Using Regular Expression With Visual Studio Code Replace Functionnality

That’s a great example to use Regex in the Find and Replace function of Visual Studio Code.

To replace all occurrences of [n] with [^n] in Visual Studio Code, where n is any number, follow these steps:

Step 1. Open the Find and Replace Panel

• Press Ctrl + H (Windows/Linux) or Cmd + Option + F (Mac).

Step 2. Enable Regular Expression Search

• Click the .* icon (or press Alt + R) to enable regex mode.

Step 3. Enter the Find Pattern

• Use the following regular expression to match [n] where n is a number:

  1

  \[(\d+)\]

  Copy
  • $$ and $$ match the literal square brackets.
  • (\d+) captures one or more digits.

Step 4. Enter the Replace Pattern

• Use this replacement string:

  1

  [^$1]

  Copy
  • $1 refers to the captured number inside the brackets[3].

5. Replace All

• Click “Replace All” (or press Alt + Enter to select all matches, then Ctrl + Shift + L to replace).

Example

This will convert every [number] into [^number] throughout your document using Visual Studio Code’s regex-powered find and replace.

Note: Make sure regex mode is enabled, or the patterns won’t work as intended.
