| # This contains additional Skia helpers for use with the CodeLLDB debugger extension to VSCode |
| # https://github.com/vadimcn/vscode-lldb |
| |
| # To use these features, run the following command at the (lldb) prompt within VSCode: |
| # |
| # command script import (your-skia-local-path)/platform_tools/debugging/lldb/skiavis.py |
| # |
| # This can be automatically enabled at the start of every debugging session by adding that command |
| # to the "initCommands" of your launch configuration, as explained here: |
| # https://github.com/vadimcn/vscode-lldb/wiki/Data-visualization |
| # |
| # From my testing, the instance of LLDB that runs within CodeLLDB does not invoke ~/.lldbinit, |
| # so adding the command there will not work. (In addition, this script uses modules that won't |
| # be present in command-line LLDB). |

| # Helper function to draw an SkPath as an SVG document within VSCode |
