Print out the resulting file. Motivation: Bug reports frequently come with very large test cases. Even ones which look small often import from Phobos. Reducing the test case is the first step in fixing the bug, and it's frequently ~30% of the total time required. Stripping out the unit tests is the most time-consuming and error-prone part of reducing the test case. This should be a good task if you're relatively new to D but would like to do something really useful.Unfortunately, to do that 100% correctly, you need to actually have a working D lexer (and possibly parser). You might be able to get something close enough to work in most cases, but it doesn't take all that much to throw off a basic implementation of this sort of thing if you don't lex/parse it with something which properly understands D.
Well, I made simple lexer for D strings, comments, identifiers and a few other tokens which should be up to that task. It's what I use to parse files and detect dependencies in D for Xcode. Unfortunately, it's written in Objective-C++ (but half of it is plain C)...
