So, you want separate HTML pages for every, say, 300 tracks, arranged by letter ... or separate HTML pages arranged by letter, but limited to 300 tracks per page?
The only ideas I have on how to accomplish something like this is using css and/or javascript to hide most of the content of the output page until you click on a part of the menu that reveals the hidden content. I don't know of any way Mp3tag can be made to create a full interlinked web archive consiting of multiple pages; unless you separate the output by directory and name each page output based on something pulled from the tags ... but I'd have to imagine you'd still need to build the index page yourself. Unless...
Say you have your files in 27 directories, sorted #-A-Z. You write your export script so that each letter group's html file will be named "(something) X.html" where X is pulled from the first letter of the last name of the artists in that directory. You include in your export script an HTML menu at the top that links to all the different letters' HTML files. When the export is done, hopefully you have 27 different files that all link to each other.
If you don't like the alphabetical thing, perhaps base the export file name on the directory name. Shouldn't really matter. You just need to find a way to make it different but predictable for each directory.
This assumes the filename can be created dynamically from tags or $GetEnv ... I haven't tried it yet. Has anyone else done anything like this? I haven't tried many of the settings listed at
yet.
[Edit to add] I just started playing with this so I have very little idea what is possible yet, so take everything I said with a healthy dose of salt!
[Edit further to add] I do like the idea of not needing to keep the entire archive in one file. My lyrics export setting, which I've so far tried out on about 5,500 tracks with full song lyrics, results in a file that is about 10MB in size, and when fully expanded does slow down the browser a bit. People with massive collections might have problems. Plus, mine is still pretty simple ... no frames, tables, span borders, or anything visual like that. Just a plain accordionable list. It's a work in progress ... I do hope to make many more tweaks to it yet.
