ZnUrl>>#withPathSegments: Surprise

Administrator

I expected #withPathSegments: to return a copy with path segments replaced by the argument, but in fact they were added to the existing path. Just me?

Cheers,

I don't know.

If you see where it is used, you'll see it makes sense to add:

'<a href="http://host.com:80'">http://host.com:80' asZnUrl / 'files' / 'readme.txt'

Where #/ is equivalent to #withPathSegments.

I do remember adding this especially for you ;-)

Ha ha, yes I remember... the #/ is certainly useful. My question is just about the name #withPathSegments:. Maybe something like #withAddedPathSegments: might be clearer? Also, there is the #copyXyz convention used elsewhere in Pharo. Maybe #copyAddingPathSegments: for uniformity?

Maybe, but where do you find proof for the #withX: meaning 'replace X in a copy of the receiver ' ? I mean, it does not strike me as confusing. Of course, the longer #copyAddingPathSegments: is long and clear.

I guess from the collection #with:... messages that start from a fresh copy, but also quickly browsing the image, I see other such uses e.g. #withAngle:, #withNewSelection:, all of which return a new instance with the argument passing through to it independent of the original value.
