前两天在 B 站看了一个视频， 介绍了目前国内 AI 领域做得非常不错的一家公司，也是量化界的领头羊-幻方。其中，谈到他们开发大模型 deepseek 已经拥有非常强劲的实力，能够满足大部分场景下的 AGI 使用，比如机器人、自动化代码生成器等。联想到之前我在网上看到 avante.nvim 这个插件可以为 nvim 带来 AI 辅助功能，当时由于国内还无法使用国外开发的大模型工具，所以就不了了之了。现在终于可以在国内合理合法的使用 AI 在 nvim 中辅助编程了。

购买 API 服务

第一个步骤是需要购买 API 服务，然后获取 key，这样我们就可以在 nvim 中调用密钥发送请求了。

得到密钥后，需要设置环境变量

##=============================================================================[deepseek: openai]
## https://platform.deepseek.com/api_keys: sk-******************************a7c
export OPENAI_API_KEY=sk-******************************a7c
##=============================================================================

avante.nvim

avante 提供了接入多个大模型应用 API 的配置，比如 openai、claude，而 deepseek 为了跟 openai 保持一致接口，也是采用了 openai 的方式。因此我们看到上面配置的密钥格式是 openai 的格式。

配置

由于我使用的是 markview 这款插件来渲染 markdown，因此就没有使用上面注释部分中的 render-markdown。

操作

我一开始犯了一个迷糊：avante 写的是使用 <leader>aa 启动对话。我以为这里的 leader 就是我自己设置的 leader 键位，即 ;。但是后来发现 avante 配置的 leader 其实对应的应该是 Space 空格键，所以如果启动对话，需要敲击的键位是：<Space>aa。

效果

最近在测试升级 glibc，其中有一个测试条件需要过滤：针对 nss 的一个条件判断，我们不需要添加测试，否则 glibc 无法通过编译。其中使用的语法就是 bash 的正则表达式，但是混合了特殊符号。即使对于一个非常熟悉 bash 语法的程序员，在处理正则表达式时也常常感到心累，大概是因为其复杂的语法。

比如这里（代码位于 glibc-2.30/scripts/test-installation.pl）

if ($name ne "nss_ldap" && $name ne "db1"
    && $name ne "thread_db"
    && $name ne "nss_test1" && $name ne "libgcc_s") {
    $link_libs .= " -l$name";
    $versions{$name} = $version;
}

我们想使用 sed 添加一个条件， && $name ne "nss_test2"。一开始我尝试自己去写正则表达式，但是两次都失败了，得不到想要的结果。于是想到让 AI 试试看，便把上面那段代码粘贴到一个临时的脚本文件，然后简单描述了我需要得到的效果，至于怎么处理，就交给 AI 了。

1

use `sed` to add one more condition: $name ne "nss_test2"

让我十分震惊的是，AI 竟然很快就给出了答案，而且还详细说明分析的思路，并且把运行的结果也展示出来。

use sed to add one more condition: $name ne “nss_test2”

I’ll provide a sed command that will add the new condition while preserving the existing formatting. Here’s the sed command to run:

1

sed -i '/&& $name ne "nss_test1" && $name ne "libgcc_s"/s/&& $name ne "libgcc_s"/\&\& $name ne "nss_test2" \&\& $name ne "libgcc_s"/' test.sh

This command:

  1. Looks for the specific line containing both “nss_test1” and “libgcc_s” conditions
  2. Replaces just the “libgcc_s” condition part with “nss_test2” followed by the original “libgcc_s” condition
  3. Maintains proper spacing and formatting
  4. Uses -i flag to edit the file in-place

After running this command, the line will become:

1

        && $name ne "nss_test1" && $name ne "nss_test2" && $name ne "libgcc_s") {

一个bug

不过对于生产的代码，我们还是需要进行判断，因为 AI 也是有可能出错的，而且还一本正经的给出解释。

比如下面的一个代码块，我需要去掉一个判断(glibc-2.30/sysdeps/posix/shm-directory.h)

  /* Validate the filename.  */                                               \
  if (namelen == 1 || namelen >= NAME_MAX || strchr (name, '/') != NULL)      \
    {                                                                         \
      __set_errno (errno_for_invalid);                                        \
      return retval_for_invalid;                                              \
    }                                                                         \

这个是 glibc 自 2.21 版本开始使用的 shm_open 命令，用于验证文件名称是否合法。但是这个对于带有子目录路径的文件名（如 spdm/spdx_param），直接给出了一个错误的判断。这个 bug 需要把该判断去掉，重新编译 glibc。

我尝试让 AI 做这个事情，尝试了几次都没有得到结果，但是 AI 自我解释里竟然说可以得到结果，真的有点绷不住。所以对于生产环境的代码，我们一定要人工检查之后再允许上线。

  3. Uses -i flag to edit the file in-place

After running this command, the line will become:

it dit not work

Let me provide a more precise sed command that will work for your specific case. Based on the context you’ve shown, here’s the correct sed command:

1

sed -i '/if (namelen == 1 \|\| namelen >= NAME_MAX \|\| strchr (name, .\/.) != NULL)/s/ *\|\| *strchr (name, .\/.) != NULL//' test.sh

This command will:

  1. Match the exact line containing all three conditions
  2. Remove only the strchr (name, '/') != NULL part and its preceding || operator
  3. Preserve the backslash continuation and proper spacing
  4. Edit the file in-place with -i flag

After running this command, the specific line will change from:

1

if (namelen == 1 || namelen >= NAME_MAX || strchr (name, '/') != NULL)      \

To:

1

if (namelen == 1 || namelen >= NAME_MAX)      \

The rest of the file, including the error handling block below it, will remain unchanged. Let me know if you need any clarification or if you’d like me to explain any part of the sed command in more detail.

this is a c++ macro, you need to be precise

You’re right - since this is a C++ macro, we need to be very precise with the formatting and spacing. Let me provide the exact sed command that will work for this specific case:

1

sed -i '/if (namelen == 1 \|\| namelen >= NAME_MAX \|\| strchr (name, .\/.) != NULL)/s/ *\|\| *strchr (name, .\/.) != NULL//' test.sh

This command will:

  1. Match the exact macro line with all three conditions
  2. Remove only the strchr (name, '/') != NULL part and its preceding || operator
  3. Preserve the exact spacing and backslash continuation
  4. Edit the file in-place with -i flag

After running this command, the macro will change from:

1

if (namelen == 1 || namelen >= NAME_MAX || strchr (name, '/') != NULL)      \

To:

1

if (namelen == 1 || namelen >= NAME_MAX)      \

The rest of the macro definition, including the error handling block below it, will remain unchanged with the exact same formatting. The command preserves:

  • The exact spacing before and after the conditions
  • The backslash continuation
  • The indentation of the following lines
  • The macro structure

Let me know if you need any clarification or if you’d like me to explain any part of the sed command in more detail.

i think the correct answer is: sed -i ’s/|| *strchr (name, ./.) != NULL//g'

You’re absolutely correct! That is indeed the simpler and more precise sed command for this case. Let me explain why your solution is better:

1

sed -i 's/|| *strchr (name, .\/.) != NULL//g' test.sh

This command:

  1. Uses a simpler pattern that just matches the specific condition we want to remove
  2. Handles the spaces correctly with * after ||
  3. Uses \/ to escape the forward slash in the pattern
  4. Uses g flag to ensure it works even if the pattern appears multiple times
  5. Preserves all other formatting exactly

Your solution is better because:

  • It’s more concise
  • It doesn’t need to match the entire line
  • It will work regardless of what comes before the condition
  • It preserves all spacing and formatting perfectly

After running your command, the macro will change from:

1

if (namelen == 1 || namelen >= NAME_MAX || strchr (name, '/') != NULL)      \

To:

1

if (namelen == 1 || namelen >= NAME_MAX)      \

And the rest of the file will remain completely unchanged. Thank you for pointing this out - your solution is indeed the better approach!

Avante markdown 无法高亮

参考：bug: Codeblocks and quote blocks have weird interactions

需要修改 ~/.config/nvim/lua/plugins/nvim-treesitter.lua，通过 config 使其加载进来

config = function(_, opts)
    require'nvim-treesitter.configs'.setup(opts)
end
