stack- The Haskell Tool Stack

Safe HaskellNone



The general Stack configuration that starts everything off. This should be smart to falback if there is no stack.yaml, instead relying on whatever files are available.

If there is no stack.yaml, and there is a cabal.config, we read in those constraints, and if there's a cabal.sandbox.config, we read any constraints from there and also find the package database from there, etc. And if there's nothing, we should probably default to behaving like cabal, possibly with spitting out a warning that "you should run `stk init` to make things better".



loadConfig Source


:: (MonadLogger m, MonadIO m, MonadCatch m, MonadThrow m, MonadBaseControl IO m, MonadReader env m, HasHttpManager env, HasTerminal env) 
=> ConfigMonoid

Config monoid from parsed command-line arguments

-> Maybe (Path Abs File)

Override stack.yaml

-> Maybe AbstractResolver

Override resolver

-> m (LoadConfig m) 

Load the configuration, using current directory, environment variables, and defaults as necessary.

resolvePackageEntry Source


:: (MonadIO m, MonadThrow m, MonadReader env m, HasHttpManager env, MonadLogger m, MonadCatch m, MonadBaseControl IO m, HasConfig env) 
=> EnvOverride 
-> Path Abs Dir

project root

-> PackageEntry 
-> m [(Path Abs Dir, Bool)] 

Resolve a PackageEntry into a list of paths, downloading and cloning as necessary.

getImplicitGlobalProjectDir :: (MonadIO m, MonadLogger m) => Config -> m (Path Abs Dir) Source

Get the location of the implicit global project directory. If the directory already exists at the deprecated location, its location is returned. Otherwise, the new location is returned.
