Ask, and ye shall receive:
Stick -version=minimal when building reggae itself (or use the
minimal_bootstrap.sh in the repo) and reggae has no dependencies
on anything. All it can do then is D builds and the only backend
is the binary one. No dub support either.
Don't want to build reggae / dub run reggae / run it as a
command-line tool? Run this:
rdmd -I/$REGGAE/src -I$REGGAE/payload -J$REGGAE/payload/reggae
-version=reggaelib /path/to/your/reggaefile.d -b <backend>
Now you have a build wherever you ran that from. Your build
description... becomes reggae itself. To my surprise, you can add
-version=minimal to that command line and it seems to work.
I know, I know, there're loads of flags there right now. It's the
best I could come up with without even more massive amounts of
refactoring. It's silly you still have to specify `-b binary`
when you've built a version that doesn't know how to do anything
else, but... them's the breaks right now.
I've only tried -version=reggaelib on a toy build system and
reggae itself. But it "ourobourosed" nicely. So I'm assuming it
works, but it might not. I was a bad programmer and only tested
any of this manually.
-version=reggaelib only works if the `build` template mixin was
used, which it probably always should. But... there's no change
needed to any exiting build description, just -version=reggaelib
(basically the template mixin expands to something else) and
