I know this has to be a really stupid question, but I haven’t yet found a decent method to do this…
Basically, I want to replace all the occurances of one string with another…ie
“This is a string”, replace “is” with “ain’t” so it reads “This ain’t a string”
I know there is a replace method, but it seems more like a fancy insert method.
My current method runs something like this…
local lstFilter = filterString "This is a string" "is"
if lstFilter.count > 0 do (
local sBuild = lstFilter[1]
for iIndex = 2 to lstFilter.count - 1 do (
sBuild += "ain't"
)
sBuild += lstFilter[lstFilter.count]
)
Although, I’ve just thought of another way.
I was curious what other people do…

Are you using 2008? Because there’s always the AVG substituteString() method. The only downside is it replaces ALL instances, not just whole words, so:
str = "This is a string"
substituteString str "is" "ain't"
Would result in
"Thain't aint a string"
fn replaceWordInString thestr theword toreplace = (
local instring = filterString thestr theword
local outstring = ""
for i=1 to instring.count where instring[i] == theword do instring[i] = toreplace
-- rebuild string
for i=1 to instring.count do outstring += (instring[i] + " ")
outstring
)
test = replaceWordInString "Max script is amazing!" "script" "scripting"
print test
I’m not near a max installation, but this should work, I’m sure it could even be simpler than I have it.

Here’s the replace function I wrote for maxToR a while back:
-- replace all occurances of 'old' with 'new' in 'str'.
-- returns a new string
fn replace2 str old new =
(
local findindex
do (
findindex = findString str old
if findindex != undefined then
(
str = replace str findindex old.count new
)
)
while findindex != undefined
str
)
Example:
replace2 "Hello World! World!" "World" "Jim"
=> "Hello Jim! Jim!"
Ha scorp, moondoggie! Thanks for feedback, nice to see how other people approach a common problem.
Scrop, that looks very close to the idea I’ve had…although I did find a “small” problem with it (but in my case it’s not that big a deal right now), if I use my original example, replacing “is” with “isn’t” will cause an infinate loop (that’s my solution, not yours, I believe the way you’ve constructed your loop will solve the issue)
