Nore Emacs

Quick start

It works on Emacs version 22.1.1+ , provides more reasonable styles: more organized code, more consistent, more cleaner and more faster. You can run it on any environment Emacs itself runs on: GUI or Terminal, even you can run multiple Emacs instances with different version on the same machine at the same time.

clone Nore Emacs from github

git clone --depth=1 https://github.com/junjiemars/.emacs.d.git ~/.emacs.d

open Emacs, after Emacs compile all elisp files, then reopen Emacs
want more functionalities see Recipe section

Additionally, it is important to remind you to take care as it is exceptionally fast.

Story

Emacs is the most powerful editor in the world there is no one of. It’s programmable, elegant and self-documenting.

As my daily work increasingly revolves around Emacs, I realize it’s time to integrate Emacs into my very being - not just for opening, navigating, editing, and saving files. Inspired by Euclid’s approach to geometry, I have created Nore Emacs.

Nore Emacs aims to provide a seamless experience with its focus on consistency, speed, stability, and hackability. It ensures consistent behavior across all platforms where Emacs is supported.

Organization

Now, let’s begin at Level Two. The key thing to remember is to familiarize yourself with some basic Elisp. You can start by using the Emacs built-in help system (C-h i m Elisp) and navigate to the Elisp documentation.

Principles

Adaptive: Nore Emacs is designed to run on any operating system, whether it’s a graphical or terminal interface. It is compatible with both the latest Emacs versions and even older ones. Furthermore, you can use a single Emacs configuration for multiple coexisting Emacs instances on the same machine
Consistent: Regardless of the environment or time, Nore Emacs always maintains consistent behavior. You can rely on a seamless experience no matter where or when you use it.
Minimalism: Nore Emacs promotes a minimalist approach, both internally and externally. It only loads the necessary components based on your specific needs, ensuring efficiency and avoiding unnecessary clutter.

Requirements

Emacs [22.1,29.1]
Keyboard+

Where

Linux, whatever GUI or TUI
Darwin, whatever GUI or TUI
Windows, whatever GUI or TUI
Raspberry Pi and Docker container, etc.,
Network or without Network
One machine, multiple Emacs instances

What

You are the master of your Emacs, …
Navigating, finding, grepping in the same way wherever, …
Org Mode that’s your new life, …
Amazing programming experiments, C, Lisp, …
It’s a no-cost extension and git friendly infrastructure.

Install

Just one thing you need to do, clone it (just <1024KiB) to your HOME directory:

git clone --depth=1 https://github.com/junjiemars/.emacs.d.git ~/.emacs.d

First run Nore Emacs, it should automatically do:

byte/native compile elisp source files.
install packages, if you allow it.

After first run Nore Emacs, exit and then reopen Emacs.

On Windows, if you’d Git-Bash installed but no Emacs, you are lucky, a one line code will do it all for you and more: fix some Emacs’ issue for you, and you don’t need run src_shell{git clone …},

instead,

HAS_EMACS=1 bash <(curl https://raw.githubusercontent.com/junjiemars/kit/master/win/install-win-kits.sh)

Now, it will works perfectly, but if you want to more control and more features, such as themes, packages, and fonts etc., see next section: recipe

Organization

Signify your Emacs HOME as (emacs-home*).

Your private configuration directory at (emacs-home* "private/"). All things under it you can rename, move, delete.

All Elisp files should be compiled, if you meet some trouble, a magic interactive function (clean-compiled-files) should help, run it and reopen the Emacs.

Naming

Introduce the rules of naming files and functions.

Core Files Naming: single word and simple name.

:port the port of socks proxy server
:server the address of socks proxy server
:version socks version
:allowed t enabled, nil disabled

If :allowed t, url-gateway-method should be switch to socks when Emacs initializing. After Emacs initialization, you can toggle-socks! and no matter :allowed is t or nil.

Network Utils

Emacs comes with a lots of wrappers(net-utils.el) around the common network utilities. Such as M-x ping a host. But net-utils.el has some inconveniences:

If you want to ping with options you must set ping-program-options customizable variable.
IPv6 supporting: on Unix-like OS there are individual program for IPv6, such as ping6, but on Windows OS just one ping program and with -6 option.

commands around net-utils, and named those commands with * prefix. Using C-u M-x *<command> you can set the options for that <command>.

The following interactive commands had been defined for Emacs22.1+ whatever OS you using:

M-x *arp
M-x *dig
M-x *ifconfig
M-x *ping
M-x *traceroute

Browser

toggle external or internal browser: M-x toggle-browser!
lookup web for symbol, word, etc.,: M-s w
lookup online dictionaries: M-s d

Package

It’s file-oriented, you can find more simpler and faster way to implement almost functionalities that use-pacakge does and more.

(*self-env-spec*
 :put :module
 (list :remove-unused nil
       :package-check-signature 'allow-unsigned
       :allowed t))

:remove-unused whether remove the unused packages that be defined in def-self-package-spec
:package-check-signature nil does not check signature when installing packages.
:allowed t enabled, nil disabled

The user defined package spec locate in (*self-mod-spec*).

File

Using dired as a File Manager is awesome, same experiences on Windows, Darwin and Linux.

ls Program

For Windows, there are no built-in ls program, but you can install GNU’s ls via Git-Bash.

For Darwin, let dired don’t do stupid things.

screenshots:

ido-dired

find Program

On Windows, if GNU’s find has already in your disk, and let Windows stupid find or findstr program go away. Don’t setq find-program on Windows, because dired can not differ the cases between local and remote.

Now, on Windows you can use M-x find-dired or M-x find-name-dired

screenshots:

compress Program

On Windows, there are no builtin zip/unzip program, but Emacs ship with minizip program. Although minizip without recursive functionalities, but do some tricks with minizip, we can zip files and directories with minizip, even export org to odt OpenDocument. And more 7-Zip standalone command version also be supported.

On Windows, there are logical bugs in dired-aux.el, We can not using Z key compress or uncompress file to or from .gz or .7z. The good news: if gunzip or 7za installed we can do it now.

You can using c in dired mode compress to *.gz, *.7z or *.zip. For some ancient Emacs24-, ! zip x.zip ? to zip.

It’s headache when default-file-name-coding-system not equal with locale-coding-system specifically on Windows. Even view archived file in arc-mode, will display wrong encoded file names.

On Windows, there are some encoding issues when default-file-name-coding-system not equal locale-coding-system.

display non-unicode encoded directory name or file name;
insert non-unicode encoded directory;
compress the files with with locale-coding-system filenames;
dired-do-shell-command or dired-do-async-shell-command;

The good news is the whole above issues had gone in this kit.

For .rar archive, emacs really sucks.

on Emacs 23.3.1, using unrar-free in archive-rar-summarize function, but on Emacs 26.1 using lsar, and those all had been hard coded in arc-mode.el.
7z l output is not compatible with lsar and unrar.

Editing

Scratch

New a scratch buffer or switch to the existing one.

Mark

Provides the abilities to mark symbol, filename and line in current buffer then you can M-w the marked part.

Using mark-sexp@ default mark whole Lisp sexp or C block at point. If prefix N is non nil, then forward or backward to sexps boundary, just like the builtin mark-sexp does.

mark-quoted@ mark whole quoted things at point and do not care whatever the mode is.

mark-word@ default mark the whole word at point. If prefix N is non nil, then forward or backword to word boundary, just like the builtin mark-word does.

mark-defun@ more stable in variant programming modes than `mark-defun’.

Clipboard

In terminal, Emacs can not copy to or paste from system clipboard when on Darwin or Linux. For such cases, we need external programs to help us do the job. Now, Nore Emacs integrates this functionalities, so we can use natural keys (such as C-w, C-y) to copy to or paste from system clipboard.

iSearch

There are no uniformed isearch functionalites among in isearch-forward, isearch-backward and isearch-forward-symbol-at-point. Now, in Nore Emacs those functionalites unified to two functions: isearch-forward* and isearch-backward*.

In Nore Emacs, by default, isearch-forward* and isearch-backward* same with the built-in ones. Except we can search the text of activated region. C-s and C-r will search forward or backward just like vi’s * does. And more, searching word, quoted string, or filename forward or backword.

Open line

Emulates vi’s o and O command in Emacs, the built-in one open-line or split-line do not indent accordingly the current line. See Open Next Line.

C-o open-next-line
C-M-o open-previous-line

Comment

comment-line has stupid behaviors, that why toggle-comment had been made.

toggle-comment: C-x C-;

Kill

kill-word@ and kill-sexp@ are frequently editing commands when programming.

Keys

Obey the defaults of Emacs’ keymap.

Programming

Generic editing

Just introduce Nore Emacs’ improvements.

Lisp programming

Lisp programming in Emacs already good enough, if ParEdit installed editing Lisp code more easy.

slime is the best tool for Common Lisp programming.

For Scheme programming, there are builtin minor modes: gambit-mode for Gambit Scheme system, and chez-mode for Chez Scheme system.

REPL

*slime-repl*: M-x slime
*gambit*: M-x run-gambit
*chez*: M-x run-chez

C programming

Now, we are in the cycle of editing, compiling, debugging.

screenshots:

Editing

Change C programming style using C-c .. And there is a new elegant and practical style: cc*-style-nginx.

View C system include

Like vi’s gf command, you can using C-c f i to open C system include file on local or remote in view-mode and via M-, to go back. It supports gcc, clang, and msvc.

On Darwin, you can find correct include path in Man-mode now.

Macro expand

Mark the code that include a macro call then C-c C-e, you should see the expansion of the macro in *Macro Expanded*, whatever you are using gcc, clang and msvc, locally or remotely.

screenshots:

macro expansion for msvc

Dump predefined macros

Dump compiler predefined macros, C-c #, you should see the predefined macros in *Macros Predefined*, whatever you are using gcc and clang locally or remotely.

screenshots:

dump predefined macros for clang

Compiling

Press M-x compile then:

Unix-like:
- raw: cc c.c -oa.out

I. M-x clean-compiled-files then exit and reopen Emacs.

II. Check Emacs configurations:
- M: system-configuration-options
- M: system-configuration-features
- M: features
- M: load-history
then do I.

III. Check *Compilation-Log* buffer, then do I.
IV. Check (*self-paths*), then do I.
V. Disable the problematic item in (*self-env-spec*), then do I.
VI. Disable the problematic item in (*self-mod-spec*), then do I.
