package parseff

0.1.0

Initial release of Parseff -- a direct-style parser combinator library for OCaml 5 powered by algebraic effects.

• Direct-style parsers as plain unit -> 'a functions, no monadic or binding operators needed
• Algebraic effects for control flow, backtracking, and streaming input
• Typed errors via polymorphic variants with position tracking
• Built-in error variants: `Expected, `Unexpected_end_of_input, `Depth_limit_exceeded
• Automatic backtracking with or_, one_of, and one_of_labeled
• Primitive parsers: consume, satisfy, char, match_regex, take_while, skip_while, fail, error
• Repetition combinators: many, sep_by, between, end_by, count, optional
• Operator chains: chainl, chainl1, chainr, chainr1 for expression parsing
• Look-ahead parsing and depth-limited recursion via rec_ (default depth: 128)
• Convenience parsers: digit, letter, alphanum, whitespace, any_char
• Zero-copy span APIs: take_while_span, sep_by_take_span returning { buf; off; len } records
• Fused operations for hot paths: sep_by_take, fused_sep_take, skip_while_then_char
• Streaming support via Source.of_string, Source.of_channel, Source.of_function
• Backtrack-across-chunk-boundary support for streaming sources
• Non-fatal diagnostics with warn / warn_at, rolled back on backtracking
• parse_until_end / parse_source_until_end runners that collect diagnostics
• Error labeling with expect and one_of_labeled for clear error messages
• Domain-safe: no global mutable state, independent parses run in parallel across OCaml 5 domains
• 2-4x faster than Angstrom and MParser on equivalent parsers
• Single runtime dependency: re for regex support
