![]() ![]() You can read more in :h /magic.īasically Vim allows you to pass an option where certain characters are treated as literal characters while others as special characters. If you are acquainted with Vim regex, you might be aware of Vim's special "flavor" of Regex. Almost everything you see here is done using the search command / (I may release more guides in the future with different commands). I am going to limit the command to only the search command. It will show you how to use regex in Vim. Think of it as a regex guide that uses Vim. This is more of a regex guide than a Vim guide. There are other places where you can use regex, but based on my experience, these three are the main places I would use regex in.įinally, this is not a guide about how to use the global command, or grep, or whatever. The grep commands ( :vimgrep and :grep).The global and substitute command-line (ex) commands ( :g and :s).Many of Vim's search features allow you to use regular expressions. If you understand everything in this article, you should be well on your way to use regex in other environments. Although the syntax may vary slightly in different environments, the principle is the same. Many of the regex information you will be learning here is also transferable. But they are the ones that I find very useful. In fact, I'll be honest right now, that this article probably contains less than a third of what Vim regex can do. This article is by no means a complete regex tutorial. In this article, we will focus on learning and understanding regexes in Vim. You'll unlock more powerful commands using programs like sed, awk, grep, find, vim, and more. Third, it is fun (once you get to a certain proficiency). Many powerful programs (like parsers) are built on top of regexes. Regex allows you to search and modify texts efficiently. Programming is all about creating and updating text. Second, regex is powerful and knowing it can save you a lot of time. Regex knowledge in one domain will transfer everywhere. Sure, there are different regex flavors, but the basic principle is the same across all flavors. To a programmer, regex (regular expression) is a tool. Many desired to learn them but a few actually did. People who master them are hailed as gods. They are incredibly useful but also hard to read. ![]() It is not pleasant but it is good for your soul. Learning regular expressions is like learning latin.
