Nemesis: a rake like task management tool for haskell

Demo

nemesis = do

  clean
    [ "**/*.hi"
    , "**/*.o"
    , "manifest"
    ]
    
  task "dist" $ do
    sh "cabal clean"
    sh "cabal configure"
    sh "cabal sdist"

  task "i" (sh "ghci -isrc src/System/Nemesis.hs")

  task "manifest" $ do
    sh "find . | grep 'hs$' > manifest"

Tutorial

Install

cabal update; cabal install nemesis

DSL

Put the following code into a file named Nemesis

nemesis = do

  -- desc is optional, it gives some description to the following task
  desc "Hunter attack macro"

  -- syntax: task "keyword: dependencies" io-action
  task "attack: pet-attack auto-attack" (putStrLn "attack macro done!")

  desc "Pet attack"
  task "pet-attack: mark" $ do
    sh "echo 'pet attack'"

  desc "Hunter's mark"
  task "mark" $ do
    sh "echo \"casting hunter's mark\""

  desc "Auto attack"
  task "auto-attack" $ do
    sh "echo 'auto shoot'"

Run

run nemesis

attack                            : Hunter attack macro
auto-attack                       : Auto attack
mark                              : Hunter's mark
pet-attack                        : Pet attack

run nemesis attack

casting hunter's mark
pet attack
auto shoot
attack macro done!

Namespace

Suppose you have the following tasks

nemesis = do

  namespace "eat" $ do

    task "bread: salad" $ putStrLn "eating bread"
    task "salad: /drink/coke" $ putStrLn "nice salad"


  namespace "drink" $ do

    task "coke" $ putStrLn "drinking coke"

then

nemesis bread =>
.nemesis: bread does not exist!

nemesis eat/bread =>
drinking coke
nice salad
eating bread

Advance usage

Use LANGUAGE

Use a separator below language extensions, e.g.

{-# LANGUAGE QuasiQuotes #-}

-- Nem

nemesis = do
  task "i" (sh "ghci -isrc src/System/Nemesis.hs")

currently the separator -- Nem is hard coded

Build it yourself

If you don't want nemesis to compile Nemesis through intermediate nemesis-tmp.hs file, rename your Nemesis to Nemesis.hs, then start with this template.

import System.Nemesis (run)
import System.Nemesis.DSL

nemesis = do
  task "i" (sh "ghci -isrc src/System/Nemesis.hs")
    
main = run nemesis

The logic is that whenever main is defined in Nemesis.hs, nemesis will act as ghc --make wrapper, so you can get nice error messages.

That's it!
