Synctex 文件何时写入？

syncTeX 文件是什么时候写入的？在写入之后，有没有办法将回调传入 lua？我希望在编译过程结束时读取它，而不必编译两次才能获取它。

我可以运行外部脚本或包装编译过程来完成此任务，但这比必要的工作要多得多。

finish_pdffile 发生在 synctex 写入之前，因此它不好 ;/

这是所有回调的列表，我相信，我没有看到任何有帮助的东西。

local callbacktypes = callbacktypes or {
  find_read_file     = exclusive,
  find_write_file    = exclusive,
  find_font_file     = data,
  find_output_file   = data,
  find_format_file   = data,
  find_vf_file       = data,

  find_sfd_file      = data,
  find_pk_file       = data,
  find_data_file     = data,
  find_opentype_file = data,
  find_truetype_file = data,

  read_sfd_file      = exclusive,
  read_pk_file       = exclusive,
  read_data_file     = exclusive,
  read_truetype_file = exclusive,
  read_type1_file    = exclusive,

  pre_dump             = simple,
  start_run            = simple,
  stop_run             = simple,
  start_page_number    = simple,
  stop_page_number     = simple,
  show_error_hook      = simple,
  show_warning_message = simple,
  show_error_message   = simple,
  show_lua_error_hook  = simple,
  start_file           = simple,
  stop_file            = simple,
  finish_pdffile = data,
  finish_pdfpage = data,
  define_font = exclusive,
}

我也不确定纯 lua 方式或是否在所有 lua 代码完成后写入 synctex 文件。

答案1

从源代码来看，synctex 文件在所有回调之后被关闭。

    /* Close {\sl Sync\TeX} file and write status */
    synctexterminate(log_opened_global);       /* Let the {\sl Sync\TeX} controller close its files. */
    free_text_codes();
    free_math_codes();
    if (log_opened_global) {
        wlog_cr();
        selector = selector - 2;
        if ((selector == term_only) && (callback_id == 0)) {
            tprint_nl("Transcript written on ");
            tprint_file_name(NULL, texmf_log_name, NULL);
            print_char('.');
            print_ln();
        }
        lua_a_close_out(log_file);
    }
}

这是结束close_files_and_terminate，之后唯一调用的是do_final_end();设置错误状态并停止。

因此我认为 synctex 数据在当前运行期间无法可靠地获得。
