Google Gemini CLI Integration

Quick Setup

1. Create Gemini config directory

mkdir -p ~/.gemini

2. Download nomoji rules

curl https://nomoji.dev/api/template/default/generic -o ~/.gemini/nomoji-rules.md

3. Create config file

cat > ~/.gemini/config.json << 'EOF'
{
  "systemInstructions": {
    "include": ["~/.gemini/nomoji-rules.md"]
  }
}
EOF

4. Done!

Gemini will now follow emoji-free guidelines in all interactions

How It Works

When configured, Gemini CLI will:

Follow emoji-free guidelines in all code generation
Avoid emojis in console output, documentation, and comments
Use professional language in all generated content
Respect context-specific rules (logging, CLI output, commits)

Project-Specific Configuration

Configure nomoji rules per project:

# In your project directory
mkdir -p .gemini
curl https://nomoji.dev/api/template/default/generic -o .gemini/nomoji-rules.md

# Create project config
cat > .gemini/config.json << 'EOF'
{
  "systemInstructions": {
    "include": [".gemini/nomoji-rules.md"]
  }
}
EOF

# Commit to version control
git add .gemini/
git commit -m "Add Gemini nomoji configuration"

Presets

Strict Mode

No emojis anywhere

curl https://nomoji.dev/api/template/strict-user/generic -o ~/.gemini/nomoji-strict.md

Moderate Mode

Limited emojis, balanced approach

curl https://nomoji.dev/api/template/moderate-user/generic -o ~/.gemini/nomoji-moderate.md

Relaxed Mode

Emojis in UI only

curl https://nomoji.dev/api/template/relaxed-user/generic -o ~/.gemini/nomoji-relaxed.md

Usage Examples

Generate Code

gemini "Create a Node.js Express server with error handling"

Output will be professional with no emoji decoration

Generate Documentation

gemini "Create a README for my CLI tool"

Clean markdown without emojis

Code Review

gemini "Review this file for best practices" --file server.js

Professional feedback without emoji decoration

Troubleshooting

Rules Not Applied?

Check config file exists:ls -la ~/.gemini/config.json
Verify rules file is readable:cat ~/.gemini/nomoji-rules.md
Test with explicit system prompt:gemini --system-prompt "$(cat ~/.gemini/nomoji-rules.md)" "test prompt"

Emojis Still Appearing?

Download strict preset:

curl https://nomoji.dev/api/template/strict-user/generic -o ~/.gemini/nomoji-rules.md

Shell Aliases

Add convenience commands to your .bashrc or .zshrc:

# Update nomoji rules for Gemini
alias gemini-nomoji-update='curl -s https://nomoji.dev/api/template/default/generic -o ~/.gemini/nomoji-rules.md && echo "✓ Nomoji rules updated"'

# Gemini with strict emoji enforcement
alias gemini-strict='gemini --system-prompt "$(cat ~/.gemini/nomoji-strict.md)"'
