Convert ‘epub’ Files to Text

Description

Convert ‘epub’ Files to Text

The ‘epub’ file format is really just a structured ‘ZIP’ archive with metadata, graphics and (usually) ‘HTML’ text. Tools are provided to turn an ‘epub’ file into a tidy data frame.

What’s Inside The Tin

The following functions are implemented:

• epub_to_text: Convert an epub file into a data frame of plaintext chapters

NOTE

There are edge cases I’ve totally not covered yet. Feel free to jump in and make this a real, useful package!

TODO

• Refactor so there aren’t so many heavy dependencies
• [ ] Try to get hgr on CRAN so it’s not a GH dep Moved the cleaner code into here
• Better docs
• Embed some epubs for examples and tests
• Setup Travis, Appveyor, code coverage

Installation

devtools::install_github("hrbrmstr/pubcrawl")

Usage

library(pubcrawl)
library(tidyverse)
