trivial-download allows you to download files from the Internet from Common Lisp. It provides a progress bar.

This library converts the elements from GObject Introspection into Common Lisp-style definitions, based on cl-gobject-introspection.

It can sometimes be useful to be able to parse chemical compounds in a user-friendly syntax into easy-to-manipulate s-expressions. You also want to be able to go in reverse. You could probably write your own parser — or you could just install the chemical-compounds package.

CLOBBER is an alternative to so-called object prevalence, and in particular to cl-prevalence. Clobber is both simpler, more flexible, and more robust than systems based on object prevalence.

Mito is yet another object relational mapper, and it aims to be a successor of Integral.

• Support MySQL, PostgreSQL and SQLite3.

• Add id (serial/uuid primary key), created_at and updated_at by default like Ruby's ActiveRecord.

• Migrations.

• Database schema versioning.

clingon is a command-line option parsing library for Common Lisp. Its features include:

• Support for subcommands

• Support for command aliases

• Support for short and long options

• Related options may be grouped into categories

• Short options may be collapsed into a single argument, as in -xyz

• Long options support the notations --long-opt arg and --long-opt=arg

• Automatic generation of help/usage information for commands and subcommands

• Out-of-the-box support for --version and --help

• Support for various kinds of options including string, integer, boolean, switch, enum, list, counter, filepath, etc.

• Subcommands can look up global options defined in parent commands

• Support for required options

• Options can be initialized via environment variables

• Single interface for creating options using CLINGON:MAKE-OPTION

• Generate documentation for your command-line application

• Support for pre-hook and post-hook actions for commands, which allow invoking functions before and after the respective handler of the command is executed

• Support for Bash and Zsh completions

• Extensibility, so if you don't find something you need you can extend it by developing a new option kind, or even a new mechanism for initializing options, e.g., by looking up an external key/value store

ALEXA is a tool similar to lex or flex for generating lexical analyzers. Unlike tools like lex, however, ALEXA defines a domain-specific language within your Lisp program, so you don't need to invoke a separate tool.

This is a utility library providing access to the mmap family of functions in a portable way. It allows you to directly map a file into the address space of your process without having to manually read it into memory sequentially. Typically this is much more efficient for files that are larger than a few Kb.

This library implements the -> and ->> macros from Clojure, as well as several expansions on the idea.

cl-libxml2 is high-level Common Lisp wrapper around the libxml2 and libxslt libraries.

• Interfaces for tree manipulation (like cxml-stp).

• Interface for HTML 4.0 non-validating parsers.

• Specific APIs to process HTML trees, especially serialization.

• XPath API.

• XSLT API.

• Custom URL resolvers.

• XPath extension functions.

• XSLT extension elements.

• Translates libxml2 and libxslt errors to Lisp conditions.

• Extends the Common Lisp iterate library with custom drivers for child nodes enumeration, etc.

• The XFACTORY system provides a simple and compact syntax for XML generation.

Drakma is a full-featured HTTP client implemented in Common Lisp. It knows how to handle HTTP/1.1 chunking, persistent connections, re-usable sockets, SSL, continuable uploads, file uploads, cookies, and more.

This package provides an enhanced EVAL-WHEN macro that supports a shorthand for (eval-when (:compile-toplevel :load-toplevel :execute) ...), addressing concerns about verbosity.

cl-pass is a password hashing and verification library.

This package contains a support library for other hu.dwim systems.

Doctests for Lisp.

Static dispatch is a Common Lisp library, inspired by inlined-generic-function, which allows standard Common Lisp generic function dispatch to be performed statically (at compile time) rather than dynamically (runtime). This is similar to what is known as "overloading" in languages such as C++ and Java.

The purpose of static dispatch is to provide an optimization in cases where the usual dynamic dispatch is too slow, and the dynamic features of generic functions, such as adding/removing methods at runtime are not required. An example of such a case is a generic equality comparison function. Currently generic functions are considered far too slow to implement generic arithmetic and comparison operations when used heavily in numeric code.

This package provides an enhanced version of typep that is exactly like the one in the Lisp spec, except it can also accept a single type argument, in which case it returns the appropriate closure.

This package provides the LOCAL-TIME extensions for the cl-postgres ASDF system of postmodern.

A library and command line utility to automatically indent Common Lisp source files.

This library is a path strings manipulation library inspired by Python's os.path. All functionality from os.path is supported on major operation systems.

The philosophy behind is to use simple strings and "dumb" string manipulation functions to handle paths and filenames. Where possible the corresponding OS system functions are called.

This package provides Common Lisp support for reading the Terragen .TER format. The format specification can be found at https://planetside.co.uk/wiki/index.php?title=Terragen_.TER_Format

CXML implements a namespace-aware, validating XML 1.0 parser as well as the DOM Level 2 Core interfaces. Two parser interfaces are offered, one SAX-like, the other similar to StAX.

deeds allows for efficient event delivery to multiple handlers with a complex event filtering system.

This library provides modern file handling for Common Lisp, which avoids many of the pitfalls of pathnames.
