What is a .ninja file?
File Extension Details
A Ninja build file is a configuration file used by the Ninja build system, a small and incredibly fast build tool designed to focus on speed. Unlike more traditional build systems like Make, which are designed to be written by hand, Ninja files are typically generated by higher-level build systems such as CMake, Meson, or GN. The format is intentionally low-level and simple, prioritizing fast parsing and execution over human readability or manual authoring. It uses a declarative syntax to define build rules, variables, and build edges that describe how to transform input files into output files. Because it avoids complex features like string manipulation or conditional logic within the file itself, Ninja can start builds almost instantaneously, even for massive projects with tens of thousands of files. It is widely utilized in major open-source projects including Chromium, LLVM, and the Android Open Source Project. The file serves as a manifest that tells the Ninja executable exactly which commands to run and in what order based on file timestamps and dependency graphs.
