Dependency

Represents a dependency specification.

A dependency specification either represents a specific version or version range, or a path to a package. In addition to that it has optional and default_ flags to control how non-mandatory dependencies are handled. The package name is notably not part of the dependency specification.

Constructors

this this(string spec): Constructs a new dependency specification from a string
this this(Version ver): Constructs a new dependency specification that matches a specific version.
this this(NativePath path): Constructs a new dependency specification that matches a specific path.
this this(Repository repository, string spec): Constructs a new dependency specification that matches a specific Git reference.

Functions

mapToPath Dependency mapToPath(NativePath path): Returns a modified dependency that gets mapped to a given path.
matches bool matches(const(Version) v): Tests if the specification matches a specific version.
matches bool matches(string vers): Tests if the specification matches a specific version.
matchesAny bool matchesAny(): Determines if this dependency specification matches arbitrary versions.
merge Dependency merge(const(Dependency) o): Merges two dependency specifications.
opCmp int opCmp(Dependency o): Compares dependency specifications.
opEquals bool opEquals(Dependency o)
toHash size_t toHash(): Compares dependency specifications.
toJson Json toJson(): Returns a JSON representation of the dependency specification.
toString string toString(): Returns a human-readable string representation of the dependency specification.
valid bool valid(): Determines if this dependency specification is valid.

Properties

any Dependency any [@property getter]: A Dependency, which matches every valid version.
default_ bool default_ [@property getter]
bool default_ [@property setter]: Determines if an optional dependency should be chosen by default.
invalid Dependency invalid [@property getter]: An invalid dependency (with no possible version matches).
isExactVersion bool isExactVersion [@property getter]: Returns true iff the version range only matches a specific version.
isSCM bool isSCM [@property getter]: Determines whether it is a Git dependency.
optional bool optional [@property getter]
bool optional [@property setter]: Determines if the dependency is required or optional.
path NativePath path [@property setter]
NativePath path [@property getter]: If set, overrides any version based dependency selection.
repository Repository repository [@property setter]
Repository repository [@property getter]: If set, overrides any version based dependency selection.
versionSpec string versionSpec [@property setter]
string versionSpec [@property getter]: Sets/gets the matching version range as a specification string.
version_ Version version_ [@property getter]: Returns the exact version matched by the version range.

Static functions

fromJson Dependency fromJson(Json verspec): Constructs a new Dependency from its JSON representation.
