Installation

The current quick installer supports x86-64 Linux with glibc 2.34 or newer:

curl -fsSL https://dewy-lang.org/install.sh | bash

It installs the verified native dewy/udewy pair and its matching library under ~/.dewy; Python is not needed. Open a new terminal and check the installation:

dewy --version

The native compiler is still a development version with some hosted-parity gaps. From a source checkout, the hosted compiler remains available with Python 3.14 or newer:

python -m dewy program.dewy

The browser playground is useful for small experiments without a local installation. It currently runs µDewy, Dewy's bootstrap subset, rather than every construct described in this book.

These are current tooling constraints, not intended language restrictions. See the implementation appendix for context and the website's installation page for up-to-date platform details.
