if (!items?.length) return;

items.forEach(async (item) => {
  const attachment = item.isAttachment()
    ? item
    : await item.getBestAttachment();
  if (attachment?.attachmentPath.toLowerCase().endsWith(".pdf")) {
    Zotero.launchFile(attachment.getFilePath());
  }
});

Anything else

Alternative solutions:

• https://github.com/retorquere/zotero-open-pdf
  A plugin that modifies the context menu.
• [Share]用其他程序打开PDF（Open PDF with specific application） #132
  A similar script, but you have to explicitly specify a PDF viewer.
• https://github.com/wshanks/Zutilo
  A plugin for keyboard shortcuts. Zotero 7 is not supported yet.

Is there a way to define the system pdf viewer hard coded? I am currently using two. Evince and Okular for different purposes and I would like to have two actions "Open in evince" and "Open in okular".

So instead of Zotero.launchFile I would need something like System.call("evince ".attachment.getFilePath()).detach().

Should be this one: #132

Find my solution here:

if (!items?.length) return;

if (!item && !collection) return "[Open in Okular] item is empty";
if (collection) return "[Open in Okular] Cannot open a collection";

async function getAttachmentPath(item) {
  if (item.isAttachment() && !item.isNote()) {
    return await item.getFilePathAsync();
  } else if (item.isRegularItem() && !item.isAttachment()) {
    let attachment = await item.getBestAttachment();
    return await attachment.getFilePathAsync();
  }
  return null;
}

items.forEach(async (item) => {
  const filePath = await getAttachmentPath(item);
  if (filePath.toLowerCase().endsWith(".pdf")) {
    let applicationPath = "/usr/bin/okular";
    let args = [filePath];
    Zotero.Utilities.Internal.exec(applicationPath, args);
  }
});
