Ninja is a small build system with a focus on speed. It differs from other build systems in two major respects: it is designed to have its input files generated by a higher-level build system, and it is designed to run builds as fast as possible.
In essence, Ninja is meant to replace Make, which is slow when performing incremental (or no-op) builds.[4] This can considerably slow down developers working on large projects, such as Google Chrome which compiles 40,000 input files into a single executable. In fact, Google Chrome is a main user and motivation for Ninja.[5] It's also used to build Android,[6] and is used by most developers working on LLVM.[7]
In contrast to Make, Ninja lacks features such as string manipulation, as Ninja build files are not meant to be written by hand. Instead, a "build generator" should be used to generate Ninja build files. Gyp, CMake, Meson, and gn[8] are popular build management software tools which support creating build files for Ninja.[9]
Example
rule cc
command = gcc -c -o $out $in
description = CC $out
rule link
command = gcc -o $out $in
description = LINK $out
build source1.o: cc source1.c
build source2.o: cc source2.c
build myprogram: link source1.o source2.o
