Create JSON Array (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Please note that while this builtin is not marked for deprecation, it has been superseded by the %[]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.
