GYP (software)
GYP is a build automation tool. GYP was created by Google to generate native IDE project files for building the Chromium web browser and is licensed as open source software using the BSD software license.
The functionality of GYP is similar to the CMake build tool. GYP processes a file that contains a JSON dictionary in order to generate one or more target project make files. The single source.GYP file is generic while the target files are specific to each targeted build tool.
Software projects being built using GYP included the Node.js, WebRTC, and Telegram. Software projects that migrated from GYP to GN included the V8 Javascript engine, Google's Chromium web browser, Dart.
In 2016, the Chromium project replaced GYP with GN, which is 20x faster for their use case.
