Metronome

metronome.mov

(Put the sound on 😊)

Background

• I wanted to build out a metronome on the command line so I didn't have to rely on Google's metronome
• I used the Go beep package to output sound
• I created a Homebrew tap for easy installation of the metronome package

---

First install instructions:

• brew tap madeleinesmith/metronome && brew install metronome

---

How to release new version and update local package:

Releasing new version:

• Tag code using git tag -a v1.0.0 -m "version 1.0.0"
• Push tag with git push origin v0.2.0
• Create a new release on GitHub for that tag
• Copy the link of the tar.gz file on GitHub
• Change the url line of homebrew-metronome repo to be this
• And also update the sha256 line by running shasum -a 256 xxxxxxx.tar.gz on the downloaded tar file (above)
• Commit and push the homebrew-metronome repo with these edits

Updating the local package:

• Run brew update && brew upgrade metronome

---

Usage instructions

When using the Brew package run:

• metronome -beats-per-minute=a -beats-per-bar=b -subdivisions=c,d,e,f

e.g.

• metronome -beats-per-minute=15 -beats-per-bar=4 -subdivisions=4,4,4,7

If running locally use:

• go run main.go -beats-per-minute=a -beats-per-bar=b -subdivisions=c,d,e,f
