# 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.
|
|
|
# 0.16 - convert to use openssl DES (very very fast) or pure python DES if openssl's libcrypto is not available
|
|
|
# 0.17 - added support for pycrypto's DES as well
|
|
|
# 0.18 - on Windows try PyCrypto first and OpenSSL next
|
|
|
# 0.19 - Modify the interface to allow use of import
|
|
|
# 0.20 - modify to allow use inside new interface for calibre plugins
|
|
|
# 0.21 - Support eReader (drm) version 11.
|
|
|
# - Don't reject dictionary format.
|
|
|
# - Ignore sidebars for dictionaries (different format?)
|
|
|
# 0.22 - Unicode and plugin support, different image folders for PMLZ and source
|
|
|
# 0.23 - moved unicode_argv call inside main for Windows DeDRM compatibility
|
|
|
# 1.00 - Added Python 3 compatibility for calibre 5.0
|
|
|
# 1.01 - Bugfixes for standalone version.
|
|
|
# 1.02 - Remove OpenSSL support; only use PyCryptodome
|
