=head1 Name
SVN::Notify - Subversion activity notification
=head1 Synopsis
Use F<svnnotify> in F<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;
=head1 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 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>.

=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 directories 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()>.

=head3 register_attributes
SVN::Notify::Subclass->register_attributes(
foo_attr => 'foo-attr=s',

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 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()>.

=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. This allows options
to be passed to SVN::Notify in that encoding and end up being displayed
properly in the resulting notification message.

$notifier = $notifier->to($to);
my @tos = $notifier->to;
$notifier = $notifier->to(@tos);
Gets or sets the list of values stored in the C<to> attribute. In a scalar
context, it returns only the 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 C<to> attribute.
=head3 to_regex_map
my $to_regex_map = $notifier->to_regex_map;
$notifier = $notifier->to_regex_map($to_regex_map);

Gets or sets the value of the C<add_headers> attribute, which is a hash
reference of the headers to be added to the email message. If one header needs
to appear multiple times, simply pass the corresponding hash value as an array
reference of each value for the header. Not to be confused with the C<header>
accessor, which gets and sets text to be included at the beginning of the body
of the email message.

=head2 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:
=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>.

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.
