Rewrite Tool Conundrum

Howdy folks,

The use of “`@statements” type meta variables in the Rewrite Tool is nto doing what I’d expect.

I created a subclass of Object named Thingy, with a single method. For the purpose of this example, I just left it in the Base VisualWorks bundle.

initialize

self yourself.

self printString.

self perform: #yourself.

self halt.

self yourself.

^self

Then, I click on the Base bundle in the browser, go to the Rewrite tab and do the following search:

`obj perform: `#symbol.

The pattern matches and finds my initialize method. However, if I search for:

`obj perform: `#symbol.

`@.statements2

`@.statements1

`obj perform: `#symbol.

`@.statements2

Then I find nothing. What gives?

Re: Rewrite Tool Conundrum

I so wish there was a terse, clean Smalltalky way of asking these things
of the Re-write framework. I know that it can be done programmatically but
last I looked at examples it was a bit more involved than what I would
like.

It is a modified Smalltalk syntax, after all, and you also have direct
access to the parse tree if you compose a { } block. The API for the
parse tree seems hairy -- you have to jack around with Dictionaries for
example.

Don't know if it's so much that it's not Smalltalky. More that it's
just hairy to begin with.

Its not *that* bad :) You were just missing a period at the end of the first
line,

`@.statements1.
`obj perform: `#symbol.
`@.statements2

That'll work.

Cheers!
