calysto_hy's Issues

Is it possible to start up kernel with pre loaded hy libraries?

Hi,

this is a question rather than bug issue.

I'd like to require and import different macros and libraries on every kernel start up. Is it possible to define custom hy / python libraries somewhre so that they will be automaticly loaded on every start up of the calysto hy kernel?

macros not working in PR

The current PR fixes the main problems reported in other issues.

pip install git+https://github.com/fergusq/[email protected] --upgrade

You may need to add --force-reinstall but be careful as that is recursive to all dependencies ☹️ The default code completion works. jedhy hasn't been updated so it won't work even if you install jedhy.

However, macros outside the default don't work. For example,

This seems to have happened once before...

#16

but I can't figure out how this relates to the newer version (0.24+) of Hy. :(

There are no code autocompletion for object attributes/methods?

When I use this kernel, I found that the object's attributes/methods can't get the completion.
like this:

but in raw hy-repl, I can get the completion:

I should turn on it by some configuration, or this is not supported for now?

Change colors

Hi there is a way to change the syntax colors the default blue is too dark and you can barely see it

I'm using alacritty with the default colors config.

Installation is broken

Presumably because of the changes in Hy?

In a venv, I followed the readme instructions,

%matplotlib inline does not exist

I realize this might be a metakernel issue, so feel free to redirect me if that is the case. I am trying to run a scientific Python stack with pandas, matplotlib, etc. with this notebook, but it seems like I can't plot inline.

Any directions on where to start looking? I'd be happy to help contribute a patch.

Function defs don't have return value when multiple expressions in cell

I am having the following issue:

If I run the following code in a separate cell:

(def a '(+ (+ 2 3) (* 3 4)))
(def b "bbb")
a

Out[]: displays nothing.

Then I run it like this:

(def a '(+ (+ 2 3) (* 3 4)))
(def b "bbb")
a
b

Out[]: displays ('+' ('+' 2 3) ('*' 3 4))

And the following code:

(def a '(+ (+ 2 3) (* 3 4)))
(def b "bbb")
a
b
a

Evaluates to:
'bbb'

This behaviour is not present in a raw Hy interpreter opened in console.

The version is... the last, I suppose. Python version is 3.5.2.

Tagged release + PyPI upload?

Any reason not to do this? I've been using the kernel and apart from lacking %matplotlib inline support (which means I sadly can't use it for plotting on Jupyterhub) it seems stable and functional.

I'm not personally familiar with the PyPI release process, but I'd be happy to take it on if you think it's ready.

Can't evaluate python from Hy

The following, however, does work:

(hy.eval '(py "print('hello')"))

Looks like a problem with the kernel rather than with my particular setup.

Ipywidgets support

Good day for everyone!

It would be great if one was able to use ipywidgets in Calysto. As far as I understand, the side responsible for displaying widgets is jupyter kernel and this feature is not implemented yet in Calysto (though I might be missing something).

Here's what I get when trying to display a widget object:

While the same code (literally translated) in python works perfectly fine for me.

Thanks for your attension!

Some code does not run

Sorry for this very general issue title. I just tried your kernel with some examples from the Hy language documentation and I thought it might be most useful, if I shared that notebook with you, where it prints the errors in red as an output to a code cell. I don't really know what the problem is with it or with what code it happens and with what code it doesn't.

So here is the repo for the test notebook: https://github.com/ZelphirKaltstahl/hy-kernels-test-notebook

Cannot open Tutorial notebook in Jupyter

I downloaded the Tutorial notebook from your repo, but I cannot open it in my Jupyter. A modal is shown with the following message:

Unreadable Notebook: /home/xiaolong/development/Hy/Tutorial.ipynb NotJSONError('Notebook does not appear to be JSON: '\n\n\n\n\n<html lang="en...',)

Integrate jedi and jedhy as autocompletion

There is a new completion module from the hy-mode for emacs written in hy. I

https://github.com/ekaschalk/jedhy

also Jedi could be used for completion, as it is also default now for the ipykernel.

https://jedi.readthedocs.io/en/latest/docs/features.html#recipes

Cannot import name `_compile_table`

With Hy version 0.15.0 and Metakernel version 0.20.14:

$ python -m calysto_hy install --help

ImportError: cannot import name '_compile_table' from 'hy.compiler'

I went into hy.compiler.py file, and I don't see anything named _compile_table. Was this a recent breaking change to Hy?

edit: I see that _compile_table is present in Hy 0.14.x, so yes it looks like an API change

Hylang Test.ipynb - In [32]: Show users how to properly unpack keyword arguments

In Hylang Test.ipynb:

In [31]:
(defn optional-arg
  [pos1 pos2 &optional keyword1 [keyword2 42]]
  [pos1 pos2 keyword1 keyword2])
  ...
In [32]:
(setv args [1 2])
(setv kwargs {"keyword2" 3 "keyword1" 4})
(optional-arg args kwargs)
Out[32]:
[[1, 2], {'keyword2': 3, 'keyword1': 4}, None, 42]

Which is fine, but probably not what the user wants. Can we add an input after this that will show them how to properly unpack these arguments?

In [32]:
(setv args [1 2])
(setv kwargs {"keyword2" 3 "keyword1" 4})
(optional-arg (unpack-iterable args) (unpack-mapping kwargs))
Out[32]:
[1, 2, 4, 3]

I can make a pull request if you approve.

P.S. Thank you for this work. I threw this into a JupyterLab 3.0 notebook on something called myBinder.org 40 minutes ago and the experience has been ridiculously smooth and enjoyable. Cheers!
