UwuScript
World's first uwu-oriented language.
Saw a tweet from Uwy and thought it'd be a tasty little meme morsel to actually build with a tokenizer I have lying around. It's basically Brainfuck but with a special token for single-line comments. If you're looking for the plain old Brainfuck interpreter I wrote in C#, it's called ByteRibbon.
Here's a hello world program in UwuScript:
uwu uwu uwu uwu uwu uwu uwu uwu uwu uwu ow< >w> uwu uwu uwu uwu uwu uwu uwu >w> *w* Comment!
uwu uwu uwu uwu uwu uwu uwu uwu uwu uwu >w> uwu uwu uwu >w> uwu <w< <w< <w< <w<
nwn >wo >w> uwu uwu owo >w> uwu owo uwu uwu uwu uwu uwu uwu uwu owo owo uwu uwu
uwu owo >w> uwu uwu owo <w< <w< uwu uwu uwu uwu uwu uwu uwu uwu uwu uwu uwu uwu
uwu uwu uwu owo >w> owo uwu uwu uwu owo nwn nwn nwn nwn nwn nwn owo nwn nwn nwn
nwn nwn nwn nwn nwn owo >w> uwu owo >w> owo *w* Hello world!
The following table is straight from Wikipedia's table of Brainfuck commands, but modified to show each command's UwuScript equivalent:
| UwuScript | Brainfuck | Meaning |
|---|---|---|
>w> |
> |
Increment the data pointer (to point to the next cell to the right). |
<w< |
< |
Decrement the data pointer (to point to the next cell to the left). |
uwu |
+ |
Increment (increase by one) the byte at the data pointer. |
nwn |
- |
Decrement (decrease by one) the byte at the data pointer. |
owo |
. |
Output the byte at the data pointer. |
-w- |
, |
Accept one byte of input, storing its value in the byte at the data pointer. |
ow< |
[ |
If the byte at the data pointer is zero, then instead of moving the instruction pointer forward to the next command, jump it forward to the command after the matching ] command. |
>wo |
] |
If the byte at the data pointer is nonzero, then instead of moving the instruction pointer forward to the next command, jump it back to the command after the matching [ command. |
*w* |
N/A |
Denotes a single-line comment. |
You're essentially manipulating a Turing machine to produce output. Anything written in Brainfuck is obviously trivial to port over.
Usage
Compile the project in Visual Studio, run it like this:
UwuScript.exe "examples/hello.uwu"
Limitations
Largely untested and very unoptimized, the Turing machine underlying the language is a very hasty port from the PHP version in my ancient Brainfony repository. It's gonna be buggy and slow.
Also, random inline text will break the tokenizer, that's why the single-line comment token was added. It's easy to change this so you can stick non-instructions wherever you like (like I believe Urban Muller's original Brainfuck implementation does) by changing the regular expressions that the tokenizer is initialized with.
