Foswiki Developer Environment

Automates build and packaging process, including installer generation, for extension modules.

Summary of Contents

BuildContrib can be used to create a build script for your extension. It is inspired by the Java ANT build tool developed by the Apache project, but is targeted specifically at building Foswiki extensions. It is also used for Foswiki release builds. The advantage of using BuildContrib is that it dictates a standard structure and build procedure, which makes your extension easier for you, and others, to build and maintain.

Features:
  • not just for building code modules, can also be used to package WikiApplications, and even pure documentation packages.
  • automatically generates an installer script that can help simplify end-user installation.
  • includes a wizard script for creating a new extension.
  • supports creating collections of extensions.

Notes
  • This is a build and packaging module for use by developers, not an install module for end users (though it does build an installer script, among other things).
  • The module has only been tested on Linux, but should work with Cygwin OK.

Fast Start

If you don't like reading documentation, and just want a fast route to creating a new extension, then:
  1. Install the contrib using the instructions below
  2. cd to the root of your installation
  3. perl create_new_extension.pl extension_name
then modify the extension files as required (including MANIFEST). Then when you are ready to create archives:
  1. perl build.pl extension_name release
    • Archives (.zip, .tgz) will be created in extension_name

Development Model

The build module assumes:
  1. two kinds of extension modules; 'Plugins', and 'Contribs' (everything else e.g Skins, WikiApplications etc),
  2. you have some passing familiarity with build tools such as make,
  3. you are not developing your extension in a 'production' installation (something that is usually a really bad idea), but are instead doing the sensible thing and developing in a separate directory tree
    • usually - but not always - a subversion checkout area.

Standard directory structure

BuildContrib is used to build the Foswiki core, as well as most extensions. This document will focus on its use for building extensions. See the tools/build.pl file in a subversion checkout for information on building the core.

Extensions are developed in subdirectories of the checkout. For example, BathPlugin will be developed in BathPlugin. This directory is called the root directory for the extension.

The standard directory structure under a root directory mirrors a standard installation tree. Every plugin has some key files:
  • lib/
    • Foswiki/
      • Plugins/
        • name.pm - code file for the plugin, usually derived from EmptyPlugin
        • name/ - directory containing sub-modules used by your plugin, and for storing your build.pl script and other support files. It is referred to as the module directory
          • build.pl - build script for this extension
          • MANIFEST - list of files to be installed
          • DEPENDENCIES - list of modules this extension depends on
          • Config.spec - configure setup for this extension
  • data/
    • System/
      • name.txt - your plugin/contrib topic
  • test/
    • unit/
      • name/ - directory containing unit tests for the extension
  • pub/
    • System/
      • name/ - directory where all your images, css, and Javascript files should go
Contribs are held in the lib/Foswiki/Contrib directory instead of lib/Foswiki/Plugins but otherwise in exactly work the same way.

Other directories normally found in a Foswiki installation may also exist under a root directory e.g. bin, templates etc.

While development in a subversion checkout is strongly recommended, it is also possible to develop in a normal Foswiki install. To do this, simply install the BuildContrib.

Setting up for Development

The first thing to do is to either
  • check out a development environment from subversion, or
  • create a separate, fresh, install for development.
Configure this install so it's a running installation; we'll refer to this as your dev install.

Now install the BuildContrib. In a subversion checkout, cd to the installation root and perl pseudo-install.pl BuildContrib. In a non-subversion environment, install the BuildContrib package. Make sure that all installed files are readable by the webserver user.

Environment Variables

Your build script has to know how to find the Foswiki libraries, so it can pick up the components of the build system. Set FOSWIKI_LIBS (which is a path, same as PERL5LIB) to point to your lib directory in your development Foswiki. $FOSWIKI_LIBS is used to extend @INC _for the duration of the build only_, so it won't mask problems during testing.

The approach we recommend is to set FOSWIKI_LIBS in your login script (e.g. .login, .csh, .profile depending on what shell you prefer).

EXPERTS build.pl does not read bin/setlib.cfg. It uses $FOSWIKI_LIBS only to find the modules for the BuildContrib.

Build script

Each individual extension has its own build script, called build.pl, in its module directory. A build script is a perl script that takes a number of targets as its parameters. For example, perl build.pl test will run unit tests, and perl build.pl release will build a new release.

The build script also accepts the following options:
-n Do nothing; just print what you would have done
-v Be verbose
-topiconly with target upload, only upload the topic (not the archives)

Build targets are Perl functions, which operate on various data defined in control files to build the various targets. Perl is used rather than make for portability reasons.

The targets you will normally use are:
build perform basic build steps
compress Generate compressed versions of JavaScript and CSS files
tidy Run Perl::Tidy on all perl modules listed in the MANIFEST
test run unit tests
release build, pod and package a release zip
upload build, pod, release and upload
manifest print a guess at the MANIFEST (Caution - omits the primary System/Extension.txt topic
history Generates a list of svn checkins with comments suitable for use in the history section of the plugin/contrib topic.
dependencies Find and print a best-guess dependencies list (for DEPENDENCIES)

The default target is test. The BuildContrib is designed so that most common behaviour is catered for. It is also easy to override any of the default targets in your build.pl and add extra behaviours.

The build target

Does nothing by default. This is the first target executed, and can be overridden by your build.pl to do something unusual - for example, executing an ANT file to build some Java.

The compress target

Usually only used if your extension includes Javascript or CSS, this target minifies a file to generate another that is functionally identical, but smaller for faster download. It uses CPAN:JavaScript::Minifier and CPAN:CSS::Minifier to perform the compression.

The compression can work with a number of different naming schemes, depending on what files you refer to in your MANIFEST. For example, the name mappings for javascript are:
  1. XXX_src.js -> XXX.js
  2. XXX_src.js -> XXX.compressed.js
  3. XXX.uncompressed.js -> XXX.compressed.js
  4. XXX.uncompressed.js -> XXX.js
  5. XXX.js -> XXX.compressed.js
i.e. if you list XXX.compressed.js in MANIFEST, then the build will look for XXX.uncompressed.js or XXX.js in the source tree to generate it from. XXX.compressed.js will be regenerated even if it exists in the source tree itself. If you list XXX.js in MANIFEST, then the build will look for a XXX.uncompressed.js or XXX_src.js in the sources to generate it from. The new files are generated in the source tree, so can be used for pseudo installation and testing. However they are not checked in.

The easiest way to use compressed sources is to select the version your code is to use based on a switch when you include the headers. For example, you can use the DEBUG global from the Assert module:
use Assert; # Standard Foswiki ASSERT module
...
my $pack = DEBUG ? '.uncompressed' : '.compressed';
Foswiki::Func::addToHEAD(<<SCRIPT);
<script type="text/javascript" src="%PUBURLPATH%/%SYSTEMWEB%/MyPlugin/my$pack.js">
<link rel="stylesheet" type="text/css" href="%PUBURLPATH%/%SYSTEMWEB%/MyPlugin//my$pack.css" />
</script>
SCRIPT
When DEBUG is defined (i.e. when ASSERT is enabled), this will include my.uncompressed.js and my.uncompressed.css, which makes debugging easier. If DEBUG is not defined, it will include my.compressed.js and my.compressed.css instead for best performance.

If you have your own debugging flag in your extension, you could use that instead of DEBUG.

The tidy target

This target runs Perl::Tidy (with default formatting options) over your source code. This reformats the code consistently with the Foswiki coding standards.

The test target

The test target is designed for use with extensions that have unit tests written using the UnitTestContrib. It automatically runs the unit tests found in the test/unit/extension_name directory.

The release target

The results of the release target are:
  • a Zip format archive,
  • a gzipped tar archive,
  • a md5 checksum,
  • the extension topic,
  • an installer script

The archives will each contain the following:
  1. All the files listed in the MANIFEST
  2. Another copy of the install/uninstall scripts

The tracked target

The tracked target is a special case of the release target. Given the name of a customer, it will calculate a ciphered ID and replace %$TRACKINGCODE% in the sources and documentation with the calculated code. It will then make a release for that specific customer that includes the tracking code. This is useful where you want to be able to trace the code back to that customer without revealing any details about them.

To use this target, you must manually add %$TRACKINGCODE% into your sources and documentation.

The upload target

This target builds a release, and then tries to upload it to a target repository. The target uploads all the files in the release, and also tries to upload any attachments to the extension topic (as found by scanning the topic for META:FILEATTACHMENT).

You can control what server the upload is done to. This lets you - for example - set up your own corporate extensions server. Note that the upload operation will first attempt to download the topic to recover the PackageForm so that it can be added to the newly uploaded topic. The upload also gives you a chance to specify an alternate download location to be used for PackageForm recovery.

The manifest and dependencies targets

These are used when you are unsure of the correct contents of MANIFEST and DEPENDENCIES. They make a best-guess at the required contents for these files.

The twiki target

TWiki® is the precursor of Foswiki, and some support for building extensions for TWiki is built in to the BuildContrib.

Firstly, extensions that were developed for use with the old TWiki BuildContrib can be built using the Foswiki BuildContrib. Just modify the build.pl to load the Foswiki build system rather than the old TWiki build system.

Secondly, BuildContrib has a special target, twiki, which can be used with a Foswiki build script to generate a TWiki directory structure and build script, that can then be used to build an extension targeted at TWiki. The files in the extension are run through a number of "mapping rules" that will map much of the Foswiki namespace to TWiki. This transformation is not complete, because Foswiki has many more features than TWiki, and because CSS and Javascript cannot be reliably transformed this way. However many extensions will work in TWiki after this transformation, and for others it can be used as a launchpad for further manual mapping steps.

Example,
$ cd EditRowPlugin/lib/Foswiki/Plugins/EditRowPlugin
$ perl build.pl twiki

WARNING: no .txt was generated
WARNING: no _installer was generated
There is no TWiki-specific topic generated. The Foswiki topic should suffice. Installer generation is also disabled using !option installers none in the tranformed MANIFEST. Users must install the generated TWiki packages manually from the command-line. This is required due to bugs in TWiki.

Note the TWiki_ prefix on the archive names. This is useful to avoid naming clashes with the standard Foswiki release of the same package. It is defined using !option archive_prefix TWiki_ in the tranformed MANIFEST.

Extension authors are strongly recommended to check the functioning of the TWiki versions of their extensions very carefully.

TWiki® is a trademark of Peter Thoeny.

MANIFEST

The MANIFEST file contains a list of all the files that are wanted in the package. Each line is a file path, relative to the root of the installation. Wildcards may NOT be used. If the path contains spaces it must be enclosed in double-quotes.

Each file path has an optional octal permissions mask and a description. For example,
data/System/BathPlugin.txt 0664 Plugin description topic
lib/Foswiki/Plugins/BathPlugin.pm 0444 Plugin code module
If no permissions are given, permissions are guessed from the permissions on the file in the source tree. These permissions are used by the installer script to set file permissions in the installation.

The following permissions are recommended, and will be applied by default if you don't specify anything different:
File type Permissions Meaning
.pm file 0444 Anyone can read, but cannot write or execute
.pl file 0554 Anyone can read, user and group can also execute
data/....txt file 0664 Anyone can read, only owner can write
File in pub/ 0644 ditto
File in bin/ 0555 Anyone can read or execute, but not write
Anything other file 0444 Anyone can read, but cannot write or execute
directories 0775 default directories to traversable

Do not include:
  • ,v files. If you include a ,v file it will overwrite any existing ,v file when an extension is upgraded, potentially wiping out local changes on the end users installation.
  • build.pl, MANIFEST, or any other side file used by the build process.
  • unit tests

Directives

MANIFEST files can contain a number of directives that are used to control aspects of the build process. These directives always start with an exclamation mark (!) and must be on a line on their own.

!ci and !noci

By default, files in the data and pub directories are automatically checked in to Foswiki when the installation script is run (for example, when installing from configure). This is useful when you expect users to customise your files locally and you don't want to risk overwriting their customisations. If you want to suppress this checkin behaviour for individual files, you can add the string (noci) anywhere in the description of the file. If you want to suppress it for larger numbers of files, you can use the !noci and !ci directives in the MANIFEST. Any files listed after a !noci directive, up to the next !ci directive or the end of the file, will not be checked in when installing to Foswiki 1.0.1 or later

!include

MANIFESTs can also include other extensions that have been packaged using BuildContrib. For example,
!include WysiwygPlugin/lib/Foswiki/Plugins/WysiwygPlugin
This will include the WysiwygPlugin in the release package.

Note that there is a script in the Foswiki tools directory called check_manifest.pl that can be run at any time to check the contents of your MANIFEST against what is checked into Subversion.

!option

!option is a general directive used to define global options. Currently supported options are:
  • !option archive_prefix String_ will prefix the name of generated archive files with =String_
  • !option installer none will suppress the generation of an installer script.

DEPENDENCIES

The DEPENDENCIES file specifies dependencies on other extensions and perl modules. Each line of the file is a single dependency:
name, version, type, description
where
  • name is the name of the module,
    • For Foswiki/TWiki/and CPAN modules, write the full module path, Foswiki::Plugins::MyPlugin
    • For external modules, use a "well known" name that can be understood by other package managers. Alternative packaging like .deb packages can resolve these external dependencies.
  • version is the version constraint (e.g. ">1.5"),
    • If version is written as r1234 (r followed by 1-6 digit number), the SVN release of the module will be compared, instead of the version.
    • Legacy dependencies - if written as a simple 4-digit number, will be assumed to be a SVN release number.
  • type is its type (cpan, perl, or eternal)
    • cpan modules should be found in the CPAN repositories.
    • perl modules include Foswiki:: and TWiki:: modules.
    • external or any other value is reported but ignored.
  • description is a short description of the module and where to get it. If it begins with the word Optional then the dependency will not be automatically resolved.

ALERT! Dependencies of type cpan or perl will be executed in an eval %statement to compare the VERSION and RELEASE strings.

The installer script written by the build process uses the dependency type to decide how to install dependant modules. 'cpan' means 'get the module from CPAN' and 'perl' means 'get the module from the Plugins web on Foswiki.org' (or whatever other repositories the admin has specified using $FOSWIKI_PACKAGES or $PLUGINS_URL).

Calculating DEPENDENCIES

When your module (the depender) depends on another module (a dependee), it is important to think carefully about what version of the dependee your module requires.

When you are working with Foswiki modules (such as contribs and plugins) you should list the version number of the module that you tested with. Normally you will want to use a > condition, so that more recent versions will also work. If a dependency on a Foswiki module fails (because the module isn't installed, for example) then the installer script will pull the latest version of the module from Foswiki.org, whether that is the required version or not. This is a limitation of the way plugins are stored on Foswiki.org.

As an alternative to using the Version number, you can also compare to the SVN release number. Write the version string as >=r1234. Note that the Version number is the preferred method, and is reported to the user during the install.

When you are working with CPAN modules, you need to take account of the fact that there are two types of CPAN modules; built-ins and add-ons.

Built-ins are perl modules that are pre-installed in the perl distribution. Since these modules are usually very stable, it is generally safe to express the version dependency as ">0" (i.e. "any version of the module will do").

Note however that the list of built-in modules is constantly growing with each new release of perl. So your module may be installed with a perl version that doesn't have the required module pre-installed. In this case, CPAN will automatically try to upgrade the perl version! There is no way around this, other than for the admin on the target system to manually install the module (download frm CPAN and build locally). You can help out the admin by expressing the dependency clearly, thus:

File::Find,>0,cpan,This module is shipped as part of standard perl from perl 5.8.0 onwards. If your perl installation is older than this, you should either upgrade perl, or manually install this module. If you allow this installer to continue, it will automatically upgrade your perl installation which is probably not what you want!

ONLYIF

A dependency may optionally be preceded by a condition that limits the cases where the dependency applies. The condition is specified using a line that contains ONLYIF ( condition ), where condition is a Perl conditional. This is most useful for enabling dependencies only for certain versions of other modules. For example,
File::Munge,>0,cpan,...
ONLYIF ( $Foswiki::Plugins::VERSION < 1.025)
MyPackage::FixOldFileFind, >=1.000, perl, Optional, only required if we have an old version of Foswiki API.
The ONLYIF only applies to the next dependency in the file.

Writing a build script

The easiest way to write a new build script is to use the create_new_extension.pl script, which is part of the BuildContrib.
  1. Create your plugin source tree
    • perl create_new_extension.pl BathPlugin
    • if you are working in a Subversion checkout, move the directory just created up one level to be at the same level as core.
  2. Edit lib/Foswiki/Plugins/BathPlugin.pm as required to create your plugin functionality
  3. Edit lib/Foswiki/Plugins/BathPlugin/MANIFEST and make sure it lists all the files you want to include in the release package
During development we recommend you use the pseudo-install.pl script to soft-link your development code into your dev install. This script uses the MANIFEST you write and creates softlinks (copies, on Windows) in your dev install that allow you to run your test code without having to do a full re-install each time you make a change.

If you have a pre-existing extension, and you want to package it for use with BuildContrib, then you (may) need to create the module directory and write the build.pl, MANIFEST and DEPENDENCIES files. The easiest way to do this is to copy those files from an existing extension in subversion, and modify them for your use.

Preparing the Installer

The installer script generated by the builder when target release is used is based on a template. This template is populated with lists of files and dependencies needed to make the extension-specific installer script.

PRE and POST processing scripts

You can extend this script by providing PREINSTALL, POSTINSTALL, PREUNINSTALL, and/or POSTUNINSTALL files in the module directory. These optional files are embedded into the template install script at the appropriate stage of the installation. Read lib/Foswiki/Contrib/BuildContrib/TEMPLATE_installer.pl (in the BuildContrib) to see how they fit in.

With the Foswiki 1.1 version of the install tools, these exits run as methods of the Configure::Package object instance for the extension, and have access to the package manifest and other information. See the PerlDoc for Foswiki::Configurer::Package for details.

If the script needs to report to the installer, it should return the message as a simple string ending with a newline. It will be presented as a verbatim block to the web install, or as inline text for the shell installation.

ALERT! Caution: The pre/post scripts should not assume the standard installation directories or topics when used to remove or otherwise manipulate files in the installation. You can use the Utility function mapTarget to find the correct file location for the current install. See PerlDoc for Foswiki::Configure::Util

Also, as the file to be removed is most likely not listed in the manifest, it will not be backed up during the install. So use caution removing files that would be required if fallback to the prior version of the plugin is necessary.

For example, the POSTINSTALL script might look for an obsolete file from a previous install, map it to the correct location for this installation, and delete it if it exists.

    my $this = shift;   # Get the object instance passed to the routine
    if ($this) {        # Verify that you are running in the new environment
        # Map the standard location to the absolute location on this
        # installation of Foswiki.   mapTarget is only available in Foswiki >= 1.1
        my $mapped = Foswiki::Configure::Util::mapTarget( $this->{_rootdir}, 'tools/obsolete.pl');
        my $count = unlink $mapped if ( -e $mapped ); # If it exists, delete it. 
        return "Removed $mapped \n " if ($count);
        }

Testing

You are stongly recommended to develop a unit test suite for your extension. Unit tests are kept in the test/unit/<name> directory for each extension.

To run the unit tests you will need to set up the test environment as described in Foswiki::Development.GettingStarted

The easiest way to generate tests for your extension is to copy the approach taken in another extension. See for example ActionTrackerPlugin and CommentPlugin, which both have extensive test suites.

Tests are run using
  • perl build.pl test

Building a release

When you are almost ready to release, you should
  1. Build a release package and installer
    • cd BathPlugin/lib/Foswiki/Plugins/BathPlugin
    • perl build.pl release
  2. Remove the softlinked version from your dev install
    • cd dev install
    • perl pseudo-install.pl -uninstall BathPlugin
  3. Install the release package you just built:
    • cd dev install
    • perl BathPlugin/BathPlugin_installer
  4. Test.

Token expansion

The release target automatically expands certain tokens in .txt files and in the installer script. The following tokens are supported:
  • %$MANIFEST% - table of files in MANIFEST
  • %$FILES% - hash keyed on file name mapping to permissions i.e. 'data/System/ThsiTopic.txt' => 0664, 'lib/Foswiki/Plugins/BlahPlugin.pm' => 0775
  • %$DEPENDENCIES% - list of dependencies from DEPENDENCIES
  • %$VERSION% subversion number and the date of the most recent checkin
  • %$RELEASE% value of the $RELEASE perl global variable from your master perl module
  • %$DATE% - local date
  • %$POD% - POD documentation for the package, excluding test modules.
  • %$PREINSTALL% - contents of PREINSTALL
  • %$POSTINSTALL% - contents of POSTINSTALL
  • %$PREUNINSTALL% - contents of PREUNINSTALL
  • %$POSTUNINSTALL% - contents of POSTINSTALL
  • %$BUGSURL% - URL of bugs web
  • %$INSTALL_INSTRUCTIONS% - basic instructions for installing
Note configure uses the | Version: | row in the table in the extension topic to determine what version of the package is installed. In the sources this is normally set to | Version: | 7573 (2010-05-27) |. When you perl build.pl release, 7573 (2010-05-27) is computed by finding the most recent subversion checkin of any file listed in MANIFEST, so it's very reliable and low maintenance. You don't have to use 7573 (2010-05-27) in the | Version: | row of the extension topic - you can use your own version string if you want, or you can use 27 May 2010 which will take whatever value you have assigned to the $RELEASE variable in the extension master perl module. configure supports all of subversion revision numbers, manually generated triples (1.2.3), ISO dates, and dd Mmmm yyy format dates as valid revision identifiers.

Upload

When you are happy the release package is built correctly, you can upload it.
  • cd BathPlugin/lib/Foswiki/Plugins/BathPlugin
  • perl build.pl upload
By default the upload target will upload to Foswiki.org. You will be prompted to enter an alternate upload target, should you require it (e.g. to upload to private corporate repository). The upload updates the topic and any associated Var topics published by the extension, and uploads zip, tgz, md5 and installer files.

Install support

Installer scripts build by BuildContrib are important for the full functioning of the extensions installer in configure.

The installer script shipped with the package is very simple. By default all it does is to check the dependencies you list, and if necessary download and install any missing Foswiki and CPAN modules. Other dependencies are simply checked. Topics shipped with the module are automatically merged into any existing local copies, ensuring histories are preserved.

If you want your installer to do anything else then you will need to write a POSTINSTALL script.

Installation Instructions

You are strongly recommended to use this Contrib to help split your code development away from your live Foswiki environment, as described above.

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.
