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 "learn Haskell"
  
  -- syntax: task "keyword: dependencies" io-action
  task "learn-haskell: learn-fp" (putStrLn "Haskell is awesome!")

  desc "learn Functional Programming"
  task "learn-fp: learn-lisp" $ do
    sh "echo 'into FP'"

  desc "learn LISP"
  task "learn-lisp" $ do
    sh "echo 'LISP is cool!'"

run nemesis

It will generate a bin .nemesis inside your current folder.

Run

run ./.nemesis

     learn-fp: learn Functional Programming
learn-haskell: learn Haskell
   learn-lisp: learn LISP

run ./.nemesis learn-haskell

LISP is cool!
into FP
Haskell is awesome!

Namespace

Suppose you have the following tasks

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.

Hint

Save typing by aliasing ./.nemesis to n, i.e. inside .your_shellrc

alias n="./.nemesis"
