Development & Contributing

This addon is built based on the Zotero Plugin Template. See the setup and debug details there.

To startup, run

git clone https://github.com/windingwind/zotero-pdf-translate.git
cd zotero-pdf-translate
npm install
npm run build

The plugin is built to ./build/*.xpi.

Contributing

Add new translate service

  1. Add service config to src/utils/config.ts > SERVICES;
  2. Add translation task processor under src/modules/services/${serviceId}.ts with the same format with other services. The export function set the translation result to data.result if runs successfully and throw an error if fails;
  3. Import the task processor function in src/modules/services/index.ts.
  4. Add locale string service.${serviceId} in addon/chrome/locale/${lang}/addon.properties.
  5. Build and test.

Extra options for translate service

If the service requires extra options, the minimal implement would be putting them in the secret input in the prefs window, like the existing services does.

If there are complex options, please bind a callback in src/modules/settings/index.ts > secretStatusButtonData which create a highly customizable dialog window with ztoolkit.Dialog. See the example of NiuTrans login here: https://github.com/windingwind/zotero-pdf-translate/blob/main/src/modules/settings/niutrans.ts
