Here's an example of the replace word:
USING: peg peg.search ;
: bold ( -- parser )
[
"*" token ,
[ CHAR: * = not ] satisfy repeat1 ,
"*" token ,
] seq* [ second >string ] action ;
"Hello *World*" bold [
"<strong>" swap "</strong>" 3append
] action replace .
=> "Hello <strong>World</strong>"
For more, there's now a search and replace chapter in my
work-in-progress factor articles PDF which works with latest git:
