Makes sense of cross-stage bindings.
Makes sense of cross-stage bindings.
Analysis of cross-stage bindings becomes convenient if we introduce the notion of metalevels. Metalevel of a tree is a number that gets incremented every time you reify something and gets decremented when you splice something. Metalevel of a symbol is equal to the metalevel of its definition.
Example 1. Consider the following snippet:
reify { val x = 2 // metalevel of symbol x is 1, because it's declared inside reify val y = reify{x} // metalevel of symbol y is 1, because it's declared inside reify // metalevel of Ident(x) is 2, because it's inside two reifies y.splice // metalevel of Ident(y) is 0, because it's inside a designator of a splice }
Cross-stage bindings are introduced when symbol.metalevel != curr_metalevel. Both bindings introduced in Example 1 are cross-stage.
Depending on what side of the inequality is greater, the following situations might occur:
1) symbol.metalevel < curr_metalevel. In this case reifier will generate a free variable that captures both the name of the symbol (to be compiled successfully) and its value (to be run successfully). For example, x in Example 1 will be reified as follows: Ident(newFreeVar("x", IntTpe, x))
2) symbol.metalevel > curr_metalevel. This leads to a metalevel breach that violates intuitive perception of splicing. As defined in macro spec, splicing takes a tree and inserts it into another tree - as simple as that. However, how exactly do we do that in the case of y.splice? In this very scenario we can use dataflow analysis and inline it, but what if y were a var, and what if it were calculated randomly at runtime?
This question has a genuinely simple answer. Sure, we cannot resolve such splices statically (i.e. during macro expansion of
reify
), but now we have runtime toolboxes, so noone stops us from picking up that reified tree and evaluating it at runtime (in fact, this is something thatExpr.splice
does transparently).This is akin to early vs late binding dilemma. The prior is faster, plus, the latter (implemented with reflection) might not work because of visibility issues or might be not available on all platforms. But the latter still has its uses, so I'm allowing metalevel breaches, but introducing the -Xlog-runtime-evals to log them.
upd. We no longer do that. In case of a runaway
splice
inside areify
, one will get a static error. Why? Unfortunately, the cute idea of transparently converting between static and dynamic splices has failed. 1) Runtime eval that services dynamic splices requires scala-compiler.jar, which might not be on library classpath 2) Runtime eval incurs a severe performance penalty, so it'd better to be explicit about itAs we can see, the only problem is the fact that lhs'es of
splice
can be code blocks that can capture variables from the outside. Code inside the lhs of ansplice
is not reified, while the code from the enclosing reify is.Hence some bindings become cross-stage, which is not bad per se (in fact, some cross-stage bindings have sane semantics, as in the example above). However this affects freevars, since they are delicate inter-dimensional beings that refer to both current and next planes of existence. When splicing tears the fabric of the reality apart, some freevars have to go single-dimensional to retain their sanity.
Example 2. Consider the following snippet:
reify { val x = 2 reify{x}.splice }
Since the result of the inner reify is wrapped in a splice, it won't be reified together with the other parts of the outer reify, but will be inserted into that result verbatim.
The inner reify produces an Expr[Int] that wraps Ident(freeVar("x", IntTpe, x)). However the freevar the reification points to will vanish when the compiler processes the outer reify. That's why we need to replace that freevar with a regular symbol that will point to reified x.
Example 3. Consider the following fragment:
reify { val x = 2 val y = reify{x} y.splice }
In this case the inner reify doesn't appear next to splice, so it will be reified together with x. This means that no special processing is needed here.
Example 4. Consider the following fragment:
reify { val x = 2 { val y = 2 val z = reify{reify{x + y}} z.splice }.splice }
The reasoning from Example 2 still holds here - we do need to inline the freevar that refers to x. However, we must not touch anything inside the splice'd block, because it's not getting reified.

reifyHighRankList(xs: List[Any])(fill: PartialFunction[Any, tools.nsc.Global.Tree])(fallback: (Any) ⇒ tools.nsc.Global.Tree): tools.nsc.Global.Tree
Reifies list filling all the valid holeMap.
Reifies list filling all the valid holeMap.
Reification of non-trivial list is done in two steps:
- split the list into groups where every placeholder is always put in a group of its own and all subsequent non-holeMap are grouped together; element is considered to be a placeholder if it's in the domain of the fill function;
2. fold the groups into a sequence of lists added together with ++ using fill reification for holeMap and fallback reification for non-holeMap.
Example:
reifyHighRankList(lst) { // first we define patterns that extract high-rank holeMap (currently ..) case Placeholder(IterableType(_, _)) => tree } { // in the end we define how single elements are reified, typically with default reify call reify(_) }
Sample execution of previous concrete list reifier:
> val lst = List(foo, bar, qq$f3948f9s$1) > reifyHighRankList(lst) { ... } { ... } q"List($foo, $bar) ++ ${holeMap(qq$f3948f9s$1).tree}"

state: State
Encapsulates reifier state
Encapsulates reifier state
When untangling reifier symbol tables from the reifier itself, I discovered that encoding of a symbol table (e.g. producing corresponding reificode) might cause subsequent reification (e.g. when filling in signatures and annotations for syms).
This is a mess in the face of nested reifications, splices and inlining of thereof, so I made
SymbolTable
immutable, which brought a significant amount of sanity.However that wasn't enough. Sure, symbol table became immutable, but the reifier still needed to mutate its
symtab
field during reification. This caused nasty desyncs between the table being encoded and the table of the underlying reifier, so I decided to encapsulate the entire state here, so that encoding can backup the state before it starts and restore it after it completes.- Definition Classes

Exposes three main methods: 1)
syms

family of methods that provide information about the symbols in the table, 3)encode
that renders the table into a list of trees (recursively populating #3 and setting up initialization code for #1, #2 and #3)- Definition Classes
