Multiple TernDef calls from within script: jumplist

[davidsu]

we are using requirejs and many times tern jumps into the return of the function ( which is correct since this is where the variable was defined ) but we want to further jump and get to the initial definition of what we were looking for. I've added a piece of code that does just that, based on our codestyle a simple regex may inform us that this is not the place we wanted to see... but we are getting additional stop on our way back with ctrl+o. we would like to ask tern for additional jumps without adding to the jump list.
following the piece of code in my .vimrc ( still need improvement but it's good enough for now )

function! GoToDeclaration()
    let l:pos = getpos('.')
    let l:currFileName = expand('%')
    let l:lineFromCursorPosition = strpart(getline('.'), getpos('.')[2])
    let l:wordUnderCursor = expand('<cword>')
    let l:isFunction = match(l:lineFromCursorPosition , '^\(\w\|\s\)*(') + 1
    silent TernDef
    if join(l:pos) == join(getpos('.'))
        "can't jump to definition with tern, do a search with ag + fzf
        if l:isFunction
            FindNoTestFunction(l:wordUnderCursor)
        else
            call fzf#vim#ag(expand('<cword>'), s:defaultPreview ) 
        endif
        call feedkeys(l:wordUnderCursor)
    else
        let l:newCursorLine = getline('.')
        let l:newCurrFileName = expand('%')
        let l:regex = '^\s*' . l:wordUnderCursor . '\s*\(,\?\|\(:\s*' . l:wordUnderCursor . ',\?\)\)\s*$'
        echom l:regex
        if l:newCurrFileName != l:currFileName && match(l:newCursorLine, '\((\|=\)') < 0 && match(getline('.'), regex ) + 1
            "we are inside a module.exports, maybe we can get to the line where the function is declared
            echom 'the line: ' . getline('.')
            call search(l:wordUnderCursor . '\s*\((\|=\)')
            " note that i changed this function in python to allow `add_jump_position` argument
            py3 tern_lookupDefinition("edit", add_jump_position=False)
        endif
        normal zz
        call CursorPing()
    endif
endfunction
