# 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.

# 3 - Rename to INEPT
|
||||
# 4 - Series of changes by joblack (and others?) --
|
||||
# 4.1 - quick beta fix for ADE 1.7.2 (anon)
|
||||
# 4.2 - added old 1.7.1 processing
|
||||
# 4.3 - better key search
|
||||
# 4.4 - Make it working on 64-bit Python
|
||||
# 5 - Clean up and improve 4.x changes;
|
||||
# Clean up and merge OS X support by unknown
|
||||
# 5.1 - add support for using OpenSSL on Windows in place of PyCrypto
|
||||
# 5.2 - added support for output of key to a particular file

Mobipocket Unlocker
|
||||
|
||||
How to get Drag&Drop decryption of DRM-encumbered Mobipocket eBook files.
|
||||
|
||||
You'll need the MobiDeDRM.py python script, as well as an installed version 2.4 or later of python. If you have Mac OS X Leopard (10.5) you already have a suitable version of python installed as part of Leopard.
|
||||
|
||||
Control-click the script and select "Show Package Contents" from the contextual menu. Copy the python script, which must be called "MobiDeDRM.py" into the Resources folder inside the Contents folder. (NB not into the Scripts folder - that's where the Applescript part is stored.)
|
||||
|
||||
Close the package, and you now have a drag&drop Mobipocket unlocker.
|
||||
|
||||
You can use the AppleScript ScriptEditor application to put your Mobipocket code into the script to save you having to enter it in the dialog all the time.
