2022-03-23Make project configuration variables non-nullable by defaultBoris Kolpackov1-4/+46
A project configuration variable with the NULL default value is naturally assumed nullable, for example: config [string] config.libhello.fallback_name ?= [null] Otherwise, to make a project configuration nullable we use the `null` variable attribute, for example: config [string, null] config.libhello.fallback_name ?= "World"
2022-03-23Clarify config::save_*_omitted semanticsBoris Kolpackov1-5/+12
2022-03-22Add ability to disfigure specific configuration variablesBoris Kolpackov1-0/+27
The new config.config.disfigure variable can be used to specify the list of variables to ignore when loading config.build (and any files specified in config.config.load), letting them to take on the default values. For example: $ b configure config.config.disfigure=config.hello.fancy

2022-03-10Remove update variable from source of synthesized dependencyBoris Kolpackov1-1/+14
2022-03-09Rename execute_wait() to execute()Boris Kolpackov3-26/+23
The old half-way semantics of execute() wasn't useful.

2022-03-08Update C/C++ headers and ad hoc sources during match by defaultBoris Kolpackov1-19/+50
Essentially, all headers as well as ad hoc headers and sources are now treated by the cc::link_rule as if they had update=match unless explicit update=execute is specified.
2022-03-08Add update=execute special value for cases where it's not defaultBoris Kolpackov3-4/+6

2022-03-04Convert stream names to lower case in documentationKaren Arutyunov2-7/+7
2022-03-02Add update operation-specific variable with unmatch|match additional valuesBoris Kolpackov24-148/+395
Note that the unmatch (match but do not update) and match (update during match) values are only supported by certain rules (and potentially only for certain prerequisite types). Additionally: - All operation-specific variables are now checked for false as an override for the prerequisite-specific include value. In particular, this can now be used to disable a prerequisite for update, for example: ./: exe{test}: update = false - The cc::link_rule now supports the update=match value for headers and ad hoc prerequisites. In particular, this can be used to make sure all the library headers are updated before matching any of its (or dependent's) object files.

2022-02-17Add support for cheaply starting parallel scheduler pre-tuned to serialBoris Kolpackov3-15/+43
2022-02-17Add build.mode global variableBoris Kolpackov1-0/+12
This value signals any special mode the build system may be running in. The two core modes are `no-external-modules` (bootstrapping of external modules is disabled) and `normal` (normal build system execution). Build system drivers may invent additional modes (for example, the bpkg `skeleton` mode that is used to evaluate depends clauses).
