The taglib module is loaded implicitly and supports Active Tags functionality. The taglib module provides the following methods:
- load( libname, [libfrom], [libas] ):
Loads a tag library class named libname from a file called libfrom in the search path, and installed it under the tag prefix libas. The default for libfrom is libname.py. The default for libas is libname. Once installed, a library name is its unique tag prefix. - unload( libname ):
Unload a tag library that is installed under the libname prefix. This is usually performed only at the end of a request. - tagPush( libname, tagname, pair ):
Push a new tag object for a libname:tagname tag onto the tag stack. The pair parameter is a flag indicating whether this is a singleton or a paired tag. - tagPop():
Pop the current tag from the tag stack. - getTag():
Return the current tag object. - outPush():
Begin capturing the current output stream. This is usually called by the tagBegin method. - outPopCond():
End capturing the current output stream, and return the captured contents. It will only "pop" once, even if called multiple times for the same tag. This method is usually called by either the tagEnd(), tagCatch, or tagPop() methods. - tagBegin( attrs ):
This method sets the tag output and variable environment, and then calls the tag's begin() method with the given attrs tag attribute dictionary. This method returns a flag, and the tag body must be processed if and only if this flag is true. - tagBody():
This method sets the tag output and variable environment, and then calls the tag's body() method with the captured output of the body processing. If this method returns true, then the processing of the body must be repeated. - tagEnd():
This method sets the tag output and variable environment, and then calls the tag's end() method. This method must be called if the tagBegin() method completes successfully in order to preserve tag semantics. - tagCatch():
This method should be called if any of the tagBegin, tagBody or tagEnd methods raise an exception. It calls the tag's catch() method with the current exception.
