This library provides miscellaneous routines.
require "misc.pl"; $result = &MiscCheckRule($_, $rule, $type); ($action, $what) = &MiscDoAction($action, $what); $newtext = &MiscTextWrap($text, $wrap, $prefix, $suffix, $keep_spaces); $result = &MiscDateFormat($fmt, $time, $msg_type); $mixed = &MiscUpperToMixed($upper); $upper = &MiscMixedToUpper($mixed);
MiscCheckRule checks a rule for a value $_. If an execution error is detected, an appropriate error is output. The result of the code executed is returned as result. If rule is an empty string, type is used to lookup a default rule for that type, if any. If rule is still an empty string, 1 is returned.
MiscDoAction executes a block of Perl code (action). If an execution error is detected, an appropriate error is output using what to name the block of code that failed. The result of the code executed is returned as result. action is only executed if it exists. If it does not, 1 is returned.
MiscTextWrap wraps a text string at a margin given by wrap. prefix is the string to begin each wrapped line. suffix is the string to terminate each wrapped line.
MiscDateFormat formats a date-time value. fmt is a string containing the symbols below.
