sync-all: operations over all GHC repositories at once
A GHC tree consists of multiple repositories. The sync-all Perl script lets you operate over them all at once.
The full documentation for sync-all is found by using the --help option:
$ ./sync-all --help
Pulling new patches
If you have an existing tree, here is how to pull new patches into all repositories.
$ ./sync-all pull $ ./sync-all get
The second step is required in the event that new packages or repositories have been added to GHC.
See Building/Rebuilding for how to update your build after pulling patches.
You can also pull patches from another tree, by registering the other tree as a remote, and giving it a name (here anotherghc):
$ ./sync-all -r /another/ghc remote add anotherghc $ ./sync-all pull anotherghc
where /another/ghc is a path to another local GHC repository. You can specify a remote repository here too, e.g. -r http://darcs.haskell.org/ghc-7.2 (remember to omit the final "ghc.git" when using a remote repo).
The sync-all command is useful for finding out what patches you have relative to another repository:
$ ./sync-all fetch anotherghc $ ./sync-all new anotherghc
this tells you which patches there are in your local repository tree relative to the tree over in /another/ghc.
