Pre-built Binaries

Download from releases for Linux, macOS, Windows (amd64/arm64).

See INSTALL.md for detailed installation instructions and GORELEASER_SETUP.md for building releases.

Configuration

Quick Setup (Recommended)

ctw init

This verifies your credentials and writes a config file with an env reference.

Config File (TOML)

Default locations:

• macOS/Linux: ~/.config/ctw/config.toml
• Windows: %APPDATA%\\ctw\\config.toml

Example:

[auth]
bearer_token = "env:BEARER_TOKEN"

[http]
user_agent = "ctw/0.2"
timeout = "15s"
retry = 3

[output]
pretty = false

[stream]
backoff_max = "2m"

See config.example.toml for a ready-to-copy template.

Precedence

Automation Examples

Real-Time Monitoring

# Monitor keywords and pipe to processing
ctw watch --keyword "golang" --auto-setup | grep "tutorial"

# Multi-keyword brand monitoring
ctw watch --keyword "@YourBrand" --keyword "YourProduct" --auto-setup --show-user

# Stream with complex rules
ctw stream rules add --value "bitcoin OR ethereum lang:en -is:retweet"
ctw stream

Data Collection & Analysis

# Search and extract with jq
ctw search recent --query "AI ethics" --param "max_results=100" \
    | jq -r '.data[] | [.author_id, .text] | @csv'

# Get tweet counts over time
ctw counts recent --query "climate change" --granularity day

# Monitor user activity
ctw timelines user --user-id 123 --param "max_results=50"

Content Publishing

# Simple tweet
ctw tweets create --text "Hello from automation"

# Tweet with media
MEDIA=$(ctw media upload --file chart.png --category tweet_image | jq -r '.media_id_string')
ctw tweets create --text "Daily metrics" --media-ids "$MEDIA"

# Scheduled via cron: 0 9 * * * /usr/local/bin/post_daily_update.sh

User Management

# Lookup users
ctw users lookup --usernames "github,golang,docker"
ctw users lookup --ids "123,456,789"

# Manage relationships
ctw users follow --source-id YOUR_ID --target-id 123
ctw users block --source-id YOUR_ID --target-id 456

Engagement Automation

# Like tweets matching criteria
ctw search recent --query "open source" --param "max_results=10" \
    | jq -r '.data[].id' \
    | xargs -I {} ctw likes add --user-id YOUR_ID --tweet-id {}

# Retweet quality content
ctw retweets add --user-id YOUR_ID --tweet-id 1234567890

# Manage bookmarks
ctw bookmarks add --user-id YOUR_ID --tweet-id 9876543210
ctw bookmarks list --user-id YOUR_ID

Scripting Patterns

# Error handling with exit codes
if ctw tweets create --text "test"; then
    echo "Posted successfully"
else
    echo "Failed with code $?"
fi

# Loop through results
ctw search recent --query "golang" | jq -r '.data[].text' | while read -r tweet; do
    echo "Processing: $tweet"
done

# Combine multiple operations
USER_ID=$(ctw users lookup --usernames "twitter" | jq -r '.data[0].id')
ctw timelines user --user-id "$USER_ID"

How It Works

ctw is a thin CLI wrapper around the Twitter v2 API. It handles:

• Authentication - Bearer token management
• HTTP - Configurable client with rate-limit tracking
• JSON - Type-safe request/response handling
• Errors - Proper exit codes and error messages
• Streaming - Real-time filtered stream processing

All commands output JSON to stdout and logs/errors to stderr, making it perfect for Unix pipelines and automation scripts.

Project Structure

cmd/ctw/             # CLI commands (Cobra)
internal/client/     # HTTP client with auth and rate-limits
internal/tweet/      # Tweet services (publish, search, stream, likes, etc.)
internal/users/      # User services (lookup, follow, block)
internal/media/      # Media upload (chunked upload for large files)
internal/dm/         # Direct message services
script/sh/           # Shell script examples and testing utilities

Development

Run tests:

go test ./...

Tests use httptest.Server mocks - no live API calls required.

Build locally:

make build        # Builds to bin/ctw
make install      # Installs to /usr/local/bin
make deb          # Creates .deb package

Contributing:

• Follow the service pattern: accept context.Context, return typed structs + client.RateLimitSnapshot
• Keep CLI commands thin - parse flags, call service, print JSON
• Add tests using httptest.Server helpers
• Update documentation when adding features

Issues & Contributions:

• Report bugs or request features via GitHub Issues
• PRs welcome -- small, focused changes are easiest to review

API Rate Limits

Twitter API has rate limits. ctw tracks and reports rate-limit headers:

ctw search recent --query "test" 2>&1 | grep "Rate Limit"

Rate limits vary by endpoint. See Twitter's documentation for details.
