Would this work? 'Uquillas G\''{o}mez' onlyLetters asLowercase Esteban A. Maringolo 2016-08-10 15:00 GMT-03:00 stepharo <stepharo@free.fr>:

I did

String streamContents: [ :str | aString do: [ :aChar | aChar isLetter ifTrue: [ str nextPut: aChar asLowercase ] ] ]

I'm curious about other solution because I was lucky that isLetter exist.

Hi

I have the following problem I want to transform a string into another while removing a set of characters

'Uquillas G\'{o}mez'

->

'uquillasgomez'

And I wonder how to do that?

copyWithoutAll:

I was thinking to create a string of the same size and copy only the valid characters.

Now I do not know how to set the size of the resulting string.

I could use stream.

Any ideas is welcome.

Stef

Now I was really wondering how I could copy characters by characters without relying on a stream to get a string from the correct size at the end. In particular copyWithout: and friends only works either with one subcollection or one elements and I have mulitple elements \ { } '` Stef Le 10/8/16 à 22:30, stepharo a écrit :

Why not use standard collection API?

'Uquillas G\''{o}mez' reject: [ :c | #($\ ${ $}

There is short version: copyWithoutAll:#($\ ${ $}
