termlog

Paste a terminal session into a chat or a doc and you paste everything: colour codes, progress bars that rewrote themselves a hundred times, and — too often — the API key that scrolled by in the middle. termlog cleans a raw session into shareable markdown in one local pass:

1. ANSI removal — CSI, OSC, and two-character escape sequences are stripped, and every removal is counted

2. Carriage returns — each line keeps only what followed its last \r, so a progress bar collapses to its final state

3. Trailing whitespace — trailing spaces and tabs stripped

4. Redaction (on by default) — private-key blocks, AWS access key ids, GitHub tokens, Bearer credentials, and key = value secrets are replaced with [REDACTED:<kind>] markers, applied in that pattern order and counted per kind

5. Blank lines — runs of 3+ newlines collapse to exactly 2, and blank lines at the edges are trimmed

The result is the cleaned text in a ```console fence, the redaction counts, and line statistics. Pure local text transform: no network, no configuration.

CLI

npx @reneturcios/termlog clean --input session.log
npx @reneturcios/termlog clean --input session.log --no-redact
npx @reneturcios/termlog --version

The input file is read as UTF-8 and the output object is printed as JSON. Exit codes: 0 on success, 1 on a runtime error (including an unreadable input file), 2 on a usage error.

Tools

• clean_terminal_log — Turn a raw terminal session into clean, shareable Markdown.

  • text (string, required) — the raw terminal session text

  • redact (boolean, optional, default true) — apply secret redaction

  Returns {markdown, redactions, stats}: the fenced cleaned text, the per-kind redaction counts (kinds with a count above zero, in pattern order), and {input_lines, output_lines, ansi_sequences_removed, total_redactions}.
