Question is : Rivescript doen’t cut the trailing blanks after cleaning punctuation symbols
(I’am using the javacript interpreter,from aichaos/rivescript-js )

for example, with :
+ do you love me
- yes, i do !

if user enter :
do you love me ? (with a blank before ? ), this doen’t match
do you love me?  works well
  do you love me? doesn’t match

I can cut leading blanks before sending the sentence outside RiveScript, but not trailing as the ? are splitted inside interpreter,

=> this must be done inside interpreter.  Is there some option that miss me ?

I tried this in the python interpreter, 1.8.0, and it doesn’t match “do you love me ?” either, but it does match ” do you love me?”

This is probably something to enhanced also in py as you cannot pre-process yourself, as punctuation removal is under interpreter’s responsibility and arrived later.
I just started Rivescript a few days ago and was very surprised that this elementary cleaning was not done: you cannot test with ..me? me ? me ?  by subst.

I really like Rivescript, but I think the user base just isn’t big enough to find all the little issues like this. I experimented some more, and
“do you   love me”
with extra spaces between you and love does not match, and neither does
“do you
love me”
with a newline in the middle, but this does match:
“do you lo
ve me”

I had not yet test your cases, but it seems also to be enhanced as a basic normalization of string spaces before processing.
Nevertheless, it can be done under developer’s responsibility before submission ( reduce several spaces as a single one ). The previous problem cannot be done before, as the symbols removal is done inside the interpreter. As a future, the best way probably could be to inject (or overload) normalizations we want to apply at the different steps. For these days i’ll clean spaces before entering Rivescript.

The space trimming issue (removing spaces from the start and end of the message) has been fixed in the JS version as of v1.1.8; I found the issue is also reproducible in the Python version and therefore probably all of the other versions.

I created a ticket on GitHub to keep track of this issue: https://github.com/aichaos/rivescript-js/issues/57
