Changelog

Changed

• Pushing main now runs the checks and deploys automatically through a pre-push hook.

Added

• A changelog page lists every release, newest first. The version in the top bar links to it.

Added

• Ctrl/Cmd+S saves a file opened from disk right away, instead of opening the browser's Save Page dialog. It works from inside the editor too.

Fixed

• Changing a label setting to the value it already has no longer saves the file again.

Added

• Open .zpl files from disk. Edits are written back to the file, and changes made to it in other programs show up in the editor.
• Disk files show a floppy icon in their tab, panel header and library row. If the browser loses access, the panel header offers Reconnect, or Find file when the file has moved.
• Removing a disk file from the library leaves the file on disk untouched.

Changed

• The panel's last toolbar button closes its tab instead of duplicating the file. The file stays saved, and focus moves to the next tab.

Added

• Links can carry plain base64 ZPL in a base64 parameter, so other tools can link straight to a label. Optional dpmm, w and h set the label settings.

Changed

• All the labels in a file render from one Labelary request instead of one per label, so long jobs render faster and stay under the rate limit.

Added

• Renders are cached in the browser, so reloading the page doesn't ask Labelary for labels it already drew. The 500 most recent are kept.

Fixed

• Tab close buttons are easier to see and react on hover.

Fixed

• File name fields no longer show the browser's autocomplete suggestions.

Fixed

• Copy and download buttons are disabled while the editor is empty.

Changed

• The empty preview has a clearer title and hint, in muted inset text, with a credit to Labelary.

Changed

• The "Explain code" toggle is gone from the top bar. Hovering a command still explains it.

Fixed

• The Files button no longer shows a tooltip over its own menu.

Fixed

• Buttons whose label already says what they do, such as zoom and tab close, no longer show a tooltip repeating it.

Added

• Files are saved in a library in your browser. Open, rename and delete them from Files, and switch between open files with tabs in the top bar.
• Up to four files can be open at once. Closing a tab keeps the file saved.

Changed

• The project and its Worker are named zpl.

Fixed

• Two-finger scrolling on a trackpad scrolls the preview instead of zooming it. Pinch or Ctrl/Cmd+scroll to zoom.

Added

• With Sync zoom on, scrolling one preview scrolls the others too.

Added

• Zoom a preview by pinching or scrolling over it, keeping the point under the pointer in place.
• A "Sync zoom" toggle in the top bar zooms every preview together once two panels are open.

Changed

• App-wide controls (Explain, Compare, Add panel) live once in a new top bar, and each panel header fits in a single row.
• Narrow panels hide their least used buttons instead of wrapping.

Changed

• Every panel action is a visible button in the header: label size, Explain and Compare, copy ZPL, base64 or share link, PDF, PNG or ZPL downloads, duplicate and close.
• Zoom out, zoom in and Fit are buttons in the status bar.

Changed

• The Explain toggle moved into an options menu at the end of the status bar.

Changed

• With several panels open, each shows its label on top and the code below it.

Changed

• Every preview, export and comparison is rendered by Labelary. Labelary's linter warnings are underlined in the editor.
• The Live/API switch, the Labelary comparison and click-to-code are gone.

Changed

• The sample on first visit is the classic Intershipping shipping label.

Added

• A logo, favicon and app icons, and a preview image when the editor's link is shared.

Added

• Hovering a command explains what it does and what each value means, in dots and inches.
• An Explain toggle adds a plain-language summary at the end of each line.

Added

• A warning in the status bar when the ZPL's ^PW or ^LL asks for another label size, with a button to switch to it.

Fixed

• The label size settings override ^PW and ^LL, like loading different media in a printer.

Changed

• The status bar holds the preview's controls: the label size opens the settings, and Compare, Zoom and panel actions are menus.

Changed

• Tooltips wait a moment before opening, so they don't flash while moving the pointer.
• The Live and API preview options have icons.

Fixed

• The selected option in a toggle stands out from the one under the pointer.

Changed

• A Live preview / API preview switch in the preview header picks the renderer.

Changed

• Actions no longer announce themselves in toast notifications.

Changed

• The top header is gone: Add panel and the Labelary toggle moved into the panels.
• The page no longer rubber-bands when scrolled past its edge.

Changed

• The app loads less code up front. The renderer and PDF export load when first needed.

Fixed

• Lint and formatting errors in generated components and configs.

Added

• Compare a panel's label with another panel's, side by side or as a difference view.

Added

• Copy a share link that carries the label and its settings. The ZPL stays in the link's fragment, which is never sent to the server.

Changed

• The README describes the ZPL editor.

Changed

• Template leftovers and the unused German locale are removed.

Added

• Downloads ask for a file name first, and ZPL can be downloaded as a file.

Added

• A "Labelary preview" switch draws every preview with Labelary instead of the built-in renderer.

Fixed

• The preview fits the whole label on load, not just its width.

Added

• Compare the preview with Labelary's render, side by side or as an overlay that marks the dots that differ.

Added

• The editor is also served at zpl.puuid.com.

Added

• Several ZPL panels side by side, each with its own label, settings and zoom.

Added

• The editor is served at zpl.odeschenes.dev.

Added

• A ZPL editor with a live label preview. Click a field in the label to jump to its code.
• Pasted or dropped base64 is decoded to ZPL.
• Problems are underlined in the editor, and labels export to PNG or PDF or copy as ZPL or base64.

Added

• Helpers to decode base64 ZPL, render labels and export them.

Changed

• A monochrome theme that follows your system's light or dark mode, with Geist fonts.

Added

• The project, created from the TanStack Start template.
