powershell/PSAvoidUsingPositionalParameters is a PSScriptAnalyzer diagnostic emitted by tally for PowerShell snippets embedded in Dockerfiles.
tally disables this rule by default for Dockerfile
RUN snippets because there is no
downstream pipeline or caller in a one-shot container build, so the script-reusability
concerns this rule targets do not apply. Re-enable it with
include = ["powershell/PSAvoidUsingPositionalParameters"] or by setting
rules.powershell.PSAvoidUsingPositionalParameters.severity = "warning" in .tally.toml.Description
Using positional parameters reduces the readability of code and can introduce errors. It is possible that a future version of the cmdlet could change in a way that would break existing scripts if calls to the cmdlet rely on the position of the parameters. For simple cmdlets with only a few positional parameters, the risk is much smaller. To prevent this rule from being too noisy, this rule gets only triggered when there are 3 or more parameters supplied. A simple example where the risk of using positional parameters is negligible, isTest-Path $Path.
