Scenario:

Try APT or Homebrew for clean demos; curl | bash shows shell-installer output.

Scenario change queued. It will apply on the next Start or Reset.

Window style:

Accepted styles: Auto, macOS, Windows, or Linux.

Display mode:

Windowed stays embedded; Fullscreen or Popup is better for capture.

Line pace: {{ paceLabel }}

Use 1.00x for normal demos; 0.50x slows walkthroughs, 2.00x speeds loops.

Network profile:

Stable is smooth; throttled or flaky profiles make retries easier to see.

Warnings & jitter:

Turn off for clean success streams; turn on with flaky or throttled profiles.

Auto-scroll:

Turn off before scrolling back; exports still use retained history.

Max log lines:

Keep 80-600 lines; raise before recording long loops.

lines

Packages per loop:

Use 3-6 for short clips; 9-18 for busier terminal loops.

packages

Random seed:

Enter up to 10 digits; leave blank for a new random sequence on reset.

Timestamp display:

Enable when screenshots or demos need line-by-line timing context.

Terminal installer output is a staged story: dependency checks, download lines, progress updates, warnings, post-install messages, and final status all appear in one fast-moving stream. A believable simulated session helps training material, product demos, support articles, classroom labs, and screen recordings show that flow without changing a real machine.

Different installer families have different rhythms. APT and DNF runs usually emphasize repositories, package lists, dependency resolution, and configuration triggers. Homebrew talks in formulae and bottles. Winget and Chocolatey use Windows-style package identity and validation language. npm, pip, and Cargo focus on registries, dependency graphs, build or wheel steps, and installed commands. A shell installer has its own bootstrap feel, with download, verification, and setup lines packed together.

Use simulated output as presentation material, not operational proof. The stream can make a tutorial or rehearsal easier to follow, but it cannot validate repository health, network reachability, checksum safety, shell-script trust, disk permissions, or real install speed on a host.

How to Use This Tool:

Choose the installer family that matches the audience: APT, Homebrew, Winget, DNF, Pacman, Chocolatey, npm global, pip install, Cargo, or Shell installer.
Set the visual style and display mode before recording. Windowed mode keeps the controls nearby, fullscreen is better for clean capture, and the popup view isolates the terminal surface.
Pick a Network profile. Stable datacenter makes the run calm, home Wi-Fi adds ordinary variation, throttled VPN slows the stream, and unstable hotspot creates the most visible stalls and retry-style warnings.
Adjust Line pace, Packages per loop, Warnings & jitter, timestamp display, and the maximum retained log length.
Enter a numeric seed when the same run must be repeated for another take. Leave the seed blank when variety is more useful than repeatability.
Press Start, pause at the moment you want to capture, then review the terminal replay, package ledger, event ledger, progress trace, or JSON view before exporting.

For a clean first pass, use 3 to 6 packages per loop, leave warnings off, and keep the pace near normal speed. Add noise only after the basic terminal story is easy to read.

Interpreting Results:

Progress is the simulated completion percentage for the current loop. It is derived from the generated package queue and active stage, so it should be read as a presentation cue rather than a real package-manager estimate. Average speed and Latency are sampled profile values, not measurements from a live mirror or registry.

Loop # shows how many full generated queues have completed in the current session.
Retries rises when warning or error-style lines are injected. It does not prove a real download failure.
Package Ledger is the easiest place to confirm package names, stages, sizes, hosts, speeds, latency samples, and final status.
Event Ledger is the best audit view for the exact retained log sequence, including time, loop, stage, package, message, and progress.
JSON preserves settings and retained events for reuse, but it still describes a simulated session.

If a long run matters, raise the retained-line limit before recording. The terminal view, ledgers, copied CSV, downloaded CSV, DOCX export, and JSON export all reflect the retained event history.

Technical Details:

The session is modeled as a queue of package-like work items. Each item moves through prepare, download, install, configure, and finish stages. Scenario presets supply the command style, package naming, host naming, and line families, while the active network profile controls the pace and the likelihood of warning-style messages.

Formula Core:

Loop progress is based on completed packages plus the active package's current stage percentage:

loop progress = 100 \times \frac{completed packages + \frac{active package percent}{100}}{total packages}

Rule Core:

Build a queue from the selected scenario and package count.
Generate the prompt, command, prelude lines, package-stage lines, warning lines, and completion lines in scenario order.
Sample download speed and latency from the selected network profile for the visible metrics.
Use the numeric seed, when present, to make package order, host choices, timing variation, and warning placement repeatable for the same settings.
Clamp the retained history to the selected maximum log length, then derive the terminal, ledgers, chart, CSV, DOCX, and JSON outputs from that retained history.

Installer stage bands
Stage	Package progress band	Visible cues
Prepare	`0% to < 12%`	Repository metadata, dependency checks, package selection, or registry setup.
Download	`12% to < 38%`	Fetch lines, transfer sizes, hosts, speeds, checksums, stalls, or retry-style messages.
Install	`38% to < 68%`	Unpacking, pouring, compiling, wheel work, binary placement, or install progress.
Configure	`68% to < 96%`	Post-install hooks, triggers, path notes, scriptlets, caveats, or environment setup.
Finish	`96% to 100%`	Cleanup, verification, summary lines, and loop completion.

Network profile ranges
Profile	Base delay	Speed range	Latency range	Typical reading
Stable datacenter	420 ms	18 to 92 MB/s	18 to 95 ms	Fastest, calmest stream with fewer warning cues.
Home Wi-Fi	560 ms	7 to 42 MB/s	45 to 190 ms	Ordinary variation for everyday tutorial footage.
Throttled VPN	780 ms	2.2 to 16.5 MB/s	120 to 420 ms	Slower stream with more visible stalls.
Unstable hotspot	920 ms	0.8 to 9.8 MB/s	220 to 980 ms	Noisiest profile, useful for retry demonstrations.

Worked Examples:

Repeatable Homebrew demo:

Choose Homebrew (macOS), set 5 packages per loop, keep warnings off, and enter a seed such as 424242. The same settings and seed recreate the same general order and warning placement, which is useful when multiple recordings must match.

Noisy shell bootstrap rehearsal:

Choose Shell installer, select Unstable hotspot, and enable warnings. The terminal will show a more dramatic stream with retries, slow transfers, and verification-style lines. Use it to explain recovery language, not to endorse running a real remote script.

Short classroom screenshot:

Choose APT (Linux), set 3 packages per loop, enable timestamps, start the session, then pause during the second package. The visible prompt, command, timestamps, progress badges, and ledger rows give a compact slide-friendly example.

FAQ:

Does it install anything?

No. The generated session does not run shell commands, change the local system, contact package repositories, or inspect the host package database.

What makes a seed useful?

A seed makes the same scenario and settings replay the same generated choices closely enough for repeatable demos, screenshots, and narration takes.

Why do exported logs miss early lines after a long run?

The retained-line setting limits how many recent events are kept. Increase it before starting a long capture if the beginning of the run needs to appear in exports.

Can warning lines prove a real installer problem?

No. Warning and error-style lines are synthetic cues for demonstrations. Diagnose real installers with the actual command output from the affected system.
