A small free .Net and JS library (with demo UI, command-line bulk formatter, SSMS/VS add-in, notepad++ plugin, winmerge plugin, and demo webpage) for reformatting and coloring T-SQL code to the user's preferences.
If you'd like some sort of confidence that I'll actually accept a pull request, please push me on getting a contributor agreement together. The gist of the thing would be "Tao gets to use your contributions if he chooses to do something with the project, eg redistribute under a commercial license". Not that I expect that to ever happen (nor that the project is "good"/valuable enough to warrant this), but as a general matter of principle I'd like this project that I've spent so much time on to be something I can keep using even under a different license. (note: I could never rescind the existing license for the existing codebase; the AGPL intentionally ensures this; any more-restrictive license could only ever apply to new code, and/or to a separate packaging/release of the code).
