Behavior​

  • WasmEdge installation appends all the files it installs to a file which is located in the installer directory named env with its path as $INSTALLATION_PATH/env.

Shell and it's configuration​

  • Source string in shell configuration is given as . $INSTALLATION_PATH/env so that it exports the necessary environment variables for WasmEdge.
  • Shell configuration file is appended with source string if it cannot find the source string in that file.
  • Currently, it detects only Bash and zsh shells.
  • If the above shells are found, then their respective configuration files $HOME/.bashrc and $HOME/.zshrc are updated along with $HOME/.zprofile and $HOME/.bash_profile in the case of Linux.
  • In the case of Darwin, only $HOME/.zprofile is updated with the source string.
