What is "zlib"?

A massively spiffy yet delicately unobtrusive compression library.

How to use this package

Quick install

Installs the package into the current environment for this session. Use --build or --runtime to persist it as a build-time or runtime dependency.

min add zlib

Declare as a task dependency in minimal.toml

Listing the package under tasks.<name>.packages makes it available inside that task’s sandbox.

[tasks.dev]
packages = ["zlib"]

Build-time vs runtime

Choose build-time for tools needed during compilation, runtime for dynamic libraries loaded at runtime.

min add --build zlib
min add --runtime zlib
