Delizious.Ini 1.20.0

Delizious Ini

What?

Delizious Ini is an easy to use .NET Standard library entirely written in C# for reading and writing of INI data.

New features in version 1.20.0

• Document available modes PropertyEnumerationMode, PropertyReadMode, PropertyWriteMode, SectionDeletionMode, PropertyDeletionMode, CommentReadMode and CommentWriteMode in README
• Improve readability of Features section in README

Features

Delizious Ini provides the following features:

• Intuitive API design applying Domain-driven design (DDD)
• Enumeration of sections
• Enumeration of properties
• Reading of a property
• Writing of a property
• Deletion of a section
• Deletion of a property
• Reading the comment of a section
• Reading the comment of a property
• Writing the comment of a section
• Writing the comment of a property
• Cloning an INI document
• Configurability
  • Failure behavior (e.g. throw a specific exception in case a section or property does not exist, or proceed with a fallback behavior) for almost every operation on instance and operation level
  • Case sensitivity that specifies how to treat section names and property keys
  • Invalid line behavior (Fail or Ignore)
  • Property's assignment separator and assignment spacer
  • Duplicate section behavior (Fail or Merge)
  • Duplicate property behavior (Fail, Ignore or Override)
  • Section's beginning and end delimiters
  • Regular expression pattern (regex) for section name
  • Newline string (Environment, Windows or Unix)
  • Comment string that indicates the beginning of a comment line

Upcoming features:

• Merge two INI documents

Quick start

const string ini = """
                   [Section]
                   Property=Current value
                   AnotherProperty=Another value

                   [EmptySection]
                   """;

using var textReader = new StringReader(ini);

// Use default configuration 
var configuration = IniDocumentConfiguration.Default
                                            .WithCaseSensitivity(CaseSensitivity.CaseSensitive); // Treat section names and property keys as case-sensitive (by default, case-insensitive)

var iniDocument = IniDocument.LoadFrom(textReader, configuration);

// Read existing property
var originalValue = iniDocument.ReadProperty("Section", "Property");
Console.WriteLine($@"Original property value: {originalValue}");

// Update existing property
iniDocument.WriteProperty("Section", "Property", "This is the new value");

var updatedValue = iniDocument.ReadProperty("Section", "Property");
Console.WriteLine($@"Updated property value: {updatedValue}");

// Write new property
iniDocument.WriteProperty("NewSection", "NewProperty", "NewValue");

// Delete section
iniDocument.DeleteSection("EmptySection");

// Delete property
iniDocument.DeleteProperty("Section", "AnotherProperty");

Console.WriteLine();
Console.WriteLine(@"INI document:");
iniDocument.SaveTo(Console.Out);
