g4m3rscr1pt

This is an esolang that transpiles to JavaScript. The language has its name because no variables, functions or file names are allowed to use vowels, inspired from leetspeak. Everything else in the language has basically nothing to do with gaming and is instead just random things my friends and I thought of to be annoying to use.

The file extension for g4m3rscr1pt files is .p0g. Every g4m3rscr1pt program will loop forever with a 0.1 second delay between each repetition so to terminate a program you must throw an exception. The examples folder of this repo has some example g4m3rscr1pt programs.

Installation

You will need node and npm.

npm install -g g4m3rscr1pt

I also recommend getting the g4m3rscr1pt VSCode extension for syntax highlighting.

Usage

1. Create a file that ends with .p0g (make sure there's no vowels in the name).
2. Code in the file.
3. Transpile using les gooo f1le.p0g output.js.
   • If no output file is specified, the code will just be immediately executed instead.

Numbers

Numbers in g4m3rscr1pt are base 5 and are represented with the vowels (a is 0, e is 1, i is 2, o is 3, u is 4). For example, eo is 8 and uio is 113.
Note: when numbers are printed, they are displayed normally.

Strings

You use ] to open a string and [ to close it. For example ]this is a string[. Only single line strings exist.

Variables

Variables can be any combination of consonants and numbers. For example v, l3tt3r, mNb and 9 are all valid variables. To assign a value to a variable, you write the name, then a colon and then the value like this:

n4m3: ]Joe[
d0ll4rs: oi

Comments

Using an @ makes the rest of the line a comment. There are no multi-line comments.

@this is valid comment
tw0: i @ so is this
@ tw0: e
/R33333{tw0} @prints 2

Commands

Functions in g4m3rscr1pt are called commands.

Defining Commands

To define a command first write the name of the command, then moment. If it has any parameters, then write a pair of curly brackets and write the parameters within them, separated by a space. Don't include any curly brackets if there's no parameters. ??!?1! is then used to start the definition and !?!!?? to end it. Within those is where you write the code for the command. To return a value, write https://imgur.com/jWr67J8 followed by the value. Here's an example:

@ addition command
4dd moment {x y} ??!?1!
  n1: /M1n7S{a e} @ negative 1
  ny: /D1V1D3{y n1} @ negative y
  https://imgur.com/jWr67J8 /M1n7S{x ny}
!?!!??

Executing Commands

To execute a command, type a / and then the name of the command. If there's any arguments, add a pair of curly brackets and separate each argument within them with a space. Example:

@ use the add command defined above
/R33333{/4dd{i o}} @ prints 5
/BR4P @ throws an error

Super Commands

Using multiple / is called a super command. The value returned by the command is put back in as the first argument as many times as there are /. 99_b0ttl3s_2.p0g in the examples folder utilises this.

x: /////M1n7S{ia e}
/R33333{x} @ prints 5

Default Commands

These commands are predefined in every g4m3rscr1pt program. Any commands that use maths will throw an error if rounding the result is not a safe integer (according to JavaScript). Also note that since g4m3rscr1pt transpiles to JavaScript, it has type coercion. For example:

/M1n7S{ea u}  @ 1
/M1n7S{]5[ u} @ 1

R33333 {output}

Prints output to the console. Returns what is printed.

cl1ck1tyCl1ck {prompt}

Prints prompt to the console and returns the user's input.

M1n7S {x y}

Returns x minus y.

D1V1D3 {x y}

Returns x divided by y.

R00t {x y}

Returns x to the yth root.

chr1s {seconds}

Pauses everything for seconds.

f1r3tr7ck {text}

Returns text but red.

d1n0s47r {text}

Returns text but green.

sq4sh {string1 string2}

Returns string1 concatonated with string2.

str1ng1fy {number}

Returns number as a string, represented using vowels.

/R33333{ea} @ prints 5
/R33333{/str1ng1fy{ea}} @ prints EA

ch4rC0d3 {string}

Returns the unicode number of the first character of string.

l3tt3r {string index}

Returns the character of string at index.

f1l3 {path}

Returns a string of the content in the file at path.

BR4P

Throws an error.

YeahNah

The equivalent of a try/catch is a yeahnah. Everything in the yeah block is run until there's an exception, in which case everything in the nah block is run. For example:

yeah ??!?1!
  /R33333{]this is printed first[}
  /D1V1D3{e a} @this throws an error since you can't divide by 0
  /R33333{]this is never printed[}
!?!!?? nah ??!?1!
  /R33333{]this is printed second[}
!?!!??

Cheating

If you just suck too much to completely use g4m3rscr1pt (or there's something you actually can't do) you can enter plain JavaScript like this:

I'M CHEATING <
  // Note: hello can't be used outside of JS since it has vowels
  const hello = "Hello, World!";
  console.log(hello);
> I'M NOT CHEATING ANYMORE

I had a lot of help from this playlist by Toby Ho and I was inspired to create an esolang from Truttle1.
