I have these lines in my .vimrc
if has("gui_macvim")
source ~/.vim/vimrc/mygfuncs.vim
endif
In the mygfuncs file are some functions that set the `guitablabel` and
`guitabtooltip` based on two custom functions. The file is being
sourced (because the functions are defined), but the lines that set
those variables using those functions aren't working:
set guitabtooltip=%{GuiTabToolTip()}
set guitablabel=%{GuiTabLabel()}
At this point, the variables are set properly, because if I
:set guitabtooltip
Vim responds with
guitabtooltip=%{GuiTabToolTip()}
But it isn't actually being applied.
**But** if I then `:so ~/.vimrc`, the tab label and tooltips *are* applied.
What is going on here?

The way to set an option from a value returned by a function is:
let &guitabltooltip=GuiTabToolTip()
if you want to set local value (like setlocal does) you could use:
let &l:guitabtooltip=GuiTabToolTip()
You can read about it in ":help :let-&". You can also use the short
name of an option. &guitabtooltip is just a VimL variable. There is
also &g:guitabtooltip which will work like using the :setglobal command.
Best,
Marcin
No, :set guitablabel=%{GuiTabLabel()} is actually the example given
under :help 'guitablabel' so that the function is calculated every time
Vim tries to display the GUI tabs. Using :let &guitablabel =
GuiTabLabel() would calculate the function just once, when setting the
option.
For GUI tabs to be displayed, you need the e flag in 'guioptions'. Also,
the value of 'showtabline' is relevant:
0 Never
1 (default) Only if there are two or more tab pages
2 Always
If 'showtabline' is nonzero and 'guioptions' does not contain e you'll
get text-style tabs as defined by the 'tabline' option, even in GUI mode.
If these options are set correctly and you still don't see the tabs,
then another possibility is that Vim would set 'guitablabel' and
'guitabtooltip' to some default (or empty) value at GUI startup. To
counteract this, you can set them at the GUIEnter autocommand event:
if has('gui') && has('autocmd') && has('windows')
au GUIEnter * set gtl=%{GuiTabLabel()} gtt=%{GuiTabTooltip()}
endif
Best regards,
Tony.
