# Subspace Library

An [experimental take](https://danakj.github.io/2022/12/31/why-subspace.html)

on a safer, simpler C++ standard library.

Please don't use this library. This is an experiment and we don't yet know where

it will take us. There will be breaking changes without warning, and there is no

stable version.

1. See [BUILD.md](BUILD.md) for instructions on building Subspace and Subdoc

and running their tests.

1. See [USAGE.md](USAGE.md) for instructions on integrating the

Subspace library into your project.

1. See [PRINCIPLES.md](PRINCIPLES.md) for the principles behind design choices in

the Subspace library.

1. See [STYLE.md](STYLE.md) for evolving guidance and best practices for

developers of the Subspace library.

## Subdoc

[Subdoc](subdoc/) is a documentation generator from inline C++ documentation

in the spirit of

[Rustdoc](https://doc.rust-lang.org/rustdoc/what-is-rustdoc.html).

The comments in the Subspace library use markdown syntax with additional Subdoc

attributes, and are designed to be consumed by Subdoc in order to generate an

HTML website.

Subdoc is built on top of Subspace, giving the developers a chance to see the

Subspace library in action and test the ergonomics and features of the library.

**Status:**

Subdoc is still very much a work-in-progress, but it is being used to generate

[Subspace documentation](https://suslib.cc)

on each commit.

## Compiler Support

Subspace is a

[concept-first](https://en.cppreference.com/w/cpp/language/constraints)

library and requires C++20.

Compiler support for C++20 varies, and with active development ongoing, bugs in

their implementations still appear and disappear regularly. When in doubt,

check out which compiler versions are used by the

[CI bots](.github/workflows/ci.yml).

| Compiler   | Version |

|------------|---------|

| **Clang:** | 16 and up |

| **GCC**:   | 13 and up |

| **MSVC**:   | VS2022 17.8.1 (Build 17.8.34316.72) and up |

We attempt to work around bugs when reasonable, to widen compiler version

support. See [compiler_bugs.h](sus/macros/__private/compiler_bugs.h) for

the set of bugs we are aware of and currently work around.
