使用Dimitrije Djekanovic授予 建议,这是当前 API 版本的工作版本 3.49(2022 年 5 月中旬):

/* hides the x image */
button.gm-ui-hover-effect > span {
  display: none !important;
}

/* inserts the customized and clickable image instead */
button.gm-ui-hover-effect {
  opacity: 1 !important;
  background: url('close.svg') center center !important;
  background-repeat: no-repeat !important;
  background-size: 16px 16px !important;
  /* above is a good size or uncomment the next line */
  /* background-size: contain !important; */
}

要对此进行测试,请转到 StackBlitz 演示,由 官方文档并粘贴style.css文件,同时将background更改为:

background: url('https://upload.wikimedia.org/wikipedia/commons/thumb/5/51/Mr._Smiley_Face.svg/414px-Mr._Smiley_Face.svg.png')
    center center !important;

output

Using what Dimitrije Djekanovic and Grant suggested, here is a working version for the current API version 3.49 (Mid-May of 2022):

/* hides the x image */
button.gm-ui-hover-effect > span {
  display: none !important;
}

/* inserts the customized and clickable image instead */
button.gm-ui-hover-effect {
  opacity: 1 !important;
  background: url('close.svg') center center !important;
  background-repeat: no-repeat !important;
  background-size: 16px 16px !important;
  /* above is a good size or uncomment the next line */
  /* background-size: contain !important; */
}

To test this, go to the StackBlitz demo provided by the official documentation and paste the style.css file while having background changed to:

background: url('https://upload.wikimedia.org/wikipedia/commons/thumb/5/51/Mr._Smiley_Face.svg/414px-Mr._Smiley_Face.svg.png')
    center center !important;

output

我的问题是:什么算作糟糕的代码

如果您无法给出什么是坏代码的正式定义,您就不能指望能够检测到它。因为这可能是你的问题的真正含义,所以我将提出我的答案 - 没有办法做到这一点。

即使是看似微不足道的事情,例如程序是否会终止也无法提前确定,我希望任何坏代码的定义都是无法终止的。

因此,在我看来,你有一个主要选择:信任你的用户(或者不信任他们并且不运行任何东西)。

否则,可能工作的方法是在严格的沙箱中运行脚本,如果脚本尚未完成运行,则在适当的时间后终止它。可接受的程度在很大程度上取决于您的具体情况。

My question to you: what counts as bad code?

If you cannot come up with a formal definition of what counts as bad code, you cannot hope to be able to detect it. And since this is probably what your question really meant, I'll put forward my answer - there's no way to do it.

Even a seemingly trivial thing such as whether a program will terminate or not cannot be determined ahead of time, and I'd expect any definition of bad code would be something that couldn't terminate.

Thus to my mind you have one major option: trust your users (or alternatively don't trust them and don't run anything).

Something that might work otherwise is to run the script in a strict sandbox, and terminate it after an appropriate amount of time if it hasn't already finished running. It very much depends on your circumstances as to what is acceptable.

如果您正在寻找速度,我会推荐 Ox 因为它几乎是现有选项中最快的选项提及。

我使用 omg.org/spec
这些是结果(以秒为单位):

xml = File.read('path_to_file')
Ox.parse(xml).to_json                    --> @real=44.400012533
Crack::XML.parse(xml).to_json            --> @real=65.595127166
CobraVsMongoose.xml_to_hash(xml).to_json --> @real=112.003612029
Hash.from_xml(xml).to_json               --> @real=442.474890548

If you're looking for speed I would recommend Ox since it's pretty much the fastest option from the ones already mentioned.

I ran some benchmarks using an XML file that has 1.1 MB from omg.org/spec
and these are the results(in seconds):

xml = File.read('path_to_file')
Ox.parse(xml).to_json                    --> @real=44.400012533
Crack::XML.parse(xml).to_json            --> @real=65.595127166
CobraVsMongoose.xml_to_hash(xml).to_json --> @real=112.003612029
Hash.from_xml(xml).to_json               --> @real=442.474890548

您可以打开详细开关来检查整个日志,并 grep 您要查找的目录以及删除标志和 grep 修订号:

svn log -v | grep -i -e "   D /path/to/folder" -e "^r[0-9]" | more

第二个选项是通过“猜测”来检查文件 itelf 上的日志(带或不带详细开关)修订号,例如,

svn log svn://repository/deleted/directory -r1337 -v --limit 1

以上两种方法都不是好方法,但它们可以解决问题。

You can check entire log with verbose switch on and grep the directory you are looking for together with delete flag and grep revision numbers as well:

svn log -v | grep -i -e "   D /path/to/folder" -e "^r[0-9]" | more

Second option is to check the log (with or without verbose switch) on the file itelf by "guessing" revision numbers, for example

svn log svn://repository/deleted/directory -r1337 -v --limit 1

Neither of above are nice approaches, but they will do the trick.

一个疯狂的猜测...图像是 IDisposable。你是在循环中调用这个还是什么?尝试将图像本身放入 using() 块中?

A wild guess... Image is IDisposable. Are you calling this in a loop or something? Try putting your Image itself in a using() block?

当字段获得焦点时,Mac 将选择文本字段的内容。如果监听焦点更改事件,则可以恢复文本字段的状态。

// JTextField linkedText
// Cache the state of the JTextField prior to requesting focus
final int
  startBefore = linkedText.getSelectionStart(),
  endBefore = linkedText.getSelectionEnd();
linkedText.requestFocus(); // this was the original code line!

// Use a focus listener to listen for the focus change and then
// reset the selected text to protect the cursor position
linkedText.addFocusListener ( new FocusListener()
{
    public void focusGained( FocusEvent event ) {
        linkedText.setSelectionStart( startBefore );
        linkedText.setSelectionEnd( endBefore );
    }

    public void focusLost( FocusEvent event ) {
        // do nothing
    }
} );

Mac will select the contents of the text field when the field gains focus. You can restore the state of the text field if you listen for the focus change event.

// JTextField linkedText
// Cache the state of the JTextField prior to requesting focus
final int
  startBefore = linkedText.getSelectionStart(),
  endBefore = linkedText.getSelectionEnd();
linkedText.requestFocus(); // this was the original code line!

// Use a focus listener to listen for the focus change and then
// reset the selected text to protect the cursor position
linkedText.addFocusListener ( new FocusListener()
{
    public void focusGained( FocusEvent event ) {
        linkedText.setSelectionStart( startBefore );
        linkedText.setSelectionEnd( endBefore );
    }

    public void focusLost( FocusEvent event ) {
        // do nothing
    }
} );

  1. 考虑使用 CPANPLUS(cpanp 脚本)而不是 CPAN。
  2. 考虑在安装其他任何东西之前安装 YAML。
  3. 考虑将配置设置为遵循先决条件(即,当某些包需要当前缺少的其他模块时,它将继续并安装其他模块 - 根据需要递归地安装)。
  1. Consider using CPANPLUS (cpanp script) instead of CPAN.
  2. Consider installing YAML before installing anything else.
  3. Consider setting the configuration to follow prerequisites (that is, when some package requires some other module that is currently missing, it will go ahead and install the other module - recursively as necessary).

为什么CPAN.pm升级失败?

这不是范围的问题,而是不同流程的问题。 Parallel::ForkManager 使用 fork()(因此得名)。这意味着并行运行的每个版本实际上是一个单独的进程(perl 解释器的单独调用),因此是单独的内存。每个进程中的变量将具有相同的名称,但它们不会指向内存中的同一位置。

如果您想在并行工作线程之间共享变量,那么您需要考虑使用线程(我不推荐)或使用某种 IPC(进程间通信),例如 IPC::Shareable

It's not a matter of scoping, it's a matter of different processes. Parallel::ForkManager uses fork() (hence the name). This means that each version running in parallel is actually a separate process (a separate invocation of the perl interpreter) and thus separate memory. The variables will have the same name in each process, but they won't point to the same place in memory.

If you want to share variables across parallel workers, then you'll need to look at either using threads (which I wouldn't recommend) or using some sort of IPC (inter-process communication) like IPC::Shareable

唯一真正了解的方法是对它们进行分析,这实际上是该问题的唯一答案。自 context 以来的第一次性能将会受到轻微影响当它是一个元素而不是一个 jQuery 对象时效果最好

The only real way to know is to profile them, that is really the only answer that can be given to the question. There will be a slight performance hit with the first since context works best when it is an element and not a jQuery object.

您正在考虑哪种 RPC?如果是 XML-RPC,那么 Python 带有 SimpleXMLRPCServer 模块,那么, ,允许您用 Python 编写 RPC 服务器。

如果远程服务器使用DCOM,则可以使用PythonCOM

What kind of RPC are you thinking of? If it is XML-RPC, then Python comes with the SimpleXMLRPCServer module, which, well, allows you to write RPC servers in Python.

你可以做这样的事情。 (有关 SetTop、SetLeft,请参阅 MSDN 文档)

// add control to children collection 
// (ctlToAdd can be TextBlock, RichTextBox, FlowDocument for example
inkCanvas.Children.Add(ctlToAdd);
InkCanvas.SetTop(ctlToAdd, 100.0);
InkCanvas.SetLeft(ctlToAdd,100.0);

You can do something like this. (See MSDN docs for SetTop, SetLeft)

// add control to children collection 
// (ctlToAdd can be TextBlock, RichTextBox, FlowDocument for example
inkCanvas.Children.Add(ctlToAdd);
InkCanvas.SetTop(ctlToAdd, 100.0);
InkCanvas.SetLeft(ctlToAdd,100.0);

如何使用代码向 inkcanvas 添加文本?
