baa
baa is a register-based esolang created by User:Joaozin003 where each command has the form "b*insert two or more a's*"
Syntax
The syntax is very easy to understand.
Also, commands can only appear once per line.
Numbers
It's the only form of objects and can be passed as arguments to some commands (more on that later!) and is held by the registers (more on that later!).
Numbers are represented by any amount of consecutive letters (not at the start of the line, otherwise it's a command) and the amount of letters is the number.
Examples: 10 = tenletters, 11 = elevenchars
Registers
Registers can hold numbers and are the "replacements" of variables.
There are 3 registers in baa and we call them a, b and r.
Registers a and b serve as inputs for mathematical operations and r is the result of them.
Constants
The only constant is zero (represented by 0) (it's a constant because it can't be achieved without mathematical operations) and can be put in registers a and b just like if it was a normal number.
Commands
| Command | Description |
|---|---|
| baa | Start program |
| baaa | End program |
| baaaa | Print specified number as Unicode |
| baaaaa | Print the r register as Unicode |
| baaaaaa | Set the a register to the specified number |
| baaaaaaa | Set the a register to the r register |
| baaaaaaaa | Set the b register to the specified number |
| baaaaaaaaa | Set the b register to the r register |
| baaaaaaaaaa | Set the r register to the sum of a and b |
| baaaaaaaaaaa | Set the r register to the difference of a and b |
| baaaaaaaaaaaa | Set the r register to the product of a and b |
| baaaaaaaaaaaaa | Set the r register to the quotient of a and b |
| baaaaaaaaaaaaaa | Set the r register to a modulo b |
| baaaaaaaaaaaaaaa | Set the r register to a squared |
| baaaaaaaaaaaaaaaa | Put a label here with a id of the line number |
| baaaaaaaaaaaaaaaaa | Goto the label with a id of the specified number if a > 0 |
| baaaaaaaaaaaaaaaaaa | Goto the label with a id of the specified number if b > 0 |
| baaaaaaaaaaaaaaaaaaa | Goto the label with a id of the specified number if r > 0 |
Example programs
Print every Unicode character
baa baaaaaa 0 baaaaaaaa a baaaaaaaaaaaaaaaa baaaaa baaaaaaaaaa baaaaaaa baaaaaaaaaaaaaaaaa four baaa
This program loops and prints all unicode characters (starting with NUL) until unicode ends and the interpreter likely throws an exception.
