Module pattern 

Substring → glob → regex pattern promotion, shared by every tool option that accepts a pattern.

The rule lets a caller write the simplest thing that expresses intent and have the tool infer how literally it was meant:

• a string with no metacharacters is a Literal substring (regex-escaped, matched verbatim);
• a string with only glob metacharacters (*, ?, [ … ]) that is not a valid regex is a Glob, converted to an equivalent regex;
• anything else carrying regex metacharacters and forming a valid expression is a Regex, used exactly as written.

Enums

PatternKind

How a raw pattern string was interpreted by classify.

Functions

classify

Classify a raw pattern according to the suite’s promotion rule.

compile

Compile a pattern for content / unanchored matching (e.g. ct-search --grep or any ct-test matcher): the result matches anywhere in the haystack.

compile_anchored

Compile a pattern for whole-name matching: anchored to the full string, so *.java means “the name ends in .java”, not merely “contains”.

compile_name_set

Compile a '|'-separated set of whole-name alternatives, each promoted and anchored. An entry name matches the set when it matches any alternative, mirroring find’s -name a -o -name b.

glob_to_regex

Convert a glob pattern into an (unanchored) regular-expression source.

promote

Produce the regex source a raw pattern promotes to, without anchoring.
