[Question] How to use condition?

[rEnr3n]

I want to make use of the end part of this url for my directory naming. https://www.instagram.com/p/B6RlaWXJZ3k/

IG posts with multiple media has sidecar_shortcode while posts with single media has shortcode. How can I use shortcode instead if sidecar_shortcode is missing?

"directory": ["{category}", "{username}", "{date:%Y-%m-%dT%H:%M:%SZ} {sidecar_shortcode}"]
This is my config right now.

Not possible at the moment, but it'll probably look something like {sidecar_shortcode|shortcode} (meaning: "use sidecar_shortcode and, if that's not defined, fall back to shortcode")

Maybe it would also be in order to change/cleanup the (sidecar_)shortcode labels, so that shortcode is always the top-level code and sidecar_shortcode (or some other name) is the code of child media objects

I would like this as a generic solution.

And +1 for consistency.

I would like this as a generic solution.

That's now implemented in v.1.13.0.

And +1 for consistency

Well, I ultimately didn't change anything in that regard, because it actually is consistent as is:

• shortcode always references the individual image/video in question and is also the top-level code for posts with just one image/video
• sidecar_shortcode references the top-level "SideCar" object for posts with multiple images/videos

So {shortcode} is always the image shortcode and {sidecar_shortcode|shortcode} is always the top-level shortcode

@mikf I'm dealing with a submission that erroneously has a None date. Unfortunately, my filename string breaks when you customize the format string like this: {date:.%Y%m%d_%H%M%S}
[error] FilenameFormatError: Applying filename format string failed (TypeError: unsupported format string passed to NoneType.__format__)

When changed to just {date}, it instead prints the text 'None'. A fallback will work without customizing the date format, but all my files are already in the other style. Ideally, I want it to be blank when I hit a rogue submission that doesn't have date metadata for whatever reason.

Ideally I would like something akin to {date:.%Y%m%d_%H%M%S|} (a pipe with no fallback), where if it catches that NoneType.__format__ error, it is instead blank.

[mikf]

Try {date:?//%Y%m%d_%H%M%S}. This will either be the formatted date, or an empty string if date is None (or any other falsey value).

The | gets only recognized in the data-selection part before the :, by the way: {date1|date2|date3:%Y%m%d}

@mikf That works, thank you.

@mikf For twitter, how can I fallback to tweet_id if retweet_id is 0?

I want my config like this:
"directory": ["{category}", "{author[name]}", "{date:%Y-%m-%dT%H:%M:%SZ} {retweet_id|tweet_id}"]

[mikf]

@rEnr3n {retweet_id|tweet_id} should now work: 65744a7
