@UltiMaxKom said in UDL: A folding problem.:
I can’t really tell you why I didn’t use it exactly, though. Well, you don’t really need to know that.
You could tell us, but you’re choosing not to. We don’t need to know it, but it might help us provide a better alternative solution. The fact is, the Lua lexer that comes with Notepad++ would solve the problem you presented; if there is another reason the Lua lexer wouldn’t work for your needs, we might be able to help you better with a workaround centered on the Lua lexer compared to a workaround centered on the UDL lexer. As it is, you are artificially limiting your choices, and being rude about it; I hope that works better for you than I think it will.
I just basically trying to replicate Lua lexer here
The User Defined Language system is not built to fully replicate a custom lexer. There are limitations.
Even in UDL, however, there is some ability to nest. You can set up Folding in code 2 style to have Open: = function if, Middle = empty, Close: = end.
Then, as long as you don’t have extraneous end in your comments that are confusing the UDL lexer, such as changing your comments to say stop instead of end:
function foo() -- The folding will start here.
-- block
end -- The folding will stop here.
function boo() -- The folding will start here.
if condition then
-- block
end -- The folding will stop here.
invalid lua syntax here
end -- The folding stop should be here.
… then both of those fold the way I would expect:
Unfolded:
Fold the inner IF:
Fold the outer functions as well:
If that’s not sufficient, please explain why.
But, since there are limitations in UDL eventually, your choices come down to:
Use a builtin lexer
Use the UDL system, with its limitations
Write a custom lexer
Use one of the above, with PythonScript or LuaScript Plugin-based automation to add extra highlighting via regexes. Given that those scripting languages have access to the same signals that plugins do, you might also be able to edit folding using them as well, but I don’t know how. For examples of adding extra highlighting to a builtin lexer or UDL language, see the example scripts linked below:
script EnhanceAnyBuiltinLexer.py that @Ekopalypse shares in this linked post
script EnhanceUDLLexer.py that @Ekopalypse shares in this linked post
