Wisitoken is a general purpose parser; it can be used for any language.

The ELPA wisi package provides elisp code to provide indentation,
font-lock, and navigation facilities using a parser, and the subset of the
wisitoken Ada code to implement the language-independent part of that;
the parser generator, the parser runtime with error correction and
indentation, font-lock, and navigation actions to add in a language

The ELPA wisi package also provides integration with Emacs project.el
and xref.el, with dispatching for language-specific parts.

The ELPA ada-mode package provides the Ada grammar definition file, and Ada
code implementing the Ada-specific parts of the grammar actions.

The ELPA ada-mode package also provides the GPR-specific things for gpr-mode.

The ELPA wisitoken-grammar-mode package provides the WY-specific things
for wisitoken-grammar-mode (for editing wisitoken *.wy files).

I have unpublished Java and Python modes that use wisi. It turns out
Java is not well suited to LR parsing, at least using the grammar from
the language reference directly. I don't know what the Oracle
parser does. Eventually I hope other language modes will use wisi.
