5.1.2 Special variables

Special Variable: *base-build-directory* ¶

When set to a non-null value, it should be an absolute directory pathname,
which will serve as the *DEFAULT-PATHNAME-DEFAULTS* around a COMPILE-FILE,
what more while the input-file is shortened if possible to ENOUGH-PATHNAME relative to it. This can help you produce more deterministic output for FASLs.

Package

uiop/lisp-build.

Source

lisp-build.lisp.

Special Variable: *clear-configuration-hook* ¶

Package

uiop/configuration.

Source

configuration.lisp.

Special Variable: *command-line-arguments* ¶

Command-line arguments

Package

uiop/image.

Source

image.lisp.

Special Variable: *compile-check* ¶

A hook for user-defined compile-time invariants

Package

uiop/lisp-build.

Source

lisp-build.lisp.

Special Variable: *compile-file-failure-behaviour* ¶

How should ASDF react if it encounters a failure (per the ANSI spec of COMPILE-FILE) when compiling a file, which includes any non-style-warning warning.
Valid values are :error, :warn, and :ignore.
Note that ASDF ALWAYS raises an error if it fails to create an output file when compiling.

Package

uiop/lisp-build.

Source

lisp-build.lisp.

Special Variable: *compile-file-warnings-behaviour* ¶

How should ASDF react if it encounters a warning when compiling a file? Valid values are :error, :warn, and :ignore.

Package

uiop/lisp-build.

Source

lisp-build.lisp.

Special Variable: *default-encoding* ¶

Default encoding for source files.
The default value :utf-8 is the portable thing.
The legacy behavior was :default.
If you (asdf:load-system :asdf-encodings) then
you will have autodetection via *encoding-detection-hook* below, reading emacs-style -*- coding: utf-8 -*- specifications, and falling back to utf-8 or latin1 if nothing is specified.

Package

uiop/stream.

Source

stream.lisp.

Special Variable: *default-stream-element-type* ¶

default element-type for open (depends on the current CL implementation)

Package

uiop/stream.

Source

stream.lisp.

Special Variable: *encoding-detection-hook* ¶

Hook for an extension to define a function to automatically detect a file’s encoding

Package

uiop/stream.

Source

stream.lisp.

Special Variable: *encoding-external-format-hook* ¶

Hook for an extension (e.g. ASDF-ENCODINGS) to define a better mapping from non-default encodings to and implementation-defined external-format’s

Package

uiop/stream.

Source

stream.lisp.

Special Variable: *here-directory* ¶

This special variable is bound to the currect directory during calls to PROCESS-SOURCE-REGISTRY in order that we be able to interpret the :here directive.

Package

uiop/configuration.

Source

configuration.lisp.

Special Variable: *ignored-configuration-form* ¶

Have configuration forms been ignored while parsing the configuration?

Package

5.1.3 Macros

Macro: appendf (place &rest args) ¶

Append onto list

Package

uiop/utility.

Source

utility.lisp.

Macro: define-package (package &rest clauses) ¶

DEFINE-PACKAGE takes a PACKAGE and a number of CLAUSES, of the form
(KEYWORD . ARGS).
DEFINE-PACKAGE supports the following keywords:
SHADOW, SHADOWING-IMPORT-FROM, IMPORT-FROM, EXPORT, INTERN, NICKNAMES, DOCUMENTATION – as per CL:DEFPACKAGE.
USE – as per CL:DEFPACKAGE, but if neither USE, USE-REEXPORT, MIX,
nor MIX-REEXPORT is supplied, then it is equivalent to specifying
(:USE :COMMON-LISP). This is unlike CL:DEFPACKAGE for which the
behavior of a form without USE is implementation-dependent.
RECYCLE – Recycle the package’s exported symbols from the specified packages, in order. For every symbol scheduled to be exported by the DEFINE-PACKAGE, either through an :EXPORT option or a :REEXPORT option, if the symbol exists in one of the :RECYCLE packages, the first such symbol is re-homed to the package being defined.
For the sake of idempotence, it is important that the package being defined should appear in first position if it already exists, and even if it doesn’t, ahead of any package that is not going to be deleted afterwards and never created again. In short, except for special cases, always make it the first package on the list if the list is not empty.
MIX – Takes a list of package designators. MIX behaves like
(:USE PKG1 PKG2 ... PKGn) but additionally uses :SHADOWING-IMPORT-FROM to resolve conflicts in favor of the first found symbol. It may still yield
an error if there is a conflict with an explicitly :IMPORT-FROM symbol. REEXPORT – Takes a list of package designators. For each package, p, in the list, export symbols with the same name as those exported from p. Note that in the case of shadowing, etc. the symbols with the same name may not be the same symbols. UNINTERN – Remove symbols here from PACKAGE. Note that this is primarily useful when *redefining* a previously-existing package in the current image (e.g., when upgrading ASDF). Most programmers will have no use for this option. LOCAL-NICKNAMES – If the host implementation supports package local nicknames (check for the :PACKAGE-LOCAL-NICKNAMES feature), then this should be a list of nickname and package name pairs. Using this option will cause an error if the host CL implementation does not support it.
USE-REEXPORT, MIX-REEXPORT – Use or mix the specified packages as per the USE or MIX directives, and reexport their contents as per the REEXPORT directive.

Macro: while-collecting ((&rest collectors) &body body) ¶

COLLECTORS should be a list of names for collections. A collector defines a function that, when applied to an argument inside BODY, will add its argument to the corresponding collection. Returns multiple values, a list for each collection, in order.
E.g.,
(while-collecting (foo bar)
(dolist (x ’((a 1) (b 2) (c 3)))
(foo (first x))
(bar (second x))))
Returns two values: (A B C) and (1 2 3).

Macro: with-deprecation ((level) &body definitions) ¶

Given a deprecation LEVEL (a form to be EVAL’ed at macro-expansion time), instrument the
DEFUN and DEFMETHOD forms in DEFINITIONS to notify the programmer of the deprecation of the function when it is compiled or called.

Increasing levels (as result from evaluating LEVEL) are: NIL (not deprecated yet), :STYLE-WARNING (a style warning is issued when used), :WARNING (a full warning is issued when used), :ERROR (a continuable error instead), and :DELETE (it’s an error if the code is still there while at that level).

Forms other than DEFUN and DEFMETHOD are not instrumented, and you can protect a DEFUN or DEFMETHOD from instrumentation by enclosing it in a PROGN.

Function: call-with-temporary-file (thunk &key want-stream-p want-pathname-p direction keep after directory type prefix suffix element-type external-format) ¶

Call a THUNK with stream and/or pathname arguments identifying a temporary file.

The temporary file’s pathname will be based on concatenating
PREFIX (or "tmp" if it’s NIL), a random alphanumeric string,
and optional SUFFIX (defaults to "-tmp" if a type was provided)
and TYPE (defaults to "tmp", using a dot as separator if not NIL),
within DIRECTORY (defaulting to the TEMPORARY-DIRECTORY) if the PREFIX isn’t absolute.

The file will be open with specified DIRECTION (defaults to :IO),
ELEMENT-TYPE (defaults to *DEFAULT-STREAM-ELEMENT-TYPE*) and
EXTERNAL-FORMAT (defaults to *UTF-8-EXTERNAL-FORMAT*).
If WANT-STREAM-P is true (the defaults to T), then THUNK will then be CALL-FUNCTION’ed
with the stream and the pathname (if WANT-PATHNAME-P is true, defaults to T),
and stream will be closed after the THUNK exits (either normally or abnormally).
If WANT-STREAM-P is false, then WANT-PATHAME-P must be true, and then
THUNK is only CALL-FUNCTION’ed after the stream is closed, with the pathname as argument. Upon exit of THUNK, the AFTER thunk if defined is CALL-FUNCTION’ed with the pathname as argument. If AFTER is defined, its results are returned, otherwise, the results of THUNK are returned. Finally, the file will be deleted, unless the KEEP argument when CALL-FUNCTION’ed returns true.

with the arguments sent to COMPILE-FILE*, except with :OUTPUT-FILE TMP-FILE where TMP-FILE is the name of a temporary output-file.
It also checks two flags (with legacy british spelling from ASDF1), *COMPILE-FILE-FAILURE-BEHAVIOUR* and *COMPILE-FILE-WARNINGS-BEHAVIOUR*
with appropriate implementation-dependent defaults,
and if a failure (respectively warnings) are reported by COMPILE-FILE,
it will consider that an error unless the respective behaviour flag
is one of :SUCCESS :WARN :IGNORE.
If WARNINGS-FILE is defined, deferred warnings are saved to that file.
On ECL or MKCL, it creates both the linkable object and loadable fasl files. On implementations that erroneously do not recognize standard keyword arguments, it will filter them appropriately.

Function: delete-directory-tree (directory-pathname &key validate if-does-not-exist) ¶

Delete a directory including all its recursive contents, aka rm -rf.

To reduce the risk of infortunate mistakes, DIRECTORY-PATHNAME must be
a physical non-wildcard directory pathname (not namestring).

If the directory does not exist, the IF-DOES-NOT-EXIST argument specifies what happens:
if it is :ERROR (the default), an error is signaled, whereas if it is :IGNORE, nothing is done.

Furthermore, before any deletion is attempted, the DIRECTORY-PATHNAME must pass
the validation function designated (as per ENSURE-FUNCTION) by the VALIDATE keyword argument which in practice is thus compulsory, and validates by returning a non-NIL result.
If you’re suicidal or extremely confident, just use :VALIDATE T.

Coerces its argument into a PATHNAME,
optionally doing some transformations and checking specified constraints.

If the argument is NIL, then NIL is returned unless the WANT-PATHNAME constraint is specified.

If the argument is a STRING, it is first converted to a pathname via
PARSE-UNIX-NAMESTRING, PARSE-NAMESTRING or PARSE-NATIVE-NAMESTRING respectively
depending on the NAMESTRING argument being :UNIX, :LISP or :NATIVE respectively,
or else by using CALL-FUNCTION on the NAMESTRING argument;
if :UNIX is specified (or NIL, the default, which specifies the same thing),
then PARSE-UNIX-NAMESTRING it is called with the keywords
DEFAULTS TYPE DOT-DOT ENSURE-DIRECTORY WANT-RELATIVE, and
the result is optionally merged into the DEFAULTS if ENSURE-ABSOLUTE is true.

The pathname passed or resulting from parsing the string
is then subjected to all the checks and transformations below are run.

Each non-nil constraint argument can be one of the symbols T, ERROR, CERROR or IGNORE.
The boolean T is an alias for ERROR.
ERROR means that an error will be raised if the constraint is not satisfied.
CERROR means that an continuable error will be raised if the constraint is not satisfied. IGNORE means just return NIL instead of the pathname.

The ON-ERROR argument, if not NIL, is a function designator (as per CALL-FUNCTION)
that will be called with the the following arguments:
a generic format string for ensure pathname, the pathname,
the keyword argument corresponding to the failed check or transformation,
a format string for the reason ENSURE-PATHNAME failed,
and a list with arguments to that format string.
If ON-ERROR is NIL, ERROR is used instead, which does the right thing.
You could also pass (CERROR "CONTINUE DESPITE FAILED CHECK").

The transformations and constraint checks are done in this order,
which is also the order in the lambda-list:

EMPTY-IS-NIL returns NIL if the argument is an empty string.
WANT-PATHNAME checks that pathname (after parsing if needed) is not null.
Otherwise, if the pathname is NIL, ensure-pathname returns NIL.
WANT-LOGICAL checks that pathname is a LOGICAL-PATHNAME
WANT-PHYSICAL checks that pathname is not a LOGICAL-PATHNAME
ENSURE-PHYSICAL ensures that pathname is physical via TRANSLATE-LOGICAL-PATHNAME WANT-RELATIVE checks that pathname has a relative directory component
WANT-ABSOLUTE checks that pathname does have an absolute directory component ENSURE-ABSOLUTE merges with the DEFAULTS, then checks again
that the result absolute is an absolute pathname indeed.
ENSURE-SUBPATH checks that the pathname is a subpath of the DEFAULTS.
WANT-FILE checks that pathname has a non-nil FILE component
WANT-DIRECTORY checks that pathname has nil FILE and TYPE components
ENSURE-DIRECTORY uses ENSURE-DIRECTORY-PATHNAME to interpret
any file and type components as being actually a last directory component.
WANT-NON-WILD checks that pathname is not a wild pathname
WANT-WILD checks that pathname is a wild pathname
WILDEN merges the pathname with **/*.*.* if it is not wild
WANT-EXISTING checks that a file (or directory) exists with that pathname. ENSURE-DIRECTORIES-EXIST creates any parent directory with ENSURE-DIRECTORIES-EXIST. TRUENAME replaces the pathname by its truename, or errors if not possible.
RESOLVE-SYMLINKS replaces the pathname by a variant with symlinks resolved by RESOLVE-SYMLINKS. TRUENAMIZE uses TRUENAMIZE to resolve as many symlinks as possible.

Function: launch-program (command &rest keys &key input if-input-does-not-exist output if-output-exists error-output if-error-output-exists element-type external-format directory &allow-other-keys) ¶

Launch program specified by COMMAND,
either a list of strings specifying a program and list of arguments,
or a string specifying a shell command (/bin/sh on Unix, CMD.EXE on Windows) _asynchronously_.

If OUTPUT is a pathname, a string designating a pathname, or NIL (the default) designating the null device, the file at that path is used as output.
If it’s :INTERACTIVE, output is inherited from the current process;
beware that this may be different from your *STANDARD-OUTPUT*, and
under SLIME will be on your *inferior-lisp* buffer. If it’s T, output
goes to your current *STANDARD-OUTPUT* stream. If it’s :STREAM, a new stream will be made available that can be accessed via
PROCESS-INFO-OUTPUT and read from. Otherwise, OUTPUT should be a value
that the underlying lisp implementation knows how to handle.

IF-OUTPUT-EXISTS, which is only meaningful if OUTPUT is a string or a pathname, can take the values :ERROR, :APPEND, and :SUPERSEDE (the default). The meaning of these values and their effect on the case
where OUTPUT does not exist, is analogous to the IF-EXISTS parameter
to OPEN with :DIRECTION :OUTPUT.

ERROR-OUTPUT is similar to OUTPUT. T designates the *ERROR-OUTPUT*,
:OUTPUT means redirecting the error output to the output stream,
and :STREAM causes a stream to be made available via PROCESS-INFO-ERROR-OUTPUT.

IF-ERROR-OUTPUT-EXISTS is similar to IF-OUTPUT-EXIST, except that it affects ERROR-OUTPUT rather than OUTPUT.

INPUT is similar to OUTPUT, except that T designates the
*STANDARD-INPUT* and a stream requested through the :STREAM keyword
would be available through PROCESS-INFO-INPUT.

IF-INPUT-DOES-NOT-EXIST, which is only meaningful if INPUT is a string
or a pathname, can take the values :CREATE and :ERROR (the
default). The meaning of these values is analogous to the
IF-DOES-NOT-EXIST parameter to OPEN with :DIRECTION :INPUT.

ELEMENT-TYPE and EXTERNAL-FORMAT are passed on to your Lisp
implementation, when applicable, for creation of the output stream.

LAUNCH-PROGRAM returns a PROCESS-INFO object.

LAUNCH-PROGRAM currently does not smooth over all the differences between implementations. Of particular note is when streams are provided for OUTPUT or ERROR-OUTPUT. Some implementations don’t support this at all, some support only certain subclasses of streams, and some support any arbitrary
stream. Additionally, the implementations that support streams may have differing behavior on how those streams are filled with data. If data is not periodically read from the child process and sent to the stream, the child could block because its output buffers are full.

Function: parse-unix-namestring (name &rest keys &key type defaults dot-dot ensure-directory &allow-other-keys) ¶

Coerce NAME into a PATHNAME using standard Unix syntax.

Unix syntax is used whether or not the underlying system is Unix;
on such non-Unix systems it is reliably usable only for relative pathnames.
This function is especially useful to manipulate relative pathnames portably,
where it is crucial to possess a portable pathname syntax independent of the underlying OS. This is what PARSE-UNIX-NAMESTRING provides, and why we use it in ASDF.

When given a PATHNAME object, just return it untouched.
When given NIL, just return NIL.
When given a non-null SYMBOL, first downcase its name and treat it as a string.
When given a STRING, portably decompose it into a pathname as below.

#\/ separates directory components.

The last #\/-separated substring is interpreted as follows:
1- If TYPE is :DIRECTORY or ENSURE-DIRECTORY is true,
the string is made the last directory component, and NAME and TYPE are NIL.
if the string is empty, it’s the empty pathname with all slots NIL.
2- If TYPE is NIL, the substring is a file-namestring, and its NAME and TYPE
are separated by SPLIT-NAME-TYPE.
3- If TYPE is a string, it is the given TYPE, and the whole string is the NAME.

Directory components with an empty name or the name "." are removed.
Any directory named ".." is read as DOT-DOT,
which must be one of :BACK or :UP and defaults to :BACK.

HOST, DEVICE and VERSION components are taken from DEFAULTS,
which itself defaults to *NIL-PATHNAME*, also used if DEFAULTS is NIL.
No host or device can be specified in the string itself,
which makes it unsuitable for absolute pathnames outside Unix.

For relative pathnames, these components (and hence the defaults) won’t matter
if you use MERGE-PATHNAMES* but will matter if you use MERGE-PATHNAMES,
which is an important reason to always use MERGE-PATHNAMES*.

Arbitrary keys are accepted, and the parse result is passed to ENSURE-PATHNAME
with those keys, removing TYPE DEFAULTS and DOT-DOT.
When you’re manipulating pathnames that are supposed to make sense portably
even though the OS may not be Unixish, we recommend you use :WANT-RELATIVE T
to throw an error if the pathname is absolute

Function: parse-version (version-string &optional on-error) ¶

in that it doesn’t print back to itself, but the list is returned anyway.

Function: restore-image (&key lisp-interaction restore-hook prelude entry-point if-already-restored) ¶

From a freshly restarted Lisp image, restore the saved Lisp environment
by setting appropriate variables, running various hooks, and calling any specified entry point.

If the image has already been restored or is already being restored, as per *IMAGE-RESTORED-P*, call the IF-ALREADY-RESTORED error handler (by default, a continuable error), and do return immediately to the surrounding restore process if allowed to continue.

Then, comes the restore process itself:
First, call each function in the RESTORE-HOOK,
in the order they were registered with REGISTER-IMAGE-RESTORE-HOOK.
Second, evaluate the prelude, which is often Lisp text that is read,
as per EVAL-INPUT.
Third, call the ENTRY-POINT function, if any is specified, with no argument.

The restore process happens in a WITH-FATAL-CONDITION-HANDLER, so that if LISP-INTERACTION is NIL, any unhandled error leads to a backtrace and an exit with an error status.
If LISP-INTERACTION is NIL, the process also exits when no error occurs:
if neither restart nor entry function is provided, the program will exit with status 0 (success); if a function was provided, the program will exit after the function returns (if it returns), with status 0 if and only if the primary return value of result is generalized boolean true, and with status 1 if this value is NIL.

If LISP-INTERACTION is true, unhandled errors will take you to the debugger, and the result
of the function will be returned rather than interpreted as a boolean designating an exit code.

Function: run-program (command &rest keys &key ignore-error-status force-shell input if-input-does-not-exist output if-output-exists error-output if-error-output-exists element-type external-format &allow-other-keys) ¶

Run program specified by COMMAND,
either a list of strings specifying a program and list of arguments,
or a string specifying a shell command (/bin/sh on Unix, CMD.EXE on Windows); _synchronously_ process its output as specified and return the processing results
when the program and its output processing are complete.

Always call a shell (rather than directly execute the command when possible)
if FORCE-SHELL is specified. Similarly, never call a shell if FORCE-SHELL is
specified to be NIL.

Signal a continuable SUBPROCESS-ERROR if the process wasn’t successful (exit-code 0), unless IGNORE-ERROR-STATUS is specified.

If OUTPUT is a pathname, a string designating a pathname, or NIL (the default)
designating the null device, the file at that path is used as output.
If it’s :INTERACTIVE, output is inherited from the current process;
beware that this may be different from your *STANDARD-OUTPUT*,
and under SLIME will be on your *inferior-lisp* buffer.
If it’s T, output goes to your current *STANDARD-OUTPUT* stream.
Otherwise, OUTPUT should be a value that is a suitable first argument to SLURP-INPUT-STREAM (qv.), or a list of such a value and keyword arguments.
In this case, RUN-PROGRAM will create a temporary stream for the program output;
the program output, in that stream, will be processed by a call to SLURP-INPUT-STREAM, using OUTPUT as the first argument (or the first element of OUTPUT, and the rest as keywords). The primary value resulting from that call (or NIL if no call was needed)
will be the first value returned by RUN-PROGRAM.
E.g., using :OUTPUT :STRING will have it return the entire output stream as a string.
And using :OUTPUT ’(:STRING :STRIPPED T) will have it return the same string
stripped of any ending newline.

IF-OUTPUT-EXISTS, which is only meaningful if OUTPUT is a string or a
pathname, can take the values :ERROR, :APPEND, and :SUPERSEDE (the
default). The meaning of these values and their effect on the case
where OUTPUT does not exist, is analogous to the IF-EXISTS parameter
to OPEN with :DIRECTION :OUTPUT.

ERROR-OUTPUT is similar to OUTPUT, except that the resulting value is returned
as the second value of RUN-PROGRAM. T designates the *ERROR-OUTPUT*.
Also :OUTPUT means redirecting the error output to the output stream,
in which case NIL is returned.

IF-ERROR-OUTPUT-EXISTS is similar to IF-OUTPUT-EXIST, except that it
affects ERROR-OUTPUT rather than OUTPUT.

INPUT is similar to OUTPUT, except that VOMIT-OUTPUT-STREAM is used,
no value is returned, and T designates the *STANDARD-INPUT*.

IF-INPUT-DOES-NOT-EXIST, which is only meaningful if INPUT is a string
or a pathname, can take the values :CREATE and :ERROR (the
default). The meaning of these values is analogous to the
IF-DOES-NOT-EXIST parameter to OPEN with :DIRECTION :INPUT.

ELEMENT-TYPE and EXTERNAL-FORMAT are passed on
to your Lisp implementation, when applicable, for creation of the output stream.

One and only one of the stream slurping or vomiting may or may not happen
in parallel in parallel with the subprocess,
depending on options and implementation,
and with priority being given to output processing.
Other streams are completely produced or consumed
before or after the subprocess is spawned, using temporary files.

RUN-PROGRAM returns 3 values:
0- the result of the OUTPUT slurping if any, or NIL
1- the result of the ERROR-OUTPUT slurping if any, or NIL
2- either 0 if the subprocess exited with success status,
or an indication of failure via the EXIT-CODE of the process

Function: slurp-stream-form (input &key at) ¶

Read the contents of the INPUT stream as a list of forms,
then return the ACCESS-AT of these forms following the AT.
AT defaults to 0, i.e. return the first form.
AT is typically a list of integers.
If AT is NIL, it will return all the forms in the file.

The stream will not be read beyond the Nth form,
where N is the index specified by path,
if path is either an integer or a list that starts with an integer.

BEWARE: be sure to use WITH-SAFE-IO-SYNTAX, or some variant thereof

Package

Function: slurp-stream-forms (input &key count) ¶

Read the contents of the INPUT stream as a list of forms,
and return those forms.

If COUNT is null, read to the end of the stream;
if COUNT is an integer, stop after COUNT forms were read.

BEWARE: be sure to use WITH-SAFE-IO-SYNTAX, or some variant thereof

Package

Function: slurp-stream-line (input &key at) ¶

Read the contents of the INPUT stream as a list of lines,
then return the ACCESS-AT of that list of lines using the AT specifier. PATH defaults to 0, i.e. return the first line.
PATH is typically an integer, or a list of an integer and a function. If PATH is NIL, it will return all the lines in the file.

The stream will not be read beyond the Nth lines,
where N is the index specified by path
if path is either an integer or a list that starts with an integer.

Function: slurp-stream-lines (input &key count) ¶

Read the contents of the INPUT stream as a list of lines, return those lines.

Note: relies on the Lisp’s READ-LINE, but additionally removes any remaining CR from the line-ending if the file or stream had CR+LF but Lisp only removed LF.

Read no more than COUNT lines.

Function: slurp-stream-string (input &key element-type stripped) ¶

Read the contents of the INPUT stream as a string

Package

uiop/stream.

Source

stream.lisp.

Function: split-name-type (filename) ¶

Split a filename into two values NAME and TYPE that are returned. We assume filename has no directory component.
The last . if any separates name and type from from type, except that if there is only one . and it is in first position, the whole filename is the NAME with an empty type.
NAME is always a string.
For an empty type, *UNSPECIFIC-PATHNAME-TYPE* is returned.

Package

uiop/pathname.

pathname.lisp.

Function: split-native-pathnames-string (string &rest constraints &key &allow-other-keys) ¶

Given a string of pathnames specified in native OS syntax, separate them in a list, check constraints and normalize each one as per ENSURE-PATHNAME,
where an empty string denotes NIL.

Package

uiop/filesystem.

Source

filesystem.lisp.

Function: split-string (string &key max separator) ¶

Split STRING into a list of components separated by
any of the characters in the sequence SEPARATOR.
If MAX is specified, then no more than max(1,MAX) components will be returned, starting the separation from the end, e.g. when called with arguments "a.b.c.d.e" :max 3 :separator "." it will return ("a.b.c" "d" "e").

Package

uiop/utility.

Source

utility.lisp.

Function: split-unix-namestring-directory-components (unix-namestring &key ensure-directory dot-dot) ¶

Splits the path string UNIX-NAMESTRING, returning four values:
A flag that is either :absolute or :relative, indicating
how the rest of the values are to be interpreted.
A directory path — a list of strings and keywords, suitable for
use with MAKE-PATHNAME when prepended with the flag value.
Directory components with an empty name or the name . are removed.
Any directory named .. is read as DOT-DOT, or :BACK if it’s NIL (not :UP). A last-component, either a file-namestring including type extension,
or NIL in the case of a directory pathname.
A flag that is true iff the unix-style-pathname was just
a file-namestring without / path specification.
ENSURE-DIRECTORY forces the namestring to be interpreted as a directory pathname: the third return value will be NIL, and final component of the namestring will be treated as part of the directory path.

An empty string is thus read as meaning a pathname object with all fields nil.

Note that colon characters #: will NOT be interpreted as host specification. Absolute pathnames are only appropriate on Unix-style systems.

The intention of this function is to support structured component names, e.g., (:file "foo/bar"), which will be unpacked to relative pathnames.

Function: unix-namestring (pathname) ¶

Given a non-wild PATHNAME, return a Unix-style namestring for it.
If the PATHNAME is NIL or a STRING, return it unchanged.

This only considers the DIRECTORY, NAME and TYPE components of the pathname. This is a portable solution for representing relative pathnames,
But unless you are running on a Unix system, it is not a general solution to representing native pathnames.

Function: wait-process (process-info) ¶

Wait for the process to terminate, if it is still running. Otherwise, return immediately. An exit code (a number) will be returned, with 0 indicating success, and anything else indicating failure. If the process exits after receiving a signal, the exit code will be the sum of 128 and the (positive) numeric signal code. A second value may be returned in this case: the numeric signal code itself. Any asynchronously spawned process requires this function to be run before it is garbage-collected in order to free up resources that might otherwise be irrevocably lost.
