First thing every software engineer does after leaving Google is rewrite Blaze. Just like every site reliability engineer rewrites borgmon. What I chose to do myself was make Blaze happen using a Makefile config. There's a blog post somewhere where Google talks about why they switched from GNU Make to Blaze c. 2006. if I remember correctly it basically boiled down to not having strict dependency checking. So I thought, why not simply avoid their published mistakes without changing build systems? I learned everything I could about make, discovered that variables are secretly lambdas, and that enabled me to figure out a way to have a static archive package for each folder, which also avoided the need to write a makefile code generator. Then I wrote a simple C program to check incremental elf symbols so the build graph stays sanely formed. It totally got make working like a dream in a way I simply hadn't seen before. https://github.com/jart/cosmopolitan/blob/master/tool/build/...
