How to split string by \n?

I tried next query

LET doc = DOCUMENT('https://github.com/events', {driver: 'cdp'})
LET list = ELEMENT(doc, '.footer')[0]
LET str = INNER_TEXT(list) // str contains "© 2021 GitHub, Inc.\nTerms\nPrivacy\nSecurity\nStatus\nDocs\nContact GitHub\nPricing\nAPI\nTraining\nBlog\nAbout"
RETURN SPLIT(str, '\\n')

But it returns not splitted string

[
    "© 2021 GitHub, Inc.\nTerms\nPrivacy\nSecurity\nStatus\nDocs\nContact GitHub\nPricing\nAPI\nTraining\nBlog\nAbout"
]

Hey, did you try without escaping \?
Just RETURN SPLIT(str, '\n')

I'm using v0.16.3 and it still doesn't seem to work. It's not only SPLIT(), but also other functions like SUBSTITUTE().

Could you provide an example?

Sure:

LET propertyUrl = 'https://www.and.immo/venda/pis-escaldes-engordany-suite/522-ref1659'
LET propDoc = DOCUMENT(propertyUrl)
LET property = {
	Bedrooms: SUBSTITUTE(SPLIT(TRIM(INNER_TEXT(propDoc, '.text_home .caracteristiquesfitxainterior')), '                                    ')[1], "\\n", ""),
}
RETURN property

Also, the example code in examples/split-new-line.fql gives me the following error: cdp.DOM: ResolveNode: rpc error: No node with given id found (code = -32000): ELEMENT(doc,'.footer')[0] at 2:11. If I change it to this...

LET doc = DOCUMENT('https://github.com/events', {driver: 'cdp'})
LET str = INNER_TEXT(doc, '.footer')
RETURN SPLIT(str, "\\n")

... then it works, but still doesn't replace the \ns.

Because running ferret --version doesn't return anything I'm doubtful about the version, but I'm pretty sure it's 0.16.3 because in $GOPATH/pkg/mod/github.com/!mont!ferret/ I have [email protected] and [email protected] and in my project's go.mod it's also v0.16.3. It would be nice if --version returned both the cli and the library versions.

Try just SPLIT(str, "\n")

Unfortunately, when you install ferret using go get or go install go does not set the version number. For that, you would need to download a binary.

It works now, thank you very much.
