This was removed in f8f9334, but it occurred that
the method is used productively by some of the clients.
This commit restores the method as part of public API.
Use `Viewer#importDefinitions` to import previously
parsed definitions. Now it is also possible to pass
the diagram or diagram id to be rendered during
graphical import.
This adds a method to switch displayed diagram without reimporting
xml via
```
var viewer = new Viewer({ container: container });
viewer.importXML(xml, diagramId, done);
var diagrams = viewer.getDefinitions().diagrams;
viewer.open(diagrams[1], done);
```
This introduces a new parameter to `Viewer#importXML`
which enables to choose the diagram to display.
```
var viewer = new Viewer({ container: container });
viewer.importXML(xml, diagramId, done);
```
Closes#87
This makes the viewer emit events during SVG and XML export.
These events allow others to hook in, i.e. to trigger additional _save_
actions.
Closes#811
* use ES6 import / export
* UTILS: export individual utilities
* TESTS: localize TestHelper includes
BREAKING CHANGE:
* all utilities export independent functions
* library sources got ported to ES6. You must now use
a ES module bundler such as Browserify + babelify or
Webpack to consume this library (or parts of it).
Async utilities properly propagate _all_ errors to the
specified _done_ callback. Failing in _done_ does not
re-invoke it.
Adjustments made in
* Viewer#importXML
* Viewer#saveSVG
* Importer#importBpmnDiagram
Tests cleaned up to remove un-necessary `if (err) { ...` snippets.
This improves the import and export of BPMN 2.0 XML documents
+ improves di prefix collision handling
+ proper deconflicting of prefixes during export
+ validate and detect non-BPMN root elements
+ replace underlying XML parser for higher speed and smaller
bundle size
+ pass parse warnings with errors
NOTE:
* some error messages on broken XML may have changed
due to changes in the underlying XML parser
Closes#655
BREAKING CHANGE:
* Viewer / Modeler do not attach to `body` anymore per
default. Use `new Viewer({ container: 'body' })` to
restore the old behavior.
This commit adds more life-cycle events users can
plug into during xml parsing and rendering:
* import.parse.start
* import.parse.complete
* import.render.start
* import.render.complete
* import.done
Some other events had to go because of that, namely
* import.start
* import.(success|error)
BREAKING CHANGE:
* the event import.start got renamed to import.render.start
* the events import.success and import.error got removed
in favour of import.render.complete (passing err, warnings)
* simplifies event handling
* relies on Diagram#clear to reset the diagram before
successive imports
* allows diagram services to be re-used across imports
* allows diagram services to be injected (or retrieved)
before import
Closes#237
