Intentions

In an effort to conceptualize a programming course for beginning minors and children, it became clear in early tests that fast visual feedback is the best motivation. Development basics like low level networking and direct file access are not possible in the browser. Back in the days an editor and a compiler would be enough to start out with simple command line programs and standard input/output. Bringing basics of web development to beginners involves at least three languages: HTML, CSS, Javascript. Too much overhead to draw a line on the screen. So while maintainig a feature rich foundation for graphical scripting, it is supposed to be the base for a simplified gfx programming abstraction, suitable for children and minors, with abilities to exchange cross platform compatible scripts.

The Rough Roadmap

Get a JS test suite up and running to stabilize API early on
More GL features!
Add a usefull 2D REPL console
Security features (like user dialogues for file and network access etc.)
Allow remote resource loading (http://mydomain.org/index.cjs, certificates, user trusted domains, domain specific contexts)
Native modules (dynamically load additional bindings)
Multi Window/Display support

Run

OSX

Drag a js file onto the application. If it is a cinder module, it will run it. If another script is already running, it is shut down and replaced.
Or, simply specify a "*.js" file to run on startup:

$> open xcode/build/Debug/cinderjs.app --args /examples/cube/cubes.js

Hotkeys

ESC 2x
Hitting ESC two times fast will first exit fullscreen mode and if not in fullscreen mode, it will quit and terminate the application completely.
F1
Toggle FPS text, showing the current Cinder & v8 frame rate.
F2
Toggle v8 heap statistics.
F3
Toggle textual console overlay.

Build & Develop

Checkout the git submodules with:

$> git submodule init
$> git submodule update

Then build v8 (make x64.debug || x64.release) and Cinder (./xcode/fullbuild.sh). After that the xcode cinderjs project should build as alls paths are relative.

v8

Using Version 4.7.3

Get depot_tools and add to your PATH:

git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
export PATH=`pwd`/depot_tools:"$PATH"

Then run

fetch v8
cd v8
git checkout 4.7.3
gclient sync
make x64.debug

To be able to debug JIT code, build v8 with the compiler flag "gdbjit=on". For detailed build instructions have a look at the Google V8 build docs.

To be able to link against libc++ with clang, build on OSX with:

export GYP_DEFINES="clang=1 host_clang=1 use_custom_libcxx=1 mac_deployment_target=10.10 clang_dir=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr"

Make example using 8 parallel build processes:

make -j8 -e x64.debug

Cinder

To avoid building all the libs within "fullbuild.sh":

xcrun xcodebuild -project Cinder/xcode/cinder.xcodeproj -target cinder -configuration Debug
