Hi there,

I can't find any function which will convert a file path from relative 
to absolute. C# and Java both have one: Path.GetAbsolutePath or 
something similar.

Is there one?

Do you think this is a good enough solution?

char[] toabs(char[] filepath)
out (c)
{
	assert (isabs(c));
}
body
{
	return (join(getcwd(), filepath));
}

Cheers,

Reiner

I can't find any in phobos.  I usually end up doing what you do..

 Do you think this is a good enough solution?

 char[] toabs(char[] filepath)
 out (c)
 {
 assert (isabs(c));
 }
 body
 {
 return (join(getcwd(), filepath));
 }


That's almost exactly what I do, but I check to see that it isn't absolute 
already:

if(isabs(filepath))
    return filepath;
else
    return join(getcwd(), filepath);

There are some C functions _fullpath and _wfullpath (unicode) which can  
take a relative path and give the full path. I do not think they are ANSI  
functions however they do appear to exist in the DMC libraries (and thus  
you can use them in D).

eg.

import std.stdio;    //writefln
import std.string;   //toStringz
import std.c.string; //strlen

extern(C) char *_fullpath(char *buf,char *path,size_t buflen);

void main()
{
	char[] abs = new char[100]; //allocate space
	char[] rel = "a\\b\\c";
		
	_fullpath(abs.ptr,toStringz(rel),abs.length);
	abs.length = strlen(abs.ptr); //correct array length
	writefln(abs);
}

This should output <cwd>\a\b\c where <cwd> is the path in which you run it.

Also of note are these functions:
   _makepath, _wmakepath
   _splitpath, _wsplitpath
