Package: elpa-format-all (0.6.0-2)

Auto-format C, C , JS, Python, Ruby and 50 other languages

Lets you auto-format source code in many languages using the same command for all languages, instead of learning a different Emacs package and formatting command for each language.

Just do M-x format-all-buffer and it will try its best to do the right thing. To auto-format code on save, use the minor mode format-all-mode. Please see the documentation for that function for instructions.

You will need to install external programs to do the formatting. If `format-all-buffer` can't find the right program, it will try to tell you how to install it.

Many of the external formatters support configuration files in the source code directory to control their formatting. Please see the documentation for each formatter.

New external formatters can be added easily if they can read code from standard input and format it to standard output. Feel free to submit a pull request or ask for help in GitHub issues.
