prのタイトルを取得できるcliをgolangで作った

🔧🛠️👨‍🔧技術

成果

github.com

こんな風に使う

function rep(){
  if [[ $@ = "d" ]]; then
    base="develop"
  elif [[ $@ = "m" ]]; then
    base="master"
  else
    base=$@
  fi
  org=$(basename $(dirname "$PWD"))
  branch=$(currentBranch)
  repo=$(basename "$PWD")
  go-get-repo-info -status open -org $org -branch $branch -base $base -repo $repo
}

\nを除去する

qiita.com

\nが入ってきたので除去

var regxNewline = regexp.MustCompile(`\r\n|\r|\n`) //throw panic if fail

func convNewline(str, nlcode string) string {
    return regxNewline.Copy().ReplaceAllString(str, nlcode)
}

file読み込み

qiita.com

func useIoutilReadFile(fileName string) string {
    bytes, err := ioutil.ReadFile(fileName)
    if err != nil {
            panic(err)
    }

    return string(bytes)
}

home directore 取得(~/)

   usr, _ := user.Current()
    f := strings.Replace("~/go-get-repo-info-access-token",  "~", usr.HomeDir, 1)

    accessToken := useIoutilReadFile(f)
    regexedAccessToken := convNewline(accessToken, "")

    if accessToken == "" {
        panic("access-token is blank. create go-get-repo-info/access-token. and write access-token. not \\n")
    }

go-github

github.com

    var (
        status = flag.String("status", "open", "open|close|all" )
        organization = flag.String("org", "kajirikajiri", "ex)kajirikajiri" )
        branch = flag.String("branch", "", "ex}feature/issue-700" )

    flag.Parse()

    ctx := context.Background()
    ts := oauth2.StaticTokenSource(
        &oauth2.Token{AccessToken: regexedAccessToken},
    )
    tc := oauth2.NewClient(ctx, ts)

    client := github.NewClient(tc)

    opts := &github.PullRequestListOptions{*status, *organization + ":" + *branch, *base, *sort, *direction, github.ListOptions{Page: 1}}

    pulls, _, err := client.PullRequests.List(ctx, *organization, *repo, opts)
    if err != nil {
        fmt.Print(err)
    }

    for _ ,pull := range pulls {
        fmt.Print(*pull.Title)
    }

import でつまる

v31の方でimportしたら使えなかった

import "github.com/google/go-github/v31/github"   // with go modules enabled (GO111MODULE=on or outside GOPATH)
import "github.com/google/go-github/github" // with go modules disabled

pointerの扱いにつまる

    fmt.Print(*pull.Title)

*pull.Titleが なかなかわからなかった 公式サイトで確認した
