F# and Jupyter

This implements F# for Jupyter notebooks. View the Feature Notebook for some of the features that are included.

.NET Interactive (alternative)

There's related project of .NET Interactive which was inspired by this one but a completly rethought approach with integrated package management, VS Code support, and variable sharing between languages. If you're moving to .NET Core support it's definitely worth checking out. There's a great video from cartermp demoing some of the features: https://youtu.be/_QnbV6CAWXc?t=1298

Getting Started

Docker

To run using a Docker container on Linux/macOS:

docker run -v $PWD:/notebooks -p 8888:8888 fsprojects/ifsharp

or with PowerShell on Windows:

docker run -v ${PWD}:/notebooks -p 8888:8888 fsprojects/ifsharp

The container exposes your current directory as a volume called notebooks where the files get saved. Open with

http://localhost:8888

and enter the token printed by the docker container startup, or set up a password.

Notes:

Add -p <your_port>:8888 if a different port mapping is required.
If using Windows you must enable file sharing for docker on that drive.

Azure Notebooks

You can use Jupyter F# Notebooks with free server-side execution at Azure Notebooks. If you select "Show me some samples", then there is an "Introduction to F#" which guides you through the language and its use in Jupyter.

Windows Local Installation and Use

Download Anaconda for Python 3.6
Launch Anaconda3-4.4.0-Windows-x86_64.exe (or later exe should work, file an issue if you have issues) Click through the installation wizard, choosing the given install location. At the 'advanced installation options' screen shown below, select "Add Anaconda to my PATH environment variable". The installer warns against this step, as it can clash with previously installed software, however it's currently essential for running IfSharp. Now install.

This should also install Jupyter: you may check this by entering 'jupyter notebook' into the Anaconda console window. If Jupyter does not launch (it should launch in the browser), install using 'pip install jupyter', or by following Jupyter instructions.
Download the latest IfSharp zip release
Run IfSharp.exe (IfSharp application icon).

Jupyter will start and a notebook with F# can be selected. This can be run via "jupyter notebook" in future

Troubleshooting

If the launch fails in the console window, check that the Anaconda version used is currently added to the path. If not, uninstalling Anaconda and reinstalling using instructions 1-

macOS Local Installation and Use

Install Jupyter via pip or Anaconda etc.
Install Mono (tested Mono 6.6.0)
Download the latest IfSharp zip release
Unzip the release then run mono ifsharp.exe

Jupyter will start and a notebook with F# can be selected. This can be run via "jupyter notebook" in future

Linux Local Installation and Use

Install Jupyter via pip or Anaconda etc.
Install Mono (tested Mono 5.18, "mono-complete" recommended).
Download the latest IfSharp zip release
Unzip the release then run mono ifsharp.exe (this sets up the Jupyter kernel files in ~/.local/share/jupyter/kernels/ifsharp/)

Jupyter will start and a notebook with F# can be selected. This can be run via "jupyter notebook" in future

Linux Local Installation (HDInsights)

Follow instructions to install or update Mono on HDInsights.
SSH into the HDInsights cluster.
Download the latest IfSharp zip release

# create ifsharp folder under /tmp
mkdir ifsharp
cd ifsharp
wget https://github.com/fsprojects/IfSharp/releases/download/v3.0.4/IfSharp.v3.0.4.zip
unzip IfSharp.v3.0.4.zip
chmod +x ifsharp.exe

From the Azure portal, open your cluster. See List and show clusters for the instructions. The cluster is opened in a new portal blade.
From the Quick links section, click Cluster dashboards to open the Cluster dashboards blade. If you don't see Quick Links, click Overview from the left menu on the blade.
Click Jupyter Notebook. If prompted, enter the admin credentials for the cluster.

[!NOTE] You may also reach the Jupyter notebook on Spark cluster by opening the following URL in your browser. Replace CLUSTERNAME with the name of your cluster:

https://CLUSTERNAME.azurehdinsight.net/jupyter
Click New, and then click Terminal.
In the terminal window cd into the /tmp/ifsharp/ folder and using mono, run the installer:

cd /tmp/ifsharp
mono ifsharp.exe

Back on the Jupyter homepage, click New and you will now see the F# kernel installed.

ifsharp's Issues

Not all 0mq client->kernel messages are handled

Currently, only a subset of the messages from the UI to the kernel are handled. However, everything seems to work just fine.

The unhanded messages need to be evaluated so it can be determined if they should be implemented.

Cannot run commands

I have just installed iF# as described in the readme. I then run the ipython notebook --profile ifsharp command, which starts up the server. At this point, all seems to be working fine. But when I open the Feature Notebook, the following is written in the console, and nothing really seems to work in the notebook itself.

Can anyone tell me what is going on? I should probably tell you that I am running OS X. I have a feeling this might cause the problems.

#N can be configured to only a single NuGet repository

It would be nice to be able to reference multiple NuGet repositories to support scenarios where local NuGet packages are needed.

fake install script issue

I get this error when running the cmd file. probably due to fake, I don't see versioning.
It works fine from VS though.

Installing kernels to wrong location on Mac

Description

We're installing the F# kernel to the wrong location for Mac. The root cause is that:

Environment.OSVersion.Platform

does not return Platform.MacOSX in the current version of Mono. Background to this:
http://mono.1490590.n4.nabble.com/Why-does-Environment-OSVersion-Platform-report-PlatformID-Unix-on-OS-X-td4038093.html

We'll need to perform the platform check in a different manner

Actual behavior

Jupyter doesn't allow you to load F# kernel.

Known workarounds

Copy the files yourself:
http://jupyter-client.readthedocs.io/en/latest/kernels.html#kernel-specs

#N NuGet referencing isn't supported in Include.fsx

It would be handy if #N were supported in Include.fsx. My particular use case is setting up a shared IFSharp installation that references an internal NuGet package and opens a few namespaces from that package as the shared default, rather than every notebook having to reference that package and specify the default set of namespaces to open.

Create Binary Release with Jupyter Support

Seeing as how we have Jupyer support now (#51) it seems like we're due for a binary release. Is there anything standing in the way of this?

NuGetManager errors out when there are no AssemblyReferences

Auto install UI scripts on version changes

UI scripts, custom.js, custom.css should be installed automatically when ifsharp.exe when these version of these files change.

Mono support for FSharp.Charting

It would be nice if the GTK version of FSharp.Charting is automatically used for Mono / Linux compatibility.

Beaker Notebook Support

Hi,

Is it possible to look into how you can get this to work with Beaker Notebook (http://beakernotebook.com/).

Installation instructions OS X/Linux

I tried to follow the installation instructions but first got stuck because setup.exe isn't a cross-platform way of installation. Then when doing the manual installation, on step four, it asks me to open the iF# sln file, but there's no such file to open as a result of the previous commands. At least not one that I could find.

how easy to extend IfSharp to other .NET languages?

"dict" not working

I believe this is because "dict" is defined as one of the types in IF# and masks the actual keyword:

let alphabet = dict [('A', 0); ('C', 1); ('G', 2); ('T', 3)]

returns:

error FS0041: No overloads match for method 'Dictionary`2'. The available overloads are shown below (or in the Error List window).

Switch from fszmq to netmq for easier cross-platform compatibility

It would be nice to not have to worry about native implementations of zmq. I think that ipython may require a certain version of the zmq protocol version. Version 2.0 IIRC.

build.fsx

Invoking "build Build" (build being the script calling Fake calling MSBuild ) does not seem to actually build the projects IfSharpConsole and Kernel, although going through VS for compiling the solution does compile it. can someone reproduce ?

Run in QtConsole with autocomplete

Hi!

Is it possible run IfSharp in IPython QtConsole?

Custom default visualizations

Loving this - great work guys!

Just wondering whether it is possible to register some custom visualizations for a type. For example, a Deedle frame?

Right now, if I reference Deedle and create a series I get a textual output. Would love for the default to be an HTML table for a Series or Frame.

e.g.:

open Deedle

series [ 1 => 2; 2 => 3]

val it : Series<int,int> = series [ 1 => 2; 2 => 3]

Only the last chart/expression evaluated is currently shown.

Currently we look into the FSI pretty printer for our output. However, F# suppresses output for all but the last evaluated expression.

There are many approaches to fixing this. The best in my mind would be to stick with the iPython style of having an explicit output function.

setups

Hello. I have a problem with this:
6 Open up the copied "ipython_config.py" file and change "..\bin\ifsharp.exe" to the path of your compiled ifsharp executable.
In ipython_config.py I dont have any path to ifsharp.exe. So, what I need to change?

Installation instructions are now outdated

We need to provide a link to the installer.

Restart behaviour Jupyter 4.1

There is new functionality around restarting kernels in Jupyter 4.1 (http://blog.jupyter.org/2016/01/08/notebook-4-1-release/#restartkernelandrunall). This isn't working cleanly with IfSharp.

Start a new kernel
Write some F# code
Trigger a restart
(nothing apparently happens… wait a few seconds)
Jupyter detects dead kernel and offers to restart
Actually restarts
Write some more F# code

This isn't a fatal problem but it's very irritating in practice.

Compulsory reference to (old version of) FSharp.Charting blocks reference of newer versions

I've been using Jupyter/Ifsharp in combination with FSharp.Charting (FSC) a lot recently. To make use of the newest features of FSC (histograms and bug fixes in my case), I've been building FSC locally. Annoyingly, in order to reference my local FSC build in a notebook, I've had to forcibly remove the existing compulsory reference to v0.9 of FSC in Ifsharp. Without doing this, it seems that the compulsory reference blocks my local reference.

Do others find this annoying? The compulsory reference is definitely more of a hindrance than a convenience for me.

I'd be happy to submit a pull request for the removal of the compulsory reference, but thought it best to garner opinions before doing this.

Automatically reference NuGet dependencies

I don't know how easy this would be to include, but I was hoping it would be possible to mimic the default behavior for the Visual Studio NuGet Package Manager. If you reference a packaged via #N the dependencies are not retrieved if not already downloaded. An example that has a few layers of dependencies would be #N "FsLab/0.0.13-beta".

Win 8.1 repeated "Kernel Restarting"

Win 8.1 x64 in a virtual machine, VS not installed, Anacoda/IPython/Latest installer as per Automatic Installation directions.

Initially when running IFSharp, it would crash when I tried to "Create new notebook". The error thrown was along the lines of unable to find libzmq.dll. I solved that by installing Visual C++ 2012 Redistributable Package here http://support.microsoft.com/kb/2019667 (I installed both x64 and x86, not sure if both were needed).

This solved the error with the specific message above, it now loops a few times restarting the kernel after "Create new notebook" is pressed with no other input. "Assertion failed" might be a clue, but it might also just be a side effect of restarting: https://zeromq.jira.com/browse/LIBZMQ-292 . Command line output follows:

Could not load FSharp.Core assembly

Hi, I'm trying to build from VS2012.
On my first attempt the projects are fussy because they can't resolve FSharp.Core 4.3.1. I tried deleting the references and re-adding them for IFSharp.Kernel and IFSharp.Kernel.Tests. When I create a new notebook I see this odd combination of errors: one still hunting for FS4.3.1 and the other unable to find FS 4.3.0. I've marked the new references to copy local. fwiw I would gladly upgrade to 4.3.1 if I could figure out where to find it- is it specific to VS2013?

Unhandled Exception: System.IO.FileNotFoundException: Could not load file or assembly 'FSharp.Core, Version=4.3.1.0, Culture=neutral

As a side note what is the purpose of the optdata and sigdata files in IFSharpConsole? Do they have a hard dependency on 4.3.1?

Thanks

NetMQ version upgrade breaks on Linux/Mono

Since the upgrade from NetMQ 3.0.11 to 3.3.2, Jupyter cannot connect or send commands to IfSharp kernel on Mono 4.4.

In the file "Kernel.fs" the debugger seems to lose the connection in
the socket.ReceiveMultipartBytes() function.
It runs the line let recvAll (socket: NetMQSocket) = socket.ReceiveMultipartBytes() twice and then the process stops talking with the debugger.
I added some printf statements before and after the call to ReceiveMultipartBytes, only the "before" message is printed, twice. These seem to be control messages.

So it looks like two control messages are received but then socket.ReceiveMultipartBytes is waiting forever.

Perhaps this zeromq/netmq#553 is related.

Problems with Include.fsx using Jupyter 4.1

I recently reimaged my machine, with only VS2015 installed (no VS2013). I found a workaround to get Ifsharp working, by changing App.config to use the latest MSBuild.

There is a problem with the automatic running of Include.fsx, which produces error messages in my log file:

2016-03-01 16:36:04 - input.fsx(8,1): error FS0082: Could not resolve this reference. Could not locate the assembly "FSharp.Data.TypeProviders.dll". Check to make sure the assembly exists on disk. If this reference is required by your code, you may get compilation errors. (Code=MSB3245)
2016-03-01 16:36:04 - input.fsx(8,1): error FS0084: Assembly reference 'FSharp.Data.TypeProviders.dll' was not found or is invalid

I was able to workaround this by commenting out the TypeProvider.dll reference in Include.fsx.

This raises the question about whether to automatically include DLLs using this strategy. There have been similar issues with including FSharp.Charting: #52

How to install IF# kernel for Jupyter Notebook?

Does IF# work with Jupyter Notebook? And how to install?

I use Linux, by the way.

Notebook is run in 32-bit even if Anaconda is 64-bit

The iFSharp notebook runs 32-bit by default, even if Anaconda is 64-bit. I got around this in a local build by removing the preference for 32-bit in IFSharp.Console and by linking to a locally built 64-bit assembly for libzmq.dll.

Perhaps 64-bit should be the default and have gcAllowVeryLargeObjects (mentioned by @Rickasaurus in email).

Windows 8 gives a rather serious looking warning when the installer is run.

I believe that this can be fixed by signing the installer with a proper certificate.

Kernel dies when triggering auto-complete and Intellisense does not work.

Hello and thanks in advance!

I'm running Windows 8.1 Pro x64 in Parallels VM and recently installed IfSharp. It looks really great, and I'm able to execute code and generate graphs.

Issue is that Intellisense does not work, and when i hit shift + tab to trigger auto-complete, the kernel dies. Below is my log - after the 2nd open system is when i hit . Anyone have any ideas?

As an aside, I'm rather new to windows, but when I execute .\ifsharp.exe --install from Powershell I get ifsharp program crash errors, including a ..\--install file not found...

Display type of things

Would it be possible to imlement showing the type of various parts of the code? For example the original F# interactive will display the type of anything that is not evaluated:

> Seq.find;;
val it : (('a -> bool) -> seq<'a> -> 'a) = <fun:clo@4-1>

ghci has the command :t expr to print the type of expr. Some IDE's display the type as a tooltip (that would need support selection so that you can choose what you want evaluated for type).

Thanks 👍

Display compilation errors as red squiggly lines

Send back compilation errors and display them as red squiggly lines when compilation happens. When the user hovers over the error, the error text should be displayed

Intellisense is not supported

Getting the needed data out of the compiler is straightforward, but we need to figure out a way to track the contents of all cells on the F# kernel side.

Fill out release notes

Let's start using RELEASE_NOTES.md for its intended purpose. The project's mature enough now.

Maintainer status?

Hi @Rickasaurus @prosconi ,

Would you like to bring on more maintainers to this project? I suspect we could recruit more maintainers via twitter?

Best

Can't get intellisense to work

If I create a new notebook and type open System. I don't get any pop-up. Do I need to do something to work it work?

Proposal: Dockerfile for Jupyter - Linux

Hello

Let me start by saying thank you for the wonderful effort put into building the F# kernel for Jupyter, it is a great and useful piece of work, especially on Linux where the tooling around this language is not as well developed as on Windows.

In my efforts to streamline my work I built a Dockerfile for getting started immediately with Jupyter F#. It is based on Anaconda3 and accepts connections from everyone on 8888. The notebooks get saved in a volume that can be mounted on running the image.
I'm guessing it could be useful for people who want to quickly take a look at how it works and don't want to install everything locally (by everything I mean Anaconda, Jupyter and mono), or update their already configured environment to support the versions we need for running the F# kernel.

I could bring the Docker file into this repo, if there's any interest in it. Currently I have it here along with a more elaborate explanation of how to use it.

Off the top of my head there are a few things I could tweak:

base it on something smaller than Anaconda3 (though my initial attempts to use minimal-notebook - the official image, have failed)
stop hard-coding allowed IP addresses and just pass the arguments to jupyter-notebook via the docker run
perhaps not clone the IfSharp repo inside the image (once built, re-building the image will not pull newer versions of the code because of the Docker cache), however not sure how to checkout a branch using the Docker context
etc

Please do let me know if you think it would benefit the project and I'll work on it a bit more.
Thank you.

Timeout waiting for kernel - Linux

Hello,

Trying to run the last version of the Jupyter branch on Linux (amazon linux).
Tried both the v3 alpha binaries and built the last source code version.
The kernel won't work at all.

[I 19:08:36.548 NotebookApp] Kernel started: be59d74b-c0ed-4190-9af3-990f1eb783cb
[W 19:08:46.623 NotebookApp] Timeout waiting for kernel_info reply from be59d74b-c0ed-4190-9af3-990f1eb783cb

This version would solve the problem for me : https://github.com/FilippoPolo/IfSharp
Any chance this can be merged in the main project ?

Thanks!

no mouse-over type signatures

Description

I don't see any examples of mouse-over type signatures in the README or Feature Notebook, so I'm not sure if I screwed up the installation or if they are not implemented.

Repro steps

Please provide the steps required to reproduce the problem

Clean install of IFSharp on Windows 10
Mouse-over assigned value

Expected behavior

I expect to see a tooltip pop-up with the value's type signature as I would in Visual Studio

Actual behavior

Nothing happens

Known workarounds

Syntax Coloring Needs Improvement (CodeMirror)

Currently the syntax coloring is done via a hacked up Scheme variant. This should be reworked for F# explicitly via the spec or a port of an existing implementation.

Intellisense box won't go away

The intellisense box should hide itself when another cell gains focus

Any way to customize the nuget server settings?

So we go to an internal repository by default?

Jupyter / IPython 3.0 version

For Anaconda the latest version of IPython is 3.0. I tried using IfSharp and was sucessful in getting cells to evaluate with the IfSharp kernel, but intellisense/code completion does not work. I do not know how much work it is to get this project upgraded, but thought I should submit a placeholder issue.

Use Net MQ for compatibility with Linux / Mono

The current solution for zmq is to use fszmq which uses native binaries. Net MQ is a pure .NET implementation of zmq.
