Includes are similar to function calls in the syntax, but are directly handled by the config parser. They are only allowed in action context, as they insert a reference to an action block at the point they are used.
There are three types of includes:
* @include "/etc/lighttpd/vhosts/*.conf";@: include files like the main config itself; the path can contain wildcards
* @include_shell "/etc/lighttpd/config_generator.sh";@: runs the specified command, and parses the output of it as config file
* @include_lua "/etc/lighttpd/complex.lua"@: includes a Lua config file
* @include_lua "/etc/lighttpd/complex.lua"@: includes a Lua config file. The single action to be executed must be returned in the global @actions@ variable (or leave it empty to do nothing). See also "@lua.handler@":mod_lua.html#mod_lua__action_lua-handler
Includes also create a new nested scope.

lighttpd2 consists of two main binaries: the angel (@lighttpd2@) and the worker (@lighttpd2-worker@). The "main configuration":core_config.html#core_config is used by the worker, and this chapter describes the configuration for the angel.
A standard distribution should install a angel config with reasonable defaults which should work for most basic setups.

<section title="Running lighttpd2">
<textile><![CDATA[
You need two config files for lighttpd, which are usually in the following two locations:
* "@/etc/lighttpd2/lighttpd.conf@":http://git.lighttpd.net/lighttpd/lighttpd2.git/tree/contrib/lighttpd.conf: the main config, see "Main Configuration":core_config.html#core_config. It can be splitted into multiple files, see "Includes":core_config.html#core_config__includes.
* "@/etc/lighttpd2/angel.conf@":http://git.lighttpd.net/lighttpd/lighttpd2.git/tree/contrib/angel.conf: the angel config, see "Angel Configuration":core_config_angel.html#core_config_angel.
The "@contrib/@":http://git.lighttpd.net/lighttpd/lighttpd2.git/tree/contrib directory in the sources includes example config files.
Then start lighttpd2 with:
<pre>/usr/sbin/lighttpd2 -c /etc/lighttpd2/angel.conf</pre>
The process will not fork into background, you need to do that yourself if you want that.
Our recommended way to run lighttpd2 is "runit":http://smarden.org/runit/useinit.html (have a look at the "@contrib/service@":http://git.lighttpd.net/lighttpd/lighttpd2.git/tree/contrib/service directory).

<textile>
Lua can be used to generate configs (like a shortcut to "@include_shell@":core_config.html#core_config__includes) or to write actual response handlers.
Using Lua to generate configs doesn't have any performance impact; in this case Lua is only run at startup to generate the config, and there is no Lua involved for processing requests.
As a @lua_State@ itself is not thread-safe, you have two ways to use Lua configs:
* "@include_lua@":core_config.html#core_config__includes and "@lua.plugin@":mod_lua.html#mod_lua__setup_lua-plugin : using a global server lock, but with sharing the same @lua_State@ in all workers
* "@lua_handler@":mod_lua.html#mod_lua__action_lua-handler: without locking, and every worker has its own @lua_State@ (and they cannot share their global context).

<section title="Lua Config">

This section describe how to translate concepts from the main config to Lua. You can write the whole config in Lua or only parts and include them (for example with "@include_lua@":core_config.html#core_config__includes).

<textile><![CDATA[
* Boolean: Lua supports @true@ and @false@ directly
* Integers: Lua has its own number type (usually a "@double@":http://en.wikipedia.org/wiki/Double-precision_floating-point_format), and doesn't know any of the suffixes.
* Strings: Lua supports strings directly. Check the Lua reference for the various quoting styles.
* Lists and Key-Value-Lists: Lua has a "table" type; it can contain sequential lists and associative mappings. Use @{1, 2, 3}@ to create simple lists, @{a=1, b=2}@ to create unique mappings (which get converted to Key-Value-Lists) or @{{"a",1},{"a",2}}@ to explicitly create Key-Value-Lists (where a key can be used more than once and the order matters).
Don't mix sequential lists and associative mappings.
If you get a List (possible a Key-Value-List) value from lighttpd it is represented as sequential list but has a special @__index@ meta-table method supporting strings and @nil@ as lookup parameter, i.e. you can treat a Key-Value-List like an associative mapping in Lua (see for example the options handling in "contrib/secdownload.lua":http://git.lighttpd.net/lighttpd/lighttpd2.git/tree/contrib/secdownload.lua).
* Expressions and variables just are the usual Lua things; there is no direct access to the lighttpd config variables (yet).
* Action blocks: you can make an action from a list of actions using the "list action":plugin_core.html#plugin_core__action_list (@act = action.list(act1, act2)@)

<section title="Function calls">
<textile><![CDATA[
Action context is given by prefixing the function name with @action.@, and setup context by prefixing with @setup.@. Don't try to call setups in request handling.
Also each Lua function can act as an action (see the debug.lua example above), taking a virtual request object as parameter.
Includes are not supported, neither is the debug @__print@ (there are other logging methods available).

<section title="Conditions">
<textile><![CDATA[
Conditions are the ugliest part: there is no way translating native Lua if statements into the lighttpd config, so they need to be constructed manually.
Only the long names of the condition variables are available in Lua. The condition operators are all given names and appended to the condition variable, and then called with the value to compare with.

<section title="API">
<textile><![CDATA[
This section documents the object types you need to handle requests; you will probably start from the Virtual Request object you get as parameter in your handler.
Object fields should be accessed with @.field@ or @["field"]@, for example:
<pre>
e = vr.env
e["XXX"] = "abc"
</pre>
Fields tagged with (ro) are read only; that does not mean the fields value can't be modified, you only cannot overwrite the field with another object. Readonly string / number properties are really read only though.
Call object methods with @:method(...)@:
<pre>
vr:print("Hello World")
</pre>
*Note*:
The @obj:method(par1, par2, ...)@ syntax is just another way to say @obj["method"](obj, par1, par2, ...)@ (but @obj@ is only evaluated once), so field and method names live in the same namespace.
This means that our container types cannot provide access to fields which have the same names as the methods (and the methods starting with "__" are not listed here), so you have to use explicit access methods to read generic fields in such containers (write is not a problem as we don't allow writing methods).
All container types should provide a @get@ and a @set@ method to provide "clean" access to the container contents.
h3. pairs()
Some objects may provide a @:pairs()@ method to loop through the fields (not the methods); this works for simple things like
<pre>
for k, v in vr.env:pairs() do
vr:print("env['" .. k .. "'] = '" .. v .. "'")
end
</pre>
lua expects that the @:pairs@ method returns a @next, obj, startkey@ tuple and loops through the list with @k = startkey; while k, v = next(obj, k) do ... end@; but the @next()@ method is supposed to use @k@ as previous key and to return the next one.
Our @next@ methods will keep the current position in an internal object (associated with the @next@ function as upvalue), and will advance on every call ignoring the @obj@ and @k@ parameter.

lua.handler is basically the same as "include_lua":plugin_core.html#plugin_core__action_include_lua with the following differences:
lua.handler is basically the same as "include_lua":core_config.html#core_config__includes with the following differences:
* each worker loads the lua file itself
* it isn't loaded before it is used, so you won't see errors in the script at load time
* it cannot call setup functions
* it supports arguments to the script (@local filename, args = ...@)
* doesn't lock the global lua lock, so it performs better when you use multiple workers
