5.1.2 Special variables

Special Variable: *break-on-warn-user*

set to T if you’d like to stop in warn-user

Package

utils.

Source

utils.lisp.

Special Variable: *current-file*

The file currently being worked on by OPEN-AUDIO-FILE

Package

audio-streams.

Source

audio-streams.lisp.

Special Variable: *get-audio-info*

Controls whether the parsing functions parse audio info like bit-rate, etc

Package

audio-streams.

Source

audio-streams.lisp.

Special Variable: *raw-tags*

Package

Source

abstract-tag.lisp.

Special Variable: *standard-optimize-settings*
Package

5.1.3 Macros

Macro: aif (test-form then-form &optional else-form)
Package

utils.

Source

utils.lisp.

Macro: awhen (test-form &body body)
Package

utils.

Source

utils.lisp.

Macro: dbg (tag &rest exprs)

debug macro for print-debugging:
TAG is typically a constant string or keyword to identify who is printing, but can be an arbitrary expression returning a tag to be princ’ed first;
if the expression returns NIL, nothing is printed.
EXPRS are expressions, which when the TAG was not NIL are evaluated in order, with their source code then their return values being printed each time. The last expression is *always* evaluated and its multiple values are returned, but its source and return values are only printed if TAG was not NIL; previous expressions are not evaluated at all if TAG returned NIL.
The macro expansion has relatively low overhead in space or time.
