NvFetcher

The main module of nvfetcher. If you want to create CLI program with it, it's enough to import only this module.

Example:

module Main where

import NvFetcher

main :: IO ()
main = defaultMain defaultArgs packageSet

packageSet :: PackageSet ()
packageSet = do
  define $ package "feeluown-core" fromPypi "feeluown"
  define $ package "qliveplayer" fromGitHub (IsoaSFlus, QLivePlayer)

You can find more examples of packages in Main_example.hs.

Running the created program:

• main -- abbreviation of main build
• main build -- build nix sources expr from given packageSet
• main clean -- delete .shake dir and generated nix file
• main -j -- build with parallelism

All shake options are inherited.
