Graphic Editor for C Language Using Blockly.

[정인호]

Hi, we are a team which trying to implement graphical editor for C language using blockly.

Although we are very passionated to this, but as we are all students and has few knowledge and skills for this, accomplishment seems to be very difficult.

If any person who has experience with implementing new language on blockly can give some suggestion or insights, it gonna be a big assistance to us.

i'd imagine since blockly compiles to javascript code, all you'd have to do is run the javascript output through a library that compiles javascript to c code

I have been working on building Java Support for Blockly.

https://github.com/TechplexEngineer/EasyJ4FRC

In the generators folder you need a new <language>.js and a folder named <language> IE: "c.js" and "c"

Then in the apps folder you can make a new app or modify an existing one.

You'll find that many of the existing apps use soy templates to handle multiple languages. Templates and languages was not something I had the manpower to accomplish, so I followed the template of the block factory as being a simple way to generate code. My first attempt was this dubbed FRCJava. Then I needed more IDE like features, those are here, dubbed Robotbuilder. Id recommend trying not to make changes to the Blockly core files. Instead with JavaScript it is easy to include an override for the method which needs changing. Here is an example of overriding the flyout/toolbox filter method, to allow disabling of blocks which require other blocks before they can be added.

Good Luck!

Do post where you'll be hosting the repository (I'd recommend Github) I would like to see a c version of blockly.

The team behind Zero Robotics created a Blockly application that generates code in C++. While it isn't perfect for what you need, it could be a good starting point.

FYI, that implementation also includes some fairly heavy modifications
to the core files, some of which are related to C strong typing and
some to fitting Blockly into our specific application. For the more
C-related bits, check the generator folder, blocks/variables.js,
core/variables.js, core/procedures.js, core/blocks.js, and
core/field_variable.js. You can check out the application in
production at zerorobotics.mit.edu.

Thanks for the advice, Blake. :)

I'll try following your procedure to get thing done or not.

May I contact you? If you would like provide more detailed information, it'll be huge help to us.

BTW, we are using GitHub as our SVCS. :)
