Is there any way to get vim to save the tab names (assigned via the Tab Name script) and/or a terminal emulator (set up via the Conque Shell script) upon issuing the :mksession [fileName] command?
Observe below (zoom in), I have a working session on the left, and the same session loaded via the vim -S fileName command, on the right. The assigned tab labels revert to absolute paths, ConqueShell terminal is interpreted as a file.
After learning some basic VimScript I just gave up and used Python instead (to cite one example, you can't save global information to a session if it is a list). Here is a solution I found for saving tab names (will post a solution for ConqueShell if I find one)
Put the following in your .vimrc file and use whatever mapping you want to quickly save and load your sessions
"Tokenize it so it has the following form (without spaces)
"Label1 JJ Label2 JJ Label3 JJ Label4
"Or if you prefer use something other than 'JJ' but DO NOT
"use symbols as they could interfere with the shell command
"line
function RecordTabNames()
"Start at the first tab with no tab names assigned
let g:TabNames = ''
tabfirst
"Iterate over all the tabs and determine whether g:TabNames
"needs to be updated
for i in range(1, tabpagenr('$'))
"If tabnames.vim created the variable 't:tab_name', append it
"to g:TabNames, otherwise, append nothing, but the delimiter
if exists('t:tab_name')
let g:TabNames = g:TabNames . t:tab_name . 'JJ'
else
let g:TabNames = g:TabNames . 'JJ'
endif
"iterate to next tab
tabnext
endfor
endfunction
func! MakeFullSession()
call RecordTabNames()
mksession! ~/.vim/sessions/Session.vim
"Call the Pythin script, passing to it as an argument, all the
"tab names. Make sure to put g:TabNames in double quotes, o.w.
"a tab label with spaces will be passed as two separate arguments
execute "!mksession.py '" . g:TabNames . "'"
endfunc
func! LoadFullSession()
source ~/.vim/sessions/Session.vim
endfunc
nnoremap <leader>mks :call MakeFullSession()<CR>
nnoremap <leader>lks :call LoadFullSession()<CR>
Now create the following text file and put it somewhere in your PATH variable (echo $PATH to get it, mine is at /home/user/bin/mksession.py) and make sure to make it executable (chmod 0700 /home/user/bin/mksession.py)
#!/usr/bin/env python
"""This script attempts to fix the Session.vim file by saving the
tab names. The tab names must be passed at the command line,
delimitted by a unique string (in this case 'JJ'). Also, although
spaces are handled, symbols such as '!' can lead to problems.
Steer clear of symbols and file names with 'JJ' in them (Sorry JJ
Abrams, that's what you get for making the worst TV show in history,
you jerk)
