Tasks

1. Read files from the user's local system

Read the files provided by the user, which contain short lyrical forms such as poems, haikus, or limericks. The path is ./.shepts/shepts.json

language SupportedLanguagesEnum = 'PL' | 'EN' text String

2. Read current MessageTranslation model

Check path prisma/schema.prisma for the current structure of the MessageTranslation model to understand what fields are required for creating new entries.

3. Create database rows based on the content

Use the following function to calculate length, encoding and number of parts for each lyrical form before creating a new MessageTranslation entry in the database.

// Calculate SMS encoding, length accounting, and segment count.
function smsMetrics(text: string) {
  // GSM-7 basic and extension tables
  const GSM7_BASIC =
    "@£$¥èéùìòÇ\nØø\rÅåΔ_ΦΓΛΩΠΨΣΘΞÆæßÉ !\"#¤%&'()*+,-./0123456789:;<=>?" +
    "¡ABCDEFGHIJKLMNOPQRSTUVWXYZÄÖÑÜ`¿abcdefghijklmnopqrstuvwxyzäöñüà";
  const GSM7_EXT = "^{}\\[~]|€";

  let gsmCount = 0;
  for (const ch of text) {
    if (GSM7_BASIC.includes(ch)) {
      gsmCount += 1;
    } else if (GSM7_EXT.includes(ch)) {
      gsmCount += 2; // escape-prefixed
    } else {
      // Non-GSM char → UCS-2 for whole message
      const len = [...text].length; // safe for surrogate pairs
      const perPart = 67;
      const parts = len <= 70 ? 1 : Math.ceil(len / perPart);
      return {
        encoding: "UCS-2" as const,
        length: len,
        maxSingle: 70,
        perPart,
        parts,
      };
    }
  }

  // If we got here, text fits GSM-7
  const perPart = 153;
  const parts = gsmCount <= 160 ? 1 : Math.ceil(gsmCount / perPart);
  return {
    encoding: "GSM-7" as const,
    length: gsmCount, // counts escapes correctly
    maxSingle: 160,
    perPart,
    parts,
  };
}

4. Create a .json file ready for upload

Generate a .json file containing all the new MessageTranslation entries created from the lyrical forms, formatted according to the database schema. Put it in the path: ./.shepts/shepts_upload.json
