Compute «${#BUFFER}» just once. I haven't measured the effect of this, but
it might just avoid a strlen() every time around the loop, which could add
up for large ${BUFFER}s.
See issue #295.
zsh-syntax-highlighting / highlighters / brackets
This is the brackets highlighter, that highlights brackets and parentheses, and
matches them.
How to tweak it
This highlighter defines the following styles:
bracket-error- unmatched bracketsbracket-level-N- brackets with nest level Ncursor-matchingbracket- the matching bracket, if cursor is on a bracket
To override one of those styles, change its entry in ZSH_HIGHLIGHT_STYLES,
for example in ~/.zshrc:
# To define styles for nested brackets up to level 4
ZSH_HIGHLIGHT_STYLES[bracket-level-1]='fg=blue,bold'
ZSH_HIGHLIGHT_STYLES[bracket-level-2]='fg=red,bold'
ZSH_HIGHLIGHT_STYLES[bracket-level-3]='fg=yellow,bold'
ZSH_HIGHLIGHT_STYLES[bracket-level-4]='fg=magenta,bold'
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.
