~ATH interpreter (it works!)(feedback requested)

[humbleElitist]

hey.
I wrote a ~ATH interpreter.

Its still in the early stages, but it works.

It is written in python, so you will need python to run it.

https://github.com/drocta/TILDE-ATH

I intend to work on it more later, but it is in a working state.

I believe It is Turing complete.

Although, most algorithms in it will probably use a lot more memory than they would in other things.

Here's hoping everyone likes it.

(Includes a clear description of syntax)

This is pretty neat. I'd play around with it, but the computer I'm using doesn't have Python.

[razorknight]

This is pretty interesting, but... which version of python is this?

I'm using 3.2.3 and there is a syntax error. I'll try and see if I can fix any errors I find so that it can run in 3.2.3, but...

[humbleElitist]

I think it's 2.7 .

I believe the two problems you will have are the print command and the raw_input.
Changing all instances of print blah to print(blah)
And changing the raw_input to
I think it's input
Should work.

I think I'm using 2.7
I'll make sure when I get home.
I can probably put a 3.2.3 version up if needed.

Thanks for your responses!

[razorknight]

I got some help to figure out that the print commands needed the brackets because I'm a huge derp.

and I changed raw_input to input and it works, now.

I have no idea how to use it, but at least it doesn't give any errors...

[humbleElitist]

Ok, great!

The wiki on the github attempts to explain it.
I have also created a tumblr for the purpose of teaching the syntax of it, and then afterwards, strategies for writing things in it.

aaaaand I just noticed a bug...

ok, I fixed the bug with print, but there's still a bug that I need to fix.

theres a bug with the curly bracket matching...

I'm working on it.

I did not notice it until after I put it up.

The fix for the print command bug in on the file on github now, but the loops are still partially broken.

I'm glad you got it running!

EDIT:
most recent github version as of 14/9/12 (d/m/y) has fixed said bug.

[Miff]

I have no idea what I'm supposed to do with it so far... excellent adaption of the comic's version of ~ATH. ;p

You wouldn't mind throwing up a link to the tumblr here though?

[humbleElitist]

Sorry.
Sure.
It's not very far though.
http://learn-tilde-ath.tumblr.com/

I would also suggest the page
https://github.com/drocta/TILDE-ATH/wiki

As it explains the syntax to some degree.

I intend to improve the explanations.

Which would you consider a higher priority:
Fixing the loop part
Or
Improving documentation
?

Also, I can give a breuf explanation here:
Variables store objects.
Objects can be alive or dead.
~ATH(VARNAME){
Stuff
}
First, it Will check if the object in VARNAME is alive.
If not, it will jump to after the matching }
If it is alive, it will remember the starting position, and continue forwards.
It will then do whatever is in the place of stuff.
When it reaches the }, it will remember the last time a loop was started, and jump to there.

If you want to make the object stored in VARNAME dead, use VARNAME.DIE();
Note that this makes the object stored in VARNAME dead, not VARNAME itself.
Variables cannot be alive or dead.
They store objects that can be alive or dead.
What object a variable stores can change.

Variables are initialized in one of two ways:
The import statements. And the bifurcate statements.
The import statement syntax is as follows:
Import Jaffna idbejdi chendifu hcindubhdi etc VARNAME;
There can currently be any number of "words" before the variable name.
Please make sure to include the semicolon.

The second, bifurcation, is not just for initialization.
Bifurcate works as follows:
Bifurcate commands can take one of two forms:
BIFURCATE A[B,C];
And
BIFURCATE [B,C]A;

Again, semicolons are important!

For the first one,
BIFURCATE A[B,C];
Two objects are determined from the object stored in A, and the two objects are then stored in B and C.
Please note that the same objects will always result from this.
If you kill one of them, and then do the same operation but putting it in a different pair of variables, the same one will be dead.

The second is the inverse operation of the first and visa versa.
DESCRIPTION IN PROGRESS!

But still, this is really cool. Will it have something like an EXECUTE() command?

haha.
yeah, I wrote an interpreted language in an interpreted language.

That is something I tend to do.

____________________

Execute pretty much works, in that if you put execute and put the command inside the parens of the execute, it will run the code.
It doesn't know what to do with EXECUTE so it just ignores it.
and then executes the thing inside.

Yes, this is a terribly lazy and horrible way of doing things.
sorry about that.
I will probably improve that part later.

oh, were you thinking for running external scripts, like in unhackable.~ATH?

no, it does not have that feature currently.

thanks for expressing an interest!

[humbleElitist]

Ok, so the syntax is written up on the blog now.
I would appreciate it if you could tell me if any part of it is unclear, and if any part is unclear, what parts are unclear.

Also, theres two features that I am not sure which I should work on next, and would like input on.
The two features are user input,
and functions.

Both of which will be implemented eventually, but I don't know which one to create first.

If you are having trouble running it:
It needs to be run in python 2.7 (but if you are somewhat experienced in python you should be able to make a small change to make it work in 3.x)
Run the interp_2.py file, and then type in the file name.


Again, if anything is confusing, please tell me. I want to make it accessible as possible without damaging the language itself.

[Arsenicum]

Alright, I finally got Python to work on my shitty computer. When I get back from work I'll start writin' up some stuff and see what I can figure out.

[Fang]

This is awesome, man! Great work!

I've never written an interpreter myself, so I don't know how feasible this is, but you should make it so that we can escape special characters (like semicolons) to print them, for example.
If I want to print "Let me ; show you my semi;colons"
I'd say "print Let me \; show you my semi\;colons;"
And that'd escape the semicolons so they're put there without any effect.

Other than that, I suggest implementing user-input first instead of functions. Why? Personal preference.

Yes,
That can most definitely be done.
Not the most interesting thing to implement, but it can and shall be done.

One reason I was considering doing functions first was the way I was considering doing input.
I was thinking there could be a STDIN value, and the STDIN value could be bifurcated, and the left half would be an object associated with the variable name, and the right half would be the new STDIN.

OR

I could just make INPUT a function that creates an object and stores it in a value.
I am not sure what syntax I should use for that though.

I could use:

INPUT VARNAME;

or

INPUT(VARNAME);

Or I could just make STDIN change by itself.

Not entirely sure which of these I should use.

any suggestions about that?

[Arsenicum]

I can't seem to get it working, even with the correct version of Python.
Any time I enter anything, it just prints things (too fast to see) and closes.

EDIT: Under further review, it DOES work, but it still opens it too fast to see and closes.

Try running it from the command line or IDLE.

I guess I should add a pause after the program ends to see the output.

Adding
raw_input()
At the end of the python program should make it pause before it exits.

I suppose I could put that change up. Do you think I should?

Go for it.

It works fine from IDLE.

ok, made that change (it was just adding one line at the end)

I am working on user input now...

I still would like suggestions for the syntax of getting user text input though.

[Arsenicum]

How about something like...

import klondikeBar A;

~ATH(<input: text> A)
{
print A
}

"<input: text>" is basically just a way of saying "convert the user input into a string", then setting the variable "A" to that string, and then printing it. I think this would work well because you could also write "<input: int>" and it would convert the input into an integer.

I think that would work pretty well. It's sure as hell not as complicated as Java and their god-forsaken user input.

But then how do you time when it inputs?

Aside from the usual shenanigans.

[Arsenicum]

Maybe throw up a command like "prompt()"?

Maybe have it all in a command like..

A.prompt(input : text);

[humbleElitist]

What do you feel about
A.PROMPT();
?
To set A to an object related to the string?

The first thing you suggested, I was uncertain what you meant.
Why was it inside the parenthesese for the ~ATH loop?

Note:
You speak of having it convert to either a string or an int.
There is no primitive int type, one uses bifurcate to construct a value, which can be used as a number.

So I was thinking all input would be text.

So converting to text doesn't make much sense.


I was also considering just
INPUT A;
.

Was any of this unclear?
I should be asleep right now, so I might have mis. "spoken" .

[dotHacker]

How do you install this into python? (Total programming noob here. Sorry!)

A.PROMPT(); is cool.
INPUT A; is also cool. It reminds me of assembly code.

The reason things were really strange is because I didn't really follow a specific syntax when suggesting it. I was just writing it how I would think it would be written (in which case, it'd be Arsenicum~ATH instead of Drocta~ATH, ahahaha).

I totally forgot about bifurcating, though. So yeah, it works pretty well without an input type.

[Miff]

I like A.PROMPT(); because it seems to fit in more with "canonical" ~ATH. Maybe with a different name then Prompt though to fit in with the "life and death" theme, although I don't know what would be fitting.
