Exuberant-ctags 错误地标记了 python 多行类定义

Question

当 python 类定义跨越多行时 Exuberant-ctags 生成错误的标签，只有最后一行进入搜索模式：

考虑文件test.py：

class FirstSubclass(

    LongLineBaseClass, AnotherLongClassName,

    MoreBaseClassWithVeryLongName

):

    pass

class SecondSubclass(

    LongLineBaseClass, AnotherLongClassName,

    MoreBaseClassWithVeryLongName

):

    pass

class OneLineClass(LongLineBaseClass):

    pass

和生成的tags文件ctags test.py（添加评论）：

FirstSubclass   test.py /^):$/;"    c !PROBLEM

OneLineClass    test.py /^class OneLineClass(LongLineBaseClass):$/;"    c !OK

SecondSubclass  test.py /^):$/;"    c !PROBLEM

两者都FirstSubclass接收SecondSubclass到相同的搜索模式（ex command）：/^):$即每个类定义的最后一行只有两个字符。这使得在 vim 中导航的标签无法使用。

旺盛的 ctags 版本和信息：

我尝试过的：language-python kinds我使用了带和不带, 参数的 ctags，什么都没有。

有任何想法吗 ？提前致谢。

Universal-ctags ( https://ctags.io ) 是 Exuebrante-ctags 的非官方分支，可以提取预期的模式：[yamato@slave]~% cat /tmp/foo.py&nbsp;cat /tmp/foo.py&nbsp;class FirstSubclass(&nbsp; &nbsp; LongLineBaseClass, AnotherLongClassName,&nbsp; &nbsp; MoreBaseClassWithVeryLongName):&nbsp; &nbsp; passclass SecondSubclass(&nbsp; &nbsp; LongLineBaseClass, AnotherLongClassName,&nbsp; &nbsp; MoreBaseClassWithVeryLongName):&nbsp; &nbsp; passclass OneLineClass(LongLineBaseClass):&nbsp; &nbsp; pass[yamato@slave]~% u-ctags -o - /tmp/foo.pyu-ctags -o - /tmp/foo.pyFirstSubclass&nbsp; &nbsp;/tmp/foo.py /^class FirstSubclass($/;"&nbsp; cOneLineClass&nbsp; &nbsp; /tmp/foo.py /^class OneLineClass(LongLineBaseClass):$/;"&nbsp; &nbsp; cSecondSubclass&nbsp; /tmp/foo.py /^class SecondSubclass($/;" c此外，它可以填充继承字段：[yamato@slave]~% u-ctags --fields=+i -o - /tmp/foo.pyu-ctags --fields=+i -o - /tmp/foo.pyFirstSubclass&nbsp; &nbsp;/tmp/foo.py /^class FirstSubclass($/;"&nbsp; c&nbsp; &nbsp;inherits:LongLineBaseClass, AnotherLongClassName, MoreBaseClassWithVeryLongName&nbsp;OneLineClass&nbsp; &nbsp; /tmp/foo.py /^class OneLineClass(LongLineBaseClass):$/;"&nbsp; &nbsp; c&nbsp; &nbsp;inherits:LongLineBaseClassSecondSubclass&nbsp; /tmp/foo.py /^class SecondSubclass($/;" c&nbsp; &nbsp;inherits:LongLineBaseClass, AnotherLongClassName, MoreBaseClassWithVeryLongName&nbsp;
