Basic Usage

using Parsers

# basic int/float parsing
x = Parsers.parse(Int, "101")
y = Parsers.parse(Float64, "101.101")

# use comma as decimal
y2 = Parsers.parse(Float64, "101,101", Parsers.Options(decimal=','))

# Bool parsing
z = Parsers.parse(Bool, "true")

# Date/DateTime parsing
using Dates
a = Parsers.parse(Date, "2018-01-01")

# custom dateformat
b = Parsers.parse(Date, "01/20/2018", Parsers.Options(dateformat="mm/dd/yyyy"))

# will throw on invalid values
Parsers.parse(Int, "abc")

# tryparse will return `nothing` on invalid values
y = Parsers.tryparse(Int, "abc")
