Visualisation of organic compounds by name.

User opens index.html, draws compound name into the text field and clicks Draw.

Currently supported chemical structures are:

• Base string (metan, etan, propan, …, oktan)
• Alkyls (metyl, etyl, propyl, …, oktyl)
• Alcohols (metan-1-ol, etan-1-ol…)

These structures can be arbitrarly combined.
Implicit positioning (works metyletan as well as metyl-1-etan) is available only for alkyls.

├── p5.js – p5 library
├── sketch.js – main script
├── constants.js – conversion between string and number encoding
├── carbon.js – contains Yl and Carbon classes
├── compound.js – contains Compound class
└── addons – currently not in use

Scripts are called in following order: p5.js -> constants.js -> carbon.js -> compound.js -> sketch.js.
Algorithm starts with function drawCompound()@sketch.js, which is called after user presses button. New Compound object is created.

Represents whole compound. Compound parses input string using the function Compound.parse(). Compound stores array of Carbon objects in Compound.base. It also stores an array of Yl objects.

Represents one unit (for ex. CH3, OH…). Contains exact xy position where to be rendered.

Represents an addition to base string (alkyls and alcohols). It contains an array or Carbon objects – Yl.base.

Every class contains render function. Compound.render() calls Carbon.render(), which renders base carbons and calls Yl.render().
