Create JSON Array (ja)

A sophisticated yet simply way to build a JSON array

Description

Murex has a pretty sophisticated builtin for generating JSON arrays. It works a little bit like Bash’s {1..9} syntax but includes a few additional nifty features.

Please note that while this builtin is not marked for deprecation, it has been superseded by the %[] tokens. (read more)

Usage

ja [start..end] -> <stdout>
ja [start..end.base] -> <stdout>
ja [start..end,start..end] -> <stdout>
ja [start..end][start..end] -> <stdout>

Examples

» ja [1..5]
[
    "1",
    "2",
    "3",
    "4",
    "5"
]
» ja [Monday..Sunday]
[
    "Monday",
    "Tuesday",
    "Wednesday",
    "Thursday",
    "Friday",
    "Saturday",
    "Sunday"
]

Please note that as per the first example, all arrays generated by ja are arrays of strings - even if you’re command is ranging over integers.
