gamedayapi - an mlb gameday api for go

gamedayapi is an API for interacting with MLB Gameday files using the go programming language.

Included is a simple command-line utility for fetching and saving Gameday files to your local filesystem.

Prerequisites: go

To build and run from the command line

In your go workspace, under a directory github.com/ecopony/

git clone [email protected]:ecopony/gamedayapi.git
cd gamedayapi
go build gameday/mlbgd.go

To fetch files for a single game:

./mlbgd game sea 2014-07-22

To fetch files for a full season for a team:

./mlbgd games-for-team-and-year sea 2014 

To fetch files for multiple seasons for a team:

./mlbgd games-for-team-and-years sea 2012 2013 2014

To fetch all games for all teams for a given year:

./mlbgd games-for-year 2014

To see a list of valid team codes for a given year:

./mlbgd valid-teams-for-year 2014

Using the API from your own go code

Import the API.

import "github.com/ecopony/gamedayapi"

To work with a game:

date, _ := time.Parse("2006-01-02", "2014-06-02")
game, _ := gamedayapi.GameFor("sea", date)
fmt.Println(game.Venue)
fmt.Println(game.HomeTeamName)
...

To operate on all games in a season:

gamedayapi.FetchByTeamAndYears("sea", []int{2012, 2013, 2014}, exampleOfNavigatingAllPitches)

func exampleOfNavigatingAllPitches(game *gamedayapi.Game) {
     log.Println(">>>> " + game.ID + " <<<<")
     for _, inning := range game.AllInnings().Innings {
          for _, atBat := range inning.AtBats() {
               for _, pitch := range atBat.Pitches {
                    log.Println("> " + pitch.Des)
               }
          }
     }
}

The function passed into FetchByTeamAndYears will be passed each game. This could be used to do analysis to save data to an alternate format or something else fun and entertaining and within the limitations of the usage restrictions.

Adding schedule files

The schedule files come from Retrosheet. Updated schedule files can be found here:

https://www.retrosheet.org/schedule/

Add them as needed to your local repo. Feel free to submit a PR for new files.
