What is mcs?

mcs is a small tool to synchronize multiple – file or HTTP based – Monticello repositories. Synchronization in this case is nothing more than copying missing versions from one repository to another.

How to use mcs?

mcs is a runnable python package with an easy syntax: It currently supports two sub-commands (copy and list). Examples:

mcs list http://www.squeaksource.com/AST/ lists versions in the online SqueakSource repository. mcs knows some common SqueakSource installations in the world (as the Squeak Installer class does), so you could also write mcs list ss:AST.

mcs copy ss:AST /tmp/ast_repo copies all versions from the online SqueakSource repository to the local ast_repo folder, only copying versions that are not already in the local repository.

The following repository types are supported:

• HTTP and HTTPS repositories: Use the standard URL syntax for those repositories. You can specify your username and password using the form http://username:password@hostname/path/. Be aware that most SqueakSource installations require the trailing slash.
• Known HTTP repositories: Use the syntax alias:project where alias is one of lukas, squeak, squeakfoundation, ss, wiresong and hpi.
• Local repositories: mcs will try to open every URL not matching one of the pattern before as file system paths. You can specify absolute and relative paths, Windows UNC Paths should also work.

If you need credentials to perform actions, you can provide them

• for HTTP repositories in the known way, i.e. http://user:pass@host/path/
• for shortcuts using the syntax shortcut:user:pass@path.

Run mcs help for more information and optional switches.

Known Issues

• (Windows only) If you use the mcs.exe provided through distribute, you might have problems using the pattern switch. Those occur because the .exe does the globbing itself, i.e. expands arguments with stars (*) if it finds matching files. I think, this is a bug in distribute or rather its console_scripts implementation.

Requirements

mcs uses httplib2 for HTTP repositories.
