From 76be0a35f6c37cda7ba65530330f1ac246fb52a8 Mon Sep 17 00:00:00 2001 From: Boris Kolpackov Date: Wed, 6 Apr 2022 11:26:52 +0200 Subject: Add support for rule hints 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. --- libbuild2/bash/init.cxx | 10 +++++----- libbuild2/bash/rule.cxx | 7 ++++--- libbuild2/bash/rule.hxx | 7 ++++--- libbuild2/bash/target.cxx | 2 +- 4 files changed, 14 insertions(+), 12 deletions(-) (limited to 'libbuild2/bash') diff --git a/libbuild2/bash/init.cxx b/libbuild2/bash/init.cxx index a1effa1..88c88ba 100644 --- a/libbuild2/bash/init.cxx +++ b/libbuild2/bash/init.cxx @@ -20,7 +20,7 @@ namespace build2 namespace bash { static const in_rule in_rule_; - static const install_rule install_rule_ (in_rule_); + static const install_rule install_rule_ (in_rule_, "bash.in"); bool init (scope& rs, @@ -71,11 +71,11 @@ namespace build2 if (install_loaded) { - bs.insert_rule (perform_install_id, "bash.install", install_rule_); - bs.insert_rule (perform_uninstall_id, "bash.uninstall", install_rule_); + bs.insert_rule (perform_install_id, "bash.install", install_rule_); + bs.insert_rule (perform_uninstall_id, "bash.install", install_rule_); - bs.insert_rule (perform_install_id, "bash.install", install_rule_); - bs.insert_rule (perform_uninstall_id, "bash.uninstall", install_rule_); + bs.insert_rule (perform_install_id, "bash.install", install_rule_); + bs.insert_rule (perform_uninstall_id, "bash.install", install_rule_); } return true; diff --git a/libbuild2/bash/rule.cxx b/libbuild2/bash/rule.cxx index ec24226..3048d3c 100644 --- a/libbuild2/bash/rule.cxx +++ b/libbuild2/bash/rule.cxx @@ -41,7 +41,7 @@ namespace build2 // in_rule // bool in_rule:: - match (action a, target& t, const string&) const + match (action a, target& t) const { tracer trace ("bash::in_rule::match"); @@ -424,12 +424,13 @@ namespace build2 // install_rule // bool install_rule:: - match (action a, target& t, const string& hint) const + match (action a, target& t) const { // We only want to handle installation if we are also the ones building // this target.
