Summary

  • Removed eza: Completely removed all eza configurations, including aliases, completions, and installation logic as requested.
  • Fixed Zsh Startup Errors:
    • Updated omz-kube-ps1.plugin.zsh to use an explicit DEBUG == "true" check, preventing verbose xtrace output when DEBUG=false.
    • Added a defensive stub for _omz_register_handler in omz-git.zsh to prevent "command not found" errors when Oh My Zsh is not fully loaded.
  • Ubuntu Compatibility: Added conditional aliases for fd (fdfind) and bat (batcat) in dot_aliases to handle Ubuntu-specific package naming.
  • Documentation: Updated the Zsh startup error investigation report with the resolution details.

Test Plan

  • Ran make test-linux (All 6 tests passed).
  • Manually verified that DEBUG=false does not trigger set -x.
  • Verified that sourcing omz-git.zsh no longer produces command errors for missing handlers.
  • Confirmed eza removal via codebase-wide grep.

Summary by CodeRabbit

  • Bug Fixes

    • Fixed Zsh startup errors on Ubuntu 22.04 and tightened debug trigger to avoid unintended tracing
  • Chores

    • Removed eza completions/support and stopped installing that completion
    • Added Ubuntu compatibility fallbacks for alternate command names (fdfind→fd, batcat→bat)
    • Added a defensive no-op for a missing Git handler; switched Prezto prompt to "spaceship"
    • Improved init logic to prefer local binaries and adjusted pre-setup fpath handling
  • Documentation

    • Added investigation, plans, designs, verification, and cleanup notes
  • Tests

    • Added a Bats health-check suite and Makefile target to verify interactive Zsh startup, theme, aliases, completions, and RPROMPT behavior

📝 Walkthrough

Walkthrough

This PR remediates Zsh startup failures on Ubuntu 22.04 by removing the eza tool entirely, adding conditional aliases for fd and bat to match Ubuntu package names, tightening the DEBUG environment check in an Oh My Zsh plugin, adding a defensive no-op stub for a missing Oh My Zsh function, and removing dead Prezto installation code.

🐰 I nudged the shell with careful paws,
removed a tool that caused the flaws,
aliased names to bridge the gaps,
added stubs to stop the claps,
now startup hums with happy laws.

Code Review

This pull request addresses Zsh startup errors on Ubuntu 22.04 by refining debug triggers, adding compatibility aliases for fd and bat, and providing defensive stubs for missing internal functions. It also removes all eza configurations and associated installation logic. The review feedback highlights the need for sequential task numbering and accurate replacement logic in the documentation, and suggests using idiomatic Zsh syntax for command existence checks.

The replacement logic described in this plan for run_once_before_20_install_prezto.sh is incorrect. If followed literally, it would leave a broken if block in the script. The implementation in this pull request is correct, but this plan document should be updated to accurately reflect the change and prevent errors if used by an automated agent.

This alias file appears to be zsh-specific, given its use of setopt and global aliases. For checking if a command exists, you can use the more idiomatic zsh conditional (( $+commands[command_name] )) instead of command -v. This would make the code slightly cleaner and more consistent with zsh scripting practices.

if (( ! $+commands[fd] && $+commands[fdfind] )); then
  alias fd='fdfind'

if (( ! $+commands[bat] && $+commands[batcat] )); then

⚠️ Potential issue | 🟡 Minor | ⚡ Quick win

Fix heading level increments to satisfy markdownlint (MD001).

Line 13 starts at ### after a top-level #, and peer task headings follow the same pattern. This triggers the lint warning and makes task sections appear nested instead of sibling sections.

GNU Make parse-time conditional ifdef ifndef evaluation order

💡 Result:

GNU Make evaluates all parse-time conditionals (ifdef, ifndef, ifeq, ifneq) during makefile parsing, line-by-line in the order they appear [1][2][3]. For ifdef/ifndef, the process is: 1) Expand the variable-name argument to determine the target variable name (e.g., $(foo) expands to "bar" if foo=bar) [1][4][5]. 2) Check if that target variable has a non-empty value (for ifdef) or empty value (for ifndef), without expanding the target variable's value [1][5]. Variables never defined are empty [1]. For ifeq/ifneq, expand both arguments fully and compare the results [1][2]. Conditionals can nest, with each inner conditional evaluated independently based on the current variable state at parse time; the first matching branch (or else) takes effect, skipping subsequent branches until endif [1]. Variable assignments inside conditionals only take effect if their containing conditional block is read (true) [1][6]. All expansions use the current variable values at the moment the conditional line is parsed [7][3]. Automatic variables cannot be used as they are undefined until recipe execution [2][8]. Example from docs: bar = true; foo = bar; ifdef $(foo) sets frobozz=yes because $(foo) expands to bar, and bar has non-empty value [1]. If bar =, then ifdef foo would be false since foo expands to empty [1].

check-bats target currently blocks all make targets during parsing when bats is missing.

The ifndef BATS conditional is evaluated at parse time (during makefile reading), so make init, make help, and any other target fail before target selection occurs. Move the check into the recipe body so only check-bats (and its dependent health target) require bats.

Proposed fix
-BATS := $(shell command -v bats 2> /dev/null)
-
 .PHONY: check-bats
 check-bats: ## Check if bats is installed
-ifndef BATS
-	$(error "bats-core not found. Please install it (e.g., 'sudo apt install bats' or 'npm install -g bats')")
-endif
+	`@command` -v bats >/dev/null 2>&1 || { \
+		echo "bats-core not found. Please install it (e.g., 'sudo apt install bats' or 'npm install -g bats')"; \
+		exit 1; \
+	}

In `@Makefile` around lines 6 - 8, The top-level ifndef BATS causes make to error
during parse; instead remove the parse-time ifndef and put the existence check
inside the check-bats target recipe so only running check-bats (and its
dependent health target) fails when BATS is missing. Concretely, delete the
current ifndef/endif block and update the check-bats target to test BATS at
recipe runtime (e.g., a shell test that prints the same install guidance and
exits nonzero when BATS is unset), ensuring the health target still depends on
check-bats.
