feat: XDG directory layout via VpDirs by forehalo · Pull Request #2346 · voidzero-dev/vite-plus

forehalo · 2026-08-05T13:06:23Z

Close #827

Summary

Centralize on-disk paths in vp_shared::VpDirs and default fresh installs to the split XDG/platform layout. Existing default installs under ~/.vite-plus remain on the legacy monolithic root for now (grandfathered via existence-gated resolution). Automatic layout migration is out of scope here and tracked as follow-up work.

Resolution (high level)

Ordered sources (per category): deprecated VP_HOME (custom full-root pin) → existing ~/.vite-plus / ./.vite-plus (exist-gated legacy mapping) → VP_BIN_DIR / VP_DATA_DIR / VP_CACHE_DIR → XDG_* → platform defaults.

Category	Split default (Unix)	Legacy (`~/.vite-plus`)
bin	`~/.local/bin`	`<root>/bin`
data	`~/.local/share/vite-plus`	`<root>`
cache	`~/.cache/vite-plus`	`<root>/cache`
config	`~/.config/vite-plus`	`<root>`
state	`~/.local/state/vite-plus`	`<root>`

Windows split uses %LOCALAPPDATA%\vite-plus\{bin,data,cache,state} and %APPDATA%\vite-plus for config. Relative VP_* / XDG_* values are treated as unset.

Commits (review order)

docs(rfc): document split directory layout via VpDirs
- Adds rfcs/directory-layout.md describing the resolution chain, grandfathering, installer alignment, and follow-ups (VP_HOME cleanup, migrate-on-upgrade).
- Historical RFCs (e.g. env-command.md) are left unchanged.
feat(shared): introduce VpDirs with strategy-gated path resolution
- Replaces get_vp_home / home.rs with VpDirs + dirs/resolution.rs strategy chain.
- Category roots and first-level data subdirs only; deeper paths stay with owning features.
- Wires EnvConfig / env vars so tests isolate layout via test_guard / for_test_with_home without process-env leaks.
- Updates AGENTS.md pointer to the central path API.
refactor: migrate call sites from get_vp_home to VpDirs
- Migrates global CLI, shims, js_runtime, package manager, implode, env setup/doctor, and related helpers onto VpDirs.
- Under the split layout, injects VP_BIN_DIR / VP_DATA_DIR / VP_CACHE_DIR into JS children when unset; hooks / org-tarball honor those roots.
- Snapshot runner and fixtures provision a full legacy on-disk shape and pin install roots explicitly (no binary PATH self-location in VpDirs).
- CI bootstrap seeds ~/.vite-plus before bootstrap-cli so existing snapshot/e2e paths keep finding the global binary until layout cleanup lands.
feat(install): default installers to the split XDG layout
- install.sh / install.ps1 / vp-setup / trampoline / Dockerfile / install-global-cli share the same resolution chain as the CLI.
- Fresh install → split; existing ~/.vite-plus or explicit VP_HOME / --install-dir → legacy monolithic root.
- Installer env docs (VP_HOME deprecated) and standalone-install CI coverage for split + legacy upgrade/implode.

User impact

Install	Impact
Existing `~/.vite-plus`	Unchanged path (grandfathered until migrate follow-up)
Custom `VP_HOME`	Still works (deprecated pin)
Fresh	Split layout; typically only `~/.local/bin` needs to be on PATH

Follow-up

chore: remove remaining VP_HOME usage (especially snapshot tests) #2371 — Clean remaining VP_HOME usage in the repo (especially PTY snapshot tests); prefer VP_*_DIR / XDG
feat: migrate ~/.vite-plus into split VP_*/XDG dirs on vp upgrade #2372 — On vp upgrade, migrate default ~/.vite-plus contents into split VP_*_DIR / XDG_* / platform dirs and remove the legacy root

Test plan

cargo check / unit tests for dirs resolution and layout helpers
Snapshot fixtures adapted for layout isolation (pin VP_HOME / disable shared seed where fakes are used)
Installer unification (single install.sh / install.ps1)
Formatting for RFC + install-global-cli
Windows unit test: uninstall removes shims under for_test_with_home bin mapping
CI: test-standalone-install (released + local split/legacy-upgrade jobs)
Manual: fresh install lands on split paths; existing ~/.vite-plus still works without moving

@liangmiQwQ Your refactor needs to wait until this merge is completed first, as the changes are expected to be quite significant.

IMO, I would be a little bit curious about the benefit for this move. The current VP_HOME layout has been working well, the similar single-root approaches are also used by tools like Cargo, Bun, and Volta. Moving to a new layout is not a low-cost change: it affects existing installations, upgrade paths, user workflows, and debugging. For a released tool, I think we should carefully evaluate the trade-offs.

For example, I help maintain the Vite+'s global package installations in several, I'm concerned that using ~/.local/bin may introduce heavier binary conflicts and overlapping issues. I'm not sure if ~/.local/bin, a public bin location, should be managed (even partially) by Vite+.

I'm not against this direction, I just want to understand the motivation and the problem it solves. If it does help Vite+ improve, then now is really a good time to implement it (before RC).

@liangmiQwQ Following the XDG directory convention will allow Vite+ to be more widely accepted, and many mature developer tools follow this convention, such as Claude Code and uv astral-sh/uv#8420

Capture the resolution design, grandfathering of existing ~/.vite-plus installs, installer alignment, and follow-ups for VP_HOME cleanup and migrate-on-upgrade.

Replace get_vp_home / the monolithic home module with VpDirs: category roots (bin, data, cache, config, state) come from an ordered resolution chain in dirs/resolution.rs (legacy Exist-gated grandfathering, VP_* and XDG Set overrides, then platform defaults), and first-level data subdirs (current, js_runtime, package_manager, packages, bins) are pure joins. Files and deeper trees stay with their features. Wire EnvConfig so test_guard/for_test_with_home isolate install roots without process-env leaks. Groundwork for voidzero-dev#827.

Switch global CLI, shims, js_runtime, package_manager, and related helpers off the old home path helpers onto VpDirs. Inject VP_BIN_DIR/VP_DATA_DIR/ VP_CACHE_DIR into JS children under the split layout; teach hooks and org-tarball to honor those roots. implode, env setup/doctor, and snapshot fixtures understand split vs legacy layouts without binary self-location (pin VP_HOME / isolated roots explicitly in tests).

Fresh installs land versions under the data dir and shims under the bin dir (XDG/platform defaults via VpDirs). install.sh, install.ps1, vp-setup, Dockerfile, trampoline, and install-global-cli follow the same resolution chain as the CLI; an existing ~/.vite-plus or explicit VP_HOME/--install-dir keeps the legacy monolithic root. Document the installer env surface (VP_HOME deprecated) and cover split plus legacy upgrade/implode paths in standalone install CI.
