Certain mods add many recipes that take smaller blocks and output a bigger block. This clutters the recipes list. Case in point: the circular saw from the moreblocks mod.
This patch allows mods to tell the craft guide to not include recipes that contain certain items, by setting the group exclude_from_craft_guide = 1 in the items.
When the craft guide is showing a craft, the output slot is now a button,
which causes the craft guide to show ways in which that output can be
used. This mirrors the way input slots are buttons that show recipes
for the selected ingredient. Usages of an item can be iterated through
in the same way as recipes for the item. This incidentally offers some
ability to retrace one's steps through a crafting chain, without storing
actual history.
Commit 043f608145 made shaped crafting
recipes display in a grid of the recipe's minimum bounding box,
but broke the use of a fixed 1x1 grid shape for cooking recipes.
This commit generalises the dynamic-grid-shape facility, putting the
craft type registration in charge. This restores the correct shape for
cooking recipes.
Also change the logic for dynamic grid sizes for regular shaped and
shapeless crafting. We'd like to always use a grid shape that is
reminiscent of a regular crafting grid, as a visual cue to the crafting
method. But it's also nice to show smaller recipes in a smaller grid.
In the expectation that crafting grids will always be square, show the
recipe in the smallest square grid that will accommodate it.
Where a recipe specifies an ingredient by group, show a typical group
item pictorially, with a label flag to indicate that it's a group rather
than the single item. This is the inverse of the previous arrangement,
which identified the group by label and dipicted groupiness pictorially.
The new arrangement is easier to interpret, and if the labels are ignored
it actually shows a correct input to the crafting grid.
New system of registration of craft types, recording for each a display
description and the appropriate grid shape. Recipes of a registered type
are shown in the correct grid. Recipes of unregistered craft types are
still displayed as before, using the default 3x3 grid.
The crafts_table was being initialised to contain only core-registered
crafts, but this would overwrite any non-core craft types that had
already been registered via unified_inventory.register_craft(). This was
especially likely because the crafts_table initialisation runs on a delay,
following all normal initialisation. Instead, feed the core-registered
crafts into unified_inventory.register_craft().
get_all_craft_recipes() returns the recipes that were registered under the
specified name, so asking about an item's canonical name won't see recipes
registered under an alias, and vice versa. Several mods register recipes
under aliases, so the craft guide was missing that handful of recipes.
To work around it, invert the aliases table and ask explicitly about
each alias.
