Oils 0.19.0

This is the home page for version 0.19.0 of Oils, a Unix shell. To use it,

1. Download a source tarball.
2. Build it and do a "smoke test", as described in INSTALL.

These steps take 30 to 60 seconds on most machines. After installation, see Getting Started.

The associated quality page shows test results, metrics, and benchmarks.

Download

Note: oil-$VERSION is the slow Python build, while oils-for-unix-$VERSION is the new, fast C++ build.

What's New

• Details are in the raw git change log. Not all changes affect the release tarball.
• I sometimes write a release announcement with a high-level description of changes.
