What do you usually look out for when writing a C lexer? Please let me know in the comments

1 month ago, another developer and I decided to make a totally new programming language as a replacement to the old CRy-vm. We wanted it to be nicer than it and limit the use of ai.
Don't be surprised that we are still making the lexer, we don't have havea ton of free time to develop it fast anyway!

Here is the repository:

Iya-lang / Ciyac

The Ciya VM complete

Welcome to Ciya! (parser stage)

Welcome, dear reader!

Now, we're trying to make a new project called Ciya.

Ciya, a fast, cross-platform programming language from the Philippines/Vietnam written in C The name Ciya came from the word Siya, which means he/she in filipino/tagalog language We want Ciya to be a bigger and faster leap than its successor, CRy-VM.

For now, we're still in development, but if you have any ideas to share, we'll try our best to achieve them.

Wanna collaborate?

Please read our CONTRIBUTING file.

Essential tools:

GCC (Clang or Mircosoft C/C++ Compiler): for compiling code
CMAKE: For building the build files
MAKE (or other build systems like Ninja): for building the program
GDB(optional): For debugging code, or you can use the debugger in some IDE's
WSL(for windows, optional) for Linux testing binaries

Why we made the project:

What do you think about it so far?

Hi everyone! I kinda made a simple lexer, does anyone have feedback? I really appreciate it.

Does anyone have feedbacks in my lexer?

A few days to weeks earlier, me and a contributor decided to make a handwritten programming language. The language was called Ciya-VM. Since I'm a filipino, I named the language after the tagalog word Siya (she/he in english). We promise that no instant ai code generation happens in the project, that is exactly what happend to my last language (Ry2).

Here's the link to github btw: https://github.com/Ciya-VM/Ciya
And the mostly undeveloped website: https://ciya-vm.github.io/

I just turned Ry1 into Ry2

Ry1 was turned into Ry2 which literally is 60% more speed than Ry1 which is a tree walk interpreter while Ry2 is a bytecode based interpreter like python's.
I also fixed some bugs which existed in Ry1.

New language has been created

johnryzon123 — Wed, 18 Feb 2026 10:55:02 +0000

I made a new called Ry(also know as Ry's for You) this language has a c++ core which is fast while a tree walk interpreter it's foreach loop only took around 5 seconds in my laptop you can also test it in examples/speed_test.ry in ry's github repo
I am also working on a byte based interpreter for ry and foreach only took around 2 seconds in my laptop with it.
Ry has some really unique syntax like 'panic' instead of 'throw', 'unless' the opposite of if, 'do-while' the opposite of c++'s 'do-while' which ry doesn't have, 'attempt-fail-finally' instead of c++'s 'try-catch''.

Ry: A lightweight, user-centric programming language built for stability and developer experience

Ry (Ry's for You) 🌀

Ry is a lightweight, robust, and user-centric programming language designed with a focus on stability and developer experience. Whether you're building simple scripts or exploring language design, Ry is built to be helpful, colorful, and fast.

Key Features

Intelligent Error Reporting: Beautiful, color-coded error messages with caret pointers (^~~) to show you exactly where things went wrong.
Optimized Iteration: High-level foreach loops and range expressions (0 to 100) designed for performance.
Smart REPL: A dynamic interactive shell with auto-indentation tracking and colorized prompts.
Built for Stability: A memory-conscious C++ core that respects your hardware limits.

Performance

Ry is built to be efficient. In our internal benchmarks, Ry's native iteration outperforms standard loop structures:

Loop Type	Time (Lower is Better)
foreach	~5.0s
for	~10.0s
while	~11.0s

Installation

Ry comes with a built-in installer for Linux and Windows systems.
