Four formats a library of ebooks holds and this had no name for, so each
came back as text, as HTML or as unknown.
RTF is its opening group, after any byte-order mark and blank space.
Microsoft Reader is its signature at the front. A FictionBook is XML
whose root element is FictionBook, found by stepping over the
declaration, comments and doctype in the first four kilobytes. That walk
is over bytes rather than text, because a great many FictionBooks are
windows-1251 and would otherwise be called binary; other XML is still
HTML, as before.
A zip whose only real member is one FictionBook is zip-wrapped-fb2, the
same way a zipped PDF is zip-wrapped-pdf: handed to a converter as
FictionBook it is still a zip. A zip whose every real member is a JPEG,
PNG, GIF or WebP is cbz, once directories, ComicInfo.xml and desktop
clutter are passed over. One PDF or one readme among the pages and it is
not a comic. Only the names in the archive's directory are read, as for
every other zip.
The kind vocabulary grows by five: lit, fb2, rtf, cbz and
zip-wrapped-fb2.
The README now lists the forms it handles with an example of each, says that
where the italics sit is what decides whether they are the title or the
journal, and sets out what it refuses and why — scripture, Migne, a
contributor's biography, a note that only thanks people, a page footer.
Recipes gains "What a book leans on": one bibliography read, then the same
over a shelf, counted per citing book so a work cited forty times in one
bibliography still counts once. Every command was run — thirty converted
books gave 14,481 references, 10,536 naming a work, in about a second.
`records.md` now points at the five tools whose record shapes live in their
own pages rather than in `corpus-core`.
And pandoc escapes an underscore, so the rule of them that stands in for a
repeated author arrives as `\_\_\_\_\_` and was not being recognised.
