这是一个简单的解决方案,只需旋转进度条即可

Here is a simple solution, just rotate your progress bar

我不知道有任何数据序列化语言可以满足您的所有这些要求。

我非常喜欢 JSON 和 OGDL(因为它们比 XML 更容易阅读),但它们(至少)都无法允许继承。

PS:维基百科此处对流行数据格式进行了比较。

PPS:我想你应该考虑编写一个 DSL内部(或)实现并不难实现,您可以使用 Python 本身作为宿主语言。

I don't know of any data serialization language that satisfies all of those requirements of yours.

I'm very fond of JSON and OGDL (because they are much easier to read then XML), but they both fail (at least) in allowing inheritance.

PS: Wikipedia has a comparison of popular data formats here.

PPS: I guess you should consider writing a DSL. A internal (or weak) implementation would not be that hard to implement, and you could use Python itself as the host language.

这适用于输出 XML,但我仍然不知道如何输出 HTML:

(defn dom->xml
  "serialize a dom element back to XML text"
  [elem]
  (let [sw (java.io.StringWriter.)]
    (.serialize
     (org.apache.xml.serialize.XMLSerializer. 
      sw (org.apache.xml.serialize.OutputFormat.))
     elem)
    (str sw)))

This works for outputting XML, but I still don't know how to output HTML:

(defn dom->xml
  "serialize a dom element back to XML text"
  [elem]
  (let [sw (java.io.StringWriter.)]
    (.serialize
     (org.apache.xml.serialize.XMLSerializer. 
      sw (org.apache.xml.serialize.OutputFormat.))
     elem)
    (str sw)))

您可以将包含第一个单元格内容的 UIView 放置在 UITableView 的顶部。当您填充单元格时,您应该将第一个单元格留空(它将被初始位置的固定 UIView 覆盖)。

You can place the UIView with the content of the first cell on top of the UITableView. When you fill up the cells you should leave the first cell empty (it will be covered by the fixed UIView in the initial position).

sed -i.bak -r 's/page-([0-9]+)/apple-\1.html/' file

sed  's/page-\([0-9][0-9]*\)/apple-\1.html/' file > t && mv t file

除了sed之外,你还可以使用gawk的gensub()

awk '{b=gensub(/page-([0-9]+)/,"apple-\\1.html","g",$0) ;print b  }' file
sed -i.bak -r 's/page-([0-9]+)/apple-\1.html/' file

sed  's/page-\([0-9][0-9]*\)/apple-\1.html/' file > t && mv t file

Besides sed, you can also use gawk's gensub()

awk '{b=gensub(/page-([0-9]+)/,"apple-\\1.html","g",$0) ;print b  }' file

Ruby — 52

s=?1;loop{puts s;s.gsub!(/(.)\1*/){"#{
amp;.size}"+$1}}

任务太简单了,也太没用了……

如果您使用的是NServiceBus V3,您可以查看IMutateOutgoingMessages和IMutateIncomingMessages接口。

或者,如果您想让消息按特定顺序通过处理程序,请查看此链接:

If you are using NServiceBus V3, you can take a look at the IMutateOutgoingMessages and IMutateIncomingMessages interfaces.

我记得在 sourceforge 上读过一些关于 Cppunit 2 设计的讨论 维基。我会从这里开始。此外,Noel Llopis 探索了 C++ 单元测试框架丛林

但是,你是说你想重新创建另一个框架,而你只剩下很少的时间了。我建议选择一个适合您单元测试需求的框架,看看它是否可以用于您的 MVC 和数据测试。此外,单元测试框架并不是为了运行性能测试而设计的。我建议遵循 Unix 哲学:做一件事并且做得很好的简单小工具

I remember having read some discussions about Cppunit 2 design on the sourceforge wiki. I'd start from here. Also, Noel Llopis explored the C++ unit-testing framework jungle.

But, you're saying you want to re-create another framework and you only have few time left. I'd suggest picking one framework fitting your need for the unit tests, see if it can be used fore your MVC and data testing. Moreover unit testing framework are not designed to run performance tests. I'd recommend following the Unix philosophy here: simple little tools that do one thing and do it well.

您可以向我提供哪些文档(、链接和建议)来创建测试库?

从空行中删除空格的简单替代方法:

  1. TextFX>TextFX Edit>修剪尾随空格

这将删除所有尾随空格,包括空行中的尾随空格。
确保尾随空格不重要。

An easy alternative for removing white space from empty lines:

  1. TextFX>TextFX Edit> Trim Trailing Spaces

This will remove all trailing spaces, including trailing spaces in blank lines.
Make sure, no trailing spaces are significant.

对我来说听起来像是策略模式的候选者。您可能需要一个带有 PerformAction 方法的 WorkerAction 抽象类。然后 WorkerAction 类的子类将实现诸如砍树、挖金子和其他工人操作等细节。因此,子类了解树的详细信息,并且可以在树上调用必要的方法来影响正在被砍伐的树。

然后,worker 类只需要对其调用performAction() 的具体WorkerAction 实例的引用。工作人员不知道树或黄金等的详细信息。这样工作人员可以执行该操作,但您不会将工作人员限制为只能执行一项操作。事实上,如果您希望您的工作人员将来执行更多操作,您不再需要修改工作人员类。

Sounds like a candidate for the Strategy pattern to me. You may need a WorkerAction abstract class with a performAction method. Then subclasses of the WorkerAction class will implement the details such as cutting a tree, digging for gold and other worker actions. So the sub class knows about the details of the tree and can call the necessary methods on the tree to affect the tree as it is being cut.

The worker class then only need a reference to an instance of a concrete WorkerAction on which it calls performAction(). The worker does not know the details of the Tree or the Gold etc. This way the worker can perform the action but you are not limiting the worker to only one action. In fact you no longer need to modify the worker class if you want your worker to do more actions in the future.

您可以在表单字段中设置标签值:

myfield = forms.MultipleChoiceField(label='Select any of the following')

You can set the label value in your form field:

myfield = forms.MultipleChoiceField(label='Select any of the following')

使用 PHPExcel

include 'PHPExcel/IOFactory.php';

$objReader = PHPExcel_IOFactory::createReader('CSV');

// If the files uses a delimiter other than a comma (e.g. a tab), then tell the reader
$objReader->setDelimiter("\t");
// If the files uses an encoding other than UTF-8 or ASCII, then tell the reader
$objReader->setInputEncoding('UTF-16LE');

$objPHPExcel = $objReader->load('MyCSVFile.csv');
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
$objWriter->save('MyExcelFile.xls');

initMouseEvent 现已弃用,请使用它:

let e = new MouseEvent('mousedown', {
  bubbles: true,
  cancelable: true,
  view: window
})
element.dispatchEvent(e)

initMouseEvent is deprecated now, use this instead:

let e = new MouseEvent('mousedown', {
  bubbles: true,
  cancelable: true,
  view: window
})
element.dispatchEvent(e)

@snemarch 基本上是正确的,尽管我认为他和文档都错误地认为 ILT 和 IAT 在磁盘上是相同的。我查看了字节,它们不一样。

不过,他对表格的定义和目的的看法是正确的。

Windows Loader 使用 ILT(导入查找表)将 EXE 使用的函数与其在 DLL 中的地址关联起来。然而,一旦建立这种关联,DLL 中的地址就会写入 EXE 中的 IAT(导入地址表)。 EXE加载后,它不再需要ILT,当它调用DLL中的函数时,它指向IAT。

@snemarch Is mostly right, though I think both him and the documentation are wrong that the ILT and IAT are the same on disk. I've looked through the bytes, they are not the same.

Though, he is right about the definition and purpose of the tables.

The ILT (Import Lookup Table) is used by the Windows Loader to associate the functions used by an EXE with their address in a DLL. However, once this association is made, the address in the DLL gets written to the IAT (Import Address Table) in the EXE. After the EXE is loaded, it doesn't need the ILT anymore, when it calls a function in a DLL it points into the IAT.

“导入表地址”和“导入表地址”有什么区别?和“导入地址表地址”在 PE 的日期目录中?
