    HarfBuzz

    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.

    Draft.js

    Draft.js

    React framework for building text editors

    Draft.js is a framework for building rich text editors in React, powered by an immutable model and abstracting over cross-browser differences. Draft.js allows you to build any type of rich text input, whether you're only looking to support a few inline text styles or building a complex text editor for composing long-form articles. We provide the building blocks to enable the creation of a broad variety of rich text composition experiences, from basic text styles to embedded media. Draft.js fits seamlessly into React applications, abstracting away the details of rendering, selection, and input behavior with a familiar declarative API. The Draft.js model is built with immutable-js, offering an API with functional state updates and aggressively leveraging data persistence for scalable memory usage.

    MaterialEditText

    MaterialEditText

    EditText in Material Design

    AppCompat v21 makes it easy to use Material Design EditText in our apps, but it's so limited. If you've tried that, you know what I mean. So I wrote MaterialEditText, the EditText in Material Design, with more features that Google Material Design Spec has introduced. Base color will be used as bottom line color, text color (reset alpha to 87%) and hint text color (reset alpha to 26%). You can use app:met_baseColor in xml or setBaseColor() in java code. If you haven't set a base color, black will be used. Primary color will be used as the activated bottom line color, highlight floating label color, and singleline ellipsis color. You can use app:met_primaryColor in xml or setPrimaryColor() in java code. If you haven't set a primary color, the base color will be used. Just use com.rengwuxian.materialedittext.MaterialEditText instead of EditText in your layout xml. MaterialEditText has directly inherited EditText, so you don't have to change your java code.
