git 的稀疏检出和部分克隆

参考文章：Bring your monorepo down to size with sparse-checkout

1. 本地已有仓库

   $ git sparse-checkout set client/android
    
   $ ls
   bootstrap.sh*  client/  LICENSE.md  README.md
    
   $ ls client/
   android/
    
   $ find . -type f | wc -l
   62

2. 克隆远程仓库时，稀疏检出和部分克隆

   $ git clone --filter=blob:none --no-checkout <https://github.com/derrickstolee/sparse-checkout-example>
   Cloning into 'sparse-checkout-example'...

   $ cd sparse-checkout-example/
    
   $ git sparse-checkout set --cone
    
   $ git checkout main

   Your branch is up to date with 'origin/main'.
    
   $ git sparse-checkout set client/android
   remote: Enumerating objects: 3, done.
   remote: Counting objects: 100% (3/3), done.
   remote: Compressing objects: 100% (3/3), done.

   Receiving objects: 100% (26/26), 985.91 KiB | 13.69 MiB/s, done.

   如果检出多个目录，使用git sparse-checkout set client/android web/browser

3. 使用脚本 bootstrap.sh

   #!/bin/bash -e
    
   SCRIPTNAME=$0
   die() {
   echo "$SCRIPTNAME: $1"
   exit 1
   }
    
   TEAM=$1
    
   case $TEAM in
   "content")
   FOLDERS="content templates quartz"
   ;;
   *)
   die "please specify a valid team"
   ;;
   esac
    
   echo "Running 'git sparse-checkout init --cone'"
   git sparse-checkout init --cone
    
   echo "Running 'git sparse-checkout set $FOLDERS'"
   git sparse-checkout set $FOLDERS
