.. contents:: Introduction ============ This package provides the core functionality of the templer code generation system. Included are a base template class, utility scripts, the templer command-line wrapper and basic templates for basic python namespace packages and nested namespace packages. All functionality of the templer system is inherited from and extends PasteScript_ templates. Templates can be generated using the syntax of that package, but the templer system provides a wrapper script to make it easier for developers to generate packages. .. _PasteScript: http://pythonpaste.org/script/ templer script -------------- This package provides a script, ``templer``. The script acts as a wrapper for PasteScript's ``paster create``, hiding the newbie-error-prone syntax of that command. The ``templer`` script also provides some inline error-checking for project names and other variables as well as additional help. It is recommended to use this script--especially for new users--rather than using ``paster create`` directly. (The resulting packages produced, however, will be the same). For example, to create a new basic namespace package invoke the script like so:: templer basic_namespace This will prompt you to provide a name for your package. The name you provide will be validated to ensure that it fits with the number of namespaces expected by the template you have chosen. Once you have set the name for your new package, You will be asked to choose a set of questions to answer. By default, only the 'easy' questions are selected, allowing you to create a new package with a minimum of interaction. However, you may choose the ``expert`` set, or even choose to answer ``all`` questions if you need more control over the final output of your package. At any time in the question-and-answer process, you may type a ``?`` at the prompt to recieve in-line assistance with the current question. If you wish to quit the process at any time during the questions, simply enter ``q`` at the prompt. Additional Script Functions --------------------------- In addition to interactively generating code, the templer script provides a number of other useful functions: ``templer --help`` provides full listings of the help text for the templer script. ``templer --list`` provides a detailed list of the available templates ``templer --version`` provides the version number of the currently installed templer package Testing ======= This package provides both unit tests for code functions and doctests for each of the provided templates. If you make changes to the package, you must ensure that these tests run successfully before checking them in. Please also contribute tests for any code you create. To run the tests, execute the following:: $ python setup.py test Debugging template issues =========================== If you have problems to execute templates like:: Error in file /Users/mikko/code/mobilize/src/templer.plone/src/templer/plone/templates/nested_plone/setup.py_tmpl: ERROR: 'str' object has no attribute 'VFFSL' Run the templates against pure Paster to get a meaningful traceback:: [~/code/mobilize/src]% ../bin/paster create -t plone_nested plone.app.mobile Selected and implied templates: templer.core#nested_namespace A basic Python project with a nested namespace (2 dots in name) templer.plone#plone_nested A package for Plone add-ons with a nested namespace ...
