Changelog

Version: 0.1.5
Date: 2026-10-23
  Changes:
    - Updated for Factorio 2.1. Recipes now list several crafting categories (2.1 removed the merged ones like chemistry-or-cryogenics), so machine choice looks across all of them; fuel uses 2.1's fuel_categories.
  Bugfixes:
    - With 2.1's multi-category recipes, a faster machine you haven't researched yet (e.g. the electromagnetic plant for circuits) no longer outbids the buildable assembler.

Version: 0.1.4
Date: 2026-10-20
  Features:
    - Mining fields: asking for an ore (iron, copper, stone, coal) builds a drill-field blueprint sized to the rate instead of a factory. A square-ish block of electric drills (big mining drills once unlocked) with poles and a collector belt that leaves as one full belt per band; higher rates add bands, one output belt each. Mining productivity research counts. Place it over the ore patch.
    - Segments: build the factory as N identical tiles instead of one block. The blueprint holds one segment making its share of the rate; place it N times. Much easier to fit around cliffs and existing base.
    - Debug button: writes the plan (surface, settings, chosen recipes, routing report, blueprint string) to script-output/autoprint-debug.txt for bug reports.
  Bugfixes:
    - Burner machines no longer plan to burn biter eggs: fuel is chosen by safety and availability (no hatching, no spoiling, mined fuels like coal first) instead of alphabetically. A steel-furnace iron plate plan used to grow captive spawners, bioflux, fish breeding and ice melting.
    - Items mined on your surface (coal, stone, ores) are supplied as raw inputs even when a recipe exists, instead of e.g. building coal from coal synthesis. Pick the recipe explicitly to build it anyway.
    - Recipe chains that need their own product further down (carbon from coal, coal from carbon) no longer make the solve diverge.
    - A planner window left open in a save is rebuilt after a mod update, so new buttons appear.

Version: 0.1.3
Date: 2026-07-24
  Changes:
    - Thumbnail is now a screenshot of the planner GUI.

Version: 0.1.2
Date: 2026-07-24
  Changes:
    - Mod portal thumbnail.

Version: 0.1.1
Date: 2026-07-24
  Changes:
    - Clearer, plain-language mod description.

Version: 0.1.0
Date: 2026-07-24
  Features:
    - Planner GUI on a toolbar shortcut: declare products and rates, pick belt/inserter tiers, override recipes or machines per item, mark items external, control surplus provisioning.
    - Rate solver: cyclic recipe graphs (asteroid reprocessing), byproduct banking, built-in machine productivity, surface conditions, tech-gated recipes and machines, burner fuel demands.
    - Blueprint synthesis on a hidden lab surface: the finished factory lands in your cursor as a blueprint; supply chests and pipes mark every raw input to replace with your own logistics.
    - Layout: deepest-first row blocks with up to two input belts plus a side spur per row, catalyst re-pickup loops, self-priming seeder machines, spoilage buffer chests.
    - Belt autorouter: A* with undergrounds, splitter branches for multi-consumer flows, merges for multi-row producers, parallel trunks for over-belt flows, lane-aware joins, multi-pass rip-up and reroute.
    - Fluids: pipe headers feed ingredient fluids, fluid products leave on export mains with per-machine risers or drops, and a dedicated pipe autorouter connects producer mains to consumer supply points (underground-heavy, contact-safe). Unwanted fluid byproducts are voided so machines never jam.
    - Space platforms: mixed asteroid-chunk sushi loop with a filtered sorter at the factory edge, surface-wide power grid support, gravity-aware machine and recipe filtering.
    - Gleba: filtered spoilage taps at belt ends drain into exit columns toward one hookup point; items that spoil into hazards leave spoiled-first; nutrient fuel spurs for burner machines.
    - Power: pole grids along routing channels, post-route pruning of poles that serve nothing.
    - Editor Extensions (optional): infinity chest/loader/pipe supply and output voiders turn every blueprint into a self-contained sandbox test bench.
