globfilter

Portable directory walking with includes and excludes.

Motivating example: You want to allow the user to select paths within a project.

include = ["src", "License.txt", "resources/icons/*.svg"]
exclude = ["target", "/dist", ".cache", "*.tmp"]

When traversing the directory, you can use GlobDirFilter::from_globs(...)?.match_directory(&relative) skip directories that never match in WalkDirs filter_entry.

Syntax

This crate supports the cross-language, restricted glob syntax from PEP 639:

• Alphanumeric characters, underscores (_), hyphens (-) and dots (.) are matched verbatim.
• The special glob characters are:
  • *: Matches any number of characters except path separators
  • ?: Matches a single character except the path separator
  • **: Matches any number of characters including path separators
  • [], containing only the verbatim matched characters: Matches a single of the characters contained. Within [...], the hyphen indicates a locale-agnostic range (e.g., a-z, order based on Unicode code points). Hyphens at the start or end are matched literally.
• The path separator is the forward slash character (/). Patterns are relative to the given directory, a leading slash character for absolute paths is not supported.
• Parent directory indicators (..) are not allowed.

These rules mean that matching the backslash (\) is forbidden, which avoid collisions with the windows path separator.
