+# Simple Fast Inventory
+
+A cleaner, simpler, solution to having an advanced inventory in Minetest.  
+Formspec style based on the creative inventory.
+
+Written by rubenwardy.

+
+## Aims
+
+* Unified Inventory compatible.
+* Themable.
+* Clean API.
+
+# API
+
+## Formspec Parser
+
+sfinv has a variable based parser. Here is the formspec of the crafting tab:
+
+	{{ layout }}
+	list[current_player;craft;1.75,0.5;3,3;]
+	list[current_player;craftpreview;5.75,1.5;1,1;]
+	image[4.75,1.5;1,1;gui_furnace_arrow_bg.png^[transformR270]
+	listring[current_player;main]
+	listring[current_player;craft]
+	image[0,4.25;1,1;gui_hb_bg.png]
+	image[1,4.25;1,1;gui_hb_bg.png]
+	image[2,4.25;1,1;gui_hb_bg.png]
+	image[3,4.25;1,1;gui_hb_bg.png]
+	image[4,4.25;1,1;gui_hb_bg.png]
+	image[5,4.25;1,1;gui_hb_bg.png]
+	image[6,4.25;1,1;gui_hb_bg.png]
+	image[7,4.25;1,1;gui_hb_bg.png]
+
+`{{ layout }}` will be replaced by the following:
+
+	size[8,8.6]
+	bgcolor[#080808BB;true]
+	background[5,5;1,1;gui_formbg.png;true]
+	{{ nav }}
+	listcolors[#00000069;#5A5A5A;#141318;#30434C;#FFF]
+	list[current_player;main;0,4.25;8,1;]
+	list[current_player;main;0,5.5;8,3;8]
+
+and `{{ nav }}` will be replaced by something like the following:
+
+	tabheader[0,0;tabs;Crafting,Page 1, Page 2;1]
+
+Only two levels of variable parsing is guaranteed to succeed, as only two
+passes are done.
+
+Here is another example, this time a page with no inventory:
+
+	size[8,8.6]
+	bgcolor[#080808BB;true]
+	background[5,5;1,1;gui_formbg.png;true]
+	{{ nav }}
+	textlist[0,0;7.85,8.5;help;one,two,three]
+
+The following variables are provided by the API:
+
+* `name` - name of the player viewing
+* `nav` - the navigation, probably a tabset
+* `layout` - a default layout which has the players inventory at the bottom.
+
+
+## sfinv.register_page
+
+sfinv.register_page(name, def)
+
+def is a table containing:
+
+* `title(player, context)` - human readable page name (required)
+* `get(player, context)` - returns a formspec string. See formspec variables. (required)
+* `is_in_nav(player, context)` - return true if it appears in tab header
+* `on_player_receive_fields(player, context, fields)` - on formspec submit
+
+planned:
+
+* `on_enter(player, context)` - when coming to this page from another
+* `on_leave(player, context)` - when leaving this page to go to another
