# spacemod



`spacemod` is a text search-and-replace tool optimized towards refactoring

code.

```python

# example.py (before)

copy_file(to_file=to_file, from_file=from_file)

copy_file(

    to_file=get_file(filepath, mode),

    from_file=get_file_writer(other_filepath, other_mode)

)

```

```sh

# Use spacemod's custom pattern-matching language to deal with whitespace easier.

# Without -S, normal regex patterns are assumed.

$ spacemod -S \

  'copy_file ( to_file= (.*) , from_file= (.*) )' \

  'copy_file($2, $1)' \

  example.py

# spacemod will open interactive TUI and ask for approval of diffs. Use

# --accept-all to use spacemod non-interactively.

```

```python

# example.py (after)

copy_file(from_file, to_file)

copy_file(get_file_writer(other_filepath, other_mode)

, get_file(filepath, mode))

```

It is very similar to [fastmod](https://github.com/facebookincubator/fastmod),

but with some additional features:

* **Undo stack.** Approved a diff too soon? Hit `[u]ndo` to revert.

* **Yes to all diffs like this.** Auto-approve future diffs with the exact same content.

* **Parenthesis-matching (experimental).** Besides regex, spacemod also

  supports a custom regex-like language that requires less escaping and

  whitespace-handling.



## Installation

Check [the website](https://untitaker.github.io/spacemod/) for installation options.

## Matching Modes

By default, you use regexes to replace text. See [Matching

modes](./docs/matching.md) for the alternative modes that `spacemod` supports.

## Alternatives

There are many tools like `spacemod`, some of which may suit your needs better. Take a look at [Alternatives](./docs/alternatives.md).
