neoformat

Supports over 70 filetypes with multiple external formatters like Prettier, Black, and gofmt, as detailed in the lengthy README list.

Uses getbufline() to format code directly from the buffer without requiring a file save, preserving unsaved changes.

Maintains marks, jumps, and undo history after formatting by using setline(), ensuring a seamless editing experience.

Allows defining multiple formatters per filetype and tries them sequentially until one succeeds, reducing formatting failures.
