View source for Cuis-Automatically escape a complex string

'''Problem''' You have a long shell command, or an SQL command, or something else which may contain tne <code>$'</code> Character. You can escape the <code>$'</code> by doubling it yourself but it will become quite hard to read your original string. Is there a better way?

'''Solution'''. Yes, there is a nice trick to achieve that.

* Suppose the string you want to quote is <code>echo "i'm nicola, who are you?"</code>
* Open a TextMorph
<syntaxhighlight lang="smalltalk">
te := TextEditor openTextEditor . 
</syntaxhighlight>
* Write the string into it
* Go back to the Workspace and type this
<syntaxhighlight lang="smalltalk">
te model actualContents asString . "=>" 'echo "hello, i''m nicola, who are you?"' 
</syntaxhighlight>
* Voila<nowiki>', you have your string automatically escaped, notice the doulbe $' character in i''</nowiki>m nicola.
* Some time ago I made a [https://youtu.be/clJIJnQ5vQ4 video tutorial] about this with a much worst string. There the procedure is a bit different, it was specific for Squeak.
