代码块样式测试：Go 与 Python 示例

这篇文章主要用来测试主题里的代码块。

要看的东西很简单：字体是不是清楚，缩进有没有乱，长行能不能横向滚动，亮色和暗色下语法高亮会不会刺眼。

Go example

先放一个简单的 HTTP 服务：

package main

import (
    "encoding/json"
    "log"
    "net/http"
    "time"
)

type Response struct {
    Message string    `json:"message"`
    Time    time.Time `json:"time"`
}

func main() {
    mux := http.NewServeMux()

    mux.HandleFunc("/health", func(w http.ResponseWriter, r *http.Request) {
        w.Header().Set("Content-Type", "application/json; charset=utf-8")
        json.NewEncoder(w).Encode(Response{
            Message: "ok",
            Time:    time.Now(),
        })
    })

    log.Println("server listening on :8080")
    if err := http.ListenAndServe(":8080", mux); err != nil {
        log.Fatal(err)
    }
}

再放一行比较长的代码，专门看窄屏时会不会撑破页面：

log.Printf("user=%s request_id=%s method=%s path=%s status=%d duration=%s", userID, requestID, r.Method, r.URL.Path, statusCode, time.Since(start))

Python example

再看一段 Python：

from __future__ import annotations

import json
from dataclasses import dataclass
from pathlib import Path
from statistics import mean


@dataclass
class Article:
    title: str
    words: int
    tags: list[str]


def load_articles(path: Path) -> list[Article]:
    data = json.loads(path.read_text(encoding="utf-8"))
    return [Article(**item) for item in data]


def summarize(articles: list[Article]) -> dict[str, object]:
    total_words = sum(article.words for article in articles)
    all_tags = sorted({tag for article in articles for tag in article.tags})

    return {
        "count": len(articles),
        "total_words": total_words,
        "average_words": round(mean(article.words for article in articles), 2),
        "tags": all_tags,
    }


if __name__ == "__main__":
    articles = load_articles(Path("articles.json"))
    print(json.dumps(summarize(articles), ensure_ascii=False, indent=2))

最后放一段 Shell，看看普通命令块的效果：

cd /data/myblog
hugo --buildDrafts --gc --minify
