intellisense not working on fsx file

[jackfoxy]

Describe the bug
mouseover intellisense not working for fsx file

To Reproduce
Steps to reproduce the behavior:

1. use https://gist.github.com/jackfoxy/ba315d2190ae563f5a7d40cf72428fcf
2. download gist saving to something.fsx
3. open file
4. hover over anything, and nothing happens (see F# Output)

Expected behavior
Expect to see similar pop-up information to Visual Studio, where opening this file and seeing intellisense works.

F# Output

If you want to run scripts with only SDK installed have you set FSharp.useSdkScripts option to true?

[jackfoxy]

I just set that setting.
If the file is named something.fsx, and it is the only file open in Code, Ionide does all the syntax colorization and the "FSI: send file" gadget is enabled and works, but still no tooltip pop-ups on hover.

[baronfel]

Try closing the file, reloading the window, and then reopening the file.

K, I think this is a timing issue because the default setting is netfx, but then the users setting for useSdkScripts is sent after the file is open but before typechecking is complete, so the invalidation that fires doesn't clean out the typecheck results. This is one reason why I want to move to netcore scripts as the default sooner rather than later.

[jackfoxy]

I don't understand what you mean by reloading the window...
I closed file, I closed Code. I reopened Code. I opened file from recent, still no tooltips.

[baronfel]

@jackfoxy reload in this case means using the 'reload window' command from the command palette, but that's just a shortcut for the close + reopen procedure you mentioned.

[jackfoxy]

Thanks. I learned something. Still no change.

[Krzysztof-Cieslak]

Sample gist just works of me without any problems

[jackfoxy]

Still no hover-over tools tips for me, now on Ionide 4.4.5.
Maybe I have a conflicting extension installed.

[nhirschey]

I have a project where I have the same issue with scripts whenever I try to use netcore fsautocomplete. .fs files work with tooltips, but .fsx files do not.

Ionide only works with scripts when I use the .net fsautocomplete version. (Windows, 3.1 netcore and .net sdk versions).

[Ellyll]

This also happens for me on Ubuntu 18.04.4 LTS, netcore 3.1.102, Ionide-fsharp 4.6.3, VSCode 1.42.1.

[brpratt]

Does the problem go away if you set FSharp.dotNetRoot to the base path indicated by dotnet --info? I recently saw a similar problem that was resolved by properly setting this value:

#1306 (comment)

[jackfoxy]

@brpratt I see my FSharp.dotNetRoot is not set to anything and dotnet --info is pointing to the lastest 3.1.101 sdk.

But retesting on current Ionide shows the problem has gone away, probably in some intervening update. So I am closing.

[mastoj]

I'm having the same issue on Windows, did you figure out what the actual problem is? I just switched back to Windows after being on Mac for a couple of years, maybe I regret that soon :).

@mastoj I don't use Ionide very much, but when I do it is always on Windows.
I currently have the 3.1.201 SDK as the most recent, and I retested my test case at the top of this issue, and it still works for me.
My VS Code is up to date, as is Ionide.

[mastoj]

Hm. I guess there is a setting or something I haven’t set then.

Not sure it helps for the issue, but here is the log from the dev tools in code:

I have the same issue.

Created a file hello.tsx typed in
let a = 10
And when tried to hover over a got this message in the output console.

  [Error - 12:02:38 AM] Request textDocument/hover failed.
  Message: Cached typecheck results not yet available
  Code: -32603

@akibmaredia, no guarantees, but maybe check here? #1381
