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.
When the current craft guide item has no recipes, show a "no" symbol
instead of an ingredient grid, alongside the "No recipes" message.
When no item is selected in the craft guide, leave the recipe space empty.
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.
Extend the representative-item logic to handle ingredients specified
as the intersection of multiple groups. Also add mangling of item
button content, because comma for a multi-group ingredient is getting
formspec-escaped and then not de-escaped.
Commit 043f608145 broke a couple of things
in the course of its refactoring. This patch restores the "G" flag that
signals group ingredients, the preference for "default:" items as group
representatives (where a representative isn't specifically registered),
and the built-in registration of default:cobble as representative for
group:stone (because it's the most commonly-used item in that group).
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.
Alloy cooking recipes have quantities for the ingredients, which need to
be shown. The buttons on which the ingredients are shown don't natively
support showing an item count, so hack it up with the label facility.
Also, the button names, supporting clicking to see recipes recursively,
need to be based only on the item name part of the ingredient, dropping
the quantity part.
The refill slot was only putting as many items as possible in a
stack, which does nothing for tools. Tools could benefit from repair,
recharging, or other behaviour depending on the type of tool. Change the
default refill behaviour to repair mechanical wear as well as fully
stacking. Because other kinds of refill will require knowledge of the
metadata format, they can't be directly handled here. So add an on_refill
hook, that tool definitions can supply to plug in appropriate behaviour.
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().
When the current search produces no results, give a specific message
rather than "Page 1 of 0". Don't display the "Filter:" label if no
filtering is currently applied.
Keep the current inventory search string when performing inventory
form actions other than searching. This means the player's input is
not lost if the player breaks off from entering it to switch pages,
or if the player absent-mindedly ends text input with <return>.
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.
