Tested, works fine :)

Perfect! Now everyone can have the exact indent they want. :)
Great collaborative work geek1011 and GeoffR, karma to you both!

@geek1011 thank you very much for the patches. They works very fine on our readers (H20 2nd Edition, GloHD and Glo). :thumbsup:

Spoiler:

@GeoffR your modified version works very well. I use factor 10 on my H2O 2nd edition and factor 8 on my husband's GloHD and Glo respectively. Thank you very much. :thumbsup:

Do you want the patch files updated to this?

I don't know, I'm not using this firmware myself, I just posted it as an example. Others will probably have a better idea about what replacement value is best to use as the default.

I'm not sure I'm entitled to a say but I'd vote for GeoffR's variation becoming the standard version of the patch because of it's more granular customisation. This is assuming you think it will be maintainable across new firmware upgrades.

I'm more asking about if he wants it included as-is. It's not much harder to maintain, as I just need to check the value at the beginning of the function when I update it.

While patching my Kobo Touch (A), I received this Log:

        validating patch file

        --> i4: internal error while validating `Un-Force user font-family in KePubs` (you should report this as a bug)

The patch in question has this settings:

Code:

Un-Force user font-family in KePubs:

  - Enabled: yes

  - Description: |

      The KePub reader uses a very heavy-handed method of setting the font selected

      by the user, overriding all fonts set by the publisher in the book unless

      "Publisher Default" is selected.

      This patch lets the font-family set by the publisher in the KePub stylesheet

      override the font-family selected by the reader from the device in some

      cases, which allows a mix of user-selected and publisher-selected fonts.

      Alternatives 1-3 give increasing preference to the publisher-selected fonts.

  - FindBaseAddressString: "* { font-family: %1 !important; }\n"

    #

    # Alternative 1:

    #     * { font-family: %1 !important; }\n

    # --> div,p{font-family:%1!important; }\n

  - ReplaceString:

    #  Offset: 0

    #  Find: "* { font-family: %1 !important; }\n"

    #  Replace: "div,p{font-family:%1!important; }\n"

    #  MustMatchLength: yes

    #

    # Alternative 2: (Similar to ePub default)

    #     * { font-family: %1 !important; }\n

    # --> body,p{font-family:%1!important;}\n

  - ReplaceString:

      Offset: 0

      Find: "* { font-family: %1 !important; }\n"

      Replace: "body,p{font-family:%1!important;}\n"

      MustMatchLength: yes

    #

    # Alternative 3: (similar to ePub with `Un-force font-family override p tags`)

    #     * { font-family: %1 !important; }\n

Is the error caused by me?

Yes, you unleashed wrong lines.

Code:

    #     * { font-family: %1 !important; }\n

    # --> div,p{font-family:%1!important; }\n

Yes, of course!:smack:
Thank you for the quick reply!
Suggestion for a further patch: remove tomatoes in front of the eyes.

Can anyone get "ePub fixed/adjustable top/bottom margins" to work? I want to make the top and bottom margins adjustable so I leave everything commented but all I got is this. The margins are fixed.

This patch worked on GeoffR's version so I'm not sure what I did wrong.

What exactly do you mean by GeoffR's version? He updated the patch himself: https://github.com/geek1011/kobopatc...818727465c1d11.

I mean back then when GeoffR still made his version of patch. Didn't realise that was a year ago :rolleyes:

From your screenshot I guess you have enabled the Reduce top/bottom page spacer patch? (in nickel.yaml) If so then you should also edit the last line of the ePub fixed/adjustable top/bottom margins patch to reflect the new size of the built-in margins:

Spoiler:

Edit: Two more things to check:
* Check that the book really is an ePub. The adjustable top/bottom margins stopped working for KePubs in firmware version 4.12.12111.
* Check that the book doesn't have an Adobe XPGT stylesheet: If it does then use the Modify Epub plugin in Calibre to remove it.

Feeling really stupid, but I can't seem to get the update to run. New to Kobo, but I've done the following per the instructions:
1. Upgraded to 4.15.12920
2. Downloaded patched version and unzipped
3. Downloaded original 4.15.12920 firmware
4. Copied original 4.15.12920 zip file to SRC folder in unzipped patched version
5. Copied patched folder to root directory of kobo
6. Unmounted

I've read elsewhere that the update should start automatically, but that is not happening.
