Hi all!
Regarding the performance issue:
sounds like a realistic scenario with the current implementation, the
DOM is a very slow thing ;)
The problem is that currently the whole project tree is rendered as a
HTML list: each instance in a project, for example a file or a folder,
is represented via an `li` element. A folder has subelements,
represented in a `ul`element inside the `li` element, you got it...deep
tree structure. Solution would be a progressive rendering: the children
of an element are only rendered when opened. Should not be too difficult
to implement, I will have a look at it tomorrow. Thanks for the hint,
already thought about it a time ago but never tested it with a bigger
workspace.
However, if not just the rendering is the problem, but the passing and
processing of the JSON object...I really hope thats not the case...
I will do some test runs tomorrow and keep you up-to-date.
Regarding the "I cant see anything" issue:
The following text is copied from the README.md in
de.fu_berlin.inf.ddp.ui.frontend:
# Development workflow
If you make any changes in a `.js` or `.jade` file you have to build the
JavaScript application in order to see the changes in action.
# Build with NPM
Navigate to `de.fu_berlin.inf.dpp.js/html/` and run `npm run build`.
## Tasks of the build process
- compile JADE-templates to plain old JavaScript functions (for more
information about JADE visit http://jade-lang.com/)
- creating a `bundle.js` which contains all internal JavaScript files, external
JavaScript frameworks and the template functions
More tasks are planned for the furture, for example unit testing and code
linting.
# Install NPM
To run scripts with NPM you have to install NodeJS and NPM.
For more information about installing NodeJS and NPM see nodejs.org.
That is not very up-to-date but holds true all in all, expect the path
to the html folder which is now:
de.fu_berlin.inf.dpp.ui.frontend/html
Should be sufficient to build and run the application in Eclipse, in
IntelliJ there is a implementation of the WorkspaceRoot/Workspace
(Matthias knows that in more detail, I think) missing.
Best,
Basti
