Powerful and customizable text editor with support for a huge list of programming languages and developed as open source. Making multiple changes at once, swapping pieces of code, and a lot more is made trivial with TextMate’s easy way to add multiple insertion points. Select what you want to search, what you want to search for, and TextMate will present the results in a way that makes it easy to jump between matches, extract matched text, or preview desired replacements. See what files have changes in the file browser view, what lines have changes in the editor view, bring up a diff of the current file’s changes, commit a subset, TextMate supports it all for all the major version control systems. One file mixing languages? Projects using different build systems? Third party code with different formatting preferences? TextMate can handle it all by associating detailed scope selectors with key shortcuts, settings, etc.

Shimmer is a lightweight Objective-C library by Facebook that adds an elegant, animated shimmering effect to views—used as a subtle loading indicator, such as in the Paper app. There's also an example project. In the example, you can swipe horizontally and vertically to try various shimmering parameters, or tap to start or stop shimmering. (To build the example locally, you'll need to open FBShimmering.xcworkpace rather than the .xcodeproj.) Shimmer uses the -[CALayer mask] property to enable shimmering, similar to what's described in John Harper's 2009 WWDC talk (unfortunately no longer online). Shimmer uses CoreAnimation's timing features to smoothly transition "on-beat" when starting and stopping the shimmer.

Agar provides a base GUI framework and a standard set of widgets from which graphical applications can be built which run natively under X11, Windows, MacOS, SDL and others. It takes advantage of texture and GPU acceleration wherever available. Agar can also attach to an existing framebuffer, SDL or OpenGL context and operate as a self-contained window-manager. It includes a standard library of general-purpose widgets, and is also designed to be extended externally. New widgets can be implemented as part of an application or library. Complex user interface elements can be realized often in few lines of code. Agar is also extensible at the low-level. The low-level API is documented such that modular drivers can be written which enable Agar applications to work seamlessly under many platforms graphics systems without any change at the application level.
