importing hyrule

[esakilpi]

I have been trying to import collections.assoc from hyrule, but I always get the same error. Even with (import hyrule).
I guess there is a bug in macrotools.macroexpansion-all that prevents the import?

This is the error message:

hy.errors.HyMacroExpansionError: 

  File ".../lib/python3.8/site-packages/hyrule/macrotools.hy", line 113
    (cond [(in (get form 0) '[unquote unquote-splice])
                      (+quote -1)]
                     [(= (get form 0) 'quasiquote) (+quote)]
                     [True (traverse form)])]
    ^^

Which versions of Hy and Hyrule are you using?

This seems to work in a virtual env:

(hy-dev) gabriel@linuxstudio:/tmp$ hy
Hy 1.0a4 using CPython(main) 3.10.4 on Linux
=> (require hyrule.collections [assoc])
=> 
=> (do (setv collection {}) (assoc collection "Dog" "Bark") (print collection))
{'Dog': 'Bark'}
=> 

Here's the environment:

(hy-dev) gabriel@linuxstudio:/tmp$ pip list

You can upgrade your versions of hy and hyrule with:

pip install --upgrade --pre hy hyrule

[esakilpi]

I thougth about that, but I think I'm using the latest version of both. Upgrading does not change the versions. Could it be that my python version is too old?

pip list | grep hy
hy                           1.0a4+183.gb3920666
hyrule                       0.1

Hy 1.0a4+183.gb3920666 using CPython(default) 3.8.1 on Linux

[Kodiologist]

It looks like you're using Hy master but Hyrule 0.1. You need Hyrule master.

[esakilpi]

I tried to install hyryle master like this but I got version 0.0.0

pip install git+https://github.com/hylang/hyrule.git@master

[gabriel-francischini]

IIRC, version 0.0.0 in the master just means it's a yet-to-be-released version. Does the (require hyrule.collections [assoc]) still throws even with it?

Python 3.8 is almost 3 years old now, but it shouldn't be the issue. You can use Miniconda (or virtualenv) to replicate the environment that I used, in order to try to rule out issues related to that python version:

source activate base ; conda activate base
conda create --yes --name replicated-hy python=3.10
conda activate replicated-hy
pip install --pre hy hyrule
hy

[esakilpi]

Yes, it works now. Thank you very much. import did'nt work, it doesn't recognize hy macros, but require does. I found the reason in the hy manual.
