I doubt it. It's not absolute bleeding edge, but it's pretty new.
I was going to include the whole thing I'm trying to test, but expect that
to fail so here's a super simple test
https://github.com/d3x0r/test-accessor
It sets a SetAccessor called 'text' and a SetNativeDataProperty called
'native'
to build
npm install .
test1 : ( only setter called is SetAccessor settter )
npm test
(sample output)
> node test.js
plugin.cc: getter called... default value
Default: default value
plugin.cc: setter called... with newText
plugin.cc: getter called... newText
Default: [] newText
plugin.cc: getter called... newText
Default: newText
Default: [ 'native' ] nativeText
test2 : (passes --disable-old-api-accessors which makes neither setter get
called )
npm run test2
(sample output)
> node --disable-old-api-accessors test.js
plugin.cc: getter called... default value
Default: default value
Default: [ 'text' ] newText
plugin.cc: getter called... default value
Default: default value
Default: [ 'text', 'native' ] nativeText
--------- what I would have sent ---------
This is a node plugin - https://github.com/d3x0r/sack.vfs the new features
I'm extending it with I can only confirm work under Windows.
https://github.com/d3x0r/sack.vfs/blob/master/src/gui/sack_psi_module.cc#L415
configures accessor on prototype here
Which is tested with this
line... https://github.com/d3x0r/sack.vfs/blob/master/tests/sack_test4.js#L28
which should change the text in the resulting gui.
