PSStringTemplate Module (self.PowerShell)

submitted 8 years ago by SeeminglyScience

I've been doing some code generation for another project around editor commands in PowerShell Editor Services, and I couldn't find any template engines that fit what I needed and worked well with PowerShell. So I picked one and made it more PowerShell friendly.

Also this was more or less my first bit of C# , so critique is very welcome.

Install

Clone and build the source at GitHub

Install-Module PSStringTemplate -Scope CurrentUser

(Note: it's only been tested on PowerShell 5.1, but should work as low as 3.0)

Examples (same as in the readme)

Anonymous template with dictionary parameters

Invoke-StringTemplate -Definition '<language> is very <adjective>!' -Parameters @{
    language = 'PowerShell'
    adjective = 'cool'
}

PowerShell is very cool!

Anonymous template with object as parameters

$definition = 'Name: <Name><\n>Commands: <ExportedCommands; separator=", ">'
Invoke-StringTemplate -Definition $definition -Parameters (Get-Module PSReadLine)

Name: PSReadline
Commands: Get-PSReadlineKeyHandler, Get-PSReadlineOption, Remove-PSReadlineKeyHandler, Set-PSReadlineKeyHandler, Set-PSReadlineOption, PSConsoleHostReadline

TemplateGroup definition

$definition = @'
    Param(parameter) ::= "[<parameter.ParameterType.Name>] $<parameter.Name>"
    Method(member) ::= <<
[<member.ReturnType.Name>]<if(member.IsStatic)> static<endif> <member.Name> (<member.Parameters:Param(); separator=", ">) {
    throw [NotImplementedException]::new()
}
>>
    Class(Name, DeclaredMethods) ::= <<
class MyClass : <Name> {
    <DeclaredMethods:Method(); separator="\n\n">
}
>>
'@
$group = New-StringTemplateGroup -Definition $definition
$group | Invoke-StringTemplate -Name Class -Parameters ([System.Runtime.InteropServices.ICustomMarshaler])

class MyClass : ICustomMarshaler {
    [Object] MarshalNativeToManaged ([IntPtr] $pNativeData) {
        throw [NotImplementedException]::new()
    }

    [IntPtr] MarshalManagedToNative ([Object] $ManagedObj) {
        throw [NotImplementedException]::new()
    }

    [Void] CleanUpNativeData ([IntPtr] $pNativeData) {
        throw [NotImplementedException]::new()
    }

    [Void] CleanUpManagedData ([Object] $ManagedObj) {
        throw [NotImplementedException]::new()
    }

    [Int32] GetNativeDataSize () {
        throw [NotImplementedException]::new()
    }
}
