fix(shell): two parse errors — missing ';' before '}', and shell logic inside an array literal - #334
Conversation
…c inside an array literal
Two files, two distinct parse failures.
nick-shells/shell/modules/prompt.sh:30 — 'precmd() { PS1="..." }' needs a ';' before the closing brace; without it the whole file fails to parse.
nerdsafe-restart/run-constrained.sh:163 — '${HOME}/.asdf && --volume=...' sat INSIDE the NERDCTL_ARGS=( ... ) array literal. Conditional logic is not valid there, so the array never closed and the file did not parse — meaning the container was never receiving any of these arguments. Moved out to a conditional append after the array closes, which is what the comment intended.
Note prompt.sh still reports SC2148 (no shebang). It is a sourced module, so a shebang may be inappropriate; left for separate triage rather than added blindly.
Found by an estate-wide shellcheck sweep of 5,111 tracked scripts across 375
repos: 11 files fail to PARSE (SC1073/SC1072). shellcheck stops analysing at
the failure, so everything after it in the file was never checked either.
Verified: shellcheck -S error reports 0 parse errors for the file(s) touched.

Pull Request Overview
While this PR successfully addresses the syntax errors mentioned in the title, it introduces a significant logic regression in run-constrained.sh. Specifically, a new conditional block at line 177 is redundant with existing logic (lines 180-186) and incorrectly appends arguments to the NERDCTL_ARGS array.
Because the volume flag is added after the image name, the command will fail during execution as nerdctl requires options to precede the image. Additionally, the subsequent array-slicing logic will incorrectly duplicate the image name. These issues should be resolved before merging to ensure the script functions as intended.
About this PR
- The PR introduces argument corruption in
run-constrained.sh. By appending to theNERDCTL_ARGSarray after the image name has already been set, the script violates container runtime conventions where options must appear before the image. This also breaks the fragile array-slicing logic used later in the script to insert other conditional volumes.

Suggestion: Adding a ShellCheck directive helps editor and CI tools understand the intended shell dialect for this module. Since this is a Zsh-compatible prompt module, ensure the directive matches the intended interpreter.# shellcheck shell=bash
line 1⚪ LOW RISK
Nitpick: Referenced quality issue for shell dialect identification.
Test suggestions
- Verify 'prompt.sh' loads without error in a Zsh environment.
- Verify 'run-constrained.sh' executes without syntax errors in Bash.
- Verify that when '${HOME}/.asdf' exists, the volume argument is correctly inserted into the nerdctl command before the image name.
- Verify that the container image name is not duplicated when the '.asdf' directory exists.
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify 'prompt.sh' loads without error in a Zsh environment.
2. Verify 'run-constrained.sh' executes without syntax errors in Bash.
3. Verify that when '${HOME}/.asdf' exists, the volume argument is correctly inserted into the nerdctl command before the image name.
4. Verify that the container image name is not duplicated when the '.asdf' directory exists.

🔴 HIGH RISK
This conditional append is redundant and introduces a logic error. The logic for mounting the '.asdf' volume is already implemented in the block at lines 180-186. Adding it here at line 177 appends the --volume flag after the $IMAGE_NAME (which was added at line 173), violating the requirement that options precede the image name in nerdctl. Furthermore, this causes the subsequent slicing logic to malfunction, resulting in a duplicated image name and a malformed command.
Consider refactoring the script to push $IMAGE_NAME to the array at the very end (after all conditional logic) so that flags can be added using simple += syntax without brittle array slicing.

Remove the duplicate .asdf argument construction.
When ${HOME}/.asdf exists, the append places --volume=... after $IMAGE_NAME. The conditional rebuild then preserves the original image and adds a second $IMAGE_NAME. The volume is therefore after the image and may be treated as a container command argument, not a nerdctl option. Keep one .asdf construction only.
