Modu is a simple and fast interpreted programming language.

Updated Project: It has been rewritten from scratch to fix major issues in the parser, while also introducing new features like way better error messages

This project uses AI

gh copilot for debugging and inline completions

Cyteon

Added back fancy errors to the runtime. They were inititally removed cause i wasnt sure how to implement them, but ended up adding a vec with spans where the index matches instructions. So i can fetch span X to get span for instruction X. Also fixed some minor bugs

Implemented WAY better FFI. It now dosent require the library to have modu_ffi headers or libs or wtv, and can work with pure ffi libraries. The image demonstrates using raylib in modu via FFI

Modu v3

Cause modu is pretty slow rn, im going to rewrite it to use a bytecode vm instead. Currently i have written a really really simple compiler and vm, that can do some basic stuff. Rn it can define variables and run internal functions.

  • Implemented while loops
  • Implemented else if branches

Modu v2.5.0

Primarily a math update, but i also rewrote the entire repl to have way better UX, and also implemented syntax highlighting in the repl.

Math additions:

  • *, /, %, and ** operators to the base language
  • added math.rand
  • added math.sqrt
  • added math.round, math.floor and math.ceil
  • added math.PI and math.E

Modu v2.4.0

Added:

  • .split(""), .len() and .replace(a, b) functions on strings
  • a.max(b) and a.min(b) on floats and integers
  • .join("") on arrays to join into a string
  • Accessing chars in a string, example: "abc"[1] equals b

In addition, nightly rust is no longer required for installing modu via cargo or contributing to modu

I was originally trying to make modu a compiled language too, but it didnt end well. I tried to do it via embedding code with a simple runtime. it worked but was incredibly bloated.
In addition it would severly limit platforms modu could be built for, as i would have to go through the pain of compiling the runtime for each arch and os, along with modifying modu to include those runtimes.
I have decided to scrap this idea, but the code will remain on the “building” branch.

  • Iterating on arrays in for loops
  • .keys() and .values() functions on objects
  • Properly printing functions
  • .close() on files

And:

  • Changed for loop syntax from n = x..y to n in x..y
  • Made error messages if u try to run an non-existent file
  • Fixed json parsing for arrays

I have been working on a bunch of site improvements

  • I have fixed some issues in docs
  • I have rewrited a lot of the site design to be the new theme
  • I have ported almost the entirety of modu to web using webassembly so the web ide now runs fully in the browser and does not depend on any server. Eventually ill use this to make input() work in the browser, and maybe even the http package!

Implemented FFI, still same imlementation as before but im looking into making it better. Also implemented the built in cryptography library, and fixed some bugs and examples. Have decided to ship modu 2.0 without file io, and some of the math package missing. But this will be added back in 2.1 or 2.2. As i have implemented everything back, all integration tests pass! HTTP tests dosent work cause httbin is down rn 😭

Implemented:

  • Arrays and accessing with variable[], works with both array[index] and object[“key”]
  • Fancy error messages if rust panics (should never happen though)
  • Importing installed modu packages, ensuring the packages can also import other files they came with

dude i love your project, im also building a lang!

Cyteon

Implemented the http package again, along with the json package. You can already see advantages of the new parser, with the long chained expressions as seen in the bottom of the screenshot. Also implemented objects/json again, and made the functions a little better. Like instead of json.stringify(obj) its obj.to_string()

Implemented:

  • File imports
  • Internal packages (uuid, time, os, encoding and partially math)
  • AST: modules, property accesses and improving calls, so you can do stuff like abc.abc() or abc()(), etc

Because the parser for modu is kinda shit, i have begun the rewrite. Currently it can parse “let x = 1;” or any other int or identifier. But i also added really fancy error messages.

This ship is for modu v1.1.0 - v1.3.0.
Contains a lot of improvements, bug fixes and some new packages

Cyteon

So i was originally just gonna implement some package improvements, but i found so much wrong in the language. I ended up:

  • Add examples for all math functions, and add all to docs
  • Add UUIDv7 to UUID package
  • Add some missing things to the vscode syntax highlighting
  • Properly implement arrays in the AST, instead of an cursed package someone made an PR for a while ago
  • Added MD5 to cryptography package
  • Deprecated time.now and added time.now_unix, time.now_utc, time.now_local, time.to_rfc_2822 and time.to_utc_date_time
  • Fixed context not being passed to basically every function in the math package, which was essentially bricking it
  • Removed the “line” property from a lot of AST elements that didnt need it
  • Made the lexer include string data, int data, float data and bool data, instead of me doing lexer.slice()… everywhere
  • Fixed an bug on the docs where the sidebar was scuffed

  • Bcrypt
  • Argon2
  • Scrypt

Implemented for loops, and infinite loops, along with break to stop infinite loops and to prematurely exit for loops.

Infinite loops are as easy as

loop {
    print("kaboom");
}

And for loops are as easy as

for n = 1...5 {
    print(n);
}

yipeee

Cyteon

Overhauled FFI to be way better

  • Cleaner support in modu
  • Supports strings, integers, floats, ints and null arguments (only strings before)
  • Supports string, integers, floats, ints and null returns (only strings before)

Old:

import "ffi" as ffi;

ffi.call(path, "hello_world");
print(ffi.call(path, "one"));
print(ffi.call(path, "add", 5, 2));
print(ffi.call(path, "string"));
ffi.call(path, "print", "test");

New:

import "ffi" as ffi;
let lib = ffi.load(path);

lib.hello_world();
print(lib.one());
print(lib.add(2, 5));
print(lib.string());
lib.print("test");
