Why the echo result of $vcs_info_msg_0_ contains strange characters in zsh?
This is my PROMPT configuration in zsh:
PROMPT=$'
%{$purple%}%n%{$reset_color%} at %{$orange%}%m%{$reset_color%} in %{$limegreen%}%~%{$reset_color%} $vcs_info_msg_0_
$ '
And this is how my zsh displays
At first I just want to get the master** string for other use, then I searched for how zsh got it, and found that the message was generated by zsh's vcs_info package, and was stored in $vcs_info_msg_0_, but as the screenshot shows, the echo result of that variable was very strange. Why did this happen, and how can I just get the git information (master** with color) of a repository folder?
Solution
That's because the variable is only to be used in prompts, nowhere else. The strange things you see are special control sequences that are interpreted by ZSH when rendering the prompt.
