NAME

subatom - produce an atom feed from subversion commits

SYNOPSIS

  subatom [-m max] [-o output] [-v viewcvs] REPOSITORY_URL [path ...]
  subatom -c config_file

DESCRIPTION

subatom is a small script to produce an Atom feed from subversion commits. You can use this with a feed reader to see new commits to your repository.

The first argument is the URL for your subversion repository. The remaining arguments are paths within the repository for which you would like commit messages. If you don't specify any, it will default to the entire repository.

The -m flag states how many entries you would like in the feed. The default is 30.

If you pass a filename using the -o flag, the output will be written there instead of STDOUT. If the filename already exists then the timestamp will be checked and the new feed will only be written if it actually contains any newer entries. If you will be serving the feed file using a web server, then doing this enables If-Modified-Since to work correctly (ie: feed readers will only download the file if it has actually changed).

You can pass an URL using the -v flag, and subatom will create a link for each commit by appending the revision number to the URL. For example a viewcvs URL might look like this (on the command line).

    http://example.com/viewcvs/svn/?view=rev&rev=

If the URL has question marks or ampersands, don't forget to quote it on the command line. If you don't, the shell will interpret them and probably give some odd looking errors.

If you don't pass in a URL, a link will be automatically made to the first file that changed in this commit.

If you pass an URL using the -s flag, it will be used as the self link for the feed. Use this if you would like to avoid warnings from the feed validator.

CONFIG FILE

In order to avoid wrapper scripts calling subatom with lots of parameters, you can also specify a config file. The format of the file consists of lines containing key-value pairs separated by whitespace. A blank line introduces a new stanza. You can generate multiple feeds by specifying several stanzas.

The following keywords are recognized.

max_entries

How many entries should be in the feed? Defaults to 30.

output_file

Where should the feed be written to? Must be specified.

repos_url

The path to the root of the repository. Must be specified.

NB: subatom likes to have the trailing slash removed, if you get any complaints, try taking it off.

path

Specifies a directory in the repository to monitor commit messages for. Defaults to '/'.

self_url

Specifies the URL of the feed that will be produced. No default.

viewcvs_url

Specifies an URL prefix which will have the revision number appended to produce the link for each commit. For example, if you have a trac setup, use something like this:

  viewcvs_url http://dev.rubyonrails.org/changeset/
feed_title

Specify the title for the feed as a whole. Defaults to "Recent commits to $repos_url".

EXAMPLE

    output_file /www/svn.atom
    path        /trunk
    repos_url   http://svn.collab.net/repos/svn
    self_url    http://localhost/svn.atom
    viewcvs_url http://svn.collab.net/viewvc/svn?view=rev&revision=
    feed_title  Subversion Changes

    output_file /www/rails.atom
    path        /trunk
    repos_url   http://dev.rubyonrails.org/svn/rails
    self_url    http://localhost/rails.atom
    viewcvs_url http://dev.rubyonrails.org/changeset/
