F# and Fable (Python) support for Jupyter
Fable Python is an F# kernel for Jupyter based on Fable and IPythonKernel. Fable is a transpiler that converts F# to Python (and JavaScript).
This work is work-in-progress and related to
Install
git clone https://github.com/dbrattli/Fable.Jupyter.git cd Fable.Jupyter dotnet tool restore dotnet restore dotnet run InstallKernel
Usage
You can use Fable Python in the Jupyter notebook by selecting the "F# (Fable Python)" kernel. To start the kernel run:
dotnet run Jupyter
The process currently needs to be running while using the notebook. TODO: see if we can do it the other way around and start dotnet from Python instead.
Magic commands
You can inspect the generated Python code by executing %python
in a cell:
%python
You can inspect the maintained F# program by executing %fsharp
in a cell:
%fsharp
F# Program
The kernel works by maintaining an F# program Fable.fs
behind the
scenes. This program lives in the src
folder.
Sometimes the generated F# program might become invalid because of the
submitted code fragments (this happens with a Python notebook as well).
The way to recover is to reset the kernel. That will reset the F#
program that is running behind the notebook. To reset the kernel select
on the menu: Kernel -> Restart
or Kernel -> Restart & Clear Output
.
If you need additional package references you currently need to add them
manually to the Fable.fsproj
project file. TODO: handle #r nuget "...
commands from within the notebook.
