Ive been working on getting tortoisemerge working as the difftool option in Git with my .gitconfig file currently showing :
[diff]
tool = tortoise
[difftool "tortoise"]
cmd = tortoisemerge.exe -mine:$LOCAL -base:$REMOTE
[difftool]
prompt = false
According to tortoise merge docs the 'mine' command states which file will be shown on the right, in a two way diff.
My question is, what do the LOCAL and REMOTE variables as provided by GIT actually point 开发者_Go百科to? The documentation is a little vague stating that
LOCAL is set to the name of the temporary file containing the contents of the diff pre-image and REMOTE is set to the name of the temporary file containing the contents of the diff post-image.
The problem arises when I modify a file, and then enter 'git difftool' tortoisemerge is started with the working directory file on the LEFT and not the right as I assume. I know I can merely switch the 'mine' and 'local' commands but I was trying to figure out what the local/remote points to and the best way to resolve this issue
there are 4 components to this (note that before this step, you would have already done a local-checkin.)
- The local-checkin that your git tree has: LOCAL
- The head of the remote repository (that is going to be merged): REMOTE
- common ancestor to both LOCAL and REMOTE: BASE
- The file that will be written as a result: MERGED.
I think that means that $LOCAL
is always the a/whatever
in the diff output, while $REMOTE
is the b/whatever
. In other words, if you do:
git difftool master experiment -- Makefile
$LOCAL
will be a temporary file showing the the state of Makefile
in the master
branch, while $REMOTE
will be a temporary file showing its state in the experiment
branch.
If you just run:
git difftool
... that shows you the difference between the index and your working tree, so for each file with differences, $LOCAL
will be a temporary file that's the same as the version of the file in the index, while the $REMOTE
will be the version of the file in your working tree.
I am using TortoiseSvn for merge and diff and is working as expected. While in diff, it shows my working copy on the right. My .gitconfig with TortoiseSvn is as follows
[diff]
tool = tortoise
[merge]
tool = tortoise
[mergetool "tortoise"]
cmd = TortoiseMerge.exe -base:\"$BASE\" -mine:\"$LOCAL\" -theirs:\"$REMOTE\" -merged:\"$MERGED\"
[difftool "tortoise"]
cmd = tortoisemerge.exe -mine:\"$REMOTE\" -base:\"$LOCAL\"
