[Feature Request] Customizable Bibtex Key

[thequilo]

Correct me if I'm wrong, but I think it is currently impossible to customize the bibtex key. To match my current zotero setup, I would like to customize the bibtex keys to match those generated by zotero's betterbibtex integration.

I would also be willing to contribute a PR if I'm shown the correct place to start. I'm not an experienced JS dev, though.

Hi, could you please describe what kinds of format do you want?

[thequilo]

In the betterbibtex zotero plugin I have this configuration: auth + year + "_" + shorttitle(3,3), which results in, for example, Levenshtein1965_BinaryCodesCapable.

To match zotero's keys exactly, the title would have to be shortened to three words with unimportant words ignored. For example:

• "From WER and RIL to MER and WIL: Improved Evaluation Measures for Connected Speech Recognition" -> Morris2004_WERRILMER

OK, I would suggest you implement this in a hook extension, it's unnecessary to PR the main app.

https://paperlib.app/en/extension-doc/ext-types/hook-ext.html

We have some hooks for reference exporting. I would suggest you investigate these hooks:

https://paperlib.app/en/extension-doc/process-hook.html#citeobjcreatedinexportbibitem
https://paperlib.app/en/extension-doc/process-hook.html#citeobjcreatedinexportbibtexkey
https://paperlib.app/en/extension-doc/process-hook.html#citeObjCreatedInExportBibTexBody

The reference exporting logics are at here: https://github.com/Future-Scholars/paperlib/blob/main/app/renderer/services/reference-service.ts

Basically, let's use citeobjcreatedinexportbibtexkey hook as an example, if you hook this point, your function in the extension will receive an instance of Cite, and an instance of PaperEntity. the paperEntity contains all info of this paper. You can create your preferred bibkey, and overwrite the citation-key of the cite instance. After that, return the new cite instance, and you will get what you want.

Some useful source codes:

paperlib/app/renderer/services/reference-service.ts

Line 80 in da0f48e

"citation-key": citeKey,

paperlib/app/renderer/services/reference-service.ts

Lines 339 to 346 in da0f48e

	if (this._hookService.hasHook("citeObjCreatedInExportBibTexKey")) {
	[cite, paperEntities] = await this._hookService.modifyHookPoint(
	"citeObjCreatedInExportBibTexKey",
	60000, // 1 min
	cite,
	paperEntities
	);
	}

As this can be achieved via extension, I will close this for now.

If you have any questions about the extension, feel free to tell me.
