Tell me what you think ;)

Afaik my's last' name is equivalent to

my.name['last']

How does the ' operator decide between need for 's and not?

Where is the GitHub page? :-) What did you learn :-) Who are you ?

Nice one

It doesn't care basically if it's encountering a dict ({}), an object, or a function/method.

If it's not a function then it's either a dict OR another object instance. it it's a function it applies it! Glas treats everything as potential functions or procedures (no arguments) math sin: x could be _anything_ really :)

Use '$' sign if you wish to refer to function's object explicitly like this:

    a function name # could be application?
    $ a function name # definitely function object to be referred!

Ah! Yes! :)

I had some kind of a satori Saturday, so it's still just a glas.py file which aims are being a simple as possible translator into Python. (for now it just parses it and evals it like a barbarian, and still not workable ;))

I will make a repo later today, after work.

Just like Python, Glas (Глас) doesn't really distinguish between dicts, objects or methods/functions. For it functions are just a fancier version of objects which are a fancier version of normal dicts. Later on, during evaluation, Glas makes a distinction, not before though.

I am planning on adding additional features like adding statements after each method call with the ':' operator, like this:

    # ship.attach_weapons(...):

    ship's attach weapons: blasters, rockets, lasers:
        print "Eeeekkrrrrgh! Weapons attached successfully!"
        print "listing:"
        for weapon in *: #all arguments of attach weapons
             print "Weapon:", weapon
    else:
        print "WARNING! WARNING! Ship weaponry attachment FAILED"
        print "You're defenseless!"

    detach weapons:' ship:
        print "Weaponry detached, seek cover!"
    else:
        print "Weaponry detachment FAILED!"
        print "  AUTODESTRUCT SEQ. INITIATED"
        print "  EJECT EJECT EJECT!"
        auto destruct: 20s' ship

Nevermind that, listen to this:

    nevermind: that --> listen: this ~ to
    # nevermind(that).listen(this.to)

    # All you do is complain and whine to your boss,
    #  slacking, sipping a lot of coffee at the coffeeshop:
    complain: and whine -> my ~ boss -> slack: sip coffee: a lot --> coffeeshop
    # my.boss.complain(and_whine).slack(
    #      coffeeshop.sip_coffee(a_lot)
    #    )
    
    foo: normal dict['some key'] -> bar

;)

If you find '.' and ''' and ''s' offending, you can change the symbol to the old dot and "@" for instance.

and that's much better than that.much better, don't you think?

    cookie adventure: my @ Cookie Monster = 
        print "Cookie Monster, why is the Cookie jar empty?"
        why: my.cookie.jar.empty: @ cookie monster 

        # why cookie monster, why? :)
        why: my.cookie.jar.empty: @ cookie monster .why: "tell me!"

New ROCKING syntax!

    #!/usr/bin/env glas
    #
    # Yay, and hear these spoken words of wisdom, Stranger:
    #
        and: he ~ walked: through the valley ~ 
                valley + shadows & 
                valley + shadows + death --> 
                    and: he ~ feared: not: evil
    #
    # versus the barbaric cries of the past!
    #
    #! old pythonic
    #
        and( 
            he.walked( through_the_valley.combine(
                [valley, shadows], [valley, shadows, death] )
        ).and( he.feared(not(evil)) )

Now you can use the familiar

    do something: a dict ['some key'], coordinates['x']

    a space adventure = space ship, blasters, rockets, lasers, *, **:  -> Space Ship:
        space ship ~ attach weapons: blasters, rockets, lasers:
            {{ "Eeeekkrrrrgh! Weapons attached successfully!" }}
            {{ "listing:" }}
            for weapon in *: #all arguments of attach weapons
                 {{ "Weapon:", weapon }}
        else:
            {{ "WARNING! WARNING! Ship weaponry attachment FAILED }}
            {{ "You're defenseless!" }}

        detach weapons: -> space ship:
            {{ "Weaponry detached, seek cover!" }}
        else:
            {{ "Weaponry detachment FAILED!" }}
            {{ \t, "AUTODESTRUCT SEQ. INITIATED" }}
            {{ \t, "EJECT EJECT EJECT!" }}
            auto destruct: 20s -> space ship

bhdz12• 13 years ago

Ah yes!

    {{ \t, "eject eject eject!" }}
    auto destruct: 20s -> space ship
    {> user ejected % wait: 20s, any -> input <}

    {{ "Your ship explodes in a gigantic fireball!" }}

    if: empty: -> input ->> user ejected
        {{ "You fail to eject, Ouch!" }}
        space ship ~ pilot ~ die: "massive splosion"
    space ship ~ destruct: "massive splosion"

Glas doesn't care about keywords actually, the only "keywords" are the syntactic elements like ~ -> ->> { [ {{ {> <}

so you write:

    if: something ~ happened: and: something else ~ happened:
        logic ~ did: something ~ happened # ?

and

    for: x in: range: 12, 32
        {{ x }}

this chains the needed things nicely in fact you can write like this:

    in: range: 5, 13
        perform: a task

    for: x in: iter: person
        {{ x }}

In fact, the symbols that form the syntax, doesn't matter at

all: standard symbol set:

    ~  # access, forward (standard)
    object ~ property
    -> # access, backward ("homosexual" call if you will)
    method -> object
    ->> # access, backward high ("homosexual" call with higher precedence than ~ and ->... very gay...)
    some ~ linkage ~ method ->> object
    <- # backcall semantics, normal precedence, "tailored" calling
    "eenie", "meeenie", "minie", "moe" <- count toes:
    take: basket: "apples", "oranges", "bananas" <<- fill basket:
    # take(basket().fill_basket("apples",...), ...)
    # BE CAREFUL with that code above
    # basket doesn't get created with the fruits, just empty basket which 
    # is subsequently filled with goodies

All these operators can be a different set, but these glyphs are the best in my opinion

~ # PS: PLEASE do NOT get offended by my characterization

# of certain method calls as "homosexual"

# Don't! This is just for laughs at the language

# I am not against gay community in any way

# and "homosexual" calls are actually the most

# useful feature of this language

# Thank you.
