// This is a fork of electron-context-menu@0.15.0. We need to fork it because
|
|
// the latest version only runs from the main process and we need it in the
|
|
// renderer process. It also has a dependency to electron-is-dev which also only
|
|
// runs in the main process.
|
|
//
|
|
// In fact we almost don't use any features of electron-context-menu, which is
|
|
// just a wrapper over Electron's own native context menu but with more bugs, so
|
|
// we should get rid of it, but for now this is good enough as a quick fix.
