This is outdated now. Compilation does not use the tmp directory anymore.

** Big picture of the Zig caching system. ** This is a big picture of the Zig caching system, mostly motivated for me to understand the necessary bits to solve ziglang/zig#11643. It reflects the status quo of commit fcfeafe99a3ecc694a3475735c81a0d75b6da6d0. The core logic is defined in src/Cache.zig.

zig-cache/h contains the manifest files with varying content.

Idea
1. parsing the AST to have a simplification for faster frequent access
   * create another tree storing what things are active
   * create another tree to store what things reference what other things for deletion strategy
     (idea: no unused variable errors)
2. starting with remove stuff from end of execution to beginning and fixup unused var errors,
   later graph based deletion based on where things are used (!global side effects may not be captured!)
3. rendering the used parts
   * fixups will be likely dirty hacks at first

Why storing accurate editor history requires to separate layout from content.

Let us understand programming as converting strings to another machine-readable or executable output with a program according to a specification (called compiler). Now let the sole layout as graphical positioning be defined by additional white spaces and newlines.

Source code formatting ensures stylistic consistency to improve readability and eases on refactoring and writing code. All formatters that enable custom user data come with an escape hatch for
