Since there are now two D versions, I figured some of you might be
interested in the trick I use on Windows to switch between compilers
easily.

I have DMD 1.016 (Phobos), DMD 1.014 (Tango) and DMD 2.000. Switching
between versions is only two clicks away.

Things you will need:

1. Windows 2000 or above.

2. NTFS file system.

3. http://www.microsoft.com/technet/sysinternals/FileAndDisk/Junction.mspx
This tool lets you create directory symlinks (NTFS junctions).

1. Extract "junction.exe" into your PATH, I simply extracted it into C:\Windows.

2. Extract dmd 1.x into c:\dmd1_phobos.

3. Extract dmd 2.x into c:\dmd2_phobos.

4. Open notepad, copy/paste this into a new file, "dmd1_phobos.bat":

@echo off
rem Deletes the current symlink and replaces it with a new one.
junction -d c:\dmd
junction c:\dmd c:\dmd1_phobos

5. Do the same for your other DMD installations, just replace
"c:\dmd1_phobos" with "c:\dmd2_phobos", etc.

To change between DMD versions, simply double click the corresponding
batch file. The location of the batch files does not matter.

I hope this helps someone out there, it sure did make things easier
for me when playing around with Tango and 2.0 :-)

Cool I didnt know Windows has "already" something that comes close to "real" symlinks.

They aren't.  You need to be very careful with junctions.  Firstly, if you delete a junction directly, you will delete the original folder as well!  To make this worse, there is no way to tell from explorer if a folder is a junction or not.

Anders' trick is still cool, but just be very careful with it.  MS didn't write a tool to create junctions for a very good reason :)

A solution to this would be to change the icon while making the junction.
Anyone changed a folder icon before? Probably just an API call to set file attributes.

Back when I used Windows I used this shell extension which allows you to manage links and junctions from explorer, and it changes the icons. Very handy!

IIRC: you need to create an attrib +hs file[1] called Desktop.ini with something like this in it:

[.ShellClassInfo]
IconFile=C:\Path\to\the.ico
IconIndex=0

Then you need to make sure the folder itself is just +r.

Then somehow get Explorer to flush the icon cache.

[1] Also make sure you remove the archive attribute, since this seems to stuff it up.

Great! But is it necessary to delete the old symlink? It seems to work fine if you don't.
Then, the first time after you run one of your batch files, you can go into explorer and give the 'c:\dmd' folder a funny icon, or set its hidden attribute.
This greatly reduces the chance of inadvertently deleting it, and creating havoc, as Daniel described.

I only deleted the old symlink just in case... if it works without it
that's cool.

Wouldn't setting an icon for c:\dmd affect c:\dmdX_XXX as well? As far
as I know it just places a desktop.ini in the directory that points to
an icon.
