Hi Leo,
synching with Emacs still needs special care and I am not yet
experienced enough with git to set up something more automatic. So
not, this will not change anything.
Hi Carsten,
git does indeed make it easy to merge changes between Emacs 23 and an
upstream project. I use it for ERC. One strategy is as follows:
- Make a branch called "emacs23" which contains Org exactly as it is
in
Emacs23, but with the same directory structure as your master
branch.
- Make a directory called "scripts" in the emacs23 branch that
contains
two scripts: one to sync changes from Emacs->upstream and one to sync
upstream->Emacs. Both operate by copying files into the proper place
in the Emacs directory hierarchy. Here are some examples -- modify
them to match Org's layout and such.
===== BEGIN file: sync-to-emacs =====
#!/bin/bash
# Load common definitions
. scripts/common.defs

for i in $LISP; do
cp $i $EMACS/lisp/erc
done
for i in $MAN; do
cp $i $EMACS/doc/misc

for i in $IMAGES; do
# Do nothing

cp {} $OLDPWD \;)

cp $EMACS/doc/misc/erc.texi .
rm -f *.elc .cvsignore
git diff --stat

Some scenarios follow.
* Capturing changes from Emacs in the emacs23 branch
- Switch to the emacs23 branch: git checkout emacs23
- Run the relevant sync script: ./scripts/sync-from-emacs
- Use "git add -i" to commit small concise atomic changes until all
changes have been recorded. Optionally use the --author argument to
"git commit" to capture the name of the author of the original
changes.
* Syncing changes from Emacs to upstream Org
- First do the capturing changes into emacs23 step.
- Run "git log" and place its contents into an Emacs buffer.
- git checkout master
- Cherry pick each commit from emacs23 that you want to migrate
upstream by copying its commit ID from the Emacs buffer and doing:
git cherry-pick $COMMIT_ID
* Syncing changes to Emacs
- First do the syncing changes from Emacs step.
- Then switch to the emacs23 branch: git checkout emacs23
- Do a simple "git merge master".
- Resolve any conflicts.
- If new files were added, modify scripts/sync-to-emacs to include
them.
- Run the sync-to-emacs script: ./scripts/sync-to-emacs
- Check in the changes to Emacs using CVS. Or use git, checking in
the
change locally and then doing "git cvsexportcommit" to migrate that
change to CVS. The latter option requires commit access to CVS and
use of the read-only public Emacs git repo at http://git.sv.gnu.org/
(not much point to it, other than to automate contact with CVS as
much as possible :^)
