Not clear how scheduling works

[a12rodgers]

Let's say I have two news feeds:
- NewsDaily (marked schedule for download every 1.0 days)
- NewsWeekly (marked schedule for download every 7.0 days)
- NewsMonthly (marked schedule for download every 30.0 days)

I set these up just fine on Sunday. They downloaded, converted to MOBI, and were sent to my Kindle. No problem.

Now let's say it's Monday. I would think that if I clicked on "Download all scheduled news sources," only NewsDaily would download. But when I clicked on them yesterday, all feeds downloaded. And when I opened up Calibre today and clicked that option, all three feeds downloaded again.

Does scheduling mean something different than I think it does? Is this some kind of timer that works only if Calibre stays open for a full 24 hours (at which point, NewsDaily will kick off again)? What if I just leave the computer off and turn it on in a couple of days -- should the NewsDaily kick off again?

Is there any other way (short of manually triggering each download) for Calibre to automate retrieval at given intervals?

Scheduling means that they will automatically download when the 1,7 or 30 days has expired. You need do nothing, when the time is up and calibre is running then they, the news source, will be downloaded without intervention from you.

If you "Download all scheduled news sources," then ALL news sources that are in the schedule area will be downloaded. This a way to manually download every news source you have set a schedule time on.

Yes, see above.

The timer works regardless of whether calibre is active or not. Check the recipe schedule you will see how long it has been since it last downloaded.

Yes it will kick off again. When you start calibre it will see the time has come and gone and automatically download the NewsDaily.

If you know how to run a chron job from the command line you can schedule calibre to download any recipe via the ebook-convert module (see manual).

Thanks, Walt! It would have taken me a lot of trial and error to get to that understanding. I'll rework how I've done my scheduling, and will give it another shot.

FYI: The ebook-convert module produces an EPUB ebook from the designated recipe. It puts it in the default directory (unless another directory is designated in the command line.) That's all it does. It doesn't add the book to the Calibre Library the way a scheduled recipe run does.

how would you duplicate a gui recipe run from the command line?

Start Calibre gui when the recipe is scheduled to run or command line run the recipe, followed by import the format created by the recipe (that's close, but not identical).

and then would you need to invoke the smtp command to mail it? can these all be run in a batch file, sequentially or do they need to be set individually?

Yes.

The batch file needs one ebook-convert line for each recipe you want to run, plus one for each that you want to send to the database, plus one for each that you want to email. They can all be in one batch file or in separate batch files. Is that what you were asking?

yes. thank you very much.
