V2ex 是一个程序员聚集的论坛，也是我经常访问的一个论坛，经常有人在论坛上提问技术问题。前两天遇到一个帖子，问的是 vscode 如何取消按下点以后自动补全第一个候选项。

After updating Hugo to the latest version (v 0.62), apart from the issue of missing HTML code, I have also observed that level 1 header written in Markdown is not rendered in the generated table of contents (TOC).

从开始完全使用 Neovim 进行日常代码开发与文档编写到现在，已经过去了大约一年半的时间，一年半以前，我对 Vim 的了解还处在非常初级的阶段，经过长时间的使用与学习，已经达到了熟练使用的程度。当然，Vim 的知识过于庞大，即便我已经使用了一年半的时间，还有很多 Vim/Neovim 的特性或者知识仍然有待了解与发掘。

在使用 Neovim 的过程中，我对 Neovim 和 Vim 的历史以及它们之间的恩怨情仇也产生了兴趣，散布在互联网上各处的博客、视频以及论坛讨论让我对过去的历史有了一定了解。

最近在使用 Hugo 生成博客文章的时候，发现有一篇新写的文章无法生成，而其他博文都可以成功渲染，非常奇怪。

2019 年年末的这三个月过得很快，最近一个月都在紧张忙碌中度过，以至于错过了年末的时间，没有写一篇 2019 年的阅读总结。

In this post, I want to share how to do number arithmetic quickly and get what you want in specified format. More specifically, the topic is:

How do we add, subtract, multiply or divide a value to each number in a range?

Vim-snippet provides a lot of useful Ultisnips snippets for various filetypes. For example, for Markdown, to insert level 1 header, the snippet trigger is sec, and for level 2 and 3 header, the triggers are ssec and sssec respectively. These triggers are non-intuitive and hard to remember and type.

Introduction

Last year, I have written a post on how to edit texts inside the browser using Vim/Nvim or browser extensions which have Vim emulations. But none of them is satisfactory enough since they are either not convenient to use or lacking features compared to real Neovim empowered by various plugins.

Due to Markdown's inablity to center and resize image properly, I use the raw HTML tags inside markdown file to include images:

<p align="center">
<img src="xxx.xx.xx/test.jpg">
</p>

Introduction

I write my blog posts in Markdown and build the blog using Hugo. Hugo supports front matter for Markdown so that you can attach some metadata for a post, such as title, date, tags, categories, etc.

labelme 是一款常用的计算机视觉任务标注工具，可以用来标注分类，检测，分割等任务的数据。对于检测任务，labelme 生层的标注文件是 json 格式，每个图像对应一个相应的 json 文件。但是很多任务都使用 PASCAL VOC 的 xml 格式标注，例如maskrcnn-benchmark 任务中的 voc 数据集。

This post continues my previous post on nifty Nvim/Vim techniques.

几周之前，在 YouTube 上看到了 Vim 创始人 Bram Moolenaar 在 Vim Conf 2018 上的主题报告，介绍了 Vim 的历史以及可能要添加的一些新特性，萌生了给这个视频配字幕的想法。

Introduction

When I am writing some prototyping code inside Neovim, I want to run the script without going to the terminal and typing python toy_script.py. Of course, we can use :!python % in the command line to run the script (see :h :!). The problem is that running external command will block Nvim/Vim, and we can not move the cursor until the script finishes running.

Sometimes, when you are working with your local changes, you may want to pull the latest updates from the remote Git repository. You can use git stash to store the unfinished work temporarily.

The system I am currently using has Anaconda pre-installed by root under system locations.

Just a few days ago, the builtin Language Server Protocol support has been merged into Neovim master.

This post is a hands-on experience of setting up LSP support for Python with the python-language-server.

Previously, I have talked about how to convert PDF to images uing pdftoppm in this post. In this post, I want to share how to accomplish this task with Imagemagick.

上 Reddit 或者 GitHub 时，在讨论中，经常会碰到一些缩略语，作为一名非 native speaker，经常有点摸不着头脑，不知道这些缩略语啥意思，这篇文章总结一些常用缩略语以及中文含义。

There are several options related to backup in Vim/Nvim.
