Log Viewer

v1.0.0·Added in 1.0.0

A streaming log console for 100.000 lines: level colors, level and text or regex filters, follow the tail, ANSI colors and JSON details.

New lines stream in at the bottom and the view follows them. Scroll up (wheel, finger, scrollbar or keys) and following pauses by itself: a pill at the bottom counts the new lines (12 new lines) and a tap on it, the End key or scrolling back to the very end follows again; the follow toggle and the Live / Paused badge in the footer show the state. Type in the search to hide the lines that do not match (case and diacritics are ignored), or turn on the .* toggle for a regular expression (an invalid one is marked and filters nothing); in highlight mode every line stays, hits are marked and Enter / Shift+Enter or the arrows step through them. The level chips turn levels on and off and show their counts. Click, tap or press Enter on a line with details to open its JSON tree under it (the stream pauses so it stays put). The toolbar wraps lines, shows or hides the time, and the ⋯ menu copies the visible lines, downloads everything as a dated .log file or clears the buffer; on a narrow viewer wrap and time move into that menu, and below 768px it opens as a bottom sheet while the chips scroll sideways. The log body is one Tab stop: Up and Down move a focus row, Page Up / Page Down jump a page, Home goes to the first line, End to the newest, Escape drops the focus row (screen readers hear each focus row as it moves), and Ctrl+F / ⌘F inside the viewer jumps to its search (searchShortcut adds a global key). Lines over 10.000 characters are cut with a Show all button; with maxLines reached the oldest lines drop and the footer says how many.
