TracLegos is software designed to template trac projects and assist with trac project creation. Its goal is to make project creation easy and flexible, allowing flexibility with regards to creation methodology as well as extensibility as a project factory for environments with advanced needs. TracLegos is not meant for project upgrading or maintainence, but only to setup a project with sensible defaults.
You should be able to setup your own templates to suit your trac needs. You should be able to share these templates with others.
TracLegos can be invoked in a number of ways:
- through a command-line interface (source:traclegosscript/anyrelease/traclegos/legos.py)
- through a web-based front-end to trac (source:traclegosscript/anyrelease/traclegos/web.py)
- via paster create
- programmatically using the API
TracLegos also makes it easy to turn an existing project into a PasteScript template.
This is somewhat experimental software so feedback and feature requests are greatly appreciated
Installation and Setup
Installation is done in the typical python manner. Once you have downloaded the source, run python setup.py install for installation into python's site packages or python setup.py develop to install with edittable source.
Installation of Example Template
TracLegosScript also comes with an existing template: source:traclegosscript/anyrelease/example/oss, which is an example of the kind of template used at The Open Planning Project for open source software projects. To install this template, run python setup.py install or python setup.py develop from this directory. This PasteScript template can be seen in the output of paster create --list-templates:
(TracLegos)> paster create --list-templates Available templates: basic_package: A basic setuptools-enabled package paste_deploy: A web application deployed through paste.deploy oss_project: Open Source Software project trac template trac_project: templatize configuration for a trac project
Turning an Existing trac.ini File into a Template
The last project shown in the templates listed by paster create --list-templates, trac_project, is a template designed to turn an existing trac.ini configuration file into a TracProject template that can be used by TracLegosScript for project creation. To turn an existing configuration trac.ini into a TracProject template, run:
paster create -t trac_project yourproject
This will output a directory structure
yourproject/ |-- setup.py |-- yourproject | |-- __init__.py | |-- project.py | `-- template | `-- conf | `-- trac.ini `-- yourproject.egg-info
To customize the template, edit yourproject/yourproject/template/conf/trac.ini. PasteScript template variables can be denoted and pre and post template writing setup can be done by customizing yourproject/yourproject/project.py.
Setup of WebOb View for Project Creation
TracLegos includes a paste webapp that serves existing projects (delegating to trac) and also allows creating new projects. In order to use this view, you must have at least one template installed, so first install the example template as described above. Once the topp_trac_template (or any other template) is installed, you should be all set to run the webapp by running paster serve development.ini from the top-level directory of your copy of the TracLegos source (source:traclegosscript/anyrelease/development.ini).
Point your browser at http://127.0.0.1:8080 and you should be all set with a bare-bones web-based trac project creator.
TracLegos is designed so that site-specific configuration does not need to (and really shouldn't) live in the templates but can live in its own .ini file. The advantages of this is that templates from XYZcorp can be shared with ABCcorp without modification but that a policy for trac project creation can be effectively enforced as well as having the convenience of domain-specific variables by using a site configuration .ini file (or files). See TracLegosTemplates for a fuller explanation of how multiple templates can be used to factor out site-specific configuration.
Variables are currently supported in a site configuration file. See source:traclegosscript/anyrelease/example/site_example.ini for the format of this file. Using the command line, site configuration .ini files are specified with the -c option:
create-trac-project -c example/site_example.ini ...
Configuration files may also be specified for the web front-end. To use this, add the following option to the .ini file specified for paster serve:
traclegos.conf = /path/to/site_example.ini, /path/to/myorganization.ini
TracLegos is designed to be maleably configurable and extensible. Here are the components that make that possible:
- TracLegosTemplates : the process by which TracLegos transforms templates into trac projects
- TracLegosConfiguration : how to control what TracLegos does
Example of through the web project creation
The index of the project additionally has a Create Project link:
Following this link will bring you to the initial screen of project creation where you select the project name and type of project (if more than one template is available):
Next, the project details screen will allow selection of the type of repository (and in the future, database type -- see #3745):
Finally, you must fill in any additional variables needed for the project:
After completion, the project is created and you are redirected to it.
Example of command line usage
> create-trac-project Usage: create-trac-project [options] project <project2> <...> var1=1 var2=2 ... assemble a trac project from components Options: -h, --help show this help message and exit -c CONF, --conf=CONF site configuration files -d DIRECTORY, --directory=DIRECTORY trac projects directory -i INHERIT, --inherit=INHERIT .ini file to inherit from -s REPOSITORY, --repository=REPOSITORY repository type to use -t TEMPLATES trac.ini templates to be applied in order --list-templates list available TracProject PasteScript templates --list-repositories list repositories available for setup by TracLegos > create-trac-project --list-templates Available projects: topp_trac_project: The Open Planning Project Trac Template > create-trac-project --list-repositories Available repositories: ExistingSVN: Use an existing repository NewSVN: Create a new SVN repository > create-trac-project -t topp-trac-project mynewproject # create a new project
Example of turning an existing project into a pastescript template
> paster create -t trac_project foo Selected and implied templates: TracLegos#trac_project templatize configuration for a trac project Variables: egg: foo package: foo project: foo Enter file (file or project to templatize) ['']: /home/jhammel/20080519133401/projects/trachours/conf/trac.ini Enter description (One-line description of the package) ['']: a new trac template based on the trachours .ini file Creating template trac_project Creating directory ./foo Recursing into +package+ Creating ./foo/foo/ Copying __init__.py to ./foo/foo/__init__.py Copying project.py_tmpl to ./foo/foo/project.py Recursing into template Creating ./foo/foo/template/ Recursing into conf Creating ./foo/foo/template/conf/ Copying setup.py_tmpl to ./foo/setup.py Running /home/jhammel/TracLegos/bin/python setup.py egg_info > cd foo; python setup.py develop &> /dev/null > create-trac-project --list-templates Available projects: topp_trac_project: The Open Planning Project Trac Template foo: a new trac template based on the trachours .ini file
I haven't investigated these, but they are noted for similarity to some aspects of TracLegos
