取消折叠多行函数调用 [英] Uncrustify Collapse Multiline Function Call

问题描述

我有看起来像这样的函数调用(没有明显的原因):

I have function calls that look like this (for no apparent reason):

func
(
    a,
    b,
    c
)

有没有一种方法可以使函数不生锈地将其折叠成一行?我已经尝试了两天了，没有断断续续...

Is there a way to make uncrustify collapse the function into a single line? I have been trying for two days not on and off...

我知道它可以用于函数声明，但是我不能让它用于函数调用.

I got it to work for function declarations, but I don't get it to work for function calls.

在我们遇到的同时，我也有一些看起来像这样的函数:

While we are at it I also have functions that look like so:

func
(
    a, // (IN) the A
    b, // (IN) something b
    c  // (OUT) the resulting value
)

有没有办法在不破坏代码的情况下处理这种情况?由于unrustify会保留评论，因此我认为这是不可能的.使用函数声明，它将其折叠到第一个注释.

Is there a way to handle that case too, without breaking the code? Since uncrustify keeps comments, I think this is kind of impossible. With function declarations it collapses it to the first comment.

推荐答案

经过一些深入的研究，我得出了一个结论，那就是，无法进行修饰不能做到这一点.为了我的目的，我一起砍了一个小的perl脚本:

After some LOOONG research I have come to the conclusion, that uncrustify can't do that. For my porposses I hacked a small perl script together:

$filename = $ARGV[0];

{
    open(FILE, "<", $filename) or die "Cant open $filename for reading\n";
    local $/ = undef;
    $lines = <FILE>;
    close(FILE);
}

# squash comments in function calls and declarations
$lines =~ s/,[ \t]*\/\/[^\n\r]*/,/gm;
# squash last comment in function calls and declarations
$lines =~ s/[ \t]*\/\/[^\n\r]*\r\n[ \t]*\)/\)/gm;
# squash newlines at the start of a function call or declaration
$lines =~ s/\([ \t]*\r\n[ \t]*/\(/gm;
# squash newlines in function calls and declarations
$lines =~ s/,[ \t]*\r\n[ \t]*/, /gm;
# squash the last newline in a function call or declaration
$lines =~ s/[ \t]*\r\n[ \t]*\)/\)/gm;

{
    open(FILE, ">", $filename) or die "Cant open $filename for writing\n";
    print FILE $lines;
    close(FILE);
}

我会研究是否可以构建将该功能集成到unustify中的补丁.

I will look into if I can build a patch that integrates that feature into uncustify.
