Types for project config
data ProjectConfig Source #
This type corresponds directly to what can be written in the
cabal.project file. Other sources of configuration can also be injected
into this type, such as the user-wide config file and the
command line of cabal configure or cabal build.
Since it corresponds to the external project file it is an instance of
Monoid and all the fields can be empty. This also means there has to
be a step where we resolve configuration. At a minimum resolving means
applying defaults but it can also mean merging information from multiple
sources. For example for package-specific configuration the project file
can specify configuration that applies to all local packages, and then
additional configuration for a specific package.
Future directions: multiple profiles, conditionals. If we add these features then the gap between configuration as written in the config file and resolved settings we actually use will become even bigger.
Constructors

newtype ProjectConfigToParse Source #
The project configuration is configuration that is parsed but parse configuration may import more configuration. Holds the unparsed contents of an imported file contributing to the project config.
Constructors

data ProjectConfigBuildOnly Source #
That part of the project configuration that only affects how we build and not the value of the things we build. This means this information does not need to be tracked for changes since it does not affect the outcome.

data ProjectConfigProvenance Source #
Specifies the provenance of project configuration, whether defaults were used or if the configuration was read from an explicit file path.

| -> Maybe FilePath | Explicit project file |
| -> IO (Either BadProjectRoot ProjectRoot) |
Find the root of this project.
The project directory will be one of the following:
1. mprojectDir when present
2. The first directory containing mprojectFile/cabal.project, starting from the current directory
and recursively checking parent directories
3. The current directory
getProjectRootUsability :: FilePath -> IO ProjectRootUsability Source #
Get ProjectRootUsability of a given file
data ProjectRoot Source #
Information about the root directory of the project.
It can either be an implicit project root in the current dir if no
cabal.project file is found, or an explicit root if either
the file is found or the project root directory was specified.

Project config files
Arguments
| :: Verbosity | |
| -> HttpTransport | |
| -> Flag Bool | --ignore-project |
| -> Flag FilePath | |
| -> DistDirLayout | |
| -> Rebuild ProjectConfigSkeleton |
Read all the config relevant for a project. This includes the project file if any, plus other global config.
readGlobalConfig :: Verbosity -> Flag FilePath -> Rebuild ProjectConfig Source #
Read the user's cabal-install config file.
readProjectLocalExtraConfig :: Verbosity -> HttpTransport -> DistDirLayout -> Rebuild ProjectConfigSkeleton Source #
Reads a cabal.project.local file in the given project root dir,
or returns empty. This file gets written by cabal configure, or in
principle can be edited manually or by other tools.
readProjectLocalFreezeConfig :: Verbosity -> HttpTransport -> DistDirLayout -> Rebuild ProjectConfigSkeleton Source #
Reads a cabal.project.freeze file in the given project root dir,
or returns empty. This file gets written by cabal freeze, or in
principle can be edited manually or by other tools.
reportParseResult :: Verbosity -> String -> FilePath -> ParseResult ProjectConfigSkeleton -> IO ProjectConfigSkeleton Source #
showProjectConfig :: ProjectConfig -> String Source #
Render the ProjectConfig format.
For the moment this is implemented in terms of a pretty printer for the legacy configuration types, plus a conversion.
writeProjectLocalExtraConfig :: DistDirLayout -> ProjectConfig -> IO () Source #
Write a cabal.project.local file in the given project root dir.
writeProjectLocalFreezeConfig :: DistDirLayout -> ProjectConfig -> IO () Source #
Write a cabal.project.freeze file in the given project root dir.
writeProjectConfigFile :: FilePath -> ProjectConfig -> IO () Source #
Write in the cabal.project format to the given file.
commandLineFlagsToProjectConfig :: GlobalFlags -> NixStyleFlags a -> ClientInstallFlags -> ProjectConfig Source #
Convert configuration from the cabal configure or cabal build command
line into a ProjectConfig value that can combined with configuration from
other sources.
At the moment this uses the legacy command line flag types. See
LegacyProjectConfig for an explanation.
onlyTopLevelProvenance :: Set ProjectConfigProvenance -> Set ProjectConfigProvenance Source #
Filter out non-top-level project configs.
Packages within projects
data ProjectPackageLocation Source #
The location of a package as part of a project. Local file paths are either absolute (if the user specified it as such) or they are relative to the project root.
Constructors

| Show ProjectPackageLocation Source # | |
Defined in Distribution.Client.ProjectConfig Methods showsPrec :: Int -> ProjectPackageLocation -> ShowS # show :: ProjectPackageLocation -> String # showList :: [ProjectPackageLocation] -> ShowS # | |

findProjectPackages :: DistDirLayout -> ProjectConfig -> Rebuild [ProjectPackageLocation] Source #
Determines the location of all packages mentioned in the project configuration.
Throws BadPackageLocations.
fetchAndReadSourcePackages :: Verbosity -> DistDirLayout -> ProjectConfigShared -> ProjectConfigBuildOnly -> [ProjectPackageLocation] -> Rebuild [PackageSpecifier (SourcePackage UnresolvedPkgLoc)] Source #
Read the .cabal files for a set of packages. For remote tarballs and
VCS source repos this also fetches them if needed.
Note here is where we convert from project-root relative paths to absolute paths.
Resolving configuration
lookupLocalPackageConfig :: (Semigroup a, Monoid a) => (PackageConfig -> a) -> ProjectConfig -> PackageName -> a Source #
Look up a PackageConfig field in the ProjectConfig for a specific
PackageName. This returns the configuration that applies to all local
packages plus any package-specific configuration for this package.
projectConfigWithBuilderRepoContext :: Verbosity -> BuildTimeSettings -> (RepoContext -> IO a) -> IO a Source #
Use a RepoContext based on the BuildTimeSettings.
projectConfigWithSolverRepoContext :: Verbosity -> ProjectConfigShared -> ProjectConfigBuildOnly -> (RepoContext -> IO a) -> IO a Source #
Use a RepoContext, but only for the solver. The solver does not use the
full facilities of the RepoContext so we can get away with making one
that doesn't have an http transport. And that avoids having to have access
to the BuildTimeSettings
data SolverSettings Source #
Resolved configuration for the solver. The idea is that this is easier to
use than the raw configuration because in the raw configuration everything
is optional (monoidial). In the BuildTimeSettings every field is filled
in, if only with the defaults.
Use resolveSolverSettings to make one from the project config (by
applying defaults etc).
Constructors
Instances
resolveSolverSettings :: ProjectConfig -> SolverSettings Source #
Resolve the project configuration, with all its optional fields, into
SolverSettings with no optional fields (by applying defaults).
data BuildTimeSettings Source #
Resolved configuration for things that affect how we build and not the
value of the things we build. The idea is that this is easier to use than
the raw configuration because in the raw configuration everything is
optional (monoidial). In the BuildTimeSettings every field is filled in,
if only with the defaults.
Use resolveBuildTimeSettings to make one from the project config (by
applying defaults etc).
Constructors
resolveBuildTimeSettings :: Verbosity -> CabalDirLayout -> ProjectConfig -> BuildTimeSettings Source #
Resolve the project configuration, with all its optional fields, into
BuildTimeSettings with no optional fields (by applying defaults).
Checking configuration
checkBadPerPackageCompilerPaths :: [ConfiguredProgram] -> Map PackageName PackageConfig -> IO () Source #
The project configuration is not allowed to specify program locations for programs used by the compiler as these have to be the same for each set of packages.
We cannot check this until we know which programs the compiler uses, which in principle is not until we've configured the compiler.
Throws BadPerPackageCompilerPaths
data BadPerPackageCompilerPaths Source #
Constructors
| BadPerPackageCompilerPaths [(PackageName, String)] |
Instances
| Exception BadPerPackageCompilerPaths Source # | |
| Show BadPerPackageCompilerPaths Source # | |
Defined in Distribution.Client.ProjectConfig Methods showsPrec :: Int -> BadPerPackageCompilerPaths -> ShowS # show :: BadPerPackageCompilerPaths -> String # showList :: [BadPerPackageCompilerPaths] -> ShowS # | |
