Sicht, A New Programming Language

Hi. I’ve been working on a programming language called Sicht.

It started as a personal project because I wanted to better understand how programming languages work internally, things like lexing, parsing, interpreters, and compilers. Over time the project grew into a complete language with its own runtime, compiler pipeline, and standard features.

Sicht focuses on clear and readable syntax using structured English-like expressions.

Example:

start

set age to 20

if age is greater than 18 then
print "Adult"
otherwise
print "Minor"
endif

end

The language currently includes things like:

integers, floats, booleans, strings

lists and dictionaries

functions with parameters and defaults

generators

conditionals and loops

modules and libraries

file I/O

REPL support

a VM backend and executable packaging

Programs are written in .si files and executed with the interpreter:

sicht.exe example.si

This project has mostly been about learning how languages actually work under the hood and experimenting with language design.

If anyone is interested in taking a look or giving feedback, here’s the repository:

Gotharden / sicht-lang

Install from GitHub

1. Click on the button "<> Code"
2. Download it via "Download ZIP"
3. Extract it to a folder (PATH MUST LOOK LIKE C:\Sicht )
4. On powershell: run command: cd C:\Sicht
5. Run installer:

powershell -ExecutionPolicy Bypass -File .\installer\install.ps1

5. On the same terminal:

./sicht.exe version

Quick Start (2 Minutes)

Run included example:

./sicht.exe run examples/example.si

Open REPL:

./sicht.exe repl

Create hello.si:

start
set x to "Hello, World!"
print x
end

Then run and compile:

./sicht.exe check
