eg: str = "a b c d"
newStr = str.sub(" ", ", ")
gives me output a, b c d
what i want is a, b, c, d
ow do i make this happen sub isnt doing it for me i guess. I been
looking all through the ruby-doc to no avail.
You want to use str.gsub rather than str.sub. Compare the
documentation of the two:
------------------------------------------------------------ String#gsub
str.gsub(pattern, replacement) => new_str
str.gsub(pattern) {|match| block } => new_str
From Ruby 1.9.0
------------------------------------------------------------------------
Returns a copy of _str_ with _all_ occurrences of _pattern_
replaced with either _replacement_ or the value of the block. The
_pattern_ will typically be a +Regexp+; if it is a +String+ then
no
regular expression metacharacters will be interpreted (that is
+/\d/+ will match a digit, but +'\d'+ will match a backslash
followed by a 'd').
[...]
------------------------------------------------------------- String#sub
str.sub(pattern, replacement) => new_str
str.sub(pattern) {|match| block } => new_str
From Ruby 1.9.0
------------------------------------------------------------------------
Returns a copy of _str_ with the _first_ occurrence of _pattern_
replaced with either _replacement_ or the value of the block. The
_pattern_ will typically be a +Regexp+; if it is a +String+ then
no
regular expression metacharacters will be interpreted (that is
+/\d/+ will match a digit, but +'\d'+ will match a backslash
followed by a 'd').
