Library to read, manipulate and write RCS files.

Project description

EditRCS is a library to with functions to read RCS files into Python classes Rcs and RcsDelta, and to manipulate them and write them to a new RCS file.

It is intended to be used to manipulate RCS files in ways that the RCS tools don’t support, but it requires some knowledge of how RCS files work rather than being a polished command-line tool.

See rcsfile(5) for RCS file format definition.

Example scripts in the examples directory include:

checkout_start: print the earliest version of a RCS file to standard output.

rcs_join: produce an RCS file with the history of one file followed by that of a second file.

rename_user: replace an old user name with a new one for each revision checked in by that user.

pivot_branch: given a branch head and a first-level branch head off that, swap the sub-branch and the main branch.

Limitations: I’m going with the 5.9.2 version of the manpage, and ignoring the newphrase in the earlier (e.g. 5.6) specifications for now. It is written to be simple rather than optimised for speed or space.


To install as a Python module run:

python -m pip install /path/to/editrcs
