Search Config

Modes​

There are 4 search modes, and only one of them can be chosen at any time.

1. Literal​

The default and the most commonly used search mode. In this mode, every characters are treated verbatim, a ( means a (, it does not mean the start of a capture group.

2. Regex​

This is powered by the Fancy Regex engine, where features such as look-around and backtracking are supported.

3. AST-Grep​

This is based on AST Grep, useful for structural search and replacement.

4. Naming Convention Agnostic​

Naming convention as in camelCase or snake_case, not upper-case or lower-case.

This is one of my favorite search modes, especially when dealing with business code.

In this mode, the search will be expanded to all different cases such as (non-exhaustive):

  1. kebab-case
  2. UPPER-KEBAB
  3. MACRO_CASE
  4. snake_case
  5. Title Case
  6. lower case
  7. UPPER CASE
  8. camelCase
  9. PascalCase

For example, searching hello world in this mode matches (non-exhaustive):

  1. helloWorld
  2. HELLO_WORLD
  3. HelloWorld

etc.

This is most powerful when used with Replace with Pattern.

Options​

Alongside modes, there are multiple options (not mutually exclusive) that can be turned on or off. These options are only applicable in Literal or Regex mode.

1. Match whole word​

When turned on, the search will be restricted to match word boundary (\b). For example, hello will not match itself in helloWorld, it will only match standalone hellos.

2. Case-sensitive​

When turned on, the uppercase or lowercase of each alphabet of the search becomes important. For example, hello will not match Hello.

3. Strict​

This is a shortcut for enabling both Case-sensitive and Match Whole Word.

4. Flexible​

This is a shortcut for disabling both Case-sensitive and Match Whole Word.

Globbing​

This only works in Global text search.
This is useful when you want to include/exclude certain files/directories during global search/replace.

This feature is powered by the globset library, which supports alternation such as:

  • *.{js,jsx}

Keybindings:

KeybindingAction
ISet include glob
ESet exclude glob

Replace All​

This is a global action that replaces all matches with the replacement pattern1.
