Genact - 🌀 A nonsense activity generator

Overview

genact - a nonsense activity generator

CI DockerHub Crates.io license Stars Downloads

Pretend to be busy or waiting for your computer when you should actually be doing real work! Impress people with your insane multitasking skills. Just open a few instances of genact and watch the show. genact has multiple scenes that pretend to be doing something exciting or useful when in reality nothing is happening at all.

Installation

Packaging status

You don't have to install anything! For your convenience, prebuilt binaries for Linux, OSX and Windows are provided here that should run without any dependencies. Additionally, there is a web version at https://svenstaro.github.io/genact/

It's compatible with FreeBSD, Linux, macOS, Windows 10 (it needs a recent Windows 10 to get ANSI support) and most modern web browsers that support WebAssembly.

On FreeBSD: You don't have to do anything special here. Just run

pkg install genact
genact

On Linux: Download genact-linux from the releases page and run

chmod +x genact-linux
./genact-linux

On macOS: Download genact-osx from the releases page and run

chmod +x genact-osx
./genact-osx

A homebrew package is also available. To install it this way, run

brew install genact

On macOS, you can also install via MacPorts:

sudo port install genact

On Windows: Download genact-win.exe from the releases page and double click it.

With Cargo: If you have a somewhat recent version of Rust and Cargo installed, you can run

cargo install genact
genact

Running

To see a list of all available options, you can run

./genact -h

or

cargo run -- -h

or (on Docker)

docker run -it --rm svenstaro/genact -h

Usage

genact 0.11.0

A nonsense activity generator

USAGE:
    genact [FLAGS] [OPTIONS]

FLAGS:
    -h, --help            Prints help information
    -l, --list-modules    List available modules
    -V, --version         Prints version information

OPTIONS:
        --exit-after-modules <exit-after-modules>    Exit after running this many modules
        --exit-after-time <exit-after-time>          Exit after running for this long (format example: 2h10min)
    -m, --modules <modules>...
            Run only these modules [possible values: botnet, bootlog, kernel_compile,
            memdump, cargo, cc, composer, docker_build, cryptomining,
            download, mkinitcpio, weblog, docker_image_rm, simcity]
    -s, --speed-factor <speed-factor>                Global speed factor [default: 1]

Web usage

In the web version, you can run specific modules by providing them as ?module parameters like this: https://svenstaro.github.io/genact?module=cc&module=memdump

You can also provide a ?speed-factor like this: https://svenstaro.github.io/genact?speed-factor=5

Building

You should have a recent version of rust and cargo installed.

Then, just clone it like usual and cargo run to get output:

git clone https://github.com/svenstaro/genact.git
cd genact
cargo run --release

Releasing

This is mostly a note for me on how to release this thing:

  • Make sure CHANGELOG.md is up to date.
  • cargo release --dry-run
  • cargo release
  • Releases will automatically be deployed by Github Actions.
  • Docker images will automatically be built by Docker Hub.
  • Update Arch package.
Comments
  • New Module: docker_build

    New Module: docker_build

    This is currently WIP.

    Managed to get everything working so far, the last thing missing is to properly print instructions. Pulling instructions from a list like all other data wouldn't be the problem, but I would also like to print generic output for instructions that run and are not cached.

    Example:

    RUN ls -la
    

    should output something like

    total 208
    drwxr-xr-x  21 kg  staff    672 Dec 12 09:36 .
    drwxr-xr-x@  9 kg  staff    288 Dec  5 00:17 ..
    -rw-r--r--   1 kg  staff    219 May 21  2019 .editorconfig
    drwxr-xr-x  15 kg  staff    480 Dec 12 11:01 .git
    -rw-r--r--   1 kg  staff     28 Jun  1  2018 .gitignore
    -rw-r--r--   1 kg  staff   2812 May 21  2019 .travis.yml
    

    but I'm not sure how to implement this. Any ideas?

    Also, hope the current code is not that horrifying. 😬

  • First try on an implementation for a Docker Genact plugin

    First try on an implementation for a Docker Genact plugin

    I just tried to implement a Docker plugin based on #64. It basically works but I couldn't make the SHA256 generation work as there are type conflicts.

    The following error is thrown in src/docker.rs:22:

    return sha256.result();
               ^^^^^^^^^^^^^^^ expected struct `std::string::String`, found struct `generic_array::GenericArray`
    

    Corresponding code:

    fn gen_hash() -> String {
        let mut rng = rand::thread_rng();
        let mut sha256 = Sha256::new();
        sha256.input(
            rng.sample_iter(&Alphanumeric)
            .take(30)
            .collect::<String>()
        );
        return sha256.result();
    }
    

    I tried several things and searched for ways to convert from one type to a string but I had no luck. I also found no information about returning the hash result as a string directly. Perhaps this is an easy fix but I am not familiar with Rust so I am stuck at the moment.

    Docker support

    Could you create a docker image and push to docker hub for running it without downloading any additional files? This seems to be quick option to get new users as they only have to run single command instead of trying to download correct binaries and then figure out how to launch them.

    This modules combines the spinner from FGRibreau/spinners with these phrases.

  • Add initial implementation of `julia` module

    Add initial implementation of `julia` module

    This is an initial implementation of the module julia. It simulates the process of updating all the packages in a project.

    There are still some features missing:

    • [x] ~downloading artifacts~
    • [x] ~building artifacts~
    • [x] ~possible old manifest format~
    • [x] ~garbage collection~
    • [ ] dynamic package precompilation

    If there is some interest, I can work on adding them.

    Here is a preview of what it looks like (this is an old version without artifacts and precompilation progress bar):

  • Heads-up: FreeBSD port is on its way

    Heads-up: FreeBSD port is on its way

    FYI, genact is going to be included in the FreeBSD ports collection soon.

    The PR is available here: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=228306

    When it's pulled it will be able to install a prebuilt genact package with:

    pkg install genact
    

    Nice and easy. You can start generating nonsense in no time.

    Cheers! 😄

  • Add burst mode to bootlog module

    Add burst mode to bootlog module

    What does this PR do?

    It adds burst mode to the bootlog module

    Description of Task to be completed?

    • The bootlog module should behave a bit more realistically in that it should sometimes burst a bunch of lines really quickly

    How should this be manually tested?

    • Run cargo run -- -m bootlog in the project
    • The output should be printed in quick succession from time to time.

    Maybe I can cut the size down by compressing stuff in data/ during build time (with build.rs) and then decompressing it during runtime. Gotta investigate.

    I added some lines to the Dockerfile to utilize multi-stage builds. This reduces the image size to around ~60MB by only adding the final genact binary to the image.

    Add an on-screen percentage based on the -exitafter time given

    Thanks for creating such a handy little tool. It would be great if a percentage could be shown on the screen that correlated with the time given in the -e or -exitafter switches, so that the percentage complete was calculated based on the remaining time until the process will stop.

    Maybe it can use a fixed row at the bottom of the terminal, with the output continuing above it?
