6.4 Terminal windows and message logs

6.4.1 Controlling use of a terminal window

A graphical Macintosh application does not usually have a console/terminal window.

You can achieve this by supplying the keyword argument console :input when delivering your application.

6.4.2 Logging debugging messages

Output to *terminal-io* from an application without a console/terminal window will not ordinarily be visible to the user, so debugging messages should be written to a log file.

Log files are recommended for any complex application as they make it easier for you to get information back from your users.

You can use dbg:log-bug-form for logging errors. See the LispWorks User Guide and Reference Manual for details.
