Functions ¶
func FromDirectory ¶
FromDirectory will lookup the .rdf from the given base directory and PG eText number. If lookup speed is important, then this method is faster than using a .tar archive, at the cost of disk space.
NOTE: the directory structure must be exactly as extracted from the archive:
rdf_files/ ├─ cache/ │ └─ epub/ │ ├─ 1/ │ │ └─ pg1.rdf │ ├─ 2/ │ ...
The base dir "rdf_files" would be given with the eText id "1".
func FromTarArchive ¶
FromTarArchive will read the .rdf file from the official Project Gutenberg archive, which contain the standard PG directory structure, i.e. `cache/epub/11/pg11.rdf`.
These are currently available in two archive types:
rdf-files.tar.bz2 rdf-files.tar.zip
Reading from bz2/zip is considerably slower than just from the plain tar, so it is recommended to first extract the tar from the bz2/zip archive.
$ bzip2 -dk rdf-files.tar.bz2
If using the bz2/zip directly is required, then the `.tar.bz2` must first be wrapped in a bzip2 reader, before calling the function:
FromTarArchive(bzip2.NewReader(archiveFile), id)
