+Minetest mod: HUD bar for armor [hbarmor]
+=========================================
+Version: 0.1.0
+
+License of source code: WTFPL
+-----------------------------
+By Wuzzy,
+
+forked from the mod “Better HUD (and hunger)” [hud]
+by BlockMen (2013-2014).
+
+
+
+Using the mod:
+--------------
+This mod adds a simple HUD bar which displays the current
+damage of the player's armor (from the 3D Armor mod) as a percentage,
+this number is of course rounded.
+100% means the armor is in perfect shape, 0% means the armor
+is almost destroyed or non-existant.
+Note that to reach 100%, the player must wear at least 4 different
+pieces of armor in perfect shape.
+The armor bar also does not tell anything about the armor's strength,
+only how worn out it already is.
+
+By default, the armor bar is hidden if the player wears no armor.
+
+
+Dependencies:
+- HUD bars [hudbars], major version 1
+- 3D Armor [3d_armor] (tested with 0.4.3)

-Minetest mod "Better HUD"
-=========================
-Version: 1.4
-
-License of source code: WTFPL
------------------------------
-(c) Copyright BlockMen (2013-2014)
-
-
-
-Using the mod:
---------------
-This mod changes the HUD of Minetest. 
-It improves the apperance of the health and breath bar and adds a more fancy hotbar. Furthermore it adds a 
-custom crosshair, an armor bar (only for 3darmor mod) and a hunger bar. It includes also a mechanic for hunger.
-
-You can create a "hud.conf" file to customize the positions of health, hunger, armor and breath bar. Take a look at "hud.conf.example" to get more infos.
-
-
-!!IMPORTANT !!:
-Keep in mind if running a server with this mod, that the custom position should be displayed correct on every screen size!!
-
-
-=Hunger=
-========
-This mod adds a hunger mechanic to the game. Player actions like digging, placing and walking causes exhausion,
-that lowers players saturation. Also every 800 seconds you lose 1 saturation point without doing anything.
-If you are hungry (empty hunger bar) you will get damage and die in case you don't eat something.
-
-
-Notice:
--------
-You can disable this by setting "HUD_HUNGER_ENABLE = false" in "hud.conf", or "hud_hunger_enable = false" in minetest.conf.
-In case of conflict hud.conf configuration is dominant.
-
-
-Currently supported food:
--------------------------
-- Apples (default)
-- Animalmaterials (mobf modpack)
-- Bread (default)
-- Bushes
-- bushes_classic
-- Creatures
-- Dwarves (beer and such)
-- Docfarming
-- Fishing
-- Farming plus
-- Farming (default and Tenplus1's fork)
-- Food
-- fruit
-- Glooptest
-- JKMod
-- kpgmobs
-- Mobfcooking
-- Mooretrees
-- Mtfoods
-- mushroom
-- mush45
-- Seaplants (sea)
-- Simple mobs
-
-Example: 1 apple fills up the hunger bar by 1 bread, 1 bread (from farming) 2 breads in bar.
-
-Although it show 20 hunger points (10 breads) in hunger bar,
-you can fill it up to 30 points.(5 breads not shown then)

+API documentation for the HUD bars mod 1.0.2
+============================================
+
+## Introduction
+This API allows you to add, change, hide and unhide custom HUD bars for this mod.
+
+## Overview
+To give you a *very* brief overview over this API, here is the basic workflow on how to add your own custom HUD bar:
+
+* Create images for your HUD bar
+* Call `hb.register_hudbar` to make the definition of the HUD bar known to this mod
+* Call `hb.init_hudbar` for each player for which you want to use previously defined HUD bar
+* Use `hb.change_hudbar` whenever you need to change the values of a HUD bar of a certain player
+* If you need it: Use `hb.hide_hudbar` and `hb.unhide_hudbar` to hide or unhide HUD bars of a certain player
+
+## The basic rules
+In order to use this API, you should be aware of a few basic rules in order to understand it:
+
+* A HUD bar is an approximate graphical representation of the ratio of a current value and a maximum value, i.e. current health of 15 and maximum health of 20. A full HUD bar represents 100%, an empty HUD bar represents 0%.
+* The current value must always be equal to or smaller then the maximum 
+* Both current value and maximum must not be smaller than 0
+* Both current value and maximum must be real numbers. So no NaN, infinity, etc.
+* The HUD bar will be hidden if the maximum equals 0. This is intentional.
+* The health and breath HUD bars are hardcoded.
+
+These are soft rules, the HUD bars mod will not enforce all of these.
+But this mod has been programmed under the assumption that these rules are followed, for integrity.
+
+## Adding a HUD bar
+To make a new HUD bar known to this mod, you need …
+
+* … an image of size 2×16 for the bar
+* … an icon of size 16×16 (optional)
+* … to register it with `hb.register_hudbar`
+
+### Bar image
+The image for the bar will be repeated horizontally to denote the “value” of the HUD bar.
+It **must** be of size 2×16.
+If neccessary, the image will be split vertically in half, and only the left half of the image
+is displayed. So the final HUD bar will always be displayed on a per-pixel basis.
+
+The default bar images are single-colored, but you can use other styles as well, for instance,
+a vertical gradient.
+
+### Icon
+A 16×16 image shown left of the HUD bar. This is optional.
+
+### `hb.register_hudbar(identifier, text_color, label, textures, default_start_value, default_start_max, default_start_hidden, format_string)`
+This function registers a new custom HUD bar definition to the HUD bars mod, so it can be later used to be displayed, changed, hidden
+and unhidden on a per-player basis.
+Note this does not yet display the HUD bar.
+
+The HUD bars will be displayed in a “first come, first serve” order. This mod does not allow fow a custom order or a way to set it
+manually in a reliable way.
+
+
+#### Parameters
+* `identifier`: A globally unique internal name for the HUD bar, will be used later to refer to it. Please only rely on alphanumeric characters for now. The identifiers “`health`” and “`breath`” are used internally for the built-in health and breath bar, respectively. Please do not use these names.
+* `text_color`: A 3-octet number defining the color of the text. The octets denote, in this order red, green and blue and range from `0x00` (complete lack of this component) to `0xFF` (full intensity of this component). Example: `0xFFFFFF` for white.
+* `label`: A string which is displayed on the HUD bar itself to describe the HUD bar. Try to keep this string short.
+* `textures`: A table with the following fields:
+ * `bar`: The file name of the bar image (as string).
+ * `icon`: The file name of the icon, as string. This field can be `nil`, in which case no icon will be used.
+* `default_start_value`: If this HUD bar is added to a player, and no initial value is specified, this value will be used as initial current value
+* `default_max_value`: If this HUD bar is added to a player, and no initial maximum value is specified, this value will be used as initial maximum value
+* `default_start_hidden`: The HUD bar will be initially start hidden by default when added to a player. Use `hb.unhide_hudbar` to unhide it.
+* `format_string`: This is optional; You can specify an alternative format string display the final text on the HUD bar. The default format string is “`%s: %d/%d`” (in this order: Label, current value, maximum value). See also the Lua documentation of `string.format`.
+
+#### Return value
+Always `nil`.
+
+
+## Displaying a HUD bar
+After a HUD bar has been registered, they are not yet displayed yet for any player. HUD bars must be
+explicitly initialized on a per-player basis.
+
+You probably want to do this in the `minetest.register_on_joinplayer`.
+
+### `hb.init_hudbar(player, identifier, start_value, start_max, start_hidden)`
+This function initialzes and activates a previously registered HUD bar and assigns it to a
+certain client/player. This has only to be done once per player and after that, you can change
+the values using `hb.change_hudbar`.
+
+However, if `start_hidden` was set to `true` for the HUD bar (in `hb.register_hudbar`), the HUD bar
+will initially be hidden, but the HUD elements are still sent to the client. Otherwise,
+the HUD bar will be initially be shown to the player.
+
+#### Parameters
+* `player`: `ObjectRef` of the player to which the new HUD bar should be displayed to.
+* `identifier`: The identifier of the HUD bar type, as specified in `hb.register_hudbar`.
+* `start_value`: The initial current value of the HUD bar. This is optional, `default_start_value` of the registration function will be used, if this is `nil`.
+* `start_max`: The initial maximum value of the HUD bar. This is optional, `default_start_max` of the registration function will be used, if this is `nil`
+* `start_hidden`: Whether the HUD bar is initially hidden. This is optional, `default_start_hidden` of the registration function will be used as default
+
+#### Return value
+Always `nil`.
+
+
+
+## Modifying a HUD bar
+After a HUD bar has been added, you can change the current and maximum value on a per-player basis.
+You use the function `hb.change_hudbar` for this.
+
+### `hb.change_hudbar(player, identifier, new_value, new_max_value)`
+Changes the values of an initialized HUD bar for a certain player. `new_value` and `new_max_value`
+can be `nil`; if one of them is `nil`, that means the value is unchanged. If both values
+are `nil`, this function is a no-op.
+This function also tries minimize the amount of calls to `hud_change` of the Minetest Lua API, and
+therefore, network traffic. `hud_change` is only called if it is actually needed, i.e. when the
+actual length of the bar or the displayed string changed, so you do not have to worry about it.
+
+#### Parameters
+* `player`: `ObjectRef` of the player to which the HUD bar belongs to
+* `identifier`: The identifier of the HUD bar type to change, as specified in `hb.register_hudbar`.
+* `new_value`: The new current value of the HUD bar
+* `new_max_value`: The new maximum value of the HUD bar
+
+#### Return value
+Always `nil`.
+
+
+## Hiding and unhiding a HUD bar
+You can also hide custom HUD bars, meaning they will not be displayed for a certain player. You can still
+use `hb.change_hudbar` on a hidden HUD bar, the new values will be correctly displayed after the HUD bar
+has been unhidden. Both functions will only call `hud_change` if there has been an actual change to avoid
+unneccessary traffic.
+
+Note that the hidden state of a HUD bar will *not* be saved by this mod on server shutdown, so you may need
+to write your own routines for this or by setting the correct value for `start_hidden` when calling
+`hb.init_hudbar`.
+
+### `hb.hide_hudbar(player, identifier)`
+Hides the specified HUD bar from the screen of the specified player.
+
+#### Parameters
+* `player`: `ObjectRef` of the player to which the HUD bar belongs to
+* `identifier`: The identifier of the HUD bar type to hide, as specified in `hb.register_hudbar`.
+
+#### Return value
+Always `nil`.
+
+
+### `hb.unhide_hudbar(player, identifier)`
+Makes a previously hidden HUD bar visible again to a player.
+
+#### Parameters
+* `player`: `ObjectRef` of the player to which the HUD bar belongs to
+* `identifier`: The identifier of the HUD bar type to unhide, as specified in `hb.register_hudbar`.
+
+#### Return value
+Always `nil`.
+
+
+## Reading HUD bar information
+It is also possible to read information about an active HUD bar.
+
+### `hb.get_hudbar_state(player, identifier)`
+Returns the current state of the active player's HUD bar.
+
+#### Parameters
+* `player`: `ObjectRef` of the player to which the HUD bar belongs to
+* `identifier`: The identifier of the HUD bar type to hide, as specified in `hb.register_hudbar`.
+
+#### Return value
+A table which holds information on the current state of the HUD bar. Note the table is a deep
+copy of the internal HUD bar state, it is *not* a reference; the information hold by the table is
+only true for the moment you called this function. The fields of this table are:
+
+* `value`: Current value of HUD bar.
+* `max`: Current maximum value of HUD bar.
+* `hidden`: Boolean denoting whether the HUD bar is hidden.
+* `barlength`: The length of the HUD bar in pixels. This field is meaningless if the HUD bar is currently hidden.
+* `text`: The text shown on the HUD bar. This fiels is meaningless if the HUD bar is currently hidden.

+Minetest mod: HUD bars
+======================
+Version: 1.0.2
+
+This software uses semantic versioning, as defined by version 2.0.0 of the SemVer
+standard. <http://semver.org/>
+
+
+License of source code: WTFPL
+-----------------------------
+Author: Wuzzy (2015)
+Forked from the “Better HUD” [hud] mod by BlockMen.
+
+
+Using the mod:
+--------------
+This mod changes the HUD of Minetest. It replaces the default health and breath symbols by horizontal colored bars with text showing
+the number.
+
+Furthermore, it enables other mods to add their own custom bars to the HUD, this mod will place them accordingly.
+
+You can create a “hudbars.conf” file to customize the positions of the health and breath bars. Take a look at “hudbars.conf.example”
+to get more infos. The lines starting with “--” are comments, remove the two dashes to activate a setting. Settings which are not
+set will use a default value instead.
+
+
+IMPORTANT:
+Keep in mind if running a server with this mod, that the custom position should be displayed correctly on every screen size!
+
+API:
+----
+The API is used to add your own custom HUD bars.
+Documentation for the API of this mod can be found in API.md.
