How to show custom taglist in window like :tag or :ptag

Question

I use taglist() to get a tag list. Then I did some filter, just leave some useful one like this:

let tttlist = taglist("^List$")
"echo ttt
let newtttlist = []
for item in tttlist
   if item['kind'] == 'i' || item['kind'] == 'c'
       call add(newtttlist, item)
   endif
endfor
echo newtttlist

But how to show them like :tag and :ptag in vim?

Answer 1

I see no way to show tags using one of the commands you mentioned so solution is to use :execute with :ptag/:tag on the first item in the list:

execute 'ptag' fnameescape(get(newtttlist, 0, ''))

. More, you don’t need to process tags list after you have found one of the tags:

let tttlist = taglist("^List$")
for item in tttlist
   if item.kind == 'i' || item.kind == 'c'
       execute 'ptag' fnameescape(item.name)
   endif
endfor

. If you mean something else please post here how you are going to make :ptag/:tag show you a list of tags: according to the documentation and observed behavior all they do is jumping to the first match.

Also note: if key of the dictionary contains nothing more then latin letters, digits and underscores then you can access it as dict.key instead of dict['key']. When dictionary is used to pass structured data it is almost always true.
