Hi Jacob,
Apologies for the oversight. I take it it's okay if Walter uses your
code to build the distribution automatically? If so, what are the
similarities and the differences with Michel's approach?
I think I can answer that.
* Jacob's installer includes DMD directly inside the installation
package, which I believe is more practical for the user, but less for
the maintainer as the installer needs to be rebuild for each new
release. My installer downloads the latest version during the install.
I do this so I can host the installer on my website with no licensing
issue and update it only when releasing a new version of D for Xcode.
* Jacob's installer installs in /usr/share/dmd and creates symlinks in
/usr/bin and /usr/share/man. D for Xocde installs DMD 1 in
/Library/Compilers/dmd and DMD 2 in /Library/Compilers/dmd2 (user
visible folders) and makes symlinks in /usr/local/{bin,lib,man}.
* Jacob's installer requires a modified dmd.conf file. Not with my
installer. With mine, once the symlinks are in place you can just swap
the dmd or dmd2 folder in /Library/Compilers with a newer one from
Digital Mars, but you'll need to set the executable bits manually
(because Walter's archives comes without the executable bit set).
* With Jacob's installer, DMD 1 and DMD 2 will overwrite each other (or
so I believe). My installer is meant to have both dmd1 and dmd2 usable
at the same time. Essentially the symlinks /usr/local/bin/* pointing to
/Library/Compilers/{dmd,dmd2}/osx/bin/* are arranged to that you can
call 'dmd1' and 'dmd2' from the command line to get either one or the
other, and 'dmd' will call either dmd2 or dmd1, which you can change
with the 'sudo setdmd 1' or 'sudo setdmd 2' command. This mimics
somewhat how Apple bundles multiple versions of GCC in the Xcode
package and allow changing the default version.
As a side note, my D plugin for Xcode expects DMD to be available at
/usr/local/bin/{dmd,dmd1,dmd2} and the runtime libraries should be in
/usr/local/lib. It won't work if the files can't be found there,
although I might change that if an official distribution of DMD
installs itself elsewhere.
