sccs-fast-export - SCCS to git converter using git-fast-import
This software is licensed under the ISC license and was written by Eric Krohn krohn-git@ekrohn.com. A few ideas were borrowed from rcs-fast-export.rb, though sccs-fast-export is written in Perl.
Using sccs-fast-export is quite simple for individual SCCS files or a whole directory (repository) of SCCS files:
mkdir repo-git # or whatever
cd repo-git
git init
sccs-fast-export <your-sccs-file> | git fast-import
As SCCS files record only a username for each delta, a username to author
mapping file can be given to sccs-fast-export. The file is specified using the
--authors-file (or -A) option. The file should contain lines of the
form "username=Author Info". The example authors.map below will
translate "thatuser" to "That User <thatuser@example.com>".
# Start of authors.map --
thatuser=That User <thatuser@example.com>
# End of authors.map --
SCCS does not have branch naming per se, but it does have branch deltas. For each terminal branch delta x.y.z.w, sccs-fast-export marks the branch x.y.z.
sccs-fast-export reads an SCCS file to parse the delta table, runs sccs get
to read the delta contents, and outputs each delta as a separate commit.
It does a little bookkeeping to keep track of which deltas are terminal.
sccs-fast-export could run sccs prt or prs to get the delta table, but
it would be slightly ambiguous to parse, so we parse the s.file itself.
