How to enter regular expressions for matching in vscode

How to enter a regular expression in vscode for matching:

Use the shortcut key "Ctrl F" to bring up the search box

Examples of matching methods using regular expressions:

1) . — Matches any character

dot symbol . Used to match any character:

b.t

The above regular match matches "bot", `"bat" and any three-character word starting with b and ending with t. But if you want to search for the dot symbol, you need to escape it with \ , so the following regex only matches the exact text "b.t":

b\.t

2) .* — means match anything

Here . means "any character", * means "this symbol repeats the previous content any number of times." Put them together (.*) means "any symbol repeated any number of times." For example, you can use it to find matches that start or end with some text. Suppose we have a javascript method like this:

loadScript(scriptName: string, pathToFile: string)

We want to find all calls to this method where pathToFile points to the folder "lua ” in any file. The following regular expression can be used:

loadScript.*lua

This means, "match all strings that start with "loadScript" and end with "lua"."
