I would like to make simple utility that opens tag under cursor in popup window introduced in recent vim version. Assuming I get word under cursor with command let l:word = expand("<cword>"), how would I find if tag with that name exists, in which file and on which line number? I know you can use taglist function, but I don't see line number there.
Thanks, Vjekoslav
taglist() is not bound to know the line number at all. Rather it's a command to locate the tag stored in cmd field.
As a special case, cmd could also contain line number, as number is a valid Ex command too. But that depends on how the tag list was generated.
cmd its not a number? Vim has to evaluate it and then make a jump to a location (file + line). I'm interested in how to obtain that information. I quess I could always let the vim handle that part, jump to location, record it, then go back and do my thing. But that seems extra work...

:h taglist() "The ex-command "cmd" can be either an ex search pattern, a line number or a line number followed by a byte number." Is it a problem to do runtime-checking?
cmd. But its a lot more code than I expected :(. I might end up using method I mentioned above. Let the vim do the jump, record, jump back. Use recorded info.

Could use ex command to extract the line number:
system(printf("ex -u NONE %s <<< 'set nomagic | %s=' ", file, cmd))
