mercurial user: how do you rebase or merge using emacs?

[Uwe Brauer]

Hi

I use either vc-dir or the ahg package. Both are nice for showing the
graph and commiting, even for interactive commiting, which I do a lot
lately.

However, merging and rebasing I have to do via the command line and then
although emacs pops up, emacs is just in text mode but not in
vc-hg-log-edit-mode so I don't have the usual emacs support.


I am not sure how many emacs users are on this list, but if they are I'd
love to hear about their workflow.


I also tried monky a bit, but it is not very intuitive at least not for me.

I don't thin VC supports rebasing.  But merging is supported: see
vc-merge (a.k.a. "C-x v m" in a vc-dir buffer).

Well yes and no (at least for hg).
Steps:

    1. vc-merge

    2. I am asked for a version to merge.

    3. I obtain 
Running "merge 5"...
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
(branch merge, don't forget to commit)

(5 because hg has also local rev numbers beside HASHES)

But the commit that is needed, cannot be done my vc, at least I am unable, vc-dir  gives.

VC backend : Hg

Branch     : default
Commit     : 1 modified (merge)
Update     : (current)
Phases     : 7 draft

                         ./
    edited               test.org

But when I select, as usual the edit file and run vc-next-action I obtain 


Running "commit -m Merge

 test.org"...
abort: cannot partially commit a merge (do not specify files or patterns)

Well so I repeat the operation without selecting a file, I obtain

This could be some cockpit error, but in any case, suggest to report
the recipe with the problem to the bug tracker, and then the VC
experts will figure out what's wrong.

I repeated the steps, after the merge the vc-dir buffer looks like this 

VC backend : Hg
Working dir: ~/HGTest/1-Merge-Test/
Parent     : 7:623174bf7b0e tip
           :  Now we are ready to merge
Parent     : 5:1e5a4938edf0 
           :  Six
Branch     : default
Commit     : 1 modified (merge)
Update     : (current)
Phases     : 8 draft

                         ./
    edited               test.org


If the cursor is *not* on the line 
    edited               test.org

Then everything is ok, however if the cursor is on that line an error
pops up, also the file has *not* been marked.

I find this counterintuitive to say the least

I am aware that this won't help you (at least short-term), but I had
a similar problem (hg support in Emacs in general) and solved it by
moving to Git.

Actually not. I cannot deal with git, the distinction between local and
remote drives me crazy. It has no named branches, no local rev numbers,
and some of the commands are cryptic to say the least (yes I know there
is the git-hg Rosetta).
