%{} Object Builder

Quickly generate objects (dictionaries / maps)

Description

%{} is a way of defining objects in expressions and statements. Whenever an %{} object is outputted as a string, it will be converted to minified JSON.

Object elements inside %{} can be new line and/or comma delimited. This allows for compatibility with JSON but without the pain of accidentally invalid comma management breaking JSON parsers. However a colon is still required to separate keys from values.

Like with YAML, strings in %[] do not need to be quoted unless you need to force numeric or boolean looking values to be stored as strings.

Examples

Object passed as a JSON string

» echo %{foo: bar}
{"foo":"bar"}

Nested objects

The % prefix for the nested object is optional:

» %{foo: bar, baz: [1 2 3]}
{
    "baz": [
        1,
        2,
        3
    ],
    "foo": "bar"
}

Detail

Syntax

The syntax is pretty flexible, albeit all Murex objects are displayed as JSON objects when printed to screen or otherwise handled like a string.

The creation syntax follows these rules:

Each key needs to be followed by a colon, :.

Each value needs to be followed by either a comma, ,, new line or closing curly brace, }.

Strings can be quoted or unquoted (like with statement parameters). However any unquoted values will first be tested to see if it is a number, boolean (true of false) or null (null). Keys are always strings (str), even if they look like a number.
