I Couldn't Help But Notice That Out Of Some Of The Best Things You Could Do, No Link To The Download

Bug

Ok, if you tried running a script with the interpreter, it might not have run properly. The part of the code that handles what part of the code is executed next is buggy. It is in the process of being fixed. Also, if python gives you a syntax error, it is probably because you are using a different version of python. Change raw_input to input And change print stuff to print(stuff) I will post an introduction to the syntax soon.

My ~ATH keeps crashing whenever I run a non-computer exploding code, or if I press enter. Why is this?

Based on the username which recently followed this blog at the same time as I received this ask (which I won't say what it was because you asked this on anon, and haven't received permission), I'd guess that you may be running a different version of ~ATH than the one I document here :P

Unfortunately, I don't have a specification for the version you have.

If you have such a specification, or the executable for it, I'd be happy to take a look if you could send it to me, haha.

If on the off chance you are using the version I document here, then presumably you have a syntax error or something in your code?

How do you use this?

Just to be super clear, though you probably understand this, “drocta ~ath” is not for practical purpose. It is purely an amusement.

That being said, to run this, you need to have python 2 installed. (Yes, currently most new python projects are in python 3. Unfortunately I haven’t gotten around to making any of the updates I’ve wanted to on this project, and it has been years since I’ve worked on it.)

To run it: download the github repository from https://github.com/drocta/TILDE-ATH

then, (probably from the command line, though running it in other ways may also work) navigate into the folder where you put all those files, use python 2 in order to run interp_2.py  . [1] Then, it will allow you to type something in. It would be good if it gave some sort of prompt saying that it is accepting input, but it currently does not. What you have to type in is the file name of the drocta ~ath program that you want to run.

for example, you might type:

python interp_2.py looptest.~ATH

in order to run the program looptest.~ATH , and then you would see the output:that alternates between “APPLE” and “ORANGE” a number of times (like, 5 times I think).

If it isn’t working for you, let me know and I can try and help you troubleshoot what’s going on.

If you are asking, not “how do I run the programs in this language” but “how do I write programs in this language”, uh, read through the rest of this blog I guess. It isn’t complete, but the point of this blog was meant to be a tutorial for how the language works. If you have any particular questions about how to do a particular thing in the language, then ask that. But I don’t currently have time to re-do the whole project of this blog and put a tutorial for the language as a whole in one response to an ask.

P.S. I am currently in grad school for math (I made this language while in high school). I haven’t been doing all that much programming lately unfortunately.

([1] What’s that? “interp_2.py” is a weird name for the main file? Indeed it is. Originally I had “interp.py” and then before I started using git I made a new version which I called interp_2.py, and then, for basically no good reason, I kept that name for the file. If I go back to this at all, I suspect that I will change that to just “interp.py” or maybe “main.py” or something. idk.)

Merry Christmas!

Ok, apparently I hadn't pushed the code that allows user input to github.

I had written the code for user input a while ago, but apparently it didn't get put on github. And then my local copy got deleted. But I rewrote it today, and I fixed a bug with reverse bifurcation. So it should work now. And I have confirmed that it did indeed get put on github, so I don't need to worry about this happening again.

reading binary numbers from the user, continued.

when we left off, we had code to interpret one binary number from user input, and output it as a unary number. In this post we will add the second user input, and maybe make a thing that converts from unary to binary, and then outputs it.

The code for that was the following:

import blah BLAH; print please enter whatever character you will be using for binary zero.; INPUT ZEROCHAR; BIFURCATE ZEROCHAR[ZEROCHAR,JUNK]; import chrcmp CMP0; BIFURCATE [CMP0,ZEROCHAR]D; D.DIE(); print please enter whatever character you will be using for binary one.; INPUT ONECHAR; BIFURCATE ONECHAR[ONECHAR,JUNK]; import chrcmp CMP1; BIFURCATE [CMP1,ONECHAR]D; D.DIE(); BIFURCATE [NULL,NULL]2NULL; BIFURCATE 2NULL[OUTNUM,JUNK]; print please input the binary number you want.(it will be converted to unary); INPUT BINNUM; ~ATH(BINNUM){ BIFURCATE [OUTNUM,OUTNUM]G; BIFURCATE G[NCOPY,OUTNUM]; ~ATH(NCOPY){ BIFURCATE NCOPY[JUNK,NCOPY]; BIFURCATE [BLAH,OUTNUM]OUTNUM; }  BIFURCATE BINNUM[CHAR,BINNUM]; BIFURCATE [CMP0,CHAR]NEQ0; ~ATH(NEQ0){ BIFURCATE [BLAH,OUTNUM]OUTNUM; BIFURCATE 2NULL[NEQ0,JUNK]; } } print ok, going to print it out in unary, with each digit on one line. If the number you entered was large you might want to close the program instead of hitting enter.; INPUT JUNK; BIFURCATE [OUTNUM,OUTNUM]GOUTNUM; BIFURCATE GOUTNUM[OUTNUMCOPY,JUNK]; ~ATH(OUTNUMCOPY){ BIFURCATE OUTNUMCOPY[JUNK,OUTNUMCOPY]; print 1; }

ok, so what do we need to do after that?

Well we need to make it get two numbers, right?

Yes. Yes we do.

But getting one number was kind of long, wasn't it.

Luckily we don't have to have the entire thing there twice, much of it we can jusst have it in there once.

we COULD define a function, but I haven't added that to the interpreter yet, so yeah...

so a significant portion of that was initialization stuff that doesn't need to be duplicated. the first 14 lines in fact!

so pretty much we just duplicate everything but the first 14 lines.

gee, now I sound lazy for not writing this part earlier.

anyway, here goes:

import blah BLAH;

print please enter whatever character you will be using for binary zero.;

INPUT ZEROCHAR;

BIFURCATE ZEROCHAR[ZEROCHAR,JUNK];

import chrcmp CMP0;

BIFURCATE [CMP0,ZEROCHAR]D;

D.DIE();

print please enter whatever character you will be using for binary one.;

INPUT ONECHAR;

BIFURCATE ONECHAR[ONECHAR,JUNK];

import chrcmp CMP1;

BIFURCATE [CMP1,ONECHAR]D;

D.DIE();

BIFURCATE [NULL,NULL]2NULL;

BIFURCATE 2NULL[OUTNUM,JUNK];

print please input the first binary number you want.(it will be converted to unary);

INPUT BINNUM;

~ATH(BINNUM){

BIFURCATE [OUTNUM,OUTNUM]G;

BIFURCATE G[NCOPY,OUTNUM];

~ATH(NCOPY){

BIFURCATE NCOPY[JUNK,NCOPY];

BIFURCATE [BLAH,OUTNUM]OUTNUM;

} 

BIFURCATE BINNUM[CHAR,BINNUM];

BIFURCATE [CMP0,CHAR]NEQ0;

~ATH(NEQ0){

BIFURCATE [BLAH,OUTNUM]OUTNUM;

BIFURCATE 2NULL[NEQ0,JUNK];

}

}

BIFURCATE [BLAH,OUTNUM]UINNUM1;

BIFURCATE UINNUM1[JUNK,UINNUM1];

BIFURCATE 2NULL[OUTNUM,JUNK];

print input the second binary number:;

INPUT BINNUM;

~ATH(BINNUM){

BIFURCATE [OUTNUM,OUTNUM]G;

BIFURCATE G[NCOPY,OUTNUM];

~ATH(NCOPY){

BIFURCATE NCOPY[JUNK,NCOPY];

BIFURCATE [BLAH,OUTNUM]OUTNUM;

} 

BIFURCATE BINNUM[CHAR,BINNUM];

BIFURCATE [CMP0,CHAR]NEQ0;

~ATH(NEQ0){

BIFURCATE [BLAH,OUTNUM]OUTNUM;

BIFURCATE 2NULL[NEQ0,JUNK];

}

}

BIFURCATE [BLAH,OUTNUM]UINNUM2;

BIFURCATE UINNUM2[JUNK,UINNUM2];

BIFURCATE [UINNUM1,UINNUM1]CUINNUM1;

BIFURCATE CUINNUM1[SUM,JUNK];//haha, some junk

BIFURCATE [UINNUM2,UINNUM2]CUINNUM2;

BIFURCATE CUINNUM2[UINNUM2CPY,JUNK];

~ATH(UINNUM2CPY){

BIFURCATE UINNUM2CPY[JUNK,UINNUM2CPY];

BIFURCATE [BLAH,SUM]SUM;

}

print ok, going to print the sum out in unary, with each digit on one line. If the numbers you entered were large you might want to close the program instead of hitting enter.;

INPUT JUNK;

BIFURCATE [SUM,SUM]GSUM;

BIFURCATE GSUM[SUMCOPY,JUNK];

~ATH(SUMCOPY){

BIFURCATE SUMCOPY[JUNK,SUMCOPY];

print 1;

}

ok. That worked. I haven't made it convert the output to binary yet. I started this the day of the other post, but there was a bug I didnt get around to fixing in it that I didn't find the fix for until today.

that bug was that in the part where it changes the binary number to a unary number, the first time around, the unary number starts at zero and increases to what it should be...

...but I forgot to include the line to reset it back to zero for the second number.

but in works now.

I might make the part where it converts from unary to binary now instead of later, but I have to do stuff.

Sorry for having such a slow post rate, it is partly because I am busy and partly because I am lazy. mostly the [FORMER,LATTER].

hey, it adds the numbers that were entered in binary...

So a future improvement is to make it so it outputs it in binary as well.

Another possible future post is something that shouldn't work but the interpreter has a certain bug that might be amusing, and will not negatively affect many things.

specifically, if you have a "}" inside of a print statement, and you are jumping to the end of a loop, it will jump to the inside of the print statement, and execute the text as code. This is a bug, not a feature, so you should not rely on it when writing stuff. It might be fun to mess with though.

I might add user defined functions to the interpreter soon...

I don't feel that this post really explained much of anything, but I have to do stuff now, so I am going to post this, and possibly modify it later with clarifications.

Feel free to send me messages asking about how some part works.

yeah, can i make ~ATH continue to generate variables? like if one part of the program dies it generates another variable? because i've been trying to do that lmfao

Hi. Not sure what you mean by continue to generate variables. If you mean like how in lisp you can like, automatically generate a new variable name and then use that variable name, then no, drocta ~ATH doesn't have a feature like that, but I'm guessing that's not what you mean.

Variables are just like, names in your program. If you want more objects, you can just continue bifurcating objects to get more objects.

drocta ~ATH does not support parallelism or concurrency or whatever (though presumably canonical ~ATH would, in some sense. At least, it appears to handle circumstantial simultaneity.), So, if you are referring to drocta ~ATH, then I'm not sure what you mean when you refer to part of the program dying. Though, given that in canonical ~ATH, there is the expression

[THIS,THIS].DIE();

then it seems like, presumably, it should be possible to have something like

THIS.DIE();

in order to describe part of the program dying (ending), without another part doing so.

But, again, drocta ~ATH does not support anything like that. Feel free to make a fork of it which does though. Please let me know if you do!

Hello again all!

So recently I started kind of working on this again for a bit. I have fixed some bugs with the parser that I haven't pushed yet. I am also writing an improved interpreter that will use the parser instead of the hacky thing that just goes through strings.

However, for the time being, even after I release this version, I would recommend maybe using the older version for a while if anyone is using it, because this version is probably even more buggy.

However, you know how a few posts ago (but more than a year ago (wow) ) I posted that post where I said that I didn't think bifurcate can be used to split values into more than 2 values?

Well I still kind of think that, but on the map page for homestuck on act 6, it says split Act_6[Act_1,Act_2,Act_3,<etc>];

So this is something I intend to implement, and something I am implementing.

And like I said before I would like it to be done with repeated bifurcation, as a sort of syntactic sugar.

And I am thinking I want it to be like

[a,b,c] means the same thing as [a,[b,c]]

so split Z[A,B,C];

would be the same as

BIFURCATE Z[A,BCTEMP]; BIFURCATE BCTEMP[B,C];

and that split [A,B,C]Z;

would be the same as

BIFURCATE [B,C]BCTEMP; BIFURCATE [A,BCTEMP]Z;

But the way the splits would be done could also be backwards

so [a,b,c] could be the same as [[a,b],c]

I'm pretty sure I prefer the first way, but the second way is actually easier to implement.

or at least cleaner looking to implement.

Why doesn't my code look clean ever?

Anyway, my reason for this post is this:

Does anyone have any opinions about how split is implemented?

User input, and a basic calculator.

Most programs people use have some form of user input. A calculator isn't much use if it always uses the same numbers after all!

~ATH of course accepts user input and output as shown in the file Roxy sent Jane.

Also I just found out you can put more than one read more line in one post.

The input command has the syntax:

INPUT VARNAME;

What this does is when program execution meets this line, the program pauses execution, allowing the user to input text. When the user hits enter, program execution will continue and the variable VARNAME will be made to point to an object corresponding to the text the user entered.

This object is such that the left half is the object that corresponds to the first character. If there is no character after that, the right half will be the NULL object. Otherwise the right half will be the object corresponding to the input without the first character. If they hit enter without inputting any characters the object will just be the NULL object.

Now that we have that all explained, we can start to make programs that actually take user input!

As you might have guessed from the title, the thing we will be making is a very basic calculator. All it does is add two numbers, like in the last example.

But in this, it will get the numbers from the user!

One simple way to do this is to use the length of the input text as the number: The way we define what we call numbers just so happens (heh) to be such that if we interpret the object for the input string as a number, the number will be the same as the length of the input!

This isn't the greatest solution, but it is easier than other methods. We will use this method first and then move on to other methods that are harder to write, but will be nicer when using the end program.

HERE WE GO:

ok, so like I said, much of it is pretty much the same as that previous program, so we might as well just include said here:

SOME CODE TO GET A AND B HERE import bluh BLAH; BIFURCATE [BLAH,A]ATEMP; BIFURCATE [BLAH,B]BTEMP; BIFURCATE ATEMP[JUNK,ATEMP]; BIFURCATE BTEMP[JUNK,BTEMP]; BIFURCATE [BLAH,NULL]C; BIFURCATE C[JUNK,C]; ~ATH(ATEMP){ BIFURCATE ATEMP[JUNK,ATEMP]; BIFURCATE [BLAH,C]C; } ~ATH(BTEMP){ BIFURCATE BTEMP[JUNK,BTEMP]; BIFURCATE [BLAH,C]C; } BIFURCATE [BLAH,C]CTEMP; BIFURCATE CTEMP[JUNK,CTEMP]; ~ATH(CTEMP){ BIFURCATE CTEMP[JUNK,CTEMP]; print some text; } print DONE!; 

so pretty much what we need to do it put the code to get A and B where that goes(at the beginning), as well as stuff to tell the user how to print stuff.

Like I said, the objects from the input commands can be interpreted as numbers.

so this becomes:

print INPUT SOMETHING WITH THE NUMBER OF CHARACTERS AS THE FIRST NUMBER YOU WANT TO ADD; INPUT A; print INPUT SOMETHING WITH THE NUMBER OF CHARACTERS AS THE SECOND NUMBER YOU WANT TO ADD; IMPORT B; import bluh BLAH; BIFURCATE [BLAH,A]ATEMP; BIFURCATE [BLAH,B]BTEMP; BIFURCATE ATEMP[JUNK,ATEMP]; BIFURCATE BTEMP[JUNK,BTEMP]; BIFURCATE [BLAH,NULL]C; BIFURCATE C[JUNK,C]; ~ATH(ATEMP){ BIFURCATE ATEMP[JUNK,ATEMP]; BIFURCATE [BLAH,C]C; } ~ATH(BTEMP){ BIFURCATE BTEMP[JUNK,BTEMP]; BIFURCATE [BLAH,C]C; } BIFURCATE [BLAH,C]CTEMP; BIFURCATE CTEMP[JUNK,CTEMP]; ~ATH(CTEMP){ BIFURCATE CTEMP[JUNK,CTEMP]; print some text; } print DONE!; 

So yeah. That should work. I still need to test this, but I am pretty dang sure that this works.(have to go do homework now) In the next post I will explain how to make it so that the user can type in the number as an actual number!

I've realized that my tutorials haven't been tutorial-y enough

I've realized that recently, my tutorial posts have been too much code and not enough explanation. That was a mistake on my part, so I am going to go back now and give better explanations.

Also, I have started to make a table of contents page.

I figured that if someone wanted to read the tutorial after a significant part of it were finished, that they might have trouble, because it would kind of be in reverse order.

So TABLE OF CONTENTS AHOY!

Yeah.

So uh, any suggested changes to the format of the TOC page?

Why cant I mark this as a post that can be answered? I can let people photo reply, but once it goes in drafts I can't let people answer this question? Or is it too long?

What is with this interface?
