quick question: What is the most efficient way to covert a
string to a char array?
A string is, by definition in D, a character array,
specifically `immutable(char)[]`. It's not like, for example,
Java in which it's a completely separate type; you can
perform all the standard array operations on strings.
If you need to mutate a string, then you can create a mutable
`char[]` by doing `somestring.dup` as Dennis already
mentioned.
The problem I was having was actually that an opengl function
(specifically glShaderSource) wouldn't accept strings. I'm
still can't get it to work actually :P
glShaderSource (uint, int, const(char*)*, const(int)*)
This one function is a bugger, been going at this for hours.

Thx for the heads up
glShaderSource accepts an array of null-terminated strings. Try
this:
import std.string : toStringz;
string sources = source.toStringz;
int len = source.length;
glShaderSource(id, sources, 1, &sources, &len);
src:
string source = readText("test.glvert");
const string sources = source.toStringz;
const int len = source.length;
GLuint vertShader = glCreateShader( GL_VERTEX_SHADER );
glShaderSource(vertShader, 1, &sources, &len);
pt.d(26): Error: cannot implicitly convert expression
(toStringz(source)) of type immutable(char)* to const(string)
pt.d(34): Error: function pointer glShaderSource (uint, int,
const(char*)*, const(int)*) is not callable using argument types
(uint, int, const(string)*, const(int)*)
-
I also tried passing the char array instead but no go.. What am I
missing? :\
