spacemod

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

# 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)
)

# 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.

# 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, 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
