I’ve been programming. First a fast replacement for displaying metadata of an EPUB-file:
\n
\n$ epub-meta -v 1632.epub File: 1632.epub
\nTitle: 1632

\n<\/code>
\nIt has commandline-switches to selectively choose which metadata should be displayed. And it does it very fast, 3ms on my system, as opposed to 670ms ebook-meta<\/code> from Calibre needs. However, it can only display the metadata, not change it. For changing metadata, you still need ebook-meta<\/code>. <\/p>\n

Having the ability to display metadata fast, made it possible to rename EPUB-files. Initially, I had the idea to do that in C too, but working with strings is actually quite tedious in C, so I decided on perl. So there’s now also a program called epub-rename<\/code>, which renames EPUB-files according to it’s metadata in the format Author - Series SeriesIndex - Title<\/code>. Moreover, it also has, trough ebook-meta<\/code>, the ability to fix certain issues in metadata-tags. Namely change inverted Title\/Author tags, fix Author-Tags which are in the wrong(!) Last, First<\/em>-Format, and some more. <\/p>\n

Well, here’s the “–help”
\n$ epub-rename --help
\nUsage:\n [options] [directory ...]<\/p>\n

Options:
\n -c|--compat
\n -f|--fix
\n -h|--help
\n -t|--title
\n -r|--rename
\n -x|--exchange
\n -v|--verbose<\/p>\n

Options:
\n -c|--compat
\n Use ebook-meta from calibre instead of epub-meta. Much slower.<\/p>\n

-t|--title
\n Fix title. This means the tag gets sanitized, as it would if
\n destined for a filename, and then written back to the metadata.
\n Uses ebook-meta.<\/p>\n

-f|--fix
\n Fix all tags: author, title, and in some cases date. Uses
\n ebook-meta and touches every file, even those that don't need
\n fixing. Slow.<\/p>\n

-h|--help
\n Print a brief help message and exit.<\/p>\n

-r|--rename
\n rename files to the pattern \"Author - Series SeriesIndex -
\n Title\"<\/p>\n

-x|--exchange
\n changes title for author-tag and vice versa. For all those files
\n that have the author in the title-field and the title in the
\n author- field. Uses ebook-meta, thus is slow.<\/p>\n

-v|--verbose
\n Show how all files would be renamed, not just those really
\n renamed.\n<\/this><\/code><\/p>\n

And here’s the program itself: epub-meta-0.2.tar.gz<\/a>. MIT-Licensed. Enjoy. <\/p>\n

If you don’t like the spaces, punctuation and UTF-8-characters in the output filenames, I’d recommend another program of mine: bicapitalize<\/a>. <\/p>\n","protected":false},"excerpt":{"rendered":"
