VsVim for Mac: Does not activate for certain filetypes

Created on 29 Mar 2020  路  22Comments  路  Source: VsVim/VsVim

Describe the bug

VsVim 2.8.0.5 does not activate when opening certain filetypes in Visual Studio 2019 Community for Mac. Filetypes tested: .config, .fs, .resx, and .xml.

To reproduce

Steps to reproduce the behavior:

  1. Install Visual Studio 2019 Community for Mac version 8.5 (build 3183), VsVim 2.8.0.5, and Fabulous (dotnet new -i Fabulous.XamarinForms.Templates)
  2. Clone https://github.com/VsVim/VsVim and open its solution in VS
  3. Create or open a new file with one of the file extensions listed above
  4. Observe that VsVim is not active for its window (i.e., cursor is not in normal mode and no bindings work)

Expected behavior

VsVim should work normally when editing files of the said filetypes.

Environment

  • Visual Studio version: 8.5 (build 3183), Mac
  • VsVim version: 2.8.0.5
  • Programming Language: C#, F#
  • Check(Type 'x') any that are installed:

    • [ ] ReSharper

    • [ ] Visual Assist

Additional context

  • VsVim activates properly on the following filetypes (nonexhaustive): .cs, .pkgdef, .txt, .vsct, .vsixmanifest
  • If VsVim is currently activated for an open file, it will stay activated even after the said file is renamed with a nonworking extension (e.g., AssemblyInfo.cs to AssemblyInfo.fs); this persists until the file is closed and opened (VsVim will not activate during reopening)

Most helpful comment

The issue is because .config, .fs, .resx, and .xml file types are using a different editor and VsVim isn't compatible with the older editor.

This is slated to change in VSMac 8.7

For now, you can install this older Vim extension that works with the old editor. Install via Visual Studio -> Extensions -> Install from file

Alternatively, you can install this newer preview version of VSMac that uses the new editor for F# https://xamarin-downloads.azureedge.net/uploads/40tmghe3ng5/VisualStudioForMac-8.6.0.3771.dmg

Thanks, I was unaware of the incompatibility. I'll go with the old extension for now.

@nosami I switched to the preview channel, but seems that VsVim still isn't activated. I see that the current preview version is 8.6, but you mentioned that

This is slated to change in VSMac 8.7

So it means that for now the only solution is to use XSVim, right?

Uh, I just took a look again and it seems that the version I got from the Preview channel is "8.6 build 3437", but the link you provided is 8.6.0.3771. I'll try it first.

Confirmed that it works with .fs files in version 8.6.0.3771. Still doesn't work with file types such as .config (not sure if they will be supported soon). Thanks for the solution.

Still doesn't work with file types such as .config (not sure if they will be supported soon)

The plan is for all file types to be using the new editor in VSMac 8.7

@x-ji It is possible to have both Vim extensions (VSVim + XSVim) installed if you need .config to work

Sure. I tried to use version 8.6.0.3771 but unfortunately it crashed constantly for me. Guess I'll stick to the normal version for now and use both plugins together until the release of version 8.7

@x-ji Would it be possible to send me the logs? Go to Help -> Open Log Directory. Sounds like something that needs investigating. Thanks!

@nosami Thanks a lot for the quick reply! I'd much prefer to use the new F# editor, if possible. I just uninstalled everything with the two uninstallation scripts, installed the stable version, and replaced the app with version 3771, and was able to reproduce the crash whenever I try to click anywhere in a (.fs) file. The following are the logs:

@x-ji thanks! looks like there is enough information here to diagnose this issue.

@x-ji It _appears_ that this crash is caused by an invalid value for the caret blink timer duration. Is it possible that you have customized this at the OS level?

You can read the blink timer values with these commands

defaults read -g NSTextInsertionPointBlinkPeriodOn
defaults read -g NSTextInsertionPointBlinkPeriodOff

I can reproduce your crash if I run this command

 defaults write -g NSTextInsertionPointBlinkPeriodOn -float 100000000000

It seems that the maximum value is 4294967294. You can reset the blink timer to the defaults by running the following 2 commands

defaults delete -g NSTextInsertionPointBlinkPeriodOn
defaults delete -g NSTextInsertionPointBlinkPeriodOff

Haha that's why! I just wanted to disable VsVim's cursor from blinking. Seems that it only follows the system cursor blinking rate, so I found this answer, which set it to a ridiculously large value...... Thanks a lot for digging into it and helping out so promptly. 馃憤

@x-ji No problem. There's a ticket to add validation to this setting in VSMac, so it should be fixed there soon too :)

That's odd. I have 8.6 build 4516, but .fs files not working with VsVim 馃し

Maybe they removed new editor in new preview versions?

Maybe they removed new editor in new preview versions?

@idchlife 8.6.3771 is a custom build of 8.6 preview 1 with the new F# editor preview added on top of that. The new F# editor isn't officially released yet.

@nosami thanks! Installed manually Vim plugin from your comment https://github.com/VsVim/VsVim/issues/2809#issuecomment-605670797

and it works wonderfully! Thanks

Latest comment by @nosami from #2833:

F# is using the same editor as C# in VSMac 8.8 (Preview channel) and hence is working.
