- compileRules precomputes the full SGR open sequence per rule and per band;
wrap() is now pure concatenation, bandOpen() a table lookup (output bytes
unchanged, bg keeps its unvalidated white-fallback)
- claim() replaces the linear overlaps() scan: claimed spans stay sorted by
start, O(1) append on the common left-to-right sweep plus one binary search
otherwise (match-dense 200KB payload: -19% one-shot, -56% streamed)
- HighlightStream: bufferHasEsc flag skips the O(buffer) escape rescans when
neither the held text nor the chunk contains ESC, fixing quadratic rescan on
escape-free floods (plain 200KB streamed: -54%)
- applyHighlights tracks the consumed match budget incrementally instead of
two budgets.reduce() passes per text token
- ESCAPE_RE now covers DCS/APC/PM/SOS (BEL or ST terminated) and single-char
Fe escapes (DECSC/DECRC/NEL/RI/RIS, orphan ST); isIncompleteEscape holds cut
tails of the new families; split-smoke exercises every cut point through them
Rules & engine:
- 22 presets (was 11): split status into okstate/warnstate/badstate, add delop,
createop, danger, secret, level, exitcode, percent, http; status words are
case-insensitive and cover the ✓ ✔ ✅ ✗ ✘ ✖ ❌ ⚠ symbol set
- value bands: the first number in a match picks the colour
(percent: <20% red / 20-50% yellow / 50-80% light green / >=80% green)
- optional per-rule `caseInsensitive`, `category`, `bands`; load-time
`refreshBuiltinRules` upgrades untouched built-in patterns in place
Settings page:
- three-way master switch `highlightMode` (all / basic / off); `basic` runs only
the five safety+status rules and `off` empties the rule set rather than
bypassing HighlightStream (which would drop the held tail)
- category column + grouping (`highlightGroupByCategory`), per-rule hit/duration
stats (`highlightStats`, opt-in sink, snapshot once a second), theme-following
colours (`highlightThemeColors`, hue-bucket mapping onto the ANSI palette),
import/export JSON envelope, live preview through the real engine
- named rule subsets bound per host (`highlightPerHost` + `highlightProfiles`
+ `SshConnection.highlightProfileId`); empty ruleIds = every rule
Tests: new tests/hl-rules.mjs (word boundaries, case flag, negative words,
bands, import/export, preview, basic mode, categories, stats, theme colours,
profiles) + profile round-trip in tests/settings-store.mjs
