alpha

a stack based programming language

why make this?

i was watching a youtube video (i forgot the name sorry :(..), i got inspired by it to create this. additionally, since i had a school project coming up where i had to create a programming language, i thought itd be a great idea to get the feels of it by starting with this simpler project.

roadmap

quit command
input command
macros
multiple stack support
variable support

building

run build.sh (*nix only)

syntax

push

PUSH <val>

pushes to the stack

math

ADD
SUB
MUL
DIV

does an operation on the top two elements of the stack

print

PRINT

prints the top element of the stack

pop

POP

removes the top element of the list

dump

DUMP

clears the stack and prints everything

duplicate

DUP

duplicates the top element and adds it to the stack

swap

SWAP

swaps the top two elements of the stack

depth

DEPTH

returns the depth of the stack

stack

STACK

returns the entire stack, like DUMP but it doesnt purge the stack

drop

DROP

purges the stack, like DUMP but it doesnt return the stack

rot

ROT

rotates the top three elements of the stack: [1, 2, 3] ROT => [2, 3, 1]

jump, label

LABEL labelname
JUMP labelname

JUMP makes the code skip everything between it and LABEL can be used to make infinite loops

if else

IF
PUSH true
ELSE
PUSH false
ENDIF

if statement executes the code between it and else if the top element in the stack is true if statements need an endif

greater than, less than, equals to

GT
LT
EQ

these operators pop the top two elemnts and add the result to the stack
