IniFileNet 0.3.0

IniFileNet

A .NET Library for reading and writing ini files.

Usage

Note that because this package is currently not at 1.0 yet, this may change. Below is some example code. I'll probably add a loader class that can load a file into memory in one chunk, and then allow one to essentially do dictionary lookups on it.

List<Target> targets = [];
using (IniStreamSectionReader iniIn = new(new IniStreamReader(new StreamReader(new FileStream(args[0], FileMode.Open, FileAccess.Read), Encoding.UTF8), new IniReaderOptions(ignoreComments: true))))
{
	IniValueAcceptorDictionaryBuilder b = new(new Dictionary<string, IIniValueAcceptor>(StringComparer.OrdinalIgnoreCase));
	IniValueAcceptorOnlyLast url = b.OnlyLast("Url");
	IniValueAcceptorOnlyFirst outputTemplate = b.OnlyFirst("OutputTemplate");
	IniValueAcceptorSingle<bool> ask = b.Single("Ask", Parse.Boolean);
	IniValueAcceptorOnlyLast<Regex?> regex = b.OnlyLast("Regex", (string value) =>
	{
		try
		{
			return new IniResult<Regex?>(new Regex(value), default);
		}
		catch (Exception ex)
		{
			return new IniResult<Regex?>(null, new IniError(IniErrorCode.ValueInvalid, string.Concat("Could not parse \"", value, "\" as Regex: ", ex.Message)));
		}
	});
	IniValueAcceptorOnlyLast<DateTimeOffset> latest = b.OnlyLast("Seen", (string value) => DateTimeOffset.TryParse(value, out var r)
		? new IniResult<DateTimeOffset>(r, default)
		: new IniResult<DateTimeOffset>(default, new(IniErrorCode.ValueInvalid, string.Concat("Could not parse \"", value, "\" as DateTimeOffset"))));
	IniValueAcceptorMany<int, HashSet<int>> seen = new(Parse.Int32);
	Dictionary<string, IIniValueAcceptor> acceptors = b.Acceptors;
	while (iniIn.NextSection())
	{
		ReadOnlyIniSection section = iniIn.Section;
		IniError err = section.AcceptAll(acceptors);
		// Can explicitly do it this way
		if (err.Code != default)
		{
			Console.WriteLine("Error reading ini file: " + err.Msg);
			throw err.ToException();
		}
		// Or just call this
		err.ThrowIfError();

		targets.Add(new Target
		(
			name: section.Name,
			url: url.Value ?? throw new IniException(IniErrorCode.ValueMissing, "Url is required for " + section.Name),
			outputTemplate: outputTemplate.Value ?? throw new IniException(IniErrorCode.ValueMissing, "OutputTemplate is required for " + section.Name),
			ask: ask.Value,
			regex: regex.Value,
			latest: latest.Value,
			seen: seen.Values
		));
		Util.ResetAll(acceptors.Values);
	}
	iniIn.Reader.Error.ThrowIfError();
}
