      Hi! I’m using notepad++ from many years, and I’ve never managed to make function list working with objects an JavaScipt. I’ve combined some code I’ve found around the web and I managed to make it works with both EC6 ‘class’ Syntax and prototype syntax. Of course, It’s not perfect, but I wanted to share this with you.
      Have fun !!

        id         ="javascript_function"

        1. The RegEx (\t|[ ]{2,4}) tries to match a tab, 2 spaces, 3 spaces (!) or 4 spaces.
          To only support “tab/2space/4space” you have to write the RegEx as (\t|\x20{2}|\x20{4}) (allthough not necessary replaced [ ] with \x20).
        2. A <parser> nodes can only contain ONE <classRange>-node.
        3. In [\n\s] the \s makes the \n superfluous as \n is included in \s.

          Thanks for your code, it helped me to finally get the function list working for Javascript classes.

          As a reference for others who find this topic, I got the code to work by following this page of the manual. It referenced this page, which mentions that the file structure for use with Notepad++ v7.9.1 and later should be like this:

          <NotepadPlus><functionList> [your parser code goes here] </functionList></NotepadPlus>

          I don’t know about the points mentioned by MAPJe71 but it works for me. :-)

            @netoale-netoale This worked fairly well, thank you, but was picking up a few keywords i didn’t want [if, for, switch, …etc]. If you’re having a similar issue, i got Claude to improve it like so:

            <parser
       displayName="JavaScript"
       id         ="javascript_function"
       commentExpr="(?s:/\*.*?\*/)|(?m-s://.*?$)"
