Dollar sign '$' should be included as part of the variable token

[daviwil]

The dollar sign $ should be included as part of the variable token because editors like VS Code use the syntax tokens to determine what text to select when the user double-clicks in the current file. Currently if the user double-clicks in a variable like $myVar, only the myVar portion will be selected since the $ is treated as a separate symbol.

Originally reported by @deshiknaves with issue PowerShell/vscode-powershell#240.

I would like this fixed as well. Curious if there is any progress/status on it.

Would very much like this too by way of default.

Eventually, ended up with editing the "editor.wordSeparators" setting for PHP only.
As per documentation suggestion.
Using: "Preferences: Configure language specific settings" as the command for selecting PHP.

Are we sure this is what we really want? Some of the guides I have seen regarding scope names suggests that the $ should be scoped as punctuation.definition.variable I tried a test where I renamed this scope to variable.punctuation as this would mean that both the $ and the variable name have the same root scope. Double-clicking in vscode still only highlighted the variable name.

I then tried to apply a meta.variable scope to the whole token ($ as well as the variable name), with the same results.

Checking in ISE this is the exact same behaviour I see there. The name of the variable is highlighted on double-click, not the $.

Yep, you are correct that this is the same behavior as in PowerShell ISE (which is ALSO terrible behavior). I STILL default to using the very old PowerShell GUI Editor because it DOES have the correct behavior of including the $ when double clicking. It's a huge burden on speed to not be able to quickly copy and paste variables including the $

[gravejester]

My only concern is that it won't work even if we scope the $ the same as the variable name. @daviwil do you know for certain that the editor is using the scope names for this? If not, is there any other way we can achieve this? Perhaps as a setting so that people can choose if they want this behavior or not?

[gravejester]

As mentioned above, adding the following to the settings works:

"[powershell]": {
    "editor.wordSeparators": "`~!@#%^&*()-=+[{]}\\|;:'\",.<>/?"
}

[daviwil]

@gravejester hmmm... If this is driven by editor.wordSeparators, then maybe the syntax def has nothing to do with it. Let me see if there's some way I can make this happen via the PS extension.

[daviwil]

Filed an issue with the VS Code team to see if there's a way I can override that setting.

Also just found this issue at the vscode-PowerShell repo where someone also asked for the dollar sign to be colored the same as the variable name.

[gravejester]

Yeah, I have mixed feelings about that. In the grammar I'm much more concerned with the tokens getting "proper" scope names, and leave it up the the different themes how these should be colored. I'd rather not cheat by using the wrong scope names just so that a token can get a particular color in the default theme. Thoughts?

[daviwil]

Sounds fine to me to have accurate tokens. The ISE theme can color the token consistently with the ISE :)
