Name
SVN::Notify::HTML - Subversion activity HTML notification
Synopsis
Use svnnotify in post-commit:
svnnotify --repos-path "$1" --revision "$2" \
--to developers@example.com --handler HTML [options]
Use the class in a custom script:
use SVN::Notify::HTML;
my $notifier = SVN::Notify::HTML->new(%params);
$notifier->prepare;
$notifier->execute;
Description
This subclass of SVN::Notify sends HTML formatted email messages for Subversion activity,
rather than the default plain text.
Prerequisites
In addition to the modules required by SVN::Notify, this class requires:
HTML::Entities
Usage
To use SVN::Notify::HTML, simply follow the instructions in SVN::Notify, but when using
svnnotify, specify "--handler HTML".
Class Interface
Constructor
new
my $notifier = SVN::Notify::HTML->new(%params);
Constructs and returns a new SVN::Notify object. All parameters supported by SVN::Notity
are supported here, but SVN::Notify::HTML supports a few additional parameters:
linkize
svnnotify --linkize
A boolean attribute to specify whether or not to "linkize" the SVN log message--that
is, to turn any URLs or email addresses in the log message into links.
css_url
svnnotify --css-url http://example.com/svnnotify.css
URL for a CSS file that will can style the HTML output by SVN::Notify::HTML or its
subclasses. Note that the URL will be added to the output via a "<link
rel="stylesheet">" tag after the CSS generated by SVN::Notify::HTML or its subclasses.
What that means is that the CSS file specified by "css_url" need not completely style
the HTML, but simply override the default settings. This approach nicely takes
advantage of the "cascading" abilities of CSS.
ticket_map
svnnotify --ticket-map '(BUG-(\d+))=http://bugs.example.com/?show=%s'
This attribute is inherited from SVN::Notify, but its semantics are slightly
different: the regular expression passed as the regular expression used for the key
should return two matches instead of one: the text to link and the ticket ID itself.
For example, '(BUG-(\d+))' will match "BUG-1234567", and "BUG-1234567" will be used
for the link text, while "1234567" will be used to fill in the "ticket_url" format
string. The first set of parentheses capture the whole string, while the parentheses
around "\d+" match the number only. Also note that it is wise to use "\b" on either
side of the regular expression to insure that you don't get spurious matches. So a
better version would be '\b(BUG-(\d+))\b'.
As a fallback, if your regular expression returns only a single match string, it will
be used both for the link text and for the the ticket URL generated from "ticket_url".
For example, '\bBUG-(\d+)\b' would make a link only of the number in 'BUG-1234567', as
only the number has been captured by the regular expression. But two matches are of
course recommended (and likely to work better, as well).
You can use more complicated regular expressions if commit messages are likely to
format ticket numbers in various ways. For example, this regular expression:
\b\[?\s*(Ticket\s*#\s*(\d+))\s*\]?\b'
Will match:
String Matched Link Text Ticket Number
--------------------|--------------------|---------------
[Ticket#1234] [Ticket#1234] 1234
[ Ticket # 1234 ] [ Ticket # 1234 ] 1234
Ticket #1234 Ticket #1234 1234
Ticket # 1234 Ticket #1234 1234
In any of these cases, you can see that the match is successful, properly creates the
link text (simply using the text as typed in by the committer, and correctly extracts
the ticket number for use in the URL.
To learn more about the power of Regular expressions, I highly recommend _Mastering
Regular Expressions, Second Edition_, by Jeffrey Friedl.
wrap_log
svnnotify --wrap-log
A boolean attribute to specify whether or not to wrap the log message in the output
HTML. By default, log messages are not wrapped, on the assumption that they should
appear exactly as typed. But if that's not the case, specify this option to wrap the
log message.
Class Methods
content_type
Returns the content type of the notification message, "text/html". Used to set the
Content-Type header for the message.
Instance Interface
Instance Methods
start_html
$notifier->start_html($file_handle);
This method starts the HTML of the notification message. It outputs the opening "<html>",
"<head>", and "<body>" tags. Note that if the "language" attribute is set to a value, it
will be specified in the
"<html>" tag.
All of the HTML will be passed to any "start_html" output filters. See Writing Output
Filters for details on filters.
start_body
This method starts the body of the HTML notification message. It first calls
"start_html()", and then outputs the "<style>" tag, calling "output_css()" between them.
It then outputs an opening "<div>" tag.
If the "header" attribute is set, "start_body()" outputs it between "<div>" tags with the
ID "header". Furthermore, if the header happens to start with the character "<",
"start_body()" assumes that it contains valid HTML and therefore will not escape it.
If a "start_body" output filter has been specified, it will be passed the lines with the
"<div>" tag and the header. To filter the CSS, use a "css" filter, and to filter the
declaration of the HTML document and its "<head>" section, use a "start_html" filter. See
Writing Output Filters for details on filters.
output_css
$notifier->output_css($file_handle);
This method starts outputs the CSS for the HTML message. It is called by "start_body()",
and which wraps the output of "output_css()" in the appropriate "<style>" tags.
An output filter named "css" may be added to modify the output of CSS. The filter
subroutine name should be "css" and expect an array reference of lines of CSS. See Writing
Output Filters for details on filters.
output_metadata
$notifier->output_metadata($file_handle);
This method outputs a definition list containing the meta data of the commit, including
the revision number, author (user), and date of the revision. If the "revision_url"
attribute has been set, then the appropriate URL for the revision will be used to turn the
revision number into a link.
If there are any "log_message" filters, this method will do no HTML formatting, but
redispatch to SVN::Notify::output_metadata. See Writing Output Filters for details on
filters.
output_log_message
$notifier->output_log_message($file_handle);
Outputs the commit log message in "<pre>" tags, and the label "Log Message" in "<h3>"
tags. If the "bugzilla_url" attribute is set, then any strings like "Bug 2" or "bug # 567"
will be turned into links.
If there are any "log_message" filters, the filters will be assumed to escape the HTML,
create inline links, and link ticket URLs. Otherwise, this method will do those things.
See Writing Output Filters for details on filters.
output_file_lists
$notifier->output_log_message($file_handle);
Outputs the lists of modified, added, deleted, files, as well as the list of files for
which properties were changed as unordered lists. The labels used for each group are
pulled in from the "file_label_map()" class method and output in "<h3>" tags.
If there are any "file_lists" filters, this method will do no HTML formatting, but
redispatch to SVN::Notify::output_file_lists. See Writing Output Filters for details on
filters.
end_body
$notifier->end_body($file_handle);
Closes out the body of the email by outputting the closing "</body>" and "</html>" tags.
Designed to be called when the body of the message is complete, and before any call to
"output_attached_diff()".
If the "footer" attribute is set, "end_body()" outputs it between "<div>" tags with the ID
"footer". Furthermore, if the footer happens to end with the character "<", "end_body()"
assumes that it contains valid HTML and therefore will not escape it.
All of the HTML will be passed to any "end_body" output filters. See Writing Output
Filters for details on filters.
output_diff
$notifier->output_diff($out_file_handle, $diff_file_handle);
Sends the output of "svnlook diff" to the specified file handle for inclusion in the
notification message. The diff is output between "<pre>" tags, and Each line of the diff
file is escaped by "HTML::Entities::encode_entities()". The diff data will be read from
$diff_file_handle and printed to $out_file_handle.
If there are any "diff" filters, this method will do no HTML formatting, but redispatch to
SVN::Notify::output_diff. See Writing Output Filters for details on filters.
Accessors
