Summary: we need (*type).property to refer to property if we use
typedef
Product: D
Version: 1.00
Platform: PC
OS/Version: Windows
Status: NEW
Severity: normal
Priority: P2
Component: DMD
AssignedTo: bugzilla digitalmars.com
ReportedBy: davidl 126.com
module test.test;
class test
{
int myMember;
}
typedef test *ptest;
void main()
{
ptest k;
k.myMember = 1;
}
dmd complains:
test.d(10): Error: no property 'myMember' for type 'test*'
test.d(10): Error: constant (k).myMember is not an lvalue
typedef test *ptest; <--- the problem is here. I think it's
something related to dmd's strong type mechanism.
alias test *ptest; // this would work fine
i don't know if i can call this a bug , but at least the
compile message should be nicer. Leave to u to decide either
this should be a bug or an enhancement.

Because of the 'is a' principle of typedefs, this should work. I call this a
bug.

alias doesn't seem to be any better.
dmd 2.056 64 bit linux,
alias JNINativeInterface_* JNIEnv;
struct JNINativeInterface_ {
int FindClass;
}
void main(){
JNIEnv* env;
auto x = env.FindClass;
}
compiled results in
foo.d(8): Error: no property 'FindClass' for type 'JNINativeInterface_*'

Checked dmd(In reply to comment #3)
alias doesn't seem to be any better.
dmd 2.056 64 bit linux,
alias JNINativeInterface_* JNIEnv;
struct JNINativeInterface_ {
int FindClass;
}
void main(){
JNIEnv* env;
auto x = env.FindClass;
}
compiled results in
foo.d(8): Error: no property 'FindClass' for type 'JNINativeInterface_*'
This case is wrong.
variable env is of type JNINativeInterface_** so compiler rejects invalid code
correctly.
