Exported datatypes:

Version

A Version. Tuple components are major, minor, patch, prerelease, e.g. 3.1.1-rc5

Type synonym: Version = (Int,Int,Int,Maybe String)

Conjunction

Type synonym: Conjunction = [VersionConstraint]

Disjunction

Type synonym: Disjunction = [Conjunction]

Dependency

A dependency on another package. The disjunctive normal form of a boolean combination of version constraints is represented by a list of lists of version constraint. Each inner list of version constraints is a conjunction, the outer list is a disjunction.

Constructors:

VersionConstraint

A version constraint.

Constructors:

  • VExact :: Version -> VersionConstraint : versions must match exactly
  • VGt :: Version -> VersionConstraint : version must be strictly larger than specified version
  • VLt :: Version -> VersionConstraint : version must be strictly smaller than specified version
  • VGte :: Version -> VersionConstraint : version must be larger or equal to specified version
  • VLte :: Version -> VersionConstraint : version must be smaller or equal to specified version
  • VCompatible :: Version -> VersionConstraint : semver arrow, version must be larger or equal and within same minor version
CompilerCompatibility

Compiler compatibility constraint, takes the name of the compiler (kics2 or pakcs), as well as a disjunctive normal form combination of version constraints (see Dependency).

Constructors:

  • CompilerCompatibility :: String -> Disjunction -> CompilerCompatibility
PackageId

A package id consisting of the package name and version.

Constructors:

  • PackageId :: String -> Version -> PackageId
PackageExecutable

The specification to generate an executable from the package. It consists of the name of the executable, the name of the main module (which must contain an operation main), and list of options for various compilers (i.e., pairs of compiler name and options for this compiler).

Constructors:

  • PackageExecutable :: String -> String -> [(String,String)] -> PackageExecutable
PackageTest

The specification of a single test suite for a package. It consists of a directory, a list of modules, options (for CurryCheck), and a name of a test script in this directory. The test script can be empty, but then a non-empty list of modules must be provided. This structure specifies a test which is performed in the given directory by running CurryCheck on the given list of modules where the option string is passed to CurryCheck.

Constructors:

  • PackageTest :: String -> [String] -> String -> String -> PackageTest
PackageDocumentation

The specification to generate the documentation of the package. It consists of the name of the directory containing the documentation, a main file (usually, a LaTeX file) containing the documentation, and a command to generate the documentation. If the command is missing and the main file has the suffix "tex", e.g., "manual.tex", the default command is "pdflatex manual.tex".

Constructors:

  • PackageDocumentation :: String -> String -> String -> PackageDocumentation
PackageSource

A source where the contents of a package can be acquired.

Constructors:

  • Http :: String -> PackageSource : URL to a ZIP file
  • Git :: String -> (Maybe GitRevision) -> PackageSource : URL to a Git repository and an optional revision spec to check out
  • FileSource :: String -> PackageSource : The path to a ZIP file to install. Cannot be specified in a package specification file, for internal use only.
GitRevision

A Git revision.

Constructors:

  • Tag :: String -> GitRevision : A tag which might contain the string $version$ which will be replaced by the package version
  • Ref :: String -> GitRevision : A Git commitish, i.e. a SHA, a branch name, a tag name etc.
  • VersionAsTag :: GitRevision : Use the package version prefixed with a v as the tag
Package

The data type for package specifications.

Constructors:

  • Package :: String -> Version -> String -> (Maybe String) -> String -> (Maybe String) -> [String] -> (Maybe String) -> (Maybe String) -> (Maybe String) -> (Maybe String) -> (Maybe String) -> (Maybe String) -> [Dependency] -> [CompilerCompatibility] -> (Maybe PackageSource) -> [String] -> [String] -> (Maybe String) -> (Maybe PackageExecutable) -> (Maybe [PackageTest]) -> (Maybe PackageDocumentation) -> Package
