Json2dir: A JSON-to-directory converter, a fast alternative to home-manager

TL;DR:

file.json:

Here, four files will be added to the current directory: file, dir, symlink, and script.

Using json2dir as a home-manager alternative.

• Objects represent directories.
• Strings represent contents of files.
• Arrays are used to represent symlinks and executable files.
• Arrays of the form ["link", target] represent symlinks, second element representing the target of the symlink.
• Arrays of the form ["script", content] represent executable files, second representing the content of the script.

Regular JSON constraints apply. In particular, the input must be UTF-8. Currently, there's no way to represent files containing non-UTF-8 content.

When using this utility to create files for other users, care must be taken in order to prevent TOCTOU (time of check, time of use) attacks (e.g. with symlinks).

flake.nix contains a Nix package for json2dir.

To build the project, run cargo build or nix build. If you're using rustup, rust-toolchain.toml is provided.

Useful scripts may be found in the scripts folder.

A Nix cache is available at https://json2dir.cachix.org.
