hypsnip

Rust implementation of steipete/Trimmy for Waybar/Hyprland and, more generally, Wayland compositors.

What it does

• Lives in your Waybar or in the terminal (pipe to hyprsnip)
• Watches the clipboard, and, when it looks like a shell command, removes newlines (respects \ continuations) and rewrites the clipboard automatically
• Strips leading shell prompts (#/%/>/$) when the line looks like a command, while leaving Markdown headings untouched
• 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 upgrade copy from a blog post.
  • High: flattens almost any multi-line text that could be a command. Example: a quick two-line ls + cd copied from chat.
• Optional "Keep blank lines" so scripts with intentional spacing stay readable.
• Optional "Remove box drawing chars (│┃)" to strip prompt-style gutters (any count, leading or trailing) and collapse the leftover whitespace.
• "Paste Trimmed" button + hotkey trims on-the-fly and pastes without permanently altering the clipboard (uses High aggressiveness); shows the target app (e.g., “Paste Trimmed to Ghostty”) and strikes out removed chars in the preview.
• "Paste Original" button + hotkey pastes the untouched copy even after auto-trim.
• Optional "Launch at login" toggle (installs systemd user service).
• 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.

Aggressiveness levels & examples

• Low (safer) — needs strong command cues (pipes, redirects, continuations).
  Before:

  ls -la \
    | grep '^d' \
    > dirs.txt
  

  After: ls -la | grep '^d' > dirs.txt

• Normal (default) — README/blog-ready: handles typical multi-line commands with flags.
  Before:

  kubectl get pods \
    -n kube-system \
    | jq '.items[].metadata.name'
  

  After: kubectl get pods -n kube-system | jq '.items[].metadata.name'

• High (eager) — flattens almost anything command-shaped, plus the manual “Paste Trimmed” hotkey always uses this level.
  Before:

  echo "hello"
  print status
  

  After: echo "hello" print status

• Prompt cleanup — copies that start with # or $ are de-promoted when they look like shell commands, e.g. # brew install foo → brew install foo; Markdown headings like # Release Notes remain untouched.

  Before:

    ┃  Can you plan out the application @README.md but in
  ┃  rust?
  

  After:

  Can you plan out the application @README.md but in rust?
