v0.1.6

Highlights

Two Windows-facing fixes found during testing on a Windows VM after v0.1.5.

Fixed

• Inline cell editor no longer hides text behind scrollbars on Windows. The editor was a fixed cell-height <textarea> with overflow: auto; Windows classic scrollbars (~17px each) left only ~11px of the 28px cell for text, so you couldn't see what you were editing. The editor now grows to fit its content — long values wrap (no horizontal scrollbar) and the height tracks the content (no vertical scrollbar until a 50vh cap), floating over neighbouring cells as an overlay. macOS overlay scrollbars had hidden this, so it shipped unnoticed. Reported by @SweetSophia (#2).
• Windows application icon is now the custom CSV icon instead of the Wails default "W" logo. build/windows/icon.ico still held the wails init template default — macOS regenerates its .icns from build/appicon.png every build, but the Windows .ico is a static file that was never updated when the custom icon was adopted. Regenerated with the full size set (16–256, PNG-compressed).

v0.1.5

Highlights

Small UI polish release. No data-handling or editing behavior change.

Fixed

• macOS "About CSV Editor" panel now shows the actual build version. Previously the panel always read "1.0.0" because Wails templates CFBundleShortVersionString to that default and csv-editor never overrode it. The panel now sources its version, title, message, and icon from Mac.About in wails.Run, populated from the same version ldflag the binary itself reports — application menu, About panel, and any programmatic version readout stay in agreement from one input.

Added

• macOS Window menu (Minimize / Zoom / Bring All to Front) is now part of the standard macOS menu chain. Their absence was easier to notice once the About panel started working.

v0.1.4

Highlights

Three runtime safety improvements + Linux scope clarification. No user-visible feature change.

Security

• Saved CSV files are created with 0600 permissions (owner read/write only), down from 0644. CSV files often contain PII; the previous mode left files world-readable on disk even with the default macOS umask, which could expose rows when saving into shared, cloud-synced, or backed-up directories. Existing files keep their current permissions on overwrite.

Fixed

• File ▸ New Window no longer leaks zombie child processes. RequestNewWindow now reaps the spawned process via cmd.Wait in a goroutine and returns early on cmd.Start failure, preventing a defunct entry per new-window invocation from accumulating in the parent process table on Windows. On macOS the wait completes essentially immediately because the spawn goes through open(1).

Changed

• File loads are now bounded to 500 MB. Open / drag-drop / Open Recent refuse files larger than that with file too large: <path> exceeds 524288000 byte limit instead of attempting to read the whole file into memory. csv-editor's stated target is hundreds of thousands of rows (~100 MB worst case for typical column counts), so the cap sits well above legitimate use while protecting the app from OOM on an accidental multi-gigabyte open. Implemented via io.LimitReader so a file that grows between Stat and Read still cannot blow the read buffer.

Documentation

• README (en/ja) and CLAUDE.md now declare Linux explicitly out of scope. Drive-by Linux porting PRs will be declined; users on Linux should use LibreOffice Calc or Modern CSV. See the closed PR #1 thread for the rationale.

Acknowledgments

The three runtime changes above were originally surfaced by @SweetSophia in PR #1 (closed without merge). The code was rewritten from scratch with freshened helper signatures, tests, and rationale before landing.

v0.1.3

Highlights

macOS builds are now Developer ID signed and Apple-notarized.

Replaces Wails's default ad-hoc signature with a full Apple Developer ID Application signature on the .app bundle (Hardened Runtime + Apple secure timestamp + minimal WebKit JIT entitlements). make package submits the bundle to Apple's notary service and staples the ticket onto the .app so offline first-launch works without a Gatekeeper verification dialog.

End users on macOS no longer need the right-click → Open workaround documented in v0.1.2's README. Local users who place csv-editor.app under Dropbox / iCloud / OneDrive-synced paths are no longer killed by macOS's ad-hoc + provenance distrust policy (recent macOS releases SIGKILL ad-hoc-signed binaries that carry FileProvider-stamped com.apple.provenance xattrs).

Windows .exe remains unsigned. Authenticode signing is not yet in place — SmartScreen still shows "Windows protected your PC" on first launch.

No behavior change to the editor itself — feature-wise this is identical to v0.1.2.

v0.1.2 — multi-line cells, multi-window, Cmd+W

Adds in-cell newline editing, multiple windows (via separate processes with a cascade offset), Cmd+W close, and fixes column widths leaking into File ▸ New.

What's new

Added

• Multi-line cells: quoted multi-line CSV fields are now both visible and editable. Single-line cell view shows newlines as a muted ↵ glyph; the inline editor is a <textarea> with Alt+Enter to insert a literal newline. Enter still commits.
• File ▸ New Window (⇧⌘N on macOS, Ctrl+Shift+N elsewhere) opens a fresh csv-editor instance — Wails v2 is single-window per process, so multi-file means multi-process. The new window opens at the parent's position + (30, 30) cascade offset, and child instances skip the OnBeforeClose state save to keep your primary frame intact.
• File ▸ Close Window (⌘W / Ctrl+W) wired to the standard shortcut. Since one window per process, this also exits the app, with OnBeforeClose firing first so window state persists.

Fixed

• File ▸ New no longer inherits the previous file's per-column widths.

See CHANGELOG.md for details.

v0.1.1 — window state persistence

Bug-fix and quality-of-life release.

What's new

Added

• Window position and size are now persisted to the config file (window.x, window.y, window.width, window.height) and restored on next launch.

Changed

• Removed a Wails template's // replace ... => /Users/magi/... comment from app/go.mod (local-path leak, no functional impact).

See CHANGELOG.md for details.

v0.1.0 — initial release

Initial release of csv-editor — a CSV/TSV viewer & editor GUI for macOS (Apple Silicon) and Windows 11.

Built with Wails v2 (Go + React/TypeScript). Designed to replace TableTool with a maintained, ARM64-native alternative that handles Japanese encodings (UTF-8 / Shift_JIS / CP932), row/column copy operations, and TSV clipboard expansion correctly.

See CHANGELOG.md for the full feature list.

Installation

Binaries below are unsigned to avoid signing-certificate cost. Workarounds:

• macOS Gatekeeper: right-click `csv-editor.app` → Open → confirm.
• Windows SmartScreen: click "More info" → "Run anyway".

Supported platforms

• macOS 12+ on Apple Silicon (`darwin-arm64`)
• macOS 12+ on Intel (`darwin-amd64`, best-effort)
• Windows 11 (`windows-amd64`)

Linux is out of scope — see RFP §7.

Binary assets will be attached to this release shortly.
