Version History

Added

• •With "Complete command names" on, commands you installed with Homebrew appear with their package's description.
• •With "Learn unknown commands from --help" on, a command's own zsh completion file fills in its subcommands and options.

Fixed

• •Commands installed while Sill was running did not appear until Sill was restarted.

Added

• •With "Complete command names" on, your zsh aliases appear alongside commands with what each one runs, as with gco for git checkout.
• •A simple alias keeps the completions of the command it stands for, so gco lists your branches the same way git checkout does.
• •Git aliases appear after git, and after an alias such as g, so git co lists your branches when co is set to checkout.
• •Aliases appear in terminal tabs opened after this update.

Fixed

• •Choosing a path under ~/ inserted a stray backslash in front of it.
• •Folder and file names with spaces or quotes were inserted without escaping for some commands.

Added

• •Typing . offers ./ on top, so Return runs the line as typed.

Changed

• •The menu bar icon is drawn a little thinner, closer to the weight of the system's own icons.

• •The Settings window could no longer be dragged after a switch in it was flipped.

• •The menu bar icon is now Sill's own: a prompt with a suggestion card, like the app icon.

• •The app icon's background looked flat in the Dock and Finder. It now shows its gradient.

• •Fixed folder suggestions not appearing for a path such as cd ../ after the previous update.

• •Fixed the popup flashing for a moment when pressing Return on a command recalled from history with the arrow keys.

• •Closing Settings or the welcome window now returns you to the app you were using, so other apps' shortcuts keep working right away.

• •A command recalled from history with the arrow keys or ⌃R opens no popup, so the next arrow keeps moving through history. Typing on that line brings the popup back.

• •In VS Code, the popup stayed in the wrong place and vanished after an editor group was added or removed beside the terminal.
• •In VS Code, the popup follows the terminal more quickly when the layout changes while it is open.

• •In Ghostty, the popup appeared at the bottom of the window after the screen was cleared with ⌘K, then vanished.
• •In Ghostty, the popup keeps its place on a line that contains Korean or other wide characters.

• •Fixed steady processor use that began once Settings had been opened and went on after the window was closed.

Changed

• •In commands that list paths, such as cd, the folder list narrows with every letter as you type.
• •Items closest to what you are typing come first, ahead of ones you picked before.
• •Scripts from package.json list above files and folders whose names start the same way.

Fixed

• •Pressing Return right after the last letter completes the word you typed.

• •In VS Code the popup opens at the current cell and holds still while you type.
• •Text in the highlighted row turns dark on light accent colors such as yellow.
• •Holding an arrow key stops at the end of the list, and a single press at the end wraps round.
• •Terminal tabs opened after this update reconnect on the next keystroke when Sill is quit and relaunched, or updated.

• •A small "Loading…" row sits at the bottom of the popup while a list is still on its way, as with npm install re.
• •Typing .. offers ../ like any other folder, and with cd ../ it stays on top so Return goes up one level.
• •Newer gh commands are completed, such as gh auth switch and gh auth token.
• •With "Learn unknown commands from --help" on, a command that already has a definition also gains what that definition lacks.

• •Completing a folder no longer adds a trailing slash; typing one lists what is inside.
• •If the highlighted item is exactly what you typed, Return runs the command. ls runs even with lsof in the list.
• •Typing an alias puts its command first: npm i lists install above info and init.
• •Fixed a stray space after some completions.

• •Splitting a pane or resizing the window no longer throws the popup off: it finds the caret again on the very next keystroke, with no Enter needed.
• •Clearing the screen with ⌘K is handled the same way.
• •Fixed a runaway where stray terminal replies could flood the prompt with text until you pressed ^C.
• •In Ghostty the popup now follows the caret from the screen itself, so a wrapped line above the prompt no longer shifts it.
• •A terminal that answers its first query slowly, like a freshly opened pane, now gets a full second instead of losing the whole first line.

• •Sill now speaks Korean: Settings, onboarding and the menu follow your system language.
• •Type the first letter and Sill can offer the command itself, with a line on what it does. Switch on "Complete command names" in Settings.
• •Matching is fuzzy now: "chk" finds checkout and "rb" finds rebase, and the letters that matched are shown in the list. Exact and prefix matches still come first.
• •After completing a word, your terminal's syntax highlighting updates right away instead of leaving it half-coloured.
• •The list's icons no longer change with your system language.
• •The "Check for Updates" button in Settings is its own size again.

• •Ghostty and cmux now get completions too, alongside Terminal.app, iTerm2 and VS Code.
• •Commands the definitions don't cover can now be learned from their own help text. Switch it on under Specs in Settings, and only real programs are ever run.
• •Completing a word no longer leaves a space behind it, and the list closes so your next keystroke goes straight to the shell.
• •When what you typed is already the whole word, Return runs the command instead of completing it.
• •The list lines up with your cursor the same way in every terminal now.
• •Arrowing to the top or bottom of a long list keeps the highlighted row clear of the edge instead of tucking it under.
• •Fixed the stray characters that could appear at your prompt when a terminal answered slowly.
• •Fixed the pale corners that showed around the popup.

• •Initial release: IDE-style autocomplete for Terminal.app and iTerm2. A popup at your cursor with subcommands, options, files, and branches for the command you're typing, each with a short description.
• •Arrows choose, Tab or Return inserts, Esc dismisses. With the popup closed, Return runs your command as usual.
• •Completion definitions for hundreds of CLIs from the open-source withfig/autocomplete corpus, downloaded on first run and refreshed daily.
• •Dynamic suggestions (git branches, npm scripts, file paths) computed locally in the session's working directory.
• •A one-line zsh integration installed from the app (and cleanly removable in Settings); ~/.zshrc is backed up first.
• •Sparkle keeps the app up to date.
