ZopeSkel 2.19

Buildout installation

Add to your buildout.cfg:

parts =
    ...
    zopeskel


[zopeskel]
recipe = zc.recipe.egg
eggs =
        ZopeSkel
        ${instance:eggs}

After building your buildout, this will leave zopeskel and paster commands in the bin directory of your buildout.

Virtualenv installation

First, install virtualenv into your system:

easy_install virtualenv

Next, create a virtual environment with the new virtualenv command:

virtualenv --no-site-packages --distribute zopeskelenv

Once virtualenv is finished, you can install zopeskel to your new virtual environment:

zopeskelenv/bin/easy_install zopeskel

Once this is complete, you will be left with zopeskel and paster commands in the bin directory inside your virtualenv.

Using local commands to create a content type package

Starting inside your Plone buildout, first create an archetypes package:

cd src
../bin/zopeskel archetype mycompanyid.mycustomcontenttypes

Next, change directories into your new package and invoke paster to add a content type:

cd mycompanyid.mycustomcontenttypes
../../bin/paster

Usage: ../../bin/paster COMMAND
usage: paster [paster_options] COMMAND [command_options]

...

Commands:
...

ZopeSkel local commands:
        addcontent   Adds plone content types to your project

As you can see from the paster command output, your new package supports a local command called addcontent. Tou can use addcontent command to add new code to your package. As with both zopskel and paster, you can use the --list option to see what local commands are available in the context of the package you’ve created.

../../bin/paster addcontent –list

Available templates:

atschema: A handy AT schema builder browserlayer: A Plone browserlayer contenttype: A content type skeleton form: A form skeleton formfield: Schema field for a form i18nlocale: An i18n locale directory structure portlet: A Plone 3 portlet view: A browser view skeleton zcmlmeta: A ZCML meta directive skeleton

You can add an archetypes content type for managing lectures:

../../bin/paster addcontent -t contenttype LectureInfo

Then you can add schema fields to that content type:

../../bin/paster addcontent -t atschema

local commands can be run as many times as needed to create your package. You can iteratively develop your content type, other content types, and more.

2.19 - January 21, 2011

• In every setup.py, replace ‘%3A’ with ‘:’, making list_classifier url an url which can actually be used. [thet]

• Added plone4_buildout [miohtama]

• Improvements to README [miohtama]

2.18 - September 30, 2010

• Add bin/zopeskel –version flag. Reports current version of zopeskel (http://plone.org/products/zopeskel/issues/48) [cewing]

• plone3_buildout: use Plone 3.3.5 by default. [maurits]

• Fixed a problem with the generic setup profile in plone templates in which a profile was registered in zcml, but no profiles directory was created. (http://plone.org/products/zopeskel/issues/46) [cewing]

• use i18n:domain plone for portlet title so it need not be translated twice (http://plone.org/products/zopeskel/issues/44) [fRiSi]

• use the correct name of package, so it can be used in package with 2 dots or 1 dots in package name [lucmult]

2.17 - June 14, 2010

• Added a pin for PasteScript>=1.7.2. This solves an issue where using zopeskel with an early version of PasteScript resulted in a method signature mismatch on the paster command ‘challenge’ method. Fixes issue #42 (http://plone.org/products/zopeskel/issues/42) [cewing]

• Fixed lingering problem in Archetypes template with registering a ‘locales’ directory before one is created. Users now need to add an i18nlocale via addcontent in order to get this directory and have it registered via zcml. [cewing]

• Fixed dependency in Archetypes template doctests on the presence of the log-in portlet. Tests now open the ‘login_form’ instead. Resolves issue #40 (http://plone.org/products/zopeskel/issues/40) [cewing]

• Added new browserlayer localcommand for plone and archetype templates. [marcosfromero]

• Added stub locales directory for plone3_theme template, resolving issue #33 (http://plone.org/products/zopeskel/issues/33) [cewing]

• Set the GenericSetup profile version number in the generated metadata.xml to 1000, which is better for the alphabetical ordering that GS does. [maurits]

• Added “environment-vars = zope_i18n_compile_mo_files true” to plone3_buildout template. This is enabled only for Plone 4 (eggifiedzope is true). [vincentfretin]

2.16 - March 22, 2010

• Fixed syntax error in generated portlet constructor code [ajung]

• Added a new ‘BoundedIntVar’ variable type. It validates that the provided argument is both an integer and between provided min and max values (inclusive on both ends). [cewing]

• Updated archetype and plone3_portlet templates to comply with pep8 and pyflakes validation at all stages of a skeleton build process. Resolves the issue here: (http://plone.org/products/zopeskel/issues/24) [cewing]

• Added explanatory text to the plone_hosting template regarding the fact that it is unsuitable for use with plone versions later than 3.1.7, fixed http://plone.org/products/zopeskel/issues/25 [cewing]

• Fixed the problem with generated archetypes content type meta_type names documented here: (http://plone.org/products/zopeskel/issues/22) [cewing]

• Updated tests for the plone template to include tests for the fixes to message factory, zcml sub-package include and i18n translation registration problems below [cewing]

• Cleaned up a number of issues with defining and importing a package-wide MessageFactory in plone template local commands: (http://plone.org/products/zopeskel/issues/29) [cewing]

• Cleaned up a number of issues with importing sub-package zcml files after using local commands in the plone template: (http://plone.org/products/zopeskel/issues/28) [cewing]

• Fixed an issue with the plone template zcmlmeta local command to ensure that the proper directive was inserted into the top-level configure.zcml [cewing]

• Fixed the bug in the plone template that caused zcml errors when the i18nlocale local command had not been run: (http://plone.org/products/zopeskel/issues/26) [cewing]

• Improved i18n for portlets (http://plone.org/products/zopeskel/issues/31) [fRiSi]

• Improved test coverage of the zopeskel script [cewing]

• Disallowed use of the paster –svn-repository command due to some basic incompatibilities with the way zopeskel is used. The argument is still allowed for users via ‘paster create’. (http://plone.org/products/zopeskel/issues/34 http://plone.org/products/zopeskel/issues/35) [cewing]

• Added a ‘Register Profile’ question to the plone template so that users can have a Generic Setup profile registered in the case that they plan on adding things (like portlets) that require a GS Profile to install. Adapted downstream templates archetype, plone25_theme and plone3_theme to use the new question [cewing]

2.15 - January 22, 2010

• Backed out a few changes from jaroel in favor of retaining working templates OOTB [cewing]

• Made archetype, plone3_theme and plone3_portlet pass the PEP8 validator and pyflakes. [jaroel]

• Template summaries (one-line descriptions) were improved. [pupq]

• Templates now have an optional help attribute, which is a rich description of the template and its purpose. Help has been provided for all the ZopeSkel templates. [pupq/cewing]

• Variables (questions in templates) now have a human-facing “title” attribute which can be shown instead of the (uglier + more opaque) actual variable name. Titles have been written for questions. [pupq]

• Variables now have optional help attribute, which is a rich description of the variable. This can be shown in pastescript UIs. [pupq]

• Interactive help has been added, so that you can enter “?” at any question to receive the rich help for that question. [cewing]

• “Modes” have been implemented–easy, expert, and all–to reduce the number of questions posed to beginning users. For example, technical questions (like “namespace package 2”) are now shown only in expert mode. [cewing/pupq]

• The project name (eg, “plone.app.example”) is now split into pieces to become the default values for namespace packages names (“plone”, “app”, “example”). [pupq]

• Templates can provide an ndot attribute that signals how many namespaces (“dots”) are expected in the project name. When invoked through new zopeskel front-end script, names that don’t support that pattern are rejected with help (eg, creating a plone_app with “plone.example” would be rejected, as a 2-namespaced-name, “plone.foo.example”, is expected) [pupq]

• Rather than having to use the checkvar() and post() methods, templates can now support messages that appear pre-questions and post-generation. Appropriate warnings and where-to-go help has been added. [cewing]

• Abstract classes for zope2 products and buildouts have been added; this simplifies inheritance of common attrs, and provides appropriate places for future common logic. [pupq]

• A front-end script, ‘zopeskel’, has been added. This has high-level, friendly help, and an improved command line interface for the task of template usage. It can provide a friendly list of templates and a verbosely-detailed list of templates. [pupq/cewing/chrisrossi]

• Users can have a “$HOME/.zopeskel” script with default values for questions, either on a all-template or template-by-template basis. [pupq]

• The “zopeskel” script can emit a sample “.zopeskel” file, for editing. [pupq/cbc]

• A simple HTML help generator can produce a listing of templates, fields, and subtemplates. This will be useful for maintaining an HTML “reference guide” to the ZopeSkel templates. Find this in the zopeskel.doctools package. [pupq/cbc]

• Currently-failing unit tests were fixed. [pupq/cewing]

• New unit tests were written for new features. [cewing]

• New and repaired unit tests were added into the default test suite [cewing]

• Rather than using a generic var() class for all variables (“questions”), subclasses for different types of variables–string, boolean, choices, etc.–were added. These normalize their own values and provide validation. Therefore, users will get earlier/better feedback on inappropriate values. [pupq/cewing]

• A proposal for splitting the project into zopeskel.* packages was added. [pupq/cbc]

• Where questions were duplicated across different templates, they were consolidated for consistency into one place, and referred to from other places. [pupq]

• A real-time tool for generating graphs of dependencies and template inheritance was written, suitable for including in high-level documentation. Find this in the zopeskel.doctools package. [cbc]

• Use the eggified Zope 2.12.3 for buildouts targeting Plone 4.x. Use 2.9.12 for buildouts targeting Plone 2.x. [maurits]

• Remove unnecessary ‘title’ argument from jsregistry.xml example. This fixes http://plone.org/products/zopeskel/issues/18. [dukebody]

2.14.2 - December 8th, 2009

• Back out untested, undocumented changes from paris sprint that broke some templates [MatthewWilkes]

2.14.1 - November 19th, 2009

• Fix packaging error [MatthewWilkes]

2.14 - November 19th, 2009

• Use the eggified Zope 2.12.1 for buildouts targeting Plone 4.x. Bump 3.x default version to 3.3.2. [MatthewWilkes]

• Use distribute for Plone buildouts [MatthewWilkes]

• Remove extra quotes in a plone_pas template file, which were generating a syntax error. [dukebody]

2.13 - October 3rd, 2009

• Pinned Cheetah to <= 2.2.1 and eliminated install_requires for elementtree (markdown not a requirement for Cheetah 2.2.1). Allows zopeskel to easy_install with python 2.4. Can remove pinning when markdown is fixed. [cbcunc]

• plone3_buildout: added ‘fake-zope-eggs = true’ to the zope2 part, as otherwise you get e.g. ‘ImportError: No module named ImplPython’ when using a plone.recipe.zope2install < 3.0, like pinned by Plone 3.2 versions.cfg. [maurits]

• Make the Plone 3 buildout template default to Plone 3.3.1. [dukebody]

• Modify HISTORY.txt convention in basic_namespace and nested_namespace templates. Use now “1.0dev (unreleased)” and ‘-’ for changelog items. [vincentfretin]

• Fix trove classifiers list url in all setup.py_tmpl [vincentfretin]

• Remove old import_steps.xml from profiles/default/ in plone3_theme template, the various import step in registered in profile.zcml now. [vincentfretin]

• For plone3_theme, plone3_portlet an archetype templates, start profile version at 1 to follow current convention. [vincentfretin]

• Remove http://download.zope.org/ppix/, http://download.zope.org/distribution/, and http://effbot.org/downloads from find-links in the plone3_buildout template. Only Pypi or http://dist.plone.org/release/${plone_version} is really needed. Add http://dist.plone.org/thirdparty for alternative location for elementree, PILwoTk, markdown, python-ldap. [vincentfretin]

2.12 - September 23rd, 2009

• Remove the options fake-zope-eggs=true and additional-fake-eggs=ZODB3 in the plone3_buildout template since fake-zope-eggs is enabled by default in plone.recipe.zope2install>=3.0, with ZODB3 among the default “fake zope eggs”. [dukebody]

• Declare a dependency on elementtree. It’s not a direct dependency of ZopeSkel, but ZopeSkel depends on Cheetah which depends on Markdown, which has an install-time dependency on elementtree but doesn’t declare that. [davisagli]

• remove the custom egg_info.writer and keywords for paster_plugins since this has been an entry point of PasteScript since 1.6.3, using the setup_requires as per the change log found here: http://pythonpaste.org/script/news.html#id4

  This solves an issue where the distutils would go into an infinite loop when you add a new install_requires package [claytron]

• plone3_theme: made the generated viewlet.pt not crash when the accompanying view has not been changed so has no computed_value. Added some inline documentation there and fixed example registration. [maurits]

• In the plone3_theme say that we are creating a theme for Plone 3, not specifically for 3.0. [maurits]

• In the plone template fix the generated INSTALL.txt: when telling users to add $project to the eggs, the example snippet should indeed add $project and not the $full_package_name. [maurits]

• In the plone_app and plone3_portlet templates use the full package name instead of the project name in zcml lines in the generated INSTALL.txt. The project/package/egg name may be ‘silly’ when the package structure is far/better/name, which means the zcml needs to be ‘far.better.name’. Thanks to Espen Moe-Nilssen for spotting this. [maurits]

• Make the Plone 3 buildout default to Plone 3.2.2. [maurits]

• Removed the setup.cfg from all templates. It makes the common operation of tagging and releasing packages harder with little benefit. It can be easily added by those who know about this particular feature. [hannosch]

• Removed the useless Python Modules trove classifier from all templates. [hannosch]

2.11 - February 5th, 2009

• Make the Plone 3 buildout default to Plone 3.2.1, and pick up ${versions:zope2-url} for Plone > 3.1 [MatthewWilkes]

• added a version requirement for Cheetah (>1.0) [tarek]

• fix zopeskel/docs/localcommands.txt [yboussard]

• Modify zopeskel/templates/plone/+namespace_package+/+package+/tests.py_tmpl to init egg as product if it is a Zope2 product. [yboussard]

• Modify plone3_buildout template to ask for a Plone version. If the version is 3.0 or 3.1 it uses the plone install recipe, otherwise it uses the Plone egg from the cheeseshop. [MatthewWilkes]

• Link to appropriate PyPI pages for recipes used. [MatthewWilkes]

• Add a Zope 2 without Plone buildout template. [evilbungle]

• Reconciling HISTORY.txt to mirror what can be found at the following: http://pypi.python.org/pypi/ZopeSkel/2.10. Release of 2.10 was clobbered due to what looks like a merge at r74790. [andrewb]

• Update plone2.5_template’s buildout.cfg_tmpl to use Zope 2.9.10. This release incorporates Hotfix-2008-08-12. Defaulting to a known insecure Zope seems unwise for people that may be updating legacy environments into buildout, since they’re likely to forget to include the hotfix. Url to 2.9.10 hard-coded (as opposed to the more elegantly self-aware plone.recipe.plone approach) per the practice of a plone.recipe.distros plone part. [andrewb]

• Nearly at the end of the creation of a ZopeSkel template, the local commands available for that template are displayed. [jaraco, markvl]

• The Plone template now has local commands. (Basically moved them from the archetype templates to plone templates and made them available for both. [markvl]

• Added base test setup to the archetype template. Added wiring code that runs README.txt as a doctest. [esartor]

• Added tests to the addcontent contenttype command. These ammend the README.txt file for each content type providing basic tests for creating, editing and removing instances of the added content type. [esartor]

2.10 - September 17th, 2008

• Fixed a small bug that made most templates create a package that was

• showing twice in the Plone quick installer is the top level namespace package was called ‘Products’. Bug was fixed in the ‘plone’ template (since version 1.5), now in other ones where needed too. [davconvent]

2.9 - September 1st, 2008

• Update silva buildout to reflect changes in Silva 2.1 as stable version, and 2.2 as development: SilvaLayout is not shipped anymore as an extra distribution but integrated in Silva all. Remove question, and update buildout.cfg template. [thefunny]

2.8 - July 31, 2008

• Generate logrotate configuration file using collective.recipe.template so it does not need to contain absolute paths. This makes it possible to move the generated buildout around, or install it on other machines with different filesystem layouts. [wichert]

• Also rotate instance1-Z2.log. [wichert]

• Update documentation for hosting template to note that logrotate needs to be told where to put its status file. [wichert]

2.7 - July 25, 2008

• Hosting template:

  • Switch default Plone version to 3.1.4. [wichert]

  • Corrected a typo in the logrotate template, which prevented the zeo log to be rotated. [hannosch]

2.6.2 - July 16, 2008

• Hosting template:

  • Corrected even more references of instance to instance1 in proxy support and logrotate handling. [hannosch]

2.6.1 - July 16, 2008

• Hosting template:

  • Changed the http_port to start at base_port + 10, to make room for additional services. [hannosch]

  • Corrected hide_summary option, to not show the summary twice. [hannosch]

2.6 - July 15, 2008

• Hosting template:

  • Corrected one last reference of instance to instance1 in the zopepy eggs option of the plone_hosting template. [hannosch]

2.5 - July 15, 2008

• Hosting template:

  • fix test for Varnish-support in the supervisord configuration. [wichert]

  • Rename the instance part to instance1 and add an instances group. This makes it possible to upgrade to multiple instances later on without having to break invocations. [wichert]

2.4 - July 9, 2008

• Restore the cwd after running buildout in the hosting recipe so further processing works correctly. [wichert]

• Add a hook in the hosting template to not show the summary. This can be used by derived templates that want to show their own summary or show it at a later point. [wichert]

• Set default Plone version to 3.1.3. [wichert]

• Added kss plugin template [gotcha, jfroche, adrien01]

• Silva layout have been merged with Silva all in the development buildout. [thefunny]

2.3 - June 24, 2008

• Fix problem in the hosting template: varnish was always enabled even if not desired. [wichert]

• Added ZopeSkel test layer with the apropriate testSetup and testTearDown. The steps in the top of each test file is not anymore needed: delete tempdir/plone.example and then cd to tempdir. [mustapha]

• Make the zope2product option in the archetype template default to true. [mustapha]

• Modified buildout.cf to only test zopeskel. [mustapha]

• Fixed the paster test function: overwrite option should default to True for the create command. [mustapha]

• Added use_local_commands attribute (a la use_cheetah). A zopeskel template that wants to use local commands has to set it to True . [mustapha]

• Get rid of zopeskel.txt and use setup.cfg to store the parent template name. [mustapha]

• Sub-templates may define a parent_template attribute with the list of templates that can use it. [mustapha]

• Fixed tests and updated docs. [mustapha]

Version 2.2

• Install Plone 3.1.2 by default. [wichert]

• Remove useless spans from the portlet template. [wichert]

• Add supervisorctl configuration. [wichert]

Version 2.1

• Revert BaseTemplate usage from the hosting template (changeset 57368 from Tarek). It was not used and broke the buildout. This fixes http://plone.org/products/zopeskel/issues/8 [wichert]

• Replace the generic README in the plone_hosting template with documentation that is important for deployments. [wichert]

• Add log rotation support to the hosting buildout. Merged from Jarn’s bones package. [wichert]

Version 2.0

• Switch plone_hosting template to using supervisord to manage processes. Merged from Jarn’s bones package. [wichert]

• Reduced the number of questions to generate an atschema and used the MessageFactory instead of declaring an i18n_domain attribute [mustapha]

• Fixed missing imports in plone2_theme [mustapha]

• Removed unused imports in plone_pas [mustapha]

• In plone2.5_theme: when the skinname is empty, replace it with a default text, otherwise adding a Plone Site will throw an error when displaying the extension profiles. [maurits]

• Added note to profiles.zcml of plone2.5_theme that five.registerPackage needs Five version 1.4. [maurits]

• Added a BUILDBOT.txt file. [tarek]

• plone3_portlet: added commented out alternative AddForm for when there are no configurable parameters. That was shorter than listing all the changes (where we forgot one). [maurits]

• Fixed typos in archetyps and plone3 portlets: ‘portletBotomLeft’ should have been ‘portletBottomLeft’ with two ‘t’s. [maurits]

• Made plone3_portlet respect pep8 (and pyflakes). [maurits]

• Use 1.0 as default version number for all templates. This is a more sensible default than 0.1 since we start of with dev-versions anyway. [wichert]

• sub-templates per ZopeSkel template: Only sub-templates related to the parent template is visible with the -l option [mustapha]

• added -a (–list-all) option to show all subtemplates regardless of the current project. Subtemplates that are not for the type of the current project are prefixed with N [mustapha]

• Fixed the recreation of the paster_plugins.txt metadata file for archetype. For now we have to run 2 times the egg_info command to get the paster_plugins file recreated (setuptools problem: nice task to fix) [mustapha]

• fixed the case of many inner packages: ask the user to choose a packe to inject content into if the command is run outside of an inner package [mustapha]

• make all ZopeSkel templates that inherits from BaseTemplate addcontent aware [mustapha]

• Added plone_pas template for PlonePas projects and many subtemplates [mustapha]

• regrouped archetype subtemplates in templates/archetype [mustapha]

• added and fixed tests [mustapha]

Version 1.10

• Install Plone 3.1.1 as default option. [wichert]

• Fixed a problem with ZopeSkel localcommands when we have multiple projects, it was getting the first directory always and sometimes the package dir was not the first directory, so when running the addcontent in the package it was creating the contents in the wrong dir. Thanks to wichert for pointing me this file. [dsa]

• Update the hosting template to make running of buildout optional. [wichert]

• Update the hosting template to test if a port is already in use and abort if so. [wichert]

• Update the hosting template to only ask for a single base port number. [wichert]

• Fix broken creation of Plone 3.1(.x) sites. [wichert]

Version 1.9

• Install Plone 3.1 as default option. [wichert]

• Fixed a missing ‘import os’ in the plone2_theme template. [davisagli]

• Fix an ambiguous question in the silva_buildout template, and update the generated README file. [thefunny]

Version 1.8

• fixed the recipe template buildout.cfg generation, thanks Kai ;) [tarek]

Version 1.7

• Update the templates to have README.txt and HISTORY.txt in valid restructured format and use those as the package’s long description. This automatically gives packages a more readable page on PyPI (and PSC with Tarek’s excellent changes). [wichert]

• Adjust the trove classifiers on the packages to not claim incorrect frameworks: we should only claim frameworks on which the package can run directly. So, for example, do not claim Zope2 of we also need Plone on top of Zope2. [wichert]

Version 1.6

• Add templates for a Silva buildout. [thefunny]

• Add a metadata.xml to all generated GenericSetup profiles. This is required by new versions of GenericSetup. [wichert]

• For nested namespace packages we need to declare both namespace levels as namespace packages. This is a requirement for current versions of setuptools. [wichert]

• Use Plone 3.0.6 as default version for new Plone hosting buildouts [wichert]

Version 1.5.1

• Fix #2 (missing import in ‘hosting.py’) at http://plone.org/products/zopeskel/issues/2 [nouri]

Version 1.5

• added a new local command into archetype template to inject new content types [spanky]

• added a doctest for each template, and refactored the package so we have one python module per template [tarek]

• Refactored the zc.buildout recipe to provide structured documention that will render nicely on PyPI, added comments for recipe authors to help writing documentation and tests and added a working doctest skeleton. Implemented automatic license classifiers for common licenses in the generated setup.py. The mapping is in zopeskel.base and can be used for other templates also. [dokai]

• The ‘five:registerPackage’ ZCML directive is added in a project based on the ‘plone’ template only if the top level namespace package is not called ‘Products’. This avoids having the product loaded twice in Zope. [davconvent]

• Added paragraph about old style Zope 2 Product installation in the INSTALL.txt_tmpl file of the plone template. The paragraph will be added to the installation instructions if the top level namespace package is called ‘Products’. [davconvent]

Version 1.4

• Set the version number for plone.recipe.plone in a new versions part in buildout.cfg. That works around a buildout bug: buildout breaks if you change the revision pin for a recipe. [wichert]

• Fixed bug: when running ‘paster create’ with –no-interactive option, the package variable given in the command line is ignored. [Mustapha]

Version 1.3.4

• Added MANIFEST.in to prevent bad releases from svn exports. [fschulze]

Version 1.3.3

• Move to the newly released Varnish 1.1.2. [wichert]

• Remove bad import which broke localcommand support. [deo]

• Remove unneeded imports and whitespace cleanup. [deo]

Version 1.3.2

• Small fix in plone3_theme that did not install correctly with easy_install because of some files missing the the egg informations (added MANIFEST.in). [davconvent]

Version 1.3.1

• Added ‘addcontent’ local command to make possible injecting content types in ZopeSkel projects and make the Archetype template ‘addcontent’ aware. [mustapha]

• Updated to Plone 3.0.4. [fschulze]

• Rerelease because of a bad egg. [fschulze]

Version 1.3

• added the recipe template [tarek]

• Add Plone 2.5.5. [wichert]

Version 1.2

• Merge a slightly stripped down version of the Jarn Plone hosting template. This provides a convenient way to create a buildout for all Plone 2.5 and 3.0 versions with ZEO and optional Varnish based caching. [wichert]
