This tool is intended to be used to create an epub version of the
standard documentation.
An epub is just a .zip file containing a bunch of XHTML files and
a few files containing metadata.
Our structure will look like:
Book Root Directory
|-- META-INF directory
| `-- container.xml
|-- mimetype
|-- content.opf
|-- toc.ncx
|-- stylesheet.css
|-- cover.xhtml
|-- toc.xhtml
|-- chapterAA.xhtml
|-- ...
`-- chapterZZ.xhtml
Begin by defining some helper functions for writing to a
file.
~~~
'FID var
:file:s:put [ @FID file:write ] s:for-each ;
:file:nl ASCII:CR @FID file:write ;
:unix:mkdir 'mkdir_-p_%s s:format unix:system ;
~~~
Create the directories needed.
~~~
'epub unix:mkdir
'epub/META-INF unix:mkdir
~~~
Then create the `mimetype` file. This is supposed to be written
without a trailing newline.
~~~
'application/epub+zip 'epub/mimetype file:spew
~~~
Then create `META-INF/container.xml`.
~~~
'epub/META-INF/container.xml file:open-for-writing !FID
'<?xml_version="1.0"?> file:s:put file:nl
'<container_version="1.0"_ file:s:put
'xmlns="urn:oasis:names:tc:opendocument:xmlns:container"> file:s:put file:nl
'<rootfiles> file:s:put file:nl
'<rootfile_full-path="content.opf"_ file:s:put
'media-type="application/oebps-package+xml"/> file:s:put file:nl
'</rootfiles> file:s:put file:nl
'</container> file:s:put file:nl
@FID file:close
~~~
Create `content.opf`. This will need to lest all of the files
that are used in the book.
Todo:
- verify the required fields and metadata
- write this to a file
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<package xmlns="http://www.idpf.org/2007/opf" unique-identifier="BookID" version="2.0">
<metadata xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:opf="http://www.idpf.org/2007/opf">
<dc:title>RETRO Forth : User Manual</dc:title>
<dc:identifier id="BookID" opf:scheme="CustomID">...bookid...</dc:identifier>
</metadata>
<manifest>
<item href="chap01.xhtml" id="chap01_page" media-type="application/xhtml+xml"/>
</manifest>
<spine toc="ncx">
<itemref idref="chap01_page" linear="yes"/>
</spine>

</package>
Assemble the pieces
~~~
'epub unix:chdir
'.. unix:chdir
~~~
zip -0Xq /tmp/book.epub mimetype
zip -Xr9Dq /tmp/book.epub *
Cleanup is the final step. Remove the temporary epub directory
~~~
'rm_-rf_epub unix:system
