graphical-programming

I have a pipe that filters an RSS feed and removes any item that contains "stopwords" that I've chosen. Currently I've manually created a filter for each stopword in the pipe editor, but the more logical way is to read these from a file. I've figured out how to read the stopwords out of the text file, but how do I apply the filter operator to the feed, once for every stopword? The documentation states explicitly that operators can't be applied within the loop construct, but hopefully I'm missing something here. You're not missing anything - the filter operator can't go in a loop. Your best bet

I'm considering building a visual programming language , akin to Scratch , for use by children (a.k.a. poor typists) in programming micro-controllers or robots. There is, for example, a project to build a graphical programming environment for the Arduino . I really like Scratch, and would like the graphical coding to be similar. Scratches source is available under its own free license. It is written in Squeak (based on Smalltalk), and I don't know the language. It occurs to me there might be other projects to build off of. When I looked through Wikipedia's list of graphical languages, I didn't

I am considering the possibility of designing an application that would allow people to develop C++ code graphically. I was amazed when I discovered Scratch (see site and tutorial videos ). I believe most of C++ can be represented graphically, with the exceptions of preprocessor instructions and possibly function pointers. What C++ features do you think could be (or not be) represented by graphical items? What would be the pros and cons of such an application ? How much simpler would it be than "plain" C++? RECAP and MORE: Pros: intuitive simple for small applications helps avoid typos Cons:

I need the tool for graphical representing of work flow in a program (like electronic circuits are described with graphical representation). The representation has to be like the following: functions are boxes and arrows between boxes are "messages". Like this: alt text http://img372.imageshack.us/img372/8471/functionsqv0.png This picture shows the following: (c (a) (b)) Where parameters of c() are named as d and e. On C it would be void c( someType1 d, someType2 e ); someType1 a( void ); someType2 b( void ); .... c( a(), b() ); So I think that I need the tool for manipulation and visual
