Omacus v0.1.6

What's new

• README: say how Omacus is pronounced, matching the video
• Add the launch video to the site and README
• Add the launch video's build pipeline
• Fix a Windows-only lint in the updater's private folder
• Use https in the install one-liner everywhere; docs for the new shortcut
• Make deleting a sheet undoable, and never lose a save quietly
  • Deleting a sheet is Ctrl+Shift+Delete (Ctrl+Delete deletes a word in the
    editor) and shows Undo; the trash gets the text as it was, unsaved edits
    included
  • A failed save shows a message instead of retrying silently forever
  • Saves are flushed to disk before replacing the file, with temporary names
    unique to each window
  • The settings check and the help examples no longer run every frame
• Harden the installer and the updater
  • Piped from curl, the installer never trusts files in the current folder (a
    shared /tmp could hold someone else's "release"), runs everything from
    main() so a cut-off download does nothing, refuses to run as root, and
    only fetches over HTTPS
  • macOS: updates replace the exact app bundle (even renamed), copying beside
    it first so a failed copy never leaves no app
  • Hyprland keys are validated before they go into the Lua config, backups are
    restored by copying (symlinked configs survive), and existing config errors
    no longer trigger a rollback
  • The updater downloads the release's own install.sh (or Windows zip) from
    GitHub for that version, checks it against the release's SHA256SUMS, and
    runs it from a private folder; the Windows swap cleans up on every failure
  • zip 9 (RustSec advisories in 2.x extraction code, which Omacus didn't use);
    network requests have timeouts
• Fix silently wrong answers found in an audit
  • Numbers in labels no longer multiply into the amount: "Day 3 $50" and
    "iPhone 15 $799" give $50 and $799, not $150 and $11,985
  • half, twice, double, triple, a third, a quarter and percent count:
    "half of 50" is 25, "50 percent off 80" is 40
  • I, a, an, the, at are prose unless they follow a number: "I spent $40" is
    $40 (not imaginary), "$4 a day" is $4 / day, "3 pizzas at $12" is $36
  • A time of day that isn't a conversion ("Movie at 7pm") gets no answer
    instead of picometres; lines with until/since/ago get none instead of a guess
  • Big numbers keep every digit, tiny ones show as 1e-12 instead of 0,
    negative money reads -$5, and 0x10 stays hex
  • "$1200 / 12 in EUR" works again; labels may contain digits ("Item 2:")
  • Adding days to a time shows the date, and dates outside this year show it
  • GMT is a fixed offset; huge durations give no answer instead of crashing
  • prev on the first line gets no answer; very long lines are skipped

Install

Platform	Download
macOS (Apple Silicon & Intel)	omacus-macos-universal.dmg
Windows (x64)	omacus-windows-x86_64.zip
Ubuntu / Debian	omacus-linux-x86_64.deb
Fedora / openSUSE	omacus-linux-x86_64.rpm
Omarchy / Arch / any Linux	omacus-linux-x86_64.tar.gz or the installer below

Omarchy (installs the app, then offers a keybind, SUPER + CTRL + ALT + = by default, and a floating window rule):

curl -fsSL https://omacus.com/install | bash

Any other Linux (installs to ~/.local/bin with a launcher entry):

curl -fsSL https://omacus.com/install | bash

Ubuntu / Debian: sudo apt install ./omacus-linux-x86_64.deb
Fedora: sudo dnf install ./omacus-linux-x86_64.rpm

macOS: open the .dmg and drag Omacus to Applications. It isn't notarized yet, so the first
time right-click the app and choose Open, or run xattr -dr com.apple.quarantine /Applications/Omacus.app.

Windows: unzip and run omacus.exe. If SmartScreen warns about an unknown publisher, choose
More info → Run anyway. It works from a terminal too: omacus.exe "$100 in INR".

Checksums are in SHA256SUMS.txt.
