[ (index)Outputs an element from an array, map or table
Outputs an element or multiple elements from an array, map or table.
Please note that indexes in murex are counted from zero.
<stdin> -> [ element ] -> <stdout>
$variable[ element ] -> <stdout>
<stdin> -> ![ element ] -> <stdout>Return the 2nd (1), 4th (3) and 6th (5) element in an array
» ja [0..9] -> [ 1 3 5 ]
[
"1",
"3",
"5"
]Return the data-type and description of config shell syntax-highlighting
» config -> [[ /shell/syntax-highlighting ]] -> [ Data-Type Description ]
[
"bool",
"Syntax highlighting of murex code when in the interactive shell"
]Return all elements except for 1 (2nd), 3 (4th) and 5 (6th)
» a: [0..9]-> ![ 1 3 5 ]

9Return all elements except for the data-type and description
» config -> [[ /shell/syntax-highlighting ]] -> ![ Data-Type Description ]
{
"Default": true,
"Dynamic": false,
"Global": true,
"Value": true
}Indexes in murex behave like any other computer array in that all arrays start from zero (0).
As demonstrated in the examples above, [ specifies elements to include where as ![ specifies elements to exclude.
By default, index generates an error if an element doesn't exist. However you can disable this behavior in config
» config -> [ foobar ]
Error in `[` ((builtin) 2,11): Key 'foobar' not found
» config set index silent true
