Usage: set [no|inv]variable[=value] [ variable ... ]
Usage: toggle variable [variable ... ]
Usage: unset variable [variable ... ]
Usage: reset variable [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. strings must be enclosed in quotes if they contain spaces or tabs. You may also use the ``C'' escape sequences \n and \t 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 the action to be carried out as if you had answered ``no.'' A value of ask-yes will cause a prompt with a default answer of ``yes'' and ask-no will provide a default answer of ``no.''
Prefixing a variable with ``no'' will unset it. Example: set noaskbcc.
For boolean variables, you may optionally prefix the variable name with
inv to toggle the value (on or off). This is useful when writing
macros. Example: set invsmart_wrap.
The toggle command automatically prepends the inv prefix to all
specified variables.
The unset command automatically prepends the no prefix to all
specified variables.
Using the enter-command function in the index menu, you can query the value of a variable by prefixing the name of the variable with a question mark:
set ?allow_8bit
The question mark is actually only required for boolean and quadoption variables.
The reset command resets all given variables to the compile time
defaults (hopefully mentioned in this manual). If you use the command
set and prefix the variable with ``&'' this has the same
behavior as the reset command.
With the reset command there exists the special variable ``all'',
which allows you to reset all variables to their system defaults.
