I would like to submit three recent scripts, which I wrote to deal with ebook difficulties on my Victor Reader ( a "talking book" reader with text-to-voice capability).
heading-numbers.awk makes a HTML page more readable in my Victor Reader. A HTML page works as well as an ePub or DAISY book, but often does not have heading numbers. The absence of heading numbers makes it difficult to navigate a very long page via hearing, because you don't know where you are in the file. This awk program puts multilevel heading numbers at the start of every heading. The victor Reader can be set to jump from one heading to another at any level from 1 to 6, allowing me to quickly zero in on the part of the page I want. I wrote the other two scripts to troubleshoot a problem where my Victor Reader would not jump to some of the headings in the ePub, epubcheck.sh runs the W3C ePub Validator. It is easy to run the validator correctly but the script allows me to park the package in a subdirectory of the bin directory and run the validator with a simple command that is on my PATH. The validator showed that my problem ebook was a valid ePub 2.0.1 file. html-headings.awk <https://mail.google.com/mail/u/0?ui=2&ik=e676b26630&attid=0.2&permmsgid=msg-a:r2437192347788727639&view=att&disp=safe&realattid=f_lpu7k5tg1> extracts headings from an HTML or ePub file. I unzipped the ePub file to and empty directory and rand the command html-headings.awk <https://mail.google.com/mail/u/0?ui=2&ik=e676b26630&attid=0.2&permmsgid=msg-a:r2437192347788727639&view=att&disp=safe&realattid=f_lpu7k5tg1> *.html > all-headings.txt The command produced a list of 272 headings, one to a line. I looked at the headings and CSS file, could not see a reason for the behaviour and submitted a report to the manufacturer. Both AWK programs use a feature of AWK to make the job easy: the record separators (RS and ORS, normally both are line-ends) are arbitrary, Changing the record separators to '<' places every tag at the beginning of a line, making it easy to identify the tags you want to work with.
