1 Introduction

UIOP, the Utilities for Implementation- and OS- Portability

UIOP is the portability layer of ASDF. It provides utilities that abstract over discrepancies between implementations, between operating systems, and between what the standard provides and what programmers actually need, to write portable Common Lisp programs.

It is organized by topic in many files, each of which defines its own package according to its topic: e.g pathname.lisp will define package UIOP/PATHNAME and contain utilities related to the handling of pathname objects. All exported symbols are reexported in a convenience package UIOP, except for those from UIOP/COMMON-LISP. We recommend package UIOP be used to access all the symbols.

The files that constitute UIOP are, in dependency loading order:

• package: deals with packages and their symbols, most notably including define-package, a variant of defpackage capable of hot-upgrade, or symbol-call and find-symbol* that are also useful for use in .asd files before packages have been defined.

• common-lisp: lets you paper over various sub-standard implementations. Big offenders are Corman, GCL, Genera, MCL, none of them regularly maintained. Supported without serious issues are: ABCL, Allegro, CCL, CMUCL, CLASP, CLISP, ECL, LispWorks, MKCL, SBCL, SCL, XCL.

• utility: provides macros and functions that do not involve I/O; it handles control-flow, (p)lists, characters, strings, functions, classes, conditions, "stamps" (real number or boolean for +/- infinity), etc. It also sports uiop-debug, a useful tool to help you debug programs.

• version: manages ASDF-style versioning and a related with-deprecation facility to gracefully declare that users should stop using some deprecated functions.

• os: extracts information from your environment, including an ABI identifier, features that distinguish Unix vs Windows, getenv, hostname, getcwd and chdir, etc.

• pathname: overcomes the gruesome non-portability trap that are CL pathnames (and their lovecraftian "logical" variant), offering a vast array of functions and a sensible, usable abstraction to specify relative pathnames. It has a function merge-pathnames* to use instead of merge-pathnames, or even better, subpathname and its variant subpathname*; it has also plenty of functions for dealing with pathnames being directory vs file, physical vs logical, absolute vs relative, and more.

• filesystem: provides portable access to the filesystem, inspecting it, only using truename when desired, using native OS namestrings, atomic file renaming, creating or deleting directories, etc.

• stream: portably deals with *stderr* vs *error-output*, character encodings (external formats), element types, safe reading and writeing, opening files, using temporary files, flushing output buffers, providing format-like designators for streams, consuming or copying streams, concatenating streams or files, copying files, etc.

• image: portably deals with images, dumping them, restoring from them, registering hooks to run at suitable events in the image lifetime, printing backtraces, handling fatal conditions, using or avoiding debug modes, accessing command line arguments or quitting the process.

• lisp-build: portably compiles Common Lisp code, handles compilation results, muffles uninteresting conditions, saves and restores deferred warnings, runs hooks around compilation (to e.g. control optimizations or syntax), identifies the pathname of the current file, combines FASLs, etc.

• launch-program: semi-portably launches a program as an asynchronous external subprocess. Available functionality may depend on the underlying implementation.

• run-program: fully portably runs a program as a synchronous external subprocess, feed it input and capture its output. Most implementations also allow interactive console subprocesses.

• configuration: portably locates and parses configuration files, using best practices to define and validate syntax, search standard paths, let users specify pathnames or pathname patterns, etc.

• backward-driver: provides backward-compatibility with earlier incarnations of this library (i.e. ASDF internals that have leaked, ASDF-UTILS, or older versions of UIOP).

• driver: reexports all the above utilities in a single package UIOP.

Documentation

Each file starts with a package definition form that lists the exported symbols.

All the exported functions, macros and variables ought to have proper docstrings. If not, then it's a legitimate bug that we invite you to report.

You can extract a manual from the docstrings by running make in the directory uiop/doc.

Other automated tools may hopefully extract all that information and make a webpage from it, at which point it would be nice to insert a link here. But many tools fail to extract useful data.

Tools with which you can extract all the documentation include Declt and HEΛP. See the Quickref UIOP reference manual https://quickref.common-lisp.net/uiop.html as extracted by Declt.

There is also a pre-extracted HEΛP documentation page http://bimib.disco.unimib.it/people/Marco.Antoniotti/Projects/CL/HELAMBDAP/tests/asdf-uiop/docs/html/dictionary/dictionary.html. Note however that the HEΛP interface is not very usable at this time: it isn't obvious at all that you can indeed use a scrollbar on the right of the top left side panel to navigate the many packages; once you click on the package you're interested in, you can see its defined symbols.

Another automated documentation tool is quickdocs, but unhappily, at the time of this writing, it only extracts information from the first package (see bug #24): http://quickdocs.org/uiop/api

Using UIOP

UIOP is part of ASDF 3, and any modern Common Lisp implementation will have all of UIOP available when you (require "asdf"). NB: (require :asdf) also works on all implementations but CLISP. Every implementation has sported ASDF 3 for years, and if yours only provides ASDF 2, we recommend you install ASDF 3 on top of it, using the facility in tools/install-asdf.lisp.

If you need some functionality only available in a recent version of UIOP, but cannot or will not upgrade ASDF, UIOP is also distributed separately; see e.g. in Quicklisp. You may then have to load it like any other library, by adding "uiop" or some versioned constraint (:version "uiop" "3.2.0") in your system's :depends-on declaration, or at the REPL using:

(asdf:load-system :uiop)

When refering to symbols in UIOP, we recommend you either have your package :use the package :uiop or :import-from it, or that you shall use uiop: as a prefix to the symbols. Please DO NOT refer to specific subpackages such as uiop/run-program from the outside of UIOP, because functions may occasionally be moved from one internal package to the other, without notification. They have in the past and will in the future.

When to use UIOP

UIOP is the ideal tool to use when:

• You need utilities that are always available, portably, with no installation needed.
• You work in a cooperative environment, where the user is a developer who understands what he's doing and is trusted not to be malicious.
• You are writing a build system, build tools, developer-facing tools.
• You are writing bootstrap scripts, in which you cannot suppose that any third-party library has been installed (yet), much less a C compiler or any external tool.
• You are trying to make existing Common Lisp code more robust and portable, or replacing developer "scripts" (in shell, perl, python, ruby, js, and other blub languages) with Common Lisp code, but without concerns about either end-user usability or security (at the very least, you, not end-users, are fully controlling pathnames, and filtering off or portably encoding any unusual character, etc.)

UIOP is the wrong tool when:

• You need to have total control on syscalls, to use special characters in pathnames, to handle symlinks yourself, or otherwise to have low-level system access.
• You work in an adversarial environment, where some users are stupid, uneducated or outright malicious, and cannot be trusted not to try and abuse the system with pathnames, symlinks, race conditions, etc. (or be tricked into it by attackers).
• You are writing end-user facing tools that pass along user-provided pathnames, with bad usability implications if a user tries to use weird pathnames, or even security implications if an attackers crafts bad pathnames or filesystem setups.

In those latter cases, we recommend you use IOlib, or osicat, or some similar library that isn't as portable as UIOP, but provides fine-grained control over low-level system access. Also, please use extreme caution.

Some history

UIOP, formerly known as ASDF-DRIVER (the package and system nicknames are deprecated), evolved from ASDF 2's internal utilities and portability layer. It has since fully superseded functionality from the following libraries: ASDF-UTILS (UIOP carries on the ASDF 2 utilities that this exported), CL-FAD (UIOP completely replaces it with better design and implementation), CL-LAUNCH (UIOP took its image and command-line argument handling), EXTERNAL-PROGRAM, TRIVIAL-SHELL and XCVB-DRIVER (UIOP's run-program and now launch-program evolved from XCVB-DRIVER, from which UIOP also initially got its condition muffling), SLIME's swank-loader (UIOP has better compilation and ABI identification), TRIVIAL-BACKTRACE (UIOP/IMAGE has all of it and more), etc.

UIOP also captures a large subset of the functionality from TRIVIAL-FEATURES, and a small subset of the functionality from ALEXANDRIA or FARE-UTILS.

We recommend you use UIOP instead of any of the above, where applicable, since UIOP is more portable, more robust, more ubiquitous, better designed, better documented, etc. If you see any way in which UIOP isn't superior, please tell us: we're interested in improving it so it become s

Description

Portability library for Common Lisp programs

Long Description

UIOP provides runtime support for Common Lisp programs:
Basic general-purpose utilities that are in such a need that you can’t portably construct a complete program without using some of them. UIOP replaces ASDF/DRIVER and ASDF-UTILS, and offers a superset of the functionality provided by CL-FAD, EXTERNAL-PROGRAM, TRIVIAL-SHELL, TRIVIAL-BACKTRACE and a lot of the functionality formerly provided by CL-LAUNCH, XCVB-DRIVER, TRIVIAL-FEATURES, plus a tiny subset of functionality from ALEXANDRIA and FARE-UTILS.
It is transcluded into asdf.lisp together with ASDF/DEFSYSTEM, so if you did (require "asdf") you already have a matching UIOP loaded.

utility.lisp (file)

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.

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/lisp-build

Source

lisp-build.lisp (file)

Special Variable: *output-translation-function*

Hook for output translations.

This function needs to be idempotent, so that actions can work whether their inputs were translated or not,
which they will be if we are composing operations. e.g. if some create-lisp-op creates a lisp file from some higher-level input, you need to still be able to use compile-op on that lisp file.

Special Variable: *utf-8-external-format*

Default :external-format argument to pass to CL:OPEN and also
CL:LOAD or CL:COMPILE-FILE to best process a UTF-8 encoded file.
On modern implementations, this will decode UTF-8 code points as CL characters. On legacy implementations, it may fall back on some 8-bit encoding,
with non-ASCII code points being read as several CL characters;
hopefully, if done consistently, that won’t affect program behavior too much.

Macro: defgeneric* NAME FORMALS &rest REST

Package

uiop/utility

Source

utility.lisp (file)

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:
USE, SHADOW, SHADOWING-IMPORT-FROM, IMPORT-FROM, EXPORT, INTERN – as per CL:DEFPACKAGE. 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.

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.

STREAM and PATHNAME (if respectively specified) are bound corresponding
to a newly created temporary file ready for I/O, as per CALL-WITH-TEMPORARY-FILE.
At least one of STREAM or PATHNAME must be specified.
If the STREAM is not specified, it will be closed before the BODY is evaluated.
If STREAM is specified, then the :CLOSE-STREAM label if it appears in the BODY,
separates forms run before and after the stream is closed.
The values of the last form of the BODY (not counting the separating :CLOSE-STREAM) are returned. Upon success, the KEEP form is evaluated and the file is is deleted unless it evaluates to TRUE.

Function: access-at OBJECT AT

Given an OBJECT and an AT specifier, list of successive accessors,
call each accessor on the result of the previous calls.

a keyword, meaning a call to GETF,
NIL, meaning identity,
a function or other symbol, meaning itself,
or a list of a function designator and arguments, interpreted as per ENSURE-FUNCTION. As a degenerate case, the AT specifier may be an atom of a single such accessor instead of a list.
