download: installing on arch...

[pangoSE]

I tried installing on Arch and tried to document my efforts for the benefit of others interesting in a stable hledger install.
I recommend adding the following to the download-page:

On arch install the stable version with
sudo pacman -S stack ghc && stack setup && stack install --resolver=nightly hledger hledger-ui hledger-web
or the dev-version via the AUR-package hledger-git

---

Running "stack setup" produces an error if GHC is not installed already.

   $ stack setup
  Run from outside a project, using implicit global project config
  Using resolver: lts-7.9 from implicit global project's config file: /home/egil/.stack/global-project/stack.yaml
  Unable to find installation URLs for OS key: linux32-ncurses6

Thanks! Do you know if the stack setup failure has been reported to the stack tracker ?

There is a question about whether to include stack setup in the command line. We recently removed it from the source instructions, instead saying "run stack setup if stack install tells you to", because doing it preemptively that way won't necessarily get you the required GHC version, so the user would get another request to run stack setup and have to do it a second time (or something like that, there was confusion).

Plus, since you have installed ghc with pacman, won't stack install use it automatically, requiring no stack setup step ?

I will add hledger-api to the command line, unless there's some reason you left it out.

And... hmm, this command does not install a packaged version, so probably doesn't belong in the top section. Perhaps it should be mentioned somewhere in the installing from source section.

Linked this issue from B1.

@egils-verkstad, @mstksg, Arch users: do you think the "On Arch, you may need to also install GHC manually" note is still needed at http://hledger.org/download.html#b ?
