New File Processor

nfp is a tool that watches directories for new files and calls user-defined commands on them. Like automatically calling an upload script on a file exported from a graphics editor to a specified directory.

Config

nfp is configured by a TOML file like this:

[[processors]]
path = "/home/user/.local/share/nfp/export1"
depth = 1
command = "python"
args = ["/path/to/upload.py", "%f"]  # %f is replaced with a filename
keep_file = true
debounce = 500

You can have more than one [[processors]] sections.

Options:

• depth is a recursion depth of sub-directories to watch. Defaults to 0, meaning watching only the parent directory itself. nfp will automatically pick up changes in the directory tree.

• keep_file prevents automatic deletion of a processed file.

• debounce is useful for producers with a habit of re-opening and overwriting files several times in quick succession. This specifies a timeout in milliseconds to wait after the file was last written and closed before calling a processing command on it.

The config file is looked up in nfp/config.toml under the common config directory on you platform (using directories crate to resolve that.)

Runnning

In the simplest case it's just:

nfp

You probably want to run that on start-up and redirect stdout/stderr somewhere sensible.

nfp >> ~/.local/state/nfp/log 2>&1

You could also just run it via nohup and simply close the terminal window after that.
