Issue ID: 18599
Summary: std.format %(...%) format does not allow modifiers
that take additional arguments
Product: D
Version: D2
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: P1
Component: phobos
Assignee: nob...@puremagic.com
Reporter: hst...@quickfur.ath.cx
Currently, this is supported:
-----
import std.format;
format("%(%.14f, %)", [ 1.1, 2.2, 3.3 ]);
-----
and so is this:
-----
format("%(%10.3f, %)", [ 1.1, 2.2, 3.3 ]);
-----
However, this is not supported:
-----
format("%(%.*f, %)", double.dig, [ 1.1, 2.2, 3.3 ]);
-----
Nor this:
-----
format("%(%*.3f, %)", 5, [ 1.1, 2.2, 3.3 ]);
-----
Basically, any nested specifier that takes an additional argument is not
supported, because of the way nested specifiers are implemented.
It would be nice if this could somehow be made to work.
