Description

can someone add support for kindle device kpdfviewer which stores highlights,text in a separate .lua file in the same location.

more info: http://www.mobileread.com/forums/showthread.php?t=157047

sample .lua file:return { ["globalzoom_mode"] = -4, ["highlight"] = { [1] = { [1] = { [2] = { ["y0"] = 209, ["x0"] = 73, ["y1"] = 217, ["x1"] = 510 }, [3] = { ["y0"] = 219, ["x0"] = 73, ["y1"] = 227, ["x1"] = 517 }, [1] = { ["y0"] = 199, ["x0"] = 451, ["y1"] = 207, ["x1"] = 516 }, [4] = { ["y0"] = 230, ["x0"] = 73, ["y1"] = 238, ["x1"] = 522 }, [5] = { ["y0"] = 241, ["x0"] = 73, ["y1"] = 249, ["x1"] = 482 }, ["text"] = "a Wikipedia article and classified into one of five abstract concept categories: Research Field, Technology, System, Term and Other. Using the content of the matched Wikipedia article, the system then constructs a conceptual graph structure representation for each key phrase and the questions are then generated based the structure. To evaluate the quality of the computer generated questions, we conducted a version of the Bystander Turing test, which involved 20 research students who had written literature " } },

the ["text"] field contains the annotation to be extracted. How to modify extract.js to accomplish this?

Research direction
Investigate the Kindle annotation Lua file format linked in the issue (mobileread thread) and the existing extract.js file in the Zotero repository (likely in the 'chrome/content/zotfile/' directory). The goal is to parse the Lua file to extract the 'text' fields from the highlight data, then integrate this extraction into the current PDF annotation extraction pipeline. The issue may require understanding how Zotfile currently processes PDF annotations and extending it to handle this alternative format. Check if any existing code handles similar custom formats, and discuss with maintainers if this feature is within scope.
