contrail

Highly configurable shell prompter, inspired by powerline-shell and bash-powerline.

Customizations are made via a TOML file.

Disclaimer: A large part of this program's functionality depends on the user's shell, font, and terminal emulator. Each shell and terminal emulator supports different effects. Therefore, there may be some options that do not work with your setup! Weird/missing symbols can be fixed by changing the config or your terminal's font.

Works on BASH and ZSH shells.

Expect frequent breaking changes.

Installation

You need the latest stable version of Rust (install with rustup).

Ensure your $PATH includes $HOME/.cargo/bin.

Clone the repository and install with cargo:

git clone https://github.com/ben01189998819991197253/contrail ~/contrail
cd ~/contrail
cargo test && cargo install
# If updating, you may need to do `cargo install --force`

BASH

In your ~/.bashrc:

# ~/.bashrc
ps1() {
    PS1="$(contrail -e $? --config $HOME/path/to/config.toml) "
}

PROMPT_COMMAND="ps1; $PROMPT_COMMAND"

ZSH

In your ~/.zshrc

# ~/.zshrc
precmd() {
    PS1="$(contrail -e $? --shell "zsh" --config $HOME/path/to/config.toml) "
}

Restart/re-launch your terminal emulator. You'll know if it's working correctly.

contrail -h and contrail -V will print the help information and the version number, respectively.

Configuration

Contrail can be told about the location of the config file with the --config option.

Each part of the prompt is split up into "modules". A typical prompt might have a "cwd" module (shows the current working directory), a "git" module (shows the current state of a git repo), and a "prompt" module (changes color depending on the last exit code).

Contributing

...is welcomed! Please submit any issues and pull requests, although do run your code through rustfmt first, please.

"Help, when I try to run contrail it just crashes!"

Make 100% sure your config file is syntactically correct TOML. Otherwise, file an issue or dig into the source code and try to fix it :)
