Nemesis: a task management tool for Haskell
Demo
import System.Nemesis.Env
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.Env
import Air.Env ((-))
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.Env
import Air.Env ((-))
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
