Name ^

SVN::Notify - Subversion activity notification

Synopsis ^

Use svnnotify in post-commit:

  svnnotify --repos-path "$1" --revision "$2" \
    --to developers@example.com [options]

  svnnotify --repos-path "$1" --revision "$2" \
    --to-cx-regex i10n@example.com=I10N [options]

Use the class in a custom script:

  use SVN::Notify;

  my $notifier = SVN::Notify->new(%params);
  $notifier->prepare;
  $notifier->execute;

Description ^

This class may be used for sending email messages for Subversion repository activity. There are a number of different modes supported, and SVN::Notify is fully subclassable, to add new functionality, and offers comprehensive content filtering 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 with_diff and attach_diff options below.

Usage ^

To use SVN::Notify, simply add a call to svnnotify to your Subversion repository's post-commit script. This script lives in the hooks directory at the root of the repository directory; consult the documentation in post-commit.tmpl for details. Make sure that you specify the complete path to svnnotify, as well as to svnlook and sendmail in the options passed to svnnotify so that everything executes properly. And if you specify any string options, be sure that they are in the encoding specified by the --encoding option, or UTF-8 if you have not specified --encoding.

Windows Usage

To get SVN::Notify to work properly in a post-commit script, you must set the following environment variables, as they will likely not be present inside Apache:

PATH=C:\perl\bin
OS=Windows_NT
SystemRoot=C:\WINDOWS

See Windows Subversion + Apache + TortoiseSVN + SVN::Notify HOWTO for more detailed information on getting SVN::Notify running on Windows. If you have issues with asynchronous execution, try using HookStart.exe to run svnnotify.

Class Interface ^

Constructor

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 svnnotify. The options have the same names as these parameters, but any underscores you see here should be replaced with dashes when passed to svnnotify. Most also have a corresponding single-character option. On Perl 5.8 and higher, If you pass parameters to new(), they must be decoded into Perl's internal form if they have any non-ASCII characters.

Supported parameters:

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 post-commit. So you can simply pass $1 to this parameter if you like. See the documentation in post-commit for details. Required.

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 post-commit. So you can simply pass $2 to this parameter if you like. See the documentation in post-commit for details. Required.

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 to_regex_map or to_email_map is specified.

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 to or to_email_map is specified.

The command-line options, --to-regex_map and -x, can be specified any number of times, once for each entry in the hash to be passed to 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 Getopt::Long documentation for more information.

Here's an example complements of Matt Doar of how to use 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
to_email_map
  svnnotify --to-email-map L18N=translate@example.com \
            --to-email-map License=legal@example.com

The inverse of to_regex_map: The regular expression is the hash key and the email address or addresses are the value.

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 svnlook info.

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 svnlook info is usually something like a Unix login name. SVN::Notify will use this username in the email "From" header unless the 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 \@$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 user_domain parameter.

svnlook
  svnnotify --svnlook /path/to/svnlook
  svnnotify -l /path/to/svnlook

The location of the svnlook executable. If not specified, SVN::Notify will search through the directories in the $PATH environment variable, plus in /usr/local/bin and /usr/sbin, for an svnlook executable. Specify a full path to svnlook via this option or by setting the $SVNLOOK environment variable if svnlook isn't in your path or to avoid loading File::Spec.

It's important to provide a complete path to svnlook because the environment during the execution of post-commit is anemic, with nary a $PATH environment variable to be found. So if 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 svnlook executable.

sendmail
  svnnotify --sendmail /path/to/sendmail
  svnnotify -s /path/to/sendmail

The location of the sendmail executable. If neither the sendmail nor the smtp parameter is specified, SVN::Notify will search through the directories in the $PATH environment variable, plus in /usr/local/bin and /usr/sbin, for an sendmail executable. Specify a full path to sendmail via this option or by setting the $SENDMAIL environment variable if sendmail isn't in your path or to avoid loading File::Spec. The same caveats as applied to the location of the svnlook executable apply here.

set_sender
  svnnotify --set-sender
  svnnotify -E

Uses the -f option to 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 from option, be sure to make it only an email address. Don't include any other junk in it, like a sender's name. Ignored when using smtp.

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 sendmail to send the message. If sendmail is not installed locally (such as on Windows boxes!), you must specify an SMTP server.

smtp_tls
  svnnotify --smtp-tls

Use TLS authentication and encrypted channels for connecting with the server. Usually, TLS servers will require user/password authentication.

smtp_user
  svnnotify --smtp-user myuser

The user name for SMTP authentication. If this option is specified, SVN::Notify will use Net::SMTP_auth to send the notification message, and will of course authenticate to the SMTP server.

smtp_pass
  svnnotify --smtp-pass mypassword

The password for SMTP authentication. Use in parallel with smtp_user.

smtp_port
  svnnotify --smtp-port 465

The port for an SMTP server through which to send the notification email. The default port is 25.

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 EHLO command. See "TLS and AUTHentication" in Net::SMTP::TLS for details.

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 language parameter is specified, the $LANG environment variable when launching sendmail. See "Character Encoding Support" for more information. Defaults to "UTF-8".

charset
  svnnotify --charset UTF-8

Deprecated. Use encoding instead.

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 encoding would be used for the notification message, and svn_encoding would be used to read in data from Subversion. See "Character Encoding Support" for more information. Defaults to the value stored in encoding.

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 svn_encoding would be used to read the log message and diff_encoding would be used to read the diff from Subversion. See "Character Encoding Support" for more information. Defaults to the value stored in svn_encoding.

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 $LANG environment variable to $notify->language . '.' . $notify->encoding before executing svnlook and sendmail (but not for sending data to Net::SMTP). Undefined by default, meaning that no Content-Language header is output and the $LANG environment variable will not be set. See "Character Encoding Support" for more information.

with_diff
  svnnotify --with-diff
  svnnotify -d

A boolean value specifying whether or not to include the output of svnlook diff in the notification email. The diff will be inline at the end of the email unless the attach_diff parameter specifies a true value.

attach_diff
  svnnotify --attach-diff
  svnnotify -a

A boolean value specifying whether or not to attach the output of 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 with_diff parameter to a true value.

diff_switches
  svnnotify --diff-switches '--no-diff-added'
  svnnotify -w '--no-diff-deleted'

Switches to pass to svnlook diff, such as --no-diff-deleted and --no-diff-added. And who knows, maybe someday it will support the same options as svn diff, such as --diff-cmd and --extensions. Only relevant when used with with_diff or attach_diff.

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.

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 reply_to parameter.

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 --header option, which adds introductory text to the beginning of the email body.

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.

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.

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 subject_cx is set to a true value. Pass an array reference if calling new() directly.

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 subject_cx parameter, so that just the commit context is displayed in the subject and no part of the log message.

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 --add-header option, which adds a header to the headers section of the email.

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.

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.

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.

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 SVN::Notify->new without worrying about loading subclasses, such as in svnnotify. Be sure to read the documentation for your subclass of choice, as there may be additional parameters and existing parameters may behave differently.

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, SVN::Notify::Filter::Trac loads a filter that converts log messages from Trac's markup format to HTML. 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 filters parameter to 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 SVN::Notify::Filter for details on writing your own output filters (it's really easy, I promise!).

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.

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.

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 revision_url instead.

viewcvs_url
  svnnotify --viewcvs-url 'http://svn.example.com/viewcvs/?rev=%s&view=rev'

Deprecated. Use revision_url instead.

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 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 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:

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".

bugzilla

Matches Bugzilla bug references of the form "Bug # 12" or "bug 6" or even "Bug#1066".

jira

Matches JIRA references of the form "JRA-1234".

gnats

Matches GnatsWeb references of the form "PR 1234".

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 --ticket-map 'rt=$url' provided for backwards compatibility.

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 --ticket-map 'bugzilla=$url' provided for backwards compatibility.

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 --ticket-map 'jira=$url' provided for backwards compatibility.

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 --ticket-map 'gnats=$url' provided for backwards compatibility.

ticket_url
  svnnotify --ticket-url 'http://ticket.example.com/showticket.html?id=%s'

Deprecated. Use ticket_map, instead.

ticket_regex
  svnnotify --ticket-regex '\[?#\s*(\d+)\s*\]?'

Deprecated. Use ticket_map, instead.

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 --verbose or -V option once for each level of verbosity, up to three times. Output from SVN::Notify is sent to STDOUT.

boundary

The boundary to use between email body text and attachments. This is normally generated by SVN::Notify.

subject

The subject of the email to be sent. This attribute is normally generated by prepare_subject().

Class Methods

content_type

  my $content_type = SVN::Notify->content_type;

Returns the content type of the notification message, "text/plain". Used to set the Content-Type header for the message.

register_attributes

  SVN::Notify::Subclass->register_attributes(
      foo_attr => 'foo-attr=s',
      bar      => 'bar',
      bat      => undef,
  );

This class method is used by subclasses to register new attributes. 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 get_options() class method to get a command-line option value.

See <LSVN::Notify::HTML|SVN::Notify::HTML> for an example usage of register_attributes().

get_options

  my $options = SVN::Notify->get_options;

Parses the command-line options in @ARGV to a hash reference suitable for passing as the parameters to new(). See "new" for a complete list of the supported parameters and their corresponding command-line options.

This method use Getopt::Long to parse @ARGV. It then looks for any handler and filter options and, if it finds any, loads the appropriate classes and parses any options they requires from @ARGV. Subclasses and filter classes should use 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 encoding option or UTF-8. This allows options to be passed to SVN::Notify in that encoding and end up being displayed properly in the resulting notification message.

file_label_map

  my $map = SVN::Notify->file_label_map;

Returns a hash reference of the labels to be used for the lists of files. A hash reference of file lists is stored in the files attribute after prepare_files() has been called. The hash keys in that list correspond to Subversion status codes, and these are mapped to their appropriate labels by the hash reference returned by this method:

  { U => 'Modified Paths',
    A => 'Added Paths',
    D => 'Removed Paths',
    _ => 'Property Changed'
  }

find_exe

  my $exe = SVN::Notify->find_exe($exe_name);

This method searches through the system path, as well as the extra directories /usr/local/bin and /usr/sbin (because they're common paths for svnlook and sendmail for an executable file with the name $exe_name. The first one it finds is returned with its full path. If none is found, find_exe() returns undef.

Instance Interface ^

Instance Methods

prepare

  $notifier->prepare;

Prepares the SVN::Notify object, collecting all the data it needs in preparation for sending the notification email. Really it's just a shortcut for:

  $notifier->prepare_recipients;
  $notifier->prepare_contents;
  $notifier->prepare_files;
  $notifier->prepare_subject;

Only it returns after the call to prepare_recipients() if there are no recipients (that is, as when recipients are specified solely by the to_regex_map or to_email_map parameter and none of the regular expressions match any of the affected directories).

prepare_recipients

  $notifier->prepare_recipients;

Collects and prepares a list of the notification recipients. The recipients are a combination of the value passed to the to parameter as well as any email addresses specified as keys in the hash reference passed to_regex_map parameter or values passed to the to_email_map parameter, where the corresponding regular expressions stored in the hash matches one or more of the names of the directories affected by the commit.

If the subject_cx parameter to new() has a true value, prepare_recipients() also determines the directory name to use for the context.

prepare_contents

  $notifier->prepare_contents;

Prepares the contents of the commit message, including the name of the user who triggered the commit (and therefore the contents of the "From" header to be used in the email) and the log message.

prepare_files

  $notifier->prepare_files;

Prepares the lists of files affected by the commit, sorting them into their categories: modified files, added files, and deleted files. It also compiles a list of files wherein a property was set, which might have some overlap with the list of modified files (if a single commit both modified a file and set a property on it).

If the subject_cx parameter was specified and a single file was affected by the commit, then prepare_files() will also specify that file name as the context to be used in the subject line of the commit email.

prepare_subject

  $notifier->prepare_subject;

Prepares the subject line for the notification email. This method must be called after prepare_recipients() and prepare_files(), since each of those methods potentially sets up the context for use in the the subject line. The subject may have a prefix defined by the subject_prefix parameter to new(), it has the revision number, it might have the context if the subject_cx specified a true value, and it will have the first sentence or line of the commit, whichever is shorter. The subject may then be truncated to the maximum length specified by the max_sub_length parameter.

execute

  $notifier->execute;

Sends the notification message. This involves opening a file handle to sendmail or a tied file handle connected to an SMTP server and passing it to output(). This is the main method used to send notifications or execute any other actions in response to Subversion activity.

output

  $notifier->output($file_handle);
  $notifier->output($file_handle, $no_headers);

Called internally by execute() to output a complete email message. The file a file handle, so that output() and its related methods can print directly to the email message. The optional second argument, if true, will suppress the output of the email headers.

Really output() is a simple wrapper around a number of other method calls. It is thus essentially a shortcut for:

    $notifier->output_headers($out) unless $no_headers;
    $notifier->output_content_type($out);
    $notifier->start_body($out);
    $notifier->output_metadata($out);
    $notifier->output_log_message($out);
    $notifier->output_file_lists($out);
    if ($notifier->with_diff) {
        my $diff_handle = $self->diff_handle;
        if ($notifier->attach_diff) {
            $notifier->end_body($out);
            $notifier->output_attached_diff($out, $diff_handle);
        } else {
            $notifier->output_diff($out, $diff_handle);
            $notifier->end_body($out);
        }
    } else {
        $notifier->end_body($out);
    }
    $notifier->end_message($out);

output_headers

  $notifier->output_headers($file_handle);

Outputs the headers for the notification message headers. Should be called only once for a single email message.

output_content_type

  $notifier->output_content_type($file_handle);

Outputs the content type and transfer encoding headers. These demarcate the body of the message. If the attach_diff parameter was set to true, then a boundary string will be generated and the Content-Type set to "multipart/mixed" and stored as the boundary attribute.

After that, this method outputs the content type returned by content_type(), the character set specified by the encoding attribute, and a Content-Transfer-Encoding of "8bit". Subclasses can either rely on this functionality or override this method to provide their own content type headers.

start_body

  $notifier->start_body($file_handle);

This method starts the body of the notification message, which means that it outputs the contents of the header attribute, if there are any. Otherwise it outputs nothing, but see subclasses for other behaviors.

output_metadata

  $notifier->output_metadata($file_handle);

This method outputs the metadata of the commit, including the revision number, author (user), and date of the revision. If the author_url or revision_url attributes have been set, then the appropriate URL(s) for the revision will also be output.

output_log_message

  $notifier->output_log_message($file_handle);

Outputs the commit log message, as well as the label "Log Message".

output_file_lists

  $notifier->output_file_lists($file_handle);

Outputs the lists of modified, added, and deleted files, as well as the list of files for which properties were changed. The labels used for each group are pulled in from the file_label_map() class method.

end_body

  $notifier->end_body($file_handle);

Closes out the body of the email by outputting the contents of the footer attribute, if any, and then a couple of newlines. Designed to be called when the body of the message is complete, and before any call to output_attached_diff().

output_diff

  $notifier->output_diff($out_file_handle, $diff_file_handle);

Reads diff data from $diff_file_handle and outputs it to to $out_file_handle.

output_attached_diff

  $notifier->output_attached_diff($out_file_handle, $diff_file_handle);

Reads diff data from $diff_file_handle and outputs it to to $out_file_handle as an attachment.

end_message

  $notifier->end_message($file_handle);

Outputs the final part of the message,. In this case, that means only a boundary if the attach_diff parameter is true. Designed to be called after any call to output_attached_diff().

run_ticket_map

  $notifier->run_ticket_map( \&callback, @params );

Loops over the ticket systems you have defined, calling the $callback function for each one, passing to it the regex, url and @params specified as its parameters.

run_filters

  $data = $notifier->run_filters( $output_type => $data );

Runs the filters for $output_type on $data. Used internally by SVN::Notify and by subclasses.

filters_for

  my $filters = $notifier->filters_for( $output_type );

Returns an array reference of of the filters loaded for $output_type. Returns undef if there are no filters have been loaded for $output_type.

diff_handle

  my $diff = $notifier->diff_handle;
  while (<$diff>) { print }

Returns a file handle reference providing access to the the commit diff. It will usually be passed as the second argument to output_diff() or output_attached_diff().

  $notifier = $notifier->to($to);
  my @tos = $notifier->to;
  $notifier = $notifier->to(@tos);

This attribute is used to set the $LANG environment variable, if it is not already set by the environment, before executing svnlook. It is not used for svnlook diff, however, as the diff itself will be emitted in raw octets except for headers such as "Modified", which need to be in English so that subclasses can parse them. Thus, $LANG is always set to "C" for the execution of svnlook diff.

Character Encoding Support

SVN::Notify has comprehensive support for character encodings, but since it cannot always know what encodings your system supports or in which your data is stored in Subversion, it needs your help. In plain English, here's what you need to know to make non-ASCII characters look right in SVN::Notify's messages:

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.
