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
• 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 ($'foo')
• dollar-double-quoted-argument - dollar double quoted arguments ($foo inside "")
• back-double-quoted-argument - back double quoted arguments (\x inside "")
• back-dollar-quoted-argument - back dollar quoted arguments (\x inside $'')
• assign - variable assignments
• redirection - redirection operators (<, >, etc)
• comment - interactive comments, when setopt INTERACTIVE_COMMENTS is in effect (echo # foo)
• 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.
