Hi,

Please some help for a newbe

I have installed python 2.7.1
put my PRC file (same as mobi file right ?)into the same folder as mobiunpack.py and run the mobiunpack.py.

do I have to use the cmd.exe to run this script ?

how to ?

Hi,

If you are on windows, I assume you have downloaded and installed ActiveState's ActivePython 2.X for 32 bit as was recommended in this very thread.

Next, you should know there is a gui version of the program (i.e no command line needed) available called MobiUnpack.pyw which actually runs the mobiunpack.py script for you (which is hidden away in the lib directory beside MobiUnpack.pyw).
To run the gui version, simply double-click on MobiUnpack.pyw


To run the command line version:
Yes, you need to run cmd.exe.

But first thing is to create a new folder to hold the contents of the unpack operation. So create a new folder right beside mobiunpack.py and your .mobi file.

Then run cmd.exe and cd to where mobiunpack.py exists

Then run the following command at the prompt:

python mobiunpack.py YOURMOBIFILEHERE.mobi YOURNEWOUTPUTFOLDER

That should unpack any non-drm Mobi file into its pieces. If you look in YOURNEWOUTPUTFOLDER afterwards you will see the .html images/ .op files.

If you run into trouble simply pm KevinH here and I can try to help.

Hi I tried the .pyw but it did nothing

I tried the py in cmd and got an error, the file could not be found :
[/URL]

however, I'm sure, ther is no mistake in the name of the file.

Hi,

What happened exactly (what error message) when you double-clicked on MobiUnpack.pyw? If you have properly installed Python on your machine, double-clicking on the MobiUnpack.pyw file should start up a gui window. To test if that would be the case, right click on the MobiUnpack.pyw file and make sure it is properly associated with the pythonw.exe executable that is part of Python 2.X. You probably have not added the Python executable path to your System PATH environment variable or you are using Python 2.7 from python.org and not the ActiveState version that was recommended.

As for your command line errors, if your file exists, then your issue is one of paths. The mobiunpack.py program looked right beside itself to find the fra-eng.mobi book and could not find it (that is why there is an error message).

To make things a little easier triple check that you have copied mobiunpack.py and your fra-eng.mobi to the exact same folder and that inside that folder (right beside your fra-eng.mobi book and mobiunpack.py), you create a new empty folder called "book".

Then run cmd.exe and cd to the folder where mobiunpack.py, your "book" folder and fra-eng.mobi are.

The type the following command:

python.exe mobiunpack.py fra-eng.mobi book

Once complete, you will find the pieces inside the "book" folder.
If not, then there is probably something wrong with how you have installed Python.

[discusaigon]

the probleme is I don't have any error message when I try to use the pyw

nothing just happens

I may have a problem with my python installation

[discusaigon]

It is bizar ...

I tried an old script I had in pyw (ineptpdf.pyw) and it worked well so python is well installed on my computer.

I simplified the name of my file to avoid mistakes and still have the same errors with the script :

[/URL]

as you can see ther is no mistake in the folder or file name

[quocsan]

Please change directory to I:\py then run the script or put "\py" before the ebook name (such as \py\dico.mobi.
It showed errors because there is no "dico.mobi" in the current directory (I:\)

[discusaigon]

thanks !

changing direcotry was the trick !

I learned how to use the cd\

and it works well now.

I tried with the first script and it was quick.

Now with the second, it's slower but I understand it might be normal as it has to manage images.

Thanks for your improvement.
Now the big challenge should be mobi dictionary.

My next big challenge is to handle multiple authors correctly, which requires big internal changes.

But feel free to have a go at handling dictionaries yourself...

It took me several weeks of reverse engineering and a few days of coding, but here is finally the first mobiunpack version supporting dictionaries!

I've made some shortcuts and omitted features not necessary for the dictionaries I'm interested in (e.g. unicode support, the old deprecated inflection format), so the script might not work for the dictionary you want to unpack, but feel free to improve the code

A couple of other fixes and enhancements are also included, most notable some speed optimizations. A huge dictionary is now unpacked within minutes instead of hours by using temporary files.

Have fun!

My god, I could not believe where I am now. You make my dream come true.
unpacking speed, inflection, unicode, all these were pain, now no more harassing!

Thanks a lot,

and its unpacking speed is far faster than ever.

Hi,

I've created a new version 0.27 with the following changes:

• NEW: Extract and save source zip files included by kindlegen as kindlegensrc.zip.
• FIXED: idx:entry attribute "scriptable" must be present to create entry length tags.
• FIXED: Don't save non-image sections as images.

mobiunpack_0.27.zip

To ease development I've also pushed my git repository for the mobipocket script to github. Feel free to fork it if you want to improve the script:
