codetainer/src/commands/list.js

A clean and simple CLI to manage and store code snippets with ease.

import chalk from "chalk";
import { loadSnippets } from "../utils/snippetStore.js";

export function registerListCommand(program) {
  program
    .command("list")
    .option("--tag <tag>", "Filter by tag")
    .option("--language <lang>", "Filter by language")
    .description("List saved snippets")
    .action((options) => {
      const snippets = loadSnippets();
      const entries = Object.entries(snippets);

      const filtered = entries.filter(([_, data]) => {
        const tagMatch = options.tag
          ? (data.tags || []).includes(options.tag)
          : true;
        const langMatch = options.language
          ? (data.language || "").toLowerCase() ===
            options.language.toLowerCase()
          : true;
        return tagMatch && langMatch;
      });

      if (filtered.length === 0) {
        console.log(chalk.yellow("No snippets found."));
        return;
      }

      filtered.forEach(([name, data], i) => {
        const tags = data.tags?.length ? ` [${data.tags.join(", ")}]` : "";
        const lang = data.language ? ` (${data.language})` : "";
        console.log(`${i + 1}. ${chalk.blue(name)}${lang}${tags}`);
      });
    });
