"Paste once, run once." — Trimmy flattens those multi-line shell snippets you copy so they actually paste and run.
- Lives in your macOS menu bar (macOS 15+). No Dock icon.
- Watches the clipboard and, when it looks like a shell command, removes newlines (respects
\continuations) and rewrites the clipboard automatically. - Aggressiveness levels (Low/Normal/High) to control how eagerly it detects commands:
- Low: only flattens when it’s obviously a command. Example: a long
kubectl ... | jq ...multi-line snippet. - Normal (default): balances caution and helpfulness. Example: a
brew update \ && brew upgradecopy from a blog post. - High: flattens almost any multi-line text that could be a command. Example: a quick two-line
ls+cdcopied from chat.
- Low: only flattens when it’s obviously a command. Example: a long
- Optional "Keep blank lines" so scripts with intentional spacing stay readable.
- Manual "Trim Clipboard Now" button if you just want to force a flatten.
- Optional "Launch at login" toggle (macOS 13+ via SMAppService).
- Auto-update via Sparkle (Check for Updates… + auto-check toggle; feed from GitHub Releases).
- Uses a marker pasteboard type to avoid reprocessing its own writes; polls with a lightweight timer and a small grace delay to catch promised pasteboard data.
- Safety valve: skips auto-flatten if the copy is more than 10 lines (even on High) to avoid mangling big blobs.
