If you are looking for new macros, or have written one that you would like to share, please visit that site. - -== Developing Custom Macros - -Macros, like Trac itself, are written in the [http://python.org/ Python programming language] and are developed as part of TracPlugins. - -For more information about developing macros, see the [trac:TracDev development resources] on the main project site. - -Here are 2 simple examples showing how to create a Macro. Also, have a look at [trac:source:tags/trac-1.0.2/sample-plugins/Timestamp.py Timestamp.py] for an example that shows the difference between old style and new style macros and at the [trac:source:tags/trac-0.11/wiki-macros/README macros/README] which provides more insight about the transition. - -=== Macro without arguments - -To test the following code, save it in a `timestamp_sample.py` file located in the TracEnvironment's `plugins/` directory. - -{{{#!python -from datetime import datetime -# Note: since Trac 0.11, datetime objects are used internally - -from genshi.builder import tag - -from trac.util.datefmt import format_datetime, utc -from trac.wiki.macros import WikiMacroBase - -class TimeStampMacro(WikiMacroBase): - """Inserts the current time (in seconds) into the wiki page.""" - - revision = "$Rev$" - url = "$URL$" - - def expand_macro(self, formatter, name, text): - t = datetime.now(utc) - return tag.strong(format_datetime(t, '%c')) -}}} - -=== Macro with arguments - -To test the following code, save it in a `helloworld_sample.py` file located in the TracEnvironment's `plugins/` directory. - -{{{#!python -from genshi.core import Markup - -from trac.wiki.macros import WikiMacroBase - -class HelloWorldMacro(WikiMacroBase): - """Simple HelloWorld macro. - - Note that the name of the class is meaningful: - - it must end with "Macro" - - what comes before "Macro" ends up being the macro name - - The documentation of the class (i.e. what you're reading) - will become the documentation of the macro, as shown by - the !MacroList macro (usually used in the WikiMacros page). - """ - - revision = "$Rev$" - url = "$URL$" - - def expand_macro(self, formatter, name, text, args): - """Return some output that will be displayed in the Wiki content. - - `name` is the actual name of the macro (no surprise, here it'll be - `'HelloWorld'`), - `text` is the text enclosed in parenthesis at the call of the macro. - Note that if there are ''no'' parenthesis (like in, e.g. - [[HelloWorld]]), then `text` is `None`. - `args` are the arguments passed when HelloWorld is called using a - `#!HelloWorld` code block. - """ - return 'Hello World, text = %s, args = %s' % \ - (Markup.escape(text), Markup.escape(repr(args))) - -}}} - -Note that `expand_macro` optionally takes a 4^th^ parameter ''`args`''.
