Enabling Debug Logging

[ollien]

I've struggled to get debug logs to work when working on the extension. I tried doing "Developer: Set Log Level" > "vscode-neovim" > "Trace", but I don't see anything in the output console (with vscode-neovim selected), or the developer console. Is there something else that I'm meant to do?

We should update the codebase to do what you are expecting. But currently the extension log-level is driven by the vscode-neovim.logLevel setting.

This is because vscode LogOutputChannel was only recently implemented: f77256b

Note: there is also an outdated comment here:

vscode-neovim/src/logger.ts

Lines 112 to 118 in 4ccd611

	case LogLevel.debug:
	// XXX: `vscode.LogOutputChannel` loglevel is currently readonly:
	// https://github.com/microsoft/vscode/issues/170450
	// https://github.com/PowerShell/vscode-powershell/issues/4441
	// So debug() drops messages unless the user has increased vscode's log-level.
	// Use info() until vscode adds a way to set the loglevel.
	this.outputChannel.info(fullMsg);

Proposal

We should remove the vscode-neovim.logLevel setting and let Developer: Set Log Level (and the local LogOutputChannel.logLevel field) decide the vscode-neovim log level.

I also believe when the log channel was implemented, there was no way to set the log level in vscode.
