Unofficial Patches for 4.38.23552

[John F]

I need some help with the patches please. I'm trying to set the "My 10 line spacing values" by modying src\libnickel.so.1.0.0.yaml. But they don't seem to be applied.

Attached is the log. The thing that stands out to me in the log is:

        applying overrides
            override My 10 line spacing values -> enabled:false

but this is what I have in libnickel.so.1.0.0.yaml.

My 10 line spacing values:
  - Enabled: yes
  - PatchGroup: Line spacing values alternatives
  - Description: |
      This patch changes the values on the line spacing adjustment slider,
      reducing the number of spacing options from 15 to 10, but allowing
      much narrower spacing values to be set.
    # Bypass code-constructed values 1.0, 1.2, 1.5, 2.0, 3.0
    # These are all the appends not loaded using adr.
  - BaseAddress:  {Sym: "ReadingSettings::lineHeightScalars() const", Rel: 84} # first append
  - ReplaceBytes: {Offset:   0, FindInstBLX: {SymPLT: "QList<double>::append(double const&)"}, ReplaceInstNOP: true}
  - ReplaceBytes: {Offset:  86, FindInstBLX: {SymPLT: "QList<double>::append(double const&)"}, ReplaceInstNOP: true}
  - ReplaceBytes: {Offset: 128, FindInstBLX: {SymPLT: "QList<double>::append(double const&)"}, ReplaceInstNOP: true}
  - ReplaceBytes: {Offset: 188, FindInstBLX: {SymPLT: "QList<double>::append(double const&)"}, ReplaceInstNOP: true}
  - ReplaceBytes: {Offset: 290, FindInstBLX: {SymPLT: "QList<double>::append(double const&)"}, ReplaceInstNOP: true}
    # 10 values for replacement, change these replace_float values to suit:
    # Find the prologue for the values + first subtraction (has been unique in
    # every version so far, and is near impossible to change and fail silently):
  - FindBaseAddressHex: CDCC CCCC CCCC F03F 1F85
  - ReplaceFloat: {Offset: 0x00,  Find: 1.05, Replace: 0.8}
  - ReplaceFloat: {Offset: 0x08,  Find: 1.07, Replace: 0.85}
  - ReplaceFloat: {Offset: 0x10,  Find: 1.1,  Replace: 0.875}
  - ReplaceFloat: {Offset: 0x18,  Find: 1.35, Replace: 0.9}
  - ReplaceFloat: {Offset: 0x20,  Find: 1.7,  Replace: 0.925}
  - ReplaceFloat: {Offset: 0x28,  Find: 1.8,  Replace: 0.95}
  - ReplaceFloat: {Offset: 0x30,  Find: 2.2,  Replace: 0.975}
  - ReplaceFloat: {Offset: 0x38,  Find: 2.4,  Replace: 1.0}
  - ReplaceFloat: {Offset: 0x40,  Find: 2.6,  Replace: 1.05}
  - ReplaceFloat: {Offset: 0x48,  Find: 2.8,  Replace: 1.1}

I haven't done any patching in a long time, so not sure what is going on.

Thank you for the help.

Edit the kobopatch.yaml file.

Thank you.

Do I just change it to yes and make the detailed changes in the other file? It looks like it works, but my custom font sizes don't seem to be taking affect.

Just edit this file without affecting other files. As understand, in kobopatch.yaml Jon added all the currently existing patches. Or almost everything.
Indicate in it: yes or no.

It is everything in kobopatch.yaml. You do the yes/no in there and any edits to the patches in the appropriate .yaml in the src directory.

My 10 line spacing values is for the line spacing slider.

Might you want Custom font sizes which is in libnickel.so.1.0.0.yaml?

I had yes for both of those, and edited both of those in libnickel.so.1.0.0.yaml.

If I decide to update the firmware, I'll have to redo my edits to My 10 line spacing values.

In the ZIP file attached to the first post, the kobopatch.yaml file says, on line 3:

version: 4.38.2552

I assume that this should actually be:

version: 4.38.23552

but I'm unsure whether it is actually used anywhere or makes any difference to anything.

That is a mistake. But it doesn't matter because the in: line with the name of the source file is correct.

I'm trying to patch my Kobo Libra 2 running firmware 4.38.23552.

My favorite patch, "Both page turn buttons go to next," isn't working. Yes, I know the description line for this patch in libnickel.so.1.0.0.yaml says "Make both page turn buttons on the Forma go next in the reader" -- but it's always worked before for the Libra 2, as well.

This is the error message from kobopatch.bat:

APPLY `Both page turn buttons go next`

    Error: could not apply patch "Both page turn buttons go next": line 820: inst 3: ReplaceBytes: expand FindInstB=kobopatch.FlexAbsOffset{Offset:(*int32)(nil), Sym:(*string)(nil), SymPLT:(*string)(nil), SymPLTTail:(*string)(0x18d2dd8), Inline:false, Rel:(*int32)(nil)}: ResolveSymPLTTail("ReadingView::prevPageWithTimer()") = &patchlib.dynsym{Name:"_ZN11ReadingView17prevPageWithTimerEv", Offset:0xf66940, Index:0x7112, Type:elf.STT_FUNC, OffsetGOT:0x16ae2b4, OffsetPLT:0x681100, OffsetPLTTail:0x0, Demangled:"ReadingView::prevPageWithTimer()"}: no tail stub before PLT entry

Thanks. I'll make the changes needed to show that this patch no longer works.
