Saving a window configuration ?

Saving a window configuration ?

[jonetsu]

Hello,

Is it possible to save in a persistent way a window configuration (like
one saved by doing C-x r w <key> and recalled with C-x r <key>) so that
it can be recalled, with the same files, at a later time ?

Cheers.

Yes, see frameset.el.

If you are looking for interactive commands...

Store window/frame configuration:
`window-configuration-to-register` bound to `C-x r w` by default.
`frameset-to-register` bound to `C-x r f` by default.

Restore window/frame configuration:
`jump-to-register` bound to `C-x r j` by default.

I'm afraid this is only half of it.  From the comments:

If 15 files are opened and the frames are saved, then the files will
need to be re-opened one by one and only after doing that can the
saved positions and sized of the frames be restored to produce what's
expected: restoring emacs like it was when last left, with all the
files and all the frames.  As far as I consider my query, this is
pretty much half-cooked.  What's the use of wanting to be able to
restore emacs like it was with all the frame sizes and positions AND
the files, in a single operation, if all the files have to be manually
opened before ?  If all the files have to be manually opened then might
as well forget about the size and position of the frames and
re-organize them.  

What I would like is to get back to emacs with the 15 files being
displayed just like they were last time.  The corollary to this
mechanism would be that since it can do that, it can thus reload any
other saved "buffers & frames" (B&F for short).  So if I switch from one
project to another I can save the current B&F and then switch to the
other project's B&F in one operation, ready to continue from the exact
same place it was left before. And later on switch back to the previous
project's saved B&F

This sounds like you want to use 'desktop-save'/'desktop-read' in
combination with 'desktop-restore-frames t' (along with specifying a
project directory every time you call those functions)

desktop.el might be overkill though, it saves a lot of state.

Have you tried `desktop.el'?

Although it does not seem to store frame sizes and positions, from the
Wikemacs description.  But it can be used with bookmarks in such a way
as to have several saved desktops to choose from. OTOH, Wikemacs points
to psession.el which do save frame info (eg. last window configuration)
along with buffers.  I will give psession a try.

It does save and restore those, AFAIK.

Yes, if you use Bookmark+.  Just jump to a (desktop)
bookmark to switch to that desktop.

Most definitely, yes.  If Wikemacs says otherwise, it is wrong and
should be corrected.

Wikemacs doesnʼt say it restores frame sizes and positions, so itʼs an
error of omission rather than commission, which Iʼve corrected.
