OpenZz

OpenZz is an interpreted dynamic parser which is well-suited to rapid development of parsing solutions, starting from rapid language prototyping to full-fledged compilers. OpenZz is a dynamic LALR(1) parser which allows its grammar to be modified and extended by commands written in its own language as well as through functionality provided by external libraries. It is implemented as a C library and exports C-bindings, so it can be joined with other code libraries both by static linking and runtime module loading.

    Release Notes: The syntax 'when delete scope' is now available, and may be used to remove lexical data types (tags) when syntax types get out of scope. It is necessary to allow type redefinition. Three new functions were added: zz_get_error_number(), zz_get_param_stack_depth(), and zz_lex_remove_tag(). The function zz_lex_add_new_tag was changed. The dynamic lib extentions ABI was changed, and loading is now fixed. Now the init function is named zz_ext_init(). A bug present in gcc-2.96-98 compiling avl.c was worked around.
