Bug ID: 160
Summary: Support for "Variable Templates" missing/broken
Product: GDC
Version: 4.8.x
Hardware: All
OS: MinGW
Status: NEW
Severity: normal
Priority: Normal
Component: gdc
Assignee: ibuc...@gdcproject.org
Reporter: p.remm...@arcor.de
Reading the "D Programming Language" CHM Guide from my DMD installation,
I found the chapter about templates, which says:
Variable Templates
Same as aggregates and functions, variable declarations with Initializer can
have optional template parameters:
enum string constant(TL...) = TL.stringof;
ubyte[T.sizeof] storage(T) = 0;
auto array(alias a) = a;
These declarations are transformed into templates:
template constant(TL...) {
enum string constant = TL.stringof;
}
template storage(T) {
ubyte[T.sizeof] storage = 0;
}
template array(alias a) {
auto array = a;
}
When I tried the short forms of these examples with GDC, I got a bunch of
errors (semicolon expected following function declaration). Basically, GDC does
not recognize them as variable templates. Checking with DMD resulted in no
error messages.
I'm on Windows, using this package:
https://bitbucket.org/goshawk/gdc/downloads/GCC-4.8-MinGW-GDC-.7z
D:\workspace\dtest>gdc -v
Using built-in specs.
