From 09dd2097b77bf3dda4c5eb1ee6eb2a60f05bbec8 Mon Sep 17 00:00:00 2001 From: Haru Date: Sun, 15 Sep 2013 20:24:41 +0200 Subject: Added support for automatic concatenation of adjacent string literals - [ This commit is part of a larger script engine related update ] - Adjacent string literals are now automatically concatenated into one string upon parsing. - Adjacent string literals are string literals (i.e. "such as this", with only whitespace (including line breaks and/or comments) between them. For example, the lines: mes "this will be concatenated " /* skipping this comment */ " into one string"; // at parse time will produce an output of "this will be concatenated into one string". - The feature brings parity with other languages (i.e. C), and makes it easier to split long strings in multiple lines, without having to resort to a, slower, run-time string concatenation operator ('+') - Special thanks to Trojal for the idea.
