Incorrect indentation when passing a hashtable as a function argument

[BalassaMarton]

Prerequisites

• I have written a descriptive issue title.
• I have searched all open and closed issues to ensure it has not already been reported.
• I have read the troubleshooting guide.
• I am sure this issue is with the extension itself and does not reproduce in a standalone PowerShell instance.
• I have verified that I am using the latest version of Visual Studio Code and the PowerShell extension.
• If this is a security issue, I have read the security issue reporting guidance.

Summary

Formatting multi-line function calls with hashtable parameters produces incorrect indentation of the function call.

Example script:

function Dummy($ParameterObject) {

}

Dummy `
    -ParameterObject @{
        Property = "value"
    }

After formatting, the script looks like this:

function Dummy($ParameterObject) {

}

Dummy `
    -ParameterObject @{
    Property = "value"
}

Notice how the indentation of the function call is off after the -ParameterObject argument.

Likely an issue in scriptanalyzer, we can see if we can reproduce and an issue would need to be opened there.

As a workaround, have you considered using splatting syntax rather than backticks?

function Dummy($ParameterObject) { $ParameterObject.Property }

$dummyParam = @{
  ParameterObject = @{
    Property = 'value'
  }
}

Dummy @dummyParam

That was just an example minimal repro case. In reality I'm calling Azure PowerShell functions having all sorts of parameters.

Márton Balassa (@BalassaMarton) even in that case I would strongly recommend splatting as you can have conditional parameters, and overall make the invocation much more structured than using backticks with parameters.

Looks to me like the issue is at the PSScriptAnalyzer level, as shown here:

gmo psscriptanalyzer

ModuleType Version    PreRelease Name                                ExportedCommands
---------- -------    ---------- ----                                ----------------
Script     1.22.0                psscriptanalyzer                    {Get-ScriptAnalyzerRule, Invoke-Formatter, Invoke…

So you will need to open the issue in scriptanalyzer and, when fixed and version released, will work its way to this repo to be fixed (you could also install an early release of psscriptanalyzer and the extension can use that)

EDIT: Sorry I initially misread the scriptanalyzer result
EDIT2: Nope, I did in fact read it correctly.
