 ```sh
 git clone https://github.com/binary-husky/chatgpt_academic.git
 cd chatgpt_academic
 ```
 
-我们建议将`config.py`复制为`config_private.py`并将后者用作个性化配置文件以避免`config.py`中的变更影响你的使用或不小心将包含你的OpenAI API KEY的`config.py`提交至本项目。

+1. 如果你在国内，需要设置海外代理才能够顺利使用 OpenAI API，设置方法请仔细阅读config.py（1.修改其中的USE_PROXY为True; 2.按照说明修改其中的proxies）。
 2. 配置 OpenAI API KEY。你需要在 OpenAI 官网上注册并获取 API KEY。一旦你拿到了 API KEY，在 config.py 文件里配置好即可。

-## 使用WSL2（Windows Subsystem for Linux 子系统）
-选择这种方式默认您已经具备一定基本知识，因此不再赘述多余步骤。如果不是这样，您可以从[这里](https://learn.microsoft.com/zh-cn/windows/wsl/about)或GPT处获取更多关于子系统的信息。
-
-WSL2可以配置使用Windows侧的代理上网，前置步骤可以参考[这里](https://www.cnblogs.com/tuilk/p/16287472.html)
-由于Windows相对WSL2的IP会发生变化，我们需要每次启动前先获取这个IP来保证顺利访问，将config.py中设置proxies的部分更改为如下代码：
-```python
-import subprocess
-cmd_get_ip = 'grep -oP  "(\d+\.)+(\d+)" /etc/resolv.conf'
-ip_proxy = subprocess.run(
-        cmd_get_ip, stdout=subprocess.PIPE, stderr=subprocess.PIPE, text=True, shell=True
-        ).stdout.strip() # 获取windows的IP
-proxies = { "http": ip_proxy + ":51837", "https": ip_proxy + ":51837", } # 请自行修改
-```
-在启动main.py后，可以在windows浏览器中访问服务。至此测试、使用与上面其他方法无异。

+// jpge.cpp - C++ class for JPEG compression.
+// Public domain, Rich Geldreich <richgel99@gmail.com>
+// v1.01, Dec. 18, 2010 - Initial release
+// v1.02, Apr. 6, 2011 - Removed 2x2 ordered dither in H2V1 chroma subsampling method load_block_16_8_8(). (The rounding factor was 2, when it should have been 1. Either way, it wasn't helping.)
+// v1.03, Apr. 16, 2011 - Added support for optimized Huffman code tables, optimized dynamic memory allocation down to only 1 alloc.
+//                        Also from Alex Evans: Added RGBA support, linear memory allocator (no longer needed in v1.03).
+// v1.04, May. 19, 2012: Forgot to set m_pFile ptr to NULL in cfile_stream::close(). Thanks to Owen Kaluza for reporting this bug.
+//                       Code tweaks to fix VS2008 static code analysis warnings (all looked harmless).
+//                       Code review revealed method load_block_16_8_8() (used for the non-default H2V1 sampling mode to downsample chroma) somehow didn't get the rounding factor fix from v1.02.

-## [0/10] 程序摘要: check_proxy.py
-
-这个程序是一个用来检查代理服务器是否有效的 Python 程序代码。程序文件名为 check_proxy.py。其中定义了一个函数 check_proxy，该函数接收一个代理配置信息 proxies，使用 requests 库向一个代理服务器发送请求，获取该代理的所在地信息并返回。如果请求超时或者异常，该函数将返回一个代理无效的结果。
-
-程序代码分为两个部分，首先是 check_proxy 函数的定义部分，其次是程序文件的入口部分，在该部分代码中，程序从 config_private.py 文件或者 config.py 文件中加载代理配置信息，然后调用 check_proxy 函数来检测代理服务器是否有效。如果配置文件 config_private.py 存在，则会加载其中的代理配置信息，否则会从 config.py 文件中读取。
-
-## [1/10] 程序摘要: config.py
-
-本程序文件名为config.py，主要功能是存储应用所需的常量和配置信息。

+## [18/22] 程序概述: crazy_functions\生成函数注释.py
+
+该程序文件名为./crazy_functions\生成函数注释.py。该文件包含两个函数，分别为`生成函数注释`和`批量生成函数注释`。
+
+函数`生成函数注释`包含参数`file_manifest`、`project_folder`、`top_p`、`temperature`、`chatbot`、`history`和`systemPromptTxt`。其中，`file_manifest`为一个包含待处理文件路径的列表，`project_folder`表示项目文件夹路径，`top_p`和`temperature`是GPT模型参数，`chatbot`为与用户交互的聊天机器人，`history`记录聊天机器人与用户的历史记录，`systemPromptTxt`为聊天机器人发送信息前的提示语。`生成函数注释`通过读取文件内容，并调用GPT模型对文件中的所有函数生成注释，最后使用markdown表格输出结果。函数中还包含一些条件判断和计时器，以及调用其他自定义模块的函数。
+
+函数`批量生成函数注释`包含参数`txt`、`top_p`、`temperature`、`chatbot`、`history`、`systemPromptTxt`和`WEB_PORT`。其中，`txt`表示用户输入的项目文件夹路径，其他参数含义与`生成函数注释`中相同。`批量生成函数注释`主要是通过解析项目文件夹，获取所有待处理文件的路径，并调用函数`生成函数注释`对每个文件进行处理，最终生成注释表格输出给用户。
+
+## [19/22] 程序概述: crazy_functions\解析项目源代码.py
+
+该程序文件包含了多个函数，用于解析不同类型的项目，如Python项目、C项目、Java项目等。其中，最核心的函��是`解析源代码()`，它会对给定的一组文件进行分析，并返回对应的结果。具体流程如下：
+
+1. 遍历所有待分析的文件，对每个文件进行如下处理：
+
+   1.1 从文件中读取代码内容，构造成一个字符串。
+
+   1.2 构造一条GPT请求，向`predict_no_ui_but_counting_down()`函数发送请求，等待GPT回复。
+
+   1.3 将GPT回复添加到机器人会话列表中，更新历史记录。
+
+   1.4 如果不是快速调试模式，则等待2秒钟，继续分析下一个文件。
+
+2. 如果所有文件都分析完成，则向机器人会话列表中添加一条新消息，提示用户整个分析过程已经结束。
+
+3. 返回机器人会话列表和历史记录。
+
+除此之外，该程序文件还定义了若干个函数，用于针对不同类型的项目进行解析。这些函数会按照不同的方式调用`解析源代码()`函数。例如，对于Python项目，只需要分析.py文件；对于C项目，需要同时分析.h和.cpp文件等。每个函数中都会首先根据给定的项目路径读取相应的文件，然后调用`解析源代码()`函数进行分析。
+
+## [20/22] 程序概述: crazy_functions\读文章写摘要.py
+
+该程序文件为一个名为“读文章写摘要”的Python函数，用于解析项目文件夹中的.tex文件，并使用GPT模型生成文章的中英文摘要。函数使用了request_llm.bridge_chatgpt和toolbox模块中的函数，并包含两个子函数：解析Paper和CatchException。函数参数包括txt，top_p，temperature，chatbot，history，systemPromptTxt和WEB_PORT。执行过程中函数首先清空历史，然后根据项目文件夹中的.tex文件列表，对每个文件调用解析Paper函数生成中文摘要，最后根据所有文件的中文摘要，调用GPT模型生成英文摘要。函数运行过程中会将结果写入文件并返回聊天机器人和历史记录。
+
+## [21/22] 程序概述: crazy_functions\高级功能函数模板.py
+
+该程序文件为一个高级功能函数模板，文件名为"./crazy_functions\高级功能函数模板.py"。
+
+该文件导入了两个模块，分别是"request_llm.bridge_chatgpt"和"toolbox"。其中"request_llm.bridge_chatgpt"模块包含了一个函数"predict_no_ui_long_connection"，该函数用于请求GPT模型进行对话生成。"toolbox"模块包含了三个函数，分别是"catchException"、"report_exception"和"write_results_to_file"函数，这三个函数主要用于异常处理和日志记录等。
+
+该文件定义了一个名为"高阶功能模板函数"的函数，并通过"decorator"装饰器将该函数装饰为一个异常处理函数，可以处理函数执行过程中出现的错误。该函数的作用是生成历史事件查询的问题，并向用户询问历史中哪些事件发生在指定日期，并索要相关图片。在查询完所有日期后，该函数返回所有历史事件及其相关图片的列表。其中，该函数的输入参数包括：
+
+1. txt: 一个字符串，表示当前消息的文本内容。
+2. top_p: 一个浮点数，表示GPT模型生成文本时的"top_p"参数。
+3. temperature: 一个浮点数，表示GPT模型生成文本时的"temperature"参数。
+4. chatbot: 一个列表，表示当前对话的记录列表。
+5. history: 一个列表，表示当前对话的历史记录列表。
+6. systemPromptTxt: 一个字符串，表示当前对话的系统提示信息。
+7. WEB_PORT: 一个整数，表示当前应用程序的WEB端口号。
+
+该函数在执行过程中，会先清空历史记录，以免输入溢出。然后，它会循环5次，生成5个历史事件查询的问题，并向用户请求输入相关信息。每次询问不携带之前的询问历史。在生成每个问题时，该函数会向"chatbot"列表中添加一条消息记录，并设置该记录的初始状态为"[Local Message] waiting gpt response."。然后，该函数会调用"predict_no_ui_long_connection"函数向GPT模型请求生成一段文本，并将生成的文本作为回答。如果请求过程中出现异常，该函数会忽略异常。最后，该函数将问题和回答添加到"chatbot"列表和"history"列表中，并将"chatbot"和"history"列表作为函数的返回值返回。
