Hi Alex, thanks! And in case it's a personal private wiki one could even outcomment the new syntax element and eliminate the check for an schrieb am Do., 13.

Hi Thorsten, > I thought about security too.

A public Wiki can be edited by everyone and malicious HTML code might sneak in. As discussed yesterday, I commented the change in the release and on the public site. It is useful in environments where edit access is controlled, so it can be un-commented in such cases. Released. ☺/ A!ex -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe
Re: PicoLisp Wiki: Embed Content?
Hi Alex, simplification looks good, will test later. I thought about security too. I even would like to have 2 embed options, one only for iframes, the other for any html (produced by an external tool)

Thanks!!
I simplified this a little to:
("§" # iframe
(let Lnk (till "}" T)

Re: PicoLisp Wiki: Embed Content?
Hi Alex,
it's actually extremely easy to embed content in a picolisp wiki file, when
adding the syntax element from the PS 1 to wiki/lib.l :

PicoLisp Wiki: Embed Content?
Hi List,
is there a way to embed content in a PicoLisp Wiki file?
I can download the video, add it to the page, and then reference it by
name @{}.
But when sharing e.g. a youtube video, there is the "embed" option, that
gives this iframe:
https://www.youtube.com/embed/xEKHU4zCRpY; title="YouTube video player"
frameborder="0" allow="accelerometer; autoplay; clipboard-write;
encrypted-media; gyroscope; picture-in-picture" allowfullscreen>
I could not figure out how to include this in a page with the PicoLisp Wiki
Syntax - probably it's not possible?
Cheers
Thorsten
