Xmake is a lightweight cross-platform build tool based on Lua. It uses xmake.lua to maintain project builds. Compared with makefile/CMakeLists.txt, the configuration syntax is more Concise and intuitive, it is very friendly to novices, and you can get started quickly in a short time, allowing users to focus more on actual project development.
After several versions of iterative testing, we officially switched to the Lua5.4 runtime from Luajit in version 2.6.1.
However, this is completely unaware to users, and basically there is no compatibility problem, because xmake encapsulates most of the interfaces, which completely eliminates the compatibility problem between Lua versions.
In terms of build performance, because the performance bottleneck of the build mainly comes from the compiler, the performance loss of Lua itself is completely negligible, and xmake rewrites all lua native io interfaces with c, and optimizes the time-consuming interfaces with c .
Therefore, through comparative tests, whether it is using Lua or Luajit, the time-consuming to build the project is basically the same, and there is no significant difference.
Because Luajit basically does not support some new architectures, such as: riscv, lonngarch, and the author of luajit has basically not maintained it, some new architecture support and stability repair progress is in a stagnant state.
In order to be able to better support more platforms and have obtained faster iterative maintenance, we choose to use Lua will bring many benefits.
