Prompy

Is my bash prompt written in rust.

It's also a playground I used to learn a bit more about a certain architectural design which is in a certain way total over engineering for a bash prompt command.

As this is solely meant for personal use this only runs on linux, might not be compatible with all terminals and might not work with a non-bash shell.

I will response to issues but if the issue doesn't affect me the response is not unlikely something on the line of "I apologize but I won't fix this/add this feature".

Usage

For trying it out use:

> eval $(cargo run --release -- --bash-setup)

For a more permanent setup:

1. build the binary cargo build --release
2. get binary from ./target/release/prompty
3. add following to .bashrc: eval $(prompty --bash-setup) Where prompty should be a path to the prompty binary.

The --bash-setup option makes prompty a bash snipped consisting of:

1. A assignment to PS1 in a form similar to PS1='$(prompty $COLUMN)'. Note that instead of promptya absolute path the thepromptybinary will be used determined by rustsstd::env::current_exec()` function.
2. Add a function called g which works like cd but will set the __PS_PATH_TOP environment variable, which prompty uses to trim the displayed current working dir (if possible, if not it will try the value of $HOME if not it just displays the full path).
   • note that the g function is likely to be extended/changed in the future and might collide with your own aliases/programs. A non hard-coded config is possible but currently not given as I simply don't need it.
