`extractbb-lua` =============== A reimplementation of [`extractbb`](https://texdoc.org/serve/extractbb/0), written in Lua. Variants -------- There are two variants of `extractbb-lua`: - **`wrapper`**: A wrapper script around the original `xdvipdmfx`-based `extractbb` that is used to fix a security vulernability in `xdvipdfmx`. - **`scratch`**: A standalone implementation of `extractbb`, written in Lua from scratch, with no dependencies on `xdvipdfmx`. Currently, the script `extractbb` defaults to the `wrapper` variant, but you can manually select any specific variant by setting the `TEXLIVE_EXTRACTBB` environment variable to either `wrapper` or `scratch`. > [!WARNING] > The `scratch` variant is still in development and may be buggy or > insecure. ### Secret Developer Options If you set `TEXLIVE_EXTRACTBB` to the full path of an executable, it will run that directly. And if you set `TEXLIVE_EXTRACTBB_UNSAFE=unsafe`, then it will ignore some of the security checks.
