在 libgit2 中执行 git 描述

Question

我想像 "git describe" 在终端中那样工作。

如何获取我的存储库的当前标签？现在我的程序正在打印

09B8A518

每次尝试时，这个数字都不一样，所以我认为它不是提交 ID 左右。

当我在终端执行 "git describe" 时，输出是 "v0.1.2"

有办法吗？

顺便问一下，如何将 "git_describe_result *out;" 转换为字符串？

    string path = C://my/local/repo;
    string result;
    git_libgit2_init();

    const char * REPO_PATH = path.c_str();
    git_repository * repo = nullptr;
    git_repository_open(&repo, REPO_PATH);

    git_describe_result *out;
    git_describe_options opts = GIT_DESCRIBE_OPTIONS_INIT;
    opts.version = GIT_DESCRIBE_FORMAT_OPTIONS_VERSION;  // GIT_DESCRIBE_OPTIONS_VERSION;

    git_describe_workdir(&out, repo, &opts);
    cout << out << endl;

    git_describe_result_free(out);
    git_repository_free(repo);
    git_libgit2_shutdown();

Answer 1

将git_describe_result转换为git_describe_format的字符串。

Answer 2

现在这对我有用

            string path = C://my/local/repo;
            string result;
            git_libgit2_init();

            const char * REPO_PATH = path.c_str();
            git_repository * repo = nullptr;
            git_repository_open(&repo, REPO_PATH);
            git_describe_result *out;
            git_describe_options opts = GIT_DESCRIBE_OPTIONS_INIT;
 // ---------------------------------------
            // I added this
            opts.describe_strategy = GIT_DESCRIBE_ALL;
            opts.max_candidates_tags = 0;
            opts.only_follow_first_parent = 1;
 // ---------------------------------------
            git_describe_workdir(&out, repo, &opts);

    // --------------------------------------

    // and also this
                git_buf out1 = { 0 };
                const git_describe_format_options opts1=GIT_DESCRIBE_FORMAT_OPTIONS_INIT;
                git_describe_format(&out1, out, &opts1);
                result = out1.ptr;
                cout << result << endl;

    // ---------------------------------------
            git_describe_result_free(out);
            git_repository_free(repo);
            git_libgit2_shutdown();
