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 = runNvFetcher packageSet

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

All shake options are inherited.

runNvFetcher :: PackageSet () -> IO ()

Run nvfetcher with CLI options

This function calls runNvFetcherNoCLI, using def Config overridden by CLIOptions. Use this function to create your own Haskell executable program.

runNvFetcher' :: Config -> PackageSet () -> IO ()

Similar to runNvFetcher, but uses custom config instead of def overridden by CLIOptions

runNvFetcherNoCLI :: Config -> Target -> PackageSet () -> IO ()

Entry point of nvfetcher

applyCliOptions :: Config -> CLIOptions -> IO Config

Apply CLIOptions to Config
