About

Flowsheet project example, showing several expense nodes and a node showing their sum

A flowchart/spreadsheet hybrid, where connections are front-and-centre, rather than tabular cells.

Coming from Spreadsheets, instead of Cells, we have both Nodes, and Links. Links have a formula associated to them, that can manipulate the incoming and destination data.

Nodes primarily hold data, and can be a few different types. Currently these include:

  • Switch (Boolean / On-Off)
  • Integers (Whole Numbers)
  • Decimals (Floats, Real numbers)
  • Percentages (Same as Decimals, but controlled with a slider between 0% and 100%)
  • Text (Strings)
  • Button (Same as Switch, but needs to be held down by the user to be on/true)

There is an EDIT mode, where you can add nodes and links, and set the initial values of nodes, and the formulae of links. There is a STYLE mode, where you can set how the nodes and links look. And there is a TEST mode, where you can try out your flowsheet without accidentally changing anything.

There is a scripting language you can use in the console.

Roadmap

There are still some pretty fundamental features that are not yet implemented. These include:

  • Undo/Redo of actions
  • Resizing the sheet
  • Grouping nodes and moving them together
  • Exporting flowsheets to html/css/js (Maybe?)
  • Datetime Node types
  • Enum Node types
  • Some Collection Node types (Arrays?) - Not sure yet what this would look like
