2022-12-15	Improve escape sequence support	Boris Kolpackov	1	-5/+3
	Specifically: 1. In the double-quoted strings we now only do effective escaping of the special `$("\` characters plus `)` for symmetry. 2. There is now support for "escape sequence expansion" in the form $\X where \X can be any of the C/C++ simple escape sequences (\n, \t, etc) plus \0 (which in C/C++ is an octal escape sequence). For example: info "foo$\n$\tbar$\n$\tbaz" Will print: buildfile:1:1: info: foo bar baz
2021-05-28	Add support for regex-based target type/pattern specific variables	Boris Kolpackov	1	-1/+2
	This is in addition to the already supported path-based target type/pattern specific variables. For example: hxx{}: x = y # path-based hxx{~/./}: x = y # regex-based
2021-05-28	Recognize quoting of first character in token	Boris Kolpackov	1	-7/+18
	Use this to relax the pattern inclusion/exclusion syntax to only require unquoted +/-.
2020-07-13	Reserve backtick (`) and bit-or (\|) in eval context for future use	Boris Kolpackov	1	-0/+1
	Specifically, they are reserved for future support of arithmetic evaluation contexts and evaluation pipelines, respectively.
2020-06-10	Handle special variable names when spelled as $(<char>) rather than $<char>	Boris Kolpackov	1	-0/+1

2020-05-27	Initial support for ad hoc recipes (still work in progress)	Boris Kolpackov	1	-5/+43

2020-03-20	Lexer support for default value assignment (?=)	Boris Kolpackov	1	-0/+1
	Note: not yet supported in the parser.
2020-02-07	Drop copyright notice from source code	Karen Arutyunov	1	-1/+0

2019-11-14	Tighten up attribute recognition during parsing	Boris Kolpackov	1	-2/+7
	Now it should be possible to use `[]` for wildcard patterns, for example: foo = foo.[hit]xx Note that a leading bracket expression will still be recognized as attributes and escaping or quoting it will inhibit pattern matching. To resolve this case we need to specify an empty attribute list: foo = [] [abc]-foo.cxx
2019-11-11	Use path_name for `-` to stdin/stdout translation	Karen Arutyunov	1	-7/+7

2019-09-30	Add support for `case` pattern alternatives	Boris Kolpackov	1	-0/+2
	case <pattern>[ \| <pattern>...]
2019-07-01	Split build system into library and driver	Boris Kolpackov	1	-0/+191
