It takes as input a directory of metadata and returns either the global configuration or the package configuration as a hash. The global configuration and additional metadata about specific licenses is loaded via File::BaseDir and therefore uses XDG paths by default. This means that the configuration and supplemental license metadata is found by searching the following paths in order: =over 4 =item 1. F<$XDG_CONFIG_HOME/docknot> (F<$HOME/.config/docknot> by default) =item 2. F<$XDG_CONFIG_DIRS/docknot> (F by default) =item 3. Files included in the package. =back The global configuration file should be named F in that directory. The license metadata should be named F. Default license metadata is included with the App::DocKnot module and is used unless more specific configuration files exist. Be aware that, if such a configuration file exists, the data is not merged and only the configuration file is used. =head1 CONFIGURATION =head1 Global Configuration The global configuration file (F<$HOME/.config/docknot/config.yaml> by default) may contain the following keys: =over 4 =item archivedir Specifies the directory into which distribution tarballs are placed by the C command. The current distribution will be put in a subdirectory named after the C key in the package configuration. Older versions will be moved to the F subdirectory of I. If this is not specified, the B<-a> option to C is mandatory. =item distdir Specifies the directory into which to build and store distribution tarballs (via the C command). Subdirectories of this directory are used as working directories while the distribution is being built, and the final tarballs are stored in this directory. If this is not specified, the B<-d> options to C and C is mandatory. =item pgp_key Sign distribution tarballs generated via C with this PGP key. Equivalent to the B<-p> option to C. =item versions Path to the F<.versions> file that should be updated by C. A F<.versions> file records the versions and release dates of software packages. See L for more information. =back =head1 CLASS METHODS =over 4 =item new(ARGS) Create a new App::DocKnot::Config object. This should be used for all subsequent actions. ARGS should be a hash reference with one or more of the following keys: =over 4 =item metadata The path to the metadata for a package. Default: F relative to the current directory. =back =back =head1 INSTANCE METHODS =over 4 =item config() Load the metadata for the package and return it as a hash. The possible keys of this hash and the possible values are not yet documented. =item global_config() Load the global DocKnot configuration and return it as a hash. =back =head1 AUTHOR Russ Allbery =head1 COPYRIGHT AND LICENSE Copyright 2013-2022 Russ Allbery Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
