7347 | 2108 @deffn {Command} clear [options] pattern @dots{}\n\ |
3361 | 2109 Delete the names matching the given patterns from the symbol table. The\n\ |
2110 pattern may contain the following special characters:\n\ | |
4016 | 2111 \n\ |
3361 | 2112 @table @code\n\ |
2113 @item ?\n\ | |
2114 Match any single character.\n\ | |
668 | 2115 \n\ |
3361 | 2116 @item *\n\ |
2117 Match zero or more characters.\n\ | |
2118 \n\ | |
2119 @item [ @var{list} ]\n\ | |
2120 Match the list of characters specified by @var{list}. If the first\n\ | |
2121 character is @code{!} or @code{^}, match all characters except those\n\ | |
2122 specified by @var{list}. For example, the pattern @samp{[a-zA-Z]} will\n\ | |
2123 match all lower and upper case alphabetic characters.\n\ | |
2124 @end table\n\ | |
2125 \n\ | |
2126 For example, the command\n\ | |
593 | 2127 \n\ |
3361 | 2128 @example\n\ |
2129 clear foo b*r\n\ | |
2130 @end example\n\ | |
2131 \n\ | |
2132 @noindent\n\ | |
2133 clears the name @code{foo} and all names that begin with the letter\n\ | |
2134 @code{b} and end with the letter @code{r}.\n\ | |
668 | 2135 \n\ |
3361 | 2136 If @code{clear} is called without any arguments, all user-defined\n\ |
2137 variables (local and global) are cleared from the symbol table. If\n\ | |
2138 @code{clear} is called with at least one argument, only the visible\n\ | |
2139 names matching the arguments are cleared. For example, suppose you have\n\ | |
2140 defined a function @code{foo}, and then hidden it by performing the\n\ | |
2141 assignment @code{foo = 2}. Executing the command @kbd{clear foo} once\n\ | |
2142 will clear the variable definition and restore the definition of\n\ | |
2143 @code{foo} as a function. Executing @kbd{clear foo} a second time will\n\ | |
2144 clear the function definition.\n\ | |
2145 \n\ | |
7347 | 2146 The following options are available in both long and short form\n\ |
2147 @table @code\n\ | |
2148 @item -all, -a\n\ | |
2149 Clears all local and global user-defined variables and all functions\n\ | |
2150 from the symbol table.\n\ | |
2151 \n\ | |
2152 @item -exclusive, -x\n\ | |
2153 Clears the variables that don't match the following pattern.\n\ | |
2154 \n\ | |
2155 @item -functions, -f\n\ | |
2156 Clears the function names and the built-in symbols names.\n\ | |
2157 @item -global, -g\n\ | |
2158 Clears the global symbol names.\n\ | |
2159 @item -variables, -v\n\ | |
2160 Clears the local variable names.\n\ | |
