normalization_profile_info: Canonical-host normalization profile identity

In punycoder: Unicode and Punycode Domain Name Processing

Canonical-host normalization profile identity

Description

Returns the stable, machine-readable identity of a normalization profile. Called with no arguments it reports the default (fully strict) profile host_normalize() applies; the check_hyphens, use_std3, and verify_dns_length arguments report the identity of a specific flag set so a caller can describe the exact profile a given normalization used. Downstream packages key reproducibility on the full per-parameter column set; profile is a coarse cache token (distinct per flag set, but no longer load-bearing alone) and the backend column is diagnostic only and must never enter a reproducibility or cache key.

Usage

normalization_profile_info(
  check_hyphens = TRUE,
  use_std3 = TRUE,
  verify_dns_length = TRUE
)

Arguments

check_hyphens, use_std3, verify_dns_length

Logical scalars selecting the flag set to report. Each defaults to TRUE (the strict profile).

Details

check_bidi, check_joiners, and transitional are fixed by the profile (UTS #46 non-transitional, both bidi and joiner checks always on) and are reported as constant columns rather than arguments.

Value

A one-row data.frame with columns profile, unicode_version, idna, transitional, use_std3, check_hyphens, check_bidi, check_joiners, verify_dns_length, and backend.
