I am trying to extend ctags ( Exuberant Ctags 5.8 MacOSX ) with a custom language, however the tags file is always empty for the custom language. In order to track down the issue. I used the example from the documentation.
I have the following .ctags in ~:
--langdef=swine
--langmap=swine:.swn
--regex-swine=/^def[ \t]*([a-zA-Z0-9_]+)/\1/d,definition/
When I run ctags --list-kinds I see:
...
swine
d definition
I have a file test.swn:
def hehll
When I run ctags -L test.swn I see:
ctags: Warning: cannot open source file "def hehll" : No such file or directory
and the tags file generated looks like this:
!_TAG_FILE_FORMAT 2 /extended format; --format=1 will not append ;" to lines/
!_TAG_FILE_SORTED 1 /0=unsorted, 1=sorted, 2=foldcase/
!_TAG_PROGRAM_AUTHOR Darren Hiebert /[email protected]/
!_TAG_PROGRAM_NAME Exuberant Ctags //
!_TAG_PROGRAM_URL http://ctags.sourceforge.net /official site/
!_TAG_PROGRAM_VERSION 5.8 //
With other languages the tags file is filled as expected. Only with this custom extension it is empty.
I am not sure what I else I need to do to make ctags produce tags for the custom language.
Doh! Have to run:
ctags test.swn
instead of
ctags -L test.swn
