fastmod

A fast partial replacement for the codemod tool, replace and replace all in the whole codebase. Regexes are matched by Rust regex crate. More information: https://github.com/facebookincubator/fastmod.

• Replace a regex pattern in all files of the current directory, ignoring files on .ignore and .gitignore:

fastmod regex_pattern replacement

• Replace a regex pattern in case-insensitive mode in specific files or directories:

fastmod --ignore-case regex_pattern replacement -- path/to/file path/to/directory …

• Replace a regex pattern in a specific directory in files filtered with a case-insensitive glob pattern:

fastmod regex replacement --dir path/to/directory --iglob '*/.{js,json}'

• Replace for an exact string in .js or JSON files:

fastmod --fixed-strings exact_string replacement --extensions json,js

• Replace for an exact string without prompt for a confirmation (disables regular expressions):

fastmod --accept-all --fixed-strings exact_string replacement

• Replace for an exact string without prompt for a confirmation, printing changed files:
