Generate ffi bindings from header files

JavaScript 100.00%

node-ffi-generate's Introduction

npm install -g ffi-generate

Generate FFI Bindings

ffi-generate -f /path/to/myLibrary/header.h -l libmyLibrary

Will parse the given filename and print to standard out the resulting javascript suitable for use as a module.

f -- required -- The header file you wish to parse
l -- required -- The library FFI will use to dlopen
m -- optional -- The module name underwhich functions will be stored (uses library name otherwise)
p -- optional -- Only include functions whose name starts with the provided prefix

you can specify multiple -p on the command line to get multiple prefixes

x -- optional -- Restrict to only functions declared in the given header file
s -- optional -- Use StrictType type wrapper (experimental)
L -- optional -- If libclang.{so,dylib} is in a non-standard path use this which will rerun the process with [DY]LD_LIBRARY_PATH set

It may be necessary to pass additional flags to libclang so it can better parse the header (i.e. include paths). To pass options directly to libclang use -- so ffi-generate-node knows to stop parsing arguments, the rest will be passed to libclang without modification.

ffi-generate -f /usr/include/ImageMagick/wand/MagickWand.h -l libMagickWand -m wand -p Magick -- $(Magick-config --cflags)

Generate FFI Bindings Programatically

var exec = require('child_process').exec;
var path = require('path');
var fs = require('fs');
var jsb = require('beautifyjs');
var generate = require('lib/generateffi').generate;

exec('llvm-config --includedir', function (fail, out, err) {
  var includedir = out.replace(/\s+$/, '');
  var result = exports.generate({
    filename: path.join(includedir, 'clang-c', 'Index.h'),
    library: 'libclang',
    prefix: 'clang_', 
    includes: [includedir],
  });

  if (result.unmapped.length > 0) {
    console.log('----- UNMAPPED FUNCTIONS -----');
    console.log(result.unmapped);
    console.log('----- UNMAPPED FUNCTIONS -----');
  }

  fs.writeFileSync(path.join(__dirname, 'dynamic_clang.js'), jsb.js_beautify(result.serialized));
  var dynamic_clang = require(path.join(__dirname, 'dynamic_clang'));
  var ver = dynamic_clang.libclang.clang_getClangVersion();
  console.log(dynamic_clang.libclang.clang_getCString(ver));
  dynamic_clang.libclang.clang_disposeString(ver)
});

Input to the generate method

opts.filename -- required -- the full path to the header source file to parse
opts.library -- required -- the library ffi should use to dlopen
opts.module -- optional -- the name of the module that will be exported (otherwise uses library name)
opts.prefix -- optional -- restrict imported functions to a given prefix
opts.includes -- optional -- a set of directory paths to aid type expansion
opts.compiler_args -- optional -- a set of clang command line options passed to the parser
opts.single_file -- optional -- restricts functions to only those defined in the header file
- this does not restrict dependent types

The result from generate is an object that has two properties

serialized - a string representation of the bindings suitable for writing to file
unmapped - a set of functions that failed to map -- most likely from failure to map a type to ffi type.

each element is an object with following properties

position - -1 means the return type, otherwise the argument
arg - name of the type that failed to map
name - the name of the function that failed
decl - the signature of the function that failed

node-ffi-generate's Issues

Update clang to version 3.7+

libclang version 3.2 is not available for 64 bit windows. There is only an experimental version for 32 bit windows. Trying to use this gives win32 error 193. This seems to be the reason that windows users are complaining that they're getting the message "Unable to load libclang, make sure you have 3.2 installed...". The earliest version of clang that supports 64 bit windows is version 3.7.

The master branch and v0.0.8 tag have diverged

The package version on master (currently commit 5ad34dc) is v0.0.7, while the published version on npm is v0.0.8.

The v0.0.8 tag has additional MIT license information, but no functional changes.
The master branch has functional changes, but not the MIT license information.

While it's been years, perhaps it'd be best to fix this before a new release.

See

No structs or #defined constants

I'm trying to build FFI defs for nanomsg, but I don't get any struct defs or #define constants, am I meant to be passing magic libclang flags or something?

I have no clue how to debug this further.

Unable to load libclang

I have installed node-ffi-generate on my system for genrating bindings of a dll providing the header file and the library but it throws following error :-
"Unable to load libclang, make sure you have 3.2 installed, either specify -L or
have llvm-config in your path"

My command is > ffi-generate -f PremiereSoftphone.h -l SoftphoneLib.dll

bunch of binding errors

npm ERR! command C:\WINDOWS\system32\cmd.exe /d /s /c node-gyp rebuild
npm ERR! Building the projects in this solution one at a time. To enable parallel build, please add the "-m" switch.
npm ERR! binding.cc

and the list goes on and on with V8 errors

unable to load clang on windows

Despite using the -L option with full path of libclang.dll (and its container folder) it is failing to recognize the clang on Windows.

Can't load libclang on Debian

I got ffi-generate working on my laptop with OS X. It was a bit of a pain, but I was able to confirm that it worked. Now, when I try to do it in Debian I can't for the life of me get it working. I keep getting the "Unable to load libclang, make sure you have 3.2 installed, either specify -L or have llvm-config in your path" error. I would really appreciate some guidance on this. Alternatively, can you update ffi-generate where it downloads libclang automatically so it knows where to find it?

Please respond!

    '  52 | types.["js_CString"] = js_CString;\n' +
    '  53 | types.["js_int32"] = js_int32;'

Looks like it's incorrectly trying to do 'types.' + name or something, where name == '["fuse_args"]' or something.

Issue with arrays of structs inside other structs

Here's a reproducible example:

test.h:

typedef struct fooStruct_
{
    int bar;
} fooStruct;

typedef struct bazStruct_
{
    fooStruct  foos[2];
} bazStruct;

void someFunc(bazStruct* baz);

ffi-generate -f test.h -l foo > foo.js

foo.js:

var FFI = require('ffi'),
    ArrayType = require('ref-array'),
    Struct = require('ref-struct'),
    ref = require('ref');

var voidPtr = ref.refType(ref.types.void);

exports.CONSTANTS = {
};

var fooStruct_ = exports.fooStruct_ = ArrayType(fooStruct_, 2); // this seems broken to me
var fooStruct_Ptr = exports.fooStruct_Ptr = ref.refType(fooStruct_);
var bazStruct = exports.bazStruct = Struct({
  foos: fooStruct_,
});
var bazStructPtr = exports.bazStructPtr = ref.refType(bazStruct);

exports.foo = new FFI.Library('foo', {
  someFunc: [ref.types.void, [
    bazStructPtr,
  ]],
});

node foo.js:

assert.js:92
  throw new assert.AssertionError({
        ^

Pretty awesome

This is pretty neat. Will you still be working on it?

How to set the path of Class

I have a .h file like this

#pragma once 

class  __declspec(dllexport) Person
{
private:
	int age;
public:
	int getAge();
	void setAge(int a);
};

I used this tool to generate it to me like this

var FFI = require('ffi'),
    ArrayType = require('ref-array'),
    Struct = require('ref-struct'),
    ref = require('ref');

var voidPtr = ref.refType(ref.types.void);

exports.CONSTANTS = {
};


exports.libmyLibrary = new FFI.Library('libmyLibrary', {
});

I want to know how to refer to classes and classes that contain a class
