Re: GHC development asks too much of the host system

      Hi Moritz, thank you very much for this bullet list. No doubt my own 
development workflow could be improved. :)

Hi Hecate,
I don't think this is entirely fair in either direction. So sharing my 
personal experience
might shed some light.  I've often worked on GHC on fairly weak 
machines.  However
the ability to use HLS on GHC or even the ability to load GHC into 
GHCi are fairly
recent additions.
I don't run the full test-suite either much.
The general development experience has more been closer to this:
- pick an issue I want to work on
- checkout the relevant branch (or master)
- kick off a ghc build (hadrian)
- start looking for the relevant code in GHC to address this.
- build a tiny reproducer (if possible, or run the relevant test from 
the test-suite if available) -- once the initial ghc is build.
- hack on the codebase; rebuild (subsequent rebuilds are fairly fast)
- retry the reproducer, iterate until done.
Most of my development has been without much codelevel help and at most a
syntax highlighter. This is decidedly different from the experience 
you can have
working on haskell libraries with the availability of ghcid, hls, ... 
would it be nice
if ghc development would be that nice as well? I'd assume so, I've 
just never
even tried.
Cheers,
 Moritz

Hello ghc-devs,
I hadn't made significant contributions to the GHC code base in a
    while,
    until a few days ago, where I discovered that my computer wasn't
    able to
    sustain running the test suite, nor handle HLS well.
Whether it is my OS automatically killing the process due to
    oom-killer
    or just the fact that I don't have a war machine, I find it too
    bad and
    I'm frankly discouraged.
    This is not the first time such feedback emerges, as the
    documentation
    task force for the base library was unable to properly onboard some
    people from third-world countries who do not have access to hardware
    we'd consider "standard" in western Europe or some parts of North
    America. Or at least "standard" until even my standard stuff
    didn't cut
    it anymore.
So yeah, I'll stay around but I'm afraid I'm going to have to
    focus on
    projects for which the feedback loop is not on the scale of hours
    , as
    this is a hobby project.
Hope this will open some eyes.
Cheers,
    Hécate
