Can anyone recommend a simple text UI (something like Newt) which

I was trying to use writef("Escape string" ~ "Display string") to
simulate a full-screen console. But writef doesn't seem to flush

I would have expected a 'flush()' function, but 'flush()' itself

Hi,
Please, under Debian / GDC, what functions are available to read
keys directly as pressed (no wait for )?
And how used (infinite loop exited on specific keycode, eg for
'Esc')?

Agreed.
Suggest 'dec' type.
Example:
dec foo{15,3};
Means simple variable 'foo' can hold fifteen digits, last three
decimal places.

General/Issues/or...
Suppose a program contains several points that control should not
get to.
So each such point is blocked by assert(0).
What is the recommended way of identifying which assert has been
triggered?
Is one allowed anything like 'assert(0,"Crashed at point A");',
where the message goes to stderr?
Please, could someone post here, or provide a link to, some
simple, debugged examples.

I think what you really want is
typeof
The code:
```
void main() {
struct SB {
char SBChrFld1;
char SBChrFld2;
int SBIntFld1;
int SBIntFld2;
}
SB SBVar;
SB* wkSBPtr;
void* StartPtr1 = null;
mixin(mxnDelMbr("StartPtr1", "wkSBPtr"));
return;
}
string mxnDelMbr()(string strStartPt
Suppose we need a construct like:
```
void main() {
struct A {
int I1;
int I2;
char X;
}
struct B {
A Dummy;
int Var1;
int Var2;
}
}
```
But do not want to give an explicit name (like 'Dummy' above) to
the A struct held within the B struct.

And now, returning to the problem after several hours Christmas
shopping, everything seems to work perfectly!
Compile-time:
Is there a 'foo1' that yields 1 from the snippet below?
```
void main() {
import std.stdio;
size_t var1 = 1;
char[4] Txt = cast(char[4])("var1");
writeln(foo1(Txt));
}

Similarly, execution-time, is there a foo2 that wields 2 from the
snippet below:

Hi
I did:
immutable uint MemSize=100; // Memory size in bytes.
// Memory Pool
ubyte[MemSize] MemPool = 8;
And had a look in memory.
I think the compiler set up 101 '8's, not 100 in memory.
Which I did not expect.
Best regards

'Testmain' imports module 'testmod'.
Both are shown below.
I expected 1,1,2,2.
I got 1,0,2,1 - which speaks to scope/extern misunderstanding
Any ideas?
