EasyConfig
EasyConfig provides a simple nested AbstractDict{Symbol, Any} data structure.
Advantages over dictionaries/named tuples:
1) Intermediate levels are created on the fly:
c = Config().one.two.three = 1vs.
c = OrderedDict(:one => OrderedDict(:two => OrderedDict(:three => 1)))
c = (one = (two = (three = 1,),),)
c = (; one = (;two = (;three = 1)))2) Values can be accessed with getproperty:
c.one.two.three == 1 # same as NamedTuplevs.
c[:one][:two][:three] == 13) Getting/setting can be done with get/set property/index:
(for the purpose of making Symbols easier to work with)
c.why."would you"["need to do this?"] = "No reason"
c."why"[var"would you"]."need to do this?" == "No reason"Conversion to JSON
Simply JSON3.write it!
Gotchas
If you try to access something that doesn't exist, an empty Config() will sit there (a consequence of creating intermediate levels on the fly):
c = Config()
c.one.two.three.four.five.six == Config()Configs with delete_empty!(::Config).
Example (Try this in Pluto 🎈 !)
begin
using Random, EasyConfig, JSON3
function plot(config)
id = randstring(20)

<script>
var data = $(JSON3.write(config.data))
var layout = $(JSON3.write(config.layout))
