0.4.0

Added

• date range selection: cal-like option -3 to select the current month together with the preceding and following one (contributed by Fabio Soares @fabiosoaresv)
• if exactly one sanctorale data file is specified and its YAML front matter references a parent calendar (key extends), the file is loaded with its complete graph of parents
• option --[no-]load-parents to explicitly enable/disable loading of parent calendars
• basic support for remote calendars: the --calendar= option now accepts also a calendar API URL like --calendar=http://calapi.inadiutorium.cz/api/v0/en/calendars/general-la, the referenced API is expected to be compatible with Liturgical Calendar API v0
• calendar listing (--calendars) marks default calendar as such
• calendar listing lists each calendar's parents
• option --verbose
• condensed view (--format=condensed), intended for use cases like printing current day in a window manager toolbar and the like
• option --to-sunday= to configure which temporale solemnities should be transferred to Sunday (e.g. --to-sunday=epiphany)
• option --temporale-extension= to activate temporale extension (supported values are temporale extension class names, e.g. --temporale-extension=ChristEternalPriest)
• any class in the Calrom::Formatter module is considered formatter and its lowercased name can be used as value for the --format= option - custom formatters can be added by defining new classes in the namespace
• options --day-filter= and --celebration-filter= for filtering days and celebrations by a Ruby expression
• environment variable CALROM_CURRENT_DATE can be used to override current date (intended mainly for testing)

Changed

• automated locale selection based on sanctorale data file relies solely on the locale key of the file's YAML front matter (previously it relied on a file naming convention)
• option --calendar= expands tilde in path (if it isn't expanded by shell, as is the case e.g. in configuration files)
• when displaying just a single day, highlighting of the current day is disabled by default (i.e. if the day being displayed is current day, it won't be highlighted as such)
• list view (--list): rank is not printed for ferials and Sundays
• overview view always arranges the displayed months in multiple columns, just like cal (previously date ranges spanning less than three months were printed in a single column)
• date range specification: support for dates with year higher than 9999 (e.g. 10000-01-01)

Fixed

• crash on invalid value of --locale
• list view: when printing a date range between the same months of different years (e.g. 2000-01-xx .. 2001-01-xx), year was not printed in month headings
