ConvertTo-SplatExpression: Cannot find type for custom attribute 'EditorCommand'

[ArtisanByteCrafter]

Working with the newest Powershell Preview extension (tested on v2019.11.0), ConvertTo-SplatExpression fails with the following error. Non-preview powershell extension works as intended.

I've made some changes to the v0.5.0 branch to accommodate the new PowerShellEditorServices architecture. That version is a complete overhaul of the module and isn't where I want it to be for release yet, but it's currently functional and should serve as a drop in replacement.

You can grab a daily here
Edit 2020/02/08: Updated for PowerShellEditorServices 2.0.0-preview.8
Edit 2020/02/22: Updated for PowerShellEditorServices 2.0.0-preview.9

There's a few new editor commands in there, some fixes to old ones, and a lot more configuration options. There's also a context based refactor system similar to "quick fixes" or "code actions". To use that, put something like this in your keybindings.json:

    {
        "key": "ctrl+.",
        "command": "PowerShell.InvokeRegisteredEditorCommand",
        "args": { "commandName": "Invoke-DocumentRefactor" },
        "when": "editorLangId == 'powershell'",
    },

And then press Ctrl + . on whatever you want to refactor.

There's also configuration options scoped to machine, user, or project levels. To create a new settings file, use New-CommandSuiteSettingsFile with either -Scope Machine (or User) or -Path for project. (@markekraus this includes the splat variable name config)

Daily works great @SeeminglyScience - thank you so much for publishing the link as a temporary workaround!

[kilasuit]

Any chance the v 0.5.0 can be pushed to the Gallery as a prelease?

[SeeminglyScience]

@kilasuit Not yet, PowerShellEditorServices is currently changing too rapidly to steadily release previews atm.

Once PowerShell/PowerShellEditorServices#1183 makes it into a vscode-powershell preview release then I'll get something up.

After today's update to Preview 0.5 stopped working again.

Thanks @PrzemyslawKlys! Yeah, some more big changes. I'll get another build ready this weekend.

Fix for preview 9 here. Also updated the link above.

One error still remains.

[SeeminglyScience]

@PrzemyslawKlys That error isn't coming from ESCS, can you file that on PowerShellEditorServices? Also you can remove Import-EditorCommand from your profile, it's no longer required for this module (and that'll bypass that error).
