A thought struck me as I was writing a piece of JavaScript code that processed some floating point values. What is the decimal point symbol in JavaScript? Is it always .? Or is it culture-specific? And what about .toFixed() and .parseFloat()? If I'm processing a user input, it's likely to include the local culture-specific decimal separ...

Hey I'm looking for an XML parser for C/C++, just a parser which I give a string as an argument and it returns me a parsed document represented by a class/struct.

There are lots of parsers and lexers for scripts (i.e. structured computer languages). But I'm looking for one which can break a (almost) non-structured text document into larger sections e.g. chapters, paragraphs, etc. It's relatively easy for a person to identify them: where the Table of Contents, acknowledgements, or where the main...
I'm using Getopt::Lucid to process CLO and I've run into an interesting and unexpected problem. The following code: push @clo_spec, map { Switch($_) } qw(-c -m -s -p), map { Switch($_) } qw(--help --man --usage --version), map { Switch($_) } qw(--debug --verbose), map { Param($_) } keys ...
My C#-ish toy grammar now has its first reduce-reduce conflicts! I'm so proud of me. It seems all right to me, however (I switched off to a GLR parser for the occasion). The problem is, while I know the %expect directive can shut up Bison about shift/reduce conflicts, I can't find the equivalent for reduce/reduce conflicts. So what shou...

I would like to parse boolean expressions in PHP. As in: A and B or C and (D or F or not G) The terms can be considered simple identifiers. They will have a little structure, but the parser doesn't need to worry about that. It should just recognize the keywords and or not ( ). Everything else is a term. I remember we wrote simple ari...

I'm about to write a parser for a language that's supposed to have strict syntactic rules about naming of types, variables and such. For example all classes must be PascalCase, and all variables/parameter names and other identifiers must be camelCase. For example HTMLParser is not allowed and must be named HtmlParser. Any ideas for a r...
