http://d.puremagic.com/issues/show_bug.cgi?id=2082 Summary: Cannot convert char[] to string Product: D Version: 2.012 Platform: PC OS/Version: Linux Status: NEW Severity: normal Priority: P2 Component: DMD AssignedTo: bugzilla@digitalmars.com ReportedBy: jlquinn@optonline.net This is really ugly. The following program: void test(char[] s) { string t = s; } gives the following error: junk2.d(2): Error: cannot implicitly convert expression (s) of type char[] to invariant(char)[] I haven't found a way around this yet. It really should be handled as an implicit conversion, with a copy being made under the covers as needed. -- |

I think you need to use .idup

Posted in reply to d-bugmail | http://d.puremagic.com/issues/show_bug.cgi?id=2082 ------- Comment #2 from jlquinn@optonline.net 2008-05-08 17:23 ------- To me, this seems like it's going to clutter commonly occurring code. Since char[] and string are similar, and the language is generally trying to treat them like built-in types, I would hope this kind of conversion was transparent most of the time. -- |

Use idup() to make a new invariant copy or use a cast (via assumeUnique from std.contracts?) if you can guarantee the data is invariant. -- |
