termcast

This module uses Asciinema to: - Compose terminal recordings in code - Replay recordings directly in the terminal, or generate a gif - Simulate human keystrokes and terminal output - Execute any commands in any container, and make it look like a human did it interactively - Ask an AI to imagine a terminal session, and add it to the recording

Installation

dagger install github.com/shykes/daggerverse/termcast@v0.4.0

wait() 🔗

Simulate waiting for a certain amount of time, with no input or output on the temrinal

Return Type

Arguments

Name	Type	Default Value	Description
ms	Integer !	-	wait time, in milliseconds

Example

dagger -m github.com/shykes/daggerverse/termcast@4f1667dcc120c6a6fddc956cc0d1f79ab97881bc call \

exec() 🔗

Simulate a human running an interactive command in a container

Return Type

Termcast !

Arguments

Name	Type	Default Value	Description
cmd	String !	-	The command to execute
simple	Boolean	false	Toggle simple mode. Enabling simple mode is faster and more reliable, but also less realistic: the recording will print the final output all at once, without preserving timing information. Disabling mode is more realistic: the timing of each byte is preserved in the recording; this requires building a binary (which is slow) and injecting it into the target container (which could break).
