Show HN: GWZ – Git Workspace Zone (multi-repo that feels like plain Git)

Coming from the land of the mono-repo (ex-googler), I decided to embrace the multi-repo, plain-git style. Methought, “hey, submodules, what could possibly go wrong”. Well, how about everything: detached HEADs, impossibly tedious commit management, and just about everything else. "OKAY" I said, a simple Python script should be fine, right? Well, NO. It turns out to be more complex. So I thought "others have got this, right? My time in mono-repo land was long and someone will have solved this" — well, yeah NAH. I won't bore you (the longer, boring comparison is in the docs) but everything I tried had baggage. All I want is a tool that gets out of my way and makes my multi-repo look like a mono-repo when I want, and a multi-repo when I want. I want my cake and I want it now.

"claude, codex and gemini, make me gwz" I said, "and make it work much like using git itself" I said — which they proceeded to ignore, but after many rounds in the rink, they produced a product which is delightfully good at the goal. I have to admit, the little beasties did take some creative license and made it better than I asked.

So what does gwz do?

- Member repositories remain ordinary Git repositories. No submodules unexpectedly detaching (unless you ask to materialize to a tag/snapshot). - “Snapshots” and “commit markers” can recover workspace state. That state lives in the root repo. - The similarities don't end at gwz being 3 letters starting with "g", no, gwz has status, diff, add, pull, push, commit, tag, stash, clone, init all play similar (not exact) roles to their git namesakes. - Extra commands to manage members: gwz repo create / clone / add / sync / detach / attach. - A “forall” command that runs anything across selected member repos.

Also, the member repos are hidden from the root repo's git (via .git/info/exclude), so you can't mess up the members from the root.

For my daily workflow gwz is great, and it's now my goto — I hardly use raw git anymore. But gwz, like any form of art, will never be finished. There's always more, but; it's now time to lift the veil, shine the light or yell from the rafters.

Caveats: it's written in Rust and I can't yet write Rust if my life depended on it. So why Rust and not Python or C++ (my usual gotos)? I have another project that needs to manage repos, which meant gwz had to be carved up into a CLI and a "core" crate with a typed protocol between them — so the engine is embeddable and wire-friendly, not fused to a terminal. That other project's target is also Rust, and (suspense) it's not ready to reveal, so: stay tuned.

The little LLM helpers created copious amounts of very fine documentation (seriously), which I invite you to peruse at: https://owebeeone.github.io/gwz-cli/

One interesting LLM initiated feature (I did not ask for it but it sounded good and it falls out as part of the gwz-core protocol anyway) is the “--json/jsonl” output which seems to give LLMs much better context of the response. Who woulda thunk, an LLM making its own lingo.

Honest state:

- It has a few rough UX edges, nothing so egregious it'll make you chunder. - Across gwz-core, gwz-cli and gwz-py, gwz currently has 764 tests, with roughly 82% line coverage. - For my workflow gwz is great. YMMV (tell me about it - good, bad or indifferent, Nah, scratch that, only the good). - gwz-dev - the root gwz repo is a “gwz managed” repo. Eat your own fishfood. - The CLI comes in Rust and Python variants. I use the Rust gwz daily; the Python gwz-py should work but gets less use, so it probably has bugs — it started life as a validation harness proving the core's message protocol holds up when driven from a second language. - It's v0.9.2 and pre-1.0: the protocol and some command surfaces may still move. - GPL-2.0-only, the same license family as git.

    Windows

    Each story opens in a window holding its article above its discussion; drag the bar between them to share the room differently. A window can be moved by its title bar, resized from any edge, snapped to a half or a corner by dragging it there, maximised, or minimised to the bar at the foot of the page. Use Window > New reader window to open an empty reader, or Story > Open in new reader window to open another reader for the current article. Docked readers keep their articles when you select another story from the sidebar. Minimized readers can be restored and reused for their site. A window's Next story link reads on down the list in the same window.

    A link in a comment or an article to another Hacker News or Lobsters thread opens that thread in a window too. A link to a single HN comment opens the comment above its replies.

    While a story's window is in front, the Story and Discussion menus in the menu bar hold its commands: pinning, Next story, sorting, collapsing every thread, jumping to the first new comment. Each window also remembers where you were in its article and discussion, so a reload, or Back to a story that Next took you past, finds your place again. Closing a window forgets it.

    The whole arrangement lives in the address, so a bookmark or a shared link brings it back, and Back undoes the last change. Moving between Hacker News, Lobsters, their lists, Pinned and Find changes only the list, and leaves the windows open.

    The list

    The pin at the start of a row keeps the story in Pinned, and the cross at its end hides it. Pinned can be narrowed by words in the title, site or author, by source, and to the stories you haven't opened yet, and ordered by when you pinned them, by points or by comments; the filters are part of the address, so a filtered view can be bookmarked. Scroll past the end of the list to load more. Domain filters, in the View menu, hide every story from a site.

    Collections are named lists of stories. Story > Add to collection files the story in front into one or more of them, and the Collections feed shows them all or one at a time; the menu that chooses collections also creates, renames, and deletes them. A note is your own text on a story. Choose Add note in a story's toolbar to write one; it saves as you type. Rows with a note carry the note mark, and the Notes feed lists every noted story and searches the text of your notes.

    Browsing view

    View > Windowed and View > Classic select the browsing view and save your default in this browser. Window view reuses a reader for each feed. Classic view opens stories and applets as pages. Open as a page is a one-off action that does not change your saved default. Use the Windowed selector to return an article to a window. Direct page links always open as pages.

    Applets

    The Applets menu in the menu bar holds three tools, each a window of its own. Replies to me takes your Hacker News user name and lists the replies to your last thirty comments and stories, checking again every three minutes while it is open, and marking what is new since you last marked them read. Look up a user opens a profile on Hacker News or Lobsters, with their submissions and recent comments, as a commenter's name in any discussion does; the bar at the top of a profile looks up someone else in the same window, and Back returns to the one before. Who is hiring? filters the posts of HN's monthly hiring threads by the words you type.

    They read only what the sites publish to everyone, so none of them asks for a login, and your user name stays in this browser anonymously and is included in retained applet state when signed in.

    Find

    Find takes any link and lists every time it was submitted to Hacker News and Lobsters, so you can read each discussion of it.

    About

    YAVCHN never sees your Hacker News or Lobsters login. The discussion is fetched from each site's public API; to vote or reply, follow the link above the discussion, or the arrow beside a comment, to the source's own site. Without a YAVCHN account, your data stays in this browser. When signed in, pins, collections, notes, blocked domains, and retained reading state are stored with your account and synchronized across devices. Hidden stories and layout stay in this browser. The privacy policy has the details.
