2018-11-14Fallback to loading outer buildfile if there isn't one in src_baseBoris Kolpackov1-7/+9
This covers the case where the target is defined in the outer buildfile which is common with non-intrusive project conversions where everything is built from a single root buildfile.
2018-11-09Add support for relative to base scope command line variable overridesBoris Kolpackov1-2/+2
Currently, if we say: $ b dir/ ./foo=bar The scope the foo=bar is set on is relative to CWD, not dir/. While this may seem wrong at first, this is the least surprising behavior when we take into account that there can be multiple dir/'s. Sometimes, however, we do want the override directory to be treated relative to (every) target's base scope that we are building. To support this we are extending the '.' and '..' special directory names (which are still resolved relative to CWD) with '...', which means "relative to the base scope of every target in the buildspec". For example: $ b dir/ .../foo=bar Is equivalent to: $ b dir/ dir/foo=bar And: $ b liba/ libb/ .../tests/foo=bar Is equivalent to: $ b liba/ libb/ liba/tests/foo=bar libb/tests/foo=bar
2018-08-30Handle missing export directive in export stubBoris Kolpackov1-2/+11
If none were executed, then we assume the requested target is not exported.

2018-07-23Sanitize project name when forming config.import.<proj> variableBoris Kolpackov1-5/+23

2018-04-27Add support for build hooksBoris Kolpackov1-43/+135
The following buildfiles are loaded (if present) at appropriate times from the out_root subdirectories of a project: build/bootstrap/pre-*.build # before loading bootstrap.build build/bootstrap/post-*.build # after loading bootstrap.build build/root/pre-*.build # before loading root.build build/root/post-*.build # after loading root.build

2018-01-05Add support for variable aliasesBoris Kolpackov1-1/+1
2018-01-04Load config.build in init(), not boot()Boris Kolpackov1-6/+10
We now make sure the config module is init'ed first.
2017-12-13Implement info meta operationBoris Kolpackov1-7/+25
This meta operation can be used to print basic information (name, version, source/output roots, etc) for one or more projects.
2017-11-29Reimplement module sidebuilding using an ad hoc subprojectBoris Kolpackov1-15/+39
2017-09-06Call dist callback in subprojectsBoris Kolpackov1-1/+0
This fixes a bug with no updating manifest versions in build2-toolchain subprojects.
2017-09-03Cleanup project src/out_root/base discovery logicBoris Kolpackov1-14/+9
Specifically, we no longer support specifying the out_base explicitly and assuming work is src_base.
2017-07-28Restrict exe{} search to PATH when importingBoris Kolpackov1-1/+3
2017-05-13Fix VC15 warnings (/W3)Karen Arutyunov1-1/+1

2017-03-02Implement parallel matchBoris Kolpackov1-3/+3
2017-02-13Track variable value modificationsBoris Kolpackov1-1/+1
2017-02-13Tighten code that operates during both search/match and executeBoris Kolpackov1-17/+29
2017-02-13Pass const scope& where modification should not happenBoris Kolpackov1-17/+19
2017-02-13Implement pattern-based variable typing, tighten variable type updateBoris Kolpackov1-4/+8
2017-02-13Add notion of phase, enforceBoris Kolpackov1-4/+5
2017-02-13Add model mutex, make var_pool const by defaultBoris Kolpackov1-42/+41
2017-01-23Implement automatic loading of directory buildfilesBoris Kolpackov1-3/+46
Now instead of explicitly writing: d = foo/ bar/ ./: $d include $d We can (usually) just write: ./: foo/ bar/
2017-01-19Get rid of extension_poolBoris Kolpackov1-3/+6
2017-01-19Get rid of project_name_poolBoris Kolpackov1-8/+8
With small string optimizations this is most likely a hindrance rather that an optimization.
2017-01-09Make use of operator<<(ostream, exception)Karen Arutyunov1-3/+3
2017-01-05Update copyright yearBoris Kolpackov1-1/+1
2016-12-17Add support for specifying individual paths of imported targetsBoris Kolpackov1-44/+101
The new config.import.* variable format is: config.import.<proj>.<name>[.<type>] For example: b config.import.build2.b=/opt/build2/bin/b b config.import.build2.b.exe=b-boot
2016-12-17Use PATH search as fallback import mechanism for exe{} targetsBoris Kolpackov1-7/+52
2016-11-22Use diagnostics facility from libbutlBoris Kolpackov1-6/+3
2016-11-18Implement noop meta-operationBoris Kolpackov1-0/+1
The effect is loading all the buildfiles but not searching/matching/executing any targets/operations. Useful for testing.

2016-08-22Add few extra tracing statementsBoris Kolpackov1-0/+10
2016-07-30Construct paths to use canonical directory separatorsBoris Kolpackov1-8/+15
Hardcoding separators as in "build/root.build" is now a big no-no.
2016-07-30Actualize project root directoriesBoris Kolpackov1-3/+3
This solves the problem of changing path spelling on platforms with case- insensitive filesystems. For example, you may build a project in the current working directory without specifying any paths. This means the current working directory will be used as the project's root. On Windows this could be C:\x. Now you are building another project that imports the above project and you specify config.import.x variable pointing to the above build. But you are lazy to type capital C so you spell it as config.import.x=c:\x. What happens now is the value from config.import.x is used as the project root. And now it is a different spelling compared to your original build. This is not a problem when the build system itself is concerned -- it is smart enough to use case-insensitive comparison. However, we often use roots to derive other things, say, -I options that we pass to compilers. And these options are normally no longer treated as (case-insensitive) paths. If they are hashed and the result stored in depdb, then we end up with rebuilds that are triggered by changes from C:\ to c:\.
