macSVG is a MIT-licensed open-source macOS app for designing HTML5 SVG 1.1 (Scalable Vector Graphics) art and animation. macSVG can produce dynamic, high-quality graphics and animation for HTML5 web views that work on most major desktop and mobile platforms, including iOS, Android, macOS, Microsoft Windows and Linux. macSVG uses the standard macOS WebKit framework for interactive editing and rendering of SVG documents, in addition to several Cocoa plug-in bundles for editing SVG elements and attributes. Apple’s free Xcode system is required to build the macOS application from the source code. Most of the application source code is written in Objective-C language, but a Swift language target has been added recently for a plug-in editor bundle. To build macSVG.app, open "macSVG.xcworkspace" in Xcode, set the build target to "macSVG Debug", build and run.

FLAnimatedImage is a performant animated GIF engine for iOS. Plays multiple GIFs simultaneously with a playback speed comparable to desktop browsers. Honors variable frame delays. Behaves gracefully under memory pressure. Eliminates delays or blocking during the first playback loop. Interprets the frame delays of fast GIFs the same way modern browsers do. It's a well-tested component that powers all GIFs in Flipboard. FLAnimatedImage is a well-encapsulated drop-in component. Simply replace your UIImageView instances with instances of FLAnimatedImageView to get animated GIF support. There is no central cache or state to manage. It's flexible to integrate in your custom image loading stack and backwards compatible to iOS 9. It uses ARC and the Apple frameworks QuartzCore, ImageIO, MobileCoreServices, and CoreGraphics.

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.
