stackoverflow

  • How do I force remove a package in Arch with pacman? - Unix & Linux Stack Exchange
    • 用 pacman -R 移除某個 package 的時候，如果有其他 package 相依於該 package 的話就無法移除
    • 如果仍要強制移除該 package 的話，有兩種解法：
      • pacman -Rd: 不管相依性，直接強制移除該 package。
      • pacman -Rc: 把該 package 跟所有相依於該 package 的 packages 全部一起移除掉（注意：會遞迴下去）。
  • git - How to cherry-pick multiple commits - Stack Overflow
    • git cherry-pick A..B
      • every commit after A up to and including B.
      • not include commit A.
    • git cherry-pick A^..B
      • include commit A.
    • Commit A should be older than commit B. If they're the wrong order the command will silently fail.

vim

  • Syntastic overrides let g:syntastic_python_checker = 'flake8 --ignore=E501' · Issue #204 · vim-syntastic/syntastic · GitHub
    • 用 syntastic 這個 vim plugin 遇到要改 Python linter 的問題，然後查到這個。
    • 要在 ‵vimrc‵ 裡頭用 ‵let g:syntastic_python_flake8_args = '--ignore=E501'‵ 這樣的寫法才有用
    • 然後 let g:syntastic_python_checkers = ["flake8","pep8","pyflakes","pylint"] 的順序會影響 syntastic 的運作
      • 按照順序來，只要其中一個沒安裝的話 syntastic 就會自動停止
      • 以這個設定來看的話，也就是只要沒有安裝 flake8 的話，syntastic 的 python syntax checking 就不會 work
      • 但如果全部都有安裝的話，就會照著這個順序一個一個檢查，所以把最常用的要擺在最前面
