2022-05-19Add config.config.unload variable to omit loading config.buildBoris Kolpackov1-7/+34
Note that the configuration is still loaded from config.config.load if specified. Note also that similar to config.config.load, only values specified on this project's root scope and global scope are considered.

2022-05-17Handle stack size querying on OpenBSDBoris Kolpackov1-1/+13
2022-05-11Add $config.origin() functionBoris Kolpackov1-0/+70
This function can be used to query the origin of a configuration variable value. The result is one of `undefined`, `default`, `buildfile`, or `override`.
2022-05-10Use our own implementation of C++14 threads on MinGWBoris Kolpackov3-27/+49
2022-05-06Minor terminology fix in diagnostics and commentsBoris Kolpackov6-8/+8
2022-05-06Minor terminology fix in documentationBoris Kolpackov1-2/+2
2022-05-05Recognize -pthread as king of -l in *.libsBoris Kolpackov4-38/+56
2022-05-05Allow linking libraries without any sources/headers with hintBoris Kolpackov1-3/+8
This can be useful for creating "metadata libraries".

2022-04-24Omit ignorable change detection for header unitsBoris Kolpackov1-1/+9
Since the checksum ignores preprocessor directives, this may cause us to ignore a change to an exported macro.

2022-04-19Use target recipe for auxiliary data storage during match-applyBoris Kolpackov19-147/+288
In particular, we now have separate auxiliary data storage for inner and outer operations.

2022-04-15Omit unnecessary clearing of cached base_scope valuesBoris Kolpackov3-2/+13
2022-04-15Get rid of target::dynamic_type() virtual functionBoris Kolpackov10-132/+301
Instead of overriding this function, derived targets must now set the dynamic_type variable to their static_type in their constructor body.
2022-04-14Add header cache to cc::compile_rule::enter_header()Boris Kolpackov6-35/+202
2022-04-13Fix bug in previous commitBoris Kolpackov1-1/+1

2022-04-08Add hint-less rule match pass for non-perform meta-operations as fallbackBoris Kolpackov1-116/+143
2022-04-07Rename {match,execute}() to *_sync(), add *_complete()Boris Kolpackov14-138/+161
In particular, the match() rename makes sure it doesn't clash with rule::match() which, after removal of the hint argument in simple_rule, has exactly the same signature, thus making it error-prone to calling recursively.
2022-04-06Get rid of stray trailing commasBoris Kolpackov1-6/+6
2022-04-06Work around Clang warningsBoris Kolpackov1-0/+4
2022-04-06Add support for specifying custom ad hoc pattern rule namesBoris Kolpackov2-7/+61
Besides diagnostics, this allows us to use name in the rule hint, for example: [rule_name=hello.link] exe{~'/(.*)/'}: obje{~'/\1/'} {{ $cxx.path -o $path($>) $path($<[0]) }} [rule_hint=hello] exe{hello}: obje{hello} obje{hello}: c{hello-c}
2022-04-06Add support for rule hintsBoris Kolpackov58-253/+648
A rule hint is a target attribute, for example: [rule_hint=cxx] exe{hello}: c{hello} Rule hints can be used to resolve ambiguity when multiple rules match the same target as well as to override an unambiguous match.
2022-03-31Use own type information instead of dynamic_cast in target::is_a()Boris Kolpackov3-24/+35
