blaseball-game-finder

This repo contains a command line tool called game-finder that helps find game IDs of blaseball games. This is a utility function to make other tools easier to use.

You can use command line flags or configuration options to filter on conditions, including:

• Season
• Day
• Team (home, away, either)
• Opponent
• Postseason

Output Formats

The game-finder utility can output data in text format or JSON format.

Specifying the text output format is as easy as adding the --text flag, and outputs one game ID per line, nothing else:

Specifying JSON output format can be done with the --json flag, and outputs a JSON object with information about the teams, odds, score, season, and day for each game that matches the criteria specified with the command line flags.

Installation

pip

pip install git+https://github.com/ch4zm/blaseball-core-game-data.git#egg=blaseball_core_game_data
pip install git+https://github.com/ch4zm/blaseball-game-finder.git#egg=blaseball_game_finder

source

Start by cloning the package:

git clone https://github.com/ch4zm/blaseball-game-finder
cd blaseball-game-finder

If installing from source, it is recommended you install the package into a virtual environment. For example:

virtualenv vp
source vp/bin/activate

Now build and install the package:

python setup.py build
python setup.py install

Now test that the tool is available on the command line, and try out a command to search for some games:

which game-finder
game-finder --season 4 --game 20 --team Sunbeams

Quick Start

The way this tool works is, it creates a JSON data object, applies some filters to it based on command line flags provided by the user, then dumps the game IDs in the specified format. All command line flags can also be specified in a config file.

Command line flags

Command line flags are grouped into data options and format options.

Data options:

• Season: Set season for game data using --season. For multiple seasons, repeat the flag: --season 1 --season 2

• (Optional) Our Team: Specify only one of the following:

  • Team: use the --team flag to specify the short name of your team (use --help to see valid choices). For multiple teams, use multiple --team flags.
  • Division: use the --division flag to specify the name of a division. Surround division name in quotes, e.g., --division "Lawful Evil"
  • League: use the --league flag to specify the Good/Evil league

• (Optional) Versus Team: Specify only one of the following:

  • Versus Team: use the --versus-team flag to specify the short name of the opposing team (use --help to see valid choices). For multiple teams, use multiple --versus-team flags.
  • Versus Division: use the --versus-division flag to specify the name of the versus division. Surround division name in quotes, e.g., --versus-division "Lawful Evil"
  • Versus League: use the --versus-league flag to specify the versus Good/Evil league

(If neither flag is specified, it will include all games between all teams.)

Format options:

• JSON: Use --json to specify that the output should be in JSON format. This will include details about each game (see above).

• Text: (Default choice) Use --text to output game IDs as plain text, one game ID per line, with no additional information.

Using a configuration file:

• Config file: use the -c or --config file to point to a configuration file (see next section).

Configuration file

(Note: several configuration file examples are provided in a section below.)

Every command line flag can be specified in a configuration file as well. To reproduce the following command line call,

game-finder --season 1 --season 2 --team Tigers --versus-team Pies --text

we could create a configuration file named config.ini with the contents:

season = [1, 2]
team = Tigers
versus-team = Pies
text

and run blaseball-game-finder specifying that configuration file:

game-finder --config config.ini
# or
game-finder -c config.ini

This would produce identical output to the command with all the flags.

You can also use both a config file and command line flags; the command line flags will take precedence over config file options if a parameter is specified by both.

Data

The data set used by this tool comes from blaseball.com's /games API endpoint. The data set is imported from blaseball-core-game-data.

Configuration Examples

See config.example.ini in the repo for an example config file.

Show game IDs from season 3 and season 4 for all games involving the Hades Tigers:

[data]
season = [3, 4]
team = Tigers

[format]
text

Include games involving the Pies too:

[data]
season = [3, 4]
team = [Tigers, Pies]

[format]
text

Include games only involving both the Tigers and the Pies:

[data]
season = [3, 4]
team = Tigers
versus-team = Pies

[format]
text

Show game IDs from season 1 for all teams in the Good League:

[data]
season = 1
league = Good

[format]
text

Show game IDs for all postseason games:

[data]
postseason

[format]
text

Show the same game IDs but in JSON format:

[data]
postseason

[format]
json

Python API

If you prefer to call this tool from Python directly, rather than from the command line, you can import and call the game_finder function and pass it a list of strings containing the flags you would normally pass on the command line.

from game_finder.command import game_finder

flags = "--season 1 --season 2 --team Tigers --versus-team Pies"
output = game_finder(flags.split(" "))
game_ids = [j.strip() for j in output.split("\n")]
print(game_ids)

If you prefer to store the JSON game object returned by game-finder as a native Python dictionary, you can use json.loads():

from game_finder.command import game_finder
import json

flags = "--json --season 1 --season 2 --team Tigers --versus-team Pies"
output = game_finder(flags.split(" "))
json_data = json.loads(output)
print(json_data)

Software architecture

This software consists of two parts:

• The command line flag and config file parser (uses configargparse library) - see cli/command.py
• The BaseFormat object that provides a formatting layer to print out the JSON data in either plain text format (one game ID per line) or in JSON format (reduced set of information from the original JSON). All filtering is performed using list comprehensions, so that a data soting tool like pandas is not needed.

Who is this tool for?

This tool is for the blaseball community. It will be useful to people interested in exploring game data, people who are brainstorming about lore for their team, and people who are looking for a starting point for developing their own blaseball tool.

Future work

• Add weather

Libraries used

This command line tool uses the following libraries under the hood:

• blaseball-core-game-data
• configarparse for handling CLI arguments
