Hi,

Going through various posts in the forum and some Q&A, I have put together the below code:

({text.size() >=1 ? 
{text.take(2).collect
	{ a -> allOf
	{ any{a.Language_String3.upper()} {'XSX'} }
	{ a.Format.replace('-':'') }
	}*.joining('-').join(', ')
}: 'No Subs'})

My intention from this piece of code is for it to display,

info about only the first two subtitles,

No subs when there are no subtitles and

XSX when the language of the subtitle is not defined

the above code works fine as long there are 1 or more subtitles but if the media file does not have subtitles then I don't get No subs as the output

.

Any help is greatly appreciated...

thanks,
~kg

If you use text on a file that does not contain any text streams, then the result will not be an empty list, but a binding error that unwinds the expression"
viewtopic.php?t=1895

So we use any to catch that error and print something else instead:

Code: Select all

{
	any{ text.take(2).collect{ a ->
		allOf
			{ any{ a.LanguageString3 }{ 'XSX' }.upper() }
			{ a.Format.removeAll('-') }
			.join('-')
		}.join(', ')
	}{ 'No Subtitles' }
}

Thanks!!!, this works perfectly

I kinda realized the above when I was trying to resolve my issue and wrote the below piece of code.

Code: Select all

{{any{text.size} {0}} >=1 ? 
{text.take(2).collect
	{ a -> allOf
	{ any{a.Language_String3.upper()} {'XSX'} }
	{ a.Format.replace('-':'') }
	}*.joining('-').join(', ')
}: 'No Subs'}

My code snippet above does not work as intended and just for my understanding/learning can someone please advise on what's wrong here?
I am using FileBot GUI and the format editor gives the following error with my code snippet above.

...this again I am unable to understand due to my non-coding background

Please advise.

thanks,

ps: for some inexplicable reason when I put the error that I was getting in FileBot as a text in this response, I kept on getting an 'Internal Server Error' on the website each time I 'previewed' the response. So finally decided to make an image of the error text and post it's url

The outer-most {...} delimitate Groovy code. But Groovy itself uses {...} for code blocks and closures, so inner {...} have completely different semantics compared to the outer-most {...}. Notably, {...} is not used to reference variables, it's used to delimitate Groovy code sections of arbitrary length. It just so happens that simple code like vc is valid Groovy code, making {vc} valid FileBot Format code.

e.g. Groovy code

Code: Select all

// assign "Integer 1" to variable x
def x = 1
// assign "Closure that returns Integer 1 when called" to variable y
def y = { 1 }
