String replace

ruby-talk
1

I wondering if there is a string replace function.

I have a string that looks something like:

   2YP/P:[CTYCODE]B/[W_PHONE]/F/[W_FAX]/R/[H_PHONE]

and what I am looking to do is to replace the [W_PHONE], for example,
with 555-555-5555. What I have right now in terms of code is something
like:

  if /\[W_PHONE\]/ =~ 2YP/P:[CTYCODE]B/[W_PHONE]/F/[W_FAX]/R/[H_PHONE]
    @var = "555-555-5555
  end

which works but it builds a new string, which is fine, but the above
string could be constructed any number of ways - with another variable
string to replace on, or with one missing, etc. What I would really like
to do is replace the string in-place of the one that I am searching for.
Is there a built in ruby function to do this or can someone gets me some
pointers about writing one myself? Thanks,

I got it: @freeform = @freeform.sub(/\[W_FAX\]/, "555-555-5555"). I
guess that's what I get for not reading a little further in my Ruby
book.

@freeform = @freeform.sub(/\[W_FAX\]/, "555-555-5555")

Also consider:

@freeform.sub!(/\[W_FAX\]/, "555-555-5555")

With "sub!", you can change the variable in-place.

You might also want String#gsub -- #sub only replaces the first match, #gsub
("global substitute") replaces all matches.
