From b236b111e52d08245d9bc1caadd6b78f7723f42c Mon Sep 17 00:00:00 2001 From: Boris Kolpackov Date: Tue, 4 Jan 2022 14:56:56 +0200 Subject: Add depdb-dyndep --update-{include,exclude} options 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. --- libbuild2/build/script/builtin.cli | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) (limited to 'libbuild2/build/script/builtin.cli') diff --git a/libbuild2/build/script/builtin.cli b/libbuild2/build/script/builtin.cli index 938c554..9f3f2ba 100644 --- a/libbuild2/build/script/builtin.cli +++ b/libbuild2/build/script/builtin.cli @@ -20,6 +20,20 @@ namespace build2 // Note that --byproduct, if any, must be the first option and is // handled ad hoc, kind of as a sub-command. // + // Similarly, --update-{include,exclude} are handled ad hoc and must + // be literals, similar to the -- separator.
