JavaScript (ECMAScript) and Objective-J runtime
npm install @objj/runtimeObjective-J Runtime
=================
A Node runtime for the [Objective-J][objj] language.
[objj]: http://www.cappuccino-project.org/learn/objective-j.html
It uses an Objective-J to JavaScript [compiler][objj-transpiler] by Martin Carlberg.
[objj-transpiler]: https://github.com/mrcarlberg/ObjJAcornCompiler
Install using npm
``
npm install objj-runtime
Make sure you have grunt commandline installed. If not install with
`
npm install -g grunt-cli
`
Compile and build the runtime with grunt from inside the objj-runtime directory.
`
grunt
Copy a built Cappuccino Foundation framework to the Framework directory. You might need to create the Framework directory inside the objj-runtime directory.
Create an Objective-J main.j file
`
@import
@implementation MyClass : CPObject
- (CPString)myMethod {
return [CPString stringWithFormat:@"Node version: %@", process.version];
}
@end
function main(args, namedArgs)
{
console.log("Hello World");
console.log([[[MyClass alloc] init] myMethod]);
}
`
Compile and run
`
bin/objj main.j
You can debug with the node-inspector and Chrome.
`
node --inspect-brk bin/objj main.j
A framework that is already built can be use if placed inside the Framework directory.
To update the Objective-J runtime you need to copy the files from the Cappuccino Objective-J directory into the Objective-J directory. (This will not work yet as there are some changes to the Objective-J runtime that is not pushed to the Cappuccino project. Should work if you merge in your changes)
Compile and build the runtime with grunt
`
grunt
There are many things that don't work yet. For example you can't just compile your files. You have to compile and run.
Example of very simple backend webserver in Objective-J can be downloaded [here][objj-node-webserver] as a zip file.
[objj-node-webserver]: http://mini.carlberg.org/dev/objj-node-webserver.zip
Start the backend webserver from the command prompt with
`
bin/objj main.j
From another command prompt json data can be stored with:
`
curl 127.0.0.1:1337/Name/42 -d '{"name": "martin"}'
It can be retrieved with:
`
curl 127.0.0.1:1337/Name/42
The url uses a pattern with entity and identifier for storage. It looks like this:
`
curl 127.0.0.1:1337/
