I've implemented this for ghc-mod; it seems quite easy to do! All that's needed is replacing |

Using this, full projects can be quickly typechecked, e.g. using
find . -type f -name "*.hs" | xargs hdevtools check
or in shells that support it:
hdevtools check **/*.hs

Hi @nh2, thanks for this. I'm not quite sure why you were originally having problems. As you observed, hdevtools is using lots of memory, and so it should be caching I think it would be worth investigating what's going on here... |

I am currently trying:
and realized that all benefits of hdevtools are lost: Checking
file1.hsthe second time creates a lot of CPU usage, not using any cached results.Why is that?
It is also interesting that despite losing the hdevtools benefits, hdevtools still uses a lot of RAM: Loading a few hundred files easily eats up 10 GB RAM. So there seems to be some caching going on, but not actually being used.
How am I supposed to use hdevtools with multiple files?
