Artemis
=======

Artemis is a lightweight distributed issue tracking extension for Mercurial_.

Individual issues are stored in directories in an ``.issues`` subdirectory
(overridable in a config file).  Each one is a Maildir_ and each one is assumed
to have a single root message.  Various properties of an issue are stored in the
headers of that message.

.. _Mercurial:      http://www.selenic.com/mercurial/
.. _Maildir:        http://en.wikipedia.org/wiki/Maildir

One can obtain Artemis by cloning its repository:

.. parsed-literal::

    hg clone http://hg.mrzv.org/Artemis/

or downloading the entire `repository as a tarball`_.

.. _`repository as a tarball`:  http://hg.mrzv.org/Artemis/archive/tip.tar.gz


Setup
-----

In the ``[extensions]`` section of your ``~/.hgrc`` add::
    
    artemis = /path/to/artemis.py

Optionally, provide a section ``[artemis]``, and specify an alternative path for
the issues subdirectory (instead of the default ``.issues``)::

    [artemis]
    issues = _issues


Example
-------

Create an issue::

    # hg iadd
    ... enter some text in an editor ...
    Added new issue 907ab57e04502afd 

    # hg ilist
    907ab57e04502afd (  0) [new]: New issue

    # hg ishow 907
    ======================================================================
    From: ...
    Date: ...
    Subject: New issue
    State: new

    Detailed description.
    
    ----------------------------------------------------------------------

Add a comment to the issue::
    
    # hg iadd 907
    ... enter the comment text
    ======================================================================
    From: ...
    [snip]
    Detailed description.
    
    ----------------------------------------------------------------------
    Comments:
      1: [dmitriy] Some comment
    ----------------------------------------------------------------------

And a comment to the comment::

    # hg iadd 907 1
    ... enter the comment text ...
    ======================================================================
    From: ...
    [snip]
    Detailed description.
    
    ----------------------------------------------------------------------
    Comments:
      1: [dmitriy] Some comment
        2: [dmitriy] Comment on a comment
    ----------------------------------------------------------------------

Close the issue::

    # hg iadd 907 -p state=resolved -p resolution=fixed -n
    ======================================================================
    From: ...
    [snip]
    Detailed description.
    
    ----------------------------------------------------------------------
    Comments:
      1: [dmitriy] Some comment
        2: [dmitriy] Comment on a comment
      3: [dmitriy] changed properties (state=resolved, resolution=fixed)
    ----------------------------------------------------------------------

No more new issues, and one resolved issue::

    # hg ilist
    # hg ilist -a
    907ab57e04502afd (  3) [resolved=fixed]: New issue

The fact that issues are Maildirs, allows one to look at them in, for example,
``mutt`` with predictable results::

    mutt -Rf .issues/907ab57e04502afd

Commands
--------

`iadd` ``[ID] [COMMENT]``
    Add an issue, or a comment to an existing issue or comment. The comment is
    recorded as a reply to the particular message. `iadd` is the only command
    that changes the state of the repository (by adding the new issue files to
    the list of tracked files or updating some of them), however, it does not
    perform an actual commit.

    `-p`, `--property`
        update a property of the issue ``ID``, e.g. ``-p state=resolved -p resolution=fixed``

    `-a`, `--attach`
        attach a file to the message, e.g. ``-a filename1 -a filename2``

    `-n`, `--no-property-comment`
        do not launch an editor to record a comment (useful if only changing
        properties)

    `-m`, `--message`
        use ``text`` as an issue subject


`ilist`
    List issues.

    `-a`, `--all`
        list all issues (not just the `new` ones)

    `-p`, `--property`
        list issues with specific property values, e.g. 
        ``-p state=resolved -p category=documentation``;
        if no property value is provided (e.g. ``-p category``), lists all
        possible values for that property (among the issues that satisfy the
        rest of the criteria)

    `-d`, `--date`
        restrict to issues matching the given date, e.g. ``-d ">1/1/2008"``

    `-f`, `--filter`
        restrict to a predefined filter, see Filters_ below
   

`ishow` ``[ID] [COMMENT]``
    Show an issue or a comment.

    `-a`, `--all`
        list all comments to an issue (i.e. not just a single message, and a
        thread of subjects of its replies)

    `-s`, `--skip`
        in the output skip lines of the messages starting with the given
        substring, defaults to ``>``

    `-x`, `--extract`
        extract attachments (given their numbers)

    `--mutt`
        use ``mutt`` to show issue


Filters
-------

Artemis scans all files of the form ``.issues/.filter*``, and processes them as
config files. Section names become filter names, and the individual settings
become properties. For example the following::

    [olddoc]
    category=documentation
    state=resolved

placed in a file ``.issues/.filter`` creates a filter `olddoc` which can be
invoked with the `ilist` command::

    hg ilist -f olddoc
