jamescherti/pathaction.el: Emacs: Execute pathaction.yaml rules using pathaction

Execute pathaction.yaml rules using the pathaction command-line tool.

(The pathaction command-line tool enables the execution of specific commands on targeted files or directories. Its key advantage lies in its flexibility, allowing users to handle various types of files simply by passing the file or directory as an argument to the pathaction tool. The tool uses a .pathaction.yaml rule-set file to determine which command to execute. Additionally, Jinja2 templating can be employed in the rule-set file to further customize the commands.)

• The pathaction command-line tool.

To install pathaction with straight.el:

1. It if hasn't already been done, add the straight.el bootstrap code to your init file.
2. Add the following code to the Emacs init file:

(use-package pathaction
  :ensure t
  :straight (pathaction
             :type git
             :host github
             :repo "jamescherti/pathaction.el")
  :config
  (add-to-list 'display-buffer-alist '("\\*pathaction:"
                                       (display-buffer-at-bottom)
                                       (window-height . 0.33))))

To install pathaction with use-package and :vc (Emacs >= 30):

(use-package pathaction
  :ensure t
  :vc (:url "https://github.com/jamescherti/pathaction.el"
       :rev :newest)
  :config
  (add-to-list 'display-buffer-alist '("\\*pathaction:"
                                         (display-buffer-at-bottom)
                                         (window-height . 0.33))))

To execute the pathaction action that is tagged with main, you can call the following Emacs function:

• pathaction-run: This is the main function for triggering pathaction actions.
• "main": This is the tag used to identify a specific action. The tag you provide to the function determines which set of actions will be executed. In this case, "main" refers to the actions that are specifically tagged with this name.

To edit the pathaction.yaml file, use the following function, which will prompt you to select one of the pathaction.yaml files in the parent directories:

To configure pathaction to open its window under the current one, you can use the display-buffer-alist variable to customize how the pathaction buffer is displayed. Specifically, you can use the display-buffer-at-bottom action, which will display the buffer in a new window at the bottom of the current frame.

Here's the code to do this:

(add-to-list 'display-buffer-alist '("\\*pathaction:"
                                     (display-buffer-at-bottom)
                                     (window-height . 0.33)))

• pathaction-before-run-hook: This hook is executed by pathaction-run before the pathaction command is executed. By default, it calls the save-some-buffers function to prompt saving any modified buffers:

  (setq pathaction-before-run-hook '(save-some-buffers))

• pathaction-after-create-buffer-hook: This hook is executed after the pathaction buffer is created. It runs from within the pathaction buffer, enabling further customization or actions once the buffer is available.

By default, pathaction-before-run-hook only calls a function to save the current buffer before executing actions or commands that affect the current or any other edited buffer.

To make pathaction save all buffers, use the following configuration:

(defun my-save-some-buffers ()
  "Prevent `save-some-buffers' from prompting by passing 1 to it."
  (save-some-buffers))

(add-hook 'pathaction-before-run-hook #'my-save-some-buffers)

(If you want to prevent save-some-buffers from prompting the user before saving, replace (save-some-buffers) with (save-some-buffers t).)
