# AGENTS.md - Arch Linux Configuration Repository
# AGENTS.md Arch Linux 声明式配置仓库
## Project Overview
## 概要
This is a declarative Arch Linux configuration repository managed by `decman` (Declarative package & configuration manager for Arch Linux). The project uses a Python source file to declare packages, system files, and dotfiles.
使用 [decman](https://github.com/kiviktnm/decman) 声明式管理 Arch Linux 系统配置。Python 源文件声明包、系统文件、dotfiles 和 systemd 服务。
**Primary Tool**: `decman` - Declarative package & configuration manager for Arch Linux
**Target Environment**: Arch Linux (primarily WSL, but supports bare metal)
**Language**: Shell scripts (Bash), Python configuration (source.py)
- **运行环境**Arch Linux(主要面向 WSL,兼容裸机)
- **语言**Python(配置)、Bash(引导脚本)
- **包管理器**uv(开发依赖)、pacman/yay(系统包)

## Build/Test/Sync Commands
### Primary Commands
## 命令
```bash
# Apply configuration (install/update packages, sync files)
# 应用配置(安装/更新包、同步文件、启用服务)
sudo decman
# First-time run (specify source file)
sudo decman --source ~/.config/arch-config/source.py
# 首次运行(需指定 source 路径)
sudo decman --source ~/.config/archlinux-config/source.py
# Skip specific plugins
# 跳过特定插件
sudo decman --skip aur
sudo decman --skip flatpak
sudo decman --skip systemd
# Only apply file operations
# 仅同步文件
sudo decman --no-hooks --only files
# Debug mode
# 调试模式
sudo decman --debug
```
### Installation Commands
### 验证
```bash
# WSL first-time setup (as root)
curl -fsSL https://git.furtherverse.com/imbytecat/archlinux-config/raw/branch/main/scripts/wsl-init.sh | bash -s -- <username>
# Python 语法检查(所有 .py 文件)
python -c "import py_compile; py_compile.compile('source.py', doraise=True)"
python -c "import py_compile; py_compile.compile('docker_module.py', doraise=True)"
python -c "import py_compile; py_compile.compile('locale_module.py', doraise=True)"
# Install decman and apply config (as regular user)
curl -fsSL https://git.furtherverse.com/imbytecat/archlinux-config/raw/branch/main/scripts/install.sh | bash
```
### Testing Scripts
```bash
# Test shell scripts for syntax errors
# Shell 语法检查
bash -n scripts/install.sh
bash -n scripts/wsl-init.sh
# Run shellcheck if available
shellcheck scripts/*.sh
# Validate Python syntax
python -c "import py_compile; py_compile.compile('source.py', doraise=True)"
# 同步开发依赖
uv sync
```
## Code Style Guidelines
## decman 执行顺序
### Shell Scripts
声明顺序必须匹配执行顺序,从上到下阅读即从上到下执行:
**Shebang & Options**:
- Always use `#!/bin/bash` (not `#!/bin/sh`)
- Start with `set -euo pipefail` for safety
**Error Handling**:
- Check command success with `if ! command; then`
- Validate user input before proceeding
- Provide clear error messages in Chinese (matching project language)
- Exit with non-zero status on errors
**Variables**:
- Use `UPPERCASE` for constants and environment variables
- Use `lowercase` for local variables
- Always quote variables: `"$VAR"` not `$VAR`
**Conditionals**:
- Prefer `[[ ]]` over `[ ]` for tests
- Use `&> /dev/null` for suppressing output
- Check command existence: `if command -v cmd &> /dev/null; then`
**User Feedback**:
- Use `echo "==> Action..."` for major steps
- Use Chinese for user-facing messages
- Show clear success indicators: `✓`
**Example Pattern**:
```bash
#!/bin/bash
set -euo pipefail
USERNAME="${1:-}"
if [ -z "$USERNAME" ]; then
echo "用法: script.sh <参数>"
exit 1
fi
echo "==> 执行操作..."
if ! some_command; then
echo "错误:操作失败"
exit 1
fi
echo "✓ 完成!"
```
files → pacman → aur → systemd
```
### Python Configuration (source.py)
`source.py` 中的声明分区按此排列:系统文件 → 用户配置 → modules → pacman 包 → AUR 包。
**Structure**:
- Use section dividers (`# ── Section ──`) to separate logical groups
- Group packages by purpose (基础工具, 开发工具, Zsh)
- Keep packages in sets (`|=` syntax)
- Use `os.environ.get("SUDO_USER")` for dynamic username
## 代码风格
**Example Pattern**:
### Pythonsource.py 及模块)
**source.py 结构**
-`# ── Section ──` 分隔逻辑分区
- 包集合用 `|=` 语法,元素按字母排序
- `SUDO_USER` 必须存在,不设 fallback——没有则抛 `SourceError`
- 文件默认权限 `0o644`,仅需特殊权限时显式指定(如 sudoers `0o440`
**模块模式**(适用于需要 hook 或跨步骤声明的场景):
```python
import os
import decman
from decman import File
from decman import Module
from decman.plugins.pacman import packages
from decman.plugins.systemd import units
USERNAME = os.environ.get("SUDO_USER", "imbytecat")
HOME = f"/home/{USERNAME}"
class DockerModule(Module):
def __init__(self):
super().__init__("docker")
decman.pacman.packages |= {"git", "neovim", "zsh"}
decman.aur.packages |= {"decman", "bun"}
@packages
def packages(self) -> set[str]:
return {"docker", "docker-compose"}
decman.files["/etc/pacman.d/mirrorlist"] = File(
source_file="./system/etc/pacman.d/mirrorlist",
)
decman.files[f"{HOME}/.zshrc"] = File(
source_file="./home/.zshrc",
owner=USERNAME,
)
@units
def units(self) -> set[str]:
return {"docker.service"}
```
### Git Workflow
**何时用模块 vs 直接声明**
- 需要 `on_change` hook(如 `locale-gen`)→ Module
- 需要绑定 packages + systemd units → Module`@packages` + `@units` 装饰器)
- 纯静态文件、无副作用 → 直接在 `source.py``File()`
**Commit Messages**:
- Follow commitlint conventional commits format
- Use Chinese for commit messages (matching project language)
- Format: `<type>(<scope>): <subject>`
- Types: `feat`, `fix`, `docs`, `style`, `refactor`, `test`, `chore`
- Examples:
- `feat(source): 添加开发工具包`
- `fix(scripts): 更新安装脚本`
- `docs: 更新 README 说明`
- `chore(files): 更新镜像源列表`
### Shell 脚本
**Branching**:
- Main branch: `main`
- Work directly on main for personal config repos
- Shebang`#!/bin/bash`
- 安全选项:`set -euo pipefail`
- 变量引用:始终加双引号 `"$VAR"`
- 条件测试:优先 `[[ ]]`
- 命令检测:`if command -v cmd &> /dev/null; then`
- 用户消息:中文,用 `echo "==> 动作..."` 标记主要步骤,`✓` 表示完成
- 错误消息:`echo "错误:描述"` + `exit 1`
## Important Notes for Agents
### Git
1. **decman is the source of truth**: Don't manually install packages. Add them to `source.py` and run `sudo decman`.
- 提交消息:中文,conventional commits 格式
- 格式:`<type>(<scope>): <中文描述>`
- 类型:`feat` / `fix` / `docs` / `refactor` / `chore`
- 示例:`feat(docker): 添加 Docker 支持并重排声明顺序`
- 分支:直接在 `main` 上工作
2. **Pacman vs AUR**: Packages must be correctly categorized into `decman.pacman.packages` (official repos) and `decman.aur.packages` (AUR).
## Agent 须知
3. **System files**: Files in `system/` are copied (not symlinked) to system locations by decman. Use `File(source_file=..., permissions=...)` with correct permissions.
1. **decman 是唯一真相**:不要手动装包,加到 `source.py` 或模块里,跑 `sudo decman`
4. **User config**: Files in `home/` are copied to user home by decman. Use `File(source_file=..., owner=USERNAME)`.
2. **Pacman vs AUR**:用 `pacman -Ss` 确认包在官方仓库还是 AUR,分别加到 `decman.pacman.packages``decman.aur.packages`
5. **No dry-run**: decman does not have a `--dry-run` option. Review changes in `source.py` before running `sudo decman`.
3. **系统文件**:源文件放 `system/`,目录结构对应目标路径(`system/etc/foo.conf``/etc/foo.conf`)。decman 复制(非 symlink)到目标位置。
6. **Runs as root**: `sudo decman` executes `source.py` as root. `SUDO_USER` contains the original username.
4. **用户配置**:源文件放 `home/`,必须指定 `owner=USERNAME`
7. **Language**: User-facing messages and documentation are in Chinese. Keep this consistent.
5. **Runs as root**`sudo decman` 以 root 执行 `source.py``SUDO_USER` 是调用 sudo 的原始用户名,不要 fallback。
8. **Safety first**: Scripts use `set -euo pipefail` and validate inputs.
6. **开发环境**`pyproject.toml` + `uv sync` 管理开发依赖(decman、decman-pacman、decman-systemd),仅用于 IDE 类型检查,不影响运行时。
9. **Idempotency**: Scripts should be safe to run multiple times.
7. **幂等性**:所有脚本和配置必须可安全重复执行。
10. **Bootstrap flow**: `scripts/install.sh` handles one-time setup (yay, decman, locale-gen, chsh). After that, `sudo decman` handles ongoing management.
8. **语言**:用户消息、文档、提交消息使用中文。
## Common Tasks
## 常见任务
**Add a new package**:
- Determine if it's pacman or AUR
- Add to the appropriate set in `source.py`
- Run `sudo decman`
**添加包**:确认 pacman/AUR → 加到 `source.py` 对应集合 → `sudo decman`
**Add a new system file**:
- Place the file in `system/` matching target path structure (e.g., `system/etc/foo.conf``/etc/foo.conf`)
- Add `decman.files["/etc/foo.conf"] = File(source_file="./system/etc/foo.conf")` to `source.py`
- Run `sudo decman`
**添加系统文件**:放 `system/` → 在 `source.py``File(source_file=...)``sudo decman`
**Add a new dotfile**:
- Place the file in `home/`
- Add `decman.files[f"{HOME}/.config/foo"] = File(source_file="./home/foo", owner=USERNAME)` to `source.py`
- Run `sudo decman`
**添加 dotfile**:放 `home/` → 在 `source.py``File(source_file=..., owner=USERNAME)``sudo decman`
**Update an existing configuration file**:
- Edit the source file in `system/` or `home/`
- Run `sudo decman`
**添加需要 systemd 服务的软件**:创建 Module 文件,用 `@packages` + `@units` 装饰器 → 在 `source.py` 注册 → `sudo decman`
**添加开发依赖(decman 插件)**:加到 `pyproject.toml``[dependency-groups] dev``[tool.uv.sources]``uv sync`
