[WSO2Con EU 2017] An Overview of Ballerina Composer
1 like456 views
Ballerina Composer is a tool for graphically and textually editing Ballerina programs, offering features such as a graphical editor, code completion, and integration with language servers. It allows users to create and manage APIs using a combination of graphical and textual syntax. Future developments include enhancing integration with other editors and building a desktop version.
