It seems to me that it’s mostly a matter of style: I strongly prefer using properties for just that: properties; meaning simple values that you can get and/or set. I use functions (or methods) when actual work is being done. Maybe something has to be computed or read from disk or from a database: In … Read more
We’ve developed a tool that is able to precisely deal with this scenario. Check http://www.semanticmerge.com It merges (and diffs) based on code structure and not using text-based algorithms, which basically allows you to deal with cases like the following, involving strong refactor. It is also able to render both the differences and the merge conflicts … Read more
Both versions are correct. The biggest difference between them is that in the case of <h1><a>..</a></h1> only the text in the title will be clickable. If you put the <a> around the <h1> and the css display property is block (which it is by default) the entire block (the height of the <h1> and 100% … Read more
First off, the facts: if (booleanValue) Will satisfy the if statement for any truthy value of booleanValue including true, any non-zero number, any non-empty string value, any object or array reference, etc… On the other hand: if (booleanValue === true) This will only satisfy the if condition if booleanValue is exactly equal to true. No … Read more
Java restricts the types of expressions that are allowed in so-called “expression statements”. Only meaningful expressions that have potential side effects are allowed. It disallows semantically meaningless statements like 0; or a + b;. They’re simply excluded from the language grammar. A function call like foo() can, and usually does, have side effects, so it … Read more
As of C++14, they often are. C++14 adds a fringe case where parentheses around a return value may alter the semantics. This code snippet shows two functions being declared. The only difference is parentheses around the return value. int var1 = 42; decltype(auto) func1() { return var1; } // return type is int, same as … Read more
You might want to check out this paper: Sentence similarity based on semantic nets and corpus statistics (PDF) I’ve implemented the algorithm described. Our context was very general (effectively any two English sentences) and we found the approach taken was too slow and the results, while promising, not good enough (or likely to be so … Read more
Partial matching exists to save you typing long argument names. The danger with it is that functions may gain additional arguments later on which conflict with your partial match. This means that it is only suitable for interactive use – if you are writing code that will stick around for a long time (to go … Read more
Yes, it’s valid. However, HTML5 encourages to use […] headings of the appropriate rank for the section’s nesting level. But it’s not a requirement, so you are free to choose. Using h1 everywhere allows for moving sections without having to adjust the heading ranks (although it would never be invalid, even if the ranks are … Read more
This a really good question (and also a can of worms) because it gets at the interface of qi and phoenix. I haven’t seen an example either, so I’ll extend the article a little in this direction. As you say, functions for semantic actions can take up to three parameters Matched attribute – covered in … Read more
