Crate patch_prolog_frontend 

plg-frontend: ISO Prolog tokenizer, parser, and source-level static analysis, ported from patch-prolog.

Consumed by the compiler and the LSP. Compiled Prolog binaries carry a minimal goal-only parser inside the runtime instead.

Modules

error

ISO Prolog error terms.

lint

Static lint: calls to predicates that are defined nowhere.

parse_error

Structured parse error: a message plus the source Span it points at.

parser

Operator-precedence parser for ISO Prolog programs and queries.

source_map

Maps byte offsets (the stable position in a Span) back to human line/column. Built on demand from the source text a consumer already holds — positions are not threaded through parser return types.

tokenizer

Tokenizer for ISO Prolog source.
