nyu is a combination of modern academic approaches to parsing formal grammars from PEGs and expression grammars that represents the new state of the art in parser generators. nyu grammars are written in a powerful language based on PEGs (parsing expression grammars) but with modifications to allow both the AST and the parser to be specified intuitively in a single grammar. nyu outputs parsers that take advantage of the chilon::parser meta-programming library for C++. The generated parsers are almost as concise and readable as the input grammars, yet perform as well as hand-written C code. nyu ASTs are built using tuples, variant types, and lists, and allow self referential parsers and AST nodes to be manipulated. Advanced features such as hashed containers and grammar inheritance are also possible and well tested. nyu is currently powerful enough to deal with complex grammars and bootstraps its own parser.
Ezphpconfig generates a set of PHP configuration classes from a supplied XML file. You can then access your configuration values very quickly without having to parse the XML file on every request. The element (tag) names become property names and the text contained in the elements becomes the property's value. It also supports nested elements. If the generated PHP file is older than the XML file, it is re-generated using the data in the newer XML file. This class also supports array types using the element inside an element whose type attribute is set to "array".
pyPEG is a quick and easy solution for creating a parser in Python programs. pyPEG uses a PEG language in Python data structures to parse, so it can be used dynamically to parse nearly every context free language. The output is a plain Python data structure called pyAST, or, as an alternative, XML.
Dexter is a tool that allows users to define extended attributes which can be associated with descriptors and editors. These attributes can be embedded into any well-formed XML document. The resulting embellished document, the 'source', is then input to the dexter engine. This will generate one or more XSLT stylesheets describing the input document interpolating editor modifications and any instructions specified by the descriptors. As dexter's operations are specified exclusively with extended attributes, all but the most unforgiving of XML content viewers will continue to see the decorated source exactly as the designer saw it before.
