Usage

• Built on rust nightly-2017-02-21

• Copy config/rushrc.sh to ~/.rushrc

Config File

Rusty uses toml to customize it's use. Here are some of the configuration options:

Prompts

[prompt]
left = "%U@%H %L %R"

The characters following the % can all be used or not. Here is what they stand for:

• %U = Current user
• %H = Hostname
• %L = Current Working Directory
• %R = Whether you are root or not

They can be arranged in any order you desire. Any extra characters in the field will just be put in the prompt. Following the above example for my computer the prompt would look like:

zethra@linux-box ~/ $

Aliases

The [alias] is required in the config file but anything underneath is optional. Below is an example of how it would look in your file in order to use them:

[alias]
gpm = "git push master"
gc = "git commit"
ls = "ls -al"

Enivronment Variables

The [env_var] is required in the config file but anything underneath is optional. Below is an example of how it would look in your file in order to use them:

[env_var]
EDITOR = "vim"

Inspiration

Rush was orininally a fork of Rusty although I've changed a lot since then. My peg grammar was largly taken from js-shell-parse.
