Failed to open browser from WSL

environment

• Windows 10
• wsl2 ubuntu:18.04
• Scala 2.13.4
• plotly-scala 0.8.0

log

java.io.IOException: Cannot run program "xdg-open": error=2, No such file or directory
  java.lang.ProcessBuilder.start(ProcessBuilder.java:1128)
  java.lang.ProcessBuilder.start(ProcessBuilder.java:1071)

  plotly.Plotly$.plot(Plotly.scala:175)
  plotly.Plotly$TraceSeqOps$.plot$extension(Plotly.scala:296)

This is probably because sys.props.get("os.name") (Plotly.scala L162) returns linux, but WSL can not launch default browser of host OS by xdg-open command.

Note

Workaround

If you want to programatically open plotly.html from WSL with default browser of host OS, install wsl-open and set symbolic link.

npm install -g wsl-open
sudo ln -s $(which wsl-open) /usr/local/bin/xdg-open
