+# Advanced Paste – Python Scripts
+
+Advanced Paste supports user-defined Python scripts that transform clipboard content. Scripts are
+discovered automatically from a configurable folder and appear as actions in the Advanced Paste UI.
+
+## Quick start
+
+1. Open the scripts folder — by default `%LOCALAPPDATA%\Microsoft\PowerToys\AdvancedPaste\Scripts`.
+   You can change this in **Settings → Advanced Paste → Python scripts → Scripts folder**.
+2. Drop a `.py` file into the folder.
+3. Define one `advanced_paste_from_<input>_to_<output>` function (see [Writing a script](#writing-a-script)).
+4. Open the Advanced Paste UI (`Win+Shift+V`) — your script will appear in the action list.
+
+> **Important:** Each `.py` file must define exactly one `advanced_paste_from_<input>_to_<output>`
+> function. Scripts with zero or multiple such functions are ignored.
+
+## Writing a script
+
+You write a single Python function whose **name** declares both what clipboard input it accepts
+and what output type it produces.
+No imports from PowerToys are needed — zero setup, zero dependencies on our side.
+
+### Function naming convention
+
+The function name follows the pattern:
+
+```
+advanced_paste_from_<input>_to_<output>(<param>)
+```
+
+**Input types** (what the function receives):
+
+| Input | Parameter | When it runs |
+|-------|-----------|--------------|
+| `text` | `str` — clipboard text | Clipboard has text |
+| `html` | `str` — clipboard HTML | Clipboard has HTML |
+| `image` | `str` — path to temp image file | Clipboard has an image |
+| `audio` | `str` — path to audio file | Clipboard has an audio file |
+| `video` | `str` — path to video file | Clipboard has a video file |
+| `files` | `list[str]` — file paths | Clipboard has files |
+
+**Output types** (what the function produces — declared via `_to_` suffix):
+
+| Output | Effect |
+|--------|--------|
+| `text` | Sets clipboard to text |
+| `html` | Sets clipboard to HTML |
+| `image` | Sets clipboard to image |
+| `audio` | Sets clipboard to audio file |
+| `video` | Sets clipboard to video file |
+| `file` | Sets clipboard to a file |
+| `files` | Sets clipboard to multiple files |
+
+### Return value
+
+The return value is interpreted according to the declared output type:
+
+| Output type | Expected return value |
+|-------------|---------------------|
+| `text` | `str` (or any value — will be converted via `str()`) |
+| `html` | `str` containing HTML |
+| `image` | `str` or `pathlib.Path` pointing to an image file |
+| `file` | `str` or `pathlib.Path` pointing to a file |
+| `files` | `list` of `str`/`pathlib.Path` file paths |
+
+Returning `None` produces an empty result (no-op).
+
+## Examples
+
+### Minimal — uppercase text
+
+```python
+def advanced_paste_from_text_to_text(text):
+    return text.upper()
+```
+
+That's it. No headers required, no imports from PowerToys.
+
+### With optional metadata
+
+```python
+# @advancedpaste:name   Reverse Text
+# @advancedpaste:desc   Reverses clipboard text character by character
+
+def advanced_paste_from_text_to_text(text):
+    return text[::-1]
+```
+
+### Text to HTML
+
+```python
+# @advancedpaste:name   Markdown Table to HTML
+# @advancedpaste:desc   Convert a markdown table to an HTML table
+
+def advanced_paste_from_text_to_html(text):
+    headers = text.splitlines()[0].split("|")
+    return f"<table><tr>{''.join(f'<th>{h.strip()}</th>' for h in headers if h.strip())}</tr></table>"
+```
+
+### Image to text (OCR)
+
+```python
+# @advancedpaste:requires pytesseract
+
+def advanced_paste_from_image_to_text(image_path):
+    import pytesseract
+    return pytesseract.image_to_string(image_path).strip()
+```
+
+### Save text as file
+
+```python
+import os
+from pathlib import Path
+import tempfile
+
+def advanced_paste_from_text_to_file(text):
+    # Use ADVANCED_PASTE_WORK_DIR for WSL compatibility; falls back to temp dir on Windows.
+    out_dir = os.environ.get("ADVANCED_PASTE_WORK_DIR") or tempfile.gettempdir()
+    out = Path(out_dir) / "clipboard.txt"
+    out.write_text(text, encoding="utf-8")
+    return out
+```
+
+### Image processing (image → image)
+
+```python
+import os
+from PIL import Image
+from pathlib import Path
+import tempfile
+
+def advanced_paste_from_image_to_image(image_path):
+    """Convert image to grayscale."""
+    img = Image.open(image_path).convert("L")
+    out_dir = os.environ.get("ADVANCED_PASTE_WORK_DIR") or tempfile.gettempdir()
+    out = Path(out_dir) / "gray.png"
+    img.save(out)
+    return out
+```
+
+### File listing (files → text)
+
+```python
+import os
+
+def advanced_paste_from_files_to_text(file_paths):
+    lines = []
+    for p in file_paths:
+        size = os.path.getsize(p)
+        lines.append(f"{os.path.basename(p)} ({size} bytes)")
+    return "\n".join(lines)
+```
+
+## Header tags
+
+All header tags are **optional**. Tags are placed in comment lines at the top of the script.
+
+| Tag | Description |
+|-----|-------------|
+| `name` | Display name in the Advanced Paste UI. If omitted, the filename is used. |
+| `desc` | Short description / tooltip. |
+| `disabled` | Presence of this tag disables the script (it won't appear in the UI). |
+| `requires` | Declare Python package dependencies (see [Dependencies](#declaring-dependencies)). |
+
+### Example header
+
+```python
+# @advancedpaste:name   My Formatter
+# @advancedpaste:desc   Formats clipboard text as markdown table
+```
+
+To disable a script without deleting it, add:
+
+```python
+# @advancedpaste:disabled
+```
+
+Remove the line to re-enable.
+
+## Declaring dependencies
+
+Use `requires` to declare Python packages the script needs:
+
+```python
+# @advancedpaste:requires PIL=Pillow
+# @advancedpaste:requires cv2=opencv-python-headless numpy requests
+```
+
+Each token is either:
+
+- **`import_name`** — the pip package is assumed to have the same name (e.g. `requests`).
+- **`import_name=pip_package`** — when the import name differs from the pip package
+  (e.g. `cv2=opencv-python-headless`, `PIL=Pillow`).
+
+### Automatic import detection
+
+Advanced Paste also scans the script body for `import` and `from ... import` statements
+and cross-references them against the Python standard library. Any non-stdlib import
+that is not already installed triggers a prompt to install it automatically.
+
+## Security — script trust
+
+The first time a script is executed (or after it has been modified), Advanced Paste
+shows a confirmation dialog. Upon approval the SHA-256 hash of the script is stored.
+Subsequent runs of the unchanged file skip the dialog.
+
+## Error handling
+
+When a script fails, Advanced Paste extracts the Python traceback from stderr and
+displays a user-friendly summary in the UI:
+
+- **ModuleNotFoundError** — identifies the missing module and suggests installing it.
+- **SyntaxError** — shows the file and line number.
+- **Timeout** — shows the configured timeout value (default 30 s; configurable in Settings).
+- **Other errors** — shows the last line of the traceback as a summary, with the full
+  traceback available in the expandable *Details* section.
+
+## Settings
+
+The Python scripts feature uses a **mode selector** (dropdown) with three options:
+
+| Mode | Description |
+|------|-------------|
+| **Disabled** | Python scripts are not active. |
+| **Windows** | Scripts run using a native Windows Python interpreter. |
+| **WSL** | Scripts run inside Windows Subsystem for Linux. |
+
+Each mode maintains its own independent settings (scripts folder, interpreter path, etc.),
+so switching between Windows and WSL does not lose your previous configuration.
+
+### Windows mode settings
+
+| Setting | Description | Default |
+|---------|-------------|---------|
+| Scripts folder | Folder to scan for `.py` scripts. | `%LOCALAPPDATA%\Microsoft\PowerToys\AdvancedPaste\Scripts` |
+| Python interpreter | Path to the Python executable. Leave blank for auto-detection. | *(auto-detect)* |
+
+### WSL mode settings
+
+| Setting | Description | Default |
+|---------|-------------|---------|
+| Scripts folder | Folder to scan for `.py` scripts (Windows path — auto-translated to `/mnt/...`). | `%LOCALAPPDATA%\Microsoft\PowerToys\AdvancedPaste\Scripts` |
+| WSL distribution | Which WSL distro to use (e.g. `Ubuntu`). Leave blank for the default distribution. | *(default)* |
+
+### Scripts list
+
+The Settings page shows a read-only list of discovered scripts. For each script you can see:
+
+- **Name** — from `@advancedpaste:name` tag, or the filename if not set.
+- **Description** — from `@advancedpaste:desc` tag.
+- **Conversion** — the input → output types detected from the function name (e.g. "text → image").
+
+The list is **not editable** from Settings. To change a script's name, description, enabled state,
+or any other metadata, open the script file directly (click the "Open in editor" button) and edit
+the `# @advancedpaste:...` header tags. After saving, click **Refresh** in Settings to reload.
+
+### WSL mode details
+
+When **WSL** mode is selected:
+
+- Scripts are executed via `wsl.exe bash -l -c "python3 ..."` using the configured distribution.
+- The scripts folder remains on the Windows filesystem; paths are automatically translated
+  to `/mnt/c/...` format for WSL access.
+- Package installation uses `pip3 install` inside the WSL environment.
+- Output files from scripts must be written under `/mnt/` (the Windows-mounted filesystem)
+  so they can be accessed from Windows. The runner sets the `ADVANCED_PASTE_WORK_DIR` environment
+  variable to a temp directory under `/mnt/c/...` — use it instead of `tempfile.gettempdir()`
+  when producing file output for cross-platform compatibility.
+
+> **Tip:** If you have Python installed only in WSL (not on Windows), select WSL mode
+> to use your existing WSL Python environment with all its packages.
+
+## Tips
+
+- Each `.py` file must contain exactly one `advanced_paste_from_<input>_to_<output>` function.
+  If you need to handle multiple input types, create separate script files for each.
+- A `.py` file without any matching function is ignored — use this for helper modules
+  that other scripts can import.
+- Scripts can be tested from the command line:
+  ```
+  echo {"format":["text"],"text":"hello"} | python _runner.py my_script.py
+  ```
+- The script's directory is added to `sys.path` at runtime, so you can import sibling `.py`
+  files as helper modules.

+Advanced Paste – Script Runner (V3 Named Function Interface)
+
+This runner is shipped with PowerToys and is NOT user-editable.
+It loads a user script, discovers the single advanced_paste_from_<input>_to_<output>
+function by name convention, calls it with the current clipboard data, and formats
+the return value into JSON on stdout.
+
+Each script must define exactly one function matching the pattern:
+  def advanced_paste_from_<input>_to_<output>(<param>)
+
+Supported input types:
+  - text, html, image, files
+
+Required output types (declared via _to_ suffix):
+  - text, html, image, file, files
+
+Examples:
+  - advanced_paste_from_text_to_text(text: str)    → output is text
+  - advanced_paste_from_text_to_image(text: str)   → output is image
+  - advanced_paste_from_image_to_text(image_path)  → output is text
+  - advanced_paste_from_files_to_text(file_paths)  → output is text
+
+Protocol:
+  - Input:  JSON on stdin (clipboard data from C#)
+  - Output: JSON on stdout (result for C# to set on clipboard)
+  - Errors: stderr (displayed to user on failure)

-    Microsoft ResX Schema 
-    
-    Version 2.0
-    
-    The primary goals of this format is to allow a simple XML format 
-    that is mostly human readable. The generation and parsing of the 
-    various data types are done through the TypeConverter classes 
-    associated with the data types.
-    
-    Example:
-    
-    ... ado.net/XML headers & schema ...
-    <resheader name="resmimetype">text/microsoft-resx</resheader>
-    <resheader name="version">2.0</resheader>
-    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
-    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
-    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
-    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
-    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
-        <value>[base64 mime encoded serialized .NET Framework object]</value>
-    </data>
-    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
-        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
-        <comment>This is a comment</comment>
-    </data>
-                
-    There are any number of "resheader" rows that contain simple 
-    name/value pairs.
-    
-    Each data row contains a name, and value. The row also contains a 
-    type or mimetype. Type corresponds to a .NET class that support 
-    text/value conversion through the TypeConverter architecture. 
-    Classes that don't support this are serialized and stored with the 
-    mimetype set.
-    
-    The mimetype is used for serialized objects, and tells the 
-    ResXResourceReader how to depersist the object. This is currently not 
-    extensible. For a given mimetype the value must be set accordingly:
-    
-    Note - application/x-microsoft.net.object.binary.base64 is the format 
-    that the ResXResourceWriter will generate, however the reader can 
-    read any of the formats listed below.
-    
-    mimetype: application/x-microsoft.net.object.binary.base64
-    value   : The object must be serialized with 
-            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
-            : and then encoded with base64 encoding.
-    
-    mimetype: application/x-microsoft.net.object.soap.base64
-    value   : The object must be serialized with 
-            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
