NAME ^

Mail::Summary::Tools - Tools for mailing list summarization.

SYNOPSIS ^

        # create a summary from anything Mail::Box can open.
        # you may also programatically create summary objects and serialize
        # them if you don't have the threads in a standard mail format.

        % mailsum create --dates --posters --clean -i foo.mbox -o summary.yaml


        # edit the text in your editor, if you don't like YAML files

        % mailsum edit --skip --dates --posters --links --archive gmane summary.yaml


        # create pretty outputs

        % mailsum totext --shorten -a google summary.yaml > summary.txt
        % mailsum tohtml --archive google summary.yaml > summary.html

DESCRIPTION ^

This distribution contains numerous classes useful for creating summaries, and an App::Cmd based frontend to those classes.

The main usage is illustrated in the "SYNOPSIS" section.

WORKFLOW ^

In the first step Mail::Summary::Tools takes a mail box of any sort as input, and creates a YAML file for the summary. This file contains a hierarchal structure whereby every thread belongs to exactly one list (cross posts should not be summarized twice), and lots of meta data is also maintained.

This file may be hand edited if you're comfortable with YAML, but typically you use the flat file format, exposed using the edit command to alter the summary texts, hide threads, assign threads to a different list, etc. This can be done either interactively (with Proc::InvokeEditor) or using --save and --load.

If any updating of the summary is necessary you should load all the changes you have using the edit command, and run create --update (it needs a better name). Out of date threads will be marked as long as you use the --dates option (if a thread is summarized and it's end date is extended by the update then it is marked out of date).

When you are done you can emit using totext and tohtml. The default outputs assume that the summary text is written in the markdown language. This translates well to HTML, and looks pretty good as-is in plain text.

SAMPLE FILES ^

YAML Summary

The YAML summary will look something like this:

        ---
        title: Mailing list summary
        extra:
          header:
            - title: A Header Section
          body: fooo bar gorch
          see_also:
            - name: Foo
              uri:  http://www.example.com/
            - name: The Perl Foundation
              uri:  http://www.example.com/
        lists:
          - name: oink
            title: The Oink Mailing list
            threads:
              - message_id: 69d3ac770606131947r55708fc0g139242e5a989ae4e@mail.gmail.com
              posters:
                - email: user@example.com
                  name: User One
                - email: user2@example.com
                  name: User Two
                - email: user3@example.com
                  name: User Three
              subject: 'The Message Subject'
              summary: >-
                Somebody asked whether or not monkeys like to eat cheese, at which
                points the monkey subscribed to the list said that they did not
                like cheese at all where he lives, but that he eats it anyway.

Most fields are optional. The summary bodies should be written in the Markdown language.

Flat File

The flat file format can be generated using the edit command. It's optimized for ease of editing. The basic structure is a list of threads separated by the string \n---\n. Right after the separator is some YAML for meta data, and then an ignored paragraph, and then the summary data:

        The first chunk is ignored, and has instructions

        ---
        message_id: foo@bar.com
        subject: Moose
        hidden: 0 # can be used to omit a thread from the output
        out_of_date: 1 # added by create --update
        thread_uri: http://..../ # hard code a link to a different archive than the default

        # these lines are ignored, and are provided for the summarizers
        # convenience, including random links, posters names, the thread's date
        # range, etc
        <rt://perl/1234>
        Some Guy
        Some Other Guy

        In the thread Titled Moose, Some Guy conjectured on the nature of Some
        Other Guy's mother's profession. Some Other Guy then replied with a witty
        retort. A flamewar ensued.

Text Output

The above summary converted to text (using the totext command) should look like this:

        Mailing list summary

         A Header Section

            fooo bar gorch

         The Oink Mailing List

          The Message Subject <http://xrl.us/moose>

            Somebody asked whether or not monkeys like to eat cheese, at which
            points the monkey subscribed to the list said that they did not
            like cheese at all where he lives, but that he eats it anyway.

         See Also

             * Foo <http://www.example.com>>
             * The Perl Foundation <http://www.example.com/>

The text is emitted in utf8.

Example output can be seen here: http://groups.google.com/group/perl.perl6.announce/msg/7d65491507dda589 (autolinkified by google)

HTML Output

HTML output is also available using the tohtml command.

A real summary is probably a better example, since HTML source is not easily readable: http://pugs.blogs.com/pugs/2006/08/perl_6_mailing__2.html#more

The HTML is ASCII, with all non ascii characters escaped by HTML::Entities.

<divs> are emitted for easy restructuring of the file, and the heading tags are customizable. For example, for use.perl.org Ann emits with --h2 p,b --h3 p,i since h tags are not allowed, and the <divs> are stripped by HTML::Element to keep the size down.
