[REBOL] how to bind to a local variable
From: alberto:origen:mx at: 10-Oct-2008 10:08
Hi, I'm struggling with the next problem,
I made a small function I use to replace variables inside a string:
rep-vars: func [str /local var beg end] [
parse str [
some [
to ":" beg: ":" copy var to ":" ":" end: (
var: to-word var
change/part beg get var end
)
]
to end
]
]
this function let me replace variables inside a string:
>> var1: "here"
>> var2: "there"
>> str: "some vars :var1: and some vars :var2:"
>> rep-vars str
>> probe str
== "some vars here and some vars there"
what I need to solve is the function only works with global variables,
but of course not from a function using locals:
new-func: func [/local lvar lstr] [
lvar: "locally"
lstr: "a var used :lvar:"
rep-vars lstr ;; ERROR
]
May be the solution is the bind function but I don't get how
any ideas?
BTW, I never before has used the bind function, so I'm an absolute
beginner in "bindology"!
cheers
