does debugging make use of launch.json ?

Hello folks, I'm using .netcore on MacOS but and I've set Iodide to use .netcore but can't get the REPL to work

@s164158 I did the same, but without the final '\', and it worked (sort of). I can run FSI, but I still don't have Intellisense

hi folks, it seems as if Ionide defaults to the 32bit FSI, I have example rojects that have 64bit native libraries and I'd like to enable end users to simply git clone, open in Ionide, then run script in FSI without having to first change their worspace settings to the full path of FSharpAnyCPU. Is there any way to do this currently?

Hey guys, I still have this issue here ionide/ionide-vscode-fsharp#949 and have had it for a week or so now. Anyone know how to get around it?*

I am just starting out learning programming with F# via Gareth Hubball's Twitch videos. He's on a PC, I'm on a Mac, and when I installed VS Code and Ionide-fsharp, I got an error message about Mono. I figured out what that was and installed it, but now I still get the following message (and I can't figure out how to fix it): "Consider using the .Net Core language services by setting FSharp.fsacRuntime to netcore"

I've Googled and Binged and I'm still stuck, so any assistance would be appreciated. Cheers!

@Tlingit

@Tlingit I fixed it! Thanks to @cowlike; your last comment to @fergusmeiklejohn was what gave me the missing bit of information I needed to figure out my problem. :-)

I just added the Ionide F# extension to VSCode and it's not recognizing a package I added with dotnet add package. The project builds fine, but Ionide is saying that the package FParsec (which is what I added) is not defined.

I'm very confused so was hoping someone who knew what they were doing could help :)

some projects in my solution show "Status: parsed correctly" but the tree is empty in the ionide tab, other projects are all there, any idea what causes this?

(+ (* 1 2 3 4) 5 6 7)

@cowlike

@vgel I found that happening a lot with my vscode (seems like it gets better or worse with different updates) but I started cleaning the build output with the following hammer, which usually cures it: rm -r `find . -type d \( -name "obj" -o -name "bin" \)`

From the project root where the sln file sits, of course

PinkyBrain

@PinkyBrain_gitlab

it happens on both multitarget and singletarget projects, and both on projects with only f# refs as well as projects with f# and c# refs, so im ruling that out

Also, im using the sdk proj format on both the projects that load correctly and those that don't. The only clue is that it looks only the simple and small projects are loading

PinkyBrain

@PinkyBrain_gitlab

Nevermind, sorry, seems restoring the projects and waiting patiently is the answer

PinkyBrain

@PinkyBrain_gitlab

I see DU cases as just regular text, is there no syntax highlighting for them or is this configurable somewhere?

I am getting following error in Fable-Elmish project

Problem reading assembly 'c:\..\bin\Debug\netstandard2.0\DataLibrary.dll': Build was not evaluated, expected the results to be ready after 'Eval' (GetCheckResultsAndImplementationsForProject, data = ("FinalizeTypeCheck", [|Id 1007; Id 1008; Id 1009; Id 1010; Id 1011|], Id 1013,
 false, None)).

What does this mean?

I have reinstalled ionide and I still get the same error

Stefan Liebig

@StefanHub

Just starting with F#. I tried to use VS-Code/ionide with the mono runtime for windows. Is this possible at all?

Zane D. Purvis

@zanedp

@sandeepc24 That path doesn't make sense to me. The C:\..\ part is indicating one directory above your C: drive which doesn't make any sense.

Sandeep Chandra

@sandeepc24

The issue was with me using netcore for ionide, after reverting to net this error is gone.

Ionide fsharp is working as intended, except I can't seem to get autocompletion, any of you guys know why?

I'm on Atom

Fergus Meiklejohn

@fergusmeiklejohn

@JNLanthanide on VSCode I usually have to build the project to get autocompletion

Hi , is anyone here running vscode + ionide in nix/nixos?

this is my shell.nix

Solved it by adding a settings file with FSI path :)

Hi I was able to start default SAFE app with a nix package manger building the enviorment : https://github.com/countoren/FSharpBase check out shell.nix. But somewhy vscode is not able to load the Server project throwing: [Extension Host] [IONIDE-FSAC] Cannot execute simplifiedNames, File '/Users/oren/Desktop/fsharpTest/src/Shared/Shared.fs' not parsed .

and [IONIDE-FSAC] Cannot execute recordStubGenerator, File '/Users/oren/Desktop/fsharpTest/src/Server/Server.fs' not parsed

ps the Client project works just fine

and everything runs from the terminal

Hi, what settings do you guys use for Ionide on WSL on windows?
Specifically, how do you tell Ionide to target dotnet tools on mono/Linux rather than VS2017? And how do you tell if it is?
So far, I use these related settings:

"terminal.integrated.shell.windows": "C:\\WINDOWS\\System32\\wsl.exe",
"FSharp.fsacRuntime": "netcore",
"FSharp.monoPath": "/usr/bin/mono",

I'm getting squiggly lines/errors on the minimal fable project and files missing in the F# explorer, and wondering if there's a setting in File-Preferences-Settings-Extensions-FSharp configuration that might fix it.
Cheers!

Has anyone experienced problems with function signature only in script files (.fsx)?

I am with ionide-fsharp 3.30

Hi - how do I configure the list of msbuild options shown in the 'F#: pick msbuild host' option selector? I have several dotnet sdk's installed and to specify the path to that version of the sdk. At the moment I can only see it pointing to ~/.dotnet. But I have the SDK installed in ~/code/dotnet/2.1.403.... How can I tell it I want to use the dotnet executable from ~/code/dotnet/2.1.403?

This page is a ghost town. You would think F# would have an active forum community going by it's actual quality as a language and it's huge backer, at least on a par with Reason/Julia /Nim. The Slack channel is as good as it gets...
