I got tired of having to hand-copy file paths into the InnoSetup script for PainlessSVN. I'm specifically referring to the Subversion server files. There's something like 278 files, that are in nested folders. I had just finished pasting in all the paths for Subversion 1.6.13, when 1.6.15 was released and I was seriously dreading repeating this whole excersise again.
I needed something that would recurse through both files and folders. It's easy doing one or the other, but not both at the same time (at least for me). I spent about 3 hours last night working on this. The good thing about this code is that I needed something similar for the new DeleteDevCrumbs utility that I'm polishing for release.
As it currently stands, this code will create a list of files from the directory that is passed in through a command-line argument, scan the child directories, and create a text file for you. The file will contain a ready made list that can be pasted right in the [Files] section of an InnoSetup script.
Here's a console app with this code:
using System.Collections.Generic;
using System.IO;
namespace ScanFilesTest
{
class Program
{
private static List<string> _tree = new List<string>();
static void Main(string[] args)
{
string rootDirectory = args[0];
var rootInfo = new DirectoryInfo(rootDirectory);
if (!rootInfo.Exists)
{
throw new DirectoryNotFoundException(string.Format("{0} does not exist!", rootInfo.FullName));
}
FileInfo[] files = rootInfo.GetFiles();
if (files.Length > 0)
{
ScanFolders(files);
}
else
{
DirectoryInfo[] folders = rootInfo.GetDirectories();
ScanFolders(folders);
}
TextWriter subversionList = new StreamWriter("D:\\subversionfilelist.txt");
foreach (var file in _tree)
{
var currInfo = new FileInfo(file);
string currDir = currInfo.FullName.Replace(rootDirectory, string.Empty);
subversionList.WriteLine(string.Format("Source: {0}; DestDir: {{pf}}\\Subversion{1}; Components: Subversion", file, currDir));
subversionList.Flush();
}
subversionList.Close();
}
private static void ScanFolders(FileInfo[] files)
{
foreach (var file in files)
{
if (file != null && !string.IsNullOrEmpty(file.FullName))
{
_tree.Add(file.FullName);
}
}
if (files.Length > 0)
{
string root = files[0].DirectoryName;
var rootInfo = new DirectoryInfo(root);
DirectoryInfo[] folders = rootInfo.GetDirectories();
if (folders.Length > 0)
{
ScanFolders(folders);
}
}
}
private static void ScanFolders(IEnumerable<DirectoryInfo> folders)
{
foreach (var folder in folders)
{
if (folder.GetFiles().Length > 0)
{
ScanFolders(folder.GetFiles());
}
else
{
if (folder.GetDirectories().Length > 0)
{
ScanFolders(folder.GetDirectories());
}
else
{
if (folder != null && !string.IsNullOrEmpty(folder.FullName))
{
_tree.Add(folder.FullName);
}
}
}
}
}
}
}
