I have currently set up my ZSH highlighting like this:
ZSH_HIGHLIGHT_HIGHLIGHTERS=(main brackets pattern line)
typeset -A ZSH_HIGHLIGHT_STYLES # For main-highlighter
ZSH_HIGHLIGHT_STYLES[command]='fg=blue'
ZSH_HIGHLIGHT_STYLES[function]='fg=green'
ZSH_HIGHLIGHT_STYLES[builtin]='fg=red'
ZSH_HIGHLIGHT_STYLES[unknown]='fg=green,bold'
ZSH_HIGHLIGHT_STYLES[arg0]='fg=white'
I wanted to add a directive, so that a command word, which is not a valid command (i.e. not in the PATH, nor a function or alias; i.e. a word w, for which type w
would print w not found) is shown in a different colour, so that I can already find typing errors while typing the comman line.
Example: If I want to type gawk
, but start typing the command
gwk ...
instead (and gwk is not a valid command in my environment), I would like to see it a different colour, so that I am alerted of the typing mistake early.
I first thought that the style named arg0 would handle this, but obviously it does not.
Is this possible to achieve, and which highlight style would I have to use for this?
