Looks like the reason that util-cache depended on util-collection was to
define the sjson-new formats (HListFormats) for util-collection's HList.
Given that util-collection already depends on sjsonnew, HListFormats can
also be defined in util-collection.
All that was left then was (a) HListFormatSpec requires
sjsonnewScalaJson, so that was added in test scope, and (b) HListFormats
had to be dropped from sbt.util.CacheImplicits - HListFormats will have
to be imported and/or mixed-in where required downstream. For importing
convenience I defined a companion object.
Simply
import OptJsonWriter.OptOut._
And you'll get the implicit lift, but not the implicit fallback.
You get an ambiguous compile error like this:
[error] /d/sbt-util/internal/util-collection/src/main/scala/sbt/util/OptJsonWriter.scala:28: ambiguous implicit values:
[error] both method conflictingFallback1 in trait OptOut0 of type [A]=> sbt.util.NoJsonWriter[A]
[error] and method conflictingFallback2 in trait OptOut0 of type [A]=> sbt.util.NoJsonWriter[A]
[error] match expected type sbt.util.OptJsonWriter[Foo]
[error] val x = implicitly[OptJsonWriter[Foo]]
[error] ^
Uses TypeTag to recover the full name of type parameter, which is calculated by StringTypeTag. This is sent along in ObjectEvent.
On the other end, we can lookup typeclass instances using the tag key.
* Fixes [sbt/sbt#2781]
* When using `<TAB>` completion the failed errors were always
computed for mathcing projects even if there was no failure,
leading to excessive computation of Levenshtein distances
and a large lag (seconds) on builds with many matching
projects.
sbt's shell provided completion only for keys that were relative to a
defined project, but didn't provide completion for keys that belong to
the build definition only.
This commit fixes this issue by defining a new kind of `Parser` (from
which completions are generated) which runs its input simultaneously on
distinct parsers. We now define a parser for project-level keys and
another parser for build-level keys. These two parsers are eventually
combined, and we get the completions of both parsers.
