Update page url by adding user state as user navigates in model about webgme HOT 1 CLOSED

Url encoding of the state

• project: project name
• branch: branch name
• commit: commit hash, used if branch is not given
• node: object to load in the visualizer
• visualizer: visualizer name to open
• aspect: aspect name in the visualizer if applicable
• selection: comma separated list of selected object (node) ids

Notes

Url may exceeds the maximum length limit. In the future we should be able to generate short urls and save it on server side. Server will server the state information then.

Caveats

the back/forward button (history) never followed user navigation and events in visualizers, except in the ModelEditor (a.k.a. composition view)

Only the model editor works for the visualizer and aspect settings

Example urls

• /?project=test1&branch=master&node=&visualizer=ModelEditor&aspect=All
• /?project=test1&commit=<commit_hash>&visualizer=ModelEditor&aspect=All
• /?project=test1&branch=master&node=&visualizer=ModelEditor&aspect=Aspect2
• /?project=test1&branch=master&node=&visualizer=METAAspect
• /?project=test1&visualizer=ModelEditor&aspect=All&selection=%2F1801445538,%2F325565474

Testing

• no project is given
• given project does not exist
• no branch name is given
• branch does not exist
• node does not exist
• commit does not exist
• visualizer does not exist
• aspect does not exist
• selection contains nodes that do not exist
