Search and replace source code

Hi all,

How do you replace all 'expression1' in source code by 'expression2'?

I can find them with Finder but don't see any easy way to replace them.

My problem is i want to change parameter names in many methods.

Best,

Laura

Hi Laura,

you can use this method:

replaceAll: aString with: anotherString
"replaces aString in source code in the whole image in all methods with anotherString"
((self systemNavigation allMethodsWithSourceString: aString matchCase: false) collect: #compiledMethod)
do: [ :each | each methodClass compile: (each sourceCode copyReplaceAll: aString with: anotherString) classified: each category ]

It will replace all 'expression1' by 'expression2' globally in the whole image. Will take some time

Cheers,

Alex

Hi Laura,

you can use the parse tree rewriter of the Refactoring Browser set. Like
that, you can have a degree of control about what you do replace and on
what.

For example, I'd try something like:

| rewrite |
rewrite := RBParseTreeRewriter new
replace: 'expression1'
with: 'expression2'.
myClass methods
do: [ :e |
(rewrite executeTree: (RBParser parseMethod: e sourceCode))
ifTrue: [ myClass compile: rewrite tree newSource ] ]

I'm not entirely sure it will do what I expect, but I'm trying to learn
to use it more than I usually do, because it's very powerfull.

Another example where the rewriter execute some smalltalk code during
the search replace:

Didn't someone demo a cool rewrite tool GUI recently? I don't remember where exactly...

Yes! Mark Rizun rewrite tool (http://myfuncoding.blogspot.fr/). Recommended!

But you can't have fun and use smalltalk scripts inside your search and
rewrite terms with it ;)
