An easy-to-learn, dynamic, interpreted, procedural programming language

Last update: Oct 17, 2022

Overview

Gen Programming Language

WARNING!! THIS LANGUAGE IS IN DEVELOPMENT. ANYTHING CAN CHANGE AT ANY MOMENT.

Gen is a dynamic, interpreted, procedural programming language.

Almost everything (for, if, and more) can be written in just one line. But it is pretty wordy, so it's also easy to learn.

TODO List

Built-in functions
Map (dictionary in Python)
Import other files
Reading files with extention .gen (meaning allowing multi-line statements)

Installation

git clone https://github.com/Gen-lang/Gen.git
cd PyGen/pygen

Then you can run Makefile:

make install

Then you can use gen:

gen some_file.gen

Hello World

println("Hello World")

Example

For examples, see examples directory.

# Fizzbuzz

for fizzbuzz = 0 through 51 then
	if fizzbuzz % 3 == 0 and fizzbuzz % 5 == 0 then
		println("fizzbuzz")
		continue
	elseif fizzbuzz % 3 == 0 then
		println("fizz")
		continue
	elseif fizzbuzz % 5 == 0 then
		println("buzz")
		continue
	end
end

Contributing

Contributions are welcome! Especially, I need an assist on Makefile to make Gen available to Windows users.

Reports

If you found a bug, please open a new issue and paste the error message and your code that caused the bug.

Credits

I learned a lot from this series and T# programming language.

Make another gen implementation(Optional)

I think it will be good to have another gen implementation in other languages since the pygen implementation can be slow and it is also memory inefficient. I do think it needs to have a VM(virtual machine, python, java and other more languages use this), JIT(just in time) compiler or other more like AOT compiler(ahead of time). I think a VM is enough for portability since JIT compilers can compile to the target architectures that they only can support. This is only optional since performance and memory usage sometimes don't matter. Please correct me if I'm wrong.

Suggestions for the import feature
My suggestions for the import feature:

Make it a function like:

import("library file")

or just a keyword:

import "library file"

Make import return a map of the library

"library file" should be the path to the file

That's all :)))

Library readline not available for Windows
So I tested pygen on Windows. I needed to install readline in order to make gen.exe work. When installing readline on Windows using:

pip install readline

It does not work. One of the errors:

error: this module is not meant to work on Windows

That's all.

Building for Windows (Needs some fix, See comments below)
The issue is there are no builds for Windows. You can do that with simply this:

pip install pyinstaller pyinstaller ./main.py --onefile COPY ./dist/main.exe ./pygen.exe

Python's CLI is the same as Python Linux build CLI. Pyinstaller needs to be in windows in order to build it to .EXE file. So it's up to you now on how to build it on windows while on Linux. You need to add it on PATH environment variable though if you want to access with only "pygen" and not the whole path to the application, which I don't know how.

I'm not an expert on Windows so I might be wrong.

(Nice programming language btw)

Iterate an array
I just wanted to ask you guys if creating another loop just for arrays:

iterate arr as i then println(i) end

Or should I just create the in keyword?

for i in arr then println(i) end

About the import function

Currently, this is how to use the import function:

import("examples/bubble_sort.gen")

arr = bubble_sort([12, 43, 23, 44])
println(arr)

But would you prefer something like this?

imported = import("examples/bubble_sort.gen")

arr = (imported@"bubble_sort")([12, 43, 23, 44])
# or if possible, I may make it like this:
# arr = [email protected]_sort([12, 43, 23, 44])
println(arr)

I'm still experimenting with the latter.

If statement does not work with complicated variable access
This if statement does not work:

if [email protected] == [email protected] then # do_something

So, to solve this, just assign them to new variables for now:

a = [email protected] b = [email protected] if a == b then # do_something

Update See the comment below, which is way better.

Gen extend standard library

The gen standard library is a bit small since it only has limited features. I think it will be good for it to have file I/O. You should also store file I/O functions in a "file" global map.

That's all.

Implementation in Crystal lang

I do think Gen written in Python is slow, so I think creating an implementation of Gen written in Crystal is nice because it is fast, and its syntax is similar to Ruby (which I don't know much tough).
