ctag database for Go

Question

How to generate tags file for Go source

In mac, I installed exuberant ctags , and tried the below command in source directory

ctags -f gosource.tags -R `pwd` 

But, it doesn't consider *.go files. Do I have to use -h option? But, isn't it only for header files, as per the manual?

Please give me the correct command so that I can use the tags file with vim. I also prefer absolute path so that I can keep the file anywhere

Thanks.

Edit: I assumed current ctags support Go, seeing http://groups.google.com/group/golang-nuts/browse_thread/thread/3a4848db231b02c9.

but, http://ctags.sourceforge.net/languages.html desn't have go listed.

Add the following to ~/.ctags

--langdef=Go --langmap=Go:.go --regex-Go=/func([ \t]+\([^)]+\))?[ \t]+([a-zA-Z0-9_]+)/\2/d,func/ --regex-Go=/var[ \t]+([a-zA-Z_][a-zA-Z0-9_]+)/\1/d,var/ --regex-Go=/type[ \t]+([a-zA-Z_][a-zA-Z0-9_]+)/\1/d,type/
