Re: surrounding a word with tag with a dynamic attribute

Also,

Can someone offer the modified version of that which would permit specifying the desired single tag-string (i.e. 'em') as a parameter for the function call, instead of the open-ended user entry of a string?

I visualize doing something like   ':TagSelection em' for the action to be applied without further interaction.  Is that possible?

Thank you in advance for anyone's contributing that modified code.

Hi David,

Your posting of the tip dates quite a while ago.

Any idea if that would still work for vim/gvim 8.1 ?

Is that added to the ~/.vim/vimrc  ?

Finally, is that action triggered by typing the sequence   ':TagSelection'   ?

Thank you,

Eric

I wrote my own function specifically to wrap XML tags around some
highlighted text. If the text is part of a line I wrap it inline. If
the text (visually selected) spans multiple lines, then I add the tags
on new lines before and after the text.

I also allow you to add attributes and remove those when adding the closing tag.

" Author: David Fishburn
" These mappings and TagSelection function will allow you to place
" an XML tag around either the current word, or the current selected

" If the visual select is on a single line, the tag is wrapped

" over multiple lines, the tag is wrapped around the text
" <this>

" When you are prompted for the tag name, you can enter:
" Tag name? p class="classname" attri="bute"
" The select is wrapped with:
" <p class="classname" attri="bute">
" Your selection
" </p>
" Notice the attributes have been stripped from the closing tag.

" Use nmap, not nnoremap, since we do want to use an existing mapping
nmap ,,, viw,,,

function! TagSelection()
let tag = input("Tag name (include attributes)? ")

if strlen(tag) == 0
return
endif

" Save b register
let saveB = @b

" this will disable it until we have applied our changes
let saveIndent = &indentexpr

let newline = ''
if getline("'>") != getline("'<")
let newline = "\n"
let curl = line("'>")
endif

" Strip off all but the first word in the tag for the end tag

If it is of any use to you.

Enjoy.
