mobi2lrf

kovidgoyal · 02-15-2008, 10:29 AM

After an 8-hour hackathon I'm happy to announce mobi2lrf. Converts (non DRMed) .mobi/.prc files to LRF. Supports all three levels of compression in .mobi files. Also converts metadata. Part of libprs500 v0.4.37. It's integrated into the GUI as well as a commandline tool, so using it is just as easy as using the rest of libprs500.

This is an initial release, so it likely is crawling with bugs. Thanks to darkninja for the HUFF/CDIC decompression code.

Awesome!

This is great, thanks Kovid.

Jolly good show!

Thanks!

JSWolf · 02-15-2008, 08:01 PM

I just took a look at the changelog. Very impressive!

kovidgoyal · 02-15-2008, 09:21 PM

Thanks

Ervserver · 02-15-2008, 11:20 PM

Good stuff, converted 2 books thus far. Didn't notice any bugs

lovebeta · 02-18-2008, 08:19 PM

Thanks so much. It is a god send for us with both Kindle & PRS.

I tried with one of my mobi file and it seemed that the ToC identification/generation was not working.

JSWolf · 02-18-2008, 08:23 PM

I'm going to grab a few mobi format eBooks from the library and try mobi2lrf to test it out.

kovidgoyal · 02-18-2008, 09:23 PM

Yeah the mobi files probably use special markup for the TOC. If someone can send me a few samples I can fix that.

JSWolf · 02-18-2008, 10:57 PM

I'll dig up a few Mobi files and send them your way tomorrow.

HI Kovid: I am so happy to see you getting around to MOBI PRC's... I tested the program this morning and found that it has problems with all my MOBI files (all non-DRM'ed from a single source in .NL)

Here's the error messages:

IndexError: string index out of range
Failed to perform job: Convert book:This_Means_War
Detailed traceback:

I hope you can fix it -- as I have 3GB of MOBI files I would like to convert!
Thanks for ALL your efforts!

kovidgoyal · 02-23-2008, 01:56 PM

Send me one of these files.

sindget41 · 02-24-2008, 03:08 PM

Kovid:

Thanks for the reply! Here's a random PRC file from this site in .NL that converts fanfic into PRC format for the palm. I have about 1200 of these files!
408.prc
