#+TITLE: Shackle Shell

A shell intended for restricted access on a version control repo server.

This is intended as a replacement for [[https://git-scm.com/docs/git-shell][Git Shell]], but with the additional
commands I want to create new repos, rearrange things, etc built
in.

It will also limit access to only git repos within the file hierarchy I use.

Additionally, this may support passthrough for other version control system like
Pijul.

* Roadmap

** MVP

- [X] interactive command prompt
- [X] non-interactive commands can be run with -c
- [X] exit command
- [X] git init of private repo
- [X] responds to unknown commands
- [X] Isolation of workdir between tests
- [X] git fetch with git upload-pack
- [X] git push with git receive-pack
- [X] proper shell argument lexing, with quote stuff
- [X] history (only within same session)
- [X] don't quit interactive shell sessions if there's an error
- [X] help command
- [X] restrict repos to only acceptable paths
  - [X] clone / pull
  - [X] push
- [X] git init of shared repos
  - [X] create the shared repo in the right place
  - [X] use the right file permissions and config
  - [X] don't allow this to be a group the user isn't in
  - [X] allow pull and push from shared repos
- [X] listing of repos
- [X] set repo descriptions
  - [X] init new repo
  - [X] change an existing repo
- [X] Change ~git-init~ name to just be ~init~. Later, the ~git~ part will be an
  option which defaults to git.
