My personal Emacs configuration

(Note): This configuration hasn’t been updated for a while since I start to use doom emacs rather spacemacs.

Installation

Step1: Install Emacs

Install Emacs-mac on Mac

• Method 1: Use brew cask(Recommended)

  brew tap railwaycat/emacsmacport
  brew cask install emacs-mac-spacemacs-icon
      

• Method 2: Just brew, need compiling. (more customization)

  brew tap railwaycat/emacsmacport
  rm -r /Applications/Emacs.app
  brew install emacs-mac --with-spacemacs-icon --with-gnutls --with-natural-title-bar
  # create alias in /Applications
  ln -Fs `sudo find /usr/local -name "Emacs.app"` /Applications/Emacs.app
      

  Notes: (just for method 2)

  1. natural-title-bar usage here.
  2. Solution to incoming network connection: Codesign your Emacs.app. Instructions over here. codesign --deep --force --verbose --sign ztlevi /usr/local/opt/emacs-mac/Emacs.app

Install Emacs on Linux

# Ubuntu
sudo apt-get insatll emacs
# Arch
sudo pacman -S emacs

Step2: Install Spacemacs

rm -r ~/.emacs.d
git clone https://github.com/syl20bnr/spacemacs -b develop ~/.emacs.d

Step3: Configuration and Dependencies

This Emacs configuration is written for Emacs 25.1+ on Mac OS X 10.11+ and Linux Arch. Windows users may need to tweak the config for themselves.

1. Clone my configuration:

   git clone --recurse-submodules -j8 https://github.com/ztlevi/spacemacs-config.git ~/.spacemacs.d
       

2. Install all-the-icons fonts by M-x all-the-icons-install-fonts. I’m using Operator Mono Lig font(supports ligatures), you could change it under dotspacemacs-default-font.
3. Dependencies needed
   • Install dependencies including search tools, utils, and linters.

     # search tool
     brew install ripgrep grep
     # utils
     brew install hub watchman gpg2 coreutils ctags gnu-tar
     # linter
     brew install shellcheck aspell hadolint
             

     Note: for windows users, aspell is used instead. ripgrep can be installed via choco

   • npm

     npm install -g prettier js-beautify live-server import-js
             

   • pip: autopep8, importmagic, ipython

     pip3 install ipython pylint autopep8 importmagic epc
             

   • go: go-langserver, gocode, gogetdoc, godef, godoctor

     brew install go
     
     # lsp
     go get -u github.com/sourcegraph/go-langserver
     
     go get -u -v github.com/nsf/gocode
     go get -u -v github.com/rogpeppe/godef
     go get -u -v golang.org/x/tools/cmd/guru
     go get -u -v golang.org/x/tools/cmd/gorename
     go get -u -v golang.org/x/tools/cmd/goimports
     go get -u -v github.com/zmb3/gogetdoc
     go get -u -v github.com/cweill/gotests/...
     go get -u github.com/haya14busa/gopkgs/cmd/gopkgs
     go get -u -v github.com/davidrjenni/reftools/cmd/fillstruct
     go get -u github.com/josharian/impl
     
     go get -u -v github.com/alecthomas/gometalinter
     gometalinter --install --update
     
     go get -u github.com/golangci/golangci-lint/cmd/golangci-lint
             

4. Language Server Protocol: Install the lsp for your languages. A few examples are listed below.

   # Javascript
   npm i -g typescript
   
   # Vue
   npm install vue-language-server -g
   
   # python
   # pyls-mypy is a type integration for Python
   pip3 install 'python-language-server[all]' pyls-isort
   
   # cquery for c++
   brew tap twlz0ne/homebrew-cquery
   brew install cquery
       

5. According to the discussion [h[https://emacs-china.org/t/topic/6453/6][here]], the following codes will speed up Emacs GUI startup time.

   defaults write org.gnu.Emacs Emacs.ToolBar -string no
   defaults write org.gnu.Emacs Emacs.ScrollBar -string no
   defaults write org.gnu.Emacs Emacs.MenuBar -string no
       

Usage

1. If you want to map jk as evil escape key, add the following line in customize.el -> custom-set-variables and delete evil-escape package in init.el -> dotspacemacs-excluded-packages.

   '(evil-escape-delay 0.2)
   '(evil-escape-key-sequence "jk")
       

2. SPC f g (rgrep) can help to search and apply the file masks (*.py).
3. Git-Link: You can use the universal argument SPC u with M-x spacemacs/git-link (SPC g l l) to select a remote repository. Local settings are managed via the repository’s git configuration. They can be set via: git config --local --add git-link.remote upstream Local settings have precedence over global settings. git-link.remote: Name of the remote to link to. git-link.branch: Name of the remote branch to link to.
4. Cquery Project setup compile_commands.json (Best). Remember to copy/symlink it to the project root.
5. Use counsel-etags-find-tag-at-point (g F) to choose the etags directory and find candidates.
6. Atomic Chrome is very useful to edit the textarea in Chrome. You will need to install the Chrome extension here.
7. Prodigy is great to define your own services and fire up the service easily. Custom setting is under function ztlevi-misc/post-init-prodigy

   Note: If you are on a Mac, disable nap mode for Emacs, otherwise requests will be very slow when Emacs enters nap mode:

   defaults write org.gnu.Emacs NSAppSleepDisabled -bool YES
       

8. To change the home page banner, configure the setting in ~dotspacemacs-startup-banner ‘”~/.spacemacs.d/icons/banner.png”~.
9. Encrypt org entries by using C-c C-c to set secret tag for the entry. Save the file and input the passcode. Then the entry will be encrypted. Decrypt the entry by using org-decrypt-entry.

What’s the highlight of this configuration

1. It’s a highly customize optimized Spacemacs configuration, it’s relied on the develop branch of the officially Spacemacs.
2. I prefer to the Ivy completion interface, so I removed many helm related packages but keep the helm-ag package. The counsel-ag counterpart is not powerful as helm-ag.
3. I also removed some packages I don’t have any chance to use. The complete lists are in the exclude section of the init.el file.
4. I also exclude the Spaceline package, cause it’s easy to frozen the Emacs with this package enabled. So I create my own mode line configuration based Spaceline.
5. The Swiper package sometimes frozen the Emacs UI only when you split the window. You could use `pkill -SIGUSR2 -i emacs` command line to rescue.
