Installation

# install from pypi
pip install vimgolf-gym

# or install the latest version from github
pip install git+https://github.com/james4ever0/vimgolf-gym.git

If you do not have Vim installed locally, or want an extra layer of isolation, you can use this docker image:

# build the image
bash build_docker_image.sh
docker tag cybergod_vimgolf_gym agile4im/cybergod_vimgolf_gym

# or pull the image
docker pull agile4im/cybergod_vimgolf_gym

Usage

Basic interactions:

import vimgolf_gym
import vimgolf_gym.dataclasses

# a basic "hello world" challenge
env_name = "vimgolf-test"

# a local challenge, format is "vimgolf-local-<challenge_id>"
env_name = "vimgolf-local-4d1a1c36567bac34a9000002"

# an online challenge, format is "vimgolf-online-<challenge_id>"
env_name = "vimgolf-online-4d1a1c36567bac34a9000002"

# if you have vim installed locally
env = vimgolf_gym.make(env_name)

# or run the executor with docker
env = vimgolf_gym.make(env_name, use_docker=True)

# if you want to customize the challenge
env = vimgolf_gym.make("vimgolf-custom", custom_challenge = vimgolf_gym.dataclasses.VimGolfCustomChallenge(input="", output="hello world\n"))

# if you want to read the buffer of the editor (and avoid cheating)
env = vimgolf_gym.make(env_name, log_buffer=True)

# retrieve the editor buffer to track progress
buffer = env.buffer

# take an action
env.act("hello world\n")

# take a screenshot and output a PIL image
img = env.screenshot()

# preview screenshot
env.render()

# reset the environment
env.reset()

# check if the environment has at least one success result
if env.success:
   # VimGolfEnvResult: (correct: bool, keys: str, score: int)
   result: vimgolf_gym.dataclasses.VimGolfEnvResult = env.get_last_success_result()

The local challenges are stored in ~/.cache/cybergod-vimgolf-challenges/.

If you want to learn more about the local challenges, use the following code:

import vimgolf_gym
import vimgolf_gym.dataclasses

challenge_id = "4d1a1c36567bac34a9000002"

# list all local challenge ids
local_challenge_ids: list[str] = vimgolf_gym.list_local_challenge_ids()

# get the challenge definition
# VimGolfChallengeDefinition: (input: InputOutputModel, output: InputOutputModel, client_version: str)
# InputOutputModel: (data: str, type: str)
challenge: vimgolf_gym.dataclasses.VimGolfChallengeDefinition = get_local_challenge_definition(challenge_id)

# get the challenge metadata
# VimGolfChallengeMetadata: (href: str, title: str, detail: str, challenge_hash: str)
metadata: vimgolf_gym.dataclasses.VimGolfChallengeMetadata = vimgolf_gym.get_local_challenge_metadata(challenge_id)

# get the worst solution
# VimGolfPublicSolution: (rank: str, solution: str, header: str)
solution: vimgolf_gym.dataclasses.VimGolfPublicSolution = vimgolf_gym.get_local_challenge_worst_solution(challenge_id)

# get the worst solution header
# VimGolfParsedPublicSolutionHeader: (rank: str, score: str, user_name: str, user_id: str, data: datetime)
header: vimgolf_gym.dataclasses.VimGolfParsedPublicSolutionHeader = vimgolf_gym.get_local_challenge_worst_solution_header(challenge_id)

If you want to obtain online challenge ids, you have a few options:

1. Visit the Vimgolf website and look for the challenge ids.
2. Use vimgolf command
   • Install: pip3 install vimgolf
   • Run: vimgolf list
