Custom button to get the URL of a message: WebExtension?

[morat]

I changed userChrome.js code to insert the "Example" button on the mail toolbar in the main window only.

Code: Select all

/* Thunderbird userChrome.js */

// Thunderbird 68 uses the messenger.xul page.
// Thunderbird 78 uses the messenger.xhtml page.

(function () {
  if (location == "chrome://messenger/content/messenger.xul" ||
      location == "chrome://messenger/content/messenger.xhtml") {
    try {
      var XUL_NS = "http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul";
      var toolbarbutton = document.createElementNS(XUL_NS, "toolbarbutton");
      var dataUrl = "data:image/png;base64," +

        class: "toolbarbutton-1 chromeclass-toolbar-additional",
        label: "Example",
        tooltiptext: "Example",
        oncommand: 'Services.prompt.alert(window, "Example 3", document.location.href);',
        style: 'list-style-image: url("' + dataUrl + '"); -moz-image-region: auto;',
      };
      for (var p in props) toolbarbutton.setAttribute(p, props[p]);
      var toolbar = document.getElementById("mail-bar3");
      var appMenuButton = document.getElementById("button-appmenu");
      toolbar.insertBefore(toolbarbutton, appMenuButton.nextSibling);
    } catch (e) {
      Components.utils.reportError(e); // [check] Show Content Messages
    }
  }
})();

The "Example" button inserts after the hamburger button. (also called the app menu button)

No luck for the moment. I tried with the .css file suggested and setting the indicated property, but still no changes.

The output I obtain in the error console using the command indicated is the following:

document.getElementById("mail-toolbar-menubar2").currentSet;
-->
"menubar-items,__unique_identifier_example_button"

If I interpret it correctly, the added button seems to be the only button in mail-toolbar-menubar2.

With "document.getElementById("menubar-items").currentSet;" I obtain the output "undefined".

[morat]

The #menubar-items element is not a toolbar so it doesn't have a currentSet property.

Thank you very much for your help!

Now I managed to get the buttons in the correct place. Using the last two suggestions at the same time solved the problem!

However, I have some problems executing scripts. The following piece of code was working before but not now:

Code: Select all

      
var am = Components.classes["@mozilla.org/messenger/account-manager;1"].getService(Components.interfaces.nsIMsgAccountManager);
    customizedAlert("List of all servers obtained!");

      var allServers = am.allServers;
      var numServers = allServers.length;
    customizedAlert("Number of servers: " + numServers);
    customizedAlert("msgHdr: " + msgHdr);
      for (var i = 0; i < numServers; i++) {
          customizedAlert("Server number " + i);
         if (msgHdr === null) {
            customizedAlert("Querying server number " + i);
            var server = allServers.queryElementAt(i, Components.interfaces.nsIMsgIncomingServer);
            customizedAlert("Server to check subfolders: " + server.prettyName);
                   ...


The messages are printed until "Querying server number 0" (included), but I never get the message "Server to check subfolders: 0". It hangs at "allServers.queryElementAt(i, Components.interfaces.nsIMsgIncomingServer);".

I'm stuck with this, which worked with the previous Thunderbird version. Any idea is welcome.

[morat]

Try something like:

Code: Select all

(function () {
  var allServers = MailServices.accounts.allServers;
  var counter = 0;
  for (var server of allServers) {
    counter++;
    alert(`Pretty name for server ${counter} of ${allServers.length}: ${server.prettyName}`);
  }
})();

Thanks a lot, that solved the problem!!

Now I'm stuck with another problem coming in another one of my scripts:

Code: Select all

   customizedAlert("Debug - parseAddresses 1");
   var hdrParser = Components.classes["@mozilla.org/messenger/headerparser;1"].getService(Components.interfaces.nsIMsgHeaderParser);
   customizedAlert("Debug - parseAddresses 2");
   var uniqueAddresses = hdrParser.removeDuplicateAddresses(addresses, "");
   customizedAlert("Debug - parseAddresses 3");
   var emailAddresses = {};
   var names = {};
   var fullNames = {};
   customizedAlert("Debug - parseAddresses 4");
   var numAddresses = hdrParser.parseHeadersWithArray(uniqueAddresses, emailAddresses, names, fullNames);
   //customizedAlert(addresses + "\n" + uniqueAddresses);
   //customizedAlert(emailAddresses.value + "\n" + names.value + "\n" + fullNames.value);
   customizedAlert("Debug - parseAddresses 5");

This worked with the previous version of Thunderbird (68.12.1), but now it gets stuck at the call to "hdrParser.parseHeadersWithArray": I get the "Debug - parseAddresses 4" message but never the "Debug - parseAddresses 5" message. The "parseHeadersWithArray" function is documented at https://developer.mozilla.org/en-US/doc ... aderParser.

Any ideas are welcome.

[morat]

Try something like:

Code: Select all

(function () {
  var msgHdr = gFolderDisplay.selectedMessage;
  var addresses = MailServices.headerParser.parseEncodedHeader(msgHdr.recipients);
  var out = [];
  for (var addr of addresses) {
    var emailAddress = addr.email;
    var name = addr.name;
    var fullName = addr.toString();
    out.push(emailAddress + "\n" + name + "\n" + fullName);
  }
  alert(out.join("\n\n"));
})();

Thank you very much! This seems to solve my problem perfectly!
