Anemone DAISY maker

Anemone is a Python 3 script to put together a DAISY digital talking book, from HTML text, MP3 audio recordings and time index data.

Anemone produces DAISY 2.02 files by default, or DAISY 3 (i.e. ANSI/NISO Z39.86) if an option is set. It can produce four different types of digital talking book:

  1. Full audio with basic Navigation Control Centre only: this requires a list of MP3 or WAV files for the audio, one per section, and the title of each section can be placed either in a separate text file or in the filename of the audio file.
  2. Full audio with full text: this requires MP3 or WAV files for the audio, corresponding XHTML files for the text, and corresponding JSON files for the timing synchronisation. Each JSON file is expected to contain a list called "markers" whose items contain "id" (or "paragraphId" or anything else ending id) and "time" (or "startTime" or anything else ending time), which can be in seconds, minutes:seconds or hours:minutes:seconds (fractions of a second are allowed in each case). The IDs in these JSON files should have corresponding attributes in the XHTML, by default data-pid but this can be changed with an option.
  3. Text with no audio: this requires just XHTML files, and extracts all text with a specified attribute (data-pid by default)
  4. Text with some audio: this is a combination of the above two methods, and you'll need to specify skip in the JSON file list for the chapters that do not yet have recorded audio

All files are placed on the command line (or in parameters if you're using Anemone as a module), and Anemone assumes the correspondences are ordered. So for example if MP3, HTML and JSON files are given, Anemone assumes the first-listed MP3 file corresponds with the first-listed HTML file and the first-listed JSON file, and so on for the second, third, etc. With most sensible file naming schemes, you should be able to use shell wildcards like * when passing the files to Anemone.

You may also set the name of an output file ending zip; the suffix is common.

The title, publisher, language etc of the book should be set via options: run the program with --help or see below.

Download or use pip install anemone-daisy-maker or pipx run anemone-daisy-maker

History on GitHub

The daisy anemone is a sea creature on the rocky Western shores of Britain and Ireland; the Dorset Wildlife Trust says it's "usually found in deep pools or hiding in holes or crevices, or buried in the sediment with only tentacles displayed". Similarly this script has no interactive user interface; it hides away on the command line, or as a library module for your Python program.

Options for Anemone 1.6

the ISO 639 language code of the publication (defaults to en for English)
the title of the publication
the URL or ISBN of the publication
the creator name, if known
the publisher name, if known
the name of the reader who voiced the recordings, if known
the publication date as YYYY-MM-DD, default is current date
the attribute used in the HTML to indicate a segment number corresponding to a JSON time marker entry, default is data-pid
the attribute used in the HTML to indicate a page number, default is data-no
the attribute used in the HTML to indicate an absolute image URL to be included in the DAISY file, default is data-zoom
if images etc have already been fetched from URLs, ask the server if they should be fetched again (use If- Modified-Since)
path name for the URL-fetching cache (default 'cache' in the current directory; set to empty string if you don't want to save anything); when using anemone as a module, you can instead pass in a requests_cache session object if you want that to do it instead, although the delay option is ignored when you do this
if images etc have already been fetched from URLs, fetch them again without If-Modified-Since
minimum number of seconds between URL fetches (default none)
User-Agent string to send for URL fetches
Use the Daisy 3 format (ANSI/NISO Z39.86) instead of the Daisy 2.02 format. This may require more modern reader software, and Anemone does not yet support Daisy 3 only features like tables.
re-code the MP3 files to ensure they are constant bitrate and more likely to work with the more limited DAISY-reading programs like FSReader 3 (this option requires LAME)
Allow jumps in heading levels e.g. h1 to h3 if the input HTML does it. This seems OK on modern readers but might cause older reading devices to give an error. Without this option, headings are promoted where necessary to ensure only incremental depth increase.
When generating Daisy 2, avoid using a heading in the navigation control centre when there isn't a heading in the text. This currently applies when spans with verse numbering are detected. Turning on this option will make the DAISY more conformant to the specification, but some readers (EasyReader 10, Thorium) won't show these headings in the navigation in Daisy 2 (but will show them anyway in Daisy 3, so this option is applied automatically in Daisy 3). On the other hand, when using verse-numbered spans without this option, EasyReader 10 may not show any text at all in Daisy 2 (Anemone will warn if this is the case). This setting cannot stop EasyReader promoting all verses to headings (losing paragraph formatting) in Daisy 3, which is the least bad option if you want these navigation points to work.
Combine multiple books into one, for saving media on CD-based DAISY players that cannot handle more than one book. The format of this option is book1/N1,book2/N2,etc where book1 is the book title and N1 is the number of MP3 files to group into it (or if passing the option into the anemone module, you may use a list of tuples). All headings are pushed down one level and book name headings are added at top level.
Comma-separated list of titles to use for chapters that don't have titles, e.g. 'Chapter N' in the language of the book (this can help for search-based navigation). If passing this option into the anemone module, you may use a list instead of a comma- separated string, which might be useful if there are commas in some chapter titles.
Heading level to use for chapters that don't have titles
Treat warnings as errors
Don't actually output DAISY, just check the input and parameters
