But when accessing the data from JS, row-based access may make a lot of sense, in many cases, and beyond rkwarddev. Consider whether (some of) this can be implemented in plain JS. In theory we can include simple and useful JS functionality in common.js (which is included in all plugins). I'm not quite sure what exactly should go in there, and so I've been rather reluctant about adding anything, there, but it's an option to keep in mind. (Or we could provide JS libraries for plugins to include, manually). BTW, my own experience with using optionsets is not exactly extensive, either. I've only created a single real optionset myself so far (Data-Sort data; if you are mostly interested in the xml-side of things, there are some more examples in under_development.pluginmap, though: Analysis-Optionset test).

[rkward-devel] Plugin development: New JS-functions getString()/getBoolean()/getList()
Hi! I just wanted to let you know about three new functions for use in plugins' JS code (both code generation and gui scripting). These are replacements for the old getValue()-call. Don't worry: getValue() is not going away. But for new plugins, or when reworking existing plugins, you should use these, instead. - First things first: What's wrong with getValue()? Not much. But this does have a certain peculiarity: getValue() will always return the value as a string, *except* when the value to get is 0, it will return numeric 0, instead of a string(*). This was a hack to keep plugins working after the conversion from PHP(*) However, this can cause problems in a corner case: In a free-field input, the user might want to enter 0. This can cause the plugin to bail out with an error, if it tries to use string methods on the value (e.g. replace()). - getString() and getBoolean() getString() is almost identical to getValue(), and in fact it is the function you will use most often. The only difference is that it will always return a string, even if that is 0. For use in if()-switches or other logic, there is now a new function getBoolean(). This will try hard to convert the value in question to a logical, even handling the strings true and false. Of course getBoolean() can't do magic, but in contrast to getValue(), if getBoolean() cannot meaningfully convert a value to a logical, it will produce a warning. Speaking of which: There is a new tool window to view RKWard internal debug messages. Activate it from the Windows-menu, or by right- clicking on one of the tool docks. Use it to check your plugins for problems! - getList() getList() is an entirely new function, which will return an Array of strings (if possible). There are only a few use-cases of this, so far. The first is getting a list of objects from varslots with multi=true. Another is the fetching columns from the new matrix-element, that is new in the development version. A third is the new optionset-element, which I will write about, soon. The advantages of getList() over using getValue() (or getString()), and then splitting by newlines, should be obvious. Backwards compatibility note: getString() was added in RKWard 0.6.0, already. getBoolean() and getList() are available in the development version, only. Regards Thomas (*): In PHP, if (0) echo (yes); will not generate anything (0 evaluates to false). In JS, if (0) echo (yes); will generate yes (0 evaluates to true). Returning 0 as a numeric value kept plugins working after the conversion from PHP. And in most - but not all - cases, JS is smart enough to convert the numeric representation back to a string, if needed. signature.asc Description: This is a digitally signed message part. -- LogMeIn Rescue: Anywhere, Anytime Remote support for IT.
