^- called when a train leaves the rail
-- The following function is only in effect when interlocking is enabled:
on_train_approach = function(pos, train_id, train, index, lzbdata)
on_train_approach = function(pos, train_id, train, index, has_entered, lzbdata)
^- called when a train is approaching this position, called exactly once for every path recalculation (which can happen at any time)
^- This is called so that if the train would start braking now, it would come to halt about(wide approx) 5 nodes before the rail.
^- has_entered: when true, the train is already standing on this node with its front tip, and the enter callback has already been called.
Possibly, some actions need not to be taken in this case. Only set if it's the very first node the train is standing on.
^- lzbdata should be ignored and nothing should be assigned to it

When speed has dropped below, say 3, decrease the margin to zero, so that trains actually stop at the signal IP.
The spd variable and travsht need to be updated on every aspect change. it's probably best to reset everything when any aspect changes
The LZB subsystem keeps track of "checkpoints" the train will pass in the future, and has two main tasks:
1. run approach callbacks, and run callbacks when passing LZB checkpoints
2. keep track of the permitted speed at checkpoints, and make sure that the train brakes accordingly
To perform 2, it populates the train.path_speed table which is handled along with the path subsystem.
This table is used in trainlogic.lua/train_step_b() and applied to the velocity calculations.
Note: in contrast to node enter callbacks, which are called when the train passes the .5 index mark, LZB callbacks are executed on passing the .0 index mark!
If an LZB checkpoint has speed 0, the train will still enter the node (the enter callback will be called), but will stop at the 0.9 index mark (for details, see SLOW_APPROACH in trainlogic.lua)
The start point for the LZB traverser (and thus the first node that will receive an approach callback) is floor(train.index) + 1. This means, once the LZB checkpoint callback has fired,
this path node will not receive any further approach callbacks for the same approach situation

This mod offers components that run LUA code and interface with each other through a global environment. It makes complex automated railway systems possible. The mod is sometimes abbreviated as 'atlatc'. This stands for AdvTrainsLuaATC. This short name has been chosen for user convenience, since the name of this mod ('advtrains_luaautomation') is very long.
This mod offers components that run LUA code and interface with each other through a global environment. It makes complex automated railway systems possible. The mod is sometimes abbreviated as 'LuaATC' or 'atlatc'. This stands for AdvTrainsLuaATC. This short name has been chosen for user convenience, since the name of this mod ('advtrains_luaautomation') is very long.
A probably more complete documentation of LuaATC is found on the [Advtrains Wiki](http://advtrains.de/wiki/doku.php?id=usage:atlatc:start)

Any attempt to overwrite the predefined values results in an error.
## Components and Events
### Components
Atlac components introduce automation-capable components that fall within two categories:
- Active Components are components that are able to run Lua code, triggered by specific events.
- Passive Components can't perform actions themselves. Their state can be read and set by active components or manually by the player.
## Functions and Variables
### Events
The event table is a variable created locally by the component being triggered. It is a table with the following format:
```lua
event = {
type = "<event type>",
<event type> = true,
--additional event-specific content
}
```
You can check the event type by using the following:
```lua
if event.type == "wanted" then
--do stuff
end
```
or
```lua
if event.wanted then
--do stuff
end
````
where `wanted` is the event type to check for.
See the "Active Components" section below for details on the various event types as not all of them are applicable to all components.
### LuaAutomation Global Variables
- `S`
The variable 'S' contains a table which is shared between all components of the environment. Its contents are persistent over server restarts. May not contain functions, every other value is allowed.

### Active Component
#### Lua ATC Rails
Lua ATC rails are the only components that can actually interface with trains. The following event types are available to the Lua ATC rails:
- ```lua
{type="train", train=true, id="<train_id>"}
#### Lines
The advtrains_line_automation component adds a few contraptions that should make creating timeable systems easier.
Part of its functionality is also available in LuaATC:
- `rwt.*` - all Railway Time functions are included as documented in [the wiki](https://advtrains.de/wiki/doku.php?id=dev:lines:rwt)
- `schedule(rw_time, msg)`, `schedule_in(rw_dtime, msg)`
Schedules an event of type {type="schedule", schedule=true, msg=msg} at (resp. after) the specified railway time (which can be in any format). You can only schedule one event this way. (uses the new lines-internal scheduler)
Note: Using the lines scheduler is preferred over using `interrupt()`, as it's more performant and safer to use.
## Events
The event table is a variable created locally by the component being triggered. It is a table with the following format:
```lua
event = {
type = "<event type>",
<event type> = true,
--additional event-specific content
}
```
You can check the event type by using the following:
```lua
if event.type == "wanted" then
--do stuff
end
```
or
```lua
if event.wanted then
--do stuff
end
```
where `wanted` is the event type to check for.
See the "Active Components" section below for details on the various event types as not all of them are applicable to all components.
## Components
Atlac components introduce automation-capable components that fall within two categories:
- Active Components are components that are able to run Lua code, triggered by specific events.
- Passive Components can't perform actions themselves. Their state can be read and set by active components or manually by the player.
### Lua ATC Rails
Lua ATC rails are the only components that can actually interface with trains. The following event types are available to the Lua ATC rails:
- `{type="train", train=true, id="<train_id>"}`
* This event is fired when a train enters the rail. The field `id` is the unique train ID, which is 6-digit random numerical string.
* If the world contains trains from an older advtrains version, this string may be longer and contain a dot `.`
- ```lua
{type="int", int=true, msg=<message>}
```
- `{type="int", int=true, msg=<message>}`
* Fired when an interrupt set by the `interrupt` function runs out. `<message>` is the message passed to the interrupt function.
* For backwards compatiblity reasons, `<message>` is also contained in an `event.message` variable.
- ```lua
{type="ext_int", ext_int=true, message=<message>}
```
- `{type="ext_int", ext_int=true, message=<message>}`
* Fired when another node called `interrupt_pos` on this position. `message` is the message passed to the interrupt_pos function.
- ```lua
{type="digiline", digiline=true, channel=<channel>, msg=<message>}
```
- `{type="digiline", digiline=true, channel=<channel>, msg=<message>}`
* Fired when the controller receives a digiline message.

Deprecated:

deprecated aliases for set_autocouple() and unset_autocouple(), will be removed from a later release.
##### Timetable Automation
#### Interlocking
This additional function is available when advtrains_interlocking is enabled:
- `atc_set_disable_ars(boolean)`
Disables (true) or enables (false) the use of ARS for this train. The train will not trigger ARS (automatic route setting) on signals then.
Note: If you want to disable ARS from an approach callback, the call to `atc_set_disable_ars(true)` *must* happen during the approach callback, and may not be deferred to an interrupt(). Else the train might trigger an ARS before the interrupt fires.
#### Approach callbacks
The LuaATC interface provides a way to hook into the approach callback system, which is for example used in the TSR rails (provided by advtrains_interlocking) or the station tracks (provided by advtrains_lines). However, for compatibility reasons, this behavior needs to be explicitly enabled.
Enabling the receiving of approach events works by setting a variable in the local environment of the ATC rail, by inserting the following code:
```lua
__approach_callback_mode = 1
-- to receive approach callbacks only in arrow direction
-- or alternatively
__approach_callback_mode = 2
-- to receive approach callbacks in both directions
```
The following event will be emitted when a train approaches:
```lua
{type="approach", approach=true, id="<train_id>"}
```
Please note these important considerations when using approach callbacks:
- Approach events might be generated multiple times for the same approaching train. If you are using atc_set_lzb_tsr(), you need to call this function on every run of the approach callback, even if you issued it before for the same train.
- A reference to the train is available while executing this event, so that functions such as atc_send() or atc_set_text_outside() can be called. On any consecutive interrupts, that reference will no longer be available until the train enters the track ("train" event)
- Unlike all other callbacks, approach callbacks are executed synchronous during the train step. This may cause unexpected side effects when performing certain actions (such as switching turnouts, setting signals/routes) from inside such a callback. I strongly encourage you to only run things that are absolutely necessary at this point in time, and defer anything else to an interrupt(). Be aware that certain things might trigger unexpected behavior.
Operations that are safe to execute in approach callbacks:
- anything related only to the global environment (setting things in S)
- digiline_send()
- atc_set_text_*()
- atc_set_lzb_tsr() (see below)
In the context of approach callbacks, one more function is available:
- `atc_set_lzb_tsr(speed)`
Impose a Temporary Speed Restriction at the location of this rail, making the train pass this rail at the specified speed. (Causes the same behavior as the TSR rail)

#### Operator panel
### Operator panel
This simple node executes its actions when punched. It can be used to change a switch and update the corresponding signals or similar applications. It can also be connected to by the`digilines` mod.
The event fired is `{type="punch", punch=true}` by default. In case of an interrupt or a digiline message, the events are similar to the ones of the ATC rail.
#### Init code
### Init code
The initialization code is not a component as such, but rather a part of the whole environment. It can (and should) be used to make definitions that other components can refer to.

I<8 S8 ;
If the train is slower than 8, accelerate to 8.
# ATC controller operation modes
static: Only give 1 static command.
# Interlocking
mesecon: Give 2 different commands depending on if the controller is mesecon-powered or not
digiline: Don't give any commands by itself. When a train passes, a digiline message in the form of "[+/-][speed]" is sent on the set channel (where +/- means the same as with conditions). Any digiline message sent to the controller will be interpreted as ATC command and sent to the train.
** the latter two are not yet implemented.
With advtrains_interlocking, there's one more available command:
A0
Disable ARS on the train.
A1
Enable ARS on the train.
When disabled, the train will not trigger automatic route setting on signals based on ARS.
# Persistence
ATC controllers that are configured as 'static' or 'mesecon' are persistent over mapblock unloads and will even command the train when the mapblock is unloaded. This is not possible with digilines since these do not work in unloaded mapchunks.
