Happened to stumble across this today, which I thought is a relevant, if
sadly humorous, take on build systems:

I haven't actually used reggae myself, but a cursory look suggests that
this is probably the case.

One of the problems of many Make-like tools is that they offer lots of
freedom, especially when allowing you to launch arbitrary shell
commands. But this also comes with drawbacks, because this touch
command will instantly break Windows builds, might also be a problem
on some non-Linux platforms like macOS. Declarative approach from
tools like dub might be restrictive, but it also lets me as a user
know that I can download an arbitrary dub project and 99% chance it
will just compile out of the box on Windows.


IMO, the ideal situation is a hybrid situation: the underlying build
mechanism should be purely declarative, because otherwise the complexity
just goes out of control and you end up with non-portability,
non-reproducible builds, intractibility of static analysis (e.g., for an
external tool to understand what the build does).  However, quite often
in a large project you need to perform some complex tasks, and doing
this declaratively can be too cumbersome.  So what you want is a
procedural element to the build description that *generates* the
underlying declarative elements of the build.  The procedural part does
not perform any build actions; its job is to generate the declarative
build description.  The actual build is carried out based on this
declarative build description.

Thats an interesting approach. Reggae goes a little bit in that 
direction, right?

If there was an interpreter like

maybe it could run dub with right options and thus won't need a 
build script.

You can add your own logic in main to allow using your build

Nice ... I will perhaps give that a try!

I am a great admirer of tup (especially because they incorporated as the 
first system (that I know of) a filesystem monitor outside of IDEs).

Its language is make like I would say, for that I do not like it that much.

Reggae, the build system mentioned by Adam, supports tup as a backend, 
so you could use that as well

Hi Adam,

thanks for the pointer. I forgot about reggae ;-)
From the documentation it looks more high level and already defines
things like libraries and so on. It's also very ambitious in that it
tries to support different backends!

Mind is more low level (although some language specific things could be
added on top of it.

I like reggaes approach in reading in the "source" and creating 
something new from it (perhaps with dub as library) this could get rid 
of some of the boilerplate of what I have now.


Kind regards,
