Logs and plain text
Logs follow new content as it arrives; show only matching lines by text or regular expression, and stay smooth even with hundreds of MB.
While a step that writes a log is running, the card stays at the end and follows new content, with Live next to the title. For big files only the few hundred visible lines are read, and an update reads only what was added.
Display
Section titled “Display”- Lines wrap with a hanging indent; code, config and tables do not wrap.
- Scrolling up is never pulled back, and Back to latest appears at the bottom with a count of new lines.
- Error lines are red and warning lines amber (turn this off with Color errors & warnings).
- Under Position, choose Auto (logs and very large files stay at the end, others start from the top), End or Start.
- With Have the model fit the card on, the step writing the log puts one entry per line, each with a time and a level.
Only show
Section titled “Only show”Use Only show in Canvas display settings to display only matching lines; the number of matching lines appears next to the title.
