## API
### Custom recipes
#### Registering a custom crafting type (example)
```Lua
craftguide.register_craft_type("digging", {
description = "Digging",
icon = "default_tool_steelpick.png",
})
```
#### Registering a custom crafting recipe (examples)
2019-02-13 14:24:13 +01:00
```Lua
craftguide.register_craft({
type = "digging",
width = 1,
result = "default:cobble 2",
2019-02-13 14:24:13 +01:00
items = {"default:stone"},
})
```
Recipes can also be registered in a Minecraft-like way:
```Lua
craftguide.register_craft({
grid = {
"X #",
" ## ",
"X#X#",
"X X",
},
key = {
['#'] = "default:wood",
['X'] = "default:glass",
},
result = "default:mese 3",
})
```

### Recipe filters
Recipe filters can be used to filter the recipes shown to players. Progressive
mode is implemented as a recipe filter.
#### `craftguide.add_recipe_filter(name, function(recipes, player))`
Adds a recipe filter with the given name. The filter function should return the
recipes to be displayed, given the available recipes and an `ObjectRef` to the
user. Each recipe is a table of the form returned by
`minetest.get_craft_recipe`.
Example function to hide recipes for items from a mod called "secretstuff":
```lua
craftguide.add_recipe_filter("Hide secretstuff", function(recipes)
local filtered = {}
for _, recipe in ipairs(recipes) do
if recipe.output:sub(1,12) ~= "secretstuff:" then
filtered[#filtered + 1] = recipe
end
end
return filtered
end)
```
#### `craftguide.remove_recipe_filter(name)`
Removes the recipe filter with the given name.
#### `craftguide.set_recipe_filter(name, function(recipe, player))`
Removes all recipe filters and adds a new one.
#### `craftguide.get_recipe_filters()`
Returns a map of recipe filters, indexed by name.

### Search filters
Search filters are used to perform specific searches inside the search field.
They can be used like so: `<optional name>+<filter name>=<value1>,<value2>,<...>`
2019-03-07 13:43:47 +01:00
Examples:
- `+groups=cracky,crumbly`: search for groups `cracky` and `crumbly` in all items.
- `sand+groups=falling_node`: search for group `falling_node` for items which contain `sand` in their names.
2019-03-03 16:20:19 +01:00
Notes:
- If `optional name` is omitted, the search filter will apply to all items, without pre-filtering.
- Filters can be combined.
2019-03-07 13:43:47 +01:00
- The `groups` filter is currently implemented by default.

#### `craftguide.add_search_filter(name, function(item, values))`
Adds a search filter with the given name.
The search function should return a boolean value (whether the given item should be listed or not).
Example function to show items which contain at least a recipe of given width(s):
```lua
craftguide.add_search_filter("widths", function(item, widths)
local has_width
local recipes = recipes_cache[item]
if recipes then
for i = 1, #recipes do
local recipe_width = recipes[i].width
for j = 1, #widths do
local width = tonumber(widths[j])
if width == recipe_width then
has_width = true
break
end
end
end
end
return has_width
end)
```
#### `craftguide.remove_search_filter(name)`
Removes the search filter with the given name.
#### `craftguide.get_search_filters()`
Returns a map of search filters, indexed by name.

### Miscellaneous
#### `craftguide.show(player_name, item, show_usages)`
Opens the Crafting Guide with the current filter applied.
* `player_name`: string param.
* `item`: optional, string param. If set, this item is pre-selected. If the item does not exist or has no recipe, use the player's previous selection. By default, player's previous selection is used
* `show_usages`: optional, boolean param. If true, show item usages.

#### `craftguide.group_stereotypes`
This is the table indexing the item groups by stereotypes.
You can add a stereotype like so:
```Lua
craftguide.group_stereotypes.radioactive = "mod:item"
```
