6.1.1 Special variables

Special Variable: *date-time-format* ¶

The default format to use when printing dates and times.

* %% - A ’%’ character
* %d - Day of the month as a decimal number [01-31]
* %e - Same as %d but does not print the leading 0 for days 1 through 9 [unlike strftime[], does not print a leading space]
* %H - Hour based on a 24-hour clock as a decimal number [00-23]
*%I - Hour based on a 12-hour clock as a decimal number [01-12]
* %m - Month as a decimal number [01-12]
* %M - Minute as a decimal number [00-59]
* %S - Second as a decimal number [00-59]
* %w - Weekday as a decimal number [0-6], where Sunday is 0
* %y - Year without century [00-99]
* %Y - Year with century [such as 1990]

This code is borrowed from the ‘format-date‘ function in [metatilities-base][].

6.1.2 Ordinary functions

Function: backtrace-string (&rest args) ¶

Package

trivial-backtrace.

Source

map-backtrace.lisp.

Function: map-backtrace (function) ¶

Package

trivial-backtrace.

Source

map-backtrace.lisp.

Function: print-backtrace (error &key output if-exists verbose) ¶

Send a backtrace for the error ‘error‘ to ‘output‘.

The keywords arguments are:

* :output - where to send the output. This can be:

* a string (which is assumed to designate a pathname)
* an open stream
* nil to indicate that the backtrace information should be returned as a string

* if-exists - what to do if output designates a pathname and the pathname already exists. Defaults to :append.

* verbose - if true, then a message about the backtrace is sent to \*terminal-io\*. Defaults to ‘nil‘.

If the ‘output‘ is nil, the returns the backtrace output as a string. Otherwise, returns nil.

Package

trivial-backtrace.

Source

backtrace.lisp.

Function: print-backtrace-to-stream (stream) ¶

Send a backtrace of the current error to stream.

Stream is assumed to be an open writable file stream or a string-output-stream. Note that ‘print-backtrace-to-stream‘ will print a backtrace for whatever the Lisp deems to be the *current* error.

Package

trivial-backtrace.

Source

backtrace.lisp.

Function: print-condition (condition stream) ¶

Print ‘condition‘ to ‘stream‘ using the pretty printer.
