一些开发用半自动化脚本

动机

• 准备阶段，把 cd ~/s<TAB> asp checkout name cd name/r<TAB>/<TAB> vim PKGBUILD 缩成一个命令
• 修包阶段，把 updpkgsums extra-riscv64-build 参数我忘了 缩成一个命令
• 提交阶段，把 git diff > riscv64.patch vim riscv64.patch cd ~/ar<TAB> git checkout -b name mkdir name cp ~/so<TAB>/name/r<TAB>/<TAB>/ri<TAB> name cd name ga gm gp -u origin name 缩成一个命令

在开始之前

可以根据自己的环境和需求来修改：

1. gib.sh 中的源码路径 ~/src
2. build 用的临时文件夹 ~/pkg
3. 你自己的 archriscv-packages 的 fork 所在的路径 ~/archriscv-packages

   sudo pacman -Sy asp devtools-riscv64  # -Syu & reboot first, if necessary
   cd ~
   mkdir src pkg
   git clone [email protected]:$USERNAME/archriscv-packages.git
   cd archriscv-packages
   git remote add upstream https://github.com/felixonmars/archriscv-packages.git

4. 其它

准备工作

mkdir ~/.bin
touch ~/.bin/prepare.sh
touch ~/.bin/gib.sh  # 这里 gib 取的是加拿大口音的 give
chmod +x ~/.bin/*.sh
mkdir ~/src ~/pkg

同时请确保 ~/prepare_tmp_dir 不存在，并且 ~/.bin 不在 你的 $PATH 环境变量中。

用法

1. （在任意目录，拉取源码）gib rocksdb
2. （在 repos/* 目录，生成 diff 并 push 到新的 branch）push .（但实际上 commit 和 push 操作需要你手动确认）
3. （在 repos/* 目录，尝试 build）rv64build

部署

• ~/.bashrc

# append
alias rv64build="extra-riscv64-build -- -d ~/pkg:/var/cache/pacman/pkg"  # 这里 ~/pkg 按环境配置可以替换成任意空文件夹
alias nohuprv64build="nohup extra-riscv64-build -- -d ~/pkg:/var/cache/pacman/pkg &"
alias prep=". ~/.bin/prepare.sh"  # alias 可以随便改
alias gib=". ~/.bin/gib.sh"

• ~/.bin/gib.sh

else
  echo "No existing riscv64 patch file found."

# 将第一个 x86_64（`arch=(x86_64)`）换成 riscv64 并保留格式，如果 arch 是 any 则不改
