+# Gui2TopoLib
+
+This project was generated with [Angular CLI](https://github.com/angular/angular-cli) version 7.0.4.
+
+It is the Topology View of the ONOS GUI. It has been extracted out in to its own
+library here to allow it to be used by other projects.
+
+This deliberately has no dependency on the ~/onos/web/gui2 project
+It does depend on the ~/onos/web/gui2-fw-lib - the Framework is common to all apps
+
+The view is made up of a hierarchy of Angular components - starting at the top 
+with Topology Component
+
+Extensive use is made of SVG to generate the view - especially the layers, nodes
+and links. Each of these are components that are meant to be used inside an SVG
+element and so have the suffix SvgComponent. Other like panels are plain Html
+
+```
+TopologyComponent
+|   (layers)
+|-- NoDeviceConnectedSvgComponent
+|-- BackgroundSvgComponent
+|  |-- MapSvgComponent
+|-- GridsvgComponent
+|-- ForceSvgComponent
+|  |-- DeviceNodeSvgComponent
+|  |-- HostNodeSvgComponent
+|  |-- LinkSvgComponent
+|  |-- SubRegionNodeSvgComponent
+|
+|   (panels)
+|-- DetailsComponent
+|-- InstanceComponent
+|-- SummaryComponent
+|-- ToolbarComponent
+|-- MapSelectorComponent
+```
+
+The purpose of the tester application is to
+a) show how the Topology View can be easily reused
+b) Allow a developer to run the GUI with Angular CLI tools (ng serve) without
+   all of the baggage of the whole ONOS GUI
+        
+## Development server
+
+Run `ng serve` for a dev server from ~/onos/web/gui2-topo-lib. Navigate to `http://localhost:4200/`.
+When a change is made to the library code, it has to be built again
+`ng build gui2-topo-lib && ng serve`
+
+This requires the following manual steps
+* Make directory `fw/widget` in `~/onos/web/gui2-topo-lib/projects/gui2-topo-lib`
+* Copy  ~/onos/web/gui2-fw-lib/projects/gui2-fw-lib/src/lib/widget/panel*.css in to this
+* Copy directory `~/onos/web/gui/src/main/webapp/data` in
+    to `~/onos/web/gui2-topo-lib/projects/gui2-topo-tester/src/data`
+* Change (temporarily) web/gui/src/main/java/org/onosproject/ui/impl/UiWebSocket.java
+to remove the check for sessionToken (lines 249 -251)
+* Run ONOS `ok -- clean debug` and enable the GUI2 application
+
+## Code scaffolding
+From inside ~/onos/web/gui2-topo-lib/projects/gui2-topo-lib
+run `ng generate component component-name` to generate a new component.
+ 
+You can also use `ng generate directive|pipe|service|class|guard|interface|enum|module`.
+
+## Build
+To build just the library run `ng build gui2-topo-lib` This will always be built
+in Prod mode
+
+Run `ng build` to build the project. The build artifacts will be stored in 
+the `dist/` directory. Use the `--prod` flag for a production build.
+
+## Running unit tests
+
+Run `ng test` to execute the unit tests via [Karma](https://karma-runner.github.io).
+
+## Running end-to-end tests
+
+Run `ng e2e` to execute the end-to-end tests via [Protractor](http://www.protractortest.org/).
+
+## Further help
+
+To get more help on the Angular CLI use `ng help` or go check out the [Angular CLI README](https://github.com/angular/angular-cli/blob/master/README.md).

+     It is mapped to a 2000x1000 SVG grid with -500,0 at the top left
+     (The SVG viewbox of ONOS is 1000x1000 - for the geo grid we wanted
+     to keep it the same height 1000 representing +75 latitude down to
+     -75 latitude, but double the width. Why 75? There's no city in the
+     world above 70 - Murmansk)
+     The 6.66 represents 1000/150 and the 5.55 represents 2000/360
+     The reason for the difference is that mercator projection widens
+     countries in the northern and southern extremities, and so
+     the map is squashed horizontally slightly here to compensate
+     (with no squashing the width would be 2400)-->
