An Optional flag on buildDef is not very useful on its own,
BuildParams is what is exposed to modules.

Build definitions can now specify Optional. If Optional is not
specified the build definition will be followed by a default definition
for all outputs.

This adds (to the ModuleContext) a facility to check if a property is
defined in a module in a Blueprints file.

This change makes the bootstrapping process remove any files that were
previously created by invoking a Ninja rule (i.e. they appear in the .ninja_log
file) but are no longer a build output target.

Add a dependency on the golang tool for each tool output file. This
will allow updating the go version without cleaning the output
directory.

Building cgofilter from main.ninja creates a circular dependency.
Move it to be built by the bootstrap stage instead, where go
files are built without cgofilter.

Regenerating build.ninja.in was non-deterministic, sort the maps
of name, value pairs before writing them.

This change replaces the automatic caller package divination with a
PackageContext object that must be explicitly passed in by callers.

This change adds the DynamicDependerModule interface. Any Module type that
implements that interface will be called before Blueprint does its depenedency
analysis to allow the module to add additional dependencies.

This change eliminates blueprint.ModuleType and replaces it with simple factory
functions. Rather than using the explicitly provided ModuleType names to
essentially identify the Go factory function in the generated Ninja files, we
now use the actual factory function name.

The default target selector uses the name of the host OS.
Modules can implement their own target selector by implementing
the context.TargetSelector interface and its unique selectTarget()
method.
Targets are defined this way in Blueprint files:
cc_library {
name: "libmylib",
deps: ["libmath", "libutils"],
zones: ["frontend"],
srcs: ["main.cpp"],
targets: {
darwin: {
moduleCflags: "-framework OpenGL -framework GLUT",
},
linux: {
deps: ["libx11headers", "libglu"],
},
},
}
In this example, a set of C flags are defined on OS X only and on
Linux, two new dependencies are added.
When a target is selected, its properties are merged with the properties
of the modules:
- a list is appended to the original list (see deps above)
- a string is concatenated to the original string
- a bool replaces the original bool
- a map adds or replaces the key/value pairs of the original map

This change causes Blueprint to stop calling GenerateBuildActions on modules
when one such call results in errors being generated. If a module has failed
for some reason and another module depends on it, then processing the dependee
could end up trying to use the failed module, which may be in an invalid state.

This change makes the ModuleContext and SingletonContext methods respect the
caller's Go package when performing name lookups. It does this by re-parenting
the module or singleton's scope to the scope of the caller's package, thus
allowing a Module or Singleton to pass its context to a function defined in
another Go package and have the called function access variables and rules
defined in its own Go package.

- Make module 'new' functions return slices of properties structs rather than
just one.
- Fix a couple places where errors were being reported incorrectly.
- Add ModuleContext methods for dealing with other modules.
- Make property value unpacking skip unexported struct fields rather than
panicing.

This change adds two new kinds of checks to params validation. First, all
BuildParams must have one or more outputs. Second, any Pool or Rule referenced
must be visible within the Blueprint scope of the caller (e.g. if it's defined
in another Go package then an Import call must have been made). If either of
these conditions are violated it will result in a panic.

This change makes the bootstrap script take two optional flag-based command
line arguments rather than using positional arguments. The -i argument
replaces the old positional arguments (one of which was simply not needed), and
the -r flag now causes the script to regenerate the bootstrap Ninja file for
use when working on Blueprint itself.
Additionally this change allows all the configuration variables used in the
script to be overridden by environment variables. This makes it possible to
create a very simple bootstrap script for a customized Blueprint-based build
system by invoking this script after setting up the proper environment
variables.

This change adds docs to all the blueprint package APIs except for the Module
and Singleton types and their corresponding context types.

This change removes the definition of the Config type in the blueprint package.
The type was simply an empty interface, and it seems more clear to just have
that be explicit in the APIs.

This change adds a bunch of docs describing the bootstrap process. It also
renames a couple things in the source to better correspond with the terminology
used in the docs. On top of that it makes the standalone build to copy minibp
from the .bootstrap/bin directory to the bin directory to make it easier to
find.

This change causes the module and singleton content in generated Ninja files to
be sorted by name.

VariableConfigMethod creates a Ninja variable whose value comes directly from a
method on the config object.
