Arguments checking for NAN module
npm install nan-checkArguments checking in native modules for Node.js
===============================
This project contains some helper utilities that make native addon development a bit more easier.
* Example
* Usage
* API
* Tests
``cpp
NAN_METHOD(calibrationPatternDetect)
{
NanScope();
Local
try
{
if (Nan::Check(info).ArgumentsCount(5)
.Argument(0).IsBuffer().Bind(imageBuffer)
.Argument(1).Bind(patternSize.width)
.Argument(2).Bind(patternSize.height)
.Argument(3).StringEnum
{ "CHESSBOARD", PatternType::CHESSBOARD },
{ "CIRCLES_GRID", PatternType::CIRCLES_GRID },
{ "ACIRCLES_GRID", PatternType::ACIRCLES_GRID } }).Bind(pattern)
.Argument(4).IsFunction().Bind(callback))
{
Nan::Callback *nanCallback = new Nan::Callback(callback);
Nan::AsyncQueueWorker(new DetectPatternTask(imageBuffer, patternSize, pattern, nanCallback));
Nan::ReturnValue(Nan::True());
}
Nan::ReturnValue(Nan::False());
}
catch (Nan::CheckException& exc)
{
return Nan::ThrowTypeError(exc.what());
}
}
`
Simply add NAN-Check as a dependency in the package.json of your Node addon:
` bash`
$ npm install --save nan nan-check
Pull in the path to NAN and NAN-Check in your binding.gyp so that you can use in your .cpp files:
` python`
"include_dirs" : [
" "]
This works like a -I when compiling your addon.
TODO: Write
To run the NAN-Check tests do:
` sh`
npm install
npm run-script rebuild-tests
npm test
Or just:
` sh``
npm install
make test
