dotty.tools.dotc.sbt

Utilities to deal with xsbti.api.

Mostly comes from https://github.com/sbt/zinc/blob/c46643f3e68d7d4f270bf318e3f150f5a59c0aab/internal/zinc-apiinfo/src/main/scala/xsbt/api/APIUtil.scala

This phase sends a representation of the API of classes to sbt via callbacks.

This is used by sbt for incremental recompilation.

See the documentation of ExtractAPICollector, ExtractDependencies, ExtractDependenciesCollector and http://www.scala-sbt.org/1.x/docs/Understanding-Recompilation.html for more information on incremental recompilation.

The following flags affect this phase: -Yforce-sbt-phases -Ydump-sbt-inc

This phase sends information on classes' dependencies to sbt via callbacks.

This is used by sbt for incremental recompilation. Briefly, when a file changes sbt will recompile it, if its API has changed (determined by what ExtractAPI sent) then sbt will determine which reverse-dependencies (determined by what ExtractDependencies sent) of the API have to be recompiled depending on what changed.

See the documentation of ExtractDependenciesCollector, ExtractAPI, ExtractAPICollector and http://www.scala-sbt.org/0.13/docs/Understanding-Recompilation.html for more information on how sbt incremental compilation works.
