gvim to show file path in all the tabs (even current one)

Question

By default shows gvim in my tabs: the names of files. They're however shown in a way like this:

• if is in the same as the currently opened tab/buffer => no path shown (only file name)
• otherwise abbreviated path and file name are shown

however when I change the tab this causes tab names to change and brings me quite some confusion.

Any chance to have it constantly going for: abbreviated path and file name are shown?

I've seen following:

:set guitablabel=%!expand(\"\%:t\")

however it goes the other way, so shows only file names on all the tabs (no path at all).

Answer 1

How about this:

:set guitablabel=%!pathshorten(expand(\"\%:p\"))

This uses the :p filename-modifier to get the full absolute path, and then shortens the path via pathshorten() in the way it is usually done in the tab labels.
