- What was occurred? (as is)
A custom label inherits from "exuberant-ctags", i.e. gets all its langmap definitions. One is supposed to be replaced without modifying the "exuberant-ctags" label.
Apparently, gtags processes the langmap in the way "first wins", as I have to specify the replacement mapping before including the parent. This list is then passed to the ctags parser in the same order. Ctags processes the list in the way "last wins".
As a result, gtags --explain tells me the expected langmap result. Ctags, however, which uses the original langmap, doesn't find any tags in the file.
- What did you expect from it?
Not knowing anything about the gtags internals or the ctags parser in particular, I'd suggest that gtags invokes ctags with the option "--language-force", passing as an argument the language that gtags thought was the correct one.
Thanks
