Minimal complete definition

Nothing

class HasStackRoot env where Source

Class for environment values which have access to the stack root

Minimal complete definition

Nothing

Methods

Config & HasConfig

data Config Source

The top-level Stackage configuration.

Constructors

Config 

Fields

configStackRoot :: !(Path Abs Dir)

~/.stack more often than not

configWorkDir :: !(Path Rel Dir)

this allows to override .stack-work directory

configUserConfigPath :: !(Path Abs File)

Path to user configuration file (usually ~.stackconfig.yaml)

configDocker :: !DockerOpts

Docker configuration

configNix :: !NixOpts

Execution environment (e.g nix-shell) configuration

configEnvOverride :: !(EnvSettings -> IO EnvOverride)

Environment variables to be passed to external tools

configLocalProgramsBase :: !(Path Abs Dir)

Non-platform-specific path containing local installations

configLocalPrograms :: !(Path Abs Dir)

Path containing local installations (mainly GHC)

configConnectionCount :: !Int

How many concurrent connections are allowed when downloading

configHideTHLoading :: !Bool

Hide the Template Haskell "Loading package ..." messages from the console

configPlatform :: !Platform

The platform we're building for, used in many directory names

configPlatformVariant :: !PlatformVariant

Variant of the platform, also used in directory names

configGHCVariant0 :: !(Maybe GHCVariant)

The variant of GHC requested by the user. In most cases, use BuildConfig or MiniConfigs version instead, which will have an auto-detected default.

configLatestSnapshotUrl :: !Text

URL for a JSON file containing information on the latest snapshots available.

configPackageIndices :: ![PackageIndex]

Information on package indices. This is left biased, meaning that packages in an earlier index will shadow those in a later index.

Warning: if you override packages in an index vs what's available upstream, you may correct your compiled snapshots, as different projects may have different definitions of what pkg-ver means! This feature is primarily intended for adding local packages, not overriding. Overriding is better accomplished by adding to your list of packages.

Note that indices specified in a later config file will override previous indices, not extend them.

Using an assoc list instead of a Map to keep track of priority

configSystemGHC :: !Bool

Should we use the system-installed GHC (on the PATH) if available? Can be overridden by command line options.

configInstallGHC :: !Bool

Should we automatically install GHC if missing or the wrong version is available? Can be overridden by command line options.

configSkipGHCCheck :: !Bool

configCompilerCheck :: !VersionCheck

Specifies which versions of the compiler are acceptable.

configLocalBin :: !(Path Abs Dir)

Directory we should install executables into

configRequireStackVersion :: !VersionRange

Require a version of stack within this range.

configJobs :: !Int

How many concurrent jobs to run, defaults to number of capabilities

configExtraIncludeDirs :: !(Set Text)
  • -extra-include-dirs arguments
configExtraLibDirs :: !(Set Text)
  • -extra-lib-dirs arguments
configConfigMonoid :: !ConfigMonoid
