Added in version 8.9.0.5 of package base.
parameter
config:report-configuration?
A configuration is a hash table with the following keys:
'datum-to-what — a procedure of one argument used to get a noun describing an expected datum, which appears in a pattern either with ~datum , as “self-quoting,” or so on. The procedure’s argument is the datum value. The result must be either a string or a list containing two strings; if two strings are provided, the first is used when a singular noun is needed, and the second is used as a plural noun.
The default configuration returns '("literal symbol""literal symbols") for a symbol and '("literal""literals") for any other datum value.
'datum-to-string — a procedure of one argument, used to convert the datum value to a string that is included in the error message. The procedure’s argument is the datum value, and the result must be a string.
The default configuration formats a symbol value using (format "`~s'"v) any other datum value using (format "~s"v).
'literal-to-what — a procedure of one argument used to get a noun describing an expected literal identifier, which appears in a pattern with ~literal , as declared with #:literals, or so on. The procedure’s argument is an identifier when available, or a symbol when only simplified information has been preserved. The result must be either a string or a list containing two strings, like the result for a 'datum-to-what procedure.
The default configuration returns '("identifier""identifiers").
'literal-to-string — a procedure of one argument, used to convert a literal identifier or symbol to a string that is included in the error message.
The default configuration formats a symbol value using (format "`~s'"v), and it formats an identifier the same after extracting its symbol with syntax-e .
Changed in version 8.15.0.4 of package base: Changed parameter to cross-phase persistent.
