pathvar-rs

An executable that facilitates idempotent modifications to your PATH variable.

Motivation

Note that the idiomatic way to add folders to your PATH is to add lines like the following to your ~/.bashrc:

PATH=~/bin:$PATH
PATH=$PATH:~/bin

This means that if you run source ~/.bashrc, ~/bin will be added to the PATH again, which is not ideal. Note this also effectively happens when you run tmux new window, so successive tmux windows have longer and longer PATH variables under the standard idiom.

Installation

Run cargo install pathvar, which will add pathvar to your PATH.

Command: insert

This will prepend ~/bin (expanded) to the $PATH if it is not already present:

PATH=$(pathvar insert ~/bin)

Command: add

This will append ~/bin (expanded) to the $PATH if it is not already present:

PATH=$(pathvar add ~/bin)
