LimeSurvey News

This is a tough decision for the Limesurvey team, but after lots of discussion we decided to stop all current development.

There will be no more fixes for Limesurvey 1.9x and work on Limesurvey 2.0 will be stopped as well. Instead, we will re-release the old Limesurvey version 1.49 for the following reason: As you might have noticed, the current Limesurvey code base is a mess and it is really hard to maintain because so many features were added during the last months. We analyzed the older versions in detail and agreed that only the old 1.49 version offers a maintainable code base we could continue our work on. This means that the next official Limesurvey release will be version 1.491, unfortunately with lots of features missing (advanced conditions, quick add feature, expression manager,...). We will work hard to implement the missing features the next month and plan to release an updated version with extended conditions this summer.

We are really sorry, but this was no easy decision. We hope to save Limesurvey's future by switching back to a better maintainable code base. Thank you for your understanding!

There have been many forum posts recently asking how to use Expression Manager (EM) and other new features available in Version 1.92+. We have found the best way to learn is to explore working demos.

So, we have updated the documentation to provide easy access to 9 new surveys that test all of the EM and new 1.92 features. For each, we describe which features the survey demonstrates, and provide representative screen shots plus a link to download the survey so that you can import and play with it yourself. The main features demonstrated include:

  • Relevance - with support for more powerful conditional logic than is available via the 1.91+ Conditions editor.
  • Group-level Relevance - if the same conditions apply to all questions in a group, you no longer have to apply them to each question (as was true in 1.91+) - simply specify the relevance at the group-level.
  • Cascading Relevance - this never worked perfectly in 1.91+. Now it does. And, you don't need to specify all of the conditional logic for cascaded questions - they will automatically inherit the conditions from any questions upon which they depend.
  • Piping / Tailoring - easier, more powerful ability to insert answers and question metadata than the old {INSERTANS:xxx} syntax.
  • Conditional Micro-Tailoring - you can dynamically change sentences, such as "Mr." vs. "Mrs.", or "child" vs. "children" based upon prior questions (even ones on the same page). You can even conjugate verbs and decline nouns based upon the gender and/or number of your subjects.
  • Equations - there is a new Equation question type that lets you do complex calculations and store them in the database, all without needing custom JavaScript (thus, this is more powerful and flexible than 1.91+ Assessment functionality).
  • Conditional Validation - traditional validation, like regular expressions, min/max numbers of answers, min/max individual values, and min/max/equals summed values are more robustly supported, with tailored message and CSS styling rather than pop-up messages. Moreover, you can use equations so that your min/max criteria are based upon prior answers. Additionally, these traditional validation styles work for many more question types.
  • (Sub)-Question Level Validation - for most question types, you can now use complex expressions to validate either individual answers or the collection of answers. This lets you do things like ensure that answers are in descending order; specify the maximum responses on a row; or even call external functions to validate the response.
  • Better International Support - you can now use the comma as a radix separator (decimal point) in all question types that require numerical input, plus be sure that the data will be properly stored in the database.
  • Qcode Naming - when you do tailoring, you need to know the proper naming of your variables. One of the surveys includes samples of every question type so you can see how variables should be named.
  • Tailoring using Question Metadata - there are now 16 "dot notation" suffixes available for each question. These let you easily access question metadata (e.g. text, relevance, number, IDs) and answer metadata (e.g. the value stored in the database, the value shown, or the assessment value). One of the surveys has tables showing (for all question types), the values generated for each of these dot notation suffixes.

Please remember:

The easiest way to visualize the entire survey and all of its logic is to use the QA (Survey Logic File) button.
Hovering the mouse over the syntax-highlighted variables shows the variable and/or function definitions.
Clicking on a syntax-highlighted variable opens a new window letting you edit that question.

Enjoy!

 

Today we are bringing you not just one great news but two! LimeSurvey 1.92 is now available for general download. While at the moment it is not yet available on the ComfortUpdate we will make it available within the next two weeks.

As you may already know that the biggest change on this release is the availability of the great Expression Manager engine coded by Thomas White. Before you upgrade please have a look at our upgrade notes, as there might be some issues with your existing surveys that need to be resolved before/after upgrade.

The other news is that version 2.0 alpha 3 is now available. It incorporates all features from LimeSurvey 1.92 and adds several new ones. Version 2.0 is now based entirely on the Yii PHP framework and thus makes extending LimeSurvey at a later time much easier. Please download and test it out and let us know if you see any problems.
