HarfBuzz
Open source text shaping engine
HarfBuzz is an open source text-shaping engine with a C API that turns fonts and strings of character codes into a form that is correctly arranged for the corresponding language and writing system. This is essentially the process of text shaping: translating a string of character codes into a properly arranged sequence of glyphs that can be rendered onto a screen or into final output form for inclusion in a document. This shaping depends on a number of factors: the input string, the active font, the script (or writing system) of the string, and the string's language. Various font formats have their own set of standard text-shaping rules. With Harfbuzz, you can properly shape all the major writing systems. HarfBuzz is cross-platform and supports all major software platforms and font formats. -

Highlight ranges in the text view. Search the text using regular expressions. Automatically detects if a file is using spaces or tabs for indentation. Specify line endings (CR, LF, CRLF) to use when inserting a line break. Automatically detect line endings in a text. When judging the performance of Runestone, it is key to build your app in the release configuration. The optimizations applied by the compiler when using the release configuration becomes very apparent when opening large documents. The project should mostly work with Catalyst on the Mac, however, it isn't fully tested and the implementation isn't considered done. The focus is currently on the iPhone and iPad. -

Aztec
A reusable native Android rich text editor component
Aztec (which extends EditText) is a rich-text editor component for writing HTML documents in Android. You can check the minimum Android version supported by looking at the minSdkVersion configuration within build.gradle. There is an optional list type you can enable in the editor. In addition to ordered and unordered lists you can use task list. A task list is an unordered list that shows and saves checkboxes instead of bullets. By default, Aztec allows nested blocks. In certain cases, this doesn't have to be the preferred behavior. There is an option to disable nested blocks. When switched, this editor will always add media and horizontal rules after the currently selected block, not in the middle of it. Aztec now supports placeholders to draw views that are not natively supported by the EditText and Spannable API. The functionality creates a span in the visual editor and draws an Android view over it.
