With v46 Hot, shell-dep hot-swap --bin rg atomically replaces the binary pointer in your environment’s PATH cache. The change is visible to the very next line in your script.
Instead of writing brittle which checks or embedding apt-get install commands in your scripts, shell-dep allows you to define a .shell-dep.toml file: shell dep version 46 hot
# macOS (Homebrew) brew upgrade shell-dep --fetch-HEAD sudo apt install shell-dep=46.0-hot Step 2: Verify the installation shell-dep version # Output: shell-dep 46.0-hot (commit: a7f3b2c, hot-cache enabled) Step 3: Create a test branch git checkout -b test/shell-dep-v46-hot shell-dep hot-upgrade git add .shell-dep.lock git commit -m "chore: upgrade to shell-dep v46 hot" Step 4: Run your pipeline Execute your usual build or test suite. Monitor for the new hot cache logs (they appear in green with a 🔥 emoji). Real-World Performance Gains Early adopters have reported dramatic improvements. Here’s a small sample: With v46 Hot, shell-dep hot-swap --bin rg atomically
introduces a daemon-less shared memory cache. The first time you run a command, it builds a hot manifest in /dev/shm (or a Windows equivalent). Subsequent runs are almost instantaneous. Monitor for the new hot cache logs (they
However, if you are in a highly regulated environment (finance, healthcare, federal), you may want to wait for the upcoming “Hardened” release (v46.1) which will add FIPS-compliant hashing. For everyone else—start upgrading now. Shell Dep Version 46 Hot is not just an incremental bump. It’s a fundamental rethinking of how shell dependencies should behave in modern CI/CD and development environments. The hot cache alone is worth the upgrade; add in hot swap and live security scanning, and you have a tool that finally makes dependency management as fast and seamless as it should have been from the start.
