Live logs and adaptations¶

Live logs¶

A chat beside a stream, a build log, a feed of events: any box the page marks role=log or aria-live, or any scroll box the page keeps appending rows to, is a live log. Noctiluca knows it from those constructs alone, never from the site. New rows arrive within a fraction of a second, and only they are read: the rest of the page is not read again.

The log shows its newest entries, in its own box, and follows them.
{ scrolls it up. It then holds still while new entries come. } scrolls it down, and at its end it follows again.
Each entry keeps its colours (an author's name) and its small pictures (badges, emotes).
A chat's input is an ordinary field: f and its hint, type, Enter, then its Send button.

Terminal adaptations¶

A page is drawn as Chrome lays it out, with a few named rules that make it read better in cells. Each rule is about constructs, never about a site, and each can be switched off.

Rule	What it does	Default
`decorative-images`	Drops spacers, tracking pixels, and icon-sized pictures marked decorative (`alt=""`, `aria-hidden`)	on
`inline-pictures`	Keeps small pictures (emotes, badges) in their line	on
`cap-pictures`	Caps a picture's height; what is under it moves up	on
`captions`	An `Image: …` line under a picture with alt text and no caption	on
`icon-buttons`	Shows every button, icon-only ones too, as `[ label ]` from its name	on
`snap-grids`	Snaps a grid's columns to the cells, with fewer columns when they would be too narrow	on
`collapse-nav`	On a narrow terminal (under 100 columns), a navigation or sidebar becomes one row of its links	on
`collapse-gaps`	Rows blank across the whole page (an empty ad slot, a hidden menu, a spacer) collapse to one blank row	on
`text-over-pictures`	Draws a picture of text (a heading or button image, a banner) as its text	off: it changes meaning
`live-tail`	A live log shows its newest entries unless you scrolled it up	on
`page-colors`	Keeps the page's saturated text colours (a red label, a chat name), readable on your terminal; greys follow your terminal's own colour. Off, the page's own colours: on a light terminal as the page wrote them, on white; on a dark one with their lightness turned over (dark text reads light, a red stays red), on black	on
`bandwidth`	Lowers a video's frame rate and picture tier when the terminal is short of bandwidth	on

a (Alt+A in the plain keys) toggles between the adapted and the faithful projection, with no rule at all.
? (Alt+I), or going to about:noctiluca, opens the about page: the version, the browser, the rules and which are on, and the codecs the browser says it plays.
--adapt=-decorative-images,-collapse-nav switches rules off for one run, and --adapt=+text-over-pictures switches one on. --no-adapt switches every rule off.
In the config, [adapt] sets each rule by its name:

[adapt]
collapse-nav = false
text-over-pictures = true
