setup_git.sh

takker.icon用gitの自動設定script

https://github.com/takker99/dotfiles/blob/v0.2.0/setup_git.bash

やること

GitHubで使うSSH鍵を生成する

takker99/dotfilesのclone

.gitconfigの設定

実行方法

パイプで流し込んだscript中にselect文があると壊れるので、一旦一時ファイルに書き込んでから実行している

code:sh

curl https://raw.githubusercontent.com/takker99/dotfiles/v0.2.0/setup_git.bash > temp.bash && bash temp.bash && rm temp.bash

実装メモ

https://github.com/takker99/dotfiles/blob/1798728f157a97df18bfa89e04533fc3a62304bd/setup.bash#L32 をベースに作り変える

例外処理を有効にする

code:setup_git.bash

set -eu

catch () {

echo "Some error have occurred. Terminate the installation."

}

trap catch ERR

変数設定

code:setup_git.bash

GITHUB_NAME="takker99"

GITHUB_EMAIL="37929109+takker99@users.noreply.github.com"

SSH_GITHUB_NAME="id_github_$GITHUB_NAME"

SSH_GITHUB_PATH="$HOME/.ssh/$SSH_GITHUB_NAME"

SSH_CONFIG_PATH="$HOME/.ssh/config"

SSH鍵を生成する

code:setup_git.bash

if ! -e "${SSH_GITHUB_PATH}" || ! -e "${SSH_GITHUB_PATH}.pub" ; then

echo "SSH keys for GitHub aren't found. Creating SSH keys..."

# 秘密鍵の中身を取り出す

copyKey() {

KEY=$(cat "${SSH_GITHUB_PATH}.pub")

if type "clip.exe" > /dev/null 2>&1; then

echo $KEY | clip.exe

else

echo $KEY | xsel

}

mkdir -p ~/.ssh

ssh-keygen -t ed25519 -C $GITHUB_EMAIL -f $SSH_GITHUB_PATH -P "" -N ""

公開鍵をコピーして、SSH鍵登録画面に貼り付けるよう指示する

貼り付け終わったら次に進む

select文 (bash)を使っている

パイプで流し込んだscript中にselect文があると壊れる

code:setup_git.bash

copyKey

echo "Copied the SSH public key to your clipboard. Please register it at https://github.com/settings/ssh/new"

select i in Registered CopyAgain

case $i in

Registered) break ;;

CopyAgain) echo "Copied again. Please register it" ; copyKey ;;

*) echo "$REPLY is an invalid value. Either \"1\" or \"2\" can be selected." ;;

esac

done

SSH通信を確認する

code:setup_git.bash

if ! -e $SSH_CONFIG_PATH ; then

cat << EOS >> $SSH_CONFIG_PATH

Host github github.com

User git

IdentityFile $SSH_GITHUB_PATH

HostName github.com

EOS

set errexit下でエラーを握りつぶす

code:setup_git.bash

ssh github || :

takker99/dotfilesをcloneする

code:setup_git.bash

if ! -d ~/git/dotfiles ; then

echo "Downloading takker99/dotfiles..."

mkdir -p ~/git

pushd ~/git

git clone git@github.com:takker99/dotfiles.git

popd

.gitconfigを設定する

code:setup_git.bash

if -e ~/.gitconfig ; then

mv ~/.gitconfig ~/.gitconfig_old

cat << EOS > ~/.gitconfig

user

email = $GITHUB_EMAIL

name = $GITHUB_NAME

gui

encoding = utf-8

core

editor = nvim

filemode = false

quotepath = false

grep

lineNumber = true
