Thorough redesign of the Bindat system, which makes it possible to define new Bindat type forms, define recursive types, control the values returned when unpacking, freely mix arbitrary computations with type definitions, as well as support for arbitrary sized integers. This also reverts the recent addition of the `bindat-spec` macro and the support for 64bit integers in the old Bindat language since that is now considered obsolete anyway. * doc/lispref/processes.texi (Bindat Types): Rename from `Bindat Spec` and rewrite for the new sublanguage. (Bindat Functions): Adjust to the new terminology. (Bindat Computed Types): New node. * lisp/emacs-lisp/bindat.el (bindat--type): New type. (bindat--unpack-u64, bindat--unpack-u64r): Delete functions. (bindat--unpack-item, bindat--pack-item, bindat--fixed-length-alist): Revert addition of support for 64bit integers. (bindat--unpack-group, bindat--length-group, bindat--pack-group): Handle the new `bindat--type` values. (bindat-spec): Revert addition of this macro. (bindat--unpack-uint, bindat--unpack-uintr, bindat--pack-uint) (bindat--pack-uintr): New functions. (bindat-type, bindat-defmacro, bindat--pcase): New macros. (bindat-type): New Edebug elem. (bindat--type): New generic function. (bindat--primitives): New constant. (bindat--macroenv, bindat--op): New vars. (bindat--make-docstring, bindat--fun, bindat--makefun, bindat--toplevel): New functions. * test/lisp/emacs-lisp/bindat-tests.el: Use `bindat-type`. (ip): New Bindat type. (header-bindat-spec, data-bindat-spec, packet-bindat-spec): Adjust to new `bindat-type` macro. (bindat-test-unpack): Simplify now that the order of fields is preserved. (bindat-test--int-websocket-type, bindat-test--LEB128): New consts. (bindat-test--pack-val, bindat-test--sint, bindat-test--recursive): New tests. |
