GlobのD Phobosに相当するものはありますか？

Question

私はパスパターンを検索するためにglobを使うことができます。これは、例えば：

/usr/share/python3 
/usr/share/python3-plainbox 
/usr/share/python 
/usr/share/python-apt 
/usr/include/python3.5m 
/usr/bin/python3 
/usr/bin/python3m 
/usr/bin/python2.7 
/usr/bin/python 
/usr/bin/python3.5 
/usr/bin/python3.5m 
/usr/bin/python2 
/usr/lib/python3 
/usr/lib/python2.7 
/usr/lib/python3.5 

どのようにglobまたはD内でグロブと等価になるだろう：

import glob 
for entry in glob.glob("/usr/*/python*"): 
    print(entry) 

はこれを印刷しますか？

------私はDでグロブを行うに小さなDモジュールを書いた

Answer 1

上記の答えは100％GlobとWindowsおよびLinuxと同じです。そこで私はGlobを正しい方法で実行する小さなDモジュールを作った。うまくいけば、人々はそれが便利：

https://github.com/workhorsy/d-glob

import std.stdio : stdout; 
import glob : glob; 

foreach (entry ; glob("/usr/*/python*")) { 
    stdout.writefln("%s", entry); 
} 

Answer 2

はたぶん、あなたはstd.file.dirEntries()を探しています。ここで

は、ドキュメントからの例です：

// Iterate over all D source files in current directory and all its 
// subdirectories 
auto dFiles = dirEntries("","*.{d,di}",SpanMode.depth); 
foreach(d; dFiles) 
    writeln(d.name); 

Answer 3

あなただけのPosixシステム上で動作している場合、あなたは直接glob.hを呼び出すことができます。以下は、Posix APIとのインターフェースがいかに簡単かを示す簡単な例です：

void main() 
{ 
    import std.stdio; 
    import glob : glob; 
    foreach(entry; glob("/usr/*/python*")) 
     writeln(entry); 
} 

これをコンパイルすることができます。 rdmd main.d（rdmdは単純な依存関係管理を行っています）またはdmd main.d glob.dであり、私のマシン上にあなたと同じ出力が得られます。

glob.dはdstepで生成され、便利なDスタイルのラッパー（第1の関数）で拡張されています。これは完全ではないことに注意してください。より良い方法は、配列全体を割り当てる代わりに範囲APIを公開することです。

Answer 4

基本的に、この複雑なものはすべてヘッダーやCなどで行う必要はありません。これは、事を行う必要があります：

auto dirIter = dirEntries("/usr", "*/python*", SpanMode.shallow); 
foreach(dirFile; dirIter) { 
    // Process the result as needed
