How to Search in VS Code Faster Using Regex (With Examples)

posted 1 min read

Searching efficiently in VS Code can save you hours of manual work. While the default search is useful, regular expressions (regex) unlock powerful pattern-matching capabilities. In this guide, I'll break down essential regex patterns and show you how to use them in VS Code's search (Ctrl+F / Cmd+F).


Why Use Regex in VS Code?

  • Find complex patterns (emails, variables, broken links).
  • Refactor code faster (bulk rename, extract data).
  • Search across files (Ctrl+Shift+F / Cmd+Shift+F).

Essential Regex Patterns for VS Code

1. Basic Text Matching

  • hello → Matches exact word "hello".
  • h.llo → Matches "hallo", "hxllo" (. = any character).

2. Matching Multiple Characters

  • [aeiou] → Matches any vowel.
  • gr[ae]y → Finds "gray" or "grey".
  • [^aeiou] → Matches any character except vowels.

3. Quantifiers (How Many Times?)

  • a* → Matches 0 or more "a"s (e.g., "", "a", "aa").
  • a+ → Matches 1 or more "a"s (e.g., "a", "aa").
  • a{2,4} → Matches 2 to 4 "a"s (e.g., "aa", "aaa").

4. Word & Boundary Matching

  • \bword\b → Matches whole word "word" (not "keyword").
  • ^Hello → Matches "Hello" at the start of a line.
  • end$ → Matches "end" at the end of a line.

5. Groups & Capturing

  • (abc)+ → Matches "abc", "abcabc".
  • (img|src)=["'](.*?)["'] → Finds HTML image sources.

6. Lazy vs. Greedy Matching

  • ".*" → Greedy (matches entire "hello" and "world").
  • ".*?" → Lazy (matches "hello", "world" separately).

7. Special Characters

  • \d → Any digit (0-9).
  • \s → Whitespace (space, tab).
  • \w → Word character (a-z, A-Z, 0-9, _).

How to Use Regex in VS Code

  1. Open search (Ctrl+F / Cmd+F).
  2. Enable regex mode by clicking .* (or press Alt+R).
  3. Enter your pattern (e.g., \b\d{3}-\d{3}-\d{4}\b for phone numbers).
  4. Press Enter to see matches.

Pro Tip: Use Ctrl+Shift+F to search across files with regex!


Real-World Examples

Find all email addresses:

\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Z|a-z]{2,}\b
