I would like to find all file paths that are not filtered by a .gitignore (or any nested .gitignore files within sub-directories) using C#. This is similar to the question here with regard to PHP. I'm wondering if someone knows if this code had already been made available (in C#) somewhere online.
UPDATE: To answer what I want this for, it is so I can run my own little periodic backup of my source files for certain projects (zipping the result), for added peace of mind. The hard part is getting a robust .gitignore parser to get the filtered file paths (and exclude the others), without wanting to become too embroiled in learning that spec if someone else already has done it for me.
It's difficult to make suggestions without knowing exactly what you want to do with the list (use it in a build script, process the files in some way, just view them on a UI, etc.)
I couldn't find one in C#, but this JavaScript gitignore parser doesn't have a lot of code to convert and it exposes both an accepts and a denies method to get a list of included or ignored files. It is fairly well documented, has tests, and the regular expressions it uses would work just as well in C# as they do in JavaScript.
This answer would work from C#, provided you have Git installed on the machine where your C# code is running.
Also note that the Git Source Control Provider plugin for Visual Studio provides the list right in the IDE, along with the ability to check boxes and commit certain files together and a lot of other functionality that is difficult to do on the command line.
NOTE: The Git Source Control Provider is open source (written in C#) and you can view the source here, but it may be much more involved to reverse engineer than the JavaScript project.
