Formats the path to the current working directory to be used by prompts.

Use the following zstyle to truncate the path to the git root when in a git repo:

zstyle ':zim:prompt-pwd' git-root yes

To truncate the number of trailing path components, use the following zstyle with a positive value:

zstyle ':zim:prompt-pwd:tail' length <value>

To customize the maximum number of characters per path component, use:

zstyle ':zim:prompt-pwd:fish-style' dir-length <value>

Setting the value to 0 will disable shortening entirely, which is the default behavior.

The default path separator is / and it can be customized using:

zstyle ':zim:prompt-pwd:separator' format '<format>'

You can include prompt expansion escape sequences in your custom separator format.

Add a call to the prompt-pwd function in your prompt code where you want the current working directory to be displayed. Here's an example:

setopt nopromptbang prompt{cr,percent,sp,subst}

zstyle ':zim:prompt-pwd' git-root yes
zstyle ':zim:prompt-pwd:fish-style' dir-length 1
zstyle ':zim:prompt-pwd:separator' format '❯'

PS1='$(prompt-pwd)❯ '

If you want to use prompt-pwd inside a function, call it passing the variable name you want it to set. A dummy example:

prompt-pwd-len() {
  local current_dir
  prompt-pwd current_dir
  print ${#current_dir}
}
