Zeus SCM

Closeup of face from statue of ZeusThe last few years have seen much innovation in source code management systems. Personally I find these systems to be needlessly complex, and have long wished for a simpler option. Therefore it is with great pride that I announce a new source code management system: Zeus. Its name comes from a particular event in Greek mythology where Pallas Athena bursts forth, fully grown, from the forehead of Zeus. The guiding principle of Zeus is that source code should appear in its final form, and thus dispenses with such outmoded concepts as file versions and history. Source files simply spring forth from the repository, in all their glory.

Zeus relies on a single environment variable for all of its settings: ${REPO}. This is the central source repository where all files will reside. Zeus supports both local and remote filesystems such as NFS. The Zeus command structure is designed to leverage a developer's familiarity with existing shell commands. For example, checking code out from the repository is deliberately very similar to a copy command:

zeus cp ${REPO}/ client/

Other available Zeus commands include, but are not limited to:

  • zeus ls ${REPO} : list files in the repository
  • zeus ls -l ${REPO} : detailed information about files in the repository
  • zeus echo "note" >> ${REPO}/notes.txt : maintain a feature request list in the repository
  • zeus cat ${REPO}/ : print to the console, without checking it out

Another great thing about Zeus is its simple, straightforward implementation. Any developer can understand its workings, and implement changes to meet their needs.

I hope you enjoy using Zeus as much as I do. Many thanks to Mark Essel for his contribution of ideas.
