m0viefreak 12b879caf7 'main': Use zsh/parameter instead of type -w
If possible, try to use the zsh/parameter module to get
information about a shell words.

This avoids subshells and is a huge speed improvement
on systems such as cygwin.

Note 1:
$commands does not know about PATH_DIRS. So in case
PATH_DIRS is set, 'type -w' is still used if nothing
else matches.

Note 2:
zsh/parameter can't distinguish between 'command' and
'hashed'. Adjusted the test for that case to XFAIL.

The ideal solution would be if whence had an option to
put the result in REPLY instead of printing it to stdout.

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_prefix - prefixes of existing filenames
  • 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.
