Pretty Code String Builder

String builder wrapper that helps in generating pretty code. Supported features are:

• Indentation;
• Curly braces code blocks;
• Pragma warning directive;
• Nullable directive;
• Region directive.

All code blocks introduced using the builder will be automatically reverted to their original status using the IDisposable pattern.

Examples

Indent blocks

var builder = new PrettyCode.StringBuilder();
builder.AppendLine("def main():");
using (builder.Indent())
{
    builder.AppendLine("print('Hello world!')");
}

builder.AppendLine("# The function ended here!");
Console.WriteLine(builder.ToString());

Generated output:

def main():
   print('Hello world!')
# The function ended here!

Curly braces block

var builder = new PrettyCode.StringBuilder();
builder.AppendLine("struct cplusplus");
using (builder.CurlyBracesBlock(indent: false))
{
    builder.AppendLine("private:");
    builder.AppendLine("int foo;");
}

Console.WriteLine(builder.ToString());

Generated output:

struct cplusplus
{
private:
int foo;
}

Pragma warning directive

var builder = new PrettyCode.StringBuilder();
builder.AppendLine("try");
using (builder.CurlyBracesBlock())
{
    builder.AppendLine("/* Do something */");
}

builder.AppendLine("catch (Exception e)");
using (builder.PragmaWarningDirective("CA2200"))
using (builder.CurlyBracesBlock())
{
    builder.AppendLine("throw e;");
}

Console.WriteLine(builder.ToString());

Generated output:

try
{
   /* Do something */
}
catch (Exception e)
#pragma warning disable CA2200
{
   throw e;
}
#pragma warning restore CA2200

Nullable directive

var builder = new PrettyCode.StringBuilder();
using (builder.NullableDirective())
{
    builder.AppendLine("int? foo = null;");
}

Console.WriteLine(builder.ToString());

Generated output:

#nullable enable
int? foo = null;
#nullable restore

Region directive

var builder = new PrettyCode.StringBuilder();
using (builder.RegionDirective("My class"))
{
    builder.AppendLine("class MyClass { }");
}

Console.WriteLine(builder.ToString());

Generated output:

#region My class
class MyClass { }
#endregion // My class
