Quoted strings, in Delphi, use single quotes. Almost always.
But did you know that the Delphi compiler supports double-quoted strings, too?
I didn’t either, until I wrote a Delphi lexer. I set it loose on all of the library source that ships with Delphi, and it complained about this
" character that it didn’t understand. In SysUtils.pas, as it turns out, there’s a line that looks like this:
Yep. Inside an
asm block, you can have a double-quoted character literal. And since I use the same lexer for all source files (i.e., I don’t have a separate lexer for
asm blocks), I too have to support double-quoted strings.
But I only support double quotes around a single apostrophe:
"'". After all, I don’t want to encourage this sort of thing.
