用于创建“漂亮”目录树的ASCII库？

是否有一些* nix工具或perl / php库，可让您轻松创建类似于以下内容的目录树可视化效果？

www
|-- private
|    |-- app 
|    |    |-- php
|    |    |    |-- classes
|    |    |    +-- scripts
|    |    |-- settings
|    |    +-- sql
|    +-- lib
|         +-- ZendFramework-HEAD
+-- public
    |-- css
    |-- images
    +-- scripts

Unix Tree / Linux Tree中的示例如何？

ls -R | grep ":$" | sed -e 's/:$//' -e 's/[^-][^\/]*\//--/g' -e 's/^/   /' -e 's/-/|/'  

那个oneliner很酷，我建议使用tree util。

bash-3.2$ mkdir -p this/is/some/nested/example
bash-3.2$ mkdir -p this/is/another/super/nested/example
bash-3.2$ mkdir -p this/is/yet/another/example
bash-3.2$ mkdir -p this/is/some/nested/other/example
bash-3.2$ tree this
this
`-- is
    |-- another
    |   `-- super
    |       `-- nested
    |           `-- example
    |-- some
    |   `-- nested
    |       |-- example
    |       `-- other
    |           `-- example
    `-- yet
        `-- another
            `-- example

13 directories, 0 files

我意识到这个问题早在很久以前就得到了回答，但是我才发现这个叫做tree的程序也很酷。

看RecursiveTreeIterator课

允许在RecursiveIterator上进行迭代以生成ASCII图形树。

$treeIterator = new RecursiveTreeIterator(
    new RecursiveDirectoryIterator('/path/to/dir'),
    RecursiveTreeIterator::SELF_FIRST);

foreach($treeIterator as $val) echo $val, PHP_EOL;

输出将是这样的（在我的机器上是c：\ php）：

|-c:\php5\cfg
|-c:\php5\data
| |-c:\php5\data\Base
| | \-c:\php5\data\Base\design
| |   |-c:\php5\data\Base\design\class_diagram.png
| |   \-c:\php5\data\Base\design\design.txt
| |-c:\php5\data\ConsoleTools
| | \-c:\php5\data\ConsoleTools\design
| |   |-c:\php5\data\ConsoleTools\design\class_diagram.png
| |   |-c:\php5\data\ConsoleTools\design\console.png
| |   |-c:\php5\data\ConsoleTools\design\console.xml
…

与--tree的exa表现出色：

exa --tree ~/tmp/public/

<dir>
├── aboutme
│  └── index.html
├── atrecurse
│  └── index.html
├── base.css
├── html5
│  ├── cat-and-mouse
│  └── frantic
│     ├── css
│     │  └── main.css

本身不是一个库，但是这个小工具很方便在不离开浏览器的情况下生成快速树图：https : //tree.nathanfriend.io/

免责声明：我是作者:)。

很酷的Python脚本可以做到这一点：http : //code.activestate.com/recipes/217212/

[php]调整树符号，取自https://gist.github.com/hakre/3599532

<?php
$path = './targetdir';
$unicodeTreePrefix = function(RecursiveTreeIterator $tree){
  $prefixParts = [
      RecursiveTreeIterator::PREFIX_LEFT         => ' ',
      RecursiveTreeIterator::PREFIX_MID_HAS_NEXT => '+ ',
      RecursiveTreeIterator::PREFIX_END_HAS_NEXT => '├ ',
      RecursiveTreeIterator::PREFIX_END_LAST     => '└ '
    ];
  foreach ($prefixParts as $part => $string) {
      $tree->setPrefixPart($part, $string);
  }
};
$dir  = new RecursiveDirectoryIterator($path, RecursiveDirectoryIterator::KEY_AS_FILENAME | RecursiveDirectoryIterator::SKIP_DOTS);
$tree = new RecursiveTreeIterator($dir);
$unicodeTreePrefix($tree);
echo "<br><br>";
echo "[$path]<br>";
foreach ($tree as $filename => $line) {
  echo $tree->getPrefix(), $filename, "<br>";
}

输出示例

近年来，这已经发生了很多变化。软件包管理器中的linux版本更加干净和彩色：

Debian / Ubuntu：

sudo apt install tree

CentOS / RHEL / OpenSUSE：

sudo yum install tree

如果您的current_directory结构有一个庞大的子目录，并且只想显示该结构包含的样本，则可以执行以下操作：

tree -P *my_own_pattern_to_find* current_directory
