# flymake-shellcheck (maintenance mode)

> **Note:** If you're using Emacs version 29 or higher, installing this package is not necessary, as the Flymake-Shellcheck integration is now built-in into the editor. This project is now in maintenance mode; no new features or enhancements will be made for it, unless they are required for security reasons.

An Emacs (26+) Flymake handler for bash/sh scripts, using [ShellCheck](https://github.com/koalaman/shellcheck). Installing Flymake is not necessary as it is included with Emacs itself.

## Installation

First, make sure ShellCheck is installed by following [the installation guide](https://github.com/koalaman/shellcheck#installing). After that, you can install `flymake-shellcheck` by using the `package-install` command (make sure [MELPA](https://melpa.org/) is included in your package sources):

M-x `package-install` RET `flymake-shellcheck` RET

Alternatively, you can just add `flymake-shellcheck.el` to your `load-path`.

## Usage

To enable the Flymake backend whenever a bash or sh script is visited, add the following to your `init.el` file:

```elisp

(add-hook 'sh-mode-hook 'flymake-shellcheck-load)

```

If you're using [`use-package`](https://github.com/jwiegley/use-package), try this instead:

```elisp

(use-package flymake-shellcheck

  :commands flymake-shellcheck-load

  :init

  (add-hook 'sh-mode-hook 'flymake-shellcheck-load))

```

After opening a shell/sh file, remember to enable Flymake:

M-x `flymake-mode` RET

## Customization

- You can set the `flymake-shellcheck-program` variable to the path of the ShellCheck executable in your system, in case `executable-find` wasn't able to find it automatically.

- You can set the `flymake-shellcheck-use-file` variable to `nil` if you wish to run the syntax checker on the contents of the buffer, rather than the contents of the file on disk (default: `t`).

- You can set the `flymake-shellcheck-allow-external-files` variable to `t` if you want to allow shellcheck to read external sources (it adds `-x` as argument, described in [the SC1091 docs](https://github.com/koalaman/shellcheck/wiki/SC1091), default: `nil`).
