How to ignore multiple lines of code in the same file type using gitattribute and git config?
问题
以下是您要翻译的内容：
作为对这个帖子的扩展：Git是否可以忽略特定行？，我试图忽略同一文件类型中的多行。
是否有以下方式：
- 为相同的文件或文件类型在同一个
.gitattributes筛选器上设置多个筛选器？（如下所示）或
*.rs filter=filterA
*.rs filter=filterB
// 类似于
*.rs filter=filterA + filterB
- 在
.git/config中为同一个筛选器添加多个规则？（如下所示）
[filter "filterA"]
clean = sed "/abc/d"
[filter "filterB"]
clean = sed "/def/d"
// 类似于
[filter "filterC"]
clean = sed "/abc/d"
clean = sed "/def/d"
上述内容导致.gitattributes中的最后一个筛选器覆盖了从第一个筛选器进行的更改。我还尝试过类似于clean = sed "/abc*def/d"，但这并没有起作用。
英文:
As an extension of this post: Can git ignore a specific line?, I am trying to ignore multiple lines in the same file type.
Is there a way to either;
- set multiple filters to the same
.gitattributesfilter for the same file or file types? (like below) OR
*.rs filter=filterA
*.rs filter=filterB
// to something like
*.rs filter=filterA + filterB
- add multiple rules to the same filter in
.git/config? (like below)
[filter "filterA"]
clean = sed "/abc/d"
[filter "filterB"]
clean = sed "/def/d"
// to something like
[filter "filterC"]
clean = sed "/abc/d"
clean = sed "/def/d"
The above causes the last filter in .gitattributes to overwrite the changes made from the first filter. I have also attempted something like clean = sed "/abc*def/d", but this did not work.

如果您想忽略整行，我的建议是使用grep -v而不是sed //d。链接问题中的答案使用了sed，因为它只隐藏了行的部分，这正是sed适合的任务。
所以首先让我们重写您的两个简单过滤器：
[filter "filterA"]
clean = grep -v "abc"
[filter "filterB"]
clean = grep -v "def"
请注意，如果您的占位符abc和def包含正则表达式元字符，您需要使用反斜杠进行转义。例如，\* - grep会将其解释为字面上的星号，而*是一个元字符。请参阅man grep。
现在来处理更复杂的过滤器：将这两个表达式组合成一个复杂的正则表达式：
[filter "filterC"]
clean = grep -v "abc\|def"
\|用于在基本（默认）grep语法中分隔正则表达式的分支。在扩展的正则表达式中，语法如下：
[filter "filterC"]
clean = grep -Ev "abc|def"
英文:
If you want to ignore entire lines my advice is to use grep -v instead of sed //d. The answers at the linked question use sed because they hide only parts of lines, a task for which sed is exactly suitable.
So 1st lets rewrite your two simple filters:
[filter "filterA"]
clean = grep -v "abc"
[filter "filterB"]
clean = grep -v "def"
Please be warned that if your placeholders abc and def contain regular expression metacharacters you need to escape them using backslash. Like \* — grep interprets this as a literal asterisk while * is a metacharacter. See man grep.
Now to the more complex filter: combine the two expressions into one complex regular expression:
[filter "filterC"]
clean = grep -v "abc\|def"
\| separates branches in regular expressions in basic (default) grep syntax. In case of extended RE the syntax is
[filter "filterC"]
clean = grep -Ev "abc|def"
