Hacky syntax highlighting in git diff

Normally git diff would color additions green and deletions red. This is cool, but it would be even cooler if it adds syntax highlighting to those lines. This is a git pager that does so.

It parses the diff output and picks up the SHAs of files with additions and deletions. It uses [CodeRay][coderay] to highlight each file and then it extracts the lines that are shown in the diff. It then uses [term/ansicolor][color] to make a gradient from the CodeRay color and the diff color (red for deletion, green for addition) and uses it to replace the original.

I tried using rugged instead of shelling out to git show – it was faster overall, but it did incur a noticeable start up time.

Check out the image below for a demo.

# A sneaky wrapper around Rubocop that allows you to run it only against

# on git to figure out which files to check.

# Here are some options you can pass in addition to the ones in rubocop:

Personal Dashboard

I'm looking for someone to collaborate with on a (hopefully) small application.

Over the time I've found that I want to track various things that happen in my life in order to (1) improve productivity, (2) keep up to a schedule I picked or (3) just have an idea what is going on. For me this includes body weight, amount of exercise, time spent in various activities (coding, reading, watching TV), Pomodori completed and whatnot. This is reminiscent of the QuantifiedSelf movement.

The best way I see this is to have a "Personal Dashboard" where I can have all the numbers, charts and reminders I need. I envision it highly customizable – new things you want to keep track of pop up all the time and there should be a nice way to fit them in (like say, you started taking vitamins). Although there are a number of applications that can accomplish this (Lift, MyFitnessPal/FitDay, various Pomodoro timers, etc.), I want it simpler and I want it in one place. Furthermore, I enjoy customizing my habi
