Parsing configuration for SPDX expression

Fields

allow_lower_case_operators: bool

The AND, OR, and WITH operators are required to be uppercase in the SPDX spec, but enabling this option allows them to be lowercased

allow_slash_as_or_operator: bool

Allows the use of / as a synonym for the OR operator.

This also allows for not having whitespace between the / and the terms on either side

allow_imprecise_license_names: bool

Allows some invalid/imprecise identifiers as synonyms for an actual license identifier.

See IMPRECISE_NAMES for a list of the current synonyms. Note that this list is not comprehensive but can be expanded upon when invalid identifiers are found in the wild.

allow_postfix_plus_on_gpl: bool

The various GPL licenses diverge from every other license in the SPDX license list by having an -or-later variant that is used as a suffix on a base license (eg. GPL-3.0-or-later) rather than the canonical GPL-3.0+.

This option just allows GPL licenses to be treated similarly to all of the other SPDX licenses.

Implementations

impl ParseMode

pub const STRICT: Self = _

Strict, specification compliant SPDX parsing.

1. Only license identifiers in the SPDX license list, or Document/LicenseRef, are allowed. The license identifiers are also case-sensitive.
2. WITH, AND, and OR are the only valid operators

pub const LAX: Self = _

Allow non-conforming syntax for crates-io compatibility

1. Additional, invalid, identifiers are accepted and mapped to a correct SPDX license identifier. See IMPRECISE_NAMES for the list of additionally accepted identifiers and the license they correspond to.
2. / can by used as a synonym for OR, and doesn’t need to be separated by whitespace from the terms it combines
