ikiwiki/ rcs/ cvs
Available in a git repository branch.
Branch: schmonz/cvs
Author: schmonz

If you really need to, you can use CVS with ikiwiki.

### Usage

1. Install File::chdir, File::ReadBackwards, cvsps (note: probably not cvsps3), and cvsweb or the like.
2. Adjust CVS-related parameters in your setup file.

Consider creating `$HOME/.cvsrc` if you don't have one already; the plugin doesn't need it, but you yourself might. Here's a good general-purpose one:

    cvs -q
    checkout -P
    update -dP
    diff -u
    rdiff -u

### Implementation details

- ikiwiki-makerepo:
  - creates a repository,
  - imports `$SRCDIR` into top-level module `ikiwiki` (vendor tag IKIWIKI, release tag PRE_CVS),
  - configures the post-commit hook in `CVSROOT/loginfo`.

### To do

- Expand test coverage and fix bugs.
- Have `ikiwiki-makerepo` set up NetBSD-like `log_accum` and `commit_prep` scripts that coalesce commits into changesets. Reasons:
  1. Obviates the need to scrape the repo's complete history to determine the last N changesets. (Repositories without such records can fall back on the `cvsps` and `File::ReadBackwards` code.)
  2. Arranges for ikiwiki to be run once per changeset, rather than CVS's once per committed file (!), which is a waste at best and bug-inducing at worst. (Currently, on multi-directory commits, only the first directory's changes get mentioned in recentchanges.)
- Perhaps prevent web edits from attempting to create `.../CVS/foo.mdwn` (and `.../cvs/foo.mdwn` on case-insensitive filesystems); thanks to the CVS metadata directory, the attempt will fail anyway (and much more confusingly) if we don't.
- Do a writeup for details.
