[Patches] Extra EPUB Metadata

[magicmeth]

I have created some user-patches for KOReader, after being annoyed by some limitations of KOReader. Each patch is compatible with SimpleUI and configurable in the patch file.
Download (and source code) here.

2-lang-quotes.lua
User-configurable automatic <q>-tag localization (including nested) based on epub's embedded language tag. Includes configurable fallback-style (default en-US). Matched case-insensitively, more specific keys win (en-GB > en).
Examples in the git.

2-epub-extra-metadata.lua
Extracts more metadata from epubs, and writes it to a custom file in the sidecar. Currently only extracts (because I only need/want) the following: title-type subtitle, and contributors-type translator and illustrator.
Doesn't add to anything else, without any of the next patches.

Only extracts from books without sidecar, and because it reads all metadata on opening a folder (otherwise, you'd have to open the book first before it'd extract), the first time it can be SLOW.

2-ui-display-title-with-subtitle.lua
Patches native and SimpleUI views to use a display title (Full Title) combining the title with the previously extracted subtitle in the sidecar. Toggles in the patch to enable/disable (everything enabled by default) injection. Option in Status Bar config to add Full Title to the status bar.

2-ui-authors-with-roles.lua
Does two things, each togglable in the patch:
Comma-separated authors: Authors are separated by a comma, instead of a newline. Only newlines when overflow is required for word-wrapping.
Add contributors: Adds contributors previously extracted, with a suffix, to the author display. Boolean each for Translator and Illustrator.


Screenshots in the Git.



Patches were largely generated by Grok, as other LLMs failed me, with some manual edits. Each patch I have tested and confirmed to do exactly what I wanted to do on my Pocketbook Verse Pro.
Do whatever you want with them .
