I guess it’s all over the news right now, that the latest service pack (SP2) for MS Office 2007 will enable Office to import and export ODF natively. This blog piece by Doug Mahugh touches on the word processor part of their ODF support. I haven’t yet tried it myself, but judging by Doug’s blog article it looks pretty impressive.
But, being more of a spreadsheet person, I’m personally more interested in how it fares in Excel to Calc interoperability. Since their ODF support is on ODF 1.1, which predates the on-going OpenFormula specification work, I’d be interested to see how compatible the formulas are. Technically speaking, as of ODF 1.1, interpreting formula expressions was pretty much application-specific, so I would not be surprised even if they are not compatible at all. But we’ll just have to see.
Either way, I find this news very encouraging. This is undoubtedly a big step toward proliferation of ODF as a practical document exchange format.
Just checked this piece into the master branch of the go-oo repository. It allows traversing to precedents and dependents of a cell by Ctrl-[ and Ctrl-] key strokes, respectively. It is similar in concept to the existing Detective functionality, but while Detective graphically shows the precedents and dependents of a current cell, this new functionality physically moves the cursor to the precedent and dependent cells. Similar functionality already existed in Excel, so this is one of those interoperability features and, for some spreadsheet users, the ability to jump to precedents/dependents is apparently very important for their productivity.
No feature is complete without screenshots. So, here they are. :-)
In the first example, the cell currently selected contains references to three cells and one cell range in its formula expression. I’m showing the precedent traces here just to show their relationship visually.
When you hit Ctrl-[, it highlights all its reference cells (a.k.a precedents) and moves the cursor to the first precedent.
Once the cells are highlighted, you can easily navigate through the highlighted cells by hitting the Enter or Tab key.
There is one caveat. When the expression includes references to cells outside of the current sheet, the ones that are not on the current sheet are ignored. The only exception to this rule is when the first reference points to a cell in another sheet, in which case it jumps to that external-sheet cell while the rest of the references are ignored even if they are on the current sheet. If that reference is in another document (i.e. external reference), it opens that document then sets the cursor to the referenced cell position provided that the document is available at specified location in the file system.
Traversing to dependents also works in a similar fashion. Consider the following example
where current cell is referenced by multiple other cells. Again, I’m showing the dependency traces to display their relationship graphically. When you hit Ctrl-], it highlights all its dependent cells and moves the cursor to the first dependent cell.
Similar to the precedent jump, there is a caveat; when the cell is referenced by cells on multiple different sheets including the current sheet, only those cells on the current sheet are highlighted and the rest are ignored. But unlike the precedent jump, there is no exception to this rule.
That’s it folks! I hope you find this new functionality useful. And as always, please report back any problems you may encounter so that I can fix them. Thank you very much, ladies and gentlemen. :-)
Just checked into the master branch of go-oo repository (oh BTW we just switched our repository from svn on gnome.org to git on freedesktop.org) is a minor enhancement in DataPilot, to allow the users to filter results by field members directly from the field buttons in the table output. The following screenshot will tell you the change I just made:
The new field buttons also provide visual feedback on fields that are filtered; the same way the autofilter buttons already do. This way it’s visually obvious to the users which fields are currently filtered.
I call this a “minor” enhancement, simply because it doesn’t provide a new functionality per se; the same filtering functionality was already present but hidden deep beneath multiple layers of dialogs. You needed to go from the datapilot layout dialog (the main dialog), open up the field dialog for the field you want to filter results by, and then finally the field options dialog to get to the Hide items list in that dialog. This enhancement will push that functionality up-front and make it more accessible to the users, along with some visual feedback.
Anyway, this one made it into 3.1, so testing and feedback is greatly appreciated. :-)
