Re: How get struct value by member name string ?
A correction:
string getTMember(T t, string columnName) {
foreach(member; __traits(allMembers, T)){
if (member == columnName) {
return __traits(getMember, t, member).to!string;
}
}
return "";
}

Problem: memberName is not known at compile time.
The problem is that you stored the member name list as a
runtime variable, and that is not known at compile time. Try
the enum.
Or really, just `foreach(memberName; __traits(allMembers, t))`
right in the diet template.

Ok, thanks for all you gentlemen's help. I tried following
function,
now it works like C/C++/Python way:
string getTMember(T t, string columnName) {
foreach(member; __traits(allMembers, T)){
if (member == columnName) {
return __traits(getMember, mcu, member).to!string;
}
}
return "";
}

It seems I can't use variable as member name:
struct T {int a; string name;}
T t;
string s = "name";
writeln(__traits(getMember, t, s));
Above code fails to compile. Any help?
Short answer:
`s` must be known at compile-time. Or more precisely, known at
the time of template expansion. In this case, use `enum`:
enum s = "name";
Long answer:

My database table is very wide, with many columns. Above ddbc
allows a struct
to map db returned data. Then if I want a member's value to show
in vibe.d template,
how do I use a function to get it?

you should generally getMember on a variable
T t;
__traits(getMember, t, "name")
like that, that's as if you wrote t.name

struct T {int a; string name;}

How get struct value by member name string ?
I saw ddbc
(https://github.com/buggins/ddbc/blob/master/source/ddbc/pods.d)
uses
static if (__traits(compiles, (typeof(__traits(getMember, T,
m) {
__traits(getMember, T, m)
}
But for my experience, above code sometimes/somewhere works,
sometimes/somewhere just doesn't:
Error: variable `column` cannot be read at compile time
Is there any friend can explain some more details?

Now I found I can read both UTF8 and UTF-16LE chinese file: string txt = std.file.read(chineseFile).to!string; and write to UTF8 file: std.file.write(utf8ChineseFile, txt); But still need figure out how to read/write GBK directly.
