helm-projectile-ag use thing-at-point as input?

Question

I want to use the current word as the input when I do helm-projectile-ag. That saves me the typing work. I didn't see this option in customize.

How would I implement that?

Answer 1

Found it. The setting is

(setq helm-ag-insert-at-point 'symbol)

Answer 2

IMHO, the helm-ag-insert-at-point is only applicable to helm-ag, not helm-projectile-ag.

I think you should use following elisp snippet: https://github.com/ageldama/configs/blob/master/emacs/dot-emacs-2018#L252

(defun my-helm-projectile-rg--region-selection (old-fn &rest arguments)
  (let ((thing (thing-at-point 'symbol)))
    (if (null thing)
        (apply old-fn arguments)
      thing)))

(advice-add #'helm-projectile-rg--region-selection
            :around #'my-helm-projectile-rg--region-selection)
