The all important =PATH= environment variable, needs my special =bin= directory.

My Apple Macbook screws up my =PATH= by having =/etc/profile= (that runs after my =~/.zshenv=) /pre-pend/ system directories like =/bin= and =/usr/bin= /after/ I’ve set up my =PATH= environment variable. So, in my own =.zprofile=, I reverse it:
|

|

#+BEGIN_SRC sh :tangle ~/.zprofile :shebang #!/bin/zsh
|

# Reverse the PATH variable

reversed_path=$(echo $PATH | tr ':' '\n' | tac | tr '\n' ':')

* Homebrew
|
||||
When using Homebrew on a Mac, we need to add its =PATH= and environment variables. This is typically done by running the command:
|
||||
|
||||
#+BEGIN_SRC zsh :tangle no
|
||||
eval $(brew shellenv zsh)
|
||||
#+END_SRC
|
||||
|
||||
We want to add the path and environment variables into the =~/.zshenv= file, but this file should not contain any logic or code. So, let’s run the command /from Emacs/, and store the results in the file.
|
||||
|
||||
The full script to run is:
|
||||
|
||||
#+BEGIN_SRC zsh :tangle no :results file :file ~/.zshenv_brew
|
||||
echo '# -*- mode:sh; -*-'
|
||||
if which brew >/dev/null
|
||||
then
|
||||
if [[ -d /opt/homebrew ]]
|
||||
then
|
||||
/opt/homebrew/bin/brew shellenv zsh

||||
brew shellenv zsh

|
||||
#+END_SRC

Seems that if I want the GNU versions (instead of the old ones supplied by Apple), I have to do it myself:
|
||||
|
||||
#+BEGIN_SRC zsh :tangle no :results file :file ~/.zshenv_gnu
|
||||
echo '# -*- mode:sh; -*-'
|
