v1.3.2 - Custom Delimiters

Added Delimiter Support to Get-MustacheTemplate and ConvertFrom-MustacheTemplate as requested in #2 .

This can be usefull if you want to use a template which already contains mustache-like tags for another templating engine which shall be left untouched.

ConvertFrom-MustacheTemplate -Template 'Hi [[Name]], {{keepThisUntouched}}!' -Values @{Name='Joe'} -DelimiterLeft '[[' -DelimiterRight ']]'

Hi Joe, {{keepThisUntouched}}!

v1.3.1 - Template Caching Support

The new Function Get-MustacheTemplate was added to enable caching of a Mustache Template for multiple runs. (As asked in #1 )
If the values comes from the pipeline, the Template is also implicitly cached upon the first run.

PS> # Generate Test Data
PS> $data = New-Object System.Collections.ArrayList
PS> 1..1000  | %{ $data.Add(@{Num = $_}) | Out-Null }

PS> # Explicit Caching
PS> (Measure-Command { $template = Get-MustacheTemplate -Template 'Current Iteration {{Num}}';  $data | ConvertFrom-MustacheTemplate -Template $template }).TotalMilliseconds
192,4528

PS> # Implicit Caching
PS> (Measure-Command { $data | ConvertFrom-MustacheTemplate -Template  'Current Iteration {{Num}}' }).TotalMilliseconds
191,006

PS> # No Caching / iterating
PS> (Measure-Command { $data | ForEach-Object { ConvertFrom-MustacheTemplate -Template 'Current Iteration {{Num}}' -Values $_  }}).TotalMilliseconds
584,1476

If you have any feedback how this affects complex runs please leave it here. :)

v1.3 - Lambda Support

This release adds "Lambda-Support" to PSMustache along with a few minor performance improvements.
You can simply pass a ScriptBlock as Member of a Hashtable to get the code executed.

The Lambda-Functions can be used in Interpolation-Tags {{MyFunction}} as well as in Sections.

When used in Interpolation Tags, the ScriptBlock is called without any parameters.

PS> ConvertFrom-MustacheTemplate -Template 'Current Time: {{Time}}' -Values @{'time' = { Get-Date }}

Current Time: 05/11/2021 17:00:00

In Sections-Tags the content of the section is passed to the ScriptBlock:

PS> ConvertFrom-MustacheTemplate -Template 'Current Date: {{#Time}}yyyy-MM-dd{{/Time}}' -Values @{'time' = {Get-Date -Format $args[0]}}

Current Date: 2021-05-11

You can grab the content of the section tags via $args[0] (as in the above example) or via params, when defined in the ScriptBlock:

ConvertFrom-MustacheTemplate -Template 'Current Time: {{#Time}}yyyy-MM-dd{{/Time}}' -Values @{'time' = {param($format) Get-Date -Format $format}}

Current Date: 2021-05-11

Hope you enjoy the new feature and find it useful. :-)
