AST_Dot and AST_Sub properties are now mangled by --mangle-props without regard to being used in an assignment statement. Note: if --mangle-props is used then all javascript files used must be uglified with the same mangle options. Fix the ignore_quoted=true mangle option, also known as `--mangle-props=unquoted`. If a given property is quoted anywhere it will not be mangled in any quoted or non-quoted context.	2016-08-14 21:51:25 +02:00

kzc	b40d5de69c	Change the default sequences limit to 200 to speed up compress. Has little or no impact on minification size in the majority of cases but can speed up rollup builds significantly. This sequences change also has the beneficial side effect of avoiding "stack size exceeded" errors on very large input files. The user is free to alter the sequences limit if they are so inclined. The previous sequences limit was 2000. 20 is often sufficient.	2016-07-01 09:41:31 +02:00

Anthony Van de Gejuchte	3a7d53f3cf	Move OctalEscapeSequence to read_escape_char This should simplify and improve implementation, make it easier to implement template strings, and keep master a bit more in sync with harmony. Previous implementation wasn't broken, though the loop gave me the impression it could read infinite numbers and annoyed me a bit. It was also slightly unnecessary because the lookup involved only 3 characters.	2016-06-30 21:42:15 +02:00
