fast parsing machinery for basic types in Julia



Coverage Status Travis Build Status AppVeyor Build status

A collection of type parsers and utilities for Julia.

Installation: at the Julia REPL, Pkg.add("Parsers")

Maintenance: Parsers is maintained collectively by the JuliaData collaborators. Responsiveness to pull requests and issues can vary, depending on the availability of key collaborators.

Basic Usage

using Parsers

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

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

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

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

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

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

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