hop.el

An easymotion-like plugin highly inspired from hop.nvim.

Emacs Motion on Speed!
Move anywhere in your buffer with 1 or 2 keypress.

Why?

While there has been past options for jumping over the buffers like avy and ace-jump-mode, they both didn't fit me due to various reasons & limitations.

Hence, this package evolves.

Features

1. Single-Keypress Jumps for Targets Closer to the Cursor.
2. Convenient: Using single-keypress hop/jump as much as possible by generating hop sequence at runtime with TrieBackfilling Algorithm.
3. Flexible: Customizable alphabet splitting and jump location (start/middle/end of match).
4. Clear Distinction of Jumps based on required keypress (faces) and that can also be customized.
5. Easy Modification of Regex with Full PCRE Support for hop selection.
6. Default Exclusion of Subword Matches for simpler jump targets (matching words after hyphen is usually a distraction by having too many jump targets).
7. Last but not least, works across window splits.

I wouldn't say this is a feature, but in avy if you try to jump to p in abc p, then you'll only see 1 char due to buffer overflow, once you press that you'll see futher part of sequence, but this implementation automatically addresses that using 0 length overlay with 'before-string as necessary (as we reach \n or EOF).

Installation

It requires syohex/emacs-pcre, and pcre(-dev) package installed on your system at build time.

Install pcre(-dev) package based on your system

sudo xbps-install -y pcre-devel
sudo pacman --no-confirm pcre
# ...

Install the emacs package

If you're using elpaca/straight as package manager, write the following package declaration:

(use-package pcre
  ;; :straight if you use stright.el
  :ensure (pcre :host github :repo "syohex/emacs-pcre"
                  :pre-build ("make" "all")
                  :files (:default "pcre.el" "pcre-core.so")))
(use-package hop
  :ensure (hop :host github :repo "Animeshz/hop.el"))

Usage

The library exposes 5 interactive functions that can be accessed via M-x:

• hop-word
• hop-char
• hop-line
• hop-line-skip-whitespace
• hop-regex-pattern

Each of the function matches & create hops/jumps for their respective targets in the viewable buffer.

Package also exposes a few user-customizable variables, see the top of hop.el.
