I played a little with it
int f(string fileName = r"someExistingPath") {
auto text = read(fileName);
return text.length;
}
void main()
{
try {
string fileName = r"someExistingPath";
if(exists(fileName))
writeln("File '", fileName, "' does exist.");
auto text = read(fileName);
writeln(text.length);
writeln(f); // **** EXCEPTION HERE
}
catch (Exception e) {
writeln(e);
}
writeln(f);
}
As you see, I mistrustingly inserted a dumb exist test before
attempting to read.
Here's what I came up with (on linux):
- trying with filename r"~/text.txt" (i.e. an existing file in my
home dir) it FAILED.
- trying with the same filename but this time home dir
explicitely written out fully (r"/home/me/test.txt) it WORKED.
- your code did NOT throw where you say it does ("writeln(f)")
but actually in the read call.
Conclusion: I assume D's OS path related mechanisms to be
somewhat dumb. Anyway the code throws where it's supposed to,
i.e. when confronted with a non existing (or not recognized?)
path.
