Arguments
| :: HasEnvConfig env | |
| => LoadedSnapshot | |
| -> BaseConfigOpts | |
| -> [LocalPackage] | |
| -> Set PackageName | additional packages that must be built |
| -> [DumpPackage () () ()] | locally registered |
| -> (PackageLocationIndex FilePath -> Map FlagName Bool -> [Text] -> RIO EnvConfig Package) | load upstream package |
| -> SourceMap | |
| -> InstalledMap | |
| -> Bool | |
| -> RIO env Plan |
Computes a build plan. This means figuring out which build Tasks
to take, and the interdependencies among the build Tasks. In
particular:
1) It determines which packages need to be built, based on the
transitive deps of the current targets. For local packages, this is
indicated by the lpWanted boolean. For extra packages to build,
this comes from the extraToBuild0 argument of type Set
PackageName. These are usually packages that have been specified on
the commandline.
2) It will only rebuild an upstream package if it isn't present in
the InstalledMap, or if some of its dependencies have changed.
3) It will only rebuild a local package if its files are dirty or some of its dependencies have changed.
