@appdmg/tn1150

HFS Plus TN1150 string comparison and normalization helpers for appdmg packages.

This package stays as a small compatibility boundary because compare() carries the TN1150 case-insensitive ordering table used by .DS_Store behavior. The old runtime dependency on unorm was removed; normalize() now uses Node.js String.prototype.normalize('NFD').

Installation

npm install @appdmg/tn1150

Usage

const tn1150 = require('@appdmg/tn1150')

filenames.sort(tn1150.compare)

const normalized = tn1150.normalize(filename)

API

tn1150.compare(lhs, rhs)

Compares two strings using the case-insensitive ordering table from Apple's TN1150 FastUnicodeCompare routine.

tn1150.normalize(text)

Returns text.normalize('NFD'), which matches the previous unorm.nfd behavior for the compatibility cases covered by this package's tests.

Migration Notes

The package name changed from tn1150 to @appdmg/tn1150.

The supported runtime changed to Node.js 24 and newer.

The runtime dependency on unorm was removed. Normalization now uses the Node.js built-in Unicode canonical decomposition support.
