Option -z/--listsyntaxes was added to git in commit 49c2f5de.  Thanks for the suggestion.

A proposed patch was mailed to the devel list: https://lists.gnu.org/archive/html/nano-devel/2024-05/msg00026.html.

A slightly adjusted version is attached here.

Well, I couldn't resist implementing this, tentatively -- see attached patch.  For now it only has a short option: -z.

In theory it would be nice if nano could list all available syntax names.  But... how often does one need to specify the syntax explicitly?  The average user: never, I guess.

If you need to do this somewhat regularly, why not create a little script?  Something like:

grep -o "^syntax \w\+" /usr/share/nano/*rc | grep -o "\w\+$"

(Syntax names are always all lowercase -- at least those provided by nano itself.)

There is the -Y option for nano:

 -Y <name>      --syntax=<name>         Syntax definition to use for coloring

However, every time I wish to apply a specific syntax to the target file, I cannot remember what's the correct name of it. So I have to keep guessing (Is it capitalized, or is it under another name?), until I finally gave up and grep in the /usr/share/nano/ folder. Do you also consider it helpful if there's an option to list all the defined syntax names?
