open markdown url | Drafts Action Directory

Action

Posted by @FlohGro, Last update 3 months ago

this action was build by inspiration form this entry in the drafts forum: https://forums.getdrafts.com/t/i-can-t-seem-to-open-a-url-from-a-scrip/6980
Credits to @RoyRogers - i stole some code from your examples and actions..
This action will search the current draft for markdown formatted urls - e.g. (I inserted a „]‘(„ between the brackets to prevent the description to display only the urls):

[Google]‘(www.gogle.com) this is famous search engine
text before [Bear]‘(bear://) and text after
[text in brackets, no problem] [OneNote]‘(onenote://open)
[Google]‘(www.gogle.com)
BBC

It will search through the draft immediately open the url if only one url is inside the draft.
If there are several urls, a prompt with the URL titles as buttons will be displayed to select the url to open.
The urls are opened with safari, to enable „callback“ links (e.g. drafts://open..)

Steps

script

// open markdown url

const content = draft.content;

// regel to match markdown urls "[]()”
let regex = /\[([^\[]+)\]\(([^\[]+)\)/g
// prompt to select the url to open
var pSelUrl = Prompt.create();
// flag to indische if any url was found.
var foundUrlCounter = 0;
// if only one url is in the note - open it directly - first url will be stored in this variable
var firstURL = '';
var urlToOpen;


let foundUrl = findAndStoreUrls();

if (foundUrl) {
  urlToOpen = getUrlToOpen();
} else {
  let message = "no markdown url '[..](..)' found in draft";
  context.cancel(message);
  app.displayInfoMessage(message);
}

if (foundUrl) {
  if (urlToOpen) {
    openURL(urlToOpen);
  } else {
    let message = "no url to open selected";
    context.cancel(message);
    app.displayInfoMessage(message);
  }
}

// functions

// stores the found urls in the prompt as buttons
function findAndStoreUrls() {
  var matches = [...content.matchAll(regex)]
  if (matches) {
    for (match of matches) {
      foundUrlCounter++;
      let description = match[1];
      let url = match[2];
      // add "http://" if the url is no callback url and just witten as domain.
      if (!url.match(/:\/\//)) {
        url = 'http://' + url;
      }
      // add the found url to the prompt
      pSelUrl.addButton(description, url);
      if (foundUrlCounter == 1) {
        firstURL = url;
      }
    }
  }
  if (foundUrlCounter == 0) {
    return false;
  } else {
    return true;
  }
}

function getUrlToOpen() {
  if (foundUrlCounter == 1) {
    return firstURL;
  } else if (foundUrlCounter > 0) {
    pSelUrl.title = "select URL:";

    var didSelect = pSelUrl.show();

    if (didSelect) {
      return pSelUrl.buttonPressed;
    }
  }
}

function openURL(url) {
  let success = app.openURL(url, false);
  if (!success) {
    let message = "failed to open url: " + url;
    app.displayErrorMessage(message);
    context.fail(message);
  }
