Backing up abbrev_defs?

Backing up abbrev_defs?

[Sharon Kimble]

[-- Attachment #1: Type: text/plain, Size: 838 bytes --]

Can some kind soul help me out please?

I want to backup my abbrev_defs file exactly the same as everything else is backed up, i.e. when there is a change to it, a backup is triggered to save it in ~/.emacs.d/backups. Although the position is slightly complicated as its not normally open in any buffer, so the backup would presumably have to be triggered on the source files changing.

I've googled but haven't found any instances of it being backed up, so there isn't anything seemingly available for me to hack from or with. So can some kind soul help with some working code, or guidance to a non-programmer to achieve this please?

Thanks
Sharon.

I don't understand the question.  Are you saying that when you save
your abbrevs, Emacs doesn't create a backup file for abbrev_defs, as
it does for any other file you save?

No! No backup created from it at all! Which I found was rather strange, hence my request.

Thanks
Sharon.

What command(s) did you invoke to save your abbrevs?

C-c C-c

Thanks

I suggest to submit a bug report using "M-x report-emacs-bug".  I
clearly see on my machine a backup file for abbrev_defs, but upon
reviewing the code in abbrevs.el I don't think that backup file was
created by Emacs.  So this sounds like a missing feature.

Meanwhile, you could work around by editing the abbrev_defs file
directly, as opposed to saving it with C-c C-c.
