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.
NEWS for V1.05.0
* remove dependence on srfi-43, vector operations; this was
causing issues with some Guile versions 2.0.X
* cleaned up c99-error exception messages in compile-ffi
* examples/ffi/termios.ffi: added def-keepers
* in following, $ENL = examples/nyacc/lang
* removed $ENL/ecmascript
* $ENL/javascript: merged body.scm into parser.scm
* install/uninstall read-line-code now returns #<unspecified>
* $ENL/tcl/parser.scm: fixed reading array index as number;
(1,2,3) was read as number, now as string
* scripts/compile-ffi: add option -s to show includes being read
* c99 parser def-help now adds apple dependencies
* worked on ffi-helper per-decl usage (i.e. C-decl syntax)
* updated "make check" to provide overall sucess/fail message
Example using FFI helper w/o define-ffi-module:
mwette$ guile
...
scheme@(guile-user)> ,use (nyacc lang c99 ffi-help)
scheme@(guile-user)> ,pp (C-decl->scm "struct foo { int x; double y; };")
$1 = (bs:struct (list `(x ,int) `(y ,double)))
scheme@(guile-user)>
scheme@(guile-user)> ,use (bytestructures guile)
scheme@(guile-user)> ,use (system ffi-help-rt)
scheme@(guile-user)> (use-modules ((system foreign) #:prefix ffi:))
scheme@(guile-user)>
scheme@(guile-user)> (define struct-foo-desc
(C-decl "struct foo { int x; double y; };"))
scheme@(guile-user)> (define-fh-compound-type struct-foo
struct-foo-desc struct-foo? make-struct-foo)
scheme@(guile-user)> (make-struct-foo)
$2 = #<struct-foo 0x7f61394d7d40>
scheme@(guile-user)>
scheme@(guile-user)> (define my-sqrt (C-decl "double sqrt(double);"))
scheme@(guile-user)> (my-sqrt 4.0)
$3 = 2.0
scheme@(guile-user)>
mwette$ guile
...
scheme@(guile-user)> ,use (nyacc lang c99 ffi-help)
scheme@(guile-user)> ,d load-include-file
- Procedure: load-include-file filename [#:pkg-config pkg]
This is the functionality that Ludo was asking for: to be at guile
prompt and be able to issue
(use-modules (nyacc lang c99 ffi-help))
(load-include-file "cairo.h" #:pkg-config "cairo")
scheme@(guile-user)> (load-include-file "cairo.h" #:pkg-config "cairo")
