blocks|key|2042276|text|啊哈。大约15年前，我不得不在ANSI中实现类似的东西。我想从ANSI+opendir/readdir例程开始吧。Globs并不完全是RegExs，所以你必须实现你自己的过滤。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2042277|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Ehw. I had to implement something like this in ANSI C about 15 years ago. Start with the ANSI opendir/readdir routines, I guess. Globs aren't exactly RegExs, so you will have to implement your own filtering.

there was talk about having it in Boost::filesystem but it was dropped in favor of using the boost::regex.

For win32 specific (MFC) you can use the <a href="http://msdn.microsoft.com/en-us/library/f33e1618(VS.80).aspx" rel="nofollow noreferrer">CFileFind</a> class

blocks|key|2042541|text|现在可能有更好的方法，但上次我不得不处理这个问题时，我最终将Henry+Spencer's+regex+library静态链接到我的程序中(他的库是BSD许可的)，然后我创建了一个包装类，将用户的glob表达式转换为正则表达式，以提供给正则表达式。如果愿意，您可以查看/抓取包装类here。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|2042542|一旦这些部分就位，最后要做的就是实际读取目录，并将每个条目名称传递给匹配函数，以查看它是否与表达式匹配。匹配的文件名，添加到向量中；不匹配的文件名则丢弃。使用DOS的_findfirst()和_findnext()函数读取目录是相当简单的，但是如果你想要一个更好的C%2B%2B接口，我有一个portable+wrapper类来做这件事。|2042543|entityMap|0|LINK|mutability|MUTABLE|url|http://arglist.com/regex/|1|https://public.msli.com/lcs/muscle/html/classmuscle_1_1StringMatcher.html|2|https://public.msli.com/lcs/muscle/html/classmuscle_1_1Directory.html^0|U|T|0|3W|4|1|0|3Y|G|2|0^^$0|@$1|2|3|4|5|6|7|R|8|@]|9|@$A|S|B|T|1|U]|$A|V|B|W|1|X]]|C|$]]|$1|D|3|E|5|6|7|Y|8|@]|9|@$A|Z|B|10|1|11]]|C|$]]|$1|F|3|-4|5|6|7|12|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]|N|$5|I|J|K|C|$L|O]]|P|$5|I|J|K|C|$L|Q]]]]

There may be a better way now, but last time I had to deal with this problem I ended up including <a href="http://arglist.com/regex/" rel="nofollow noreferrer">Henry Spencer's regex library</a> statically linked into my program (his library is BSD licensed), and then I made a wrapper class that converted the user's glob-expressions into regular expressions to feed to the regex code. You can view/grab the wrapper class <a href="https://public.msli.com/lcs/muscle/html/classmuscle_1_1StringMatcher.html" rel="nofollow noreferrer">here</a> if you like.

Once you have those parts in place, the final thing to do is actually read the directory, and pass each entry name into the matching function to see if it matches the expression or not. The filenames that match, you add to your vector; the ones that don't you discard. Reading the directory is fairly straightforward to do using the DOS _findfirst() and _findnext() functions, but if you want a nicer C++ interface I have a <a href="https://public.msli.com/lcs/muscle/html/classmuscle_1_1Directory.html" rel="nofollow noreferrer">portable wrapper</a> class for that also...

This is very Windows-specific. I don't know how you'd write this to be cross-platform. But I've used this in Windows programs and it works well for me.

<pre><code>// Change to the specified working directory
string path;
cout &lt;&lt; "Enter the path to report: ";
cin &gt;&gt; path;
_chdir(path.c_str());

// Get the file description
string desc;
cout &lt;&lt; "Enter the file description: ";
cin &gt;&gt; desc;

// List the files in the directory
intptr_t file;
_finddata_t filedata;
file = _findfirst(desc.c_str(),&amp;filedata);
if (file != -1)
{
 do
 {
 cout &lt;&lt; filedata.name &lt;&lt; endl;
 // Or put the file name in a vector here
 } while (_findnext(file,&amp;filedata) == 0);
}
else
{
 cout &lt;&lt; "No described files found" &lt;&lt; endl;
}
_findclose(file);
</code></pre>

Is there a smooth way to glob in C or C++ in Windows?

E.g., myprogram.exe *.txt sends my program an ARGV list that has...ARGV[1]=<code>*.txt</code> in it.

I would like to be able to have a function (let's call it readglob) that takes a string and returns a vector of strings, each containing a filename.

This way, if I have files <code>a.txt b.txt c.txt</code> in my directory and readglob gets an argument <code>*.txt</code>, it returns the above filelist.

<pre><code>//Prototype of this hypothetical function.
vector&lt;string&gt; readglob(string);
</code></pre>

Does such exist?

Globbing in C++/C, on Windows

在Windows或C++中有没有一种流畅的方法来实现glob？例如，myprogram.exe *.txt向我的程序发送了一个has...ARGV1=*.txt的ARGV列表。我希望能够有一个函数(让我们叫它readglob)，它接受一个字符串并返回一个字符串向量，每个字符串都包含一个文件名。这样，如果我的目录中有文件...
