# 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` in all files of the current directory, ignoring files on `.ignore` and `.gitignore`:
|
|
|
|
`fastmod {{regex}} {{replacement}}`
|
|
|
|
- Replace a `regex` in case-insensitive mode in specific files or directories:
|
|
|
|
`fastmod --ignore-case {{regex}} {{replacement}} -- {{path/to/file_or_directory1 path/to/file_or_directory2 ...}}`
|
|
|
|
- Replace a `regex` 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 `regex`):
|
|
|
|
`fastmod --accept-all --fixed-strings {{exact_string}} {{replacement}}`
|
|
|
|
- Replace for an exact string without prompt for a confirmation, printing changed files:
|
|
|
|
`fastmod --accept-all --print-changed-files --fixed-strings {{exact_string}} {{replacement}}`
