zsh-syntax-highlighting / highlighters / main

This is the main highlighter, that highlights:

  • Commands
  • Options
  • Arguments
  • Paths
  • Strings

This highlighter is active by default.

How to tweak it

This highlighter defines the following styles:

  • unknown-token - unknown tokens / errors
  • reserved-word - shell reserved words (if, for)
  • alias - aliases
  • suffix-alias - suffix aliases (requires zsh 5.1.1 or newer)
  • builtin - shell builtin commands (shift, pwd, zstyle)
  • function - function names
  • command - command names
  • precommand - precommand modifiers (e.g., noglob, builtin)
  • commandseparator - command separation tokens (;, &&)
  • hashed-command - hashed commands
  • path - existing filenames
  • path_pathseparator - path separators in filenames (/); if unset, path is used (default)
  • path_prefix - prefixes of existing filenames
  • path_prefix_pathseparator - path separators in prefixes of existing filenames (/); if unset, path_prefix is used (default)
  • globbing - globbing expressions (*.txt)
  • history-expansion - history expansion expressions (!foo and ^foo^bar)
  • single-hyphen-option - single hyphen options (-o)
  • double-hyphen-option - double hyphen options (--option)
  • back-quoted-argument - backquoted expressions (`foo`)
  • single-quoted-argument - single quoted arguments ('foo')
  • double-quoted-argument - double quoted arguments ("foo")
  • dollar-quoted-argument - dollar quoted arguments ($'foo')
  • dollar-double-quoted-argument - parameter expansion inside double quotes ($foo inside "")
  • back-double-quoted-argument - back double quoted arguments (\x inside "")
  • back-dollar-quoted-argument - back dollar quoted arguments (\x inside $'')
  • assign - parameter assignments
  • redirection - redirection operators (<, >, etc)
  • comment - comments, when setopt INTERACTIVE_COMMENTS is in effect (echo # foo)
  • default - everything else

To override one of those styles, change its entry in ZSH_HIGHLIGHT_STYLES, for example in ~/.zshrc:

# Declare the variable
typeset -A ZSH_HIGHLIGHT_STYLES

# To differentiate aliases from other command types
ZSH_HIGHLIGHT_STYLES[alias]='fg=magenta,bold'

# To have paths colored instead of underlined
ZSH_HIGHLIGHT_STYLES[path]='fg=cyan'

# To disable highlighting of globbing expressions
ZSH_HIGHLIGHT_STYLES[globbing]='none'

The syntax for values is the same as the syntax of "types of highlighting" of the zsh builtin $zle_highlight array, which is documented in the zshzle(1) manual page.
