Highlighting Code

This example demonstrates how to create synchronized highlights across multiple elements using the Bylight library in Colight.

First, let's import the necessary libraries and define our sample text:

import colight.plot as Plot

rhyme = """Roses are blue,
Violets are red,
In this rhyme's hue,
Colors are misled!"""

Use the Plot.bylight function to highlight specific words in our text:

Plot.bylight(rhyme, ["blue", "red", "Colors", "misled!"])

Traceback (most recent call last):
  File "/home/runner/work/colight/colight/packages/colight-prose/src/colight_prose/executor.py", line 139, in execute_block
    result.value = eval(block._eval_code, self.env)
                   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

    import colight.plot as Plot
    ^^^^^^^^^^^^

Animated Highlighting

We can create an animated version that highlights each word in sequence. Plot.Frames creates a reactive variable that we access via $state.frame. In this example we hide the slider.

Plot.Frames(
    [
        Plot.js("`frame: ${$state.frame}`") & Plot.bylight(rhyme, pattern)
        for pattern in rhyme.split()
    ],
    fps=2,
    slider=False,
)
