@gram-lang/i18n

Shared unit/time normalization and UI-string dictionaries, used internally across the pipeline (the parser doesn't normalize units — that happens in @gram-lang/kitchen's scaling engine and @gram-lang/analyzer's mass standardization) so "càs", "tbsp", and "cuillère à soupe" are all recognized as the same unit regardless of which locale a recipe or a database entry was written in.

Canonical units & aliases

normalizeUnit maps any recognized alias (English or French, case-insensitive) to its canonical short form:

Canonical	Aliases
tsp	teaspoon, teaspoons
tbsp	tablespoon, tablespoons
tad	tads
dash	dashes
pinch	pinches
smidgen	smidgen, smidge, smidgens
drop	drops
cup	cups
pt	pint, pints
qt
gal	gallon, gallons
fl oz	floz, fl. oz., fluid ounce, fluid ounces
ml	milliliter, milliliters
cl	centiliter, centiliters
dl	deciliter, deciliters
l	liter, liters
mg	milligram, milligrams
g	gram, grams
kg	kilo, kilos, kilogram, kilograms
oz	ounce, ounces
lb	lbs, pound, pounds

function normalizeUnit(rawUnit: string | undefined | null, lang?: string): string

import { normalizeUnit } from '@gram-lang/i18n';

normalizeUnit('càs');              // "tbsp"
normalizeUnit('Tablespoons');      // "tbsp"
normalizeUnit('kilo', 'fr');       // "kg" (language-scoped lookup, falls back to global)

Unrecognized input is returned lowercased and trimmed, unchanged.

Time units

Same alias-normalization pattern, scoped to durations:

Canonical	Aliases
d	day, days
h	hour, hours
m	min, mins, minute, minutes
s	sec, secs, second, seconds

function resolveTimeUnit(unit?: string | null, lang?: string): string

import { resolveTimeUnit } from '@gram-lang/i18n';

resolveTimeUnit('minutes'); // "m"
resolveTimeUnit('heures', 'fr'); // "h"

Default ingredient categories

Used by gram shop and other consumers to group a shopping list by culinary family when an ingredient's database entry has no explicit category:

Default categories
Vegetables
Fruits
Meat
Seafood
Dairy
Grains
Legumes
Nuts
Oils
Herbs
Spices
Condiments
Sugars
Beverages
Other

CATEGORY_KEYS exports stable, locale-invariant category keys (produce, dairy, meat, pantry, ...), and getCategoryLabels(lang) resolves those keys to human-readable localized labels:

function getDefaultCategories(lang?: string): string[] // defaults to 'en'
function getCategoryLabels(lang?: string): Record<CategoryKey, string>

import { getDefaultCategories, getCategoryLabels, CATEGORY_KEYS } from '@gram-lang/i18n';

getDefaultCategories('fr'); // ["Légumes", "Fruits", "Viandes", ...]
getCategoryLabels('fr').produce; // "Légumes"

Unit conversion tables

@gram-lang/i18n acts as the single source of truth for same-family unit conversion factors (UNIT_CONVERSIONS) and time-to-minute duration multipliers (TIME_TO_MINUTES):

import { UNIT_CONVERSIONS, TIME_TO_MINUTES } from '@gram-lang/i18n';

UNIT_CONVERSIONS.mass.map.kg; // 1000 (grams)
UNIT_CONVERSIONS.volume.map.tbsp; // 14.7868 (mL)
TIME_TO_MINUTES.h; // 60 (minutes)
