mispar

Hebrew gematria with all the classical counting methods — not just the standard count. מספר, "number." Zero dependencies.

npm install mispar

Why

Every gematria package on npm does one thing: the standard count (and the venerable gematriya converts numerals ↔ Hebrew letters, which is a different job entirely). But the tradition has many counting methods — final letters as 500–900, ordinal values, digit reduction, squares, spelled-out letter names, the atbash and albam ciphers — and they're exactly what gematria tooling needs.

import { gematria, letterValues, atbash } from "mispar";

gematria("חי");                    // 18
gematria("שלום");                  // 376
gematria("שָׁלוֹם");                 // 376 — niqqud stripped automatically

gematria("אלהים");                 // 86
gematria("אלהים", "gadol");        // 646 — final ם counts as 600
gematria("אמת", "katan");          // 9   — per-letter digit reduction
gematria("אמת", "katan-mispari");  // 9   — digital root of 441
gematria("א", "milui");            // 111 — אלף, the letter spelled out

atbash("בראשית");                  // the cipher as a string transform
letterValues("שלום");              // [{letter:"ש",value:300}, …] — build a calculator

The 13 methods

| Method | What it counts | | --- | --- | | hechrachi (default) | standard absolute values, א=1 … ת=400 | | gadol | finals ך ם ן ף ץ count 500–900 | | katan | each letter reduced to one digit (י=1, ק=1) | | siduri | ordinal position, א=1 … ת=22 | | katan-mispari | digital root of the standard total | | perati | each letter's value squared | | meshulash | each letter's value cubed | | kidmi | cumulative: each letter = sum of all values up to it (י=55) | | boneeh | building: the running total re-added at every letter | | haakhor | positional: value × position in the word | | milui | each letter's spelled-out name (א→אלף=111); spellings overridable | | atbash | standard value after the א↔ת cipher | | albam | standard value after the א↔ל cipher |

Also exported: atbash(text) / albam(text) as string transforms, letterValues(text, method?) for per-letter breakdowns, METHODS, and MILUI_SPELLINGS (the default naming tradition — variants like הי/ואו/פא/תיו can be passed via options.spellings).

Niqqud and cantillation are stripped automatically; maqaf (־) separates words; non-Hebrew characters are ignored unless { strict: true }.
