Adding method to Character

Hi,

I find myself wanting a Character>>isConsonant method in addition to the existing Character>>isVowel method. It might be defined as

Character>>isConsonant

^ self isLetter & self isVowel not

My question is: what is the best way to do this?

Should I simply add the method to Character? If I do, I guess I must remember to merge my Monticello changes into each new version of Character? Is there some way to bundle this change in my package so I don't forget?

I have created a method in my class MyClass>>characterIsConsonant: aCharacter, but it doesn't read well in the code.

I suppose I could add the method dynamically in my class's initialize method... Not sure how to do that exactly.

Is there another way to do this that I haven't thought of?

Thanks,

Stéphane Ducasse

but if you add this method in the character class as a class extension of your package then the addition will be done automatically each time
you load it.

Re: Adding method to Character

After a little research...

Great! The last time I used Smalltalk there were no packages. What a useful concept class extensions are.

Is the best way to see a package's extensions to just browse the package (i.e. Ctrl-P in the packages pane of the browser)?
