ClearFX
because a blank screen is boring as fuck
Install · Usage · Animations · Create · Config
ngl i got so sick of watching my terminal just instantly vanish every time i ran clear, so i made this. ClearFX literally hijacks ur standard clear command (or ls, or whatever u want) and drops a crazy terminal animation before wiping the screen. u could be looking at some messy ass logs and one second later ur watching a tiny city shut off its lights or some ascii matrix rain.
it runs completely offline, uses a super safe sandboxed .clearfx package format so nobody can run malicious code on ur machine, and has a whole marketplace u can browse straight from the terminal.
Installation
pip install clearfx
(if u already have it, just do pip install -U clearfx to update)
Shell Integration
to actually make your clear command use this, u gotta set up the shell hooks:
clearfx setup-shell
it auto-detects what ur using (bash, zsh, fish, or powershell) and injects the hook. don't worry, it makes a backup of your config first just in case.
after that, just restart your shell or resource it:
source ~/.bashrc
and if u ever wanna wipe it completely from your machine:
clearfx reset
Usage
play a random animation
clearfx play
wrap any command
want an animation to play every time you run ls or git?
clearfx wrap ls --anim aurora-fold
list what we got
clearfx list
clearfx list --community
tweak the playback
clearfx play --duration 700 # speed it up (ms)
clearfx play --fps 60 # buttery smooth
clearfx play --seed 42 # exact same output every time
clearfx play --ascii # force ascii mode
clearfx play --monochrome # no colors
clearfx play --reduced-motion # accessibility mode (less crazy)
emergency kill switch
if something breaks or u just want it off right now:
export CLEARFX_DISABLE=1

Configuration
all ur settings live in your platform's standard config directory (like ~/.config/clearfx/config.toml on linux).
clearfx config # check current settings
clearfx config set duration_ms 900 # change something rq
example config:
enabled = true
duration_ms = 1100
fps = 30
reduced_motion = false
ascii_only = false
attribution_position = "auto"
Accessibility
if ur terminal doesn't support crazy unicode or colors, u can force it:
clearfx config set ascii_only true
clearfx config set monochrome true
if u want simpler, gentler animations with fewer flashing lights:
clearfx config set reduced_motion true
Marketplace
u can grab designs other people have made from the community catalog:
clearfx search "space"
clearfx install aurora-fold
clearfx update
Creating Designs
i wanted to make it insanely easy to build ur own animations using python.
clearfx create my-animation
cd my-animation
# Edit src/design.py
clearfx preview .
clearfx validate .
clearfx pack .
(check out docs/CREATOR_SDK.md for the full sdk tutorial on how to write these)
Security Model
running random python code every time u clear ur screen is a terrible fucking idea.
so, community packages use a .clearfx file format. it's just a zip archive with a declarative JSON scene definition. there are ZERO .py files, ZERO arbitrary code execution, and ZERO network access when playing. it's completely sandboxed so u can install shit without worrying.
Development Setup
wanna mess with the code?
git clone https://github.com/random-unknown-username/clearfx.git
cd clearfx
python -m venv .venv
source .venv/bin/activate
pip install -e ".[dev,client,recording]"
to run the web marketplace locally for testing, the frontend code is included in the repo. just start it up!
Troubleshooting
if things go weird:
- run
clearfx doctorto see wtf is wrong - if your terminal gets messed up (it shouldn't, but just in case), type
resetand hit enter.
