prototype of PS project language.ps1

### this is preamble (framework code), the user wouldn't type this.

$bindings = @{
  projects = @()
}

function project($projectFilename, $block) {
  function output-type($type) {
    #maybe validate or translate, etc...
    $bindings.outputType = $type
  }

  function framework-version($version) {
    $bindings.frameworkVersion = $version
  }
  
  function project-type($projectType) {
    $mappedType = switch($projectType) {
      mvc2 { 'F85E285D-A4E0-4152-9332-AB1D724D3325' }
      asp.net { '349C5851-65DF-11DA-9384-00065B846F21' }
      csharpwindows { 'FAE04EC0-301F-11D3-BF4B-00C04F79EFBC' }
      default { $null }
    }
    if($mappedType -eq $null) {
      write-host "Warning: project-type code '$projectType' is unknown."
      return
    }
    
    $bindings.projectTypes += $mappedType
  }
  
  function references($block) {
    function assembly($name, $framework = $null, $path = $null, [switch]$specific, [switch]$notSpecific, [switch]$copy, [switch]$nocopy) {
      $bindings.items += @{ 
        name = $name
        framework = $framework
        path = $path
        specific = $specific -or !$notSpecific
        copyLocal = $copy -or !$nocopy 
      }
    }
    
    $references = & { $bindings = @{ defaultPath = $null; items = @() }; & $block; $bindings }
    $bindings.references += $references
  }

  $project = @{ 
    projectTypes = @()
    references = @() 
  }
  $project = & { $bindings = $project; & $block; $bindings }
  $project.projectFilename = $projectFilename
  
  $bindings.projects += $project
}

### this is the part the user would type!!!
project src/WebRole/WebRole.csproj {
  output-type library
  framework-version 4
  project-type mvc2
  project-type asp.net
  project-type csharpwindows
  references {
    assembly System
    assembly System.Core -framework 3.5
    assembly Castle.Core -path packages\Castle.Core.2.5.2\lib\NET35\Castle.Core.dll
    assembly 'Milliman.MGAlfa.Atb2, Version=7.4.118.0, Culture=neutral, processorArchitecture=MSIL' -notSpecific
    assembly 'System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL' -copy
  }
}

### this is what we do afterwards.
# TODO: Actually create the project files
$bindings | Format-Table

The example is plesant to read .... That's nice
