lamp v1.0.2

LaMP

Language Model Prompter.

Query GPT models from the safety of your terminal. Unix-friendly for use within bash pipelines. Supports continuous conversation, like the OpenAI interface, but with the benefit of being able to switch model at will.

lamp/1.0.0

Usage:
  $ lamp [...flags]

Input will be taken from stdin by default, unless the '-p' or '-e' flags
are given. The model's response will be written to stdout.

Options:
  -m, --model <model>    Which GPT model to use (default: gpt-3.5-turbo)
  -p, --prompt <prompt>  Pass a prompt to the GPT model
  -e, --edit             Edit a prompt for the GPT model
  -c, --continue         Continue from the last message
  -v, --version          Display version number
  -h, --help             Display this message

Installation

npm install -g lamp

Configuration

export OPENAI_API_KEY=your_api_key_here

or

echo "your_api_key_here" > ~/.lamp-data/creds.txt

Usage

The model's response will always be printed to stdout, with no embellishment, making lamp suitable for unix-style piping. Prompts are read from stdin by default:

$ echo "Write me a poem about crows." > prompt.txt
$ cat prompt.txt | lamp
Crows in the sky,
Dark as the night.
Silent they fly,
In endless flight.

Prompts can be given directly as an argument with the -p/--prompt flag, and you can bring up your configured EDITOR to write a prompt with the -e/--edit flag. To change the model from the default of gpt-3.5-turbo, you can use the -m/--model flag:

$ lamp -m gpt-4 -p "Write me a poem about crows."
In twilight skies, the crows emerge,
Their shadows dance, as darkness surge,
They caw and gather, velvet wing,
A murder's wary offering.

To continue a conversation, simply call lamp again with the -c/--continue flag enabled. This has the same behaviour as a once-off call, but the current conversation will be passed to GPT along with the prompt for context.

$ lamp -m gpt-4 -p "Write me a javascript function that lists all of the primes between 1 and n."
function listPrimes(n) {
  const primes = [];
  for (let i = 2; i <= n; i++) {
    let isPrime = true;
    for (let j = 2; j * j <= i; j++) {
      if (i % j === 0) {
        isPrime = false;
        break;
      }
    }
    if (isPrime) {
      primes.push(i);
    }
  }
  return primes;
}

$ lamp -c -p "Now modify it to return the primes in reverse order."
function listReversedPrimes(n) {
  const primes = [];
  for (let i = 2; i <= n; i++) {
    let isPrime = true;
    for (let j = 2; j * j <= i; j++) {
      if (i % j === 0) {
        isPrime = false;
        break;
      }
    }
    if (isPrime) {
      primes.push(i);
    }
  }
  return primes.reverse();
}

Note that in this last example, the first response was generated using gpt-4, but the second response was generated with the default gpt-3.5-turbo model. You can switch models mid-conversation whenever you like.
