PublishPlugin

Generates a static view of a web, as HTML files on disc, or as a PDF, or as a zip or tgz archive file, or by uploading directly to an FTP server.

Originally written for TWiki, previously known as GenHTMLAddOn, PublishAddOn, and PublishContrib, this is the most complete publishing solution for Foswiki.

PublishPlugin provides support for the generation of stand-alone HTML from a web. It will generate fully rendered versions of a set of Foswiki pages together with any attached files.

When you want to read a document stored in Foswiki, you have to have access to the web server that hosts that document. There are times when this may not be desirable, or even possible. For example:
  1. Foswiki is used to create documentation which has to be readable off-line
  2. Published versions of Foswiki pages must be read-only
  3. The Foswiki server is inaccessible to the audience (e.g. on the other side of a corporate firewall)
  4. You want to put product documentation on a CD
The PublishPlugin supports the generation of several different read-only document formats from Foswiki pages, including HTML and PDF.

Features

  • All standard Foswiki macros are interpreted
  • Plugins are called
  • Unresolved links to non-existent topics are silently ignored
  • Topic links internal to the wiki are translated to relative links
  • Powerful support for choosing what content gets published
  • Any links to the 'pub' areas of topics in the web are automatically resolved and the referenced files copied
  • Any links to images outside the wiki are resolved, and the image is stored in the output (requires LWP)
  • Output in HTML or PDF. HTML can be compressed in different archive formats.
  • Full support for hierarchical webs
  • Multiple instances (e.g. dev, test, prod) can be specified
  • Special output format specific templates (such as viewpdf) can be used
  • Able to publish HTML and referenced files directly to a remote server via ftp * Complete history of what was published, and when!

Usage

Publish Form

The easiest way to publish a web is from this topic, by filling in the following form.

The output is generated in a directory designated during installation. The progress messages printed during documentation generation tell you exactly where the output is. Admins can use the PublishPluginControlCentre to manage the published output.

Publishing is an access-controlled process; before you can publish, you have to have VIEW access to the topics you want to publish, and CHANGE access to the publishing history topic.

You can also create a permanent topic in a web to help with a repeated publishing process.

Choose what to publish
Web The Web to publish. web
Include (wildcard) Comma-separated list of wildcard patterns that match the names of topics to include. Use * for all topics. inclusions
Exclude (pattern) Comma-separated list of wildcard patterns that match the names of topics to exclude. Leave blank to include all topics. exclusions
Versions (topic) Name of a topic that contains a table, each row of which maps a topic names to the version of that topic to publish.
Leave blank to publish the most recent version of each topic.
The table can be generated by a %SEARCH{}% or other macro. For example: |Web.TopicName|1.33|.
If a topic does not appear in the table, the most recent version will be published.
versions
Filter topic contents (regex) A regular expression that will cause a topic to be excluded if the RE matches the topic content.
Leave blank to include all topics.
filter
Enable plugins (plugin names)
Comma-separated list of Plugins to enable during publish. Leave blank to enable all plugins.
You are recommended to disable any plugins that generate buttons in the output.
enableplugins
Output options
The output will be generated on the server, in the directory pointed to by the {PublishPlugin}{Dir} configuration setting. Administrators can manage the contents of this directory from the browser using the %PUBLISHERS_CONTROL_CENTRE% macro (See PublishPluginControlCentre).
ALERT! The rendered data can get pretty big, and the process itself puts a heavy load on the server, especially when using compression on large webs.
Publish skin The skin provides the template for how topics are published. See Skins for more informations on skins.
You are recommended to pick basic_publish, or plain, or a print skin. Your installation may also offer a special export or publish skin.
IDEA! The view template is used to generate published pages, so view.basic_publish.tmpl is the template that will be used to generate the output. You can preview any topic in this skin simply by appending ?skin=basic_publish to the end of the view URL. Note that the standard VIEW_TEMPLATE template override still works when publishing.
skin
Output format Generates HTML output (file), HTML output compressed as zip or tgz, HTML uploaded to a ftp server, or pdf. format
Publishing history topic This is where the history of your publishing is stored. Each time you publish, this topic is re-written with the log of the publishing process. You have to have "change" access to this topic. You can specify a topic in another web using the standard Web.Topic syntax. history
Web options
Web options are only relevant for web output formats (file and ftp) The web formats generate a sitemap.xml, and can also generate default.htm, index.html and google site verification files.
Google file Generates the "HTML verification file" needed to verify your site claim. See Google webmaster tools. googlefile
Default page (topic) Name of topic to used to generate default.htm, index.html defaultpage
Relative directory Path of a directory relative to {PublishPlugin}{Dir} where you want the output generated. '/' means generate the output directly in {PublishPlugin}{Dir}. relativedir
Relative URL The base URL that your published Foswiki topics will reside at, for instance to create different publishing instances like dev, test and public. Use / if you will publish to the root of your site. See also Google webmaster tools. relativeurl
FTP options
FTP options are only relevant if the output format is ftp.
The FTP output generator was written by Foswiki:Main.SvenDowideit.
Server address Set to blank to proof the output prior to uploading to your site. destinationftpserver
Server path Path to upload to on the FTP server. destinationftppath
Username FTP server user name. destinationftpusername
Password FTP server password. destinationftppassword
Fast publish Speed up the ftp publishing by only uploading modified files. This will store a (tiny) checksum (.md5) file on the server alongside each uploaded file which will be used to optimise future uploads. Recommended. fastupload
Other output generator options
Extras Some output generators support extra options (e.g. for pdf, you can add htmldoc command-line parameters here, such as --linkstyle underline). extras

Wildcard Patterns

A wildcard is a special string that you can put into a filename so that it matches a whole range of files:
String What it does Example What the example matches
* Matches any string, including an empty string. *Cheese* Every topic with "Cheese" somewhere in the name (but not "cheese")
? Matches any single character. Example1? Example10 and Example 1X but not example1
[...] Matches any one of the enclosed characters. A pair of characters separated by a hyphen denotes a range expression; any character that sorts between those two characters, inclusive, using the current locale's collating sequence and character set, is matched. If the first character following the [ is a ^ then any character not enclosed is matched. A - may be matched by including it as the first or last character in the set. A ] may be matched by including it as the first character in the set.
Within [ and ], character classes can be specified using the syntax [:class:], where class is one of the following classes defined in the POSIX.2 standard: alnum, alpha, ascii, blank, cntrl, digit, graph, lower, print, punct, space, upper, word, xdigit. A character class matches any character belonging to that class. The word character class matches letters, digits, and the character _.
B[aeiou]g Bag, Bog, Big, Beg, Bug

Regular Expressions

A perl regular expression. You can use a simple string here, which will be matched exactly, or you can read up on perl regular expressions on the web.

How-tos

Publishing a single topic

Create a link that invokes the rest script and pass the current topic in param inclusions:
<a class='foswikiPopUp'
href='%SCRIPTURLPATH{"rest"}%/PublishPlugin/publish?%REVARG%;
web=%BASEWEB%;
inclusions=%BASETOPIC%;
format=file;
skin=myskin;
defaultpage=WebHome'
rel='nofollow'>
Publish this page
</a>
(added newlines for readability).

Now you can use this link in a skin adaption to put the link (or button) on all pages. Example of a template:

%TMPL:INCLUDE{view}%

%TMPL:DEF{"printable"}%<span><a class='foswikiPopUp'
href='%SCRIPTURLPATH{"rest"}%/PublishPlugin/publish?%REVARG%;
web=%BASEWEB%;
inclusions=%BASETOPIC%;
format=file;
skin=myskin;
defaultpage=WebHome'
rel='nofollow'>Publish this page</a></span>%TMPL:END%

Using a Publish Topic (configtopic)

You can create a publish topic in a web that contains all the details needed to publish that web. This is just a topic with a series of standard preference settings (which correspond to the form parameters) in it. You can use the PublishWeb topic in this web as a template for your own topics.

Alternatively you can just take a copy of the form in this topic, paste it into your own topic, and change the defaults.

To use a publish topic, you must pass the configtopic parameter to the publish script set to the name of the topic to use to control publishing. You can specify a topic in another web using the standard Web.Topic syntax.

Publishing from the command line

Just cd to the bin directory, and perl -T rest /PublishPlugin/publish. Parameters are passed as name=value pairs, for example:
perl -T rest /PublishPlugin/publish web=Book exclusions='Web*' format=file
perl -T rest /PublishPlugin/publish web=Book inclusions=WebBook format=pdf extras='--book --duplex --toclevels=5'
The available parameter names are shown in the publish form above, in the last column.

Controlling which parts of a topic get published

You can control what gets published from a topic using %STARTPUBLISH% and %STOPPUBLISH% control tags:
  • If %STARTPUBLISH% is the first control tag seen in the file, everything before it will be ignored.
  • Everything between %STOPPUBLISH% and the next %STARTPUBLISH% (or the end of the topic) will be ignored.
  • %STARTPUBLISH% and %STOPPUBLISH% will be visible in the viewed topic, so you can easily see what will be published from the topic.
Note: the old <nopublish> tag is deprecated and should be replaced in topics

Another good trick is to set up a special "publishing" web. Create topics in the web that %INCLUDE the topics from other webs that you want to publish. You can use STARTSECTION and ENDSECTION to highlight what you want published. This way the "publishing" web gives you a view of exactly what will be in the published output, without the need for special publishing tags.

Publishing History

Every time a web is published, then the results of that publishing step are stored in a topic in the web. By default this topic is called PublishPluginHistory, but you can choose another name (see the form, above). In order to publish a web, you have to be able to write to this topic. If you need to add access controls to the topic, then make sure you do that right at the beginning of the topic, or in the hidden preferences.

The history topics contains a list of all the parameters used, and the versions of the topics that were published, so it is very useful for tracking exactly what you publish. it is written every time you run publish.

Installation Instructions

Dependencies

Note: If you want to generate PDF files, you will need an installation of htmldoc. This program is available from http://www.easysw.com/htmldoc/ for free, but you are strongly recommended to buy the commercial version. Your support for open-source projects helps make open-source software possible.

You do not need to install anything in the browser to use this extension. The following instructions are for the administrator who installs the extension on the server.

Open configure, and open the "Extensions" section. Use "Find More Extensions" to get a list of available extensions. Select "Install".

If you have any problems, or if the extension isn't available in configure, then you can still install manually from the command-line. See http://foswiki.org/Support/ManuallyInstallingExtensions for more help.

Run configure and complete the installation in the PublishPlugin section.

PDF output

Install htmldoc from http://www.easysw.com/htmldoc/

Note that htmldoc can also be used to generate PostScript by using the -t option in the Other output generator options above. See the htmldoc man pages for details.

.tgz (tar) output

Install Archive::Tar and everything it depends on

.zip output

Install Archive::Zip and everything it depends on

WARNING! Anything published is no longer under the control of Foswiki access controls, and if you make the publish output directory visible on the web then you may need to take precautions to prevent accidental leakage of confidential information by restricting web access to this directory, for example in the Apache configuration.

Info

This add-on started life as the GenHTMLAddon, written by Foswiki:Main/CrawfordCurrie at Motorola.
