Question

unterminated s＆＃39;使用El Capitan 10.11.3在我的MacBook上运行sed命令的命令`（不是操作系统版本与此问题有关）

我将diff-so-fancy与diff-highlight（python）一起使用。但我发现该问题位于format_diff_header() bash脚本中的diff-so-fancy函数中。我将在下面解释。当然，这个帖子也可能有其他原因。

当我运行命令时：git diff（并且当然在.gitconfig中配置diff命令以使用pager = diff-highlight | diff-so-fancy | less -r）

所以命令和错误：

$ git diff
sed: -e expression #1, char 259: unterminated \`s' command
sed: -e expression #1, char 273: unterminated \`s' command

以下git-so-fancy的完整脚本：

#!/bin/bash

###############
# diff-so-fancy builds on the good-lookin' output of diff-highlight to upgrade your diffs' appearances
#   * Output will not be in standard patch format, but will be readable
#   * No pesky `+` or `-` at line-stars, making for easier copy-paste.
#

#
#
# Usage
#
#   git diff | diff-highlight | diff-so-fancy
#
# Add to .gitconfig so all `git diff` uses it.
#   git config --global core.pager "diff-highlight | diff-so-fancy | less -r"
#
#
# Requirements / Install
#
# * GNU sed. On Mac, install it with Homebrew:
#       brew install gnu-sed --default-names  # You'll have to change below to `gsed` otherwise
# * diff-highlight. It's shipped with Git, but probably not in your $PATH
#       ln -sf "$(brew --prefix)/share/git-core/contrib/diff-highlight/diff-highlight" ~/bin/diff-highlight
# * Add some coloring to your .gitconfig:
#       git config --global color.diff-highlight.oldNormal "red bold"
#       git config --global color.diff-highlight.oldHighlight "red bold 52"
#       git config --global color.diff-highlight.newNormal "green bold"
#       git config --global color.diff-highlight.newHighlight "green bold 22"

[ $# -ge 1 -a -f "$1" ] && input="$1" || input="-"

color_code_regex=$'(\x1B\\[([0-9]{1,2}(;[0-9]{1,2})?)[m|K])?'
reset_color="\x1B\[m"
dim_magenta="\x1B\[38;05;146m"

format_diff_header () {
    # simplify the unified patch diff header
    sed -E "s/^($color_code_regex)diff --git .*$//g" | \
    sed -E "s/^($color_code_regex)index .*$/\
\1$(print_horizontal_rule)/g" | \
    sed -E "s/^($color_code_regex)\+\+\+(.*)$/\1\+\+\+\5\\
\1$(print_horizontal_rule)/g"
}

colorize_context_line () {
    # extra color for @@ context line
    sed -E "s/@@$reset_color $reset_color(.*$)/@@ $dim_magenta\1/g"
}

strip_leading_symbols () {
    # strip the + and -
    sed -E "s/^($color_code_regex)[\+\-]/\1 /g"
}

print_horizontal_rule () {
        printf "%$(tput cols)s\n"|tr " " "─"
}

# run it.
cat $input | format_diff_header | colorize_context_line | strip_leading_symbols

当我从上面脚本的最后一行中删除| format_diff_header时，错误消失了，但当然没有解决。

因此引发的错误：sed: -e expression #1: unterminated s＆＃39;命令`必须位于函数中的某个位置，再次在下面发布。

format_diff_header () {
    # simplify the unified patch diff header
    sed -E "s/^($color_code_regex)diff --git .*$//g" | \
    sed -E "s/^($color_code_regex)index .*$/\
\1$(print_horizontal_rule)/g" | \
    sed -E "s/^($color_code_regex)\+\+\+(.*)$/\1\+\+\+\5\\
\1$(print_horizontal_rule)/g"
}

欢迎所有建议！提前谢谢。
