** Completion
|
||||
*** Minibuffer completion
|
||||
I use [[https://github.com/minad/vertico][vertico]] for my vertical/minibuffer completion. It's light, stays out of my way and works great out of the box, which is what I expect from all of my Emacs packages.

||||

** which-key
|
||||
I use [[https://github.com/justbur/emacs-which-key][which-key]], a small package that shows a window that describes available keybindings that follow the prefix I just hit. I just can't live without it, it's mandatory for me since I often don't remember which exact keybind I need to press to do a certain thing.

** expand-region
|
||||
[[https://github.com/magnars/expand-region.el][expand-region]] is a really useful package that allows for selection regions of text in semantic units. It works with text (words, sentences, paragraphs), code etc.

* Org mode
|
||||
This section contains all of my org mode configuration. Over the course of learning Emacs, I learned to appreciate org-mode more and more, and I use it for a lot of various tasks, from writing documents and exporting them to pdf, to writing this exact config, or just taking notes.
|

* Development
|
||||
This section contains all of my development related configuration. As a compsci student, it's absolutely mandatory for me to have a good editor experience and have it integrate well with all languages and frameworks I need to use in my day-to-day work.
|
||||
** git
|
||||
I use [[https://github.com/magit/magit][magit]] as my git client. It's incredible, it makes everything that you need to do in git available under a single prefix (C-x G), the diff interface is great and has genuinely made me more productive over the months of using it. Definitely prefer using it over the CLI.
