Question

也许我错过了什么，但仍然没有找到这样的设置。正式地说clang-format没有生成正确的UNIX文本文件，因为最后一行总是缺少EOL字符。

选项 1：

发现和外部参考。这可以帮助您，“您可以递归地添加 EOL 字符/清理来自 here... 的文件”

git ls-files -z "*.cpp" "*.hpp" | while IFS= read -rd '' f; do tail -c1 < "$f" | read -r _ || echo >> "$f"; done

说明：

git ls-files -z "*.cpp" "*.hpp" //lists files in the repository matching the listed patterns. You can add more patterns, but they need the quotes so that the * is not substituted by the shell but interpreted by git. As an alternative, you could use find -print0 ... or similar programs to list affected files - just make sure it emits NUL-delimited entries.

while IFS= read -rd '' f; do ... done //iterates through the entries, safely handling filenames that include whitespace and/or newlines.

tail -c1 < "$f" reads the last char from a file.

read -r _ exits with a nonzero exit status if a trailing newline is missing.

|| echo >> "$f" appends a newline to the file if the exit status of the previous command was nonzero.

来自 Clang format script 的选项 2：

#!/bin/bash

set -e

function append_newline {
    if [[ -z "$(tail -c 1 "$1")" ]]; then
        :
    else
        echo >> "$1"
    fi
}

if [ -z "$1" ]; then
    TARGET_DIR="."
else
    TARGET_DIR=$1
fi

pushd ${TARGET_DIR} >> /dev/null

# Find all source files using Git to automatically respect .gitignore
FILES=$(git ls-files "*.h" "*.cpp" "*.c")

# Run clang-format
clang-format-10 -i ${FILES}

# Check newlines
for f in ${FILES}; do
    append_newline $f
done

popd >> /dev/null

如何指示clang-format在文件末端添加EOL-character？
