mix lemon.send (lemon_channels v0.1.0)

Send a Telegram or Discord notification from shell scripts, cron jobs, and CI.

Usage:

mix lemon.send --to telegram:<chat_id> "deploy finished"
echo "RAM 92%" | mix lemon.send --to telegram:<chat_id>
mix lemon.send --to telegram:<chat_id>:<thread_id> --subject "[CI]" --file report.txt
mix lemon.send --to discord:<channel_id> "deploy finished"
mix lemon.send --account work --to discord:#ops "deploy finished"
mix lemon.send --to discord:#ops --thread deploys "deploy finished"
mix lemon.send --to discord:#ops --reply-to 123456789 "deploy finished"
mix lemon.send --to discord:<channel_id> --attach report.txt "artifact ready"
mix lemon.send --dry-run --to discord:<channel_id> --attach report.txt "artifact ready"
mix lemon.send --account work --list telegram

Targets are intentionally limited to Telegram and Discord for now. --account selects the channel account id for delivery and known-target lookup. --thread / --topic sets the thread or topic separately from the target. --reply-to replies to an existing platform message id. --file reads the message body from a file; --file - forces stdin. --attach uploads a local file and may be repeated up to 10 times; any body text becomes the caption. --dry-run validates the target/body/attachments and prints the send summary without delivery.

Default targets can be supplied through LEMON_TELEGRAM_DEFAULT_CHAT_ID, LEMON_DISCORD_DEFAULT_CHANNEL_ID, and optional *_DEFAULT_THREAD_ID vars.
