manipulating strings

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.

Re: manipulating strings

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.

Re: manipulating strings

Would this work?

'Uquillas G\''{o}mez' onlyLetters asLowercase

Re: manipulating strings

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 \ { } '`

Re: manipulating strings

Why not use standard collection API?

'Uquillas G\''{o}mez' reject: [ :c | #($\ ${ $} $' $`) includes: c ] thenCollect: #asLowercase

copyWithoutAll: does not work ?

'Uquillas G\''{o}mez' copyWithoutAll: '\{}''`' -> 'Uquillas Gomez'

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

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