Discoverability

2022-03-14T19:13:42Z

JorgePeixoto: Which-key is on GNU ELPA

This page will try to list emacs' features and packages that help in auto discoverability. So if you don't know much about emacs' keybindings, commands, i.e., potential, you can have the information come to you and you just have to let you guide.

= Emacs builtins =

Emacs by default is built around this idea of discoverability. It is self-documented. See '''C-h ?'''.

It has helpful menus. You can make your way into [[org-mode]] or [[Dired]] with the menus.

== Ido - Interactively do things ==

[[ido]] gives interactivity to work with buffers and files. See also [[ivy]].

== Smex - extended M-x ==

[[Smex]] provides a convenient interface to your recently and most frequently used commands.

== Emacs 25 ==

Emacs 25 comes with even better introspection (see [http://www.wilfred.me.uk/blog/2016/02/20/coming-in-emacs-25-1-even-better-introspection/ this article]).

= Packages =

== Which-key (and guide-key) ==

You start a shortcut but you're unsure ? You want to know what are the other shortcuts available in the current major mode ? Or even global shortcuts ? You can discover all this with [https://github.com/justbur/emacs-which-key#additional-commands which-key].

Once you have installed it (it's in GNU [[ELPA]]), activate it with '''M-x which-key-mode''', start a keybinding (say "C-c") but don't finish it and wait for 1s (the default): now which-key will open a pop-up that lists all keybindings that follow "C-c".

This packages improves on [https://github.com/kai2nenobu/guide-key guide-key] in a few ways: It has pages to scroll through instead of taking up your whole screen, more options, and the ability to see all the "top-level" bindings.

However, it requires at least Emacs version 24.4, whereas guide-key is compatible with earlier versions.

[[File:which-key-bottom.png]]

== Helpful ==

[[Helpful]] is an alternative to the built-in Emacs help that provides much more contextual information.

[[File:Helpful.png]]

It is available in Melpa and Melpa Stable.

== Discover-my-major ==

This packages provides a function that does that: list all keybindings with their meaning for the current major mode. [https://github.com/steckerhalter/discover-my-major Discover-my-major] is in [[melpa]].

=== Discover.el ===

The latter builds on [https://github.com/mickeynp/discover.el discover.el], a work by Mickeynp (from [https://www.masteringemacs.org/article/discoverel-discover-emacs-context-menus the mastering emacs blog]), which is in turned based on and inspired by [[Magit]]'s great popup system. However, discover.el is a bit outdated (it didn't update with the improvements of Magit) and less featurefull than Hydras. But it's easy to use and to write your own discoverable commands too. See how it's used to help discover Dired, "search-forward" (C-s) or [https://github.com/zenozeng/yafolding.el#discover-commands-with-a-context-menu yafolding].

== Hydra ==

An [https://github.com/abo-abo/hydra/ Hydra] is a great package by abo-abo that "can be used to tie related commands into a family of short bindings with a common prefix - a Hydra."

You can pick hydras around (see the wiki on github). Some of them "just" group keybindings together, others provide a full list of a mode to help discoverability (for example, [https://github.com/abo-abo/hydra/wiki/Ibuffer the ibuffer Hydra] can be called immediately when we enter [[ibuffer]] mode and show all keybindings).

Hydras are also very easy to write. This is a simple one:

<source lang="lisp">
(defhydra hydra-zoom (global-map "<f2>")
"zoom"
("g" text-scale-increase "in")

== Hercules, joining which-key-mode and Hydras ==

[https://gitlab.com/jjzmajic/hercules.el Hercules] is a new mode that groups related commands, as with which-key-mode, and sequentially with no prefix keys, as with hydras, but it does that automatically. We don't have to copy hydras in our init files, they are created on the fly.

Prelude

2021-10-10T16:25:40Z

JorgePeixoto: Minor update (Prelude now requires Emacs 25.1+)

{{Package
|name=Emacs Prelude
|description=Advanced Emacs config
|author=[[User:Bozhidar|Bozhidar Batsov]]
|maintainer=[[User:Bozhidar|Bozhidar Batsov]]
|source=https://github.com/bbatsov/prelude
}}

'''Prelude''' has the goal to ease the initial Emacs setup process and to provide you with a much more powerful and productive experience than that you get out of the box. By using Emacs Prelude you're basically getting a "Get me out of the Prelude, I just want to use Emacs" card.

Emacs Prelude is compatible ONLY with GNU Emacs 25.1+. In general you're advised to always run Prelude with the latest stable Emacs release.

= Basic setup =

Assuming you're using an Unix-like OS (*BSD, GNU/Linux, OS X, Solaris, etc), you already have Emacs 25.1+ installed, as well as git & curl you can skip the whole manual and just type in your favorite shell the following command:

<syntaxhighlight lang="bash">
# curl -L https://github.com/bbatsov/prelude/raw/master/utils/installer.sh | sh
# You really should not be running commands from an anonymously editable wiki
</syntaxhighlight>

You can now power up your Emacs, sit back and enjoy Prelude.

= Helpful keybindings =

; {{Keys|C-c f}}
: Find a recently accessed file.

; {{Keys|C-c r}}
: Rename file and buffer.


= Common Customization =


You can tweak Prelude's config by adding '''.el''' files under the
'''personal''' directory. All files ending in ".el" will be read automatically when emacs starts up.

== Re-enable the arrow keys ==

Arrow keys for navigation are turned off by default. This is to get people to use the preferred Emacs defaults. To re-enable them, add the following to a file in your personal directory:

<syntaxhighlight lang="lisp">
(defun disable-guru-mode ()
(guru-mode -1)
)
(add-hook 'prelude-prog-mode-hook 'disable-guru-mode t)
</syntaxhighlight>

== Turn off whitespace mode ==

Prelude adds a lot of functionality from whitespace mode, including line-ending markers, highlighting of long-lines, space visualization. If you find these distracting, add the following to a file in your personal directory:

<syntaxhighlight lang="lisp">
(add-hook 'prog-mode-hook 'prelude-turn-off-whitespace t)
</syntaxhighlight>

== Change the default theme ==

Emacs Prelude uses the Zenburn theme by default, but you can easily
change this:

<syntaxhighlight lang="lisp">
(load-theme 'solarized-dark t)
</syntaxhighlight>



= [[GNU/Linux]] =




= [[OS X]] =




= [[Windows]] =

Note: on Windows 7 (Enterprise),

ln -s <prelude-directory> ~/emacs.d

did not work. But copying the content of prelude directory to .emacs.d worked as expected.

Note: it also expects git to be on the system paths defined in PATH. I used git from Cygwin. It worked.

On Windows XP - specifically for using clojure stuff, installing Prelude along the way:

NOTE: i had msysgit on my pc before I started this and I wouldn't be surprised if that put utilities in my path that made this all easier. But I didn't run cygwin or run inside bash or anything, I did it all from powershell and emacs.

You want to have git in your path
You want to have lein in your path
You want to have java in your path
You want to have clojure installed. A mystery to me - how does lein find clojure? I have clojure installed at c:\clojure, there's nothing in the path, things just worked when I went to run cider-jack-in, I don't know how clojure got located.

In emacs, do C-x shell, and if you can't run java -help, git, and lein, figure that out. Download the lein.bat file from leiningen.org, put it in a folder that is in your path, and run "lein self-install"

Once you have those prerequisite:

When you install prelude, you REPLACE your .emacs.d directory. IF you have anything you want in in init.el, or anything else in .emacs.d, rename the whole .emacs.d directory. It's going to be under /documents and settings/paul.footwarmer/.emacs.d, unless your name isn't paul.footwarmer. So rename .emacs.d or erase it. Then, in cmd or powershell, cd to /documents and settings/paul.footwarmer. Now run:

c:\prompt> git clone https://github.com/bbatsov/prelude.git .emacs.d

Now you will have a new .emacs.d. When you start emacs it will be prelude, grey theme, run a bunch of stuff, download a bunch of stuff.

Create a file in .emacs.d called "prelude-modules" and in it put (require 'prelude-clojure)

Restart emacs, see http://clojure-doc.org/articles/tutorials/emacs.html, try M-x cider-jack-in to see if you can run clojure from inside emacs. On my 8-year-old-laptop it takes about 30 seconds to start up.
