# ![Preview1](http://i.imgur.com/fIPNYkb.png) Crafting Guide
#### `craftguide` is the most comprehensive crafting guide on Minetest.
#### Consult the [Minetest Wiki](http://wiki.minetest.net/Crafting_guide) for more details.
This crafting guide is a blue book named *"Crafting Guide"* or a wooden sign.
This crafting guide features a **progressive mode**.
The progressive mode is a Terraria-like system that only shows recipes you can craft from items in inventory.
The progressive mode can be enabled with `craftguide_progressive_mode = true` in `minetest.conf`.
`craftguide` is also integrated in `sfinv` (Minetest Game inventory) when you enable it with
`craftguide_sfinv_only = true` in `minetest.conf`.
Use the command `/craft` to show the recipe(s) of the pointed node.

## API
### Custom recipes
#### Registering a custom crafting type
```Lua
craftguide.register_craft_type("digging", {
description = "Digging",
icon = "default_tool_steelpick.png",
})
```
#### Registering a custom crafting recipe
```Lua
craftguide.register_craft({
type = "digging",
width = 1,
output = "default:cobble 2",
items = {"default:stone"},
})
```
### Progressive mode
#### `craftguide.add_progressive_filter(function(recipes, player))`
This function adds a recipe filter when progressive mode is enabled.
The default `craftguide` filter will still be used.
Example function to hide recipes for items from a mod called "secretstuff":
```lua
craftguide.add_progressive_filter(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.set_progressive_filter(function(recipes, player))`
This function sets an unique recipes filter when progressive mode is enabled.
The default `craftguide` progressive filter will be overridden.
#### `craftguide.get_progressive_filters()`
This function returns all progressive filters that are applied to recipes in progressive mode.
