A collection of tools Standard Ebooks uses to produce its ebooks, including basic setup of ebooks, text processing, and build tools.
Several dependencies must be installed before you can use these tools. On Ubuntu 16.04, you can install everything with:
sudo apt install python3-pip xsltproc libxml2-utils xmlstarlet libxml-xpath-perl recode html-xml-utils python3-cssselect python3-regex python3-pip librsvg2-bin libimage-exiftool-perl python3-lxml zip epubcheck calibre sudo pip3 install pyhyphen roman titlecase beautifulsoup4 smartypants sudo python3 -c "exec(\"from hyphen import dictools\\ndictools.install('en_GB')\\ndictools.install('en_US')\")" #Install required fonts mkdir -p ~/.fonts/ wget -O ~/.fonts/LeagueSpartan-Bold.otf "https://github.com/theleagueof/league-spartan/blob/master/LeagueSpartan-Bold.otf?raw=true" wget -O ~/.fonts/OFLGoudyStM.otf "https://github.com/theleagueof/sorts-mill-goudy/blob/master/OFLGoudyStM.otf?raw=true" wget -O ~/.fonts/OFLGoudyStM-Italic.otf "https://github.com/theleagueof/sorts-mill-goudy/blob/master/OFLGoudyStM-Italic.otf?raw=true" sudo fc-cache -fv

Create a skeleton of a new Standard Ebook.
Convert a decimal number to a Roman numeral.
Convert epub-friendly endnotes to Kindle-friendly popup endnotes.
Find words with mismatched diacritics in Standard Ebook source directories. For example, 'cafe' in one file and 'café' in another.

A macro for calling Vim to interactively search and replace a regex on a list of files.

Apply some scriptable semantics rules from the Standard Ebooks semantics manual to a Standard Ebook source directory.
Simplify some HTML and CSS to be more compatible with crappier reading systems (ADE I'm looking at you...)
Split an XHTML file into many files at all instances of
<!--se:split-->, and include a header template for each file.
Convert a string to titlecase.
Flatten ToC to be at most 2 levels deep for Kindle compatibility. Generally only used by the
buildscript and not called independently.
Apply some scriptable typography rules from the Standard Ebooks typography manual to a Standard Ebook source directory.
Display Unicode code points, descriptions, and links to more details for each character in a string. Useful for differentiating between different flavors of spaces, dashes, and invisible characters like word joiners.
Change the ASIN of a mobi/azw3 file.
Count the number of words in an HTML file and optionally categorize by length.
Check all author directories in the current or specified directory to see if there are changes that need to be committed.
What a Standard Ebooks source directory looks like
Many of these tools act on Standard Ebooks source directories. Such directories have a consistent minimal structure:
. |-images/ |--cover.jpg |--cover.source.jpg |--cover.svg |--titlepage.svg |-src/ |--epub/ |---css/ |----core.css |----local.css |---images/ |----cover.svg |----titlepage.svg |---text/ |---content.opf |---onix.xml |---toc.xhtml |--META-INF/ |---container.xml |--mimetype
./images/ contains source images for the cover and titlepages, as well as ebook-specific source images. Source images should be in their maximum available resolution, then compressed and placed in
./src/epub/images/ for distribution.
./src/epub/ contains the actual epub files.
