The Bell

Sometimes Epsilon will ring the computer's bell to alert you to certain conditions. (Well, actually it sounds more like a beep, but we call it a bell anyway.) You can enable or disable the bell completely by setting the want-bell variable. Epsilon will never try to beep if want-bell has a value of zero.

For finer control of just when Epsilon rings the bell, you can set the variables listed in the table using the set-variable command, described in Variables. A nonzero value means Epsilon will ring the bell when the indicated condition occurs. By default, all these variables but bell-on-abort have the value 1, so Epsilon rings the bell on almost all of these occasions.

 Variable  When Epsilon Beeps, if Nonzero
 bell-on-abort  You abort a command, press an unbound key, or Epsilon reports an error.
 bell-on-autosave-error  Autosaving can't write files.
 bell-on-bad-key  You press an illegal option at a prompt.
 bell-on-completion  Completion finds no matches.
 bell-on-date-warning  Epsilon notices that a file has changed on disk.
 bell-on-read-error  Epsilon cannot read a file.
 bell-on-search  Search finds no more matches.
 bell-on-write-error  Epsilon cannot write a file.

In some environments, the beep-duration variable specifies the duration of the beep, in hundredths of a second. The beep-frequency variable specifies the frequency of the bell in hertz.

Instead of making a sound for the bell, you can have Epsilon invert the mode line of each window for a time according to the value of beep-duration by setting beep-frequency to zero, and beep-duration to any nonzero value.

Under Windows, Epsilon doesn't use the beep-duration or beep-frequency variables. It uses a standard system sound instead. Under Unix, Epsilon recognizes a beep-frequency of zero and flashes the screen in some fashion, but otherwise ignores these variables.
