raiagent ——[ …it is possibly good ]——

Welcome to raiagent, the third-party Gentoo overlay where Raia and gentlemanly conduct collide.

+ = raiagent


raiagent is installable via the post-modern eselect repository module, superseding the antiquated layman command:

  • Install the eselect repository module (if needed).

      $ emerge --ask app-eselect/eselect-repository
      $ mkdir -p /etc/portage/repos.conf
  • Add and synchronize this overlay.

      $ eselect repository enable raiagent
      $ emerge --sync raiagent
  • Prepare for Gentoo-based winnage.


raiagent publishes well-documented ebuilds unabashedly biased toward technological self-empowerment.1

1. We actually believe most of the specious doggerel tastelessly defibrillating that sentence.


Notable command-line interface (CLI) ebuilds include:


Notable Japanese-centric ebuilds include:

  • mangal, a low-level terminal user interface (TUI) for finding, fetching, and locally reading Japanese manga – complete with Vi[M]-like key bindings. raiagent unofficially hosts mangal ebuilds.


Notable peer-to-peer (P2P) ebuilds include:

  • ZeroNet, a peer-to-peer web hosting network brokered with demonetized BitCoin blockchain semantics distributed over the decentralized BitTorrent protocol complete with optional Tor-based traffic anonymization. Yeah. It's pretty special. raiagent officially hosts ZeroNet ebuilds. Tragically, ZeroNet is no longer actively maintained. Until someone sufficiently young and idealistic creates a well-maintained friendly fork supporting the modern Python ecosystem, we have no choice but to remove all traces of ZeroNet from ::raiagent.


Notable Python ebuilds include:

  • Pure-Python profilers, including:
    • tuna, a newer browser-based UI for visualizing files produced by deterministic Python profilers. Although comparable to SnakeViz, tuna output is more factual than SnakeViz output and thus recommended for modern profiling workflows. raiagent unofficially hosts tuna ebuilds.
  • Pure-Python PEP-compliant build systems, including:
    • Hatch, the increasingly popular project management toolchain recently embraced by the Python Packaging Authority (PyPA). raiagent unofficially hosts Hatch ebuilds.
  • Pure-Python PEP-compliant runtime type checkers, including:
    • beartype, the un:bear:ably fast runtime type checker guaranteeing O(1) time complexity, coauthored by the author of this overlay. Unsurprisingly, raiagent officially hosts beartype ebuilds.
    • pyright, Microsoft's permissively licensed open-source static type checker. Due to its strong performance guarantees, pyright is typically the default static type-checking solution for Python in Interactive Development Environments (IDEs) as diverse as VSCode and Vim. raiagent unofficially hosts pyright ebuilds.
  • Bluetooth Low Energy platform Agnostic Klient (BLEAK), a popular asyncio-based Bluetooth Low Energy (BLE) framework with extensive platform-portable native support for both mobile and non-mobile app stacks. raiagent unofficially hosts BLEAK ebuilds.
  • The full Kivy stack, including:
  • Streamlit, a popular web dashboarding framework oriented towards data science and machine learning. raiagent officially hosts Streamlit ebuilds.


Notable MicroPython and/or CircuitPython ebuilds include:

  • Remote CLI-based controllers, REPLs, and shells – including:
    • mpremote, MicroPython's official first-party remote controller that also transparently supports CircuitPython. raiagent unofficially hosts mpremote ebuilds.
    • rshell, a once-popular MicroPython-specific remote shell largely superseded by mpremote. Nonetheless, raiagent unofficially hosts rshell ebuilds.


Notable "enthusiast" ebuilds include:

  • AntiMicroX, a cross-platform gamepad->{keyboard,mouse} GUI enabling gamepad support in arbitrary games lacking native gamepad support. raiagent unofficially hosts AntiMicroX ebuilds.
  • Munt, a cross-platform software synthesiser emulating pre-GM Roland MIDI devices (e.g., MT-32) commonly supported by MS-DOS-era games. raiagent unofficially hosts Munt ebuilds.
  • VGMPlay, a cross-platform audio player and converter effectively emulating all sequenced video game sound chips and hence supporting all sequenced video game music – ever. As RetroArch is to game emulation, VGMPlay is to game audio emulation. raiagent unofficially hosts VGMPlay ebuilds.


Notable roguelike (i.e., games featuring permanent death as a prominent mechanic) ebuilds include:

Interactive Fiction (IF)

Notable interactive fiction (i.e., parser games featuring text-based control schemes) ebuilds include:


Notable scientifical ebuilds include:

  • BETSE (Bio Electric Tissue Simulation Engine), a cross-platform pure-Python CLI-based finite volume simulator for 2D computational multiphysics problems in the life sciences coauthored by the author of this overlay. Needless to say, raiagent officially hosts BETSE ebuilds.
  • BETSEE (Bio Electric Tissue Simulation Engine Environment), a cross-platform pure-Python PySide2-based Qt 5 GUI for BETSE coauthored by the author of this overlay. Again, raiagent officially hosts BETSEE ebuilds.


raiagent is thanks to the concerted efforts of numerous committers and issue reporters – especially:

  • Nikolai Aleksandrovich Pavlov (ZyX-I), whose gracious contributions to the suite of Powerline ebuilds has been immeasurably invaluable. Thanks, Nikolai. Your Sisyphean efforts will not go unremembered.
