5.1.1 Special variables

Special Variable: *config* ¶

Holds the logging config as a plist. Holds package -> level mappings, using T as the default (used if logging from a package that hasn’t been configured).

Package: vom.
Source: vom.lisp.

Special Variable: *log-formatter* ¶

A function that takes a format string (user-supplied), a level string (eg ’notice’ or ’error’), a keyword of the current package, and a list of args the user supplied with the format string and returns a string of the log line we want logged.

Package: vom.
Source: vom.lisp.

Special Variable: *log-hook* ¶

Holds a function that, given a log-level, a package name, and the effective log-level for that package, returns one or more (via (values ...)) streams that this log will be sent to.

Package: vom.
Source: vom.lisp.

Special Variable: *log-stream* ¶

Holds the default stream we’re logging to.

Package: vom.
Source: vom.lisp.

Special Variable: *time-formatter* ¶

A function of 0 args that returns the current time in the desired format.

Package: vom.
Source: vom.lisp.
