My neovim setup (with Ghostty)

Last year, I switched from Sublime Text to Neovim and Neovim has proved to be very efficient. This post showcases my Neovim setup and some useful tips. I agree with Guilherme D. Garcia that multiple tools for multiple purposes (RStudio for R, Sublime Text for markdown and $LaTeX$, etc.) is far from perfect, and Neovim indeed provided an integrated way of dealing with all these purposes (markdown/$LaTeX$, R, Python, and many more). It also provides the incredible capabilities of the Vim arsenal.

爲什麼是“喝西北風”

漢語裏人們常常說沒飯吃是“喝西北風”，例如詞典中常舉的吳敬梓《儒林外傳》第四十一回的：“都像你這一毛不拔，我們喝西北風。”那爲什麼是喝西北風，不是喝東南風、西南風呢？網上常見的說法是這跟我國的氣候地形有關。我國冬季吹西伯利亞南下的西北風，而這時正值冬天，如果沒有儲備，就只能忍飢挨餓，所以叫喝西北風。這種說法沒有依據，更何況漢語裏很少說冬天沒有糧食吃。說到沒有糧食，一般都是青黃不接，是指的春季莊稼剛剛播種，尚未長成，而舊穀已經吃完了。

Substitution in Vim with expressions

Substitution in vim is very efficient, especially with the help of expressions. This is especially useful for calculations. I discovered this usage when I wanted to insert a list of numbers to the beginning of each line. But before go to the example, let’s take a look at expressions in vim substitution. The expressions in vim are marked with “=”. This tells vim to treat the contents after “=” as expressions rather than literal texts. For example, vim will treat \=1+1 as 2 rather than the text 1+1. Using \=, I can insert numbers in the beginning of each line with expressions.
