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)
