Mellow

Mellow is a programming language that can be used to create music on the fly.

Status

Currently in a very primitive phase. Going forward, I plan to rewrite everything and move it into a web page so live updates can work.

Requirements

• Go (see go.mod for version)
• An available audio output device (obv!)

User Instructions

Two test files are already included:

• test.me
• test2.me

To try them, use:

./Mellow test.me
./Mellow test2.me

You can also modify the test files, or create your own .me files.

Files

• parser/: converts source text into AST nodes
• runtime/: hot-reload runtime (broken due to how file editors work :<) and scheduler lifecycle
• scheduler/: loop scheduling and playback triggering
• audio/: audio engine and notes
• ast/: AST types

Current Syntax

This is the only command for now.

loop note <NOTE> every <DURATION> ms

<NOTE> can be:

• C4
• D4
• E4
• F4
• G4
• A4
• B4

<DURATION> is time in milliseconds. Examples: 1000 ms, 100 ms, 50000 ms.
