    ANTLR

    ANTLR

    Parser generator to read, process, or translate structured text

    ANTLR (ANother Tool for Language Recognition) is a powerful parser generator for reading, processing, executing, or translating structured text or binary files. It's widely used to build languages, tools, and frameworks. From a grammar, ANTLR generates a parser that can build and walk parse trees. It’s widely used in academia and industry to build all sorts of languages, tools, and frameworks. Twitter search uses ANTLR for query parsing, with over 2 billion queries a day. The languages for Hive and Pig, the data warehouse and analysis systems for Hadoop, both use ANTLR. Lex Machina uses ANTLR for information extraction from legal texts. Oracle uses ANTLR within SQL Developer IDE and their migration tools. NetBeans IDE parses C++ with ANTLR. The HQL language in the Hibernate object-relational mapping framework is built with ANTLR.

    Properties Editor

    Properties Editor

    Save time and effort of converting into Unicode through native2ascii

    Properties Editor can directly edit property files written in Unicode reference characters, eliminating the need to convert to Unicode. In addition to the usual editor functions, it can also be used as an Eclipse plug-in. When you unzip the file, when you unzip the downloaded zip file, a folder called eclipse will be created, and within that there will be folders called features and plugins. Copy this over the actual eclipse folder. Development using the properties file is performed by Java by the setting file of J2EE application, internationalization correspondence with desktop application, etc. being sufficient. However, you have to change the multi-byte character in a file into Unicode with the native2ascii tool of attachment in J2SDK on the character platform un-depending. This editor can directly edit property files written in Unicode reference characters, and saves the time and effort of converting into Unicode through native2ascii.

    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.

Auto generation example for client SDKs, server code, asciidoctor, and HTML documents. OpenAPI Specification (formerly Swagger Specification) is an API description format for REST APIs. An OpenAPI file allows you to describe your entire API. Swagger is a set of open-source tools built around the OpenAPI Specification that can help you design, build, document and consume REST APIs. The ability of APIs to describe their own structure is the root of all awesomeness in OpenAPI. Once written, an OpenAPI specification and Swagger tools can drive your API development further in various ways.
