Fixes #14428

mise bootstrap asked files: apply ~? for a copy-mode dotfile group, which says nothing about which files would change or that local edits may be overwritten.

Before the confirmation, apply now lists what it will do and warns about it:

  overwrite ~/.bashrc
  create ~/.config/foo/config.toml
files: applying makes the live targets match the repository, replacing local edits.
files: run `mise dot diff` to review the differences first.
files: apply ~? [y/N]

• Directory copies list each file as create or overwrite; files already identical to the repository version are left out. A symlink at the target shows as replace symlink, a directory where a file belongs as conflict (not a file):, and a file at the target root as replace <target> with a directory.
• Empty remove_empty templates show as rm <target>; other modes show their usual one-line description.
• The prompt now defaults to No. --yes and non-interactive runs are unchanged.

Validated with unit tests for the preview lines and clippy; no e2e run. The trusted / lint failure is cargo deny reporting a new RustSec advisory, unrelated to this change.

Note

Low Risk
Changes only the interactive apply confirmation UX and preview text; apply execution logic is unchanged aside from the safer default prompt.

Overview
Interactive files: apply now prints a per-action preview before asking for confirmation, instead of only showing a comma-separated target list.

Directory copy requests are expanded into individual lines (create, overwrite, replace symlink, replace … with a directory, rm, and conflict … for blocking paths, dangling symlinks, etc.). Files that already match the source content (and Unix permissions) are omitted from the list. Stale reconciliation links are shown as rm lines.

A short warning explains that apply overwrites local edits and suggests mise dot diff. The confirmation prompt defaults to No via confirm_with_default; --yes and non-interactive behavior are unchanged.

Unit tests cover directory-copy previews, edge cases, and empty template removals.

Summary by CodeRabbit

• New Features
  • Apply confirmations now break directory copies into individual file actions and report whether the destination root will be created or replaced.
  • Confirmations show file creations, overwrites, symlink replacements, and empty-template removals as rm. They also report conflicts caused by dangling symlinks or paths that block parent directories.
  • Files with matching content and Unix permissions are omitted from the action list. The confirmation prompt defaults to “no.”

📝 Walkthrough

Apply confirmation now lists planned actions for files in directory copies and empty-template removals. It omits matching files and defaults to No.

Changes: Dotfile apply confirmation

Layer / File(s)	Summary
Interactive apply confirmation src/system/files.rs	Directory-copy confirmations list planned actions, including file creation, overwrite, symlink replacement, and conflicts. Matching files are omitted when contents and, on Unix, permissions match. Empty-template removals appear as rm. Tests cover these confirmation outputs.

Merge Risk: 🔵 Low · up to c950c

A narrow hard-link case can make apply empty a source file that the new preview omits. This is a bounded data-loss risk; owner awareness or a targeted follow-up is warranted.

Explanation

The implementation satisfies most coding requirements in [#14428]. confirmation_lines lists planned paths and actions, omits matching files, reports conflicts and removals, and the prompt warns about replacing local edits and defaults to No. The warning says to run mise dot diff. [#14428] specifically requests recommending cancellation and running mise -C ~ dot diff. The reviewed code does not establish that the shorter command selects the required configuration.
