opengrok does't jump with function name with prefix "__" in C language

[cheneydeng]

hi guys,
I'm using OpenGrok to read one project which written with C language,everything is perfect except the function name with "__" as prefix will not jump to the definition when clicked.I read the html code and find that the marker has no "name" item with such functions.How can i fix it quickly as I'm really rely on OpenGrok.Thanks as advance.

What ctags implementation (+version) do you use ?

[cheneydeng]

@vladak This is my ctags version:

Exuberant Ctags 5.8, Copyright (C) 1996-2009 Darren Hiebert Compiled: Sep 13 2015, 03:28:50 Addresses: <dhiebert@users.sourceforge.net>, http://ctags.sourceforge.net Optional compiled features: +wildcards, +regex

and OpenGrok version ?

One thing you can try is to replace Exuberant ctags with Universal ctags.

Also, could you try to isolate the issue by shortening the file to smallest possible size where the problem still occurs ?

0.13-RC5
main.c.txt
Tried with both ctags and problem still occurs

[tulinkry]

The problem is here: JFlexXref.java#L577-L587. We should move to html5.

Quick fix is to change the regexp there so it can start with _ and rebuild OpenGrok.

@tulinkry the modification works.thanks so much

[vladak]

Still needs to be fixed in master ?

I'd like to fix this in the next release. The quick fix proposed by @tulinkry still works, although that piece of regex has been moved to JFlexXrefUtils.java.

Since it's called a quick fix I assume there's a more proper way to do it? Can someone give me a hint and I'm happy to do a PR.

I have a queued-up patch, "Use HTML5 DOCTYPE, as XHTML was not at all conforming anyway" (9ebda741e), that also integrated @tulinkry 's advice w.r.t. the name matching.
