log5A Common Lisp logging library; CLLL? No, it’s log5. Log5 is organized around 5 things:
* Categories,
* Senders,
* Outputs,
* Messages, and
* the Context

Definitions are sorted by export status, category, package, and then by lexicographic order.
Define a category named ‘name‘. This can be a simple category like
(defcategory :error)
(defcategory prize-allocation)
of a complex category like
(defcategory :bad-thing (or :error :warning :fatal))
(defcategory non-file-foo (and (or foo bar biz) (not file-access)))
Specifically, a simple category is just a name whereas a complex category is a boolean combination of other categories (either simple or complex). See ‘category-specs‘ if you want a list of defined categories.
Define an output specification: a link between a ‘name‘ and a ‘form‘ that will be called during logging to put something in the log file.
You can specify a ‘format‘ string (as in a call to ‘format‘) with the
:format keyword argument. You can use the keyword :static? to indicate
that the form’s value will not change (e.g., the time of day is _not_
static but the process id of the current Lisp is).
Create a log-message sender and add it to the list of active
senders. Each sender has a ‘name‘, a category-spec, an output-spec and
a class (with optional initialization arguments). The ‘name‘ should be
symbol and only one sender of any particular name can exist at a time.
The category-spec is a boolean combination of categories (see ‘defcategory‘).
A sender will send any message whose message-category satisfies the sender’s
category-spec.
The output-spec is a list of outputs defined with ‘defoutput‘. You can also
include strings and the special, predefined, outputs:
* message - the text of the current log message
* context - the contents of the current context (as a list)
* category - the value of the category of the current message
Find the sender named ‘name‘ and stop it. If the sender is not active, then a ‘sender-not-found-warning‘ will be signaled unless ‘warn-if-not-found-p‘ is set to nil.
Returns a list of the defined category specs in alphatetical order.
Returns the path to the standard log5 configuration file. This is used by ‘configure-from-file‘ to setup logging activitiy. ‘Configuration-file looks in the
user’s home directory (using ‘user-homedir-pathname‘) and the directory specified by ‘*default-pathname-defaults*‘. The default is to use a file named "logging.config" but you can use the ‘:name‘ and ‘:type‘ parameters to customize this. If files exist in both directories, the ‘configuration-file‘ will use the one in the home directory unless ‘:prefer-current-directory-p‘ is true.
log5.
Returns the category whose id is id (a number).
If true, then log5 will ignore any errors that occur during logging actions. If false, log5 will enter the debugging. This is setfable.
If true, then log5 will ignore any errors that occur during logging actions. If false, log5 will enter the debugger. This is setfable.
Returns the component that handles all of log5’s bookkeeping.
Returns a list of the current output specs in alphatetical order.
