McFly

brew install mcfly

cargo install mcfly

# For Bash, add to ~/.bashrc:
eval "$(mcfly init bash)"

# For Zsh, add to ~/.zshrc:
eval "$(mcfly init zsh)"

# For Fish, add to ~/.config/fish/config.fish:
mcfly init fish | source

# Then restart your shell or source your config
source ~/.bashrc  # or ~/.zshrc

mcfly --version

# Check if integrated with your shell
echo $MCFLY_HOME  # Should show McFly's data directory

# Open McFly search interface (replaces Ctrl+R)
Ctrl+R

# Or explicitly search for commands
mcfly search "git commit"

# Search with fuzzy matching
Ctrl+R
# Type partial command: gst
# McFly shows: git status, git stash, etc.

# In McFly search interface:
Ctrl+R              # Open search
Type: command       # Fuzzy search
↑/↓                # Navigate results
Enter               # Execute selected command
Esc                 # Cancel search

# Preview commands
Ctrl+O              # Show more details about highlighted command
Tab                 # Select/deselect commands (multi-select)

# McFly learns as you use it:
# 1. Every command execution is recorded
# 2. Usage patterns are analyzed
# 3. Suggestions are ranked based on:
#    - Directory context
#    - Recent usage frequency
#    - Time patterns
#    - Command success/failure

# The more you use it, the better suggestions become
# After a few weeks of normal usage, suggestions will be highly personalized

# After using these commands several times:
git add .
git commit -m "Add feature"
git push

# Later, just press Ctrl+R and type:
Ctrl+R
git c
# McFly shows: git commit (at top, as it's most used in this context)

Ctrl+R
gp
# McFly shows: git push (learns your patterns)

# When in your project directory:
Ctrl+R
npm
# McFly suggests: npm install, npm start, npm test

# When in a different project directory:
Ctrl+R
npm
# McFly suggests different npm commands based on what you usually do there

# The learning is context-aware per directory

# You used a complex command weeks ago:
ffmpeg -i input.mp4 -c:v libx265 -crf 23 output.mp4

# Recover it without remembering exact syntax:
Ctrl+R
ffmpeg
# McFly shows your previous ffmpeg commands ranked by relevance

# Or search for partial pattern:
Ctrl+R
265
# Finds the HEVC encoding command

# Docker commands with context
Ctrl+R
docker run
# Shows your frequently used docker commands

# Kubernetes operations
Ctrl+R
kubectl apply
# Shows your kubectl patterns

# Python development
Ctrl+R
pytest
# McFly learns your testing patterns

# Set McFly data directory
export MCFLY_HOME="$HOME/.config/mcfly"

# Configure history file location
export HISTFILE="$HOME/.history"

# Control number of results shown
export MCFLY_RESULTS=20

# Add to ~/.bashrc or ~/.zshrc
# These variables control McFly's behavior and data storage

# For Bash, customize in ~/.bashrc:
eval "$(mcfly init bash)"

# For Zsh, customize in ~/.zshrc:
eval "$(mcfly init zsh)"

# For Fish, customize in ~/.config/fish/config.fish:
mcfly init fish | source

# Keybinding customization (shell-specific)
# Bash: Use bind command
# Zsh: Use bindkey command
# Fish: Built-in keybinding setup

# McFly automatically imports your existing shell history on first run

# If you want to re-import or migrate:
mcfly import

# This helps bootstrap the machine learning model with your past commands
# After import, McFly learns patterns from your entire history
