I missed context, but if you just want the topological graph,
depanal will give you a module graph which you can then topsort
with topSortModuleGraph (all in GhcMake). Then you can do what you want
with the result. You will obviously need accurate targets but
frontend plugins and guessTarget will

"--make" always requires a full view on all sources. That is, any
imports which cannot be resolved fro

Let's say the hypothetical feature is selected via the GHC flag
"--topo-sort". It would add a step before regular compilation and
wouldn't affect any other flag:
ghc -c --topo-s
Here's what I use:
http://ofb.net/~elaforge/shake/Shake/HsDeps.hs
It's a very dumb but fast parser that figures out dependencies. I use
it for my shake build system. Not sure if it's useful, but there it
is if it helps.
If you have a complicated build setup and you're not using shake,

Hi Gershom,

sadly, no. Firstly, it behaves in the same way as "--make" (i.e. only
looks at source files) and secondly, it produces a Makefile as output.
(I'd be happy though to use the GHC API if somebody could tell me
whether/where this functionalit

Not only that – we also want to be able to distinguish compilation
errors between "caused by students" and "we broke something". Under the
assumption that compilation for libr
