Hi guys. I am a bit lost here and maybe someone can give me a hand. I have a string that may include a single quote inside. Say I have the string 'Sell ''13' . This string actually has a SINGLE quote, so if you print it in a file for example, you get 'Sell '13'. Of course, when you inspect the string in Pharo, it has 2 single quotes: 'Sell '' 13'. ok? Now...what I need is (quite weird I know) is to build a closure as a string and using the previous string as a literal of the closure. Imagine there is no single quote problem in my string, this would work perfect: (Compiler evaluate: '[ ', ' Transcript show: ', 'Sell ' surroundedBySingleQuotes, ']') value. But, if instead of having 'Sell ', I have 'Sell '' 13', like this: (Compiler evaluate: '[ ', ' Transcript show: ', 'Sell '' 13' surroundedBySingleQuotes, ']') value. I get a SyntaxError of a unmatched string: [ Transcript show: 'Sell ' 13Unmatched string quote -> '] So...what can I do? I GUESS the solution is to scape that. If I try adding 2 more single quotes, like this: (Compiler evaluate: '[ ', ' Transcript show: ', 'Sell '''' 13' surroundedBySingleQuotes, ']') value. it seems to work. If this is correct, is there an easy way (a method?) to scape my string automatically so that it works? Thanks in advance, -- Mariano http://marianopeck.wordpress.com

No It still has a single quote. This is just the reader that reads '' and produces ' '1''3' at: 2 $' '1''3' at: 3 $3

Doesn't just #printString do this? It escapes single strings into doubles - should do what you want if it is definitely a string. -Chris On Wed, Jul 24, 2013 at 8:34 AM, Mariano Martinez Peck < marianopeck@gmail.com> wrote:

Thanks Chris, the #printString was indeed a good idea :) On Wed, Jul 24, 2013 at 1:38 PM, Chris Cunningham <cunningham.cb@gmail.com>wrote:

yes, printString does exactly what you want.
