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
<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 HookStart.exe
<http://www.koders.com/csharp/fidE2724F44EF2D47F1C0FE76C538006435FA20051D.aspx> 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()".

first value in the list, for backwards compatibility with older versions of SVN::Notify. In list context,
it of course returns the entire list. Pass in one or more values to set all of the values for the "to"
attribute.

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:
• The encoding for messages
To tell SVN::Notify what character encoding to use when it sends messages, use the "--encoding"
option. It defaults to "UTF-8", which should cover the vast majority of needs. You're using it in
your code already, right?
• 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 "--svn-encoding" option, which defaults to the same
value as "--encoding". If, for example, you write log messages in Big5, pass "--svn-encoding Big5".
• 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 "--diff-encoding" option, which defaults to the same
value as "--svn-encoding". If, for example, you write code in euc-jp but write your commit log
messages in some other encoding, pass "--diff-encoding euc-jp".
• The locales supported by your OS
SVN::Notify uses the values passed to "--encoding", "--svn-encoding", and "--diff-encoding" to read
in data from 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, svnlook converts its output to some other encoding. That encoding is controlled
by the $LANG environment variable, which corresponds to a locale supported by your OS. (See
perllocale 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 svnlook to output log
messages in the wrong encoding), then all you have to do is pass the "--language" option to get
SVN::Notify to tell svnlook to use it. For example, if all of your data is in UTF-8, pass "--language
en_US" to get SVN::Notify to use the en_US.UTF-8 locale. Likewise, pass "--language sv_SE" to force
the use of the 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 en_US.ISO88591
locale, pass both "--svn-encoding" and "--language", like so:
--svn-encoding ISO-8859-1 --language en_US
SVN::Notify will set the $LANG environment variable to "en_US.ISO88591", which svnlook will use to
convert log messages from its internal form to ISO-8859-1. SVN::Notify will convert the output from
svnlook to UTF-8 (or whatever "--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 $LANG environment variable directly in your post-commit script before running svnnotify:
LANG=en_US.ISO-88591 svnnotify -p "$1" -r "$2"
If the $LANG environment variable is already set in this way, SVN::Notify will not set it before
shelling out to svnlook.
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.
