Also fix bug in out clearing.

2022-10-10Preparatory work for public/private variable distinctionBoris Kolpackov1-1/+1
We still always use the public var_pool from context but where required, all access now goes through scope::var_pool().

2021-06-08Implement ad hoc regex pattern rule supportBoris Kolpackov1-17/+33
An ad hoc pattern rule consists of a pattern that mimics a dependency declaration followed by one or more recipes. For example: exe{~'/(.*)/'}: cxx{~'/\1/'} {{ $cxx.path -o $path($>) $path($<[0]) }} If a pattern matches a dependency declaration of a target, then the recipe is used to perform the corresponding operation on this target. For example, the following dependency declaration matches the above pattern which means the rule's recipe will be used to update this target: exe{hello}: cxx{hello} While the following declarations do not match the above pattern: exe{hello}: c{hello} # Type mismatch. exe{hello}: cxx{howdy} # Name mismatch. On the left hand side of `:` in the pattern we can have a single target or an ad hoc target group. The single target or the first (primary) ad hoc group member must be a regex pattern (~). The rest of the ad hoc group members can be patterns or substitutions (^). For example: <exe{~'/(.*)/'} file{^'/\1.map/'}>: cxx{~'/\1/'} {{ $cxx.path -o $path($>[0]) "-Wl,-Map=$path($>[1])" $path($<[0]) }} On the left hand side of `:` in the pattern we have prerequisites which can be patterns, substitutions, or non-patterns. For example: <exe{~'/(.*)/'} file{^'/\1.map/'}>: cxx{~'/\1/'} hxx{^'/\1/'} hxx{common} {{ $cxx.path -o $path($>[0]) "-Wl,-Map=$path($>[1])" $path($<[0]) }} Substitutions on the left hand side of `:` and substitutions and non-patterns on the right hand side are added to the dependency declaration. For example, given the above rule and dependency declaration, the effective dependency is going to be: <exe{hello} file{hello.map>: cxx{hello} hxx{hello} hxx{common}
2021-05-28Add support for regex-based target type/pattern specific variablesBoris Kolpackov1-4/+4
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

2020-04-27Rework tool importation along with cli moduleBoris Kolpackov1-9/+43
Specifically, now config.<tool> (like config.cli) is handled by the import machinery (it is like a shorter alias for config.import.<tool>.<tool>.exe that we already had). And the cli module now uses that instead of custom logic. This also adds support for uniform tool metadata extraction that is handled by the import machinery. As a result, a tool that follows the "build2 way" can be imported with metadata by the buildfile and/or corresponding module without any tool-specific code or brittleness associated with parsing --version or similar outputs. See the cli tool/module for details. Finally, two new flavors of the import directive are now supported: import! triggers immediate importation skipping any rule-specific logic while import? is optional import (analogous to using?). Note that optional import is always immediate. There is also the import-specific metadata attribute which can be specified for these two import flavors in order to trigger metadata importation. For example: import? [metadata] cli = cli%exe{cli} if ($cli != [null]) info "cli version $($cli:cli.version)"

2020-03-17Rename all find*(variable) to lookup*(variable)Boris Kolpackov1-29/+29
Now we consistently use term "lookup" for variable value lookup. At some point we should also rename type lookup to binding and get rid of all the lookup_type aliases.
