Missing reserved words

[jaopaulolc]

Hi,

I notice that the grammar does not include some reserved words that are part of the language according to the Bash Reference Manual.

This is a list of some with some reserved words that are missing:

("time" "coproc" "type" "trap" "exit" "exec" "continue" "break" "return" "logout" "bye" "true" "false" "test")

My suspicion is that including those would complicate significantly the parser and that my be the reason to leave those out.

However, for fontification and other text editing tasks, it is desirable to identify those.

Is the recommend approach to use a generic query and a regex to find the above reserved words? Something like this:

(command_name ((word) @captured_keyword (#match? @captured_keyword <regex to reserved words>)))

type, test, true, false, and logout are just builtins, while exec, exit, return, break, and continue are "special shell builtins", which cannot be used as function names in --posix mode.

I support adding the select and until keywords and the listed special builtins to the @keyword array since they change control flow so making them stand out would aid reading.

A complete list of keywords and builtins can be generated with compgen -k and compgen -b, respectively.

I added select and until as keywords since they make sense as keywords and they're returned by compgen -k. I don't have an opinion on including exec, exit, return, break, and continue so I won't close the issue.

Also, "bye" is not a reserved word, at least on my Bash 5.2.15.

bye is a zsh builtin in my case

The others are not exposed literals, so no point adding them as keywords unless they're separate statement rules
