|

For each extracted work that has not already been collated,
|
||
DLibrary will attempt to intuit its structure and create
|
||
a single ordered list of image files in the site data
|
||
directory. Each image will either be a symlink to an image
|
||
file in the extraction folder, or a single page extracted
|
||
from a PDF file.
|
||
|
||
DLibrary may fail to automatically collate a work if its
|
||
files and subdirectories are not named in a way that
|
||
indicates a clear linear ordering. In order to assist with
|
||
collation, you can provide a list of expressions specifying
|
||
where to start traversing the directory structure, what
|
||
files to include in what order, and/or what files to ignore
|
||
entirely.
|
||
|
||
An expression can be:
|
||
|
||
PATH
|
||
A single path. If this is an image, it will be appended to
|
||
the sequence of collated images for the work it belongs to;
|
||
if this is a PDF, images will be extracted from it and
|
||
concatenated to the sequence; if this is a directory, the
|
||
contents of the directory will be automatically collated
|
||
using DLibrary's default heuristics, and concatenated
|
||
to the sequence.
|
||
|
||
( PATH [PATH ...] )
|
||
A group of paths contained in parentheses. You may need to escape
|
||
the parentheses to avoid them getting parsed by your shell.
|
||
All the paths in this group will be considered together, and
|
||
automatically collated using the default heuristics, regardless
|
||
of what order the paths are provided in.
|
||
|
||
! PATH
|
||
! ( PATH [PATH ...] )
|
||
A path or group of paths to exclude from collation. You may
|
||
need to escape the !. If an excluded path appears within any
|
||
of the other specified paths, it will be skipped by the collation
|
||
heuristics.
|
||
|
||
If the only expressions provided are negations, then auto-collation
|
||
will start from the top level of the extracted work while skipping
|
||
the excluded paths.
|
||
|
||
All provided paths must be under $DLIBRARY_DIR/extract/[work id]/
|
||
for some not-yet-collated work. Paths belonging to multiple
|
||
different works can all be provided on the same command line, and
|
||
expressions will be clustered together by work id while otherwise
|
||
preserving the order they were provided in. A parenthesized group
|
||
expression must only contain paths belonging to a single work.
|
||
|
||
By default, DLibrary will attempt to collate every not-yet-collated
|
||
work (excluding "virtual" works), using the provided expressions
|
||
to assist in collation when available. The `-o` flag will direct
|
||
DLibrary to *only* collate works included in the provided expressions,
