A Declarative Clock in Eve
- deleted 10y ago[deleted]
- zubairq 10y agoI tried the example: draw a clock hand // Select all the clock hands hand = [#clock-hand angle length] // Eve will maintain the following objects maintain // Calculate x1, y2, x2, y2 for each hand hand := [#line, x1: 50, y1: 50, // using angle and length x2: 50 + (length * sin(angle)), y2: 50 - (length * cos(angle))] draw a clock // Select the current time [#time hours minutes seconds] // Update the SVG as the time changes maintain // Add an SVG element to the root of the DOM [#svg viewBox: "0 0 100 100", width: "300px", children: // Add a clock face at (50,50) with radius 45. [#circle cx: 50, cy: 50, r: 45, fill: "#0B79CE"] // Add the hours hand [#clock-hand angle: 30 * hours, length: 30, stroke: "#023963"] // Add the minutes hand [#clock-hand angle: 6 * minutes, length: 40, stroke: "#023963"] // Add the seconds hand [#clock-hand angle: 6 * seconds, length: 40, stroke: "#ce0b46"]] But I get the error: Invalid function argument (passed string) Only expressions can be arguments to functions 14| x2: 50 + (length * sin(angle)),
