The Babel library solves a similar problem while understanding more encodings. Trivial UTF-8 was written before Babel existed, but for new projects you might be better off going with Babel. The one plus that Trivial UTF-8 has is that it doesn't depend on any other libraries.

Bind extends the idea of of let and destructing to provide a uniform syntax for all your accessor needs. It combines let, destructuring-bind, with-slots, with-accessors, structure editing, property or association-lists, and multiple-value-bind and a whole lot more into a single form.

Flexi-streams is an implementation of "virtual" bivalent streams that can be layered atop real binary or bivalent streams and that can be used to read and write character data in various single- or multi-octet encodings which can be changed on the fly. It also supplies in-memory binary streams which are similar to string streams.

This library provides functions for determining the value types of Common Lisp forms, based on type information contained in the environment.

In order for this library to work the values types of variables and return types of functions have to be declared.

Macros and symbol-macros are fully expanded and all special forms, except CATCH, are supported.

Common Lisp ships with a set of powerful built in data structures including the venerable list, full featured arrays, and hash-tables. CL-containers enhances and builds on these structures by adding containers that are not available in native Lisp (for example: binary search trees, red-black trees, sparse arrays and so on), and by providing a standard interface so that they are simpler to use and so that changing design decisions becomes significantly easier.

This library extends LOG4CL system in a few ways:

* It helps with configuration of multiple appenders and layouts. * Has a facility to catch context fields and to log them. * Has a macro to log unhandled errors. * Adds a layout to write messages as JSON, which is useful for production as makes easier to parse and process such logs. * Uses the appenders which are not disabled in case of some error which again, should be useful for production.

HTML-TEMPLATE is a Common Lisp library which can be used to fill templates with arbitrary (string) values at runtime. The result does not have to be HTML.

It is loosely modeled after the Perl module HTML::Template and partially compatible with a its syntax, though both libraries contain some extensions that the other does not support.

HTML-TEMPLATE translates templates into efficient closures which can be re-used as often as needed. It uses a cache mechanism so you can update templates while your program is running and have the changes take effect immediately.
