Filters are extremely capable and can do the equivalent of the logical conditions;
- AND OR NOT and even NAND NOR XOR and XNOR
However they do this within the filter syntax. This means if you are new to TiddlyWiki even AND and OR are not obvious, and only tend to be understood once you gain a deeper understanding of the filter syntax.
- This seems it may present a tiddlywiki adoption barrier.
With the introduction of functions/custom functions and the %if syntax we are empowered to write clearer filter conditions and structures. However the above logical conditions are not well catered for.
The Challenge for you/us, if you choose to accept it, is how can we provide some methods to allow all users, but particularly new users to make use of these logical conditions within filters.
- Essential to this endeavour is coming up with the appropriate description how to do this, although we should be able to make it easier for users.
- Some custom functions, procedures or even widgets are likely to help
- We may find some slight core additions will help close any gaps.
Any ideas?
