"Not a dashboard. An instrument panel."

Pulse is a terminal system monitor for people who want high-density telemetry with a bit of style. Built on Textual and psutil.

✨ Features

• Live telemetry for CPU, memory, disk I/O, storage, network, and processes.
• Transcendence mode — press X on any focused panel for a full-screen, interactive view.
• Process and container control — terminate, renice, and manage Docker containers. Every destructive action confirms first and names its exact target.
• Six themes — Nord, Dracula, Monokai, Dark, Solarized, Gruvbox. Your choice is remembered.
• Configurable refresh rate, from 0.1s for micro-stutter hunting to 60s for a background glance.

How metrics are collected

On Linux, Pulse reads /proc directly and computes its own CPU and per-process deltas. On Windows it uses GlobalMemoryStatusEx for memory and psutil elsewhere; on macOS and other platforms it uses psutil throughout. psutil is a dependency on every platform.

🚀 Installation

pip install pulse-monitor

Then launch from anywhere:

pulse

Docker container monitoring is optional, because access to the Docker socket is root-equivalent on the host:

pip install "pulse-monitor[docker]"

Process and container actions

Pulse will not act on processes where a mistake takes down your session: itself, its parent shell, PID 1 or the session leader on POSIX, and the reserved Windows system PIDs. It never escalates privileges on its own — if a kill is denied, it says so and offers a force kill as a separate, explicit choice.

⚙️ Configuration

Config lives at %APPDATA%\pulse\config.toml on Windows, $XDG_CONFIG_HOME/pulse/config.toml (usually ~/.config/pulse/) elsewhere.

[ui]
theme = "nord"        # nord | dracula | monokai | textual-dark | solarized-dark | gruvbox

[core]
refresh_rate = 1.0    # seconds, clamped to 0.1 - 60.0

Unknown or out-of-range values fall back to the defaults rather than breaking startup.

🛠️ Development

git clone https://github.com/Fatin-Ishraq/Pulse.git
cd Pulse
python -m venv .venv && source .venv/bin/activate   # Windows: .venv\Scripts\activate
pip install -e ".[test]"
pytest

Run it from the source tree with pulse or python -m pulse.

🚀 Release Process

Publishing to PyPI uses GitHub Actions with Trusted Publishing — no API tokens in secrets.

1. Bump __version__ in src/pulse/__init__.py (the package version is read from there).
2. Update CHANGELOG.md.
3. Confirm CI is green on main — the Linux job is the one that matters.
4. Tag and push:

   git tag v0.5.0
   git push origin v0.5.0
   

The tag must match the version in __init__.py. PyPI will not accept a version number twice, so a mismatched tag burns that version permanently.
