"Qlikview Components" Open Source Project

rwunderlich — Thu, 01 Dec 2011 18:45:55 GMT

Today I launched an open source project named "Qlikview Components". My goal is to simplify some of the common scripting tasks and develop a community supported standard for scripting.

Here's the mission statement:

Qlikview Components (QVC) is a library of script subroutines and functions. The mission of Qlikview Components is:

Implement scripting best practices encapsulated by a simple and stable API.
Improve the speed and quality of script development.
Create common ground between script developers.

You can find the project at http://qlikviewcomponents.org. There you'll find links to downloads, forums and an issue tracker.

The example and documentation qvw files in the project are not Personal Edition enabled. PE users can use QVC, they just can't open the documentation yet.

Feedback welcome.

Where would you like general feedback on the project? Such as, for example, some thoughts on issues with and enhancements to the calendar? I'm guessing the user forum of the project? There's also an issues section, but I'd think that would be for very specific things, kind of like a bug tracker?

Please use the project User Forum for how-to questions, enhancement requests and general discussion.

Use the Issues section only to report defects.

Thanks for posing the question. I'll add this clarification to the project home page.

Hi Rob,

Great initiative. I could think of several additions to this project. I'm originally a technical SAP consultant (since 1987) and mainly working on SAP related QV implementations. There's several things I could think of having in your project specifically related to SAP, for instance currency conversion, which is pretty specific in SAP, but once scripted, used over and over again.

Regards,

Rob

A new version, 5.0, is available for download from

http://code.google.com/p/qlikview-components/downloads/list

Changes for this version.

- Added new Sub, Qvc.DataLineage.

- Fixed Issue 22, sample CalendarExtFields.qvs should use WeekYear() instead of Year().

- Issue 23. Removed min/max reporting message from Qvc.IncrementalStore. Finding the values added significant runtime to large tables.

Qvc.DataLineage builds a table of the sources used in a qvw. Can be used to automatically include a data lineage chart in a qvw. It requires that the QVW be reloaded in QV10 SR2 or better.

Note there is an outstanding bug in QV11 where old lineage data is not being dropped from the QVW. So you may not have accurate results from a V11 QVW if you remove a data source -- until this bug is corrected.

Hi Rob,

First of all, great job! Second, my question: if is possible to present the documentation in PDF for PE users?

Thanks for all,

Yago
