IniFileNet 0.2.0

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))))
{
	IniValueAcceptorOnlyLast url = new();
	IniValueAcceptorOnlyLast outputTemplate = new();
	IniValueAcceptorOnlyLast<bool> ask = new(Parse.Boolean);
	IniValueAcceptorOnlyLast<Regex?> regex = new((string value) =>
	{
		try
		{
			return new(new Regex(value), default);
		}
		catch (Exception ex)
		{
			return new(null, new IniError(IniErrorCode.ValueInvalid, string.Concat("Could not parse \"", value, "\" as Regex: ", ex.Message)));
		}
	});
	IniValueAcceptorOnlyLast<DateTimeOffset> latest = new((string value) => DateTimeOffset.TryParse(value, out var r)
		? new(r, default)
		: new(default, new(IniErrorCode.ValueInvalid, string.Concat("Could not parse \"", value, "\" as datetime"))));
	IniValueAcceptorMany<int, HashSet<int>> seen = new(Parse.Int32);
	IReadOnlyDictionary<string, IIniValueAcceptor> acceptors = new Dictionary<string, IIniValueAcceptor>()
	{
		["Url"] = url,
		["OutputTemplate"] = outputTemplate,
		["Ask"] = ask,
		["Regex"] = regex,
		["Latest"] = latest,
		["Seen"] = seen,
	};
	while (iniIn.TryReadNext(out var section))
	{
		IniError err = section.AcceptAll(acceptors);
		if (err.Code != default)
		{
			Console.WriteLine("Error reading ini file: " + err.Msg);
			throw err.ToException();
		}

		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);
	}
	if (iniIn.Reader.Error.Code != default)
	{
		Console.WriteLine("Error reading ini file: " + iniIn.Reader.Error.Msg);
		throw iniIn.Reader.Error.ToException();
	}
