or checking if a mod is enabled.
* `minetest.get_modnames()`: returns a list of enabled mods, sorted alphabetically.
* Does not include disabled mods, even if they are installed.
+* `minetest.get_game_info()`: returns a table containing information about the

+ can be manually read from `game.conf` in the game's root directory.
+
+ {

* `minetest.get_worldpath()`: returns e.g. `"/home/user/.minetest/world"`
* Useful for storing custom data
* `minetest.is_singleplayer()`
* `pos_list` is an array of all modified positions.
* `node_list` is an array of the old node that was previously at the position
with the corresponding index in pos_list.
+* `minetest.register_on_mapblocks_changed(function(modified_blocks, modified_block_count))`
+ * Called soon after any nodes or node metadata have been modified. No
+ modifications will be missed, but there may be false positives.
+ * Will never be called more than once per server step.
+ * `modified_blocks` is the set of modified mapblock position hashes. These
+ are in the same format as those produced by `minetest.hash_node_position`,
+ and can be converted to positions with `minetest.get_position_from_hash`.
+ The set is a table where the keys are hashes and the values are `true`.
+ * `modified_block_count` is the number of entries in the set.
+ * Note: callbacks must be registered at mod load time.

prefix `"no"` is attached, clears instead.
* `flags` is in the same format and has the same options as `mg_flags` in
`minetest.conf`.
+* `minetest.get_mapgen_edges([mapgen_limit[, chunksize]])`
+ * Returns the minimum and maximum possible generated node positions
+ in that order.
+ * `mapgen_limit` is an optional number. If it is absent, its value is that
+ of the *active* mapgen setting `"mapgen_limit"`.
+ * `chunksize` is an optional number. If it is absent, its value is that
+ of the *active* mapgen setting `"chunksize"`.
* `minetest.get_mapgen_setting(name)`
* Gets the *active* mapgen setting (or nil if none exists) in string
format with the following order of precedence:
* You may want to cache and call the old function to allow multiple mods to
change knockback behavior.
-* `minetest.forceload_block(pos[, transient])`
+* `minetest.forceload_block(pos[, transient[, limit]])`
* forceloads the position `pos`.
* returns `true` if area could be forceloaded
* If `transient` is `false` or absent, the forceload will be persistent
(saved between server runs). If `true`, the forceload will be transient
(not saved between server runs).
+ * `limit` is an optional limit on the number of blocks that can be
+ forceloaded at once. If `limit` is negative, there is no limit. If it is
+ absent, the limit is the value of the setting `"max_forceloaded_blocks"`.
+ If the call would put the number of blocks over the limit, the call fails.
* `minetest.forceload_free_block(pos[, transient])`
* stops forceloading the position `pos`
Base class used by [`StorageRef`], [`NodeMetaRef`], [`ItemStackMetaRef`],
and [`PlayerMetaRef`].
+Note: If a metadata value is in the format `${k}`, an attempt to get the value
+will return the value associated with key `k`. There is a low recursion limit.
+This behavior is **deprecated** and will be removed in a future version. Usage
+of the `${k}` syntax in formspecs is not deprecated.

### Methods
* `contains(key)`: Returns true if key present, otherwise false.
* Resource intensive - use sparsely
* `set_lighting(light_definition)`: sets lighting for the player
* `light_definition` is a table with the following optional fields:
+ * `saturation` sets the saturation (vividness).
+ values > 1 increase the saturation
+ values in [0,1) decrease the saturation
+ * This value has no effect on clients who have the "Tone Mapping" shader disabled.
* `shadows` is a table that controls ambient shadows
* `intensity` sets the intensity of the shadows from 0 (no shadows, default) to 1 (blackness)
+ * This value has no effect on clients who have the "Dynamic Shadows" shader disabled.
+ * `exposure` is a table that controls automatic exposure.
+ The basic exposure factor equation is `e = 2^exposure_correction / clamp(luminance, 2^luminance_min, 2^luminance_max)`
+ * `luminance_min` set the lower luminance boundary to use in the calculation
+ * `luminance_max` set the upper luminance boundary to use in the calculation
+ * `exposure_correction` correct observed exposure by the given EV value
+ * `speed_dark_bright` set the speed of adapting to bright light
+ * `speed_bright_dark` set the speed of adapting to dark scene
+ * `center_weight_power` set the power factor for center-weighted luminance measurement
+
* `get_lighting()`: returns the current state of lighting for the player.
* Result is a table with the same fields as `light_definition` in `set_lighting`.
* `respawn()`: Respawns the player using the same mechanism as the death screen,
-- If left out or empty, any neighbor will do.
-- `group:groupname` can also be used here.

+Note that in params, the conventional use of symbols is as follows:
* `<>` signifies a placeholder to be replaced when the command is used. For
example, when a player name is needed: `<name>`
* `()` signifies grouping. For example, when param1 and param2 are both
required, or only param3 is required: `(<param1> <param2>) | <param3>`
+Example:
+
+ {
+ params = "<name> <privilege>",

Privilege definition
--------------------
All of the properties in this list can be animated with `*_tween` tables
unless otherwise specified. For example, `jitter` can be tweened by setting
a `jitter_tween` table instead of (or in addition to) a `jitter` table/value.
+In this section, a float range is a table defined as so: { min = A, max = B }
+A and B are your supplemented values. For a vec3 range this means they are vectors.
Types used are defined in the previous section.
* vec3 range `pos`: the position at which particles can appear

+Error Handling
+--------------
+
+When an error occurs that is not caught, Minetest calls the function
+`minetest.error_handler` with the error object as its first argument. The second
+argument is the stack level where the error occurred. The return value is the
+error string that should be shown. By default this is a backtrace from
+`debug.traceback`. If the error object is not a string, it is first converted
+with `tostring` before being displayed. This means that you can use tables as
+error objects so long as you give them `__tostring` metamethods.
+
+You can override `minetest.error_handler`. You should call the previous handler
+with the correct stack level in your implementation.
