Toy Parser Generator is a lexical and syntactic parser generator for Python.
|
|
This generator was born from a simple statement: YACC is to complex to use
|
|
in simple cases (calculators, configuration files, small programming
|
|
languages, ...).
|
|
|
|
TPG can very simply write parsers that are usefull for most every day needs
|
|
(even if it can't make your coffee). With a very clear and simple syntax, you
|
|
can write an attributed grammar that is translated into a recursive descendant
|
|
parser. TPG generated code is very closed to the original grammar. This means
|
|
that the parser works "like" the grammar. A grammar rule can be seen as a
|
|
method of the parser class, symbols as method calls, attributes as method
|
|
parameters and semantic values as return values. You can also add Python code
|
|
directly into grammar rules and build abstract syntax trees while parsing.
