- wrap command-line retrieval of fileName with an implicit validate.
Instead of this:
fileName input(args[1]);
fileName other(args["someopt"]);
Now use this:
auto input = args.get<fileName>(1);
auto other = args.get<fileName>("someopt");
which adds a fileName::validate on the inputs
Because of how it is implemented, it will automatically also apply
to argList getOrDefault<fileName>, readIfPresent<fileName> etc.
- adjust fileName::validate and clean to handle backslash conversion.
This makes it easier to ensure that path names arising from MS-Windows
are consistently handled internally.
- dictionarySearch: now check for initial '/' directly instead of
relying on fileName isAbsolute(), which now does more things
BREAKING: remove fileName::clean() const method
- relying on const/non-const to control the behaviour (inplace change
or return a copy) is too fragile and the const version was
almost never used.
Replace:
fileName sanitized = constPath.clean();
With:
fileName sanitized(constPath);
sanitized.clean());
STYLE: test empty() instead of comparing with fileName::null
