Using ScriptCS to Solve Simple Scripting Problems

A long time friend Glenn Block has been working on a new bleeding edge project over at Microsoft called ScriptCS. I have heard him mention it a few times, but had not had the chance to check it out.

Scott Hanselman posted about the project today and I decided it was time to give it a look. Go read his blog to get an idea of what you can do with it.

TLDR; ScriptCS is a scripting environment for c# built on Rosyln. Similar to csscript, that I used a couple years while using Wix# to build installers, back but SO MUCH BETTER.

I wanted to give it a go, so I decided to implement the solution from my last post using it.

Here is what I came up with:

using System.IO;
using System.Diagnostics;

var ROOT_DIRECTORY = @"C:\Projects\Released\Tests.Integration";

public string GetLastUpdatedDate(FileInfo file){
	var command = new ProcessStartInfo("git.exe", "log -1 --format=%ci " + file.FullName){
		UseShellExecute = false,
		RedirectStandardOutput = true
	};
	var process = Process.Start(command);
	              process.WaitForExit();
	return process.StandardOutput.ReadToEnd().Trim();
}

public IEnumerable<FileInfo> GetAllFiles(string directory) {
	var directoryfiles = from file in Directory.GetFiles(directory)
			     let fileinfo = new FileInfo(file)
			     select fileinfo;
	
	var subdirectoryfiles = from subdirectory in Directory.GetDirectories(directory)
				let files = GetAllFiles(subdirectory)
				from file in files
				select file;

	return directoryfiles.Union(subdirectoryfiles);

}

var results = from file in GetAllFiles(ROOT_DIRECTORY)
	      where file.FullName.EndsWith(".cs")
	       select string.Format("{0} \t {1}", GetLastUpdatedDate(file), file.FullName);

Array.ForEach(results.ToArray(), Console.WriteLine);

All in all, I am plesantly suprised. This has possibilites.
