Parsing Array of Strings to Object in Julia

I have the following string

l = "['name1', 'name2', 'name3']"

Now, I'd like to turn this into a proper array of strings, such as:

["name1","name2","name3"]

I know that one can use Meta.parse in Julia, to turn an expression into a Julia object. The following code works:

Meta.parse("['a','b','c']")

But when each string has more than one character, Julia gives the following error message:

Base.Meta.ParseError("character literal contains multiple characters")

Any idea on how to solve this problem?

You could use replace to change the ''s (which are used for chars) into "'s (which are used for strings) in the string before parsing it:

Meta.parse(replace(l, "'" => '"'))

Use JSON3 package:

julia> JSON3.read(replace("['name1', 'name2', 'name3']", "'"=>"\""))
3-element JSON3.Array{String,Base.CodeUnits{UInt8,String},Array{UInt64,1}}:
 "name1"
 "name2"
 "name3"
