## tmux

First and foremost, thank you to **[Nicholas Marriott (nicm)](https://github.com/nicm)**,
the creator of tmux, and to the many
[tmux contributors](https://github.com/tmux/tmux/graphs/contributors).
We are grateful for the work that makes tmux possible.

libtmux is a separate project. Our libraries and supporting tools control a
real tmux server; tmux itself provides the terminal multiplexer. This is the
libtmux website. Visit the [official tmux website](https://github.com/tmux/tmux/wiki)
for the upstream project and its documentation.

See tmux's [COPYING file](https://github.com/tmux/tmux/blob/master/COPYING)
and the copyright and permission notices in its source files for its licensing.

### tmux artwork

The tmux logomark is by Jason Long. The site uses the unmodified
[upstream SVG](https://github.com/tmux/tmux/blob/8f25579c5aef8d93924a20681f394e2a582fd3ad/logo/tmux-logomark.svg)
under its [copyright and permission notice](https://libtmux.org/en/brand/tmux/LICENSE.txt).

## Programming-language artwork

The homepage language selector uses local copies of the following artwork
to identify the selected language. Each source record includes the download
URL, retrieval time, file hash, copyright information and usage terms.
These marks identify their respective languages and do not imply endorsement
of libtmux.

The SVG files are copied unchanged except for Scala, whose empty surrounding
canvas is cropped. Its paths, gradients and colors are preserved, and the
original SVG is retained beside the cropped copy. Rust's supplied SVG includes
its own dark-theme colors.

## Terminal artwork

The tmux CLI selector displays the Windows Terminal artwork by Microsoft
Corporation, licensed under [CC BY-ND 4.0](https://creativecommons.org/licenses/by-nd/4.0/).
The SVG is unmodified. See the [source and provenance](https://libtmux.org/en/brand/tools/terminal/provenance.json)
and [copyright and license](https://libtmux.org/en/brand/tools/terminal/LICENSE.txt).

## Documentation toolchain

libtmux and this site are built with open-source software. The following
tools have their own licences and attribution requirements.

| Tool | Licence | Role |
|---|---|---|
| [Astro](https://astro.build/) | MIT | The site shell |
| [Tailwind CSS](https://tailwindcss.com/) | MIT | Styling |
| [Pagefind](https://pagefind.app/) | MIT | Site-wide search |
| [Expressive Code](https://expressive-code.com/) | MIT | Code blocks |
| [Sphinx](https://www.sphinx-doc.org/) | BSD-2-Clause | Python and C++ reference |
| [Furo](https://github.com/pradyunsg/furo) | MIT | Sphinx theme |
| [Breathe](https://github.com/breathe-doc/breathe) | BSD-3-Clause | Doxygen XML into Sphinx |
| [Doxygen](https://www.doxygen.nl/) | GPL-2.0-only | Parses C++ headers to XML |
| [API Extractor](https://api-extractor.com/) | MIT | TypeScript API model |
| [IBM Plex](https://github.com/IBM/plex) | OFL-1.1 | Typeface |

### A note on Doxygen

Doxygen is licensed GPL-2.0-only. It runs as a build step that reads libtmux's
own headers and emits XML; that XML is rendered by Breathe and Sphinx, and no
Doxygen-generated HTML is published. Running a GPL program over your own input
does not place its licence on the output, and libtmux does not distribute
Doxygen or any modified version of it.

## Reference hosting

The [PyPI blocks logo](https://pypi.org/trademarks/) is a trademark of the
Python Software Foundation and identifies links to the Python Package Index.
Other package-host icons use [Simple Icons](https://simpleicons.org/)
(CC0-1.0). The docs.rs mark is its
[`docsdotrs` icon](https://github.com/simple-icons/simple-icons/blob/16.35.0/icons/docsdotrs.svg),
inlined unchanged. The book beside javadoc.io links is original artwork for
this site: the host publishes no vector logo, and the mark does not imitate
its favicon.

Some ports deep-link to the canonical host their ecosystem already uses,
rather than duplicating it here:

- Rust: [docs.rs](https://docs.rs/libtmux), for each published crate
- Go: [pkg.go.dev](https://pkg.go.dev/github.com/libtmux/libtmux-go/tmux)
- Java, Kotlin and Scala: [javadoc.io](https://javadoc.io/doc/io.github.libtmux/libtmux)
- Swift: the [Swift Package Index](https://swiftpackageindex.com/libtmux/libtmux-swift/documentation/libtmux)
  copy of the DocC reference

Those sites are operated independently of this project and carry their own
terms.
