Regexo
What it is
Regexo is a free desktop application for developers who create and test regular expressions. It uses the Java Regular Expression language, which the project wiki describes as compatible with almost all regular-expression types. Matching text is highlighted on screen, and entered expressions can replace matching text. Users can save, reopen, and modify expressions, with records kept in a file database. The documented interface includes About, Workspace, Toolbar, Open, Save, and Manage screens. Regexo is built with Java Swing and can run on an operating system providing the Java 6 runtime environment. SourceForge identifies Linux, macOS, and Windows among tested systems, and lists Java as the programming language with JDBC as the database environment. The project is marked Beta and lists GNU General Public License with Classpath exception and Public Domain under License. Its files page lists a 1.6 MB download named Regexo New Version, last modified April 12, 2013.
