2022-01-10Consider implied targets when resolving dynamic dependenciesBoris Kolpackov2-7/+21
2022-01-06Add depdb-dyndep --update-{include,exclude} optionsBoris Kolpackov10-180/+504
These options specify prerequisite targets/patterns to include/exclude (from the static prerequisite set) for update during match as part of dynamic dependency extraction (those excluded will be updated during execute). For example: depdb dyndep ... --update-exclude libue{hello-meta} ... depdb dyndep ... --update-exclude libue{*} ... depdb dyndep ... --update-include $moc --update-include hxx{*} ... The order in which these options are specified is significant with the first target/pattern that matches determining the result. If only the --update-include options are specified, then only the explicitly included prerequisites will be updated. Otherwise, all prerequisites that are not explicitly excluded will be updated. If none of these options is specified, then all the static prerequisites are updated during match. Note also that these options do not apply to ad hoc prerequisites which are always updated during match.

2021-12-16Don't consider implied existing targets in dyndep logicBoris Kolpackov2-9/+39
While considering implied targets should be harmless, the result is racy.

2021-12-02Automatically register pattern rules for dist meta-operationBoris Kolpackov2-4/+33
We need to do this in order to inject additional pattern prerequisites which may "pull" additional sources into the distribution.

2021-11-30Add support for dynamic dependencies as byproduct of script bodyBoris Kolpackov13-327/+1136
Specifically, the `depdb dyndep` builtin now has the --byproduct option (which must come first). In this mode only the --file input is supported. For example: obje{hello.o}: cxx{hello} {{ o = $path($>) t = $(o).t depdb dyndep --byproduct --what=header --default-type=h --file $t diag c++ ($<[0]) $cxx.path $cxx.poptions $cc.poptions $cc.coptions $cxx.coptions $cxx.mode -o $o -MD -MF $t -c $path($<[0]) }} Naturally, this mode does not support dynamic auto-generated prerequisites. If present, such prerequisites must be specified statically in the buildfile. Note also that the --default-prereq-type option has been rename to --default-type.

2021-11-24Allow calling cc module functions during matchBoris Kolpackov1-2/+8
An ad hoc recipe with dynamic dependency extraction (depdb-dyndep) executes its depdb preamble during match (but after matching all the prerequisites).

2021-11-23Add support for dynamic dependencies in ad hoc Buildscript recipesBoris Kolpackov29-1263/+4718
Specifically, add the new `depdb dyndep` builtin that can be used to extract dynamic dependencies from a program run or a file. For example: obje{hello.o}: cxx{hello} {{ s = $path($<[0]) depdb dyndep $cxx.poptions $cc.poptions --what=header --default-prereq-type=h -- $cxx.path $cxx.poptions $cc.poptions $cxx.mode -M -MG $s diag c++ ($<[0]) o = $path($>) $cxx.path $cxx.poptions $cc.poptions $cc.coptions $cxx.coptions $cxx.mode -o $o -c $s }} Currently only the `make` dependency format is supported.

While we normally don't bother, these specific cases cause failures in the ad hoc C++ recipe tests.

Available overloads: $sort(<names> [, <flags>]) $sort(<ints> [, <flags>]) $sort(<strings> [, <flags>]) $sort(<paths> [, <flags>]) $sort(<dir_paths> [, <flags>]) The following flag is supported by the all overloads: dedup - in addition to sorting also remove duplicates Additionally, the strings overload also support the following flag: icase - sort ignoring case Note that on case-insensitive filesystem the paths and dir_paths overload's order is case-insensitive.
