How to get hy-mode to work?

[tkaryadis]

Can you add instructions how to install it to get auto-complete? I never used Emacs in the past.

I think its very important people to be able to start with hylang in easy way, i am stuck days now.
I added MELPA i found hy-mode i press install but nothing happened.

I use ubuntu 22.04, with hy 0.25 , thank you.

I think that for now you have to use hy 0.20 because hy-mode is not yet adapted to hy 0.25.

[tkaryadis]

ok thank you i can do that, but can someone explain what i should do, like step by step, because i am not Emacs user, it can help other people to get started with hy

[kovan]

I would install Doom Emacs and uncomment the line that adds hy support in the init.el file.

About the Python hy package, in your virtualenv do pip install hy=0.20.0

[tkaryadis]

Its ok for now i will not try that auto-complete, if someone sometime makes a guide that works, i will re-try it.
Because i am new to hy and to python(haven't used it years) and to Emacs, so its many new things.

Thank you for trying to help me, doom emacs looks cool.

i got this after installing doom

Also with pip install hy=0.20.0 i got this

Did you activate the virtualenv and run pip inside it?
In Emacs you also have to activate it, with M-x pyvenv-activate.
That's all tha comes to my mind now.
