Splitting text lines into single letters?

Peter Ostry — Wed, 24 Feb 2010 21:16:37 +0000

Target: The user should type two lines of text (up to 32 characters each). Each single letter must be translated to a certain number and the whole bunch sent to a synthesizer display as SysEx.

Problem: Using [umenu] for each letter is not a good option. Would be much better if the user could just type the text in. But I don’t find a way to split a text into it’s single letters. Is there a Max object that can do this? I need a serial output to send the letters sequentially to a [coll] that does the translation.

[atoi]
[zl iter 1]

or something like that might be a good starting point….

in that case you’d probably need to reference each letter as a number, but you could use [itoa] somewhere as well if it’s important to keep them as letters.

Otherwise you could use [regexp (.)], and take your output from the backreference output – so that would solve the problem in one object – so you might prefer it….

[atoi] does what I want.
Thank you!

Oops,
there seems to be a bug in [atoi]. A bang to the left input gets interpreted as a symbol and I get the output “bang”.

I can filter the word “bang” afterwards or maybe only if “bang” stands alone but this is not a good solution. Any other idea?

It’s a feature, not a bug ;)

bang is a symbol like any other. When you send a list with a symbol as first element, the list is interpreted as a message, where the first symbol is the message name. Check the Messages section in the atoi reference and you see that it responds to the messages bang and clear.

Then, how would you get rid of the output “bang” when [atoi] is empty and you bang the left input by a button?

Mhm … I think there is something basic I don’t know …

Got a similar problem with [textedit] – if it is empty and receives a bang, it sends the word “text” out. A [route] afterwards removes the “text” but then I get a bang. [route text bang] doesn’t solve the problem.

—

An empty [atoi] receiving a bang puts out “bang”.
An empty [textedit] receiving a bang puts out “text” and if “text” gets filtered, the final output changes to “bang”.

How do I deal with this, when I don’t want any output?

I’m not sure what problem is trying to be solved here, but textedit is the culprit for putting out “bang” as text. This works around that:

Yes this was the problem. atoi says also “bang”, btw.
Thanks a lot.

I tried almost the same as a workaround with the litte difference that yours works and mine not. So I take yours if you don’t mind.
