将正则表达式 git diff split words at punctuation into .gitconfig file
putting regex to make git diff split words at punctuation into .gitconfig file
当前设置
我的 .gitconfig 当前包含此别名：
[alias]
wdiff = diff --color-words --histogram
让我写 git wdiff 并逐字而不是逐行 diff 输出。我用它来用 LaTeX 写学术散文。
目标
此方法只在白色处分词space。我想在标点符号处进行划分，例如，last word of sentence. 更改为 last word of sentence.\footnote{New footnote.} 会产生 diff 输出，看起来像这样：
last word of sentence.\footnote{New footnote.}
而不是当前输出：
last word of sentence.sentence.\footnote{New footnote.}
（斜体表示删除，粗体表示添加）。
尝试的解决方案
我发现 以一个正则表达式开头，它完全符合我在命令行中的要求，但我还没有想出如何将它放入我的 .gitconfig 文件而不生成错误消息 fatal: bad config line 12 in file /Users/alex/.gitconfig。这是我放入 .gitconfig 文件的内容：
[alias]
wdiff = diff --color-words='[^][<>()\{},.;:?/|\=+*&^%$#@!~`"'\''[:space:]]+|[][<>(){},.;:?/|\=+*&^%$#@!~`"'\'']' --histogram
好像是分号的问题。
处理 .gitconfig 中类似问题的 different question 建议在整个别名周围加上双引号。但是当我在我的例子中这样做时，我得到了同样的错误信息。我认为这是因为正则表达式还包含双引号。
问题
如何将正则表达式放入我的 .gitconfig 文件中以便正确解析它？
在找到this page of documentation之前，我也很困惑。您感兴趣的部分是：
A line that defines a value can be continued to the next line by ending it with a \; the backslash and the end-of-line are stripped. Leading whitespaces after name =, the remainder of the line after the first comment character # or ;, and trailing whitespaces of the line are discarded unless they are enclosed in double quotes. Internal whitespaces within the value are retained verbatim.
Inside double quotes, double quote " and backslash \ characters must be escaped: use \" for " and \ for \.
The following escape sequences (beside \" and \) are recognized: \n for newline character (NL), \t for horizontal tabulation (HT, TAB) and \b for backspace (BS). Other char escape sequences (including octal escape sequences) are invalid.
因此，.git/config 中的正确别名是：
wdiff = "diff --color-words='[^][<>()\{},.;:?/|\\=+*&^%$#@!~`\"'\''[:space:]]+|[][<>(){},.;:?/|\\=+*&^%$#@!~`\"'\'']' --histogram"
在这种情况下，您只需将所有内容括在双引号中并转义 " 和反斜杠。
