Highlight & Gag Sets

Highlight and gag rules multiply fast. Keep them as data:

local highlights = {
    { pattern = "tells you",        color = rune.style.cyan },
    { pattern = "You are hit",      color = rune.style.red },
    { pattern = "levels up!",       color = rune.style.green },
    { pattern = "The sun rises",    color = rune.style.yellow },
}

for _, h in ipairs(highlights) do
    rune.trigger.contains(h.pattern, function(m, ctx)
        return h.color(ctx.line:clean())
    end, { group = "highlights" })
end

local gags = {
    "The barkeep polishes a glass",
    "A gentle breeze blows",
    "drops a piece of lint",
}

for _, g in ipairs(gags) do
    rune.trigger.contains(g, nil, { gag = true, group = "gags" })
end

How it works

• A trigger handler that returns a string rewrites the line; here, the whole line is re-colored. Later triggers match against the rewritten text. See Triggers.
• A nil action with gag = true silences the line with no handler at all.
• The groups are the off switch: /group gags off when you suspect you’re missing something, /group highlights off for screenshots.

Variations

Highlight only a word, not the line, by rewriting with a targeted replace:

rune.trigger.contains("gold coins", function(m, ctx)
    return (ctx.line:clean():gsub("gold coins",
        rune.style.yellow("gold coins")))
end)

Gag but count, to silence spam without losing information:

local swings = 0
rune.trigger.contains("You swing at", function()
    swings = swings + 1
    rune.ui.refresh_bars()
    return false
end, { group = "gags" })

rune.ui.bar("swings", function() return "swings: " .. swings end)
rune.ui.layout({ bottom = { "swings", "input", "status" } })

The layout line is required: a bar renders only if a layout dock names it.
