# hdmistat Design Document
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
hdmistat is a golang daemon that displays system statistics on Linux framebuffers using beautiful bitmap graphics rendered with the IBM Plex Mono font in ultralight weight. It's designed for resource-constrained systems like Raspberry Pis that don't run X11 or Wayland.
|
||||||
|
|
||||||
|
## Architecture
|
||||||
|
|
||||||
|
### Core Components
|
||||||
|
|
||||||
|
1. **Display Package** (`internal/display`)
|
||||||
|
- Interfaces with Linux framebuffer devices
|
||||||
|
- Handles raw image display
|
||||||
|
- Manages framebuffer memory mapping
|
||||||
|
|
||||||
|
2. **Layout Package** (`internal/layout`)
|
||||||
|
- Provides simple text rendering API
|
||||||
|
- Handles font rendering with IBM Plex Mono ultralight
|
||||||
|
- Offers drawing primitives for creating clean layouts
|
||||||
|
- Abstracts away complex image manipulation
|
||||||
|
|
||||||
|
3. **Stat Collector Package** (`internal/statcollector`)
|
||||||
|
- Collects system information (CPU, memory, disk, network, processes)
|
||||||
|
- Returns structured data for rendering
|
||||||
|
- Uses gopsutil for cross-platform system stats
|
||||||
|
|
||||||
|
4. **Renderer Package** (`internal/renderer`)
|
||||||
|
- Converts system stats to images using the layout API
|
||||||
|
- Manages different screen types
|
||||||
|
- Handles screen-specific rendering logic
|
||||||
|
|
||||||
|
5. **Carousel System** (`internal/app`)
|
||||||
|
- Manages multiple screens
|
||||||
|
- Handles automatic screen rotation
|
||||||
|
- Coordinates between collectors, renderers, and display
|
||||||
|
|
||||||
|
### Dependency Injection
|
||||||
|
|
||||||
|
Uses uber/fx for dependency injection to:
|
||||||
|
- Wire together components automatically
|
||||||
|
- Manage component lifecycle
|
||||||
|
- Enable clean separation of concerns
|
||||||
|
- Facilitate testing and modularity
|
||||||
|
|
||||||
|
### CLI Structure
|
||||||
|
|
||||||
|
Uses cobra for command handling:
|
||||||
|
|
||||||
|
- `hdmistat daemon` - Main daemon that takes over framebuffer
|
||||||
|
- `hdmistat install` - Installs systemd unit files and enables the service
|
||||||
|
- `hdmistat status` - Shows current daemon status
|
||||||
|
- `hdmistat info` - Displays system information in terminal
|
||||||
|
|
||||||
|
### Screen Types
|
||||||
|
|
||||||
|
1. **Overview Screen** - Shows:
|
||||||
|
- Hostname
|
||||||
|
- Memory usage
|
||||||
|
- CPU usage
|
||||||
|
- Temperatures
|
||||||
|
- Disk usage
|
||||||
|
- Network interface status (link speeds, IPs, current speeds)
|
||||||
|
|
||||||
|
2. **Configurable Detail Screens**:
|
||||||
|
- Top processes by memory
|
||||||
|
- Top processes by CPU
|
||||||
|
- Largest files
|
||||||
|
- Network traffic details
|
||||||
|
- Custom user-defined screens
|
||||||
|
|
||||||
|
### Configuration
|
||||||
|
|
||||||
|
- YAML-based configuration file
|
||||||
|
- Specifies which screens to show
|
||||||
|
- Screen rotation timing
|
||||||
|
- Custom screen definitions
|
||||||
|
- Font size and layout preferences
|
||||||
|
|
||||||
|
### Logging
|
||||||
|
|
||||||
|
- Uses log/slog for structured logging
|
||||||
|
- Different log levels for debugging
|
||||||
|
- Logs to systemd journal when running as service
|
||||||
|
|
||||||
|
### Font Rendering
|
||||||
|
|
||||||
|
- IBM Plex Mono font in ultralight weight
|
||||||
|
- Embedded in binary for zero dependencies
|
||||||
|
- Anti-aliased rendering for crisp text
|
||||||
|
- Configurable sizes
|
||||||
|
|
||||||
|
### Communication
|
||||||
|
|
||||||
|
Components communicate via interfaces:
|
||||||
|
- `Display` - Show images on framebuffer
|
||||||
|
- `Collector` - Gather system information
|
||||||
|
- `Renderer` - Convert data to images
|
||||||
|
- `Screen` - Define what to display
|
||||||
|
- `Layout` - Text and graphics rendering
|
||||||
|
|
||||||
|
## Implementation Notes
|
||||||
|
|
||||||
|
- All types defined in their respective packages (no separate types package)
|
||||||
|
- Graceful shutdown handling
|
||||||
|
- Error recovery to prevent framebuffer corruption
|
||||||
|
- Efficient memory usage for resource-constrained systems
|
||||||
|
- No external font dependencies (embedded assets)

PREAMBLE
|
||||||
|
The goals of the Open Font License (OFL) are to stimulate worldwide
|
||||||
|
development of collaborative font projects, to support the font creation
|
||||||
|
efforts of academic and linguistic communities, and to provide a free and
|
||||||
|
open framework in which fonts may be shared and improved in partnership
|
||||||
|
with others.
|
||||||
|
|
||||||
|
The OFL allows the licensed fonts to be used, studied, modified and
|
||||||
|
redistributed freely as long as they are not sold by themselves. The
|
||||||
|
fonts, including any derivative works, can be bundled, embedded,
|
||||||
|
redistributed and/or sold with any software provided that any reserved
|
||||||
|
names are not used by derivative works. The fonts and derivatives,
|
||||||
|
however, cannot be released under any other type of license. The
|
||||||
|
requirement for fonts to remain under this license does not apply
|
||||||
|
to any document created using the fonts or their derivatives.
|
||||||
|
|
||||||
|
