Filenames in Unix.
defaults
-
defaultTempDirectoryName
-
return the default temp directory as a filename.
By default, this is '/tmp', but can be overriden by one of
the shell variables: ('STX_TMPDIR' 'ST_TMPDIR' 'TMPDIR' 'TEMPDIR' 'TEMP' 'TMP')
usage example(s):
Filename defaultTempDirectoryName
Filename defaultTempDirectoryName exists
Filename defaultTempDirectoryName isWritable

misc
-
nameWithSpecialExpansions: aString
-
return the nameString, expanding any OS specific macros.
Here, a ~/ or ~user/ prefix is expanded to the users home dir (as in csh)
usage example(s):
self nameWithSpecialExpansions:'/usr/lib'
self nameWithSpecialExpansions:'$JAVA_HOME/bin'
self nameWithSpecialExpansions:'${JAVA_HOME}/bin'
self nameWithSpecialExpansions:'${JAVA_HOME}-tttttt'
self nameWithSpecialExpansions:'$(JAVA_HOME)/bin'
self nameWithSpecialExpansions:'$(JAVA_HOME)bin'
self nameWithSpecialExpansions:'~/work'
self nameWithSpecialExpansions:'~stefan/test'

queries
-
isBadCharacter: aCharacter
-
return true, if aCharacter is unallowed in a filename.
-
isCaseSensitive
-
return true, if filenames are case sensitive.
This is not really correct, as the sensitivity may depend on
the paricular mounted file system (NFS, for example)
-
nullFilename
-
Return /dev/null
usage example(s):
-
parentDirectoryName
-
return the name used for the parent directory.
This is '..' for unix and dos-like systems.
(there may be more in the future.
-
separator
-
return the file/directory separator.
usage example(s):
Filename concreteClass separator
|
-
separatorString
-
return the file/directory separator as a string.
usage example(s):
file queries
-
fileType
-
this returns a string describing the type of contents of the file.
This is done using the unix 'file' command,
(which usually is configurable by /etc/magic).
Warning:
Since the returned string differs among systems (and language settings),
it is only useful for user-information;
NOT as a tag to be used by a program.
For this, use mimeType or mimeTypeOfContents.
usage example(s):
ones are checked first, using the general fileType implementation.

usage example(s):
'Makefile' asFilename fileType
'.' asFilename fileType
'/dev/null' asFilename fileType
'smalltalk.rc' asFilename fileType
'bitmaps/SBrowser.xbm' asFilename fileType
'../../libtool/bitmaps/SBrowser.xbm' asFilename fileType
'./stx' asFilename fileType

queries
-
isExplicitRelative
-
return true, if this name is an explicit relative name
(i.e. starts with './' or '../', to avoid path-prepending)
-
isHidden
-
return true, if the receiver represents a hidden file.
On UNIX, a name starting with a period is considered hidden.
-
isImplicit
-
return true, if the receiver represents builtin names such as '.' or '..'.
On UNIX, the current and parent dir names are considered implicit.
special accessing
-
osName
-
redefined from superclass, because we do not distinguish file and directory names
-
osNameForFile
-
internal - return the OS's name for the receiver to
access it as a file.
