NAME

App::WRT::EntryStore - model the contents of a wrt repo's entry_dir

SYNOPSIS

use App::WRT::EntryStore;
my $entries = App::WRT::EntryStore->new('./archives');

my @all = $entries->all();
my @months = $entries->all_months();
my @years = $entries->all_years();
my @days = $entries->all_days();

# all_* are wrappers for dates_by_depth():
my @days = $entries->dates_by_depth(
  3 # 1 for years, 2 for months, 3 for days
);

my @recent_days = $entries->recent_days(30);
my @recent_months = $entries->recent_months(12);
my @recent_years = $entries->recent_years(10);

# recent_* are wrappers for recent_by_depth():
my @recent_days $entries->recent_by_depth(
  3, # 1 for years, 2 for months, 3 for days
  30 # count
);

METHODS

new($class, $entry_dir)

Get a new EntryStore, using a given $entry_dir.

Finds a list of entries for the given directory, and builds data structures which can be used to index into entries by depth, property, and next/previous entry.

all()

Returns a list of all source files for the current entry archive (excepting index files, which are a special case - this part could use some work).

This was originally in App::WRT::Renderer, so there may be some pitfalls here.

dates_by_depth($depth)

Returns a sorted list of all date-like entries which are at a specified depth. Use 1 for years, 2 for months, and 3 for days.

Fairly silly, but entertaining in its perverse way. all_years(), all_months(), and all_days() are provided for convenience.

all_years(), all_months(), all_days()

Convenience wrappers for dates_by_depth().

days_for($month), months_for($year)

Convenience wrappers for extracting days or months in a given month or year.

recent_by_depth($depth, $entry_count)

Returns the $entry_count most recent dated entries at $depth (1 for year, 2 for month, 3 for day). recent_years(), recent_months(), and recent_days() are provided for convenience.

all_years(), all_months(), all_days()

Convenience wrappers for recent_by_depth().

generate_date_hashes()

Store hashes which map dated entries to their previous and next entries at the same depth in the tree. That is, something like:

%prev_dates = {
  '2014'     => '2013',
  '2014/1'   => '2013/12'
  '2014/1/1' => '2013/12/30',
  ...
}

%next_dates = {
  '2013'       => '2014',
  '2013/12'    => '2014/1',
  '2013/12/30' => '2014/1/1',
  ...
}
parent($entry)

Return an entry's parent, or undef if it's at the top level.

children($entry)

Return an entry's (immediate) children.

previous($entry)

Return the previous entry at the same depth for the given entry.

next($entry)

Return the next entry at the same depth for the given entry.

by_prop($property)

Return an array of any entries for the given property.

props_for($entry)

Return an array of any properties for the given entry.

has_prop($entry, $prop)

Return 1 if the given entry has the given property.

all_props()

Return an array of all properties.

is_extant($entry)

Check if a given entry exists.

is_dir($entry)

Check if an entry is a directory.

is_file($entry)

Check if an entry is a flatfile.

has_index($entry)

Check if an entry contains an index file.

TODO: Should this care about the pathological(?) case where index is a directory?

basename($entry)

Get a base name (i.e., filename without path) for a given entry.
