BazelCon 2024

Actually Portable Executables (APE) is a format of executable that can be ran on Windows, Linux, MacOS, BSDs operating systems from a single binary. A binary can be "fat" to contain both the x86_64 and aarch64 machine code to enable execution on multple CPUs from the same single binary. The `@ape` Bazel module provides the necessary wrappers and launchers to provide common POSIX tooling across all operating systems and CPUs such as `cp`, `mv`, `sed`, `awk` and `curl`. This talk will provide usage information of the `@ape` tools to enable an ecosystem of hermetic tooling for Bazel rulesets that require zero system setup to be used other than a working Bazel installation.

The talk will be split into a few sections:

- An introduction to the Bazel module, it's usage and benefits
- A high level overview into the APE format, Cosmopolitan C library and superconfigure to provide attendees relevant information to understand what the module is providing
- A brief introduction to the ecosystem of hermetic rulesets that expose rules around the APE hermetic binaries, such as `rules_curl`, `rules_gzip`, etc.
