Readme

Extensible C# string parser with decent defaults, .NET primitives support, enum support, nullable support.

using Nerven.StringParser.Core.Build;
var builder = new StringParserBuilder
{
PreSteps =
{
NullableParseStep.Default, // Adds Nullable<> suppoort
},
Steps =
{
EnumParseStep.Ordinal, // Parses enums
CustomParseStep.Define(typeof(ushort), _s => // Custom parsing
{
ushort _value;
return ushort.TryParse(_s, out _value)
? ParseStep.Valid((ushort)(_value + 1))
: ParseStep.InvalidString();
}),
},
PostSteps =
{
ConvertibleParseStep.Default, // Parses most .NET primitives and other types implementing IConvertible
},
};
var stringParser = builder.Build();
stringParser.Parse<bool?>("True"); // -> true
stringParser.Parse<UriKind>("RelativeOrAbsolute"); // -> UriKind.RelativeOrAbsolute
stringParser.Parse<ushort?>("0"); // -> 1
