Nunjucks: Filter "replace" not working with regexp

[felipenmoura]

According to the release v1.1.0 ( https://github.com/mozilla/nunjucks/releases/tag/v1.1.0 ), the filter replace should accept RegExps for the first argument.
I am trying this

... | replace( /(https?:\/\/[^ ]+)/ , "<a href=\"$1\">$1</a>" )

And it is triggering:
Template render error:
unexpected token: /

Am I being noob somewhere?

I am having the same problem

Looks like the syntax would be:

replace( r/(https?:\/\/[^ ]+)/ , "<a href=\"$1\">$1</a>" )

(note the r before the regexp)

[felipenmoura]

hm...seems like by using the "r", it stop triggering the error.
But did not apply the replacement either!

Yes, you need to prepend the regex with r, like r/foo/. It probably wasn't matching the regexp which is why the replacement didn't occur. Please reopen/file a new issue if you still have problems!

This needs to be mentioned on the docs!

r/ This is a pit.

Hello, I know that's darn ol' thread.
Just wanna add little info - you should not be using quotation marks "" but use apostroph marks '' instead.
Otherwise you get some errors.
