; === Features of the law configuration parser =====================================================

; --- The law home directory -----------------------------------------------------------------------
; The law home directory is the default location of a small number of files and directories that are
; created when working with law. Please refer to the particular configuration options below for more
; information. The law home directory defaults to "$LAW_HOME" or "$HOME/.law".

; --- Configuration file resolution order ----------------------------------------------------------
; Law configuration files are looked up in a certain order: "$LAW_CONFIG_FILE", "./law.cfg",
; "config" in the law home directory, or "etc/law/config". The config parser only reads the first
; existing file. Please also note the optional synchronization with environment variables described
; below.

; --- Inheritance and extensions -------------------------------------------------------------------
; The law configuration can inherit from or can be extended by additional configuration files. See
; the options "inherit" and "extends" in the "[core]" section of the law configuration below. The
; only difference between the two is that options defined in "inherit" do not overwrite those in the
; actual config, whereas options of "extend" do (options of extended config files are added _after_
; those in the actual config).

; --- Option referencing ---------------------------------------------------------------------------
; To avoid that some configurations are copied to other options (which is required in some cases),
; the law configuration parser supports references. The syntax for references to options in the same
; section is "&::other_option", and "&::other_section::other_option" for options in other sections.
; None is returned in case a reference cannot be resolved. The same applies to circular references.

; --- Environment variable expansion ---------------------------------------------------------------
; Configuration values that contain environment variables are automatically expanded by most getters
; of the law configuration parser, such as "get_expanded", "get_expanded_int", etc. If desired, you
; can avoid this expanion by backslash-escaping characters such as "$" or "~" to "\$" or "\~".

; --- The "None" value -----------------------------------------------------------------------------
; Getters of the law configuration parser such as "get_default", get_expanded", "get_expanded_int",
; etc., are configured to return a default value (which itself defaults to "None" (the NoneType)) in
; case an option is not existing. Sometimes it can be useful to actively declare an option as
; missing. This can be achieved by setting an option to "None" (string).

; --- Synchronization with environment variables ---------------------------------------------------
; In some scenarios it might be useful to control the value of some options via environment
; variables, for instance, when testing features or prototyping outside of an existing configuration
; file. For these cases, a synchronization mechanism is implemented that reads variables named
; "LAW__the_section__the_option" and overwrites the respective option with its value. This is
; enabled by default, but can be configured by the "sync_env" option in the "[core]" section.

; --- Synchronization with luigi configuration -----------------------------------------------------
; law is built on top of luigi and does not replace it. Therefore, another luigi-specfic
; configuration file is actually required. However, law provides a mechanism to define the luigi
; configuration right within the law configuration file. All sections starting with "luigi" plus
; underscore, e.g. "[luigi_worker]" are forwarded to luigi. Environment variable expansion is
; performed as well. This behavior is configurable by the "sync_luigi_config" option in the "[core]"
; section.


; === law configuration ============================================================================

; Description: The location of the file that contains a list of all tasks, their module, and their
; parameters for the purpose of fast autocompletion on the command line.
; Type: string
; Default: "$LAW_INDEX_FILE", "index" in the law home directory

; Default: "$LAW_SOFTWARE_DIR", "software" in the law home directory

; inherit
; Description: A comma-separated list of files that this config is inheriting, i.e., their options

; Type: string, list of strings
; Default: None

; extend
; Description: A comma-separated list of files that this config is extended by, i.e., their options
; _do_ overwrite the ones defined in _this_ file. Relative paths are resolved with respect to _this_
; file. Brace expansion, such as "myfile{1,2}.cfg" to "myfile1.cfg, myfile2.cfg" is applied.
; Type: string, list of strings
; Default: None

; sync_env
; Description: A boolean flag that decides whether the config should be synchronized with
; environment variables that have the format "LAW__the_section__the_option". When "True", the

; Other loggers can be configured conveniently by adding "my_logger: my_level" to this section. For
; instance, "law.workflow.remote: DEBUG" will set the log level of the logger defined in
; "law/workflow/remote.py" to "DEBUG". Loggers that are not part of the "law" namespace are
; supported as well.


; --- modules section ------------------------------------------------------------------------------

[modules]

; This section only accepts options without values. They are interpreted as a list of modules that
; are loaded and checked for law tasks classes when "law index" is executed. This command creates

; inefficient for directory listings (runtime linear to number of items). Brace expansion into a
; list of paths is applied.

; different timestamps for files that are known to be identical (e.g. large, identical files that
; are provided simultaneously by multiple central storage sites).
