eReader PDB2PML - eReaderPDB2PML_vXX_plugin.zip
|
||||
|
||||
All credit given to The Dark Reverser for the original standalone script. I had the much easier job of converting it to a Calibre plugin.
|
||||
|
||||
This plugin is meant to convert secure Ereader files (PDB) to unsecured PMLZ files. Calibre can then convert it to whatever format you desire. It is meant to function without having to install any dependencies... other than having Calibre installed, of course. I've included the psyco libraries (compiled for each platform) for speed. If your system can use them, great! Otherwise, they won't be used and things will just work slower.
|
||||
|
||||
Installation:
|
||||
Go to Calibre's Preferences page... click on the Plugins button. Use the file dialog button to select the plugin's zip file (eReaderPDB2PML_vXX_plugin.zip) and click the 'Add' button. You're done.
|
||||
|
||||
Configuration:
|
||||
Highlight the plugin (eReader PDB 2 PML under the "File type plugins" category) and click the "Customize Plugin" button on Calibre's Preferences->Plugins page. Enter your name and last 8 digits of the credit card number separated by a comma: Your Name,12341234
|
||||
|
||||
If you've purchased books with more than one credit card, separate the info with a colon: Your Name,12341234:Other Name,23452345 (NOTE: Do NOT put quotes around your name like you do with the original script!!)
|
||||
|
||||
Troubleshooting:
|
||||
If you find that it's not working for you (imported pdb's are not converted to pmlz format), you can save a lot of time and trouble by trying to add the pdb to Calibre with the command line tools. This will print out a lot of helpful debugging info that can be copied into any online help requests. I'm going to ask you to do it first, anyway, so you might
|
||||
as well get used to it. ;)
|
||||
|
||||
Open a command prompt (terminal) and change to the directory where the ebook you're trying to import resides. Then type the command "calibredb add your_ebook.pdb". Don't type the quotes and obviously change the 'your_ebook.pdb' to whatever the filename of your book is. Copy the resulting output and paste it into any online help request you make.
|
||||
|
||||
** Note: the Mac version of Calibre doesn't install the command line tools by default. If you go to the 'Preferences' page and click on the miscellaneous button, you'll see the option to install the command line tools.

|

# Changelog
|
||||
#
|
||||
# Based on ereader2html version 0.08 plus some later small fixes
|
||||
#
|
||||
# 0.01 - Initial version
|
||||
# 0.02 - Support more eReader files. Support bold text and links. Fix PML decoder parsing bug.
|
||||
# 0.03 - Fix incorrect variable usage at one place.
|
||||
# 0.03b - enhancement by DeBockle (version 259 support)
|
||||
# Custom version 0.03 - no change to eReader support, only usability changes
|
||||
# - start of pep-8 indentation (spaces not tab), fix trailing blanks
|
||||
# - version variable, only one place to change
|
||||
# - added main routine, now callable as a library/module,
|
||||
# means tools can add optional support for ereader2html
|
||||
# - outdir is no longer a mandatory parameter (defaults based on input name if missing)
|
||||
# - time taken output to stdout
|
||||
# - Psyco support - reduces runtime by a factor of (over) 3!
|
||||
# E.g. (~600Kb file) 90 secs down to 24 secs
|
||||
# - newstyle classes
|
||||
# - changed map call to list comprehension
|
||||
# may not work with python 2.3
|
||||
# without Psyco this reduces runtime to 90%
|
||||
# E.g. 90 secs down to 77 secs
|
||||
# Psyco with map calls takes longer, do not run with map in Psyco JIT!
|
||||
# - izip calls used instead of zip (if available), further reduction
|
||||
# in run time (factor of 4.5).
|
||||
# E.g. (~600Kb file) 90 secs down to 20 secs
|
||||
# - Python 2.6+ support, avoid DeprecationWarning with sha/sha1
|
||||
# 0.04 - Footnote support, PML output, correct charset in html, support more PML tags
|
||||
# - Feature change, dump out PML file
|
||||
# - Added supprt for footnote tags. NOTE footnote ids appear to be bad (not usable)
|
||||
# in some pdb files :-( due to the same id being used multiple times
|
||||
# - Added correct charset encoding (pml is based on cp1252)
|
||||
# - Added logging support.
|
||||
# 0.05 - Improved type 272 support for sidebars, links, chapters, metainfo, etc
|
||||
# 0.06 - Merge of 0.04 and 0.05. Improved HTML output
|
||||
# Placed images in subfolder, so that it's possible to just
|
||||
# drop the book.pml file onto DropBook to make an unencrypted
|
||||
# copy of the eReader file.
|
||||
# Using that with Calibre works a lot better than the HTML
|
||||
# conversion in this code.
|
||||
# 0.07 - Further Improved type 272 support for sidebars with all earlier fixes
|
||||
# 0.08 - fixed typos, removed extraneous things
|
||||
# 0.09 - fixed typos in first_pages to first_page to again support older formats
|
||||
# 0.10 - minor cleanups
|
||||
# 0.11 - fixups for using correct xml for footnotes and sidebars for use with Dropbook
|
||||
# 0.12 - Fix added to prevent lowercasing of image names when the pml code itself uses a different case in the link name.
|
||||
# 0.13 - change to unbuffered stdout for use with gui front ends
|
||||
# 0.14 - contributed enhancement to support --make-pmlz switch
|
||||
# 0.15 - enabled high-ascii to pml character encoding. DropBook now works on Mac.
