Trivial

Includes utilities and services for tasks, security, JSON, etc.

Tasks

using Trivial.Tasks;

Interceptor

Set an action with a specific interceptor to control its execution.

  • Interceptor.Debounce: Request to invoke a specific action several times in a short time but only the last one should be executed and previous ones should be ignored. A sample is real-time search suggestion.
  • Interceptor.Throttle: Raise actually only once in a short time even if invoke several times. A sample is the submit button in a form.
  • Interceptor.Times: The action can be only executed only when invoke in the specific times range and others will be ignored. A sample is double click.
  • Interceptor.Multiple: A handler to execute for the specific times and the state will be reset after a while.
// Set an action with interceptor.
var action = Interceptor.Debounce(() =>
{
    // Do something...
}, TimeSpan.FromMilliseconds(200));

// Invoke somewhere.
action();

Retry

Create a linear retry policy by LinearRetryPolicy or a customized one to process an action with the specific retry policy. And you can use ObservableTask to observe the state of an action processing.

Network

Contains the helper functions and extension functions for network, such as HTTP web client and its content.

using Trivial.Net;

Use JsonHttpClient to serialize the JSON format response with retry policy supports. And HttpUri for HTTP URI fields accessing.

Security

using Trivial.Security;

RSA

Convert a PEM (OpenSSL RSA key) or an XML string to the RSAParameters struct.

var parameters = RSAParametersConvert.Parse(pem);

And you can convert back by using the extension method ToPrivatePEMString or ToPublicPEMString. And the extension method ToXElement to XML.

Symmetric & Hash

Use a symmetric algorithm to encrypt and decrypt a string by calling SymmetricUtilities.Encrypt and SymmetricUtilities.DecryptText functions.

For hash algorithm, you can call HashUtilities.ToHashString function to get hash from a plain string and call HashUtilities.Verify to verify.

Access token

Provide a set of tools for OAuth including following models.

  • TokenInfo The access token and other properties.
  • AppAccessingKey The app identifier and secret key.
  • OAuthClient The token container with the ability to resolve the access token and create the JSON HTTP web client to access the resources required authentication.

Optional to implement the OAuthBasedClient base class to create your own business HTTP web client factory with OAuth supports.

JWT

Create a JSON web token to get the string encoded by initializing a new instance of the JsonWebToken class or the JsonWebTokenParser class.

var sign = HashSignatureProvider.CreateHS512("a secret string");
var jwt = new JsonWebToken<JsonWebTokenPayload>(new JsonWebTokenPayload
{
    Id = Guid.NewGuid().ToString("n"),
    Issuer = "example"
}, sign);

// Get authenticiation header value.
var header = jwt.ToAuthenticationHeaderValue();

// Parse.
var jwtSame = JsonWebToken<Model>.Parse(jwtStr, sign); // jwtSame.ToEncodedString() == header.Parameter

Secure string

Use the extension methods in the SecureStringExtensions class to convert the secret between SecureString and String/StringBuilder/Byte[].

And class RSASecretExchange is used to transfer the secret with RSA encryption.

Text

using Trivial.Text;

JSON

Includes writable JSON DOM JsonObjectNode and JsonArrayNode. And includes lots of useful converter like following.

  • JsonJavaScriptTicksConverter, and its fallback converters, to convert DateTime from/to JavaScript ticks number in JSON.
  • JsonUnixTimestampConverter, and its fallback converters, to convert DateTime from/to Unix timestamp number in JSON.
  • JsonNumberConverter and JsonNumberConverter.NumberStringConverter, to read number string in JSON.
  • JsonStringListConverter and its character separated converters (such as JsonStringListConverter.WhiteSpaceSeparatedConverter), to convert a string list from/to a string in JSON.

CSV

Read CSV or TSV file into a list of the specific models. For example, you have a model class CsvModel with string properties A and B, now you can map to the CSV file.

var csv = new CsvParser("abcd,efg\nhijk,lmn");
foreach (var model in csv.ConvertTo<CsvModel>(new[] { "A", "B" }))
{
    Console.WriteLine("{0},{1}", model.A, model.B);
}

Data

using Trivial.Data;

Cache

Save a number of model in memory cache by generic class DataCacheCollection.

Mathematics

using Trivial.Maths;

Arithmetic

There are a lot of arithmetic functions.

Arithmetic.IsPrime(2147483647); // True
Arithmetic.Gcd(192, 128); // 64

Numerals

Get the number symbols as you want. And get the numerals in English.

EnglishNumerals.Default.ToString(12345.67);
// twelve thousand three hundred and forty-five point six seven

EnglishNumerals.Default.ToApproximationString(1234567);
// 1.2M

And ChineseNumerals for Chinese and JapaneseNumerals for Japanese.

Angle and polar point

  • Angle Angle.
  • PolarPoint The point in polar coordinates.
  • SphericalPoint The point in spherical coordinates.

Set

  • NullableValueSimpleInterval<T> Interval, such as [20, 100).

Rectangular coordinates

  • OneDimensionalPoint The point in 1D (line) coordinates.
  • TwoDimensionalPoint The point in 2D (flat) coordinates.
  • ThreeDimensionalPoint The point in 3D (stereoscophic) coordinates.
  • FourDimensionalPoint The point in 4D (spacetime) coordinates.

Drawing

using Trivial.Drawing;

Color calculator

Color adjustment, converter, parser and mixer.

var color = ColorCalculator.Parse("rgb(226, 37, 0xA8)");
color = ColorCalculator.Opacity(color, 0.9);
color = ColorCalculator.Saturate(color, RelativeSaturationLevels.High);
color = ColorCalculator.Mix(ColorMixTypes.Lighten, color, Color.FromArgb(0, 240, 0));
