FRISCjs
=======
FRISCjs is a [FRISC processor](http://www.fer.hr/rasip/knjige/frisc) simulator written in JavaScript.
The FRISCjs simulator has two parts: a [FRISC assembler](src/friscasm.peg) (built using PEGjs) which translates FRISC assembly code to machine code and a [FRISC CPU simulator](src/friscsim.js) which executes machine code.
Furthermore, there are two user interfaces to the simulator: a [Web application graphical interface](webapp/index.html) and a [NodeJS command-line interface](consoleapp/frisc-console.js).
The Web application interface is available [here](http://izuzak.github.com/FRISCjs/webapp/) and supports many cool features like breakpoints and step-by-step execution.
## Usage
### Using the assembler and simulator libraries
In node, install using npm:
> npm install friscjs
and then access the assembler and simulator:
var friscjs = require("friscjs");
var asm = friscjs.assembler;
var sim = friscjs.simulator;
In a browser, link to the browser script that contains both the assembler and simulator:
and then access the assembler and simulator:
var asm = friscjs.assembler;
var sim = friscjs.simulator;
After installing the libraries, check out the [FRISCjs API docs](API.markdown) for instructions on using them.
### Using the simulator console and Web applications
To use the Web-based simulator, launch the `webapp/index.html` page in a browser or access the on-line version at [http://izuzak.github.com/FRISCjs/webapp/](https://izuzak.github.com/FRISCjs/webapp/).
To use the console-based simulator application, clone the FRISCjs repo:
> git clone https://github.com/izuzak/FRISCjs.git
and then run the app with node to see the instructions:
> node ./consoleapp/frisc-console.js
## Development
1. Fork and/or clone repo: `git clone https://github.com/izuzak/FRISCjs.git`
2. Change dir to noam: `cd FRISCjs`
3. Install dependencies: `npm install`
4. Make changes to noam sources (`./src`), tests (`./tests`) or apps (`./webapp/*` and `./consoleapp/*`)
5. Build using grunt: `grunt` (on linux), `grunt.cmd` (on windows)
6. Run tests: `npm test`
7. Fix issues reported by grunt and tests, and then repeat 5)
8. Commit, push and make a pull request, or send a git patch by e-mail
9. E-mail me if you have questions (e-mail address is below)

This project was inspired by the [GameBoy emulator in JavaScript](http://imrannazar.com/GameBoy-Emulation-in-JavaScript:-The-CPU) and [jsLinux](http://bellard.org/jslinux/tech.html) projects.
There are many other processor simulators in JavaScript, such as the [GameBoy Color emulator](https://github.com/grantgalitz/GameBoy-Online), [visual transistor-level simulation of the 6502 CPU](http://www.visual6502.org/JSSim/expert.html), [6502 compatible assembler and emulator](http://www.6502asm.com/) and this [other 6502 CPU simulator](http://skilldrick.github.com/easy6502/).

FRISCjs was developed by [Ivan Zuzak](http://ivanzuzak.info). Contributors: [Ivan Budiselic](https://github.com/ibudiselic), [Stanko Krtalic](https://github.com/Stankec).
FRISCjs is built with many open-source projects:
* [PegJS](https://github.com/dmajda/pegjs) - used for generating the FRISC assembly code parser.
* [NodeJS](https://github.com/joyent/node) - used for the command-line version of the simulator.
* [jQuery](http://jquery.com) - used for the Web application version of the simulator.
* [Bootstrap](http://twitter.github.com/bootstrap) - used for the Web application version of the simulator.
* [Ace](http://ace.ajax.org/) - used as the editor for the Web application version of the simulator.
* [Mustache](https://github.com/janl/mustache.js/) - used for client-side templates.
* [Keymaster](https://github.com/madrobby/keymaster) - used for reconfiguring/disabling keyboard shortcuts.
