Module pattern 

Parser module for formatparse-core Parse format patterns into regex strings and field specifications (pure Rust).

Constants

MAX_NESTED_FORMAT_DEPTH

Maximum recursive depth when compiling nested format patterns (GitHub issue #12).

Functions

field_types_match

Check if two field types match (for repeated name validation)

normalize_field_name

Normalize field name for use inside (?P<name>...) capture groups.

parse_field

Parse a single field specification from the pattern

parse_field_path

Parse a field name into a path (for dict-style names like “hello[world]” -> [“hello”, “world”])

parse_format_spec

Parse format specifier string into FieldSpec

parse_pattern

Parse a format pattern string into regex parts, field specs, and names allow_empty_delimited_default_string: when false, default string fields always use .+? (used for the unanchored search regex so search/findall do not stop early).

validate_multiline_mvp

Reject :ml / :blk combined with numeric-only format specifiers (GitHub issues #8, #69, #70).

Type Aliases

ParsedPatternParts

Result tuple from parse_pattern: compiled pattern string, search regex string, field specs, original and normalized field names, normalized-to-original name map, and whether "" may match when every field is a default unconstrained string.
