be creative! ;-)
import std.algorithm, std.stdio;
void main () {
string fname = "hello.exe";
import std.path : extension;
if (findAmong([fname.extension], [".exe", ".lib", ".a", ".dll"]).length) {
writeln("got it!");
} else {
writeln("alas...");
}
}
note the dots in extension list.
yet you can do it even easier:
import std.algorithm, std.stdio;
void main () {
string fname = "hello.exe";
import std.path : extension;
if ([".exe", ".lib", ".a", ".dll"].canFind(fname.extension)) {
writeln("got it!");
} else {
writeln("alas...");
}
}
as you obviously interested in extension here -- check only that
part! ;-)
