~-~! (No Comment) [Esoteric Programming Language]

technoboy10

joefarebrother and I invented an esoteric programming language! You can find more about it here: http://esolangs.org/wiki/No_Comment

Is there a way to program in it?

Not yet. It was invented on Saturday. We are planning on making an interpreter for it sometime soon though.

Still, pretty cool. How do you plan on making the interpreter? (C++?)

I assume some version of C (for speed, at least), but I really don't know. jfb and I will discuss it.

Ok, thanks (I really don't know that much about language compilers and interpreters right now)

Nor do I, TBH. :p

Almost ANYTHING can be assigned - even ~ = ~~ is legal - from that point on, all tildes will have the effect that two tildes would have had before. Unless some variable had an odd value, you have no way to get back odd numbers.

What about ~~ = ~?

Challenge: Write a self-interpreter.

Gravitation

And how would one add 2 variables together?

EDIT: ‘+’'. I'm so stupid xD

EDIT AGAIN: I used this in a golf for Hello World obfuscation, you were only allowed to break one of these rules:

Does not contain the characters: “h”, “l”, “w” and “d” in any case
Does not contain the characters: “e”, “o”, “r”, “0”, and “1” in any case
Does not contain the characters: “2” or “7”

The code I entered:

'=~~~:''=~~~~:'''=~~~~~:@~~,'',',':@''',''',''+~:@'',',',':@'',',',':@''',''',''+<''',~~+~>:@'','',~~:@'',~~,<''',~~>+'+'':@''',''',''+<''',~~+~>:@''',''',''+<<'+''>,~~>:@'',',',':@''',''',''

I should have written a recursive function, but I was lazy. xD

The winning code is in GolfScript:

'·š““ß¨“›'{~}%

written by Chris Jester-Young. But, ~-~! is pretty good for character constraint challenges.

@Gravitation that's awesome!

By the way, just because I'm bored, I'm writing an interpreter for this in Python (as stupid as it is). I'm calling it 0# (zerohash/zeroHash alphanumerically) (the equivalent of `~-~!` in Python).

Cool, please post a link to it here (or on Esolang) when you're done.

No problem. I'm up to 100 lines and it's only been 4 hours! xD

Sorry for double post, but could you elaborate more on exporting symbols in libraries, and can I get a list of operators sorted by precedence?

EDIT: Um, your Esolang page says that the pipes ( | | ) return the unicode byte string of a string as an integer. But, Unicode uses 4 bytes to represent 1 character: for instance, “h” is 00000000000000000000000001101000 and “i” is 00000000000000000000000001101001, so wouldn't “hi” be 0000000000000000000000000110100000000000000000000000000001101001, which is 446676598889, not 26729…?

EDIT: 26729 is 0110100001101001, which is 01101000 (ascii h) and 01101001 (ascii i). So, you might want to swap out “unicode” for “ascii” or change the 26729 to 446676598889.

EDIT: So far tokenization works quite well. All I have to do now is write a function to create an expression's hierarchy according to the order of operations. Then, I just have to evaluate it (easy). Right now I'm working on representing an operator in a variable with a specific class instance but I'm a bit stuck on backtrace (e.g., the evaluator looking at the code and knowing which variables are operators and which ones aren't), but I can figure something out.

Tokenizer in action:

>>> '=|*==%[%]~~+'&*-~|
["'", '=', "|*==%[%]~~+'&*-~|"]
>>> *==%[%]~~+'&*-~
['*', '==', '%', '[', '%', ']', '~~', '+', "'", '&', '*', '-', '~']
>>> '=~~~:''=~~~~:'''=~~~~~:@~~,'',',':@''',''',''+~:@'',',',':@'',',',':@''',''',''+<''',~~+~>:@'','',~~:@'',~~,<''',~~>+'+'':@''',''',''+<''',~~+~>:@''',''',''+<<'+''>,~~>:@'',',',':@''',''',''
["'", '=', '~~~', ':', "''", '=', '~~~~', ':', "'''", '=', '~~~~~', ':', '@', '~~', ',', "''", ',', "'", ',', "'", ':', '@', "'''", ',', "'''", ',', "''", '+','~', ':', '@', "''", ',', "'", ',', "'", ',', "'", ':', '@', "''", ',', "'", ',', "'", ',', "'", ':', '@', "'''", ',', "'''", ',', "''", '+', '<', "'''", ',', '~~', '+', '~', '>', ':', '@', "''", ',', "''", ',', '~~', ':', '@', "''", ',', '~~', ',', '<', "'''", ',', '~~', '>', '+', "'", '+', "''", ':', '@', "'''", ',', "'''", ',', "''", '+', '<', "'''", ',', '~~', '+', '~', '>', ':', '@', "'''", ',', "'''", ',', "''", '+', '<', '<', "'", '+', "''", '>', ',', '~~', '>', ':', '@', "''", ',', "'", ',', "'", ',', "'", ':', '@', "'''", ',', "'''", ',', "''"]

It should be UTF-8 is what I meant. It's variable-width so the bottom 128 ASCII values can be represented in 1 byte yet if the high-bit of this byte is 1 then you can have more bytes.
Awesome tokeniser BTW!
Also, be warned that I plan on adding a special form involving the # character so the tokeniser should signal an error

I'm a bit scared of utf-8. xD How do you decode the bitstring, if it's variable length?

print ('%x' % int(binarydata, 2)).decode('hex').decode('utf-8')

Thank you, Igonato from StackOverflow. xD
