I've had the Gcal reader installed and working for about half a year now but it's now showing Invalid Feed Format, Could not identify a valid feed format. I have tried giving the reader another XML address and it still isn't working.

Google obsoleted the V2 API spec as of November 17th - https://developers.google.com/google-apps/calendar/v2/developers_guide_protocol

I suspect Gcal is using V2 and will need to be updated to use the V3 version.

You can change the feed from https://www.google.com/calendar/feeds/username/public/Full to https://..../basic to at least get the calendar items.
Unfortunately this won't give you the time of the events, just the event name. Click through still works though.

As an alternative I installed Rainlender (http://www.rainlendar.net/cms/index.php). It's not a Rainmeter skin, nor is it free, but it does a very nice job of presenting calendar information on the desktop.

I've looked at the lua script. The logic is sound, and when I manually retrieve the link to a GCal RSS feed it is formatted as expected by the script. I haven't been able to figure out why the script can't parse the feed correctly anymore. It is looking for text that is specific to GCal feeds, and that text is still in the feed, but the script doesn't appear to be finding it anymore.

Just a questions, how to edit the event's time/date format? In fact, all the events now showing 12.00AM.....
Example: mine is showing the Event's date/time as 12.00AM on 29 December 2014, can i change to 29 DEC 2014 - 12.00AM?

Please advise, thanks!

Change the Output function from:
local Timestamp = SELF:GetOption('Timestamp', '%I.%M %p on %d %B %Y')
to
local Timestamp = SELF:GetOption('Timestamp', '%d %B %Y - %I.%M %p')

Just read the Lua documentation to change it further http://www.lua.org/pil/22.1.html

@steventan11 are you using the latest version of the Reader.lua file we've been working on? Reinstalling Enigma alone will not fix the calendar. @Gregory2001 you've just shown this is a problem with you PC setup and not Enigma if going to the URL in a browser doesn't download the feed.

Thanks to all who have helped sort this out. I'm so thrilled to have my calendar back on my desktop!

I have updated my reader.lua file with the pastebin file that t0mmy9 provided, along with the changes to show the title and yearly events correctly. But I'm still having one odd problem - there are some events that are still acting strange. For example, I have a birthday listed as a recurring yearly event on September 23, but for some reason Enigma is showing it on January 23. Another is that I recently added an event, then edited the title of the event, and Enigma is showing the edited version and the original version as two separate events on the same day.

Not sure if these are Enigma problems, or something to do with Google. Any thoughts would be most appreciated. Thank you!

EDIT: Interesting. I deleted the birthday from Google Calendar, then created a new event for it and refreshed Enigma. It got the date right this time, but for some reason it is forcing the birthday onto the Enigma list of events, even though it is 9 months away and there are many other events before that. UGH! Why can't Google leave well enough alone????

Just checking in again to see if there has been any progress on this.

Regarding my post above - I have realized that the problem is with recurring events that are on some kind of weekly recurrence. For example, I have one event that recurs every two weeks, and only the first event is showing. I have another that recurs every six weeks, but I have changed the title on each event, and they are showing up fine, although the first one I created is showing up twice - once with the original title, and once with the changed title.

Very strange.

I hope someone is able to come up with a solution. I didn't realize that I had grown so dependent on seeing those events on my desktop!

Thanks to all who are working on this. What would we do without you? :)

I just wanted to say a massive thanks for the huge effort put in by everyone since I first started this thread (especially as I haven't actually done anything). It's always good to see people who are willing to keep trying to get the results they want.

Because I don't have much knowledge of lua and how the Reader.lua file that @t0mmy9 posted actually works, I wanted to pick the brains of those who did. My GCal seems to be working perfectly, even with today's events showing up correctly, I am however still getting the issue related to Untitled calendar names. Any ideas?

commented Jan 31, 2016

No problem :)
The best method to fix any of these problems is to go to the ics link in your browser and open the file that gets downloaded in a text editor and check what's in there.

For the main calendar title it's looking for the line begging with "X-WR-CALNAME" that should be near the top of the file. For events it is looking for the "SUMMARY" and "DESCRIPTION" lines. There are duplicates in the downloaded feed causing problems. There's also various checks trying to remove duplicates so if there are 2 events with the same details one may get removed.

You can see all the checks being done in the "DefineTypes" function in Reader.lua. At the moment it does yearly, monthly, day and nth day of month events. Every 2 weeks probably won't work. Compared to the previous format this is horrible, events don't repeat and nothing is in order or consistent. I would need to know what the "DTSTART" and "RRULE" lines look like for any broken events.

Thanks for that @BillFarquharson, I probably should look harder next time and thanks @jayzee2001 for the fix.

Thank you @t0mmy9 for the run through for that too, it was very helpful. I'll see if I can get a crash course in lua and try to help out with the duplicates problem. And it may be horrible but it's a start and it's a pretty good start at that too.

Do you think you can incorporate the fix that @jayzee2001 and you wrote into the current lua file in pastebin?

@t0mmy9 I am sorry but I was not able to follow what happened here, are you using the standard Enigma calendar here? What files do I need to replace? I'm somewhat illiterate in terms of Rainmeter but I really want to get a working calendar function. Could you make a simpler guide as to the steps neccesary for the default enigma calendar? Or lua calendar or something?

Hey @kirbyplz. So firstly this is for the GCal part of Enigma which can be found in Sidebar --> Reader --> Gcal, not the Calendar in Sidebar --> Calendar. If GCal is what your looking for then great, here's what to do in a basic form.

This is not an entire fix. The good people here have done a lot but are not magicians so there are still a few bugs.

GUIDE:
1.
You firstly want to download the lua file that @t0mmy9 made which can be found here: http://pastebin.com/MA1FxgED

2.
You next want to open it with a text editor and add in the following code from @jayzee2001 into line 83.

        -- GET NEW DATA

         if (t == 'GoogleCalendar') then

            Feeds[f].Title = Raw:match('X%-WR%-CALNAME:(.-)\n') or 'Untitled'

        else

            Feeds[f].Title = Raw:match('<title.->(.-)</title>') or 'Untitled'

        end

        Feeds[f].Link  = Raw:match(Type.MatchLink) or nil

        local Items = {}

This code will replace this bit:

            -- GET NEW DATA
            Feeds[f].Title = Raw:match('<title.->(.-)</title>') or 'Untitled'
            Feeds[f].Link  = Raw:match(Type.MatchLink)          or nil

            local Items = {}

And should end up looking like this: (This is taken from line 80 to 104)

           -- MAKE SYNTAX PRETTIER
            local Type = Types[t]

            -- GET NEW DATA

             if (t == 'GoogleCalendar') then

                Feeds[f].Title = Raw:match('X%-WR%-CALNAME:(.-)\n') or 'Untitled'

            else

                Feeds[f].Title = Raw:match('<title.->(.-)</title>') or 'Untitled'

            end

            Feeds[f].Link  = Raw:match(Type.MatchLink) or nil

            local Items = {}
            for RawItem in Raw:gmatch(Type.MatchItem) do
                    local Item  = {}

                    -- MATCH RAW DATA
                    Item.Unread = 1

                    if (t == 'GoogleCalendar') then

etc...

3.
The next thing to do is take your newly modified lua file and rename it to "Reader" so the whole file is now "Reader.lua".

4.
Following this you want to insert this file into Enigma. This is done by taking the new lua file and replacing the old one.

i. Start by finding your Rainmeter folder. (Mine is in my documents)
ii. Go to "Rainmeter --> Skins --> Enigma --> @ Resources --> Measures." (NB. "@ Resources" does not have a space between the "@" and "Resources", Github just thought it was a person).
iii. Rename the current Reader.lua file "Reader.old.lua" (backups are always good).
iv. Take your new lua file and paste it in the old one's place.

5.
Now the options changing. The old reader used an XML file which Google unfortunately dropped support for so now we're using ICAL instead.

i. Go to Google Calendar and then go to "My Calendars" on the right and click the little arrow that appears when you hover over the calendar you want.
ii. Click on "Calendar Settings".
iii. Right click on the "ICAL" button next to Private Address and copy the link.
iv. Paste this link into the Options widget in Enigma in the section marked with a book.
v. Repeat for your other calendars.

6.
Sit back and enjoy a nearly working GCal :-)

I hope this is what you were looking for.

A massive thanks to everyone involved in this and if I have missed any one out let me know and I'll add them in.

No problem @kirbyplz. And I think I've worked out what you've done wrong. You have these two lines missing from your file:

        for RawItem in Raw:gmatch(Type.MatchItem) do
                local Item  = {}

image
(Courtesy of https://www.diffnow.com)

They should be between
local Items = {}
And
-- MATCH RAW DATA
So hopefully adding those back should fix it for you

after four years, this issue is still not resolved, could we now get ICS-to-XML converter (like what #94 wanted) as alternative?

the iCal ICS format is still supported and will not be removed soon, there's even two version (public and private) URL provided for ICS format in Google Calendar...
