Demo

import System.Nemesis

main = run $ 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

Create a file named Nemesis

import System.Nemesis
import System.Nemesis.Utils ((-))
import Prelude hiding ((-))

main = run - do

  -- desc is optional, it gives some description to the task
  -- task syntax: task "keyword: space seperated dependencies" io-action
  desc "Hunter attack macro"
  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

runghc Nemesis

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

runghc Nemesis attack

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

Namespace

Create namespaces for tasks with the keyword namespace

import System.Nemesis
import System.Nemesis.Utils ((-))
import Prelude hiding ((-))

main = run - do

  namespace "eat" - do

    task "bread: salad" - putStrLn "eating bread"
    task "salad: /drink/coke" - putStrLn "eating salad"


  namespace "drink" - do

    task "coke" - putStrLn "drinking coke"

Namespaces are referenced as path components.

runghc Nemesis bread

Nemesis: bread does not exist!

runghc Nemesis eat/bread

drinking coke
eating salad
eating bread

Hints

  • alias runghc Nemesis to something sweeter, e.g. n
