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.

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 :)))

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.

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)

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

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

I'm still experimenting with the latter.

This if statement does not work:

if arr@i == arr@j then # do_something

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

a = arr@i
b = arr@j
if a == b then # do_something

Update See the comment below, which is way better.

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.

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).
