There are a number of different modes supported, and SVN::Notify is fully subclassable, to add new functionality, and offers L<comprehensive content filtering|SVN::Notify::Filter> to easily modify the format of its messages. By default, A list of all the files affected by the commit will be assembled and listed in a single message. An additional option allows diffs to be calculated for the changes and either appended to the message or added as an attachment. See the C<with_diff> and C<attach_diff> options below. =head1 Usage To use SVN::Notify, simply add a call to F<svnnotify> to your Subversion repository's F<post-commit> script. This script lives in the F<hooks> directory at the root of the repository directory; consult the documentation in F<post-commit.tmpl> for details. Make sure that you specify the complete path to F<svnnotify>, as well as to F<svnlook> and F<sendmail> in the options passed to F<svnnotify> so that everything executes properly. And if you specify any string options, be sure that they are in the encoding specified by the C<--encoding> option, or UTF-8 if you have not specified C<--encoding>. =head2 Windows Usage To get SVN::Notify to work properly in a F<post-commit> script, you must set the following environment variables, as they will likely not be present inside Apache: =over =item PATH=C:\perl\bin =item OS=Windows_NT =item SystemRoot=C:\WINDOWS =back See L<Windows Subversion + Apache + TortoiseSVN + SVN::Notify HOWTO|http://svn.haxx.se/users/archive-2006-05/0593.shtml> for more detailed information on getting SVN::Notify running on Windows. If you have issues with asynchronous execution, try using L<F<HookStart.exe>|http://www.koders.com/csharp/fidE2724F44EF2D47F1C0FE76C538006435FA20051D.aspx> to run F<svnnotify>. =cut # Map the svnlook changed codes to nice labels. my %map = ( U => 'Modified Paths', A => 'Added Paths', D => 'Removed Paths', _ => 'Property Changed', ); my %filters; ############################################################################## =head1 Class Interface =head2 Constructor =head3 new my $notifier = SVN::Notify->new(%params); Constructs and returns a new SVN::Notify object. This object is a handle on the whole process of collecting meta data and content for the commit email and then sending it. As such, it takes a number of parameters to affect that process. Each of these parameters has a corresponding command-line option that can be passed to F<svnnotify>. The options have the same names as these parameters, but any underscores you see here should be replaced with dashes when passed to F<svnnotify>. Most also have a corresponding single-character option. On Perl 5.8 and higher, If you pass parameters to C<new()>, they B<must> be L<decoded into Perl's internal form|Encode/"PERL ENCODING API"> if they have any non-ASCII characters. Supported parameters: =over =item repos_path svnnotify --repos-path "$PATH" svnnotify -p "$PATH" The path to the Subversion repository. The path is passed as the first argument when Subversion executes F<post-commit>. So you can simply pass C<$1> to this parameter if you like. See the documentation in F<post-commit> for details. Required. =item revision svnnotify --revision "$REV" svnnotify -r "$REV" The revision number for the current commit. The revision number is passed as the second argument when Subversion executes F<post-commit>. So you can simply pass C<$2> to this parameter if you like. See the documentation in F<post-commit> for details. Required. =item to svnnotify --to commiters@example.com svnnotify -t commiters@example.com --to managers@example.com The address or addresses to which to send the notification email. Can be used multiple times to specify multiple addresses. This parameter is required unless either C<to_regex_map> or C<to_email_map> is specified. =item to_regex_map svnnotify --to-regex-map translate@example.com=L18N \ -x legal@example.com=License This parameter specifies a hash reference of email addresses to regular expression strings. SVN::Notify will compile the regular expression strings into regular expression objects, and then send notification messages if and only if the name of one or more of the paths affected by a commit matches the regular expression. This is a good way to have a notification email sent to a particular mail address (or comma-delimited list of addresses) only for certain parts of the subversion tree. This parameter is required unless C<to> or C<to_email_map> is specified. The command-line options, C<--to-regex_map> and C<-x>, can be specified any number of times, once for each entry in the hash to be passed to C<new()>. The value passed to the option must be in the form of the key and the value separated by an equal sign. Consult the L<Getopt::Long> documentation for more information. Here's an example complements of Matt Doar of how to use C<to_regex_map> to do per-branch matching: author=`svnlook author $REPOS -r $REV` # The mail regexes should match all the top-level directories /usr/bin/svnnotify --repos-path "$REPOS" --revision "$REV" \ -x eng-bar@example.com,${EXTRAS}="^Bar" \ -x eng-foo@example.com,${EXTRAS}="^trunk/Foo|^branches/Foo|^tags/Foo" \ -x $author@example.com="^users" --subject-cx =item to_email_map svnnotify --to-email-map L18N=translate@example.com \ --to-email-map License=legal@example.com The inverse of C<to_regex_map>: The regular expression is the hash key and the email address or addresses are the value. =item from svnnotify --from somewhere@example.com svnnotify -f elsewhere@example.com The email address to use in the "From" line of the email. If not specified, SVN::Notify will use the username from the commit, as returned by C<svnlook info>. =item user_domain svnnotify --user-domain example.com svnnotify -D example.net A domain name to append to the username for the "From" header of the email. During a Subversion commit, the username returned by C<svnlook info> is usually something like a Unix login name. SVN::Notify will use this username in the email "From" header unless the C<from> parameter is specified. If you wish to have the username take the form of a real email address, specify a domain name and SVN::Notify will append C<\@$domain_name> to the username in order to create a real email address. This can be useful if all of your committers have an email address that corresponds to their username at the domain specified by the C<user_domain> parameter. =item svnlook svnnotify --svnlook /path/to/svnlook svnnotify -l /path/to/svnlook The location of the F<svnlook> executable. If not specified, SVN::Notify will search through the directories in the C<$PATH> environment variable, plus in F</usr/local/bin> and F</usr/sbin>, for an F<svnlook> executable. Specify a full path to F<svnlook> via this option or by setting the C<$SVNLOOK> environment variable if F<svnlook> isn't in your path or to avoid loading L<File::Spec|File::Spec>. It's important to provide a complete path to F<svnlook> because the environment during the execution of F<post-commit> is anemic, with nary a C<$PATH> environment variable to be found. So if F<svnnotify> appears not to be working at all (and Subversion seems loathe to log when it dies!), make sure that you have specified the complete path to a working F<svnlook> executable. =item sendmail svnnotify --sendmail /path/to/sendmail svnnotify -s /path/to/sendmail The location of the F<sendmail> executable. If neither the C<sendmail> nor the C<smtp> parameter is specified, SVN::Notify will search through the directories in the C<$PATH> environment variable, plus in F</usr/local/bin> and F</usr/sbin>, for an F<sendmail> executable. Specify a full path to F<sendmail> via this option or by setting the C<$SENDMAIL> environment variable if F<sendmail> isn't in your path or to avoid loading L<File::Spec|File::Spec>. The same caveats as applied to the location of the F<svnlook> executable apply here. =item set_sender svnnotify --set-sender svnnotify -E Uses the C<-f> option to C<sendmail> to set the envelope sender address of the email to the same address as is used for the "From" header. If you're also using the C<from> option, be sure to make it B<only> an email address. Don't include any other junk in it, like a sender's name. Ignored when using C<smtp>. =item smtp svnnotify --smtp smtp.example.com The address for an SMTP server through which to send the notification email. If unspecified, SVN::Notify will use F<sendmail> to send the message. If F<sendmail> is not installed locally (such as on Windows boxes!), you I<must> specify an SMTP server. =item smtp_tls svnnotify --smtp-tls Use TLS authentication and encrypted channels for connecting with the server. Usually, TLS servers will require user/password authentication. =item smtp_user svnnotify --smtp-user myuser The user name for SMTP authentication. If this option is specified, SVN::Notify will use L<Net::SMTP_auth|Net::SMTP_auth> to send the notification message, and will of course authenticate to the SMTP server. =item smtp_pass svnnotify --smtp-pass mypassword The password for SMTP authentication. Use in parallel with C<smtp_user>. =item smtp_port svnnotify --smtp-port 465 The port for an SMTP server through which to send the notification email. The default port is 25. =item smtp_authtype svnnotify --smtp-authtype authtype Deprecated in SVN::Notify 2.83, where it has become a no-op. The auth type is determined by the contents returned by the SMTP server's response to the C<EHLO> command. See L<Net::SMTP::TLS/TLS and AUTHentication> for details. =item encoding svnnotify --encoding UTF-8 svnnotify -c Big5 The character set typically used on the repository for log messages, file names, and file contents. Used to specify the character set in the email Content-Type headers and, when the C<language> parameter is specified, the C<$LANG> environment variable when launching C<sendmail>. See L</"Character Encoding Support"> for more information. Defaults to "UTF-8". =item charset svnnotify --charset UTF-8 Deprecated. Use C<encoding> instead. =item svn_encoding svnnotify --svn-encoding euc-jp The character set used in files and log messages managed in Subversion. It's useful to set this option if you store files in Subversion using one character set but want to send notification messages in a different character set. Therefore C<encoding> would be used for the notification message, and C<svn_encoding> would be used to read in data from Subversion. See L</"Character Encoding Support"> for more information. Defaults to the value stored in C<encoding>. =item diff_encoding svnnotify --diff-encoding iso-2022-jp The character set used by files in Subversion, and thus present in the the diff. It's useful to set this option if you store files in Subversion using one character write log messages in a different character set. Therefore C<svn_encoding> would be used to read the log message and C<diff_encoding> would be used to read the diff from Subversion. See L</"Character Encoding Support"> for more information. Defaults to the value stored in C<svn_encoding>. =item language svnnotify --language fr svnnotify -g i-klingon The language typically used on the repository for log messages, file names, and file contents. Used to specify the email Content-Language header and to set the C<$LANG> environment variable to C<< $notify->language . '.' . $notify->encoding >> before executing C<svnlook> and C<sendmail> (but not for sending data to Net::SMTP). Undefined by default, meaning that no Content-Language header is output and the C<$LANG> environment variable will not be set. See L</"Character Encoding Support"> for more information. =item with_diff svnnotify --with-diff svnnotify -d A boolean value specifying whether or not to include the output of C<svnlook diff> in the notification email. The diff will be inline at the end of the email unless the C<attach_diff> parameter specifies a true value. =item attach_diff svnnotify --attach-diff svnnotify -a A boolean value specifying whether or not to attach the output of C<svnlook diff> to the notification email. Rather than being inline in the body of the email, this parameter causes SVN::Notify to attach the diff as a separate file, named for the user who triggered the commit and the date and time UTC at which the commit took place. Specifying this parameter to a true value implicitly sets the C<with_diff> parameter to a true value. =item diff_switches svnnotify --diff-switches '--no-diff-added' svnnotify -w '--no-diff-deleted' Switches to pass to C<svnlook diff>, such as C<--no-diff-deleted> and C<--no-diff-added>. And who knows, maybe someday it will support the same options as C<svn diff>, such as C<--diff-cmd> and C<--extensions>. Only relevant when used with C<with_diff> or C<attach_diff>. =item diff_content_type svnnotify --diff-content-type 'text/x-diff' Sets the Content-Type header for attached diffs. The default, if this parameter is not passed, is 'text/plain'. This parameter has no effect if '--attach-diff' is not specified. =item reply_to svnnotify --reply-to devlist@example.com svnnotify -R developers@example.net The email address to use in the "Reply-To" header of the notification email. No "Reply-To" header will be added to the email if no value is specified for the C<reply_to> parameter. =item add_headers svnnotify --add-header X-Approve=letMeIn Add a header to the notification email message. The header name and its value must be separated by an equals sign. Specify the option multiple times in order to add multiple headers. Headers with the same names are allowed. Not to be confused with the C<--header> option, which adds introductory text to the beginning of the email body. =item subject_prefix svnnotify --subject-prefix [Devlist] svnnotify -P [%d (Our-Developers)] An optional string to prepend to the beginning of the subject line of the notification email. If it contains '%d', it will be used to place the revision number; otherwise it will simply be prepended to the subject, which will contain the revision number in brackets. =item subject_cx svnnotify --subject-cx svnnotify -C A boolean value indicating whether or not to include a the context of the commit in the subject line of the email. In a commit that affects multiple files, the context will be the name of the shortest directory affected by the commit. This should indicate up to how high up the Subversion repository tree the commit had an effect. If the commit affects a single file, then the context will simply be the name of that file. =item strip_cx_regex svnnotify --strip-cx-regex '^trunk/' svnnotify --strip-cx-regex '^trunk/' --strip-cx-regex '^branches/' svnnotify -X '^trunk' svnnotify -X '^trunk' -X '^branches' One or more regular expressions to be used to strip out parts of the subject context. This can be useful for very deep Subversion trees, where the commits you're sending will always be sent from a particular subtree, so you'd like to remove part of the tree. Used only if C<subject_cx> is set to a true value. Pass an array reference if calling C<new()> directly. =item no_first_line svnnotify --no-first-line svnnotify -O Omits the first line of the log message from the subject. This is most useful when used in combination with the C<subject_cx> parameter, so that just the commit context is displayed in the subject and no part of the log message. =item header svnnotify --header 'SVN::Notify is brought to you by Kineticode. Adds a specified text to each message as a header at the beginning of the body of the message. Not to be confused with the C<--add-header> option, which adds a header to the headers section of the email. =item footer svnnotify --footer 'Copyright (R) by Kineticode, Inc.' Adds a specified text to each message as a footer at the end of the body of the message. =item max_sub_length svnnotify --max-sub-length 72 svnnotify -i 76 The maximum length of the notification email subject line. SVN::Notify includes the first line of the commit log message, or the first sentence of the message (defined as any text up to the string ". "), whichever is shorter. This could potentially be quite long. To prevent the subject from being over a certain number of characters, specify a maximum length here, and SVN::Notify will truncate the subject to the last word under that length. =item max_diff_length svnnotify --max-diff-length 1024 The maximum length of the diff (attached or in the body). The diff output is truncated at the last line under the maximum character count specified and then outputs an additional line indicating that the maximum diff size was reached and output truncated. This is helpful when a large diff output could cause a message to bounce due to message size. =item handler svnnotify --handler HTML svnnotify -H HTML Specify the subclass of SVN::Notify to be constructed and returned, and therefore to handle the notification. Of course you can just use a subclass directly, but this parameter is designed to make it easy to just use C<< SVN::Notify->new >> without worrying about loading subclasses, such as in F<svnnotify>. Be sure to read the documentation for your subclass of choice, as there may be additional parameters and existing parameters may behave differently. =item filters svnnotify --filter Trac -F My::Filter SVN::Notify->new( %params, filters => ['Markdown', 'My::Filter'] ); Specify a more module to be loaded in the expectation that it defines output filters. For example, L<SVN::Notify::Filter::Trac|SVN::Notify::Filter::Trac> loads a filter that converts log messages from Trac's markup format to HTML. L<SVN::Notify::Filter::Markdown|SVN::Notify::Filter::Markdown>, available on CPAN, does the same for Markdown format. Check CPAN for other SVN::Notify filter modules. This command-line option can be specified more than once to load multiple filters. The C<filters> parameter to C<new()> should be an array reference of modules names. If a value contains "::", it is assumed to be a complete module name. Otherwise, it is assumed to be in the SVN::Notify::Filter name space. See L<SVN::Notify::Filter|SVN::Notify::Filter> for details on writing your own output filters (it's really easy, I promise!). =item author_url svnnotify --author-url 'http://svn.example.com/changelog/~author=%s/repos' svnnotify --A 'mailto:%s@example.com' If a URL is specified for this parameter, then it will be used to create a link for the current author. The URL can have the "%s" format where the author's username should be put into the URL. =item revision_url svnnotify --revision-url 'http://svn.example.com/changelog/?cs=%s' svnnotify -U 'http://svn.example.com/changelog/?cs=%s' If a URL is specified for this parameter, then it will be used to create a link to the Subversion browser URL corresponding to the current revision number. It will also be used to create links to any other revision numbers mentioned in the commit message. The URL must have the "%s" format where the Subversion revision number should be put into the URL. =item svnweb_url svnnotify --svnweb-url 'http://svn.example.com/index.cgi/revision/?rev=%s' svnnotify -S 'http://svn.example.net/index.cgi/revision/?rev=%s' Deprecated. Use C<revision_url> instead. =item viewcvs_url svnnotify --viewcvs-url 'http://svn.example.com/viewcvs/?rev=%s&view=rev' Deprecated. Use C<revision_url> instead. =item ticket_map svnnotify --ticket-map '\[?#\s*(\d+)\s*\]?=http://example.com/ticket?id=%s' \ --ticket-map 'rt=http://rt.cpan.org/NoAuth/Bugs.html?id=%s' \ --ticket-map '\b([A-Z0-9]+-\d+)\b=http://jira/browse/%s' Specifies a mapping between a regular expression and a URL. The regular expression should return a single match to be interpolated into the URL, which should be a C<sprintf> format using "%s" to place the match (usually the ticket identifier) from the regex. The command-line option may be specified any number of times for different ticketing systems. To the API, it must be passed as a hash reference. The first example matches "[#1234]" or "#1234" or "[# 1234]". This regex should be as specific as possible, preferably wrapped in "\b" to match word boundaries. If you're using L<SVN::Notify::HTML|SVN::Notify::HTML>, be sure to read its documentation for a different regular expression requirement! Optionally, the key value can be a placeholder for a regular expression used internally by SVN::Notify to match strings typically used for well-known ticketing systems. Those keys are: =over =item rt Matches Request Tracker (RT) ticket references of the form "Ticket # 12", "ticket 6", "RT # 52", "rt 52", "RT-Ticket # 213" or even "Ticket#1066". =item bugzilla Matches Bugzilla bug references of the form "Bug # 12" or "bug 6" or even "Bug#1066". =item jira Matches JIRA references of the form "JRA-1234". =item gnats Matches GnatsWeb references of the form "PR 1234". =back =item rt_url svnnotify --rt-url 'http://rt.cpan.org/NoAuth/Bugs.html?id=%s' svnnotify -T 'http://rt.perl.org/NoAuth/Bugs.html?id=%s' A shortcut for C<--ticket-map 'rt=$url'> provided for backwards compatibility. =item bugzilla_url svnnotify --bugzilla-url 'http://bugzilla.mozilla.org/show_bug.cgi?id=%s' svnnotify -B 'http://bugs.bricolage.cc/show_bug.cgi?id=%s' A shortcut for C<--ticket-map 'bugzilla=$url'> provided for backwards compatibility. =item jira_url svnnotify --jira-url 'http://jira.atlassian.com/secure/ViewIssue.jspa?key=%s' svnnotify -J 'http://nagoya.apache.org/jira/secure/ViewIssue.jspa?key=%s' A shortcut for C<--ticket-map 'jira=$url'> provided for backwards compatibility. =item gnats_url svnnotify --gnats-url 'http://gnatsweb.example.com/cgi-bin/gnatsweb.pl?cmd=view&pr=%s' svnnotify -G 'http://gnatsweb.example.com/cgi-bin/gnatsweb.pl?cmd=view&pr=%s' A shortcut for C<--ticket-map 'gnats=$url'> provided for backwards compatibility. =item ticket_url svnnotify --ticket-url 'http://ticket.example.com/showticket.html?id=%s' Deprecated. Use C<ticket_map>, instead. =item ticket_regex svnnotify --ticket-regex '\[?#\s*(\d+)\s*\]?' Deprecated. Use C<ticket_map>, instead. =item verbose svnnotify --verbose -V A value between 0 and 3 specifying how verbose SVN::Notify should be. The default is 0, meaning that SVN::Notify will be silent. A value of 1 causes SVN::Notify to output some information about what it's doing, while 2 and 3 each cause greater verbosity. To set the verbosity on the command line, simply pass the C<--verbose> or C<-V> option once for each level of verbosity, up to three times. Output from SVN::Notify is sent to C<STDOUT>. =item boundary The boundary to use between email body text and attachments. This is normally generated by SVN::Notify. =item subject The subject of the email to be sent. This attribute is normally generated by C<prepare_subject()>. =back =cut # XXX Sneakily used by SVN::Notify::HTML.

Pass in a list of key/value pairs, where the keys are the attribute names and the values are option specifications in the format required by Getopt::Long. SVN::Notify will create accessors for each attribute, and if the corresponding value is defined, it will be used by the C<get_options()> class method to get a command-line option value. See <LSVN::Notify::HTML|SVN::Notify::HTML> for an example usage of C<register_attributes()>. =cut my %OPTS; sub register_attributes { my $class = shift; my @attrs; while (@_) { push @attrs, shift; if (my $opt = shift) { $OPTS{$attrs[-1]} = $opt; } } $class->_accessors(@attrs); } ############################################################################## =head3 get_options my $options = SVN::Notify->get_options; Parses the command-line options in C<@ARGV> to a hash reference suitable for passing as the parameters to C<new()>. See L<"new"> for a complete list of the supported parameters and their corresponding command-line options. This method use Getopt::Long to parse C<@ARGV>. It then looks for any C<handler> and C<filter> options and, if it finds any, loads the appropriate classes and parses any options they requires from C<@ARGV>. Subclasses and filter classes should use C<register_attributes()> to register any attributes and options they require. After that, on Perl 5.8 and later, it decodes all of the string option from the encoding specified by the C<encoding> option or UTF-8.

In plain English, here's what you need to know to make non-ASCII characters look right in SVN::Notify's messages: =over =item * The encoding for messages To tell SVN::Notify what character encoding to use when it sends messages, use the C<--encoding> option. It defaults to "UTF-8", which should cover the vast majority of needs. You're using it in your code already, right? =item * The character set you use in your log messages To tell SVN::Notify the character encoding that you use in Subversion commit log messages, as well as the names of the files in Subversion, use the C<--svn-encoding> option, which defaults to the same value as C<--encoding>. If, for example, you write log messages in Big5, pass C<--svn-encoding Big5>. =item * The character set you use in your code To tell SVN::Notify the character encoding that you use in the files stored in Subversion, and therefore that will be output in diffs, use the C<--diff-encoding> option, which defaults to the same value as C<--svn-encoding>. If, for example, you write code in euc-jp but write your commit log messages in some other encoding, pass C<--diff-encoding euc-jp>. =item * The locales supported by your OS SVN::Notify uses the values passed to C<--encoding>, C<--svn-encoding>, and C<--diff-encoding> to read in data from F<svnlook>, convert it to Perl's internal encoding, and to output messages in the proper encoding. Most of the time, if you write code in UTF-8 and want messages delivered in UTF-8, you can ignore these options. Sometimes, however, F<svnlook> converts its output to some other encoding. That encoding is controlled by the C<$LANG> environment variable, which corresponds to a locale supported by your OS. (See L<perllocale|perllocale/"Finding locales"> for instructions for finding the locales supported by your system.) If your system supports UTF-8 locales but defaults to using some other locale (causing F<svnlook> to output log messages in the wrong encoding), then all you have to do is pass the C<--language> option to get SVN::Notify to tell F<svnlook> to use it. For example, if all of your data is in UTF-8, pass C<--language en_US> to get SVN::Notify to use the F<en_US.UTF-8> locale. Likewise, pass C<--language sv_SE> to force the use of the F<sv_SE.UTF-8> locale. Sometimes, however, the system does not support UTF-8 locales. Or perhaps you use something other than UTF-8 in your log messages or source code. This should be no problem, as SVN::Notify uses the encoding options to determine the locales to use. For example, if your OS offers the F<en_US.ISO88591> locale, pass both C<--svn-encoding> and C<--language>, like so: --svn-encoding ISO-8859-1 --language en_US SVN::Notify will set the C<$LANG> environment variable to "en_US.ISO88591", which F<svnlook> will use to convert log messages from its internal form to ISO-8859-1. SVN::Notify will convert the output from F<svnlook> to UTF-8 (or whatever C<--encoding> you've specified) before sending the message. Of course, if you have characters that don't correspond to ISO-8859-1, you'll still get some garbage characters. It is ideal when the OS locale supports the same encodings as you use in your source code and log messages, though that's not always the case. And finally, because the names and spellings that OS vendors use for locales can vary widely, SVN::Notify will occasionally get the name of the encoding wrong, in which case you'll see warnings such as this: svnlook: warning: cannot set LC_CTYPE locale svnlook: warning: environment variable LANG is en_US.ISO88591 svnlook: warning: please check that your locale name is correct In such a case, if all of your data and your log messages are stored in the same encoding, you can set the C<$LANG> environment variable directly in your F<post-commit> script before running F<svnnotify>: LANG=en_US.ISO-88591 svnnotify -p "$1" -r "$2" If the C<$LANG> environment variable is already set in this way, SVN::Notify will not set it before shelling out to F<svnlook>. =back This looks like a lot of information, and it is. But in most cases, if you exclusively use UTF-8 (or ASCII!) in your source code and log messages, and your OS defaults to a UTF-8 locale, things should just work. =head1 See Also =over =item L<SVN::Notify::HTML|SVN::Notify::HTML> HTML notification. =item L<SVN::Notify::HTML::ColorDiff|SVN::Notify::HTML::ColorDiff> HTML notification with colorized diff. =item L<SVN::Notify::Filter|SVN::Notify::Filter> How to write output filters for SVN::Notify. =item L<SourceForge Hook Scripts|http://sourceforge.net/apps/trac/sourceforge/wiki/Subversion%20hook%20scripts> SourceForge.net support for SVN::Notify. =item L<Windows Subversion + Apache + TortoiseSVN + SVN::Notify HOWTO|http://svn.haxx.se/users/archive-2006-05/0593.shtml> Essential for Windows Subversion users. =back =head1 Support This module is stored in an open L<GitHub repository|http://github.com/theory/svn-notify/>.
