Manim Notebook

VSCode extension for replicating Grant Sanderson's manim workflow for Sublime Text from this video

Note this extension is specifically for 3b1b's original manim library, NOT the community version.

Example usage

1. Install manimgl, make sure that the command manimgl works in your terminal
2. Open your manim file (e.g. scene.py) in VSCode
3. Place your cursor where you want to start the scene, on a line of code within the construct method in a scene class
4. Run the VSCode command: cmd+shift+p -> Manim Notebook: Start scene at cursor
   (This command runs manimgl scene.py NAME_OF_SCENE -se <lineNumber> in your terminal)
   In the upper-right of your screen - the manim interactive video will appear.

Then you can do either:

• Write some comments which start with: ##.
  The clickable "Preview Manim Cell" buttons will appear above each such comment.
  Clicking on one will run it.
  It is equivalent to: cmd+shift+p -> Manim Notebook: Preview active Manim Cell

• Place your cursor on some line (or highlight several lines),
  cmd+shift+p -> Manim Notebook: Preview selected Manim code
  This will run the selected lines.

Keybord shortcuts

You can use the default keyboard shortcuts for these commands, or assign your own.

• the default shortcuts all start with cmd+'
• use cmd or ctrl depending on your OS

All current commands are:

• Manim Notebook: Start scene at cursor.
  Shortcut: cmd+' cmd+s
• Manim Notebook: Preview active Manim Cell.
  Shortcut: cmd+' cmd+e
• Manim Notebook: Preview selected Manim code.
  Shortcut: cmd+' cmd+r
• Manim Notebook: Remove all objects from scene.
  Shortcut: cmd+' cmd+c
• Manim Notebook: Quit preview.
  Shortcut: cmd+' cmd+w

Demonstration

The resulting workflow can look like Grant's 🥳

Customization

• There are some extension settings that you can tweak: just press Ctrl/Cmd + , in order to open the settings and search for Manim Notebook.
• Customize the color of the Manim Cells in your settings.json file as described here in the VSCode docs. Why not go for a more red-ish color? 🎨

Troubleshooting

If you encounter an issue, search for some related keywords first in the issues. If you can't find anything, feel free to open a new issue. To analyze the problem, we need a log file from you:

• Open the command palette Ctrl+Shift+P (or Cmd+Shift+P)
  and use the command Manim Notebook: Record Log File.
• Then set the log level by searching for Manim Notebook and selecting Trace.
• Now reproduce the issue, e.g. by running a command that causes the problem or previewing a certain Manim cell etc.
• Once you're done, click on the button in the status bar (bottom right) to finish recording. The log file will be opened afterwards.
• Drag-and-drop the log file into the GitHub issue text field (as a file, i.e. please don't copy-paste its content because this would make it hard to read).
