EXSES

WARNING: THIS PROGRAMMING LANGUAGE IS UNFINISHED! EVERYTHING MAY CHANGE IN THE FUTURE!

EXSES - smol stack-oriented concatenative programming language. Development have just started: do not expect something revolutionary new.

Language Reference

Example

Hello, World!

[Hello,\sWorld!] !

Basic

20 10 + ! # Will output the '30'
# Raise 5 to the power of 2
5 & # `&` will duplicate top value e.g '5'
* # Multiply
! # Output

Control flow

500 80 > ( # if 500 is less than 80 do following code block
    99 !
) # close the block

More advanced

Bindings

# bind 500 to '1100'. NOTE: You can use strings as names
1100 500 <-
# bind 80 to '1101'
1101 80 <-

# load value of '1100' (e.g 500)
1100 ^
# load value of '1101' (e.g 80)
1101 ^
- # subtract
! # print (420)

Procedures

1100 ' # int  # create a procedure named "1100". NOTE: You can use strings as names
    80 - ! # body of the procedure. subtract 80 from the value that was on top of the stack when procedure was invoked and print the result
" # close the procedure

500 1100 : # `:` call a procedure
