Question about tagfield handling in tagbar
Hi,
I'm a co-developer of universal ctags(https://ctags.io). I would like to know the way how tagbar handles "tagfield" in a tags file. As explained in http://ctags.sourceforge.net/FORMAT, "name" part of tagfield is specified as
6. Proposal
-----------
Use a comment after the {tagaddress} field. The format would be:
{tagname}<Tab>{tagfile}<Tab>{tagaddress}[;"<Tab>{tagfield}..]
...
{tagaddress} Any Ex command. When executed, it behaves like 'magic' was
not set. It may be restricted to a line number or a search
pattern (Posix).
...
{tagfield} See below.
A tagfield has a name, a colon, and a value: "name:value".
- The name consist only out of alphabetical characters. Upper and lower case
are allowed. Lower case is recommended. Case matters ("kind:" and "Kind:
are different tagfields).
In universal ctags I would like to violate the rule. I would like to introduce a word separator like ' '(space), '-', or '_'. e.g.
-28,6 +28,7 input.diff /^@@ -28,6 +28,7 @@$/;" h modified file:a/main/parsers.h
In this tag file modified file is used as tagfield.
I heard tagbar doens't work if ' '(space) is used as the work separator.
So I'm looking for alternative character. Candidates are _ and -.
Do you have any recommendation?
Or such violation is not acceptable?
Using camel case like modifiedFile can be used but I don't like it. So I would like to use camel case only if tagbar accepts only alphabetical characters.
About this issue ctags developers are discussed at https://github.com/universal-ctags/ctags/pull/503 .
Hey, sorry for the really late reply. In case it is still relevant, at the moment Tagbar uses \w to match field names, so it can deal with _ in them, but not with - or spaces. But I don't really see an issue with allowing both of them, since only tabs and colons are special as separator characters.
