Re: [Pharo-users] getting real changes from RB refactoring
Hi peter
is there some filter that will reject RB changes that actually do not do
anything? I.e. applying them would have no effect (same method code,
class, inst var exists, ...).
I do not know.
Do you have an example of when such changes are created?
For methods I can do
reject: [ :each | each oldVersionTextToDisplay = each textToDisplay ]
for adding classes I had to add custom #oldVersionTextToDisplay
```
RBAddClassChange>>oldVersionTextToDisplay
| class |
class := Smalltalk globals at: self changeClassName ifAbsent: [ ^ '' ].
^ '<1s> subclass: #<2s>instanceVariableNames:
<3p>classVariableNames: <4p>poolDictionaries:
category: ''<5s>'''
expandMacrosWithArguments:
{class superclass name.
class name.
class instanceVariables joinUsing: ' '.
class classVariables joinUsing: ' '.
class package name}
```
which is obviously ugly.
Also RBAddClassChange doesn't understand any format where #package is
used instead of #category, or slots are used.
(As defined in RBAddClassChange class>>definitionPatterns , which is
really weird).
We should change this.

There is even special syntax that allows such Symbols to be represented literally. 'a b' asSymbol. => #'a b' Although it might be confusing, I don't see any problem. The concept of 'meaning' is defined by the user, the usage, not by the Symbol itself. A Symbol with a space cannot be a selector (message/method) name, but that does not mean a Symbol with a space could not be useful in some other context. > On 11 Feb 2017, at 05:56, lb wrote: > > Hi, > I know Symbol is subclass of String. > Any string object can become symbol object by sending 'asSymbol' > message.. > I think symbol must has its meaning in common use, so the symbol > should > be composed of alphabet or number ‘without space“. >> >>Different domains have different common usage. >>IIUC, Smalltalk's definition of symbol is from the 1970s. >>Pharo is not overly constrained by Smalltalk traditions, but there >>must be sufficient gain to balance deviations from consistency with >>other Smalltalks. >> > > BUT There are not compliant below > 1.'
