## Requirements
- Linux (reads `/proc`)
- CMake ≥ 3.20
- GCC 13+ or Clang 16+ (C++23)
- Git
Dependencies ([FTXUI](https://github.com/ArthurSonzogni/FTXUI), [{fmt}](https://github.com/fmtlib/fmt)) are fetched automatically.
## Build
```bash
git clone https://github.com/yourname/htop_killer
cd htop_killer
./build.sh run
```
Other targets:
```bash
./build.sh release # build only
./build.sh debug # with ASan + UBSan
./build.sh install # to /usr/local/bin
./build.sh clean
./build.sh lint # clang-tidy
```
Manual:
```bash
cmake -S . -B build -DCMAKE_BUILD_TYPE=Release -G Ninja
cmake --build build -j$(nproc)
./build/htop_killer
```
Docker:
```bash
docker build -t htop_killer .
docker run -it --pid=host --privileged htop_killer
```
## Keys
| Key | Action |
|-----|--------|
| `Tab` | next tab |
| `1` `2` `3` `4` | CPU / MEM / NET / DISK |
| `p` | process table |
| `c` | per-core CPU bars |
| `f` | cycle sort (CPU → MEM → PID → Name) |
| `j` `k` / `↓` `↑` | scroll processes |
| `?` | help overlay |
| `q` `Esc` | quit |
## Structure
```
include/
core/ types, ring_buffer, history, data_store
collectors/ interfaces + Linux implementations
ui/ widgets, theme, app loop
src/
collectors/ .cpp implementations
main.cpp
```
Data flows one way: collectors write to `DataStore`, UI reads from it. The shared state is guarded by `std::shared_mutex`. History is stored in fixed-size ring buffers (120 samples ≈ 2 min at 1 Hz).
