2022-05-20Make $config.origin() also available internally as config::origin()Boris Kolpackov1-0/+16
2022-03-23Clarify config::save_*_omitted semanticsBoris Kolpackov1-5/+12
2021-09-20Assign pre-defined semantics to config.<project>.develop variablesBoris Kolpackov1-12/+25
This variable allows a project to distinguish between development and consumption builds. While normally there is no distinction between these two modes, sometimes a project may need to provide additional functionality during development. For example, a source code generator which uses its own generated code in its implementation may need to provide a bootstrap step from the pre-generated code. Normally, such a step is only needed during development. See "Project Configuration" in the manual for details.

2020-04-27Rework tool importation along with cli moduleBoris Kolpackov1-0/+14
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)"
