Programs can customize how their warnings appear by binding the variables described in this section.
This list defines the meaning and severity order of the warning severity levels. Each element defines one severity level, and they are arranged in order of decreasing severity.
Each element has the form (level string function),
where level is the severity level it defines. string specifies
the textual description of this level. string should use ‘%s’ to
specify where to put the warning type information, or it can omit the
‘%s’ so as not to include that information.
The optional function, if non-nil, is a function to call with
no arguments, to get the user's attention.
Normally you should not change the value of this variable.
If non-nil, the value is a function to generate prefix text for
warnings. Programs can bind the variable to a suitable function.
display-warning calls this function with the warnings buffer current,
and the function can insert text in it. That text becomes the beginning of
the warning message.
The function is called with two arguments, the severity level and its entry
in warning-levels. It should return a list to use as the entry (this
value need not be an actual member of warning-levels). By
constructing this value, the function can change the severity of the
warning, or specify different handling for a given severity level.
If the variable's value is nil then there is no function to call.
Programs can bind this variable to t to say that the next warning
should begin a series. When several warnings form a series, that means to
leave point on the first warning of the series, rather than keep moving it
for each warning so that it appears on the last one. The series ends when
the local binding is unbound and warning-series becomes nil
again.
The value can also be a symbol with a function definition. That is
equivalent to t, except that the next warning will also call the
function with no arguments with the warnings buffer current. The function
can insert text which will serve as a header for the series of warnings.
Once a series has begun, the value is a marker which points to the buffer position in the warnings buffer of the start of the series.
The variable's normal value is nil, which means to handle each
warning separately.
When this variable is non-nil, it specifies a fill prefix to use for
filling each warning's text.
This variable specifies the format for displaying the warning type in the
warning message. The result of formatting the type this way gets included
in the message under the control of the string in the entry in
warning-levels. The default value is " (%s)". If you bind it
to "" then the warning type won't appear at all.
