They solve a simpler and more constrained problem which makes it easier to make tools. Something like Windows Forms are basically WYSIWYG - you drop some controls on a canvas and now you have a GUI. But the GUI will not gracefully adapt to

Is that fair? Since we have no pre-Christian sources to compare to, it is hard to say how fairly Snorri represent the tradition. (Obviously the bit where he explains the Norse gods as descendants of princes of Troy is of dubious authenticit

Lots of programming wars is just tribalism. Java is disliked on HN because it represent "enterprise" - big long-lived organizations which maintain a codebase for decades and therefore conservative. A different tribe than the start

Here he is talking about humility in the act of writing code, by recognizing the limits of the minds capacity and therefore keeping the code simple to understand rather than clever. He wasn't particularly humble in his writings.

StackOverflow has its share of problems, including overzealous moderation. I do civic duty by often voting for reopen and moderating the reopen queue. That said, removing moderation is not the solution. If you look at the unmoderated new qu

Yeah the trailing slash in <br /> is legal in HTML, but it doesn't actually make the tag self-closing. For example <b /> is still an opening tag which require a </b>.

OK but these are two separate question. Of course you should use an existing library if it solves the exact problem you have. Don't waste time re-implementing the wheel unless you are doing if for educational purposes. Whether such a l

The content model of the script element is gnarly for historical reasons, but it does not depend on the syntax of the scripting language used: https://html.spec.whatwg.org/multipage/scripting.html#restri...

It is worth noting that back then songwriter and performer were basically separate jobs, and it was very common for multiple artists to record the same song, sometimes even at the same time and competing on the charts. Hound Dog is written

But the question is specifically about that edge case! So how to handle it, if the "robust battle-tested parser" is of no help?

It seems like a solution in search of a problem? How often do you need to embed a spreadsheet in word-processing document? Furthermore, making components from multiple independent vendors interact seamlessly is just an incredibly complex

Correct me if I'm wrong, but I believe HTML tags can still be lexed with a regular expression. The syntax of the script element is cryptic, but it does not contain any recursive productions, so it should still be possible to lex correc

Are you arguing that the effort required to make a regex robust and correct is larger than the effort required to make some hand-rolled character-by-character based lexer robust and correct? Because that sounds counter-intuitive to me. A

As far as I can tell, a SAX parser does not expose the distinction between an opening tag and a self-closing tag. The tag `<foo />` would just emit a startElement event followed by an endElement, exactly the same as `<foo>&

Regular expressions can be as robust as you need them to be, just like any other kind of code. They are a DSL to create lexers, and they are exactly as robust (or hacky) as if you wrote the same lexer by hand.

by goto11 5y ago
The point is that a parser could very well use regexes under the hood to perform the tokenization. Because it is the right tool for the job. A language without regex-support might use something like lex to compile a lexer. Of course you

What I like about regexes is they are typically both the most readable and the best performing solution to the kind of problems they are suited for. Just don't use them for validating email addresses or determining if a number is a p

Handling invalid syntax is another can of worms! It would make all parts of the tokenizer much more complex, not just comments. In the case of XHTML, a parser is supposed to reject any document which is not well formed. HTML parsers typical

The problem is the answers saying "this is not possible". The OP asks a perfectly reasonable question. The answers assume the OP actually meant to ask a different question, and they they ridicule the OP for this imagined questio
