<h1><a name="001000000000">Portable path handling</a></h1>
<p>
Portable path handling (across both unix-like and
mswindows operating systems) requires some care. A
modern operating system uses the concept of a single
root to the filesystem, but mswindows has multiple
filesystems with no common root, so code must be
aware of this. There is also the more minor issue that
windows often uses a backslash as a separator between
the components of a path and unix-like systems always use
forward slash. <br /> On windows there is also the
issue that two styles of path are used, most commonly
with a drive letter and a path on that drive (eg.
'C:\directory\file') but also UNC paths
(eg. '//host/share/directory/file') so path handling
functions must deal with both formats.
</p>
<p>
GNUstep has three path handling modes, 'gnustep',
'unix', and 'windows'. The mode defaults to 'gnustep'
but may be set using the
GSPathHandling()
function. <br /> You should probably stick to using
the default 'gnustep' mode in which the path handling
methods cope with both 'unix' and 'windows' style paths
in portable and tolerant manner: <br /> Paths are read in
literally so they can be in the native format
provided by the operating system or in a non-native
format. See
[NSFileManager -stringWithFileSystemRepresentation:length:]
. <br /> Paths are written out using the native format of the system the application is running on (eg on windows slashes are converted to backslashes). See [NSFileManager -fileSystemRepresentationWithPath:]
. <br /> The path handling methods accept either a forward or backward slash as a path separator when parsing any path. <br /> Unless operating in 'unix' mode, a leading letter followed by a colon is considered the start of a windows style path (the drive specifier), and a path beginning with something of the form '//host/share/' is considered the start of a UNC style path. <br /> The path handling methods add forward slashes when building new paths internally or when standardising paths, so those path strings provide a portable representation (as <strong>long</strong> as they are relative paths, not including system specific roots). <br /> An important case to note is that on windows a path which looks at first glance like an absolute path may actually be a relative one. <br /> 'C:file' is a relative path because it specifies a file on the C drive but does not say what directory it is in. <br /> Similarly, '/dir/file' is a relative path because it specifies the full location fo a file on a drive, but does not specify which drive it is on.
</p>
<p>
As a consequence of this path handling, you are able to work
completely portably using relative paths (adding
components, extensions and relative paths to a pth,
or removing components, extensions and relative paths from a
path etc), and when you save paths as strings in files
which may be transferred to another platform, you should
save a relative path. <br /> When you need to know
absolute paths of various points in the filesystem,
you can use various path utility functions to obtain those
absolute paths. For instance, instead of saving an
absolute path to a file, you might want to save a path
relative to a user's home directory. You could do that
by calling
<a rel="gsdoc" href="Functions.html#function$NSHomeDirectory">
NSHomeDirectory()
</a>
to get the home directory, and only saving the part of the
full path after that prefix.

<code>NSString</code> objects represent an immutable
string of Unicode 3.0 characters. These may be
accessed individually as type
<code><strong>unichar</strong></code>, an
<strong>unsigned</strong> <strong>short</strong>.
<br /> The
<a rel="gsdoc" href="#class$NSMutableString">NSMutableString</a>
subclass represents a modifiable string. Both are implemented as part of a class cluster and the instances you receive may actually be of unspecified concrete subclasses. </p>
<p>
</p>
<p>
A constant <code>NSString</code> can be created using
the following syntax: <code>@"..."</code>, where the
contents of the quotes are the string, using
only ASCII characters.
</p>
<p>
</p>
<p>
A variable string can be created using a C printf-like
<em>format</em>, as in
<code>
[NSString stringWithFormat: @"Total is %f",
t]
</code>
.
</p>
<p>
</p>
<p>
To create a concrete subclass of <code>NSString</code>
, you must have your class inherit from
<code>NSString</code> and override at least the
two primitive methods -
<a rel="gsdoc" href="#method$NSString-length">
-length
</a>
and
<a rel="gsdoc" href="#method$NSString-characterAtIndex$">
-characterAtIndex:
</a>
</p>
<p>
</p>
<p>
In general the rule is that your subclass must
override any initialiser that you want to use
with it. The GNUstep implementation relaxes that to
say that, you may override only the
<em>designated initialiser</em> and the other
initialisation methods should work.
</p>
<p>
</p>
<p>
Where an NSString instance method returns an
NSString object, the class of the actual object
returned may be any subclass of NSString. The
actual value returned may be a new autoreleased
object, an autoreleased copy of the receiver, or
the receiver itsself. While the abstract base class
implementations of methods (other than
initialisers) will avoid returning mutable
strings by returning an autoreleased copy of a
mutable receiver, concrete subclasses may behave
differently, so code should not rely upon
the mutability of returned strings nor upon their
lifetime being greater than that of the receiver
which returned them.

In MacOS-X class clusters do not have designated
initialisers, and there is a general rule
that <a rel="gsdoc" href="#method$NSString-init">-init</a>
is
treated as the designated initialiser of the
class cluster, but that other intitialisers may not
work as expected and would need to be individually
overridden in any subclass.
</p>
<p>
</p>
<p>
GNUstep tries to make it easier to subclass a
class cluster, by making class clusters follow the
same convention as normal classes, so the designated
initialiser is the <em>richest</em>
initialiser. This means that all other
initialisers call the documented designated
initialiser (which calls
<a rel="gsdoc" href="#method$NSString-init">
-init
</a>
only for MacOS-X compatibility), and anyone writing
a subclass only needs to override that one initialiser
in order to have all the other ones work.
</p>
<p>
</p>
<p>
For MacOS-X compatibility, you may also need to
override various other initialisers. Exactly
which ones, you will need to determine by trial on
a MacOS-X system... and may vary between releases of
MacOS-X. So to be safe, on MacOS-X you probably
need to re-implement <em>all</em> the class cluster
initialisers you might use in conjunction
with your subclass.
</p>
<p>
</p>
<p>
NB. The GNUstep designated initialiser for the
NSString class cluster has changed to
<a rel="gsdoc" href="#method$NSString-initWithBytesNoCopy$length$encoding$freeWhenDone$">-initWithBytesNoCopy:length:encoding:freeWhenDone:</a>
from <a rel="gsdoc" href="#method$NSString-initWithCharactersNoCopy$length$freeWhenDone$">-initWithCharactersNoCopy:length:freeWhenDone:</a>
and older code subclassing NSString will need to be updated.

<p>
Attempts to interpret the receiver as a
<em>property list</em> and returns the result. If
the receiver does not contain a string representation
of a <em>property list</em> then the method returns
<code>nil</code>.
</p>
<p>
</p>
<p>
Containers (arrays and dictionaries) are
decoded as <em>mutable</em> objects.
</p>
<p>
</p>
<p>
There are three readable <em>property list</em>
storage formats - The binary format used by
<a rel="gsdoc" href="NSSerialization.html#class$NSSerializer">NSSerializer</a>
does not concern us here, but there are two 'human
readable' formats, the <em>traditional</em>
OpenStep format (which is extended in GNUstep)
and the <em>XML</em> format.
</p>
<p>
</p>
<p>
The
<a rel="gsdoc" href="NSArray.html#method$NSArray-descriptionWithLocale$indent$">[NSArray -descriptionWithLocale:indent:]</a>
and <a rel="gsdoc" href="NSDictionary.html#method$NSDictionary-descriptionWithLocale$indent$">[NSDictionary -descriptionWithLocale:indent:]</a>
methods both generate strings containing traditional style <em>property lists</em>, but <a rel="gsdoc" href="NSArray.html#method$NSArray-writeToFile$atomically$">[NSArray -writeToFile:atomically:]</a>
and <a rel="gsdoc" href="NSDictionary.html#method$NSDictionary-writeToFile$atomically$">[NSDictionary -writeToFile:atomically:]</a>
generate either traditional or XML style <em>property lists</em> depending on the value of the GSMacOSXCompatible and NSWriteOldStylePropertyLists user defaults. <br /> If GSMacOSXCompatible is <code>YES</code> then XML <em>property lists</em> are written unless NSWriteOldStylePropertyLists is also <code>YES</code>. <br /> By default GNUstep writes old style data and always supports reading of either style.
</p>
<p>
</p>
<p>
The traditional format is more compact and more
easily readable by people, but (without the
GNUstep extensions) cannot represent date and
number objects (except as strings). The XML
format is more verbose and less readable, but
can be fed into modern XML tools and thus used to
pass data to non-OpenStep applications more
readily.
</p>
<p>
</p>
<p>
The traditional format is strictly ascii encoded,
with any unicode characters represented by escape
sequences. The XML format is encoded as UTF8
data.
</p>
<p>
</p>
<p>
Both the traditional format and the XML format
permit comments to be placed in
<em>property list</em> documents. In traditional
format the comment notations used in Objective-C
programming are supported, while in XML
format, the standard SGML comment sequences are
used.
</p>
<p>
</p>
<p>
See the documentation for
<a rel="gsdoc" href="NSPropertyList.html#class$NSPropertyListSerialization">NSPropertyListSerialization</a>
for more information on what a property list is. </p>
<p>
</p>
<p>
If the string cannot be parsed as a normal
property list format, this method also tries
to parse it as 'strings file' format (see the
<a rel="gsdoc" href="#method$NSString-propertyListFromStringsFileFormat">-propertyListFromStringsFileFormat</a>
method).

Reads a <em>property list</em> (see -propertyList)
from a simplified file format. This format is a
traditional style property list file
containing a single dictionary, but with the
leading '{' and trailing '}' characters omitted.
</p>
<p>
</p>
<p>
That is to say, the file contains only semicolon
separated key/value pairs (and optionally
comments). As a convenience, it is possible to
omit the equals sign and the value, so an entry
consists of a key string followed by a
semicolon. In this case, the value for that
key is assumed to be an empty string.

so a copy of the unmodified receiver is returned. <br />
An empty string may be used as an extension... in which
case the extension separator is appended. <br /> This
behavior mirrors that of the

@"Mail" with @"app" produces @"Mail.app"

@"file" with @"" produces @"file."
@"/" with @"app" produces @"/" (no file name to append to)
@"" with @"app" produces @"" (no file name to append to)

NB. Do not use this method to modify strings other than
filesystem paths as the behavior in such cases

</p>
<p>
The NXConstantString class is used to hold constant
8-bit character string objects produced by the
compiler where it sees @"..." in the source. The
compiler generates the instances of this class -
which has three instance variables -
</p>
<p>
<ul>
<li>
a pointer to the class (this is the sole ivar of
NSObject)
</li>
<li>
a pointer to the 8-bit data
</li>
<li>
the length of the string
</li>
</ul>
</p>
<p>
In older versions of the compiler, the isa variable is
always set to the NXConstantString class. In newer
versions a compiler option was added for GNUstep,
to permit the isa variable to be set to another class,
and GNUstep uses this to avoid conflicts with the
default implementation of NXConstantString in the
ObjC runtime library (the preprocessor is used to
change all occurrences of NXConstantString in the
source code to NSConstantString).
</p>
<p>
</p>
<p>
Since GNUstep will generally use the GNUstep
extension to the compiler, you should never refer
to the constant string class by name, but should use the
<a rel="gsdoc" href="#method$NSString+constantStringClass">[NSString +constantStringClass]</a>
method to get the actual class being used for constant strings.
</p>
<p>
What follows is a dummy declaration of the class to keep
the compiler happy.
