Allow explicitly specified named parameter to supersede the same one from hashtable splatting.
The work is done in parameter binder, so that parameters can be resolved to cover a parameter's official name, alias name, and unambiguous partial prefix name.
The changes covers covers Hashtable splatting in 3 scenarios:
- Cmdlet or advanced script invocation;
- Simple function invocation;
- ScriptBlock.GetPowerShell(...), where the script block contains command invocation only and uses Hashtable splatting.
Some code refactoring is done to ParameterBinderController to avoid redundant code being duplicated in CmdletParameterBinderController and ScriptParameterBinderController.
Based on standard practices, we need to have a copyright and license notice at the top of each source file. Removed existing copyrights and updated/added copyright notices for .h, .cpp, .cs, .ps1, and .psm1 files.
Updated module manifests for consistency to have Author = "PowerShell" and Company = "Microsoft Corporation". Removed multiple line breaks.
Separate PR coming to update contribution document for new source files: #6140
Manually reviewed each change.
Fix#6073
When calling powershell from powershell (called the minishell for historical reasons), the arguments are passed as a base64 encoded string.
The native command parameter binder was trying to match up the ast to the argument value, which in this case, doesn't make sense.
The fix is to ignore the ast during parameter binding for this case of calling powershell from powershell.
Fix#5733
Previously we used IScriptPosition for context (e.g. error reporting)
during parameter binding, but in some cases we want more information, so
we'll use the Ast instead.
This change just adds the Ast, it doesn't make explicit use of it.
I (Jason Shirk) ran https://github.com/dotnet/codeformatter with the default rules, basically:
codeformatter /nocopyright "/c:DEBUG,UNIX,CORECLR" @files.rsp
This caused a few problems building, which were fixed up manually.
Notable changes:
`this.` is removed unless needed to disambiguate.
private instance fields are renamed to have a `_` prefix.
private static fields are renamed to have a `s_` prefix.
I left some projects alone (like PackageManagement) and also left some generated code alone.
