"""static
Create and/or upload a static copy of the repository.
The main goal is sharing Mercurial on servers with only FTP access and
statically served files, while providing the same information as hg
serve and full solutions like bitbucket and gitorious (naturally
without the interactivity).
"""
__plan__ = """
* Create the static-dir in the repo:
- Overview: Readme + commits + template
- Changes: Commit-Log + each commit as changeset/<hex>
- source: a filetree, shown as sourcecode: src/<path> and raw/<path>
- if b is used: a bugtracker: issue/<id>/<name>
- fork-/clone-info for each entry in [paths] with its incoming data (if it has some):
clone/<pathname>/ → commit log + possibly an associated issue in b.
* Usage:
- hg static [--name] [-r] [folder] → parse the static folder for the current revision.
Mimic pull and clone wherever possible: This is a clone to <repo>/static
- hg static --upload <FTP-path> [folder] → update and upload the folder == clone/push
* Idea: hg clone/push ftp://host.tld/path/to/repo → hg static --upload
* Setup a new static repo or update an existing one: hg static --upload ftp://host.tld/path/to/repo
