Tree and files
|
|
==============
|
|
|
|
To organize folders, git uses trees. In gitlib, those trees are
|
|
represented via *Tree* object.
|
|
|
|
To get the root tree associated to a commit, use the *getTree* method on
|
|
the commit object:
|
|
|
|
```php
|
|
$tree = $commit->getTree();
|
|
```
|
|
|
|
This tree is the entry point of all of your files.
|
|
|
|
The main method for a tree is the *getEntries* method. This method will
|
|
return an array, indexed by name. Each of those elements will be the
|
|
entry mode and the entry object.
|
|
|
|
Let's understand how it works with a concrete example:
|
|
|
|
```php
|
|
function displayTree(Tree $tree, $indent = 0)
|
|
{
|
|
$indent = str_repeat(' ', $indent);
|
|
foreach ($tree->getEntries() as $name => $data) {
|
|
list($mode, $entry) = $data;
|
|
if ($entry instanceof Tree) {
|
|
echo $indent.$name.'/'.PHP_EOL;
|
|
displayTree($tree, $indent + 1);
|
|
} else {
|
|
echo $indent.$name.PHP_EOL;
|
|
}
|
|
}
|
|
}
|
|
|
|
displayTree($commit->getTree());
|
|
```
|
|
|
|
This method will recursively display all entries of a tree.
|
|
|
|
Resolve a path
|
|
--------------
|
|
|
|
To access directly a sub-file, the easier is probably to use the
|
|
*resolvePath* method.
|
|
|
|
An example:
|
|
|
|
```php
|
|
$source = $tree->resolvePath('src/Gitonomy/Git');
|
|
|
|
$source instanceof Tree;
|
|
```
