ICE string- number of characters

[Chris Marshall]

Hello,

I'm using strings in ICE for the first time. What I want to do is type a string of characters, then get ice to give me the number of characters in the string. I can just manually enter that value, but it would reduce 1 step from the user input if ICE could do it.

Thanks

Chris

Try: string to array > get array size

string to array, get array size ;)

[Leonard Koch]

Hm, unless the characters you are entering follow either this: 1, 4, 6, 9, 3 or this: 4 5 3 2 8 notation, I'm afraid you are out of luck...

If they do, then converting that string to an array(String to Array-node) and then getting the size of that array will work.

I think it doesn't work for strings

[Fabricio Chamon]

... I mean, the "String to array" conversion

Yes that's what I'm finding. It doesn't output the correct result.

[Leonard Koch]

It does as long as you follow one of the notations I described above, so either separated by a whitespace or a comma.

Numbers get converted into the respective scalar they represent and groups of characters or words, get converted to zeros.

It's a little screwy, you have to trick it by for example plugging the output port of the String to Array node into the factor-port of a Multiply by Scalar-node.

[Chris Marshall]

I see. Sorry I though you were saying if I was using one of those notations it would screw up. Well I'll just manually type the number in for the time being as adding spaces or commas will screw it up else where.

Thanks anyway.

[Sebastian Kowalski]

use commas, and after that a split string node, you will be able to seperate the strings into an array

[Stephen Blair]

If it's a string like "Testing" or "1223455" you can do it with a While loop and Get Sub String.
If you can live with that.

have a look a the pic

[Fabricio Chamon]

from what I understood Chris wants a string to char array conversion...not a word array.

[Sebastian Kowalski]

so use char instead a full word. next problem would be how to concatenate all the char back to a full string

[Sebastian Kowalski]

guess the easiest way is to loop thru the whole string

OK got it working. For example my string is "thequickbrownfox". So I use a repeat with counter set to a max value I know will be greater than the string size, so say 100.

Then use Get Sub String to query the string 1 item at a time using the loop value. When the string returns nothing, store the loop value.

That works fine.

[Olivier Jeannel]

Can you post a screen grab ?

[Fabricio Chamon]

that's what I tried at first, but with "while with counter", so that it stops right after the string is empty.. didn't work, got some weird bugs...soft crashing and all those fancy stuff...

[Stephen Blair]

I didn't have any problems like that with this:

Hi Chris,

I did a bunch of custom nodes for string manipulations (on Alan Fregtman's request). They are missing for long in ICE. You could probably do all the string manipulation you need with these.

Please find attached.

Cheers !!

Forgot to mention, all 64 bit Win.

[Chris Marshall]

Great thanks Alok. Will take a look.

I've attached the solution I came up with.

That's super :)

[Alan Fregtman]

Here's a sample setup (screenshot + emdl) I had done with Alok's stringToASCII node:

I'm gonna make more examples when I have more time; maybe in the weekend.
Cheers,

Stephen, thanks for the screenshot. 

I didn't know the condition port also evaluates inside the loop. good to know.

Alok, these nodes are super! thanks for sharing!!

[Fabricio Chamon]

ok I feel dumb about my last sentence: "...didn't know the condition port also evaluates inside the loop."

if not I could never get outside the loop... =)
