PEWWWWW
Note: This is a work in progress. Some things may not be fully finished. You can find the original spec here.
PEWWWWW is an esolang created by User:Emerald. This specification was written by User:Monochromeninja. The language uses a single stack that only contains integers.
Instructions
An instruction of PEWWWWW is written like so:
/== (statement> |condition
Statements
Statements can be one of the following:
load n
Pushes n to the stack.
shoot
Prints the top of stack.
search n
Moves the n'th item from the top of the stack to the top. (1-based)
reload n
Jump to the n'th instruction from the top of the program. (1-based)
add
Pops a then b, then pushes a+b.
sub
Pops a then b, then pushes a-b.
mul
Pops a then b, then pushes a*b.
div
Pops a then b, then pushes a//b. (Floor division -- divide and round down)
mod
Pops a then b, then pushes a%b.
Statements can be separated using )s.
Conditions
Conditions can use the following operators:
== (equal to) >> (greater than) << (less than) >= (greater or equal to) <= (less or equal to) ! (logical NOT)
Literals
Valid literals are:
- Integers (themselves)
tru(Boolean TRUE)fal(Boolean FALSE)- Strings (use double-quotes)
- Escape character: \
- Newline: \p
top(Top of stack)get(Returns a single ASCII code from STDIN)toint s(Returns s converted to an integer)tostr i(Returns i converted to a string)
Compressed mode
This allows you to write smaller (albeit less readable) programs. Simply separate your statements with ;s and use this instead of the standard ASCII art gun:
condition/==statement
These can be interspersed with noncompressed statements as well.
"Extras"
These are extra stacks that can be used as variables. Declare them using the following syntax:
extra var |value| |value| <etc.>
To evaluate a statement inside a stack value, simply surround it with angle brackets like so: |<get>|.
