[tw] Re: TW equivalents of some simple expressions in common programming langauges

I just wanted to add -- as a non-programmer -- that conceptions of TiddlyWiki "programming language" is grasped best by understanding FUNCTIONAL AIMS. In one way you could say its "programming" is a mess. But IS it programming? 1 - Its unusual, in my limited understanding, for being able to

TiddlyWiki isn't supposed to be a programming language. You may be able to extend it so that it can be used as one, but it is a mark-up language that has some advanced templating and macro features. That is very similar to a programming language and I have absolutely on interest in getting into

Re: [tw] Re: TW equivalents of some simple expressions in common programming langauges

Hi Joe, At the surface, the widget-oriented language of TiddlyWiki is just another domain specific language ( https://en.wikipedia.org/wiki/Domain-specific_language) that we have to learn by doing, little by little. SQL or LaTeX are not of the generic kind either, but they are quite adapted to

I should explain my question a little more. What I wanted to in pseudo code was something like this: If (this_tiddler_has_tag("foo")) { Hello I'm a foo Click } else { Hello } Now there are 10 quadzilion template languages that can do this. For example in django I might write {% if

Also If a variable is set to another variable such as <> the value is not frozen as the value at the time you set it, but will return the name of the current tiddler in the context it is used. You can apparently use wikify to freeze the variable. Others can say this better. Tony -- You

I will add here if the filter read A b b c You would get A b c Or A b c A You would get A b c Because as I conceptualise it the "titles" are deduplicated, because titles are unique. Why because if we had a filter that included taga or tagb We would not want the same tiddler title listed

[tw] Re: TW equivalents of some simple expressions in common programming langauges

Wikitext isn't a Turing completely language, there aren't necessarily equivalents to what you are talking about. TiddlyWiki has very few attributes of a normal programming language, I don't think that tiddlywiki has the equivalent of a procedure from an imperative programming language. You can
