Violence 🤬

A functional 🤑 first programming language with limited types and basic features.

Install 😇

Building from source

Build

Requirements:

sudo apt install -y build-essential cmake

git clone https://github.com/0xleft/violence.git
cd violence
# if you are not on linux you can use wsl or docker
cat build.sh
chmod +x build.sh
./build.sh <platform> # currently supported: linux
# move the binary to /usr/local/bin or to your PATH
# Enjoy :)

Variables

In Violence variables are declared using a type before them.

Types are:

lemon for numbers
word for strings
mood for booleans

Note

In the future I plan to change lemon to char and have arrays as new type

lemon a : 5
word b : "Hello World"
mood c : "good"

You can easely change between types for example when you want to print a number as a string you can do:

lemon a : 5
word b : a
~ here b is now "5"

You can also change a string to a number:

word a : "5"
lemon b : a
~ here b is now 5

This works for all types.

Functions

Builtin functions

say

Print to stdout

( say -> "Hello World" )

ask

Read from stdin until newline

( ask -> "What is your name?" )

read

Read from a file

( read -> "file.txt" )

write

Write to a file

( write -> "file.txt" -> "Hello World" )

sheesh

Which stands for execute shell command

( sheesh -> "ls" )

exit

( exit )

Examples

Hello World

( say -> "Hello World" )

FizzBuzz

f-> mod -> number -> mod_number -> lemon
    lemon output : number % mod_number
<-f

f-> fizzbuzz -> count -> max_count -> void
    lemon count = count + 1
    word output = ""

    if ( mod -> count -> 3 ) == 0
    word output = output + "fizz"

    if ( mod -> count -> 5 ) == 0
    word output = output + "buzz"

    word temp : count
    if output == ""
    ( say -> temp )

    if output != ""
    ( say -> output )

    if count <= max_count
    ( fizzbuzz -> count -> max_count )
<-f

( fizzbuzz -> 0 -> 10 )

Importing a file

( get -> "example/simple.vio" )

( function_from_simple_vio )

You can find more examples in examples folder
