Autocompletion issues

[imagejan]

When running jupyter notebook with scijava-jupyter-kernel 0.4.0 on Mac OSX, just typing a few characters and then Tab will crash the kernel. This apparently only happens before the first cell was executed.

On subsequent trials, autocompletion with Tab seems to work, but when showing multiple options, it always displays the entire content of the cell up to the cursor position (together with the suggested completion, of course). In my trials, it once happened that the #! annotations at the start of the cell were erased (replaced by empty lines) by the autocompletion, but I currently cannot reproduce.

On Windows 7, scijava-jupyter-kernel get updated to version 0.4.0 without problems, but in a new notebook, the kernel is still displayed as "Scijava" instead of "SciJava" (with camel case), and hitting Tab leads to the entire cell contents being replaced by

Autocompletion does not work yet.

The first bug is fixed with dbd866a.

For the second bug, I just realized that the string returned is the entire cell and not only the current line where TAB is triggered. I'll try to improve the behavior.

On windows try to remove all your scijava kernel and reinstall it from scratch. It looks like a mix between an old installation.

I tried a fix for the second bug but it requires more work.

In short the String code returned here contains all the code of the cell and index is the index number where TAB has been triggered. What needs to be done:

• Split the String in List<String> lines.
• Calculate the current line number and store it as a String.
• Calculate the index in the current line.
• Use the above in completer.autocomplete(code, index, scriptEngine).

Then it should magically work.

I won't be able to fix that before few weeks probably.

You were right, I still had the old SNAPSHOT jar in my anaconda environment from previous tests, and the 0.4.0 version was installed next to it. Thanks for the hint.

• Split the String in List<String> lines.

Maybe also splitting at the last space character would make sense.
Anyhow, maybe this is not even necessary, as long as the displayed choices are not repeating the whole code but just the relevant object/method/field...

Autocompletion has a problem with multiple lines cells. It should be fixed.
