Install

NOTE for now t-rec depends on imagemagick, but this is going to change soon.

sh ❯ brew install imagemagick ❯ cargo install -f t-rec

NOTE -f just makes sure the latest version is installed

Usage

sh ❯ t-rec

or with specifying a different program to launch

sh ❯ t-rec /bin/sh

Hidden Gems

You can record not only the terminal but also every other window. There 2 ways to do so:

1) abuse the env var TERM_PROGRAM like this: - for example lets record a window 'Google Chrome' - make sure chrome is running and visible on screen

sh ❯ TERM_PROGRAM="google chrome" t-rec tmp path: "/var/folders/m8/084p1v0x4770rpwpkrgl5b6h0000gn/T/trec-74728.rUxBx3ohGiQ2" Press Ctrl+D to end recording [src/window_id.rs:122] window_owner = "Google Chrome 2"

this is how it looks then: demo-chrome

2) use the env var WINDOWID like this: - for example let's record a VSCode window - figure out the window id program, and make it - make sure the window is visible on screen - set the variable and run t-rec

```sh ❯ t-rec --ls-win | grep -i code Code | 27600

set the WINDOWID variable and run t-rec

❯ WINDOWID=27600 t-rec

tmp path: "/var/folders/m8/084p1v0x4770rpwpkrgl5b6h0000gn/T/trec-77862.BMYiHNRWqv9Y" Press Ctrl+D to end recording

```

this is how it looks then: demo-vscode
