tinyap

Tinyap is a unique software tool that serves as an abstract and adaptive recursive parser, catering to both C and Java. Unlike other parsers, Tinyap is designed to take any text and an accompanying AST grammar as inputs and generate an output that describes the essential content of the text according to the given grammar.

The best part about Tinyap is its ability to simplify the development of new programming languages, thereby facilitating the corresponding interpreters or compilers through the creation of a single tool for parsing the source grammar and the text. The parser comes equipped with two built-in grammar forms suitable for parsing any LL(k) language.

Originally developed in C, Tinyap supports C++ and Java via the JNI. However, the C++ and Java API systems are currently discontinued, barring specific requests. The tool can be installed by following simple steps, such as accessing the source code directory, running './configure' to configure the package for the system, following up with 'make' to compile the package, optionally running 'make check' to authenticate self-tests, and installing all necessary files and documentation with 'make install.'

Tinyap also comes with various options for its usage, including choosing input and output files, selecting a grammar to parse, parsing the input text, using output AST as a new grammar, or walking the current output tree with their named ape. Notably, this latest version of Tinyap also supports AST "unparsing," a feature that allows the user to reverse parse AST back to text uniformly with support for formatting.

In conclusion, Tinyap is indeed an advanced software tool that offers immense support for parsing programming languages with ease and efficiency.
