scheme.c | A Scheme interpreter base on R5RS specification | Interpreter library

I figured out the issue. I forgot to add following in my main app's info plist

Based on the posted error and the project structure, I think that the problem is how you include responsive.css. Maybe the problem is your template.

Look at this output.

Your question is not really clear. But I suspect you want copying formatting from one target row to multiple adjacent following rows. And you want expanding the ranges of conditional formatting rules too, so that the cells in the adjacent following rows also follow that rules. So the same what Excel's format painter does if you select one row, then click format painter and then select multiple adjacent following rows.

How to copy cell styles, you have got already. But why doing this that complicated? Copying cell styles form one cell to another is a one-liner: targetCell.setCellStyle(sourceCell.getCellStyle());.

Second we should copy possible row style too. The following example has a method void copyRowStyle(Row sourceRow, Row targetRow) for this.

To expand the ranges for the conditional formatting rules we need getting the rules which are applied to the cell. The rules are stored on sheet level. So we need traversing the SheetConditionalFormatting to get the rules where the cell is in range. The following example has a method List getConditionalFormattingsForCell(Cell cell) for this.

Having this we can expand the ranges of the conditional formatting rules. The following example has a method void expandConditionalFormatting(Cell sourceCell, Cell targetCell) for this. It expands the ranges of the conditional formatting rules from sourceCell to targetCell.

Complete example which shows the principle:

It's polar notation for complex numbers @. I've never found documentation for it other than the syntax but I'd guess that is in radians.

(magnitude 2@2) => 2.
(angle 2@2) => 2.

You can find the documentation for math functions in The Scheme Programming Language, Fourth Edition, Section 6.4. Numbers:

• sqrt
• sin

Records with support for functional updates are specified in SRFI 57. An implementation is provided by its original author, André van Tonder, as a portable R7RS library. Simple wrappers that can accommodate R7RS in Chez, which embraces R6RS, are available in the wild, but I will recommend a comprehensive system that does an excellent job of "vigorously shaking code it until it behaves properly", namely Akku.scm.

f is bound to a procedure that has the body of let as a body and ls as a parameter.

The following sequence works for me in Chez v9.5:

Each state update in react causes a re-render, and as your onClick toggles the editable flag, the component will re-render on each button click. If you don't want colors to be regenerated each time, you need to move that function out of the render() (for example, to the componentDidMount(), as John Ruddell suggested).
