Factorio Exporter

A Rust library to export prototype definitions from Factorio.

This is both a library as well as a command line tool to export prototype definitions from Factorio.

See crate page on crates.io

Example invocation

sh $ factorio_exporter --factorio-dir ~/tmp/factorio-full -f json | jq '.recipe_prototypes["iron-plate"]'

Output:

json { "allow_as_intermediate": true, "allow_decomposition": true, "allow_inserter_overload": true, "allow_intermediates": true, "always_show_made_in": false, "always_show_products": false, "category": "smelting", "emissions_multiplier": 1, "enabled": true, "energy": 3.2, "hidden": false, "hidden_from_flow_stats": false, "hidden_from_player_crafting": false, "ingredients": [ { "amount": 1, "name": "iron-ore", "type": "item" } ], "localised_description": "Unknown key: \"recipe-description.iron-plate\"", "localised_name": "Iron plate", "name": "iron-plate", "object_name": "LuaRecipePrototype", "order": "b[iron-plate]", "overload_multiplier": 0, "products": [ { "amount": 1, "name": "iron-plate", "probability": 1, "type": "item" } ], "request_paste_multiplier": 30, "show_amount_in_title": true, "unlock_results": true, "valid": true }

Command line

```sh $ factorio_exporter --help Exports prototypes from Factorio in JSON or YAML format

Usage: factorio_exporter [OPTIONS] [MODS]...

Arguments: [MODS]... Mods to install before exporting the prototypes

Options: --factorio-dir Directory where Factorio is installed. This needs to be the full version. Neither the demo nor the headless version are sufficient. This argument is optional if both of --factorio-api-spec and --factorio-binary are specified

  --factorio-api-spec <FACTORIO_API_SPEC>
      Location of the `runtime-api.json` file. Defaults to `<FACTORIO_DIR>/doc-html/runtime-api.json`

      The spec can be found in the `doc-html` directory of a full Factorio installation, or [online](https://lua-api.factorio.com/latest/runtime-api.json).

  --factorio-binary <FACTORIO_BINARY>
      Location of the factorio binary. Defaults to `<FACTORIO_DIR>/bin/x64/factorio(.exe)`. This can be any Factorio binary (full, headless, demo)

-d, --destination Path where the result should be written. Uses STDOUT if not specified

-f, --format Format of the output

      [default: json]
      [possible values: json, yaml]

-i, --icons Export icon paths

-h, --help Print help information (use -h for a summary)

-V, --version Print version information ```

Library

See factorio_exporter.rs for how to use the crate as a library.

Status

This is still very much in the prototype phase. The output will be incomplete and have bugs. Please try it out anyway and report any issues that you run into!

See the change log for progress.

Design

The goal of the importer is to be as close as possible to the authoritative definition of the prototypes. It tries to achieve that goal by two design decisions:

• The prototypes are exported from a running Factorio instance in the runtime stage. This means that the prototypes are as close as possible to how they are used in the game.

• The list of exported properties is taken from the official definition.

Another consequence of this design is that it allows to export the prototypes of loaded mods.

Platform support

This library is intended to be platform-independent, but it's currently only tested on Linux.

Contributions are welcome! Feel free to send pull requests, but if you want to make large-scale changes it would make sense to discuss them first.
