[Smart case] For precise movements that further narrow possible jump locations

[volodymyrprokopyuk]

Hello,

I'd like to propose to change case insensitive search that highlights all possible jump locations to smart case search that has the following behavior:

• If the search string has only lowercase characters. perform case insensitive search (already implemented)
• If the search string contains uppercase characters, perform case sensitive search

Smart case search allows to be more precise in jumping around by further narrowing possible jump locations

What exactly do you mean by search? avy-goto-char-timer?

Because we have avy-case-fold-search for avy-goto-char.

Hello,

Yes, I mean the avy-goto-char-timer.

I have the below Avy configuration

(add-to-list 'load-path "~/.emacs.d/avy")
(require 'avy)
(global-set-key (kbd "M-j") 'avy-goto-char-timer)

How can I get smart case search described above for the avy-goto-char-timer case?

[abo-abo]

You should set:

(setq avy-case-fold-search nil)

avy-goto-char-timer calls avy--read-candidates, which will behave as you described when avy-case-fold-search is set to nil.

Hello,

Worked like a charm!

Thank you very much!

(setq avy-case-fold-search nil)

I should note though, the avy-case-fold-search documents a different behavior, it says setting it to nil makes it case-sensitive. Quote:

(defcustom avy-case-fold-search t
  "Non-nil if searches should ignore case."
  :type 'boolean)

Which btw is what I'm interested in: is there a way to make searches case-sensitive?

[Hi-Angel]

Although I stand corrected, the sentence "Non-nil if searches should ignore case." is vague, and can imply any behavior for nil value.
