Does anyone know of a CC emu which runs in linux terminal?

I have a cool Poweredge 2950 (and a Windows PC) running Ubuntu, and I want to have it run CraftOS. But the problem is, that every CC emulator runs in the graphical environment and not in the shell.

I want to get a CC emulator that runs within a linux terminal, and can be accessed via SSH client.

Dare I ask why it needs to be accessible via SSH? I just run CCEmuRedux off my USB stick and it works fine.

It might be feasible to port CCLite (or another pure-lua emulator) to use the terminal instead. I wrote a Lua Interop library, which can handle most terminal elements. However, there is no way to get terminal size/cursor position with escape codes, and no way to handle mouse events.

Another suggestion is X11 Forwarding, with something like Xming, but I really don't understand the SSH requirement.

It really would be just a case of rewriting https://github.com/g.../src/render.lua in CCLite to use ncurses. Actually, I might do it…

EDIT: Or not, fount a curses library for lua trough: https://github.com/luaposix/luaposix

CC Emulator that would run in a linux terminal would be brilliant, I would love to have CraftOS technically running on my Raspberry Pi with a TFT screen. Even adding a small portable battery would open up a lot of possibilitys.

I think the easiest way to do this would be to just implement a ssh-like protocol on CC, then running CCEmuRedux or similar headless.

why? i'd easily be able to make a ssh-like system using http(s)

Okay, I suppose SSH wouldn't work, but maybe xterm. Still, if there isn't a terminal-based CC emulator, could someone try porting ccemuredux or cclite? I'm surprised there aren't any text-based CC emus already.

I could try porting Mimic…

actually that might be easy
all there is to it is editing render.js
then putting it in a node/node-webkit instance

well that was easy!
now to make it into a CLI interface

Oh goody! Ooo, is it possible to update the computercraft of Mimic from 1.5 to 1.6?

that'd be up to GS and 1lann, but it supports 1.63:
Features

• Full ComputerCraft emulator in your web browser
• CC 1.63 support
• Mobile (iOS and Android) support

A while ago I wrote a terminal-based emulator: https://github.com/CoderPuppy/cc-emu

I just fixed it up (and added better instructions) when I saw this thread.

Progress update:

I've got it running in node-webkit, which means i can run node-webkit headless or port it to node
see you people tomorrow, i have to go now (GMT - usually 7am-8pmish on sat, if you want to know when you should check if im online)

I was trying to use it, but I think I had a problem with lcurses, and it errors and lists a bunch of missing directories for Lua 5.2. Weird. I am using Lubuntu 14.04.

It is a bit finicky to setup. I think in *buntu you need to install luajit, lua-penlight, lua-curses and lua-posix. If that doesn't work then install luajit then manually compile luarocks with –lua-suffix=jit –with-lua=/usr and use luarocks to install everything else.

Example of using luarocks:

$ wget http://luarocks.org/releases/luarocks-2.2.0.tar.gz
$ tar zxpf luarocks-2.2.0.tar.gz
$ cd luarocks-2.2.0
$ ./configure --lua-suffix=jit --with-lua=/usr
$ sudo make bootstrap
$ sudo luarocks install penlight
$ sudo luarocks install lcurses
$ sudo luarocks install lposix
$ sudo luarocks install luabitop

I get the following error, even after installing the requirements from apt-get:

evan@evan-Latitude-D620:~/cc-emu-master$ lua cli.lua

I think you have to run it with luajit so like luajit cli.lua . (The dot at the end is important, it tells it what directory to use as root)

Edit: also your package.path is weird, it seems to have "?.lua?.lua" or something in it

When I get some sort of linux box running (virtualbox/vagrant doesn't seem to be working on my main computer, i might try my pi) I'll test it out!

$ sudo luarocks install lposix

I tried it out, ./configure fails, lua.h not found

Also, with apt-get commands, lua cannot be found
If I run it with luajit instead of lua, it says that module luarocks.index cannot be found
If I install normal lua5.2, it says module emu not found…

My package.path has ./?.lua in it…
If I remove your editing of package.path, it comes up with the luarocks error again
… even when I apt-get install luarocks

auofyuieguyageufyiufesufys…
… well that is hard….
I have to change every reference of $, window, BrowserFS, XMLHttpRequest etc to node.js equivalents.

I might have to remove everything and just include the lua stuff

if only node webkit supported stdout/in

//require("./scripts/lib/jquery.min.js");
$ = function(x) {return x;};
//require("./scripts/lib/bootstrap.min.js");
//require("./scripts/lib/ace/src-min-noconflict/ace.js")
//require("./scripts/lib/Blob.js");
//require("./scripts/lib/FileSaver.js")

Lua5_1 = require("./scripts/lib/lua5.1.5.min.js")
//require("./scripts/lib/browserfs.js")
require("fs")
require("./scripts/lib/xdRequest.js")
require("./scripts/code.js")
globals = require("./scripts/globals.js")
core = require("./scripts/core.js")
require("./scripts/computer.js")
require("./scripts/filesystem.js")
require("./scripts/render.js")
events = require("./scripts/event.js")
require("./scripts/apis/bit.js")
require("./scripts/apis/fs.js")
require("./scripts/apis/http.js")
require("./scripts/apis/os.js")
require("./scripts/apis/peripheral.js")
require("./scripts/apis/redstone.js")
require("./scripts/apis/term.js")
core.run();

current progress ^

Well… I've done a bit of a rewrite, but I need to implement most (except Date/Time and bit) apis with node.js

It's so exciting, as the load times get longer and longer, while the errors decrease

I think the lua stuff is actually being run :D/>

It gets to fs.list then errors because I haven't implemented the fs api

Also, I have an error which says 'thread' doesn't exist


actually that looks like an error in the Mimic code

corrected, now it's stopping at render.bsod, because I haven't implemented render :D/>

Ok, sorry, I didn't test configure without lua installed, apparently –lua-suffix doesn't do anything (also it appears luajit doesn't include the necessary headers, so maybe that's the problem).

Updated example of using luarocks:

$ sudo apt-get install luajit libluajit-5.1-dev
$ wget http://luarocks.org/releases/luarocks-2.2.0.tar.gz
$ tar zxpf luarocks-2.2.0.tar.gz
$ cd luarocks-2.2.0
$ ./configure --with-lua=/usr --with-lua-include=/usr/include/luajit-2.0
$ sudo make bootstrap
$ sudo luarocks install penlight
$ sudo luarocks install lcurses
$ sudo luarocks install lposix
$ sudo luarocks install luabitop

Good, things are running well, I still haven't implemented most apis but most display stuff works:

that bios error is from lua !!

What version of CC are you using? In 1.7 line 628 is "function()".

don't worry about that, that's just because I haven't implemented (almost) all apis, just testing colors and rendering at the moment
btw its based on mimic, so CC1.63

i have colors people!

You can find the exact colors on the wiki in hex form.

the coloring api i use doesn't support hex values, just a few named colours

comp500 very nice!

Why are you checking in colors.js instead of using npm?

i can't be bothered to make a .gitignore, will exclude it later

oh wait… you found my github repo :D/>

just so other people know, it's at https://github.com/comp500/Mimic

Sorry for doing the same thing as comp500, but I didn't see his work when I started this project. I, too, am porting Mimic to Node.js. I have computer emulation working at https://github.com/Sxw1212/NodeMimic. See the README for details.

Nice! Unfortunately I don't have much time due to school anyway, I'll check out your version!
I can help you add colors just noticed how you do it… complicated but robust :D/> and http.

If nano can capture ctrl, why can't we? Is it in the libraries you're using
http://stackoverflow...-readline-shell < key.ctrl

Wow that's amazing!
Check out my pull request.
I did have to tweak install.js to get it to run on Windows, though

dir = "A:/comp500/Programming/NodeMimic-master/NodeMimic-master/"

Some tips:

• only redraw the screen partially when needed
• worm doesn't seem to work
• on Windows, escape+T/R/S doesn't work

when I overflow the screen (e.g. programs then programs again) it crashes, saying it can't find render

time goes at one day a second

shutdown isn't very clean, leaving you at a blank command prompt and not stopping node

on edit, escape works but when i try to save it gives me a range error byteoffset out of range

We can capture ctrl, but only when another key is pressed, eg nano with Ctrl-X to save. Computercrafts edit just has you press ctrl to access a menu. If you know how to capture the raw ctrl, let me know please.

I haven't implemented esc-t/r/s yet, I'll finish that soon.
As for worm, it's probably not working due to colors being needed.
I've fixed the scrolling, it was a bug from leftover code.
As for the time going at one day a second, that's a Mimic bug. I've opened a Mimic ticket and will upgrade the commit version that's hardcoded when a new stable version come out.
I'll see what I can hook into for the shutdown event.

Thanks for the pull request, I'll look at it in later tonight.
