Neo emacs is a configuration framework for GNU Emacs which is based on doom emacs and focuses on the java web application coding environment. Neo emacs has the following features:
- Code completion: Lsp-java supports maven and gradle project.
- Program debugging: Dap-java supports program debugging.
- Http client: Rest-client is a tool to manually explore and test HTTP REST webservices just like Postman.
- Http client*: verb a package for Emacs which allows you to organize and send HTTP requests.
- SQL client: Ejc-sql turns Emacs into a simple SQL client which supports various databases.
- Redis client: IRedis is a terminal client for redis with auto-completion and syntax highlighting.
- Terminal emulator: Emacs-libvterm (vterm) is fully-fledged terminal emulator inside GNU Emacs based on libvterm.
- Knowledge management system: Org-roam borrows principles from the Zettelkasten method, providing a solution for non-hierarchical note-taking.
Most of the time, for safety you should install emacs by brew or complie it from source ,that will give you a better compatibility.
In other words, try not to install emacs throuht Free installation package like Gnu Emacs below.
There have many emacs distribution,just choose one and install it.
-
EmacsPorts is the best choice to run NeoEmcas on macos now.
brew tap railwaycat/emacsmacport brew install emacs-mac --with-natural-title-bar --with-mac-metal \ --with-librsvg --with-starter --with-emacs-big-sur-icon --with-native-comp \ defaults write org.gnu.Emacs TransparentTitleBar DARK \ defaults write org.gnu.Emacs HideDocumentIcon kES -
Emacs-plus which I used for a long time once.
brew tap d12frosted/emacs-plus brew install emacs-mac --with-natural-title-bar \ --with-mac-metal --with-librsvg --with-starter \ --with-emacs-big-sur-icon -- -
Gnu-Emacs is the official emacs client which I used for windows platform.
-
Source Code Building form source which I use rarely.
building emacs with with source code1 git clone git://git.savannah.gnu.org/emacs.git 2 cd emacs 3 git checkout emacs-28 4 brew install libxml2 5 make configure 6 ./configure --with-native-compilation --with-modern-papirus-icon --with-no-titlebar 7 make -j4 8 make install 9 open nextstep/Emacs.app
After emacs installation, set environment variables which names EMACS ,this depends on your emacs exec path.
export EMACS=/Applications/Emacs.app/Contents/MacOS/Emacs
clone doom-emacs and neo-emacs from github.
git clone --depth 1 https://github.com/doomemacs/doomemacs ~/.emacs.d
git clone --depth 1 https://github.com/vanniuner/neo-emacs.git ~/.doom.d/
Set up a vpn if you need it.
export http_proxy="ip:port"
export https_proxy="ip:port"
Set your emacs cmd for doom install.
export EMACS= $YOUR EMACS CMD PATH$
Make sure there have Cmake lib or install it.
-
Ubuntu
sudo apt install cmake sudo apt install libtool-bin -
MacOs
brew install cmake libtool gnuplot d2 ripgrep fzf terrastruct/tap/tala graphviz
At last run below, this will take few minutes. And it depends on the quality of your network.
~/.emacs.doom/bin/doom install
~/.emacs.doom/bin/doom.cmd install
brew upgrade
brew update && brew upgrade emacs-mac && brew cleanup emacs-mac
export EMACS=/Applications/Emacs.app/Contents/MacOS/EMACS
sh ~/.emacs.d/bin/doom upgrade
sh ~/.emacs.d/bin/doom install
sh ~/.emacs.d/bin/doom sync
It offer a window transparent solution which could transparent background but the font not.Note after install the patch, here have a alternative package to control the transparent value.
(use-package transwin
:config
(setq transwin-delta-alpha 5)
(setq transwin-parameter-alpha 'alpha-background)
:bind
("C-M-=" . transwin-inc)
("C-M--" . transwin-dec)
("C-M-0" . transwin-toggle))
The awesome patch could make cursor more funny.But there have a bug,If you shift to full screen from a window state , there will remain a shadow of the current cursor which will stay here forever.I will make cursor in replace mode before shifting to full screen.This might makes it effect less more.
Here have a tutorial to apply patch if you are using emacs plus.
-
Put the patches file under to `/opt/homebrew/Library/Taps/d12frosted/homebrew-emacs-plus/patches/emacs-30`
-
Modify `/opt/homebrew/Library/Taps/d12frosted/homebrew-emacs-plus/Formula/emacs-plus@30.rb`, around local_patch.

Just install emacs plus, you could use `brew reinstall`
Customize your private setting config in the config.el ; use setq
Before start up,install fonts in the <./neoemacs/font> directory firstly.
Cause different platform have different font name,after font installed there need a adjustment based on the fact.

You’d better install vterm in a terminal environment case there might have error incompatible architecture.
Vterm is not available on windows.
Thus windows user have to use eshell as a downgrade plan.
-
Install vterm
You’d better install vterm in a terminal environment case there might have error incompatible architecture.
If vterm complie failed in emacs, we could complie it manually.cd .emacs.d/.local/straight/build/vterm/ mkdir -p build # install cmake and libtool-bin brew install cmake libtool mkdir -p build cd build cmake .. make -
Fish shell optimize
If you are using fish shell ,fortunately there have some optimize config prepared for you.
-
feature:
-
use fish shell on emacs vterm.
-
use command `ff` %anyfile% on vterm will open %anyfile% in a new emacs buffer.It’s very useful.
if [ "$INSIDE_EMACS" = 'vterm' ] function clear vterm_printf "51;Evterm-clear-scrollback"; tput clear; end end function vterm_cmd --description 'Run an Emacs command among the ones been defined in vterm-eval-cmds.' set -l vterm_elisp () for arg in $argv set -a vterm_elisp (printf '"%s" ' (string replace -a -r '([\\\\"])' '\\\\\\\\$1' $arg)) end vterm_printf '51;E'(string join '' $vterm_elisp) end function ff set -q argv[1]; or set argv[1] "." vterm_cmd find-file (realpath "$argv") end

http proxy
In fact there have two different config ,first one for vterm and another for emacs inner plugins.
In vterm the http proxy be effected by `~/.config/fish/config.fish`,you could config it like this.set -x http_proxy http://vpn.local.com:10887 set -x https_proxy http://vpn.local.com:10887 set -x no_proxy ".aliyun.com,192.168.0.0/16,137.239.155.184"When you are using emacs lisp program such as restclient, you could config proxy like this.
The difference is wildcard(defun convert-to-regex (str) (let* ((joined (replace-regexp-in-string "," "\\\\|" str)) (wrapped (concat "^\\(" joined "\\)"))) wrapped)) (setq url-proxy-services `(("http" ."vpn.local.com:10887") ("https" ."vpn.local.com:10887") ("no_proxy" . ,(convert-to-regex ".*aliyun.com,192.168.0.0/16,137.239.155.184")))) -

The privacy configuration
In here you could save any connections in your setting config.
But where should the setting located especially for our Emacs config project with a public github repository? There have a privacy path which is excluded in the public repository named user-private-dir, You could config your connection’s account/password here for safely.
There default load a db-work module which having your privacy config .(add-to-list 'load-path user-private-dir ) (use-package! db-work ) -
Config your particular db connection
(use-package ejc-sql :commands ejc-sql-mode ejc-connect :config (setq clomacs-httpd-default-port 18090) (ejc-create-connection "connection-name" :classpath "~/.m2/repository/mysql/mysql-connector-java/8.0.17/ mysql-connector-java-8.0.17.jar" :connection-uri "jdbc:mysql://localhost/user?useSSL=false&user=root&password=pwd" :separator "</?\.*>" ) ) (provide 'db-work) -
Write Sql file
Before try to use ejc sql, firstly create a sql file which named with a suffix .sql, cause emacs will turn on the sql minor mode so that ejc-sql could works well. And then useSPC e cto connect a particular database which you have configurated. Emacs will popup a minibuffer listing candidates which show you the connection-name.
Secondarily, write your testing sql content which surrounded by a tag, cause we have configurated :separator by a syntax meaning tag in order to execute a single sql rather than to choose it.For sure you could make any comment with the tag’s schema.
Further more, you could use delimiter sign for batch execution. the delimiter could customization by any character.
Finnaly, useC-c C-cto execute it. It’s just execute the content which surrounded by a tag in your cusor.1 <SELECT name='select all org'> 2 SELECT * FROM TABLE_ORG 3 </SELECT> 4 5 <SELECT> 6 delimiter ; 7 COMMENT ON COLUMN TABLE_ORG.PROJECT_CODE IS '项目编码'; 8 COMMENT ON COLUMN TABLE_ORG.PERIOD IS '期间'; 9 </SELECT> -

Emacs Rime which makes to embedding an input method be possible whthin the emacs.Emacs could benefit form the flexible configuration of rime.
On macos it’s required to install Squirrel which is one of rime’s distribution. Squirrel is installed in your os system as a input method.
Note that the configuration of rime located at home/Library/Rime/. We want to sharing this configuration between Eamcs rime and os rime.
So there have a variable which named rime-user-data-dir , And another important variable is rime-librime-root which configed the librime location.
| variable | required |
| rime-user-data-dir | true |
| rime-librime-root | true |

No need to sent images files of the source.
The embedded base64 image make to distribute your html documentation more easily. -
Optimize Line Number
Just hidden the colon after line number character.
Modify `~/.emacs.d/.local/straight/repos/org/lisp/ox-html.el`.1 (let* ((code-lines (split-string code "\n")) 2 (code-length (length code-lines)) 3 (num-fmt 4 (and num-start 5 (format "%%%ds " 6 (format "%(add-hook 'code-review-mode-hook 7 (lambda () 8 ;; include *Code-Review* buffer into current workspace 9 (persp-add-buffer (current-buffer))))%%ds: " -
Image Directory
Cause org mode html export program need a image directory locate at org root directory.
Highly recommended:
Uselnmaking an mirror of the directory.
Make the image directory as your screenshot file’s saving location.ln -s ~/org/org-roam/image any_where/image
Restclient provide a test suite for HTTP REST in Emacs.The official repository here restclient.el.
Yea, a pretty old old project.Fortunately doom emacs have integrated it.We just need open it with (rest +jq).
+jq makes restclient have the ability to parse a particular response which Content-Type equalable application/json.
The amazing feature is restclient support set variables or make a part of response being a variables which one could as a request part for another HTTP REST.
Here we take the value from results as a variables which named count.
GET https://www.zhihu.com/api/v3/oauth/sms/supported_countries
-> jq-set-var :count .count
Only jq-set-var could works when the content-type equal to application/json MIME type
Fortunately we have solution for other mime type, it’s restclient-set-var, you could use elisp to parse the response;
GET https://www.baidu.com/sugrec
-> run-hook (restclient-set-var ":queryid" (cdr (assq 'queryid (json-read))))
Content-Type: application/x-www-form-urlencoded; charset=utf-8
About the variables infomation in current buffer, we could use C-c Tab to show them.
Verb is a new package for http client,becase the restclient is out of date and the author no longger maintain it on github.Fortunately there have a alternative one named verb which is more powerful and customizable. Verb support url template which makes you change different environment more conveniently.Also verb supports variables and picture query and upload.In org mode start verb just use `C-c C-r` as a previous command,example `C-c C-r C-f` will execute http request with your config,So verb is really fancy right?

usage
Use command to connect redis database.The most convenient thing is you could index your content as iredis have integrated with jq command.

This step can help you compile neo emacs faster,It only takes 3 minutes to install using the release package on my Mac laptop. Otherwise it would take me 15 minutes. The release installation package is a better choice for users with unstable networks and those who need to frequently reinstall neoemacs.
Release package contains the git repository of related dependencies.The compiled directory files are removed and the .git directory is retained,So that you can perform subsequent upgrades.
I will update the Release package once a month, And test them in advance and revise them for compatibility with upstream projects.
For customize farther, there have some documentation you need read.
