Install

You need Rust. On Windows you also need Windows 10 version 1809 or newer, which is when ConPTY arrived.

git clone https://github.com/Nuu-maan/ttysvg
cd ttysvg
cargo install --path .

That puts ttysvg on your PATH.

To try it without installing, use cargo run -- in place of ttysvg in any command in these docs:

cargo run -- record --out demo.svg -- powershell -NoLogo

Checking it worked

ttysvg --help
ttysvg themes

ttysvg themes prints every built in theme with its palette drawn in your terminal, which is also the quickest way to confirm your terminal is reporting true color correctly.

Platform notes

Windows. ConPTY is used directly, so there is nothing else to install. If you are on a build older than 1809 the pseudo console does not exist and there is no fallback.

macOS and Linux. A normal pty is used through the same code path. Everything after the terminal parser is platform independent, so tapes written on one platform work on another once you change the shell line.
