# Third-Party Notices
|
||
|
|
|
||
|
|
This crate contains code ported from, or derived from, the open-source
|
||
|
|
projects listed under [Ported source code](#ported-source-code), and its
|
||
|
|
release builds embed prebuilt third-party tool binaries listed under
|
||
|
|
[Bundled tool binaries](#bundled-tool-binaries). The original license terms
|
||
|
|
are reproduced below, as required by those licenses.
|
||
|
|
|
||
|
|
Ported files have been modified from their originals (translated between
|
||
|
|
languages, adapted to this crate's `Tool` trait and runtime, and extended);
|
||
|
|
this file constitutes the prominent notice of those changes required by
|
||
|
|
Apache License 2.0 §4(b).

The tool implementations under `src/implementations/codex/` (`apply_patch`,

[openai/codex](https://github.com/openai/codex) project
|

|
|
(`codex-rs/core/src/tools/handlers/`).

## Bundled tool binaries
|
||
|
|
|
||
|
|
Release builds of this crate embed unmodified, prebuilt binaries of the
|
||
|
|
tools below (see `build.rs`); they are self-extracted to `~/.grok/vendor/`
|
||
|
|
at runtime. Which tools are embedded in a given build depends on what the
|
||
|
|
release pipeline supplies at build time:
|
||
|
|
|
||
|
|
- **ripgrep** is embedded in every release build (downloaded from the
|
||
|
|
official GitHub release, or supplied via `GROK_TOOLS_BUNDLE_RG_PATH`).
|
||
|
|
- **ugrep** and **bfs** are embedded only when the release pipeline supplies
|
||
|
|
static binaries via `GROK_TOOLS_BUNDLE_UGREP_PATH` /
|
||
|
|
`GROK_TOOLS_BUNDLE_BFS_PATH`. When those are unset the tools are not
|
||
|
|
bundled, and the runtime instead resolves them from `~/.grok/vendor/` or
|
||
|
|
`$PATH` if the user has installed them. Their license terms are included
|
||
|
|
below so that any build that does bundle them is covered.
|
||
|
|
|
||
|
|
### ripgrep
|
||
|
|
|
||
|
|
[ripgrep](https://github.com/BurntSushi/ripgrep) is dual-licensed under the
|
||
|
|
MIT License or the Unlicense, at the user's option. We redistribute the
|
||
|
|
official ripgrep release binaries and reproduce the MIT license below.
|
||
|
|
|
||
|
|
The official ripgrep release binaries statically link
|
||
|
|
[PCRE2](https://github.com/PCRE2Project/pcre2) (BSD-3-Clause with the PCRE2
|
||
|
|
exemption for binary library-like packages). Under that exemption, packages
|
||
|
|
that include ripgrep — and do not use PCRE2 independently — are not subject
|
||
|
|
to PCRE2's binary-redistribution notice condition, so no separate PCRE2
|
||
|
|
notice is reproduced here.
