Syntax plugin for Vim9. Work in progress.

Configuration

The highlighting can be controlled via keys in the dictionary g:vim9_syntax:

• builtin_functions controls whether builtin functions are highlighted (true by default)
• data_types controls whether Vim9 data types in declarations are highlighted (true by default)
• user_types controls whether user types are highlighted (:help :type; false by default)
• errors controls whether some possible mistakes are highlighted
• fenced_languages is a list of languages which should be highlighted with their own syntax when included inside fenced codeblocks (empty list by default)

g:vim9_syntax.errors is a nested dictionary containing these keys:

• event_wrong_case controls whether names of events in autocmds are highlighted as errors, if they don't have the same case as in the help (false by default)
• octal_missing_o_prefix controls whether an octal number prefixed with 0 instead of 0o is highlighted as an error (false by default)
• range_missing_space controls whether no space between a line specifier and a command is highlighted as an error (false by default)
• range_missing_specifier controls whether an implicit line specifier is highlighted as an error (false by default)
• strict_whitespace controls whether missing/superfluous whitespace is highlighted as an error (true by default)

Example of configuration:

g:vim9_syntax = {
   builtin_functions: true,
   data_types: false,
   user_types: false,
   fenced_languages: ['lua', 'python'],
   errors: {
       event_wrong_case: false,
       octal_missing_o_prefix: false,
       range_missing_space: false,
       range_missing_specifier: false,
       strict_whitespace: true,
   }
}
