NYACC, for Not Yet Another Compiler Compiler, is set of guile modules for
generating parsers and lexical analyzers. It also provides sample parsers
and pretty-printers using SXML trees as an intermediate representation.
It provides a decent C parser and a `FFI Helper' tool to help create
Guile Scheme bindings for C-based libraries.
It provides (partially implemented) compilers based on above mentioned
parsers to allow execution with Guile as extension languages.
Updates for 3.02.0 from 3.01.1
* Many thanks to #lechner for persistence in testing new commits!
* Updated ffi-helper to allow other backends (e.g, bstruct,
bytestructures). See github.com/mwette/guile-fhbe. This was
accomplished by adding a layer of indirection for low-level
type construction.
+ Compile time for gtk2.ffi is 5% longer.
+ Compiled ffi modules include case-backend syntax form.
(See ffi/cairo.ffi for an example use case.)
* Moved ffi-help-cd.scm back to ffi-help.cd, like for v1.0.
* In cdata, removed support for previously deprecated types (e.g.,
"signed long int") in preference for canonical short names (e.g.,
"long"), as parse-c99 does not produce them.
* Merged "powerpc64le" machine arch (from #gwitmond) into
arch-info.
* Added s390x machine arch (thanks #rlb) into arch-info. issue#27
* In cdata, exposed procedure make-cdata/* which will create
an object from a pointer.
* The cdata user guide has been reviewed and expanded.
* cdata-ref now returns scheme array and struct values as Guile
objects (array and alist). To get cdata objects, use cdata-sel.
* cdata-set! now accepts scheme arrays (and vectors) for carray and
alists for cstructs and cunions.
* Fixes issue#22: buggy cdata-ref/set! with anonymous
struct/unions.
* Fixes issue#24: c99 parsing empty-structs (struct { };).
* Fixes issue#25: attribute arguments w/ math expressions.
* Fixes issue#26: __u32 not found => major bug in process-decls
0cc90f6
* Fixes issue#49: use asm-based link name for foreign-pointers
* Worked more on the "mlang" language example parser and analyzer.
* In define-ffi-module identifier ffi-arch is available march.
NYACC maturity is production/stable level.
