Powershell build - compiling SASS

Question

I'm hoping to start using SASS in a Visual Studio 2010 project using Web Workbench - but the issue of version control through TFS has me stumped. To avoid overriding someone else's changes I understand that the outputted CSS should be excluded from source control, and that the SCSS should be compiled to CSS server side during the build process. Currently we use a Powershell script for the build, but I can't seem to find any information on how to incorporate SCSS compilation in Powershell. Is there any decent documentation out there on this process?

Answer 1

I think my lack of experience with Powershell/build scripts in general had me overthinking this. I took the following steps:

1) Installed Ruby for Windows from here: https://www.ruby-lang.org/en/documentation/installation/

2) Open Command Prompt -> entered gem install ruby

3) Opened PowerGUI Script Editor (already installed, but can be downloaded here: http://software.dell.com/products/powergui-freeware/)

4) Created a function to execute the following: sass -t compressed "path\sassInput.scss" "path\sassOutput.css"

And presto. I do want to have a way of doing this for each .scss file in the directory that is not a partial, but this is enough to get me started for now.

UPDATE: This is what I ended up with for a Powershell script: (note $dirpath is set to my project's root directory elsewhere)

$stylesheetPath = $dirpath + "App_Themes\"
$files = Get-ChildItem $stylesheetPath -Filter *.scss 
for ($i=0; $i -lt $files.Count; $i++) {
    $file = $files[$i]
    $fileName = $file.BaseName
    $filePath = $file.FullName
    if (-not $fileName.StartsWith("_")) {
        $newFilePath =  "$stylesheetPath$fileName.css"
        sass -t compressed $filePath $newFilePath
    }
}
