spam+The score commands adds value to +a message's score if pattern matches it. +pattern is a string in the format described in the +patterns section (note: For efficiency +reasons, patterns which scan information not available in the index, +such as~b,~Bor +~h, may not be used). value is +a positive or negative integer. A message's final score is the sum +total of all matching score entries. However, you +may optionally prefix value with an equal sign +(â=â) to cause evaluation to stop at a particular entry if +there is a match. Negative final scores are rounded up to 0. ++The unscore command removes score entries from the +list. You must specify the same pattern specified +in the score command for it to be removed. The +pattern â*â is a special token which means to clear the +list of all score entries. +

The following commands are available to manipulate and query variables:
Usage:
set{ [no|inv]variable|variable=value- } [...]
toggle+ } [...]togglevariable[variable-...]
unset+...]unsetvariable[variable-...]
reset+...]resetvariable[variable...]-This command is used to set (and unset) configuration variables. There are four basic types of variables: -boolean, number, string and quadoption. boolean variables can be -set (true) or unset (false). number variables can be -assigned a positive integer value. -string variables consist of any number of printable characters and -must be enclosed in quotes if they contain spaces or tabs. You -may also use the escape sequences â\nâ and â\tâ for newline and tab, respectively. -quadoption variables are used to control whether or not to be prompted -for certain actions, or to specify a default action. A value of yes -will cause the action to be carried out automatically as if you had answered -yes to the question. Similarly, a value of no will cause the -action to be carried out as if you had answered âno.â A value of -ask-yes will cause a prompt with a default answer of âyesâ and -ask-no will provide a default answer of âno.â -
-Prefixing a variable with ânoâ will unset it. Example:

source+Note that there is a space between +<enter-command>and the set +configuration command, preventing Mutt from recording the +macro's commands into its history. ++Variables are always assigned string values which Mutt parses into its +internal representation according to the type of the variable, for +example an integer number for numeric types.

As a result, any variable can be assigned any value given that +its content is valid for the target. This also counts for custom +variables which are of type string. In case of parsing errors, Mutt will +print error messages. Example 3.18, âType conversions using variablesâ demonstrates type +conversions. +
Example 3.18. Type conversions using variables
+set my_lines = "5" # value is string "5" +set pager_index_lines = $my_lines # value is integer 5 + +set my_sort = "date-received" # value is string "date-received" +set sort = "last-$my_sort" # value is sort last-date-received + +set my_inc = $read_inc # value is string "10" (default of $read_inc) +set my_foo = $my_inc # value is string "10" ++These assignments are all valid. If, however, the value of +
$my_lineswould have been +âfiveâ (or something else that cannot be parsed into a +number), the assignment to +$pager_index_lineswould have +produced an error message. ++Type conversion applies to all configuration commands which take +arguments.
