Notes

• vscode-ide-purescript is a thin wrapper, most functionality is in purescript-language-server
• The project uses PureScript versions installed in the individual project directories
  • There may be more preferable versions than the ones defined in ENV, consult the docs and and config for each project
• vscode notifies the language server when files need to be processed adding features that process additional file types requires a change inside of vscode-ide-purescript

fileEvents:
    [ workspace.createFileSystemWatcher('**/*.purs')
    , workspace.createFileSystemWatcher('**/*.js')
    ]

• If building inside of VSCode, issues will likely be visible in the VSCode "terminal" panel
• If builds work correctly via Make, but not inside VSCode, check that you're using local versions of npm and associated tools:
