Featuregood first issuesyntax:command-word

描述

In f() foo bar, highlight foo as a command word.

This should be simpler than #223, which is about highlighting f: that issue requires (arbitrary far) lookahead, this issue does not.

As discussed in #223:

  • f g h() {} works only when MULTI_FUNC_DEF is set.
  • The syntax function f [g h…] { } also exists.

研究方向
The issue requires modifying the syntax highlighting logic for function definitions in the zsh syntax highlighting project. The relevant code is likely in the main highlighting script that handles keywords and patterns. Look at how function definitions starting with 'f()' are currently tokenized. The existing issue #223 provides discussion on the related lookahead problem. The goal is to highlight the first word after the function name as a command word, without lookahead. Check the MULTI FUNC DEF option handling and the syntax for 'function f g h() {}'.
