ILAst Pattern Matching |
||||
================= |
||||
|
||||
Some IL instructions are classified as "patterns". |
||||
```c# |
||||
abstract class PatternMatchILInstruction : IStoreInstruction { |
||||
public ILInstruction TestedOperand { get; } |
||||
public ILVariable Variable { get; } // variable that receives the match result; may also be a temporary |
||||
} |
||||
|
||||
public bool IsPattern(this ILInstruction inst, out ILInstruction testedOperand) => inst switch { |
||||
PatternMatchILInstruction pm => testedOperand = pm.TestedOperand; return true; |
||||
LogicNot logicNot => IsPattern(logicNot.Operand, out testedOperand), |
||||
Comp comp => testedOperand = comp.Left; return IsConstant(comp.Right); |
||||
} |
||||
``` |
||||
Every `match.*` instruction has the following properties: |
||||
* The `TestedOperand` specifies what gets matched against the pattern. |
||||
* The `Variable` stores the value of `TestedOperand` (after converting to the matched type, if appropriate). |
||||
* If this variable is also used outside the `match.*` node, it corresponds to the C# `single_variable_designation`. |
||||
* Otherwise it's a temporary used for pattern matching. |
||||
* I think in both cases it should have VariableKind.PatternVar |
||||
* The match instruction evaluates to `StackType.I4`: 0 if the pattern was matched, 1 otherwise. |
||||
|
||||
Some `match` instructions have a body with `List<ILInstruction> nestedPatterns`. Here every nested pattern must be a pattern according to `IsPattern()`, and the `testedOperand` of each must be a member of the `Variable` of the parent pattern. (members are: field, property, or deconstruction.result). |
||||
(exception: `match.and`/`match.or`, these instead require the `testedOperand` to be exactly the `Variable` of the parent pattern) |
||||
|
||||
|
||||
Examples |
||||
-------- |
||||
1) `expr is var x` |
||||
=> |
||||
`match.var(x = expr)` |
||||
=> |
||||
``` |
||||
Block (VarPattern) { |
||||
stloc x(expr) // single eval expr |
||||
final: ldc.i4 1 // match always |
||||
} |
||||
``` |
||||
2) `expr is T x` |
||||
=> |
||||
`match.type T(x = expr) {}` |
||||
=> |
||||
``` |
||||
Block (TypePattern) { |
||||
stloc x(isinst T(expr)) |
||||
final: x != null |
||||
} |
||||
``` |
||||
3) `expr is C { A: var x } z` |
||||
=> |
||||
``` |
||||
match.type C(z = expr) { |
||||
match.var(x = z.A) |
||||
} |
||||
``` |
||||
=> |
||||
``` |
||||
Block (TypePattern) { |
||||
stloc z(isinst T(expr)) |
||||
final: (z != null) |
||||
&& Block(VarPattern) { |
||||
stloc x(z.A) |
||||
final: ldc.i4 1 |
||||
} |
||||
} |
||||
``` |
||||
4) `expr is C { A: var x, B: 42, C: { A: 4 } } z` |
||||
=> |
||||
``` |
||||
match.type C(z = expr) { |
||||
match.var (x = z.A), |
||||
comp (z.B == 42), |
||||
match.recursive (temp2 = z.C) { |
||||
comp (temp2.A == 4) |
||||
} |
||||
} |
||||
``` |
||||
=> |
||||
``` |
||||
Block (TypePattern) { |
||||
stloc z(isinst C(expr)) |
||||
final: (z != null) |
||||
&& Block(VarPattern) { |
||||
stloc x(z.A) |
||||
final: ldc.i4 1 |
||||
} |
||||
&& comp (z.B == 42) |
||||
&& Block(RecursivePattern) { |
||||
stloc temp2(z.C) |
||||
final: (temp2 != null) |
||||
&& comp (temp2.A == 4) |
||||
} |
||||
} |
||||
``` |
||||
5) `expr is C(var x, var y, <4) { ... }` |
||||
=> |
||||
``` |
||||
match.recursive.type.deconstruct(C tmp1 = expr) { |
||||
match.var(x = deconstruct.result0(tmp1)), |
||||
match.var(y = deconstruct.result1(tmp1)), |
||||
comp(deconstruct.result2(tmp1) < 4), |
||||
} |
||||
``` |
||||
|
||||
6) `expr is C(1, D(2, 3))` |
||||
=> |
||||
``` |
||||
match.type.deconstruct(C c = expr) { |
||||
comp(deconstruct.result0(c) == 1), |
||||
match.type.deconstruct(D d = deconstruct.result1(c)) { |
||||
comp(deconstruct.result0(d) == 2), |
||||
comp(deconstruct.result1(d) == 2), |
||||
} |
||||
} |
||||
``` |
||||
|
||||
7) `x is >= 0 and var y and <= 100` |
||||
``` |
||||
match.and(tmp1 = x) { |
||||
comp(tmp1 >= 0), |
||||
match.var(y = tmp1), |
||||
comp(tmp1 <= 100) |
||||
} |
||||
``` |
||||
|
||||
8) `x is not C _` |
||||
=> |
||||
``` |
||||
logic.not( |
||||
match.type(C tmp1 = x) {} |
||||
) |
||||
``` |
||||
|
||||
9) `expr is (var a, var b)` (when expr is object) |
||||
=> |
||||
``` |
||||
match.type.deconstruct(ITuple tmp = expr) { |
||||
match.var(a = deconstruct.result0(tmp)), |
||||
match.var(b = deconstruct.result1(tmp)), |
||||
} |
||||
``` |
||||
|
||||
10) `expr is (var a, var b)` (when expr is ValueTuple<int, int>) |
||||
=> |
||||
``` |
||||
match.recursive(tmp = expr) { |
||||
match.var(a = tmp.Item1), |
||||
match.var(b = tmp.Item2), |
||||
} |
||||
``` |
