Notifications
Mera can tell you when long-running work finishes — with a local sound, an email, and/or a message to a Zulip team-chat channel (optionally with captured output, timing, and file attachments). Three functions are exported:
| Function | Purpose |
|---|---|
bell() | Play a short local sound (no configuration needed). Pick from 19 bundled sounds by name or number — bell(:gong), bell(14), bell(:list) — or set a default in ~/.mera.toml. |
notifyme(...) | Send an email and/or Zulip message, optionally with attachments, captured output, timing, and exception details. |
timed_notify(name, block) | Run block, measure its wall-clock time, and send the result via notifyme. |
Quick start
using Mera
bell() # local sound when something finishes
bell(:gong) # …or pick one: bell(:list) shows all 19
notifyme("Calculation finished!") # email and/or Zulip (after one-time setup)notifyme sends to whatever you have configured in ~/.mera.toml — an email address, a Zulip bot, or both. With neither configured it does nothing harmful, so bell() works out of the box and notifyme becomes active once you fill in the file. Run mera_config_example() to print a template. See Setup & Usage for configuration and all options, and Examples for complete Mera workflows and troubleshooting.
bell() plays a bundled sound via your audio device. Email requires the command-line mail client to be installed, which is uncommon on Windows. The package itself is tested on Windows (see the CI matrix on the home page); the notification channels are developed and used on Linux and macOS, and the email path in particular is untested there.
