My Emacs Configuration

Environment

Using Windows Terminal + WSL2

Configuration

Windows Terminal

Open Windows Terminal settings, select “Open JSON file”, and add the following color scheme under "schemes":

"schemes":
    [
        {
            "background": "#0D1117",
            "black": "#484F58",
            "blue": "#58A6FF",
            "brightBlack": "#6E7681",
            "brightBlue": "#79C0FF",
            "brightCyan": "#56D4DD",
            "brightGreen": "#56D364",
            "brightPurple": "#D2A8FF",
            "brightRed": "#FFA198",
            "brightWhite": "#FFFFFF",
            "brightYellow": "#E3B341",
            "cursorColor": "#2F81F7",
            "cyan": "#39C5CF",
            "foreground": "#E6EDF3",
            "green": "#3FB950",
            "name": "GitHub-Dark-Default",
            "purple": "#BC8CFF",
            "red": "#FF7B72",
            "selectionBackground": "#E6EDF3",
            "white": "#B1BAC4",
            "yellow": "#D29922"
        }
    ],

- In your Arch Linux profile under Appearance:
  - Set the color scheme to GitHub-Dark-Default
  - Use the FiraCode Nerd Font
  - Set background opacity to 86% and enable Acrylic effect
  - In the Advanced tab:
  - Disable sound notifications, enable window flash and taskbar flash instead

## Arch Linux

Install necessary packages:
```bash
# Install emacs-nox
sudo pacman -Sy emacs-nox

pacman -Sy emacs-nox

pacman -Sy clang clangd clang-format rust-analyzer

# After installing Rust:
rm ~/.cargo/bin/rust-analyzer
ln -s /usr/bin/rust-analyzer ~/.cargo/bin/rust-analyzer

cargo install --git https://github.com/bergercookie/asm-lsp asm-lsp

# Generate asm-lsp config file (optional)
asm-lsp gen-config

Emacs Configuration

Below is my .emacs configuration file. It includes support for:

• C/C++, Rust, and Assembly (asm-lsp) LSP integration
• Tree-sitter highlighting
• Common development plugins (magit, projectile, goto-line-preview, neotree, etc.)
• Clipboard sharing between WSL and Windows
