rifleman

An extendible dispatcher to lint/format code, based on rifle

This lets you run one command over lots of files/directories which could be in different languages - it classifies them by inspecting the mime type, extension, name or shebang, and then runs a command on those files.

This heavily simplifies and modifies the rifle config file format; including a condition to help check the 'shebang' value for scripts.

See config/format.conf for the default configuration file, I recommend you customize it to include the commands you use.

By default, I've included lots of the formaters/linters I use, an excerpt:

# html
ext x?html?, has prettier = prettier -w "$@"
# web technologies, handled by prettier
ext vue|yaml|json|graphql|tsx?|jsx?|s?css|less|md, has prettier = prettier -w "$@"

# golang
ext go, has go = go fmt "$@"

# python
ext py, has black = black "$@"
mime text/x-script.python, has black = black "$@"
shebang python(2|3)?, has black = black "$@"

# shell script
shebang zsh|bash, has shfmt = shfmt -w "$@"
shebang \/bin\/sh, has shfmt = shfmt -w "$@"
ext sh|(ba|z)sh, has shfmt = shfmt -w "$@"
mime text/x-shellscript, has shfmt = shfmt -w "$@"

Used emacs-format-all-the-code as reference.

Feel free to PR additional formatters!

Installation

To install with pip, run:

pip install rifleman

Usage

Usage: rifleman [-ljcah] [files]...

Options:
  -h, --help      show this help message and exit
  -l              list actions for files
  -j              list actions for files as JSON
  -c CONFIG_FILE  read config from specified file instead of default
  -a ACTION       name of configuration file in config directory to use
                  (format|lint)

This doesn't offer a way to discover/search for files, because so many tools already exist to do that.

For example, to run this against all files in a git-tracked directory:

rifleman $(git ls-files)

You can find (with the -exec flag), or the friendlier fd, to run against all files in the directory recursively:

fd -X rifleman

The -j and -l flags print what commands which would be used on each file instead of running the command.

The -c and -a files are used to determine which config file to use, completely altering the functionality of this.

By default, it uses the format.conf file in the ${XDG_CONFIG_HOME:-${HOME}/.config}/rifleman directory. -a is a shorthand; specifying -a lint looks for a file in the configuration directory called lint.conf

When this is first run, it will try to download the configuration files into the corresponding directories.
