+API documentation for the HUD bars mod
+======================================
+
+## 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, format_string_config)`
+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 API does not allow fow a custom order or a way to set it
+manually in a reliable way. However, you can use the setting `hudbars_sorting` for this. See the advanced setting menu in Minetest
+for more information.
+
+
+#### 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). This is only used for the `progress_bar` bar type (see `README.txt`, settings section).
+ * `icon`: The file name of the icon, as string. For the `progress_bar` type, it is shown as single image left of the bar, for the two statbar bar types, it is used as the statbar icon and will be repeated. This field can be `nil`, in which case no icon will be used, but this is not recommended, because the HUD bar will be invisible if the one of the statbar bar types is used.
+ * `bgicon`: The file name of the background icon, it is used as the background for the modern statbar mode only. This field can be `nil`, in which case no background icon will be displayed in this mode.
+* `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`: Optional; You can specify an alternative format string to use for the final text on the HUD bar. The default format string is “`@1: @2/@3`” (The “@” numbers are placeholders that have a meaning in this order: @1 = Label, @2 = current value, @3 = maximum value). Do *not* use minetest.translator on this string, the string will be translated by `hudbars`, but you still must put this string into the translation catalogue file.
+* `format_string_config`: Required if `format_string` is set. This allows to change which parameters to use in the format string. It's a table with these fields:
+ * `textdomain`: Text domain of the format string, used by `minetest.translate`
+ * `order`: Table that contains the order of the placeholders. It's also possible to remove placeholders. Default order: `{ "label", "value", "max_value" }`
+ * `format_value`: Format string to apply when displaying `value`. Syntax is same as in `string.format`. Default: `"%d"`
+ * `format_max_value`: Same as `format_value` but is applied to `max_value`
+
+#### Example
+Example (mostly) from `hbarmor` mod:
+
+```
+hb.register_hudbar("armor", 0xFFFFFF, minetest.translator("hbarmor", "Armor"), { icon = "hbarmor_icon.png", bgicon = "hbarmor_bgicon.png", bar = "hbarmor_bar.png" }, 0, 100, hbarmor.autohide, N("@1: @2%"), { order = { "label", "value" }, textdomain = "hbarmor" } )
+```
+
+Displays an armor HUD bar with a label of the form „Armor: 53%“. (`N` is a dummy function that returns its argument, used to make the string visible for translator scripts.)
+
+#### 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
+`true` on success, `false` otherwise.
+
+
+## Modifying a HUD bar
+After a HUD bar has been added, you can change the current and maximum value and other attributes on a per-player basis.
+You use the function `hb.change_hudbar` for this.
+
+### `hb.change_hudbar(player, identifier, new_value, new_max_value, new_icon, new_bgicon, new_bar, new_label, new_text_color)`
+Changes the values and the appearance of an initialized HUD bar for a certain player. `new_value`
+and `new_max_value` are the most important parameters as they specify the new current and maximum new values, you do not need
+to worry too much about the other parameters.
+
+The following parameters are less important and provided for styling the HUD bar after registration (if
+this is desired). The “styling” parameters parallel the parameters of `hb.register_hudbar`. It is
+recommended to not change the style of a HUD bar too often as this can be distracting or confusing
+for players.
+
+`new_value`, `new_max_value` `new_icon`, `new_bgicon`, `new_bar`, `new_label` and `new_text_color` can be
+`nil`; if one of them is `nil`, that means the value is unchanged. If all those values are `nil`, this
+function is a no-op.
+
+This function tries to minimize the amount of calls to `hud_change` of the Minetest Lua API
+(and thus, network traffic), when you only change the value and/or  maximum value. In this case,
+`hud_change` is only called if it is actually needed, e.g. when the actual length of the bar
+or the displayed string changed, so you do not have to worry about it. There is, however, no
+such network optimization for the “styling” parameters, so keep this in mind.
+
+#### 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
+* `new_icon`: File name of the new icon
+* `new_bgicon`: File name of the new background icon for the modern-style statbar
+* `new_bar`: File name of the new bar segment image
+* `new_label`: A new text label of the HUD bar. Note the format string still applies
+* `new_text_color`: A 3-octet number defining the new color of the text.
+
+#### Return value
+`true` on success, `false` otherwise.
+
+
+## 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
+`true` on success, `false` otherwise.
+
+
+### `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
+`true` on success, `false` otherwise.
+
+
+## Reading HUD bar information
+It is also possible to read information about existing HUD bars.
+
+### `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
+On success, returns 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.
+
+If the player does not exist, returns `nil` instead.
+
+### `hb.get_hudbar_identifiers()`
+Returns a table of all currently registered HUD bar identifiers.

+# HUD bars
+
+## Description
+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.
+
+**Important**: Keep in mind if running a server with this mod, that the custom
+position should be displayed correctly on every screen size.
+
+## Current version
+The current version is 2.3.2.
+It works for Minetest 5.3.0.
+
+This software uses [semantic versioning](http://semver.org), as defined by version 2.0.0 of the SemVer
+standard.
+
+## Settings
+This mod can be configured quite a bit. You can change HUD bar appearance, offsets, ordering, and more.
+Use the advanced settings menu in Minetest for detailed configuration.
+
+## 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`.

+[Appearance]
+# Specifies how the value indicators (i.e. health, breah, etc.) look. There are 3 styles
+# available. You can choose between the default progress-bar-like bars and the good
+# old statbars like you know from vanilla Minetest.
+# These values are possible:
+#   - progress_bar:    A horizontal progress-bar-like bar with a label, showing numerical value
+#                      (current, maximum), and an icon. These bars usually convey the most
+#                      information. This is the default and recommended value.
+#   - statbar_classic: Classic statbar, like in vanilla Minetest. Made out of up to 20
+#                      half-symbols. Those bars represent the vague ratio between
+#                      the current value and the maximum value. 1 half-symbol stands for
+#                      approximately 5% of the maximum value.
+#   - statbar_modern:  Like the classic statbar, but also supports background images, this
+#                      kind of statbar may be considered to be more user-friendly than the
+#                      classic statbar. This bar type closely resembles the mod
+#                      “Better HUD” [hud] by BlockMen.

+# between a zig-zag pattern (default) or a vertically stacked pattern.
+# The following values are allowed:
+#    - zigzag:     Starting from the left bottom, the next is right from the first,
+#                  the next is above the first, the next is right of the third, etc.

+# (the default), the health and breath indicators come first, additional indicators
+# may appear in any order. This setting is quite technical and normal users probably do not
+# need to worry about it.
+#
+# Syntax:
+# The setting has to be specified as a comma-seperated list of key=value pairs, where a key
+# refers to the identifier of a HUD bar and the value refers to the slot number of where the
+# HUD bar should be placed. The slot number must be an integer greater of equal to 0. Where
+# the HUD bars will be displayed exactly depends on the alignment pattern being used.
+# All HUD bars to which no order value has been applied will fill in all slots which have
+# not been occupied by the HUD bars specified in this setting, the slots will be filled in
+# from the lowest slot number.
+# Note that the order of those remaining HUD bars is not fixed, it basically just boils
+# down on which mod “came” first. Don't worry, the mod will still work perfectly fine, this
+# setting is entirely optional.
+# The identifier for the health bar is “health” and the identifier for the breath bar is
+# “breath”. For other HUD bars, you have to learn it from the mod which is supplying them.
+#
+# Be careful not to use slot indices twice, or else different HUD bars will be drawn over
+# each other!
+#
+# Example: “breath=0, health=1”
+# This makes the breath bar first and the health bar second, which is the opposite order
+# of the default one.

-# Real Suffocation [`real_suffocation`]
-Version: 1.0.0
-
-This mod adds suffocation. Suffocation is basically the same as drowning, but it
-is for being stuck inside solid blocks. If you're inside a solid block, you lose
-breath. If you lost your breath completely and you're still inside, you suffer
-10 HP (=5 “hearts”) of damage every 2 seconds.
-
-Specifically, suffocation is added to all blocks which:
-
-* Are solid
-* Are full cubes
-* Don't already have built-in damage or drowning damage
-* Are not excluded from suffocations by mods
-
-## Info for modders
-This mod will not add suffocation to all nodes with the group
-`disable_suffocation=1`.
-
-This mod adds the group `real_suffocation=1` to all nodes it has modified,
-this is mostly done for informational purposes.
-
-## License
-Everything is under the MIT license. Forked from https://repo.or.cz/minetest_real_suffocation.git.

-		- Drowning and damage: If node has set any of those explicitly, it probably knows why. We don't want to mess with it.
