📝 WalkthroughWalkthroughThe dev container now generates common English locales, applies a locale fallback for unsupported host settings, and sources a shell initialization script that displays project URLs and development commands in interactive terminals. ChangesDev container shell initialization
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The dev container adds locale generation and terminal guidance, but unsupported inherited locale settings can still produce startup warnings, including before the fallback is applied. Resolve the startup ordering and per-variable validation to meet the intended warning-free terminal behavior. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Configure the locale fallback before Bash starts.
~/.bashrc runs after Bash initialization. An invalid inherited locale can therefore produce a setlocale warning before shell-init.sh clears it. Set the fallback in the container environment or in a wrapper that runs before Bash.

Validate every locale override, not only LANG.
When LANG is valid but LC_CTYPE, LC_TIME, or LC_ALL is unsupported, line 9 skips the fallback and leaves the invalid variable in the environment. The warning can continue. When only LANG is invalid, lines 10-11 also remove a valid LC_ALL override. Check locale variables in precedence order and clear or replace only unsupported values.

Opening a terminal in the dev container printed
setlocale: cannot change locale (en_AU.UTF-8)on every command and showed nothing about where anything was.OpenSSH forwards the host's
LANGandLC_*, and the image had not generated that locale.post-create.shnow generates the common English locales before a shell ever starts, and a sourced.devcontainer/shell-init.shfalls back toC.UTF-8for any other locale the image lacks, so the warnings stop at the source rather than being hidden.The same file prints a short summary on each new terminal: where the backend is, and the commands that matter. The dev container now greets a person rather than only the creation log.
Checked here: with a locale the image lacks, the shell ends up on
C.UTF-8withLC_*cleared andlocalereports nothing; with a present locale nothing changes.Summary by CodeRabbit
