class Context extends AnyRef
A motley collection of the state and loosely associated behaviour of the type checker.
A motley collection of the state and loosely associated behaviour of the type checker. Each Typer has an associated context, and as it descends into the tree new (Typer, Context) pairs are spawned.
Meet the crew; first the state:
- A tree, symbol, and scope representing the focus of the typechecker
- An enclosing context, outer.
- The current compilation unit.
- A variety of bits that track the current error reporting policy (more on this later); whether or not implicits/macros are enabled, whether we are in a self or super call or in a constructor suffix. These are represented as bits in the mask contextMode.
- Some odds and ends: undetermined type parameters of the current line of type inference; contextual augmentation for error messages, tracking of the nesting depth.
And behaviour:
- The central point for issuing errors and warnings from the typechecker, with a means to buffer these for use in 'silent' type checking, when some recovery might be possible.
- Context is something of a Zipper for the tree were are typechecking: it enclosingContextChain is the path back to the root. This is exactly what we need to resolve names (lookupSymbol) and to collect in-scope implicit definitions (implicitss) Supporting these are imports, which represents all Import trees in in the enclosing context chain.
- In a similar vein, we can assess accessibility (isAccessible.)
More on error buffering: When are type errors recoverable? In quite a few places, it turns out. Some examples: trying to type an application with/without the expected type, or with/without implicit views enabled. This is usually mediated by Typer.silent, Inferencer#tryTwice.
Initially, starting from the typer phase, the contexts either buffer or report errors; afterwards errors are thrown. This is configured in rootContext. Additionally, more fine grained control is needed based on the kind of error; ambiguity errors are often suppressed during exploratory typing, such as determining whether a == b in an argument position is an assignment or a named argument, when Inferencer#isApplicableSafe type checks applications with and without an expected type, or when Typer#tryTypedApply tries to fit arguments to a function type with/without implicit views.
When the error policies entail error/warning buffering, the mutable ContextReporter records everything that is issued. It is important to note, that child Contexts created with make "inherit" the very same ContextReporter instance, whereas children spawned through makeSilent receive a separate, fresh buffer.
Definition Classes
Contexts
abstract class ContextReporter extends AnyRef
A reporter for use during type checking.
A reporter for use during type checking. It has multiple modes for handling errors.
The default (immediate mode) is to send the error to the global reporter. When switched into buffering mode via makeBuffering, errors and warnings are buffered and not be reported (there's a special case for ambiguity errors for some reason: those are force to the reporter when context.ambiguousErrors, or else they are buffered -- TODO: can we simplify this?)
When using the type checker after typers, an error results in a TypeError being thrown. TODO: get rid of this mode.
To handle nested contexts, reporters share buffers. TODO: only buffer in BufferingReporter, emit immediately in ImmediateReporter

Macro expansion
First of all macroExpandXXX: 1) If necessary desugars the expandee to fit into the default expansion scheme that is understood by macroExpandWithRuntime / macroExpandWithoutRuntime
Then macroExpandWithRuntime: 2) Checks whether the expansion needs to be delayed 3) Loads macro implementation using macroMirror 4) Synthesizes invocation arguments for the macro implementation 5) Checks that the result is a tree or an expr bound to this universe
Finally macroExpandXXX: 6) Validates the expansion against the white list of supported tree shapes 7) Typechecks the result as required by the circumstances of the macro application
If -Ymacro-debug-lite is enabled, you will get basic notifications about macro expansion along with macro expansions logged in the form that can be copy/pasted verbatim into REPL.
If -Ymacro-debug-verbose is enabled, you will get detailed log of how exactly this function performs class loading and method resolution in order to load the macro implementation. The log will also include other non-trivial steps of macro expansion.
returns

There are two key methods in here.
1) Enter methods such as enterGetterSetter are called from Namer with a tree which may generate further trees such as accessors or implicit wrappers. Some setup is performed. In general this creates symbols and enters them into the scope of the owner.
2) addDerivedTrees is called from Typer when a Template is typed. It completes the job, returning a list of trees with their symbols set to those created in the enter methods. Those trees then become part of the typed template.

Marks a tree that has been adapted by typer and sets the original tree that was in place before.
Keeping track of the original trees were is an important feature for some compiler plugins (like Scalameta) and the incremental compiler (Zinc). In both cases, adapting trees loses information in some sense and do not allow external tools to capture some information stored in user-defined trees that are optimized away by early phases (mostly, typer).
See how the absence of this attachment blocks Zinc: https://github.com/sbt/zinc/issues/227. Related: https://github.com/scala/scala-dev/issues/340.
This attachment is, at the moment, only used to keep track of constant-folded constants. It has a generic wording in the hope that in the future can be reused in the same context to keep track of other adapted trees.

def caseClassCopyMeth(cdef: Global.ClassDef): Option[Global.DefDef]
Generates copy methods for case classes.
Generates copy methods for case classes. Copy only has defaults on the first parameter list, as of scala/bug#5009.
The parameter types of the copy method need to be exactly the same as the parameter types of the primary constructor. Just copying the TypeTree is not enough: a type C might refer to something else *inside* the class (i.e. as parameter type of copy) than *outside* the class (i.e. in the class parameter list).
One such example is t0054.scala: class A { case class B(x: C) extends A { def copy(x: C = x) = ... } class C {} } (1) (2)
The reference (1) to C is A.this.C. The reference (2) is B.this.C - not the same.
This is fixed with a hack currently. Unapplies.caseClassCopyMeth, which creates the copy method, uses empty TypeTree() nodes for parameter types.
In Namers.enterDefDef, the copy method gets a special type completer (enterCopyMethod). Before computing the body type of copy, the class parameter types are assigned the copy method parameters.
This attachment class stores the copy method parameter ValDefs as an attachment in the ClassDef of the case class.

{
  private synthetic val eta$f   = p.f   // if p is not stable
  ...
  private synthetic val eta$e_i = e_i   // if e_i is not stable
  ...
  (ps_1 => ... => ps_m => eta$f([es_1])...([es_m])(ps_1)...(ps_m))
}
```
This is called from typedEtaExpansion, which itself is called from
- instantiateToMethodType (for a naked method reference), or
- typedEta (when type checking a method value, m _).

Without any restrictions on macro expansion, macro applications will expand at will, and when type inference is involved, expansions will end up using yet uninferred type params.
Without any restrictions on macro expansion, macro applications will expand at will, and when type inference is involved, expansions will end up using yet uninferred type params.
For some macros this might be ok (thanks to TreeTypeSubstituter that replaces the occurrences of undetparams with their inferred values), but in general case this won't work. E.g. for reification simple substitution is not enough - we actually need to re-reify inferred types.
Luckily, there exists a very simple way to fix the problem: delay macro expansion until everything is inferred. Here are the exact rules. Macro application gets delayed if any of its subtrees contain: 1) type vars (tpe.isInstanceOf[TypeVar]) // [Eugene] this check is disabled right now, because TypeVars seem to be created from undetparams anyways 2) undetparams (sym.isTypeParameter && !sym.isSkolem)

def transformNamedApplication(typer: Typer, mode: Mode, pt: Global.Type)(tree: Global.Tree, argPos: (Int) => Int): Global.Tree
Transform a function application into a Block, and assigns typer.context .namedApplyBlockInfo to the new block as side-effect.
Transform a function application into a Block, and assigns typer.context .namedApplyBlockInfo to the new block as side-effect. If tree has the form Apply(fun, args) first the function "fun" (which might be an application itself!) is transformed into a block of the form { val qual$1 = qualifier_of_fun val x$1 = arg_1_of_fun ... val x$n = arg_n_of_fun qual$1.fun[targs](x$1, ...)...(..., x$n) } then for each argument in args, a value is created and entered into the block. finally the application expression of the block is updated. { val qual$1 = .. ... val x$n = ... > val qual$n+1 = arg(1) > ... > val qual$n+m = arg(m) > qual$1.fun[targs](x$1, ...)...(..., x$n)(x$n+1, ..., x$n+m) }
typer
the typer calling this method; this method calls typer.doTypedApply
mode
the mode to use for calling typer.doTypedApply
pt
the expected type for calling typer.doTypedApply
tree
the function application tree
argPos
a function mapping arguments from their current position to the position specified by the method type. example: def foo(a: Int, b: String) foo(b = "1", a = 2) calls transformNamedApplication(Apply(foo, List("1", 2), { 0 => 1, 1 => 0 })
returns
the transformed application (a Block) together with the NamedApplyInfo. if isNamedApplyBlock(tree), returns the existing context.namedApplyBlockInfo

def transformTypeTagEvidenceParams(macroImplRef: Global.Tree, transform: (Global.Symbol, Global.Symbol) => Global.Symbol): List[List[Global.Symbol]]
Transforms parameters lists of a macro impl.
Transforms parameters lists of a macro impl. The transform function is invoked only for WeakTypeTag evidence parameters.
The transformer takes two arguments: a value parameter from the parameter list and a type parameter that is witnesses by the value parameter.
If the transformer returns a NoSymbol, the value parameter is not included from the result. If the transformer returns something else, this something else is included in the result instead of the value parameter.
Despite of being highly esoteric, this function significantly simplifies signature analysis. For example, it can be used to strip macroImpl.paramss from the evidences (necessary when checking def <-> impl correspondence) or to streamline creation of the list of macro arguments.
