Detailed Description

A regular expression compiler.

Constructor & Destructor Documentation

def __init__

(

self

)

Construct compiler for OpenFst format (the default) transducers.

def __init__	(		self,
			impl
	)

Create compiler for impl format transducers.

Member Function Documentation

def compile	(		self,
			xre
	)

Compile a transducer defined by xre.

May return a pointer to empty transducer on non-fatal error. A None pointer is returned on fatal error, if abort is not called.

Returns

An HfstTransducer pointer.

def define_function	(		self,
			name,
			arguments,
			xre
	)

todo

def define_list	(		self,
			name,
			symbol_list
	)

todo

def define_transducer	(		self,
			name,
			transducer
	)

Add a definition macro.

Compiler will replace arcs labeled name with a transducer transducer in later phases of compilation (if set_expand_definitions(True) has been called).

def define_xre	(		self,
			name,
			xre
	)

Add a definition macro.

Compiler will replace arcs labeled name with a transducer defined by regular expression xre in later phases of compilation (if set_expand_definitions(True) has been called).

def getOutputToConsole

(

self

)

(Windows-specific) Whether output is printed to console instead of standard output.

def is_definition	(		self,
			name
	)

Whether name is a definition.

def is_function_definition	(		self,
			name
	)

Whether name is a function definition.

def set_expand_definitions	(		self,
			v
	)

Whether definitions are expanded.

• v True or False

def set_verbosity	(		self,
			v
	)

Set the verbosity of the compiler.

• v True or False

def setOutputToConsole	(		self,
			v
	)

(Windows-specific) Whether output is printed to console instead of standard output.

• v True or False

def undefine	(		self,
			name
	)
