# Prompter

a simple tool to help format LLM prompts dynamically

## usage

```javascript

const Prompter = require("@ryanforever/prompter")

const prompter = new Prompter({

	fromFiles: {

		systemPrompt: "./prompts/system-prompt-v1.js"

	},

	fromText: {

		prompt2: "you are a helpful assistant named {{assitantName}}.  the current date is {{currentDate}}" // format variables in {{}}

	},

	strict: false // throw error if input variables do not match prompt variables, or variables are missing

})

// assign variables at run time

let prompt = prompter.get("prompt2", {

	assitantName: "botlab",

	currentDate: new Date(Date.now())

})

// upsert prompt variables.  this will only change the {{currentDate}} variable, leaving all other variables the same

prompt = prompter.update("prompt2", {

	currentDate: new Date(Date.now())

})

```

## tools

```javascript

const prompter = require("@ryanforever/prompter")

// in line text prompt

let prompt1 = prompter.fromText("hello {{username}}", {

	username: "ryan forever"

})

// read prompt text from a file instead

let prompt2 = prompter.fromFile("./my-prompt.txt", {

	currentDate: new Date(Date.now())

})

```
