As a workaround, I put the value into an array to make use of the
"undocumented" function formatElement:
"%(%s%)".format([value])
That seems excessive. What happened to format(`"%s"`, s) or
format("\"%s\"", s) or text('"', s, '"')?
Of course, this works well when I know that the value is of type string.
But I have a template and I want to print the representation of (T value):
"hello" (with quotes) or just 42 (without)
Phobos does this for array elements, but it seems that there's nothing
like 'repr'?
I don't know a Phobos function either but the following should work:
import std.stdio;
import std.traits;
void pp(T)(File output, T value)
{
static if (isSomeString!T) {
output.writef(`"%s"`, value);
} else {
output.write(value);
}
}
void pp(T)(T value)
{
pp(stdout, value);
}
void main()
{
pp("hello");
pp(42);
}
