Currently, DT3 use the same generic icons as thumbnails for all feeds and posts in them. The appended script instead uses the favicon of the feed’s website, if that can be retrieved as
[http/https]://domain/favicon.ico
That works for a lot of feeds but not all of them. So I’d be grateful for any amendments.
(() => {
let app = Application("DEVONthink 3");
app.includeStandardAdditions = true;
let dbName = "Feedly"; /* NOTE: Adjust this to your database name */
let db = app.databases.whose({name: dbName})[0].root();
let feeds = app.search("kind:feed", {in: db});
feeds.forEach(f => {
let feedURL = f.url();
let URLmatch = feedURL.match(/(https?:\/\/)([^/]+)\//);
let domain = URLmatch[2];
let fullPath = URLmatch[1] + URLmatch[2] + "/favicon.ico";
f.thumbnail = fullPath;
f. children().forEach(c => {
c.thumbnail = fullPath;
})
})
})()
Here’s a revision for smart rules that supports bookmarks & feeds and tries to retrieve the icon from the HTML source:
on performSmartRule(theRecords)
tell application id "DNtp"
if (count of theRecords) > 0 then
show progress indicator "Download Favicons…" steps (count of theRecords) with cancel button
repeat with theRecord in theRecords
step progress indicator ((name of theRecord) as string)
set theType to type of theRecord
if theType is bookmark or theType is feed then
try
set theURL to URL of theRecord
if theType is feed then
set slashes to 0
if theURL begins with "feed://" then set theURL to "https" & (characters 5 thru -1 of theURL)
repeat with i from 1 to length of theURL
if character i of theURL is "/" then
set slashes to slashes + 1
if slashes is greater than 2 then
set theURL to (characters 1 thru i of theURL) as string
exit repeat
end if
end if
end repeat
end if
set theFavicon to theURL & "favicon.ico"
set theHTML to download markup from theURL
set theLinks to get embedded images of theHTML base URL theURL
repeat with theLink in theLinks
if theLink ends with ".ico" or theLink contains "/favicon" then
set theFavicon to theLink
exit repeat
end if
end repeat
set thumbnail of theRecord to theFavicon
end try
end if
if cancelled progress then exit repeat
end repeat
hide progress indicator
end if
end tell
end performSmartRule
Does this work for the “posts” in a feed, too (if that’s the right terminology – I mean the HTML pages in a feed)?
Wouldn’t it be better to replace “feed://” with “http://” and leave it to the website to switch to https? That way the script works also for non-https sites
I guess that the repeat with i from 1 to length of the URL loop gets you the [protocol://domain] part of the URL?
this looks very useful for thousands of my bookmarks. Can anyone write a sentence or two on how to use it?
How do you launch the script it a rule? do i use the execute script?
Don’t plan on “run[ning] it on thousands of bookmarks”.
Especially when dealing with network requests, you should work in smaller batches (which is good advice in general).
You do. It’s all explained in the documentation. Look for automation, smart rules, external script.
Yes, my script is JavaScript. I’m more comfortable with it (and getting the base URL is actually less verbous then in AppleScript ;-). But it doesn’t matter if you use a JS or an AppleScript version of the script, they should do the same (though the one I posted earlier is some way behind what Christan posted, so you might go with his version).
As to “how do I run”: Mark one or two records and then select “Rules” and the rule from bottom of the popup menu.
And heed Bluefrog’s advice: All these network requests take time. Run it in batches
I have the impression that this script works fine as long as the favicon can be found in the html element of the page (or if there is one available at the standard location). However, when it is specified in a link element of the documnent’s head part, it doesn’t work.
Probably because download markup only downloads the element (or does it?) and embedded images is fetching img elements exclusively?
as you suggested, I use the script as external in a smart rule is triggered by “on create” (see screenshot). However, no new posts got favicons. Do you have any ideas on that?
Thanks a lot in advance
I’m running into weird problems with the JS version of the script: It runs ok once if I use “Apply rule” from the context menu, but terminates with an error -1708 (as can be seen in DT3’s protocol window). After that, it throws the same error without even doing anything (I peppered the code with logMessage calls).
If I run the exact same script in the script editor with the current selection (i.e. the same html file as in DT3), it works ok and doesn’t throw an error. Supposedly, this is some kink in JXA, but maybe I’m doing something stupid here?
The first part, up to and including the error message, comes from the rule being run in DT3
The rest is from the rule being run directly in script editor on the current selection.
I’m aware of the fact that DT3 is caching external scripts. What actually happens, is this:
I start DT3
I select a record and run the rule on it
all the messages are logged to the protocol window, including the final error message
I run the rule again on the same selected record
no messages are logged to the protocol window except for the final error message
So it seems that the script is somewhat “tarnished” after being run for the first time.
Since I don’t want to spam the forum, I don’t post the script here right now. Please let me know if I should do that or send it via personal message (or not at all
Most browsers started to block such sites already.
