Polylinguist

More exact language usage stats from Github profile.

Features:

• No limits like only "top 10 languages"
• Both public & private repos via access token
• Aliasing similar languages to same stats. For example, combine C & C++ to C/C++
• Ignoring languages. For example, drop markup like SCSS, HTML, Twig etc.
• Ignoring repositories. For example, drop a repository that contains megabytes of generated code, skewing statistics.

Install

go get github.com/stscoundrel/polylinguist

Usage

Polylinguist exposes a functions for getting Github language stats by username & access token.

With default settings:

package main

import (
    "fmt"

	"github.com/stscoundrel/polylinguist"
)

accessToken := "YOUR_ACCESS_TOKEN"

// Fetches all languages from all repos.
stats, err := polylinguist.GetTopLanguages("YOUR_USERNAME", accessToken)

if err != nil {
    // However you want to deal with your errors.
    // Most likely cause: failed network, failed auth.
}

for index, language := range stats {
    fmt.Printf("%d. %s - %f - %s \n", index+1, language.Name, language.Percentage, language.Color)
}

With custom settings:

package main

import (
    "fmt"

	"github.com/stscoundrel/polylinguist"
	"github.com/stscoundrel/polylinguist/stats"
)

accessToken := "YOUR_ACCESS_TOKEN"

// Setup custom settings to skip certain languages & repos
// Also set custom aliases to combine some languages into single statistic.
settings := stats.Settings{
    IgnoredLanguages: []string{"SCSS", "CSS", "ASL", "HTML"},
    IgnoredRepos: []string{
        "old-norwegian-dictionary",
        "old-norwegian-dictionary-rs",
        "old-norwegian-dictionary-go",
    },
    AliasedLanguages: []stats.LanguageAlias{
        {
            Language: "C",
            Alias:    "C/C++",
        },
        {
            Language: "C++",
            Alias:    "C/C++",
        },
    },
}

stats, err := polylinguist.GetTopLanguagesWithSettings("YOUR_USERNAME", accessToken, settings)

if err != nil {
    // However you want to deal with your errors.
}

for index, language := range stats {
    fmt.Printf("%d. %s - %f - %s \n", index+1, language.Name, language.Percentage, language.Color)
}
