This is a plugin for pre-commit that will run search and replace string operations against files to be committed. Note that this plugin operates on each line of a file therefore multiple line patterns are not supported.


By default, a YAML config file is loaded at .pre-commit-search-and-replace.yaml in the root of the repo. This config file should be a list of entries specifying any of the following keys:

  • search: (required) the string or regexp to search for. To use a regexp, start and end with slashes. e.g. /^mypattern/
  • replacement: the string to replace matched strings with. If specified, files will "fixed".
  • insensitive: boolean whether the regexp should be case-insensitive. default: false
  • extended: boolean whether the regexp should be extended. default: false
  • description: short text description of purpose of the entry.

The config file name can be changed by passing a --config PATH argument to the hook in the pre-commit config. A single search and replacement can be specified with --search STRING and --replacement STRING arguments as well instead of using a config file.

Example pre-commit config:

- repo:
  rev: v1.0.2
  - id: search-and-replace

Example search-and-replace config:

- search: /Something [bB]ad/
  replacement: Something Good
- search: foobar
  insensitive: true
  replacement: FOOBAR
- search: JustFailIfThisStringIsFound
