3. Libraries bundled within libghostty
================================================================

libghostty (section 1) statically links additional third-party libraries it
vendors itself; their object code ships inside GhosttyKit.xcframework. By SPDX

  - Nerd Fonts codepoint tables (OFL-1.1 for fonts / MIT for code) —
    https://github.com/ryanoasis/nerd-fonts

libghostty also statically links the following Zig-language libraries declared
in `vendor/ghostty/build.zig.zon`:

  - libxev        (MIT)                — https://github.com/mitchellh/libxev
  - uucode        (MIT)                — https://github.com/jacobsandlund/uucode
  - vaxis         (MIT)                — https://github.com/rockorager/libvaxis
  - z2d           (MPL-2.0)            — https://github.com/vancluever/z2d
  - zf            (MIT)                — https://github.com/natecraddock/zf
  - zig-objc      (MIT)                — https://github.com/mitchellh/zig-objc

z2d is MPL-2.0; per §3.2(a) the source for the covered files is freely
available at the upstream URL above.

uucode in turn bundles Bjoern Höhrmann's UTF-8 decoder and Unicode Character
Database data; see the `licenses/` directory in the uucode upstream for the
full texts.

These are vendored and licensed by their respective authors; see
https://github.com/ghostty-org/ghostty and each upstream above for the full
texts.

For the LGPL-2.1 libintl (statically linked into GhosttyKit.xcframework), this
satisfies LGPL-2.1 §6(a): the complete corresponding source is published at
https://github.com/nek0der/limpid (which pins https://github.com/nek0der/ghostty
branch `limpid` as a submodule under `vendor/ghostty`); `make ghostty` invokes
`scripts/build-ghostty.sh` and is the entry point that produces the linker
input `GhosttyKit.xcframework`, which can be relinked against a modified
libintl object set. As a §6(b) fallback, the libintl object files are also
available on written request via GitHub Discussions
(https://github.com/nek0der/limpid/discussions); this offer is valid for at
least three years from the date the corresponding Limpid build was distributed.


================================================================
4. Bundled scripts (shipped under the app's Resources/)
================================================================

Shell-integration scripts under Resources/ghostty/shell-integration/ are
sourced into the user's shell at runtime (data files, not linked into the
binary):

  - zsh/ghostty-integration, zsh/.zshenv, bash/ghostty.bash — adapted from
    Kitty's shell integration. Kitty is licensed under the GNU General Public
    License v3.0 (GPL-3.0); these files remain GPL-3.0. They are redistributed
    as separate, unlinked data files (mere aggregation), so they do not affect
    the MIT license of Limpid's own code or the libghostty binary. Full text:
    https://www.gnu.org/licenses/gpl-3.0.html — https://github.com/kovidgoyal/kitty

  - bash/bash-preexec.sh — bash-preexec, MIT License, Copyright (c) Ryan Caloras
    and contributors. https://github.com/rcaloras/bash-preexec

  - elvish/lib/ghostty-integration.elv,
    fish/vendor_conf.d/ghostty-shell-integration.fish,
    nushell/vendor/autoload/ghostty.nu — original ghostty shell integration
    (not Kitty-derived); distributed under Section 1's MIT license.

Notes
================================================================

This file covers software in the distributed application; build-time-only
toolchains (Zig, Xcode, xcodegen, etc.) are not included. libghostty is built
from our fork https://github.com/nek0der/ghostty (branch `limpid`); all changes
there remain under ghostty's MIT license.
