It supports conversion from asciicast v2 files produced by asciinema recorder. It uses Kornel Lesiński's excellent gifski library to produce optimized, high quality GIF output with accurate frame timing.

agg is a successor to asciicast2gif.
Building from source requires Rust compiler (1.56.0 or later) and Cargo package manager. You can install both with rustup.
To download source code, build agg binary and install it in $HOME/.cargo/bin
run:
cargo install --git https://github.com/asciinema/aggYou need to ensure $HOME/.cargo/bin is in your shell's $PATH.
Alternatively, you can manually download source code and build agg binary with:
git clone https://github.com/asciinema/agg
cd agg
cargo build --releaseThis produces an executable file in release mode (--release) at
target/release/agg. There are no other build artifacts so you can copy the
binary to a directory in your $PATH.
Alternatively, if you have Docker, Podman or another Docker-compatible tool installed you can use it to build agg container image. This doesn't require Rust toolchain installed on your machine.
Build the image with the following command:
docker build -t agg .Then run agg like this:
docker run --rm -it -u $(id -u):$(id -g) -v $PWD:/data agg demo.cast demo.gifIf you use Podman in root-less mode:
podman run --rm -it -v $PWD:/data agg demo.cast demo.gifIf you're interested in customization of agg or any other asciinema component to for your corporate needs, check asciinema consulting services.
