Commands and config

Every number on the other pages is a config value, and all of them can be changed in place. The commands belong to Expanded Library, not to this mod: the mod id is the section name, so tuning this mod is always /exmod config smex ....

The commands

command	what it does
/exmod config smex	lists every key and its current value
/exmod config smex <key>	reads one key
/exmod config smex <key> <value>	sets one key and writes it to disk. Applies live
/exmod recipes smex	reads the recipe cost level
/exmod recipes smex <normal or cheap>	sets it. Applies on the next world reload
/exmod molds <plate, ingot, rod or all>	reports whether those molds are available
/exmod molds <plate, ingot, rod or all> <on or off>	switches them. Placed molds stop casting at once; the clay-forming recipe and the in-game handbook entry change on the next world reload
.exmod measure <metric or imperial>	a per-player display choice from Pipes and Power Expanded: litres, atm and C, or gallons, psi and F. It changes the panels, never the simulation
.exmod network hi and .exmod network unhi	Expanded Library's per-network block highlight, which is the fastest way to see what a pipe or canal run is actually connected to

The server commands need the controlserver privilege. The two that start with a dot are client side and need nothing.

Older in-game text names /exmod steel <level> for the recipe level; that command does not exist. Use /exmod recipes smex <level>.

The files

ModConfig/smex_values.json holds the values below. The machines re-read it every tick, so a /exmod config change reaches a furnace that is already running. A saved value that is not a number, or is negative, resets to its default on load. An older file called smex.json is migrated to this name once.

ModConfig/smex_recipes.json holds the recipe cost catalogue: which grid recipes and which right-click construction the level applies to, with a normal profile filled in from the recipes as shipped and a cheap profile at half cost. Edit the per-recipe numbers there; the command only picks which profile is live, and the change lands on the next world reload.

Upgrading the mod can reset individual keys. Each release that rebalances something lists the keys it pushes out, and only those are reset; the rest of your tuning is kept. 0.9.7 reset most of the furnace and converter numbers at once, because a saved config from before it left a furnace that could not reach its own melting point.

Molds and recipes

key	default	sets
EnablePlateMold	true	whether the plate mold exists
EnableIngotMold	true	whether the double ingot mold exists
EnableRodMold	true	whether the quad rod mold exists
RecipeLevel	normal	the live profile in smex_recipes.json

smex_recipes.json

The catalogue names what the level applies to, not what it costs: the right-click construction of the converter vessel, and the grid recipes of the tuyere, the furnace door, the furnace tap, the converter's intake, control and transmission, the cowper stove intake, the heat sink, the air blower, the smoke stack intake, both hoppers, the molten barrel, every molten canal piece, and the three slag paths. Each entry carries a normal profile read from the shipped recipe and a cheap profile at half of it, and both are yours to edit.

Reading a value back

If a change through /exmod config does not seem to show, read the value back with the same command: it prints what the server actually holds. RccBrokenDropsRatio was reset to 1.0 for everyone in 0.9.6, so on a current install breaking the converter returns all of its construction materials whatever the file says.
