Auxiliary packages for [Go 1.25+](https://github.com/essentialkaos/.github/blob/master/GO-VERSION-SUPPORT.md).

### Platform support

Currently we support Linux and macOS (_except some packages_). All packages have stubs for unsupported platforms (_for autocomplete_).

> [!NOTE]
> Some packages cannot be used on some platforms, such as the `fsutil` package, which cannot be used on Windows because it uses syscalls, or `system` subpackages that require [procfs](https://en.wikipedia.org/wiki/Procfs). But you can still write code on these platforms, because almost all packages have stubs with information about all the constants, variables, and functions available on other platforms. For example, Sublime with [LSP](https://lsp.sublimetext.io) on Windows will show all the information about methods that are only available on the Linux platform. All stub descriptions contain the ❗ symbol at the beginning to indicate unsupported code. Code with stubs can be compiled, but any method call from stubs will cause panic.

> [!TIP]
> If you are using SublimeText 4 (`4075+`), we strongly recommend that you install [extended Go syntax highlighting](https://github.com/essentialkaos/blackhole-theme-sublime/blob/master/fmtc.sublime-syntax) with support for `fmtc` [tags](fmtc).
