SimpleTextTemplate

Build(.NET) NuGet Azure Artifacts

SimpleTextTemplateは、変数の埋め込みのみに対応したテキストテンプレートエンジンです。

説明

  • 文字列をUTF-8バイト列としてIBufferWriter<byte>に出力します。
  • {{ <変数>:<format>:<culture> }}で変数を埋め込みます。(formatcultureは省略可能)
  • {{}}内の先頭と末尾の空白(U+0020)は無視されます。
  • {{}}で囲まれた範囲以外の文字は、そのまま出力されます。

インストール

NuGet(正式リリース版)

dotnet add package SimpleTextTemplate.Generator

Azure Artifacts(開発用ビルド)

dotnet add package SimpleTextTemplate.Generator -s https://pkgs.dev.azure.com/finphie/Main/_packaging/DotNet/nuget/v3/index.json

使い方

次の例では、外部のライブラリであるCommunityToolkit.HighPerformanceを参照しています。

SimpleTextTemplate.Generator(推奨)

using System;
using System.Globalization;
using System.Text;
using CommunityToolkit.HighPerformance.Buffers;
using SimpleTextTemplate;

using var bufferWriter = new ArrayPoolBufferWriter<byte>();
var context = new SampleContext("Hello, World", 1000, new(2000, 1, 1, 0, 0, 0, TimeSpan.Zero));

var writer = TemplateWriter.Create(bufferWriter);
TemplateRenderer.Render(ref writer, "{{ DateTimeOffsetValue:o }}_{{ StringValue }}!", in context);
TemplateRenderer.Render(ref writer, "_{{ ConstantString }}_{{ ConstantInt:N3:ja-JP }}_{{ IntValue }}", in context, CultureInfo.InvariantCulture);
writer.Flush();

// 2000-01-01T00:00:00.0000000+00:00_Hello, World!_Hello_999.000_1000
Console.WriteLine(Encoding.UTF8.GetString(bufferWriter.WrittenSpan));

readonly record struct SampleContext(
    string StringValue,
    int IntValue,
    DateTimeOffset DateTimeOffsetValue)
{
    public const string ConstantString = "Hello";
    public const int ConstantInt = 999;
}

サンプルプロジェクト

生成コード
using System.Runtime.CompilerServices;
using CommunityToolkit.HighPerformance.Buffers;
using SimpleTextTemplate;

file static class Intercept
{
    [InterceptsLocation(1, "...")]
    public static void Write0(ref TemplateWriter<ArrayPoolBufferWriter<byte>> writer, string text, in SampleContext context, IFormatProvider? provider = null)
    {
        writer.WriteValue(Unsafe.AsRef(in context).@DateTimeOffsetValue, "o", CultureInfo.InvariantCulture);
        writer.WriteConstantLiteral("_"u8);
        writer.WriteString(Unsafe.AsRef(in context).@StringValue);
        writer.WriteConstantLiteral("!"u8);
    }

    [InterceptsLocation(1, "...")]
    public static void Write1(ref TemplateWriter<ArrayPoolBufferWriter<byte>> writer, string text, in SampleContext context, IFormatProvider? provider = null)
    {
        writer.WriteConstantLiteral("_Hello_999.000_"u8);
        writer.WriteValue(Unsafe.AsRef(in context).@IntValue, default, CultureInfo.InvariantCulture);
    }
}
