<h2><a name="introduction"></a>Introduction</h2>
<p>LuaFileSystem is a <a href="http://www.lua.org">Lua</a> library
developed to complement the set of functions related to file
systems offered by the standard Lua distribution.</p>
<p>LuaFileSystem offers a portable way to access
the underlying directory structure and file attributes.</p>
<h2><a name="installation"></a>Installation</h2>
<p>LuaFileSystem follows the
<a href="http://www.keplerproject.org/compat/">package model</a>
for Lua 5.1, therefore it should be "installed". Refer to
<a href="http://www.keplerproject.org/compat/manual.html#configuration">
Compat-5.1 configuration</a> section about how to install the compiled
binary properly.
The compiled binary should be copied to a directory in your
<code>LUA_CPATH</code>.</p>
<p>Windows users can use the binary version of LuaFileSystem
(<code>lfs.dll</code>) available at
<a href="http://luaforge.net/projects/luafilesystem/files">LuaForge</a>.</p>
<h2><a name="reference"></a>Reference</h2>
<p>
LuaFileSystem offers the following functions:
</p>
<dl class="reference">
<dt><a name="attributes"></a><strong><code>lfs.attributes (filepath [, aname])</code></strong></dt>
<dd>Returns a table with the file attributes corresponding to
<code>filepath</code> (or <code>nil</code> followed by an error message
in case of error).
If the second optional argument is given, then only the value of the
named attribute is returned (this use is equivalent to
<code>lfs.attributes(filepath).aname</code>, but the table is not created
and only one attribute is retrieved from the O.S.).
The attributes are described as follows;
attribute <code>mode</code> is a string, all the others are numbers:
<dl>
<dt><strong><code>dev</code></strong></dt>
<dd>on Unix systems, this represents the device that the inode resides on. On Windows systems,
represents the drive number of the disk containing the file</dd>
<dt><strong><code>ino</code></strong></dt>
<dd>on Unix systems, this represents the inode number. On Windows systems this has no meaning</dd>
<dt><strong><code>mode</code></strong></dt>
<dd>string representing the associated protection mode (the values could be
<code>file</code>, <code>directory</code>, <code>link</code>, <code>socket</code>,
<code>named pipe</code>, <code>char device</code>, <code>block device</code> or
<code>other</code>)</dd>
<dt><strong><code>nlink</code></strong></dt>
<dd>number of hard links to the file</dd>
<dt><strong><code>uid</code></strong></dt>
<dd>user-id of owner (Unix only, always 0 on Windows)</dd>
<dt><strong><code>gid</code></strong></dt>
<dd>group-id of owner (Unix only, always 0 on Windows)</dd>
<dt><strong><code>rdev</code></strong></dt>
<dd>on Unix systems, represents the device type, for special file inodes.
On Windows systems represents the same as <code>dev</code></dd>
<dt><strong><code>access</code></strong></dt>
<dd>time of last access</dd>
<dt><strong><code>modification</code></strong></dt>
<dd>time of last data modification</dd>
<dt><strong><code>change</code></strong></dt>
<dd>time of last file status change</dd>
<dt><strong><code>size</code></strong></dt>
<dd>file size, in bytes</dd>
<dt><strong><code>blocks</code></strong></dt>
<dd>block allocated for file; (Unix only)</dd>
<dt><strong><code>blksize</code></strong></dt>
<dd>optimal file system I/O blocksize; (Unix only)</dd>
</dl>
</dd>
<dt><a name="chdir"></a><strong><code>lfs.chdir (path)</code></strong></dt>
<dd>Changes the current working directory to the given
<code>path</code>.<br />
Returns <code>true</code> in case of success or <code>nil</code> plus an
error string.</dd>
<dt><a name="getcwd"></a><strong><code>lfs.currentdir ()</code></strong></dt>
<dd>Returns a string with the current working directory or <code>nil</code>
plus an error string.</dd>
<dt><a name="dir"></a><strong><code>lfs.dir (path)</code></strong></dt>
<dd>
Lua iterator over the entries of a given directory.
Each time the iterator is called it returns a string with an entry of the
directory; <code>nil</code> is returned when there is no more entries.
Raises an error if <code>path</code> is not a directory.
</dd>
<dt><a name="lock"></a><strong><code>lfs.lock (filehandle, mode[, start[, length]])</code></strong></dt>
<dd>Locks a file or a part of it. This function works on <em>open files</em>; the
file handle should be specified as the first argument.
The string <code>mode</code> could be either
<code>r</code> (for a read/shared lock) or <code>w</code> (for a
write/exclusive lock). The optional arguments <code>start</code>
and <code>length</code> can be used to specify a starting point and
its length; both should be numbers.<br />
Returns <code>true</code> if the operation was successful; in
case of error, it returns <code>nil</code> plus an error string.
</dd>
<dt><a name="mkdir"></a><strong><code>lfs.mkdir (dirname)</code></strong></dt>
<dd>Creates a new directory. The argument is the name of the new
directory.<br />
Returns <code>true</code> if the operation was successful;
in case of error, it returns <code>nil</code> plus an error string.
</dd>
<dt><a name="rmdir"></a><strong><code>lfs.rmdir (dirname)</code></strong></dt>
<dd>Removes an existing directory. The argument is the name of the directory.<br />
Returns <code>true</code> if the operation was successful;
in case of error, it returns <code>nil</code> plus an error string.</dd>
<dt><a name="touch"></a><strong><code>lfs.touch (filepath [, atime [, mtime]])</code></strong></dt>
<dd>Set access and modification times of a file. This function is
a bind to <code>utime</code> function. The first argument is the
filename, the second argument (<code>atime</code>) is the access time,
and the third argument (<code>mtime</code>) is the modification time.
Both times are provided in seconds (which should be generated with
Lua standard function <code>os.date</code>).
If the modification time is omitted, the access time provided is used;
if both times are omitted, the current time is used.<br />
Returns <code>true</code> if the operation was successful;
in case of error, it returns <code>nil</code> plus an error string.
</dd>
<dt><a name="unlock"></a><strong><code>lfs.unlock (filehandle[, start[, length]])</code></strong></dt>
<dd>Unlocks a file or a part of it. This function works on
<em>open files</em>; the file handle should be specified as the first
argument. The optional arguments <code>start</code> and
<code>length</code> can be used to specify a starting point and its
length; both should be numbers.<br />
Returns <code>true</code> if the operation was successful;
in case of error, it returns <code>nil</code> plus an error string.

<h2>Introduction</h2>
<p>
LuaFileSystem is a <a href="http://www.lua.org">Lua</a> library
developed to complement the set of functions related to file systems offered
by the standard Lua distribution.
<p>
LuaFileSystem is free software and uses the same
<a href="license.html">license</a>
as Lua 5.0.
</p>
<a name="reference"></a>
<h2>Reference</h2>
<p>
LuaFileSystem offers the following functions:
<ul>
<a name="chdir"></a>
<li> <b><tt>luafilesystem.chdir (path)</tt></b> <br>
Changes the current
working directory to the given <tt>path</tt>.
<a name="getcwd"></a>
<li> <b><tt>luafilesystem.currentdir ()</tt></b> <br>
Returns the current
working directory or <code>nil</code> plus an error string.
<a name="dir"></a>
<li> <b><tt>luafilesystem.dir (path)</tt></b> <br>
Lua iterator over the entries
of a given directory.
<a name="lock"></a>
<li> <b><tt>luafilesystem.lock (filehandle, mode[, start[, length]])</tt></b> <br>
Locks a file or a part of it.
This function works on <em>open files</em>;
the file handle should be specified as the first argument.
The string <code>mode</code> could be either <code>r</code> (for a
read/shared lock) or <code>w</code> (for a write/exclusive lock).
The optional arguments <code>start</code> and <code>length</code> can be
used to specify a starting point and its length;
both should be numbers.
This function returns a boolean indicating if the operation was successful;
in case of error, it returns <code>false</code> plus a string describing the
error.
<a name="mkdir"></a>
<li> <b><tt>luafilesystem.mkdir (dirname)</tt></b> <br>
Creates a new directory.
The argument is the name of the new directory.
<a name="unlock"></a>
<li> <b><tt>luafilesystem.unlock (filehandle[, start[, length]])</tt></b> <br>
Unlocks a file or a part of it.
This function works on <em>open files</em>;
the file handle should be specified as the first argument.
The optional arguments <code>start</code> and <code>length</code> can be
used to specify a starting point and its length;
both should be numbers.
This function returns a boolean indicating if the operation was successful;
in case of error, it returns <code>false</code> plus a string describing the
error.
