What is you first favorite?

Go. Go is by far the best programming language I have ever used, too bad its no good for this kind of thing.

For scripting I prefer JavaScript so long as it is not complicated, once you start getting complicated in JavaScript it becomes pretty hard to work with.

For least favorite launguages: (in least favorite first order)
Python
Forth
Most BASICs
lua
Java
C
C++

Most other languages are somewhere after lua/C. As far as embeded scripting launguages go there are not many (if any) good choices, JavaScript is about the best (as long as you dont try to be too OO)

Duha,

I think it's worth adding tutorial anyway - at the end of the day, if people want to use coffeescript and that results in more AIs or warzone mods, it's good for the community despite the ugly syntax

Spoiler:

1.copy coffe-script.js to game folder

2. in you code

Code: Select all

include('multiplay/skirmish/load_api.js'); // include loader

3. multiplay/skirmish/load_api.js // I generate it via script

Code: Select all

function api() {}; // Main container
include('multiplay/skirmish/coffee-script.js');
api.CoffeeScript = CoffeeScript;
this.CoffeeScript = null; # dont need it in savegame
try {
    include('multiplay/skirmish/api/inspector.js'); 
    api.CoffeeScript.eval(inspectorCoffee); 
    } catch (error) {
        debug("Fail to eval script <inspector.coffee>: " + error);
}
}

4. converting coffee to js via python script. I convert it to text var and evaluate it via Coffescript.

Code: Select all

#python(2.7)
import os
from glob import glob

PATH = 'g:/Games/Warzone 2100-3.1_rc3/mp/multiplay/skirmish/'
MOD_NAME = 'api'
SCRIPTPATH = os.path.dirname(__file__)
separator ='\\n\\'

dir = os.path.join(PATH, MOD_NAME)
if not os.path.exists(dir):
    os.mkdir(dir)

files =  glob('%s/*.coffee' % SCRIPTPATH)
file_names = {os.path.basename(file).replace('.coffee', ''):file for file in files}

def add_to_loader(load, name):
    load.extend([
            'try {',
            "    include('multiplay/skirmish/%s/%s.js');" % (MOD_NAME, name),
            "    api.CoffeeScript.eval(%sCoffee);" % name,
            '    } catch (error) {',
            '        debug("Fail to eval script <%s.coffee>: " + error);' % name,
            '}',  ''
            ])

def create_loader(groups):
    start = [
        'function %s() {}; // Main container' % MOD_NAME,
        "include('multiplay/skirmish/coffee-script.js');",
        'api.CoffeeScript = CoffeeScript;',
        'this.CoffeeScript = null;',
        '',
        ]
    middle,end  = [], []

    names = file_names.keys()

    for key in groups['start']:
        if key in names:
            add_to_loader(start, key)
            names.remove(key)

    for key in groups['end'][::-1]:
        if key in names:
            add_to_loader(end, key)
            names.remove(key)

    for name in names:
       add_to_loader(middle, name)

    with open(os.path.join(PATH, 'load_%s.js' % MOD_NAME),  'w') as f:
        f.write('\n'.join(start + middle + end))


def write_files():
    for name, file in file_names.items():
        with open(os.path.join(PATH, MOD_NAME, '%s.js' % name), 'w') as f:
            lines = open(file).readlines()
            lines = [line.rstrip('\n\r').replace("'", "\\'") for line in lines]
            start = "%sCoffee = '%s" % (name, separator)
            end = "'"
            new_lines = [start] + ['%s%s' % (line, separator) for line in lines if line] + [end]
            res = '\n'.join(new_lines)
            f.write(res)


# set order here
groups = {'start':  ['inspector'],
          'end': [] # last element of list will be loaded last!
}

create_loader(groups)
write_files()

ECMAscript to get fat arrows similar to coffeescript? http://javascriptweblog.wordpress.com/2 ... -fat-city/
