The flymake-bashate Emacs package provides a Flymake backend for bashate, enabling real-time style checking for Bash shell scripts within Emacs.

(This package can also work with Flycheck: simply use the flymake-flycheck package, which allows any Emacs Flymake backend to function as a Flycheck checker.)

If this enhances your workflow, please show your support by ⭐ starring flymake-bashate.el on GitHub to help more Emacs users discover its benefits.

Installation

To install flymake-bashate from MELPA:

1. If you haven’t already done so, add MELPA repository to your Emacs configuration.

2. Add the following code to your Emacs init file to install flymake-bashate from MELPA:

   (use-package flymake-bashate
   :ensure t
   :commands flymake-bashate-setup
   :hook (((bash-ts-mode sh-mode) . flymake-bashate-setup)
         ((bash-ts-mode sh-mode) . flymake-mode))
   :custom
   (flymake-bashate-max-line-length 80))

Customizations

Ignoring Bashate errors

To make bashate ignore specific Bashate rules, such as E003 (ensure all indents are a multiple of 4 spaces) and E006 (check for lines longer than 79 columns), set the following variable:

(setq flymake-bashate-ignore "E003,E006")

(This corresponds to the -i or --ignore option in Bashate.)

Setting maximum line length

To define the maximum line length for Bashate to check:

(setq flymake-bashate-max-line-length 80)

(This corresponds to the --max-line-length option in Bashate.)

Specifying the Bashate executable

To change the path or filename of the Bashate executable:

(setq flymake-bashate-executable "/opt/different-directory/bin/bashate")

(Defaults to “bashate”.)
