At the first glance readOnlyFileNamed:ifNone: seems to be a useful
primitive. But this having the file absent might be just one case. You
could have ifNotReadable:, ifParentFolderNotReadable:.
Also, an error when writing in a file may occur in many different
situation (disk full, file read only, ...).
You may also want to provide handler for each of these situation (e.g.,
writeFileNamed: aName with: stream ifDiskFull: [...]
ifAlreadyExistingFile: [...]...
Agree...
I agree you are improving on the existing code, but I would prefer
something like
file := fd readOnlyFileNamed:name ifNone:[ ^self ].
a solution would be to pass in any Exception into the ifNone: block:
file := fd readOnlyFileNamed:name ifNone:[:ex| ^self ].
Then depending on whether you are actually interested in the exact
reason the file couldn't be created you could look at the exception.
