Hi,
I have a hard time reading in a string from a file. I don't get any compile
time or run time errors, but my application does not work reliably when I read
a string from a file. But when I define the same string within my code,
everything runs perfect, allways.
The string I want to use is an OpenGL Shader, but the problem is not to be
related to OpenGL as far as a I see.
Are there some format strings which I need to get rid of, and how ?
I tried:
import std.file ;
string fragString = readText( "Shader.vert" ) ;
import std.file , std.utf ;
string fragString = toUTF8( readText( "Shader.vert" ) ) ;
import std.stdio ;
string text = "" ;
auto file = File( "Shader.vert" ) ;
foreach( line ; file.byLine() ) string ~= strip( to!( string )( line ) ) ;
What else could I try ?
Cheers, ParticlePeter !
OpenGL probably wants a zero-terminated string. It works if you add the
code as a literal because string literals are zero-terminated.
string fragString = readText( "Shader.vert" ) ~ '\0';
Alternatively, you can embed the file in you executable:
immutable string fragString = import( "Shader.vert" ); // read at
compile time
