Add TypeChat service

[abichinger]

Servus!

Thanks for this awesome tool!

I added a new services which uses OpenAI and TypeChat to translate all strings.

New services:

• typechat - translates a batch of 10 with a single prompt
• typechat-manual - feed the prompt into a LLM and copy the result

Environment variables:	Name	Default
OPENAI_API_KEY	required
OPENAI_MODEL	text-davinci-003
OPENAI_ENDPOINT	https://api.openai.com/v1/chat/completions
OPEN_AI_BATCH_SIZE	10
TYPECHAT_SCHEMA_NAME	AppLocalizations
TYPECHAT_SCHEMA_COMMENT	undefined

I wasn't able to test it with the official OpenAI API, because I don't have an OpenAI API key. But it worked with a local llama-cpp-python web server.

Example

A generated prompt will look like this:

You are a service that translates user requests into JSON objects of type "AppLocalizations" according to the following TypeScript definitions:
\`\`\`
export interface AppLocalizations {
  globalRankings: string;
  share: string;
  shareText: string;
  rank: string;
  train: string;
  forfeit: string;
  forfeitContent: string;
  yes: string;
  no: string;
}
\`\`\`
The following is a user request:
"""
Translate the following JSON object from English into German:
{
  "globalRankings": "Global Rankings",
  "share": "Share",
  "shareText": "Yo! Check out Nono Battle.",
  "rank": "Rank",
  "train": "Practice",
  "forfeit": "Forfeit",
  "forfeitContent": "Are you sure you want to forfeit?",
  "yes": "Yes",
  "no": "No"
}
"""
The following is the user request translated into a JSON object with 2 spaces of indentation and no properties with the value undefined:

Response from ChatGPT:

Of course, here's the translated JSON object in German according to the provided TypeScript definitions:

\`\`\`json
{
  "globalRankings": "Weltweite Rangliste",
  "share": "Teilen",
  "shareText": "Hey! Schau dir Nono Battle an.",
  "rank": "Rang",
  "train": "Üben",
  "forfeit": "Aufgeben",
  "forfeitContent": "Bist du sicher, dass du aufgeben möchtest?",
  "yes": "Ja",
  "no": "Nein"
}
\`\`\`

The JSON object is formatted with 2 spaces of indentation, and properties with the value undefined have been omitted. If you need any further assistance or modifications, feel free to let me know!

Thank you for submitting the PR! The typechat-approach looks interesting and could be an alternative to the current openai-service with a primitive prompt-engineering.

However, there is currently the problem that the typechat-tests are failing in the CI: https://github.com/fkirc/attranslate/actions/runs/5770043007/job/15643564890?pr=256

Based on the test-summary, it seems that some module-import within the typechat-package is failing?

Looks like typechat requires node >= 18. (package.json)

I added a check to ensure the correct node version is installed.

After upgrading node to v18, I see a new CI-error:

src/util/util.ts:10:20 - error TS7016: Could not find a declaration file for module 'semver'. '/home/runner/work/attranslate/attranslate/node_modules/semver/index.js' implicitly has an 'any' type. Try npm i --save-dev @types/semver if it exists or add a new declaration (.d.ts) file containing declare module 'semver';

10 import semver from "semver";

Found 1 error.

Oops, I forgot to commit the package.json file

Now the CI passes again, I merged typechat and released version 2.1.0!
