# Explanation model
|
|
|
|
The community provider converts regexpp nodes into a stable application AST
|
|
inside the syntax worker. Nodes carry deterministic IDs, UTF-16 ranges, raw
|
|
source, capture metadata, quantifier bounds, assertion kind, support status,
|
|
provider identity and provenance.
|
|
|
|
Explanations are original deterministic text selected by node type. Nullable
|
|
and minimum/maximum consumed-length properties are derived recursively where
|
|
the normalized node semantics support them. Backreference lengths and exact
|
|
bounds for Unicode properties of strings remain unknown rather than being
|
|
guessed.
|
|
|
|
regexpp 4.12.2 does not expose tolerant recovery. A malformed pattern therefore
|
|
gets the provider's exact diagnostic plus an application-owned error node. No
|
|
partial regexpp AST is claimed.
|
|
|
|
The explanation tree is structural. It is never called an actual execution
|
|
trace. Selecting a node selects and scrolls its exact editor range; selecting
|
|
pattern text chooses the smallest enclosing node.
