dmd.cond

abstract class Condition: dmd.root.rootobject.RootObject;

class StaticForeach: dmd.root.rootobject.RootObject;

Implements common functionality for StaticForeachDeclaration and StaticForeachStatement This performs the necessary lowerings before dmd.statementsem.makeTupleForeach can be used to expand the corresponding static foreach declaration or statement.

ForeachStatement aggrfe;

Not null iff the static foreach is over an aggregate. In this case, it contains the corresponding ForeachStatement. For StaticForeachDeclaration, the body is null.

ForeachRangeStatement rangefe;

Not null iff the static foreach is over a range. Exactly one of the aggrefe and rangefe fields is not null. See aggrfe field for more details.

bool needExpansion;

true if it is necessary to expand a tuple into multiple variables (see lowerNonArrayAggregate).

final void prepare(Scope* sc);

Perform static foreach lowerings that are necessary in order to finally expand the static foreach using dmd.statementsem.makeTupleForeach.

final bool ready();

Returns:

true iff ready to call dmd.statementsem.makeTupleForeach.

abstract class DVCondition: dmd.cond.Condition;

class DebugCondition: dmd.cond.DVCondition;

deprecated static void addGlobalIdent(const(char)* ident);

static void addGlobalIdent(string ident);

static void addGlobalIdent(const(char)[] ident);

Add an user-supplied identifier to the list of global debug identifiers

Can be called from either the driver or a debug = Ident; statement. Unlike version identifier, there isn't any reserved debug identifier so no validation takes place.

Parameters:

const(char)* ident

identifier to add

this(Module mod, uint level, Identifier ident);

Instantiate a new DebugCondition

Parameters:

Module mod	Module this node belongs to
uint level	Minimum global level this condition needs to pass. Only used if ident is null.
Identifier ident	Identifier required for this condition to pass. If null, this conditiion will use an integer level.

class VersionCondition: dmd.cond.DVCondition;

Node to represent a version condition

A version condition is of the form:

version (Identifier)

In user code. This class also provides means to add version identifier to the list of global (cross module) identifiers.

static void checkReserved(ref const Loc loc, const(char)[] ident);

Raises an error if a version identifier is reserved.

Called when setting a version identifier, e.g. -version=identifier parameter to the compiler or version = Foo in user code.

Parameters:

Loc loc	Where the identifier is set
const(char)[] ident	identifier being checked (ident[$] must be '\0')

deprecated static void addGlobalIdent(const(char)* ident);

static void addGlobalIdent(string ident);

static void addGlobalIdent(const(char)[] ident);

Add an user-supplied global identifier to the list

Only called from the driver for -version=Ident parameters. Will raise an error if the identifier is reserved.

Parameters:

const(char)* ident

identifier to add

deprecated static void addPredefinedGlobalIdent(const(char)* ident);

static void addPredefinedGlobalIdent(string ident);

static void addPredefinedGlobalIdent(const(char)[] ident);

Add any global identifier to the list, without checking if it's predefined

Only called from the driver after platform detection, and internally.

Parameters:

const(char)* ident

identifier to add (ident[$] must be '\0')

this(Module mod, uint level, Identifier ident);

Instantiate a new VersionCondition

Parameters:

Module mod	Module this node belongs to
uint level	Minimum global level this condition needs to pass. Only used if ident is null.
Identifier ident	Identifier required for this condition to pass. If null, this conditiion will use an integer level.

class StaticIfCondition: dmd.cond.Condition;

bool findCondition(Identifiers* ids, Identifier ident);

Find ident in an array of identifiers.

Parameters:

Identifiers* ids	array of identifiers
Identifier ident	identifier to search for

Returns:

true if found
