zsh-syntax-highlighting / highlighters / main
=============================================
This is the ***main*** highlighter, that highlights:
* Commands
* Options
* Arguments
* Paths
* Strings
How to activate it
------------------
To activate it, add it to `ZSH_HIGHLIGHT_HIGHLIGHTERS`:
ZSH_HIGHLIGHT_HIGHLIGHTERS=( [...] main)
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
* `alias` - aliases
* `suffix-alias` - suffix aliases (requires zsh 5.1.1 or newer)
* `builtin` - shell builtin commands
* `function` - functions
* `command` - commands
* `precommand` - precommands (i.e. exec, builtin, ...)
* `commandseparator` - command separation tokens
* `hashed-command` - hashed commands
* `path` - paths
* `path_prefix` - path prefixes
* `path_approx` - approximated paths
* `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-double-quoted-argument` - dollar double quoted arguments ($foo inside "")
* `back-double-quoted-argument` - back double quoted arguments (\x inside "")
* `assign` - variable assignments
* `default` - parts of the buffer that do not match anything
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 declaring styles is documented in [the `zshzle(1)` manual
page](http://zsh.sourceforge.net/Doc/Release/Zsh-Line-Editor.html#SEC135).
