wdsync 0.2.0

Mirror dirty files from a Windows Git repo into a matching WSL repo.

wdsync

wdsync is a WSL-side Python CLI for mirroring the dirty working tree of a Windows Git repository into a matching WSL repository without requiring a commit, push, or pull cycle.

It is built for the workflow where:

• your primary editing happens to be on Windows for whatever reason (Flutter, VS Studio, .NET development, etc.)
• your backend, scripts, containers, or Linux tooling run in WSL either for prod or testing parity
• you want the WSL repo to mirror the current Windows dirty-set (staged and unstaged changes) on demand

The key design choice is that wdsync reads the source repo with git.exe, so the sync set matches what Git for Windows considers dirty rather than what Linux Git thinks about /mnt/c/....

What It Does

From inside a destination WSL repo, wdsync will:

• read a local .wdsync file
• resolve the Windows source repo from SRC=/mnt/c/...
• query the source dirty set using git.exe (Windows Git)
• preview by default to see the planned dirty set in the destination WSL repo
• sync when you run wdsync sync or wdsync -f
• warn with wdsync doctor when source and destination HEAD differ or the destination repo is already dirty

Note: It includes tracked unstaged files, tracked staged files, and untracked files, including nested files in untracked directories. Deleted files detected in the source are propagated to the destination (removed from the WSL repo). If a deletion fails due to permissions, wdsync prompts to retry with sudo. Files with local changes in the destination are never deleted. It does not yet do patch-apply checks, staging/index mirroring, or global config.

Prerequisites

Get git available in WSL and Windows (git.exe), plus rsync, wslpath, Python 3.11+, and either uv or pip; the source repo must be reachable as /mnt/<drive>/....

Install

• Read the detailed Setup guide here | Recommended install path:

uv tool install wdsync

Alternative install path with pip after python venv:

python -m pip install wdsync

Per-Project Config

Each destination WSL repo gets a local .wdsync file at the repo root:

SRC=/mnt/c/Users/YourName/path/to/WindowsRepo

Example:

SRC=/mnt/c/Users/<User>/Documents/Projects/<ProjectName>

wdsync init writes this file for you and adds .wdsync to the destination repo's .git/info/exclude so it stays local.

Quick Start

From inside the destination WSL repo:

wdsync init /mnt/c/Users/YourName/path/to/WindowsRepo
wdsync
wdsync sync

Doctor mode: Explain potential sync risks from source and destination state:

wdsync doctor

Commands

Command	JSON Output	Purpose
wdsync	Yes, with wdsync --json	Preview the current source dirty set.
wdsync preview	Yes, with wdsync preview --json	Explicit preview mode.
wdsync sync	Yes, with wdsync sync --json	Copy the planned dirty files into the current WSL repo.
wdsync init <SRC>	No	Create .wdsync for the current destination repo.
wdsync doctor	Yes, with wdsync doctor --json	Show advisory sync-risk checks for source and destination state.
wdsync shell install	No	Install optional shell helpers and completions.

Git Status Labels Passed

| [unstaged] [ M] | [staged] [M ] | [both] [MM] | [new] [??] | [added] [A ] | [added+mod] [AM] | [renamed] [R ] | [copied] [C ] | [deleted] [ D] | fallback [changed] |

Shell Integration

The CLI itself is shell-agnostic once installed. Optional shell helpers can be installed with:

wdsync shell install

Override shell detection when needed:

wdsync shell install --shell fish
wdsync shell install --shell bash
wdsync shell install --shell zsh

What shell install does:

• auto-detects fish, bash, or zsh
• installs completion assets
• installs a wdsync-init helper wrapper
• installs fish function delegates when using fish

The scripts/ directory contains thin repo-local wrapper examples that delegate to the installed CLI or fall back to uv run.

• scripts/bash/ contains executable shell wrappers
• scripts/fish/ contains fish functions
• the bash wrappers also work fine as standalone executable helpers from zsh

Important Behavior Notes

Source dirty-file detection comes from git.exe, not Linux Git. Preview shows the full source dirty set rather than a destination diff, and sync copies file contents only. A source staged file does not remain staged in the destination repo. Deleted files are propagated to the destination: if a file was deleted in the Windows source, wdsync sync removes it from the WSL repo. Files that have local changes in the destination are skipped to avoid destroying local work. If a deletion fails due to file permissions, wdsync will prompt to retry with sudo. Renames and copies are parsed correctly from porcelain v1 -z and untracked directories are expanded to leaf file paths.

Limitations

wdsync is WSL-only, supports one source path per destination repo, and expects the source path to live under /mnt/<drive>/.... It does not yet run patch-apply checks or support post-sync hooks.
