(noob) cast string to array?

Hi. What a fantastic language. This is my first day learning using it
and I love it so far.

Great… Welcome to Ruby.

[snip]

result = result.sub(/{/,‘[’)
result = result.sub(/}/,‘]’)

What you has written is the same as (notice the ‘!’ suffix)

result.sub!(/{/,‘[’)
result.sub!(/}/,‘]’)

Above can be chained, so it becomes

result.sub!(/{/,‘[’).sub!(/}/,‘]’)

Any suggestions are more than welcome.

Try ‘gsub’

result.gsub!(/{/,‘[’).gsub!(/}/,‘]’)

sub { block way! }

result.sub!(/\{(.+)\}/) { "["+$1+"]" }

I always feel unconfortable chaining (g)sub! since the result here may
be nil.

I’d rather do

array = eval( result.gsub( /{([^}]*)}/, ‘[\1]’ ) )

I am curious to when ‘nil’ may be returned?

Here you go:

irb(main):001:0> “xyz”.gsub!(/a/, “b”)
=> nil
