Running_Games).

To open a different file, drop it on the app window.

You must have an app running that can be communicated; otherwise driver.love
will hang until it finds one, and might need to be force-quit. (Also, bad
things will happen if you have _more than_ a single such app running.)

While editing text:

* `f4` to send current buffer to some app. (Run only one such live app at a
  time.)
* `ctrl+l` to browse a list of definitions within the app that are available
  to edit. (Not everything will be.)
* `ctrl+d` to delete a definition.
While editing a buffer:

* `alt+right`/`alt+left` to jump to the next/previous word, respectively

* `ctrl+right`/`ctrl+left` to jump to the next/previous word, respectively
