Build times of hledger dependencies on a slow machine

Build times in minutes of hledger's dependencies, running cabal and ghc 8.4.4 with a single Cortex-A53 CPU and 4G RAM, emulated on some faster machine.

From xiroux on #hledger:

sm: If you wanna take a look at the times, I just listed the files in .cabal-sandbox/lib/ with their last modification time and computed how much time passed between one file and another. The data is here:

scripts for finding available versions in nixpkgs
View a.bash
# Some nixpkgs query scripts inspired by #nixos chat.
# Goal: find the HASH that will let an install command like
# nix-env -i -f -A hledger hledger-web hledger-ui
# install the latest available build of the packages, on all platforms of interest.
# These scripts don't seem to quite do that but they help.
NIXARCHS="darwin linux"
HLEDGERPKGS="hledger hledger-ui hledger-web"
# show help for the following commands

intellij-haskell 0.44 notes

intellij-haskell 0.44 feedback

tested with IntelliJ IDEA 2018.3, mac mojave, 2013 macbook air with 8G ram, hledger repo


had to remove alpha plugins repo to see beta 44

installed smoothly in a few minutes (most things probably previously installed)

continuing intermittent errors about starting stack repl taking more than 5s and haskell support not available yet

while building hoogle db ?

turned off power save mode for inspections, and for hlint installation to complete (?)

type signature on hover seemed to work intermittently, was hard to discover

I tried all of these, only the last works, shouldn’t it be just hover ? Or at least, don’t require moving off word
