-# Display API
-This document describes Display API. Display API allows to add a dynamic display on a node. Display API limits node rotations. For wallmounted, only vertical positionning is available. For facedir, only first four position are availabel (those with default axis).
-
-## Provided methods
-### update\_entities
-**display\_api.update\_entities(pos)**
-
-This method triggers entities update for the display node at pos. Actual entity update is made by `on_display_update` callback associated to the entity.
-
-`pos`: Position of the node
-### register\_display\_entity
-**display\_api.register\_display\_entity(entity_name)**
-
-This is a helper to register entities used for display.
-
-`entity_name`: Name of the entity to register.
-
-## Provided callback implementations
-### on_place
-**display\_api.on\_place(itemstack, placer, pointed\_thing)**
-
-`on_place` node callback implementation. Display nodes should have this callback (avoid placement of horizontal display node).
-### on_construct
-**display\_api.on\_construct(pos)**
-
-`on_construct` node callback implementation. Display nodes should have this callback (creates, places and updates display entities on node construction).
-### on_destruct
-**display\_api.on_destruct(pos)**
-
-`on_destruct` node callback implementation. Display nodes should have this callback (removes display entities on node destruction).
-### on_rotate
-**display\_api.on\_rotate(pos, node, user, mode, new_param2)**
-
-`on_rotate` node callback implementation. Display nodes should have this callback (restricts rotations and rotates display entities associated with node).
-### on_activate
-**display\_api.on_activate(entity, staticdata)**
-
-`On_activate` entity callback implementation for display entities. No need of this method if display entities have been registered using `register_display_entity` (callback is already set).
-
-## Howto register a display node
-* Register display entities with `register_display_entity`
-
-* Register node with :
-  - `on_place`, `on_construct`, `on_destruct` and `on_rotate` callbacks using display_api callbacks.\
-  - `display_api` group. This will make this node have their entities updated as soon as the mapblock is loaded (Useful after /clearobjects).\
-  - a `display_entities` field in node definition containing a entity name indexed table. See below for description of each display_entities fields.\
-
-### Display_entities fields
-`on_display_update` is a callback in charge of setting up entity texture. If not set, entity will have no texture and will be displayed as unknown item.\
-`depth`, `right` and `top`: Entity position regarding to node facedir/wallmounted main axis.\
-Values for these fields can be any number between -1.5 and 1.5 (default value is 0). Position 0,0,0 is the center of the node.\
-`depth` goes from front (-0.5) to rear (0.5), `top` goes from bottom (-0.5) to top (0.5) and `right` goes from left (-0.5) to right (0.5).\
-`yaw`: Entity yaw in radians, regarding to main axis. Default is 0, aligned to node face.
-
-In order to avoid flickering text, it's better to have text a little behind node surface. A good spacing value is given by `display_api.entity_spacing` variable.
-
-### Example
-
-	display_api.register_display_entity("mymod:entity1")
-	display_api.register_display_entity("mymod:entity2")
-
-	function my_display_update1(pos, objref)
-		objref:set_properties({ textures= {"mytexture1.png"},
-		                        visual_size = {x=1, y=1} })
-	end
-
-	function my_display_update2(pos, objref)
-		objref:set_properties({ textures= {"mytexture2.png"},
-		                        visual_size = {x=1, y=1} })
-	end
-
-	minetest.register_node("mymod:test_display_node", {
-		...
-		paramtype2 = "facedir",
-		...
-		groups = { display_api = 1, ... },
-		...
-		display_entities = {
-			["mymod:entity1"] = {
-				depth = 0.3,
-				on_display_update = my_display_update1 },
-			["mymod:entity1"] = {
-				depth = 0.2, top = 0.1,
-				on_display_update = my_display_update2 },
-			},
-		...
-		on_place = display_api.on_place,
-		on_construct = display_api.on_construct,
-		on_destruct = display_api.on_destruct,
-		on_rotate = display_api.on_rotate,
-		...
-	})

-without being bound by section 3 of the GNU GPL.
-
-  2. Conveying Modified Versions.
-
-  If you modify a copy of the Library, and, in your modifications, a

-   d) Do one of the following:
-
-       0) Convey the Minimal Corresponding Source under the terms of this
-       License, and the Corresponding Application Code in a form
-       suitable for, and under terms that permit, the user to
-       recombine or relink the Application with a modified version of
-       the Linked Version to produce a modified Combined Work, in the
-       manner specified by section 6 of the GNU GPL for conveying
-       Corresponding Source.
-
-       1) Use a suitable shared library mechanism for linking with the

-   you use option 4d0, the Installation Information must accompany
-   the Minimal Corresponding Source and Corresponding Application
-   Code. If you use option 4d1, you must provide the Installation
-   Information in the manner specified by section 6 of the GNU GPL

-
-   a) Accompany the combined library with a copy of the same work based
-   on the Library, uncombined with any other library facilities,
-   conveyed under the terms of this License.
-
-   b) Give prominent notice with the combined library that part of it
-   is a work based on the Library, and explaining where to find the
-   accompanying uncombined form of the same work.
-
-  6. Revised Versions of the GNU Lesser General Public License.
-
-  The Free Software Foundation may publish revised and/or new versions
-of the GNU Lesser General Public License from time to time. Such new
-versions will be similar in spirit to the present version, but may
-differ in detail to address new problems or concerns.
-
-  Each version is given a distinguishing version number. If the
-Library as you received it specifies that a certain numbered version
-of the GNU Lesser General Public License "or any later version"
-applies to it, you have the option of following the terms and
-conditions either of that published version or of any later version
-published by the Free Software Foundation. If the Library as you
-received it does not specify a version number of the GNU Lesser
-General Public License, you may choose any version of the GNU Lesser
-General Public License ever published by the Free Software Foundation.
-
-  If the Library as you received it specifies that a proxy can decide
-whether future versions of the GNU Lesser General Public License shall
-apply, that proxy's public statement of acceptance of any version is
-permanent authorization for you to choose that version for the
-Library.

-# Display API
-
-This library's purpose is to ease creation of nodes with one or more displays on sides. For example, signs and clocks. Display can be dynamic and/or different for each node instance.
-
-**Limitations**: This lib uses entities to draw display. This means display has to be vertical (and "upside up") on Minetest before version 5.0.
-
-**Dependancies**:default
-
-**License**: LGPLv2
-
-**API**: See [API.md](https://github.com/pyrollo/display_modpack/blob/master/display_api/API.md) document please.
-
-For more information, see the [forum topic](https://forum.minetest.net/viewtopic.php?t=19365) at the Minetest forums.

-* `display_lib_node` group (use `display_api` group instead);
-* `display_lib` global table (use `display_api` global table instead);
-
-These objects will be removed in the future.
-
-## Change log
-### 2019-03-14
-- __dispay_api__: Display API now detects automatically whenr rotation restrictions have to be applied.
-
-### 2019-03-09
-- __display_api__: Display nodes can be rotated in every directions (if running Minetest 5 or above).
