mise activate bash --no-hook-env applies the config's environment anyway. The other three shells do not.

Measured, one tool configured and installed, checking whether it lands on PATH at activation:

shell	--no-hook-env	no flag (control)
bash	applied	applied
zsh	not applied	applied
fish	not applied	applied
pwsh	not applied	applied

And with an [env] entry rather than a tool, which is the plainer statement of it:

$ printf '[env]\nNO_HOOK_ENV_PROBE = "applied"\n' > mise.toml
$ bash --noprofile --norc -c 'eval "$(mise activate bash --no-hook-env)"; echo "${NO_HOOK_ENV_PROBE:-unset}"'
applied          # zsh, same config: unset

Not a design choice — the call moved

bash used to match the others. Before src/assets/bash/activate.sh existed, bash.rs emitted the activation-time call inside the flag's guard:

if !opts.no_hook_env {
    out.push_str(&formatdoc! {r#"
    …PROMPT_COMMAND…
    chpwd_functions+=(_mise_hook)
    _mise_hook            // inside
    "#, …});
}

48e5dd59ca7d — "fix(bash): avoid duplicate trust warning after cd" (#8920) — extracted that script into the asset file, and the call came out from under the guard on the way. The subject of that change was duplicate trust warnings; --no-hook-env is not mentioned in it.

Nothing pins the current behaviour either: the test that same commit added, e2e/env/test_bash_first_prompt_after_activate, activates with --status, not with the flag, and no bash test covers --no-hook-env at all. e2e/cli/test_activate_export does use it, but only to check __MISE_EXE, which is exported at the top of the script outside any guard — unaffected by this change.

The flag's own summary line is "Do not automatically call hook-env". Applying the environment at activation is calling hook-env.

The change

The call joins the guard that immediately follows it — the one already setting __MISE_BASH_SKIP_FIRST_PROMPT, which exists because _mise_hook just ran, so the two belong under one condition:

if [ "$__MISE_HOOK_ENABLED" = "1" ]; then
	_mise_hook
	__MISE_BASH_SKIP_FIRST_PROMPT=1
fi

Test

e2e/env/test_bash_no_hook_env asserts an [env] entry is not applied with the flag, and — the control — that it is without it, so the first check cannot pass against a mise that never applies the environment at all. Verified against the current release: it fails there with --no-hook-env applied the environment at activation: NO_HOOK_ENV_PROBE=applied, which is the bug.

Draft

Opened as a draft: this changes what an existing flag does for bash users. The history says the current behaviour is accidental, but somebody may have come to rely on activating with --no-hook-env and still getting their tools — worth your call before it lands.

No local build was run — this machine cannot build mise, so type checking and the snapshot are CI's. The measurements above are all from released binaries.

Summary by CodeRabbit

• Bug Fixes

  • Fixed Bash activation so the initial environment hook is skipped when hook processing is disabled.
  • Ensured the --no-hook-env option leaves configured environment variables unset while normal activation continues to apply them.

• Tests

  • Added end-to-end coverage for Bash activation with and without --no-hook-env.

📝 Walkthrough

Walkthrough

Bash activation now guards the initial hook with __MISE_HOOK_ENABLED. A new end-to-end test verifies that --no-hook-env leaves the configured environment unset and that normal activation applies it.

Changes

Bash no-hook-env behavior

Layer / File(s)	Summary
Guard activation and verify environment behavior src/assets/bash/activate.sh, e2e/env/test_bash_no_hook_env	The initial _mise_hook call runs only when __MISE_HOOK_ENABLED equals 1. The Bash test validates activation with and without --no-hook-env, including activation errors and inherited environment cleanup.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to e7c05

The change makes Bash honor --no-hook-env consistently by preventing environment application during activation, with a regression test covering both flagged and default behavior. No actionable merge-blocking risk remains after normal checks.

Poem

I’m a rabbit checking Bash today,
The hook now waits when flags say stay.
With no-hook-env, the value stays clear;
With normal activation, it appears.
Hop, hop—both paths are tested here!

Greptile Summary

The PR restores Bash’s --no-hook-env behavior by guarding the initial environment hook consistently with the other supported shells.

• Moves the initial _mise_hook call under __MISE_HOOK_ENABLED.
• Sets the first-prompt skip marker before running the guarded initial hook.
• Adds end-to-end coverage for activation both with and without --no-hook-env.
• Updates the Bash activation snapshot.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains.

Important Files Changed

Filename	Overview
e2e/env/test_bash_no_hook_env	Adds regression and control cases; the revised probe now propagates activation and eval failures through explicit exits and the inherited pipefail setting.
src/assets/bash/activate.sh	Correctly places the initial Bash environment hook and its first-prompt skip marker under the hook-enabled guard.
src/shell/snapshots/mise__shell__bash__tests__activate.snap	Accurately reflects the updated rendered Bash activation script.

invoking probe for the --no-hook-env assertion, so the check starts from an
unset environment and only observes activation behavior. Keep the existing probe
function and assertion unchanged.
- Around line 12-14: Update the probe function so it captures the output and
exit status of mise activate bash $1, then checks both the activation and eval
statuses before printing NO_HOOK_ENV_PROBE; propagate a non-zero activation
failure instead of treating an empty generated script as successful.
