Get Function Into PS1 (Zsh)?
Solution 1
You have to include
setopt PROMPT_SUBST
in your .zshrc
, man zshall
explains it in the PROMPT EXPANSION section:
If the PROMPT_SUBST option is set, the prompt string is first subjected to parameter expansion, command substitution and arithmetic expansion.
Solution 2
Actually your problem was not just setting PROMPT_SUBST
: you use double quotes in your script forcing the evaluation of the function when you set the PROMPT
variables. You only want evaluation when the prompt is computed that is you must use single quotes.
Solution 3
As akira says, you have to use prompt subst. This is my early code (still working on it):
setopt PROMPT_SUBST
PROMPT='$(parse_git_branch)'
or better
setopt PROMPT_SUBST
PROMPT='[$PR_MAGENTA%n$PR_NO_COLOR@$PR_GREEN%U%m%u$PR_NO_COLOR:$PR_RED%2c$PR_NO_COLOR]$(parse_git_branch) %(!.#.$)'

This works in
bash
(parse_git_branch
is a defined function)export PS1="\$(parse_git_branch)"
But I cannot figure out the equivalent in
zsh
.Note: If I do
PROMPT="$(parse_git_branch)"
It seems to work, but in fact it's running the command when I set the prompt, which is not the point.
