删除(Python)注释中的参差不齐的行

Question

PyCharm可以包装比某个数字n(在本例中=67(长的代码行，例如

# this is a really really really really really really really really really really really really really really long comment

成为

# this is a really really really really really really really really
# really really really really really really long comment

**是否有"相反"功能？*通常，由于在评论中添加和删除想法，它们最终看起来非常糟糕和破烂，如下所示：

# this is a the first idea.
# more bla bla, but still relating to first idea. bla bla.
# other bla bla.
# second brilliant idea. oh no, actually it breaks something, so watch out!

我希望 Pycharm(可能通过合并插件(能够重新格式化这些注释(填充最大行长(如下所示：

# this is a the first idea. more bla bla, but still relating to first 
# idea. bla bla. other bla bla. second brilliant idea. oh no, actually
# it breaks something, so watch out!

如果 Pycharm 没有这个，你知道一个文本处理器可以做到这一点吗？

Answer 1

默认情况下，这不能在 pycharm 中完成。没有这样的插件可用。您可以在类似的线程中看到答案

在 PyCharm 中使用换行符换行注释

现在要考虑以下选项

• 用 sed 或 awk 写一些东西，但这不会直接在 Windows 上工作
• 为 PyCharm 编写一个插件。这有一个巨大的学习曲线和太多的努力
• 编写脚本以执行所需的操作

我会选择最后一个选项，因为它是努力方面最快的解决方案。你可以选择你想要的语言，我选择Python，因为我们知道在格式化Python文件以在Pycharm中使用时会出现Python。

所以脚本的想法是合并连续注释，然后根据列宽将它们包装

起来

# this is a test
# this is a best.
# This could be even worst when this is not even good.
# Why should one do it using whatever they have done
import io, re
from textwrap import TextWrapper
import os
current_file = __file__
f = io.open(current_file, 'r')
comment_pattern = re.compile(r"^(s*)#(.*)")
in_comment = False

def spit_formatted_comments(initial_space, current_comment):
    if current_comment:
        wrapper = TextWrapper(initial_indent=initial_space + "#",
                              subsequent_indent=initial_space + "# ")
        wrapper.width = 80
        data = wrapper.wrap(" ".join(current_comment))
        print(os.linesep.join(data))

for line in f:
    match = comment_pattern.findall(line)
    if match:
        if not in_comment:
            in_comment = True
            current_comment = []
            initial_space = match[0][0]
        current_comment.append(match[0][1])
    elif in_comment:
        in_comment = False
        spit_formatted_comments(initial_space, current_comment)
        current_comment = []
        print(line, end='')
    else:
        print(line, end='')
spit_formatted_comments(initial_space, current_comment)
f.close()
# this is a last line comment to check border

相同的输出是

# this is a test  this is a best.  This could be even worst when this is not
# even good.  Why should one do it using whatever they have done

        wrapper.width = 80

        spit_formatted_comments(initial_space, current_comment)
        current_comment = []
        print(line, end='')
    else:

spit_formatted_comments(initial_space, current_comment)
f.close()
# this is a last line comment to check border
