# This file defines all supported Nginx configuration options. The
# build system automatically generates the corresponding Nginx module boilerplate
# code from the definitions in this file.
#
# Main configuration options are not defined in this file, but are defined in
# src/nginx_module/Configuration.c instead.
#
# The following boilerplate code is generated:
#
# * ngx_command_t array members (ConfigGeneral/AutoGeneratedDefinitions.c.cxxcodebuilder)
# * Configuration structure definition ({MainConfig,LocationConfig}/AutoGeneratedStruct.h.cxxcodebuilder)
# * Configuration structure initialization ({MainConfig/LocationConfig}/AutoGeneratedCreateFunction.c.cxxcodebuilder)
# * Configuration merging (LocationConfig/AutoGeneratedMergeFunction.c.cxxcodebuilder)
# * Struct field setter functions (ConfigGeneral/AutoGeneratedSetterFuncs.cpp.cxxcodebuilder)
# * Nginx module <-> Core headers serialization code (LocationConfig/AutoGeneratedHeaderSerialization.c.cxxcodebuilder)
#
# Options:
#
# * name - The configuration option name. Required.
# * scope - The scope that applies to this configuration. Required. One of:
# :global, :application, :location
# * context - The context in which this configuration option is valid.
# Defaults to [:main, :srv, :loc, :lif]
# * type - This configuration option's value type. Allowed types:
# :string, :integer, :uinteger, :flag, :string_array, :string_keyval,
# :path, :msec
# * default - A static default value. Set during configuration merging,
# and reported in the tracking code that generates the
# configuration manifest.
# * dynamic_default - If this option has a default, but it's dynamically inferred
# (and not a static value) then set this option to a human-readable
# description that explains how the default is dynamically inferred.
# Reported in the tracking code that generates the configuration
# manifest.
# * take - Tells Nginx how many parameters and what kind of parameter
# this configuration option takes. It should be set to a string
# such as "NGX_CONF_FLAG".
# By default this is automatically inferred from `type`: for
# example if `type` is :string then ConfigurationCommands.cxxcodebuilder.erb
# will infer that `NGX_CONF_TAKE1` should be used.
# * function - The name of the function that should be used to store the
# configuration value into the corresponding structure. This function
# is not auto-generated, so it must be the name of an existing
# function. By default, the function name is automatically inferred
# from `type`. For example if `type` is string then `function` is
# inferred to be `ngx_conf_set_str_slot`.
# If you set this to a string then you are responsible for defining
# said function in Configuration.c.
# * struct - The type of the struct that the field is contained in. Something like
# "NGX_HTTP_LOC_CONF_OFFSET" (which is also the default).
# * field - The name that should be used for the auto-generated field in
# the configuration structure. Defaults to the configuration
# name without the 'passenger_' prefix. Set this to nil if you do not
# want a structure field to be auto-generated. If the field name contains
# a dot (.e.g `upstream_config.pass_headers`) then the structure field will
# also not be auto-generated, because it is assumed to belong to an existing
# structure field.
# * post - The extra information needed by function for post-processing.
# * header - The name of the corresponding CGI header. By default CGI header
# generation code is automatically generated, using the configuration
# option's name in uppercase as the CGI header name.
# Setting this to nil, or setting `field` to a value containing a dot,
# will disable auto-generation of CGI header generation code. You are
# then responsible for writing CGI header passing code yourself in
# ContentHandler.c.
# * auto_generate_nginx_create_code - Whether configuration initialization
# code should be automatically generated. Defaults to true. If you set
# this to false then you are responsible for writing initialization code
# yourself in Configuration.c.
# * auto_generate_nginx_merge_code - Whether configuration merging
# code should be automatically generated. Defaults to true. If you set
# this to false then you are responsible for writing merging code
# yourself in Configuration.c.
# * auto_generate_nginx_tracking_code - Whether configuration hierarchy
# tracking code should be automatically generated. Defaults to true.
# If you set this to false then you are responsible for writing
# configuration tracking code yourself in Configuration.c.
# * alias_for - Set this if this configuration option is an alias for another
# option. Alias definitions must only have the `name` and `alias_for`
# fields, nothing else.
