The proper value to use for a wild pathname component.
A pathname that is wild in its directory spec (can match any directory).
A pathname that is wild in its file spec (can match any file).
A pathname that has wild inferiors (can match any number of subdirectories).
The proper value to use for a wild inferiors pathname component.
A pathname that is wild in both its file and its directory.
Returns the pathname if it is an absolute pathname.
The pathname is coerced using PATHNAME*
See PATHNAME*
Removes superfluous components from the directory spec.
Specifically, if the encountered part is UNSPECIFIC or the
string ".", it is omitted. If the part is :BACK, the
preceding component is omitted if possible. If not possible,
an equivalent amount of :UP specs are inserted instead.
If UP-AS-BACK is T then :UP is treated the same as :BACK,
otherwise :UP elements are not removed from the spec.
If RESOLVE-HOME is T then the :HOME part, if present, is replaced by the actual directory components of USER-HOMEDIR-PATHNAME
Returns a plist containing all the components making up the given pathname.
The plist contains the following keys:
:namestring
:truename
:host
:device
:name
:type
:version
:directory
If the pathname has no truename, its value in the plist is NIL.
Returns the name of the topmost directory in the pathname, if any.
The pathname is coerced using TO-DIRECTORY
See TO-DIRECTORY
Returns the pathname if it denotes a directory (not a file).
The pathname is coerced using PATHNAME*
See PATHNAME*
Returns the namestring separator between directories as a string.
Produce a namestring according to DOS rules.
- If the pathname is absolute:
- If the first directory component is :HOME, the
(USER-HOMEDIR-PATHNAME) is emitted.
- If the pathname has a device, the device name followed by a colon
and a backslash is emitted.
- Otherwise a backslash is emitted.
- For every directory component, the component followed by a backslash
is emitted. In the case of :UP or :BACK, they are emitted as two
dots.
- The pathname name, if any, is emitted
- The pathname type, if any, is emitted following a dot.
If the pathname contains illegal characters or components, a
continuable error is signalled unless :JUNK-ALLOWED T is passed. If
the error is continued or :JUNK-ALLOWED T is passed, the component or
character is ignored. The following characters are illegal:
\ / < > : " | ? * Nul
Any component that isn’t one of the following is considered illegal:
:BACK :UP :UNSPECIFIC :HOME NIL string
As the representation is implementation-internal and DOS has no syntax
for wild pathname patterns.
If STREAM is NIL, the namestring is printed to a string and returned.
See NATIVE-NAMESTRING
Moves the topmost pathname component one or more levels downwards.
Specifically, if we have a file "foo/bar.jpg", and move it
downwards by "baz", the resulting pathname will be
"foo/baz/bar.jpg". If the pathname is a directory-pathname
then the last directory is moved downwards by one.
See SUBDIRECTORY
Like ENOUGH-NAMESTRING but returns an actual pathname.
The pathname is coerced using PATHNAME*
See PATHNAME*
Returns a pathname to the given file but in the given directory.
This is useful when carrying over a file to another directory. Essentially this constructs a pathname with the name and type of FILE, but the rest of DIR.
Returns the complete file name as it would be used by the OS, if any.
If the pathname is wild in its name or type component, an error is signalled.
Returns the pathname if it denotes a file (not a directory).
The pathname is coerced using PATHNAME*
See PATHNAME*
Returns the actual file type.
This is different from PATHNAME-TYPE in the following manner:
If PATHNAME-TYPE is specific, but contains a dot, only the part
after the last dot is used as it would indicate the actual file-type
on any recent system. If PATHNAME-TYPE is unspecific, the
PATHNAME-NAME is specific, and it contains a dot in any position but
the first, then that last part is used instead. Otherwise NIL is
returned.
If the pathname is wild in its type or name component, an error is signalled.
Forces the pathname into a directory, including its file namestring.
Meaning: #p"a" => #p"a/"
The pathname is first coerced using PATHNAME*
See PATHNAME*
See TO-DIRECTORY
Returns the pathname if it is a logical pathname.
The pathname is coerced using PATHNAME*
See PATHNAME*
Merges the two pathnames together.
This works like CL:MERGE-PATHNAMES, but with the following changes:
- All kinds of unspecific components are treated as NIL
- The pathname-host of the BASE is always used
See UNSPECIFIC-P
Produce a namestring appropriate for the current platform.
This avoids pitfalls with printing namestrings with the default common
lisp functions, as they may contain unsuitable characters, or syntax
not known to other native applications.
If the pathname contains illegal characters or components, a
continuable error is signalled unless :JUNK-ALLOWED T is passed.
If STREAM is NIL, the namestring is printed to a string and returned.
See PARSE-NATIVE-NAMESTRING
See UNIX-NAMESTRING
See DOS-NAMESTRING
Attempts to normalize the directory specification into one as specified by CLHS.
Also cleans the directory spec.
See CLEAN-DIRECTORY-SPEC
Returns a normalised form of the given pathname.
More specifically, the given object is ensured to be a pathname
using CL:PATHNAME, then turned into a new pathname with the
following properties: an unspecific component is turned into
NIL and the directory component is normalised through
NORMALIZE-DIRECTORY-SPEC.
See UNSPECIFIC-P
See NORMALIZE-DIRECTORY-SPEC
Returns the parent of the pathname.
If the pathname is a directory-pathname, it returns a pathname
that points to the parent thereof, if possible. Specifically,
if the directory is relative and empty, :up is inserted. If
it is absolute and empty, the same pathname is returned. If
it is not empty, then the last component of the directory is
removed. If the pathname is a file pathname, this is equivalent
to TO-DIRECTORY.
The pathname is coerced using PATHNAME*.
If you need to preserve the pathname’s file component, consider
using UPWARDS instead.
See PATHNAME*
See TO-DIRECTORY
Parse a namestring according to DOS rules.
Specifically:
- A path starting with a character followed by a colon is an absolute
path.
- Any subsequent slash or backslash is used as a directory separator.
- A path starting with a directory component that starts and ends with
a percentage is denoting a environment-variable-relative pathname
and is parsed by merging the rest of the parsed pathname with the
pathname resulting from parsing the environment variable of the
indicated name. If the variable is empty or does not exist, it is
ignored.
- A directory component that is empty is ignored.
- A directory component that is a single dot is ignored.
- A directory component that is two dots is converted to :BACK.
- If the namestring is a file namestring:
- If the file namestring starts with a dot, the entire file
namestring is used as the pathname’s name, including the dot.
- If the file namestring contains one or more dots not in the
leading position, the part after the last dot is used as the
pathname type, and the rest as the name.
You may also pass :AS :DIRECTORY to force the namestring to be turned
into a directory-pathname even if it does not end in a directory
separator.
If the namestring contains illegal characters or components, a
continuable error is signalled unless :JUNK-ALLOWED T is passed. If
the error is continued or :JUNK-ALLOWED T is passed, the component or
character is ignored. The following characters are illegal:
< > : " | ? * Nul
See PARSE-NATIVE-NAMESTRING
Parse a namestring appropriate for the current platform.
This avoids pitfalls with parsing namestrings with the default common
lisp functions where possible, as they treat certain characters
specially to allow for wild pathnames.
You may also pass :AS :DIRECTORY to force the namestring to be turned
into a directory-pathname even if it does not end in a directory
separator.
If the namestring contains illegal characters or components, a
continuable error is signalled unless :JUNK-ALLOWED T is passed.
See NATIVE-NAMESTRING
See PARSE-UNIX-NAMESTRING
See PARSE-DOS-NAMESTRING
Parse a namestring according to Unix rules.
Specifically:
- A path with a leading slash is an absolute path.
- Any subsequent slash is used as a directory separator.
- A path with a tilde as the first directory component points to the
home directory.
- A directory component that is empty is ignored.
- A directory component that is a single dot is ignored.
- A directory component that is two dots is converted to :BACK.
- If the namestring is a file namestring:
- If the file namestring starts with a dot, the entire file
namestring is used as the pathname’s name, including the dot.
- If the file namestring contains one or more dots not in the
leading position, the part after the last dot is used as the
pathname type, and the rest as the name.
You may also pass :AS :DIRECTORY to force the namestring to be turned
into a directory-pathname even if it does not end in a directory
separator.
If the namestring contains illegal characters or components, a
continuable error is signalled unless :JUNK-ALLOWED T is passed. If
the error is continued or :JUNK-ALLOWED T is passed, the component or
character is ignored. The following characters are illegal:
Nul
See PARSE-NATIVE-NAMESTRING
Ensures that the argument is a pathname.
If a pathname is passed, it is returned verbatim.
If it is anything else, the value is coerced to a pathname using
NORMALIZE-PATHNAME.
See NORMALIZE-PATHNAME
Returns T if the pathname component matches the pathname component pattern.
This properly handles wild fields in the pattern. An unspecific component in the pattern is treated the same as a wild component. On SBCL it also handles pathname pattern components.
Returns T if the two pathnames denote the same file.
Note that this comparison has to access the file system and might
therefore be costly.
First the two pathnames are turned into truenames using TRUENAME
and then compared using PATHNAME=. This should result in a
comparison that returns true in any situation where the two
pathnames really do refer to the same file, but might not look
the same due to symbolic links or similar effects in the file
system.
See CL:TRUENAME
See PATHNAME=
See PATHNAME-MATCHES-P
Returns T if the given pathname matches the wild pathname pattern.
The pathnames must both be absolute, or both relative.
The pathname must not be wild.
This properly handles wild fields and wild inferiors in the pattern.
An unspecific component in the pattern is treated the same as a wild
component. On SBCL it also handles pathname pattern components.
See PATHNAME-COMPONENT-MATCHES-P
See PATHNAME=
Returns T if the two pathnames are the same.
Note that this comparison is purely based on the pathnames itself
and does not check whether the two might resolve to the same file
on the system.
Relative pathnames are turned into absolute ones by merging them
with *default-pathname-defaults* before being compared.
Each component of the pathnames are compared using EQUAL, but
treating parts that are UNSPECIFIC-P as the same, regardless
of the way in which they might be unspecific.
If IGNORE-VERSION is non-NIL (the default), then the version
component of the pathnames is not compared. This is useful, as it
can be different for pathnames that appear to be the same on some
implementations.
See UNSPECIFIC-P
See PATHNAME-EQUAL
See PATHNAME-MATCHES-P
Returns the pathname if it is a physical pathname.
The pathname is coerced using PATHNAME*
See PATHNAME*
Pops the last component(s) off the pathname-directory part.
The pathname is coerced using PATHNAME*.
Note that this will probably not behave as expected for
pathnames containing :back and :up. For the "intuitive"
behaviour to ascend pathnames, see PARENT or UPWARDS.
See PATHNAME*
Returns the pathname if it is a relative pathname.
The pathname is coerced using PATHNAME*
See PATHNAME*
Computes a relative pathname from one place to another.
The pathnames are first turned into absolute ones by
MERGE-PATHNAMES. Then, the common directory components are
eliminated, leftover directory components on the from path
are converted into :up, and finally the remaining components
of the to path are appended, producing the final directory
component. The name, type, and version are taken from the to
pathname.
If the two pathnames differ in device or host, an error is
signalled instead.
The pathnames are coerced using NORMALIZE-PATHNAME after the
merge.
See NORMALIZE-PATHNAME
Returns the pathname if it denotes an absolute root directory.
The pathname is coerced using PATHNAME*
See PATHNAME*
Returns a directory-pathname with the given subdirectories appended.
For example, appending "bar" and "baz" to "foo/" will
result in "foo/bar/baz/".
The PATHNAME is coerced using TO-DIRECTORY. For any of the
subdirs, if it is a pathname, stream, or keyword, it is coerced
to a pathname using TO-DIRECTORY. If it is a string, it is
coerced using TO-DIRECTORY but with a trailing slash appended.
If you need to preserve the pathname’s file component, consider
using DOWNWARDS instead.
See TO-DIRECTORY
Returns true if SUBPATH denotes a path on a lower level than BASE.
A pathname is considered a subpath of a base pathname if all of
the following are true:
- Their hosts match
- Their devices match
- The base’s name is null or their names match
- The base’s type is null or their types match
- The directory component of the subpath denotes a subdirectory
of the directory component of the base.
If the subpath or base are relative pathnames, they are made
absolute by merging them with the root pathname. If the root
pathname is relative, an error is signalled.
The actually returned value is the coerced value of SUBPATH by
NORMALIZE-PATHNAME.
See NORMALIZE-PATHNAME
Turns the pathname into an absolute pathname.
The given pathname is coerced using PATHNAME*
See PATHNAME*
Turns the pathname into a pathname-directory if it is not already one.
If the argument is :UP or :BACK, it is turned into a relative
pathname with the argument as its only pathname-directory-component.
If the argument is :HOME, it is turned into an absolute pathname
pointing to the home directory.
Otherwise the pathname is coerced using PATHNAME*
See PATHNAME*
See FORCE-DIRECTORY
Turns the pathname into a file pathname.
This means stripping the device, host, and directory components of the pathname. The given pathname is coerced using PATHNAME*
See PATHNAME*
Turns the pathname into a physical one if it is not already one.
The pathname is coerced using PATHNAME*
See LOGICAL-P
See CL:TRANSLATE-LOGICAL-PATHNAME
See PATHNAME*
Turns the pathname into a relative pathname.
The given pathname is coerced using PATHNAME*
See PATHNAME*
Returns the absolute root of the pathname.
Produce a namestring according to Unix rules.
- If the pathname is absolute:
- If the first directory component is :HOME, ~/ is emitted
- Otherwise / is emitted
- For every directory component, the component followed by a slash is
emitted. In the case of :UP or :BACK, they are emitted as two dots.
- The pathname name, if any, is emitted
- The pathname type, if any, is emitted following a dot.
If the pathname contains illegal characters or components, a
continuable error is signalled unless :JUNK-ALLOWED T is passed. If
the error is continued or :JUNK-ALLOWED T is passed, the component or
character is ignored. The following characters are illegal:
/ Nul
Any component that isn’t one of the following is considered illegal:
:BACK :UP :WILD :WILD-INFERIORS :UNSPECIFIC :HOME NIL string
As the representation is implementation-internal. A wild component is
outputted using "glob" syntax, meaning :WILD becomes * and
:WILD-INFERIORS becomes ** .
If STREAM is NIL, the namestring is printed to a string and returned.
See NATIVE-NAMESTRING
Returns true if the given component is unspecific.
This includes :UNSPECIFIC, NIL, and the empty string.
Moves the topmost pathname component one or more levels upwards.
Specifically, if we have a file "foo/bar/baz.jpg", and move
it upwards by one, the resulting pathname will be
"foo/baz.jpg". If the pathname is a directory-pathname then
the last directory is moved upwards by one.
