Bonjour encore Patrick
I realised that my simplistic function had an logic error so that it
only would have processed the first url it came across. I've updated it
now.
highlight-links: func [
{Wraps an <a href> tag around http urls in a string.}
text [string!]
"The string containing http urls."
/local
url-end
"Used to workout where the url ends"
][
while [find text "http://";]
[
text: find text "http://";
;; find char
after url
url-end: copy find/tail text "http:"
until
[
url-end: next url-end
any
[
(url-end = "")
(#" " = first url-end)
(#"," = first url-end)
(#":" = first url-end)
(#";" = first url-end)
]
]
;; insert the <a> tag
either url-end = "" ;; url is at end of
text
[
insert text rejoin
[
{<a href="}
copy text
{">}
]
insert text: tail text "</a>"
][ ;; text after url
url-end: first url-end
insert text rejoin
[
{<a href="}
copy/part text find text url-end
{">}
]
text: find/tail text {">} ;; skip over insert
text: find text url-end
insert text "</a>"
]
]
text: head text
]
Regards
Peter
