Age	Commit message (Collapse)	Author	Files	Lines
2022-12-15	Improve escape sequence support	Boris Kolpackov	1	-23/+73
	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
2022-10-18	Fix unexpected 'unterminated double-quoted sequence' script error	Karen Arutyunov	1	-8/+59

2022-09-29	Tighten low-verbosity diagnostics name deduction logic	Boris Kolpackov	1	-0/+16
	Specifically, don't try to derive low-verbosity name from what looks like an eval context of a function call.
2021-11-23	Fix multi-line comment parsing to accept trailing eos in place of newline	Boris Kolpackov	1	-6/+7

2021-05-28	Add support for regex-based target type/pattern specific variables	Boris Kolpackov	1	-11/+8
	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	-18/+37
	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	-3/+5
	Specifically, they are reserved for future support of arithmetic evaluation contexts and evaluation pipelines, respectively.
2020-06-19	Fix lexer to fail on invalid UTF-8 sequences	Karen Arutyunov	1	-0/+6

2020-06-10	Handle special variable names when spelled as $(<char>) rather than $<char>	Boris Kolpackov	1	-0/+3

2020-06-10	Handle special variable names in base lexer via mode data	Boris Kolpackov	1	-1/+13

2020-06-05	Add ability to specify ad hoc recipe actions	Boris Kolpackov	1	-4/+4
	We are reusing the buildspec syntax for that.
2020-05-27	Add support for value subscript after expansions	Boris Kolpackov	1	-21/+38
	Value subscript is only recognized in evaluation contexts (due to ambiguity with wildcard patterns; consider: $x[123].txt) and should be unseparated from the previous token. For example: x = ($y[1]) x = (($f ? $y : $z)[1]) x = ($identity($y)[$z])
2020-05-27	Initial support for ad hoc recipes (still work in progress)	Boris Kolpackov	1	-15/+157

2020-05-01	Fix outstanding issue with directive vs assignment differentiation	Boris Kolpackov	1	-5/+18
	Specifically, now the following does the right thing: print +foo
2020-03-20	Lexer support for default value assignment (?=)	Boris Kolpackov	1	-6/+17
	Note: not yet supported in the parser.
2020-02-07	Drop copyright notice from source code	Karen Arutyunov	1	-1/+0

2019-11-15	Generalize attributes to be comma-separated with arbitrary values	Boris Kolpackov	1	-8/+22
	Before: x = [string null] After: x = [string, null]
2019-11-14	Tighten up attribute recognition during parsing	Boris Kolpackov	1	-58/+90
	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
2019-09-30	Reserve `:` in `case` pattern expression for future match extraction support	Boris Kolpackov	1	-5/+6

2019-09-30	Add support for custom match/extract functions in switch expression	Boris Kolpackov	1	-5/+29

2019-09-30	Add support for `case` pattern alternatives	Boris Kolpackov	1	-2/+25
	case <pattern>[ \| <pattern>...]
2019-09-30	Pattern matching support (switch): multiple values implementation	Boris Kolpackov	1	-4/+11

2019-07-01	Split build system into library and driver	Boris Kolpackov	1	-0/+720
