仅为新文件启用SwiftLint

Question

我有一个非常大的iOS(遗留)项目，我想在其中添加SwiftLint。所有我希望执行的规则，我只会在新创建的文件上执行。通过这种方式，我不必回去解决所有可能出现的问题，因为过去没有遵循这些规则(因为没有使用SwiftLint )。我不确定如何实现这一点？

您可以像这样运行脚本

    # Run SwiftLint
    START_DATE=$(date +"%s")
    
    SWIFT_LINT=/usr/local/bin/swiftlint
    
    # Run SwiftLint for given filename
    run_swiftlint() {
        local filename="${1}"
        if [[ "${filename##*.}" == "swift" ]]; then
            #${SWIFT_LINT} autocorrect --path "${filename}"
            ${SWIFT_LINT} lint --path "${filename}"
        fi
    }

    if [[ -e "${SWIFT_LINT}" ]]; then
        echo "SwiftLint version: $(${SWIFT_LINT} version)"
        # Run for both staged and unstaged files
        git diff --name-only | while read filename; do run_swiftlint                 "${filename}"; done
        git diff --cached --name-only | while read filename; do                 run_swiftlint "${filename}"; done
    else
        echo "${SWIFT_LINT} is not installed."
        exit 0
    fi

    END_DATE=$(date +"%s")

    DIFF=$(($END_DATE - $START_DATE))
    echo "SwiftLint took $(($DIFF / 60)) minutes and $(($DIFF % 60)) seconds to complete."

只需使用以下代码将构建阶段运行脚本添加到Xcode

"${SRCROOT}/Scripts/swiftlint.sh"

它来自这里https://github.com/realm/SwiftLint/issues/413#issuecomment-184077062

它在M1芯片上不起作用，因为你需要这样说

if test -d "/opt/homebrew/bin/"; then
  PATH="/opt/homebrew/bin/:${PATH}"
fi

export PATH

if which swiftlint >/dev/null; then
  swiftlint
else
  echo "warning: SwiftLint not installed, download from https://github.com/realm/SwiftLint"
fine
