String Links 404

[felix-alonso]

The links to System.String and System.Text.RegularExpressions are 404'ing on this page:

https://fsharp.github.io/fsharp-core-docs/reference/fsharp-core-stringmodule.html

Seems like the format of the link changed:

https://learn.microsoft.com/en-us/dotnet/api/system.string?view=netcore-3.1

[baronfel]

it looks like this has (partially) already been fixed in FSharp.Formatting - the URL generation uses docs.microsoft.com: https://github.dev/fsprojects/FSharp.Formatting/blob/a9ecebc3db319f2a3d07f841755ffc61bbf936df/src/FSharp.Formatting.ApiDocs/GenerateModel.fs#L950.

However, this should be updated to use learn.microsoft.com instead as a root.

Separately, the https://github.com/fsharp/fsharp-core-docs repo should update to a more recent FSharp.Formatting and republish the docs to get the fix.

Hi Felix, are you interested in contributing here?

[felix-alonso]

@nojaf,

Possibly! I'm just getting started with F#. How could I help?

When I clone and build the repo, I'm getting an MS Build exception.

I'm running:

OS:

Am I doing anything obviously wrong?

[felix-alonso]

I think I've gotten past the build issue. I can run the documentation locally. I'm just not sure how I can verify that I've fixed the external documentation link.

I see that this Classic XML Doc Comments contains an external link, but it uses the other URL format. When I click on the link it redirects to the new URL format

Current: https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/xmldoc/
Redirect: https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/xmldoc/

When I look through the project it seems like there are half a dozen other references to that URL.

Should change all of the instances of docs.microsoft.com/ to learn.microsoft.com/?

Thanks for the help!

I'm just not sure how I can verify that I've fixed the external documentation link.

The fsharp core docs are here https://github.com/fsharp/fsharp-core-docs

You’d want to build that repo’s docs using the fsdocs tool built with your PR. You can build those docs following the Build Steps on the readme.

The key thing would be to clone the repos as described in the fsharp-core-docs build steps. Then make your proposed changes in the FSharp.Formatting repo and build fsdocs with your proposed changes. Then do

(from 'fsharp-core-docs')
FSharp.Formatting\src\FSharp.Formatting.CommandTool\bin\Release\netcoreapp3.1\fsdocs.exe watch --sourcefolder fsharp

It’ll pop up a browser with the fsharp docs and you can test the URLs.

@nhirschey,

I've been able to mostly follow the build steps. I had to run the following to spin up the website:

(start in 'fsharp-core-docs')
dotnet restore FSharp.Core

(make 'fsharp-core-docs/fsharp' and 'fsharp-core-docs/FSharp.Formatting' )
git clone https://github.com/dotnet/fsharp --depth 1 -b main
git clone https://github.com/fsprojects/FSharp.Formatting --depth 1

(build 'fsharp-core-docs/fsharp'; didn't take noVisualStudio flag)
pushd fsharp
./build.sh
popd

(build 'fsharp-core-docs/FSharp.Formatting'; didn't take build flag)
pushd FSharp.Formatting
./build.sh
popd

(from 'fsharp-core-docs')
FSharp.Formatting/src/fsdocs-tool/bin/Release/net7.0/fsdocs watch --sourcefolder fsharp

However, it doesn't seem to pick up any modules in fsharp project. See the docs below:

Similarly, clicking on any of the documentation links it just complains that the connection was reset:

Any clue what might be causing this?

Hello @felix-alonso, I just tried these steps on Windows and could view the API docs there.
So, maybe this wasn't designed to work on anything else than Windows. The workflows seem to support this theory.
I can help you with the fsharp-core-docs repository once the fix is available in fsdocs.

Should change all of the instances of docs.microsoft.com/ to learn.microsoft.com/?

Yes, I believe so, if possible maybe refactor things a bit so that we use "learn.microsoft.com/" as a single constant.

Thanks again for looking into this!

I just found out that the links to System.String and System.Text.RegularExpressions are actually coming from:

https://github.com/dotnet/fsharp/blob/979fa51c3440c3e32b56c579b030b9df5636f9f1/src/FSharp.Core/string.fsi#L10-L11

So, this would need a fix in dotnet/fsharp as well.

@nojaf,

I've marked this PR as ready for review. Thank you for your guidance in this process!

I just found out that the links to System.String and System.Text.RegularExpressions are actually coming from:

https://github.com/dotnet/fsharp/blob/979fa51c3440c3e32b56c579b030b9df5636f9f1/src/FSharp.Core/string.fsi#L10-L11

So, this would need a fix in dotnet/fsharp as well.

Looks like these are the correct links:

• System.String
  • Before: http://msdn2.microsoft.com/en-us/library/system.string.aspx
  • After: https://learn.microsoft.com/en-us/dotnet/api/system.string
• System.Text.RegularExpressions
  • Before: http://msdn2.microsoft.com/library/system.text.regularexpressions.aspx
  • After: https://learn.microsoft.com/en-us/dotnet/api/system.text.regularexpressions

So the change is something like s|msdn2.microsoft.com/en-us/library|learn.microsoft.com/en-us/dotnet/api|g and removing the .aspx.

@felix-alonso thanks! I've updated all the links at the compiler side: dotnet/fsharp#14774
Once, that is merged we can try and update https://github.com/fsharp/fsharp-core-docs
