The usingTerminal method synchronizes the JLine object which can lead to
deadlock if multiple threads call it. When we just to want to read the
attributes of the terminal, but not modify it, there doesn't seem to be
any reason to use a lock.
I was seeing a number of compiler warnings about the type parameter
Scope:
Settings.scala:55:12: type parameter Scope defined in trait Init shadows class Scope defined in package util. You may want to rename your type parameter, or possibly remove it.
I'm not sure why I wasn't seeing these before, but the fix is simple.
Although this is technically in the internal package, it is exposed to
users when they write a custom input task. I do not think that we should
prevent users/plugin authors from writing their own parser
implementations if there is a different library they prefer. By my
count, there are 21 implementations of this interface in sbt, so it's
unlikely that there is much benefit from a pattern matching perspective.
While the AnyLeft and AnyRight types are necessary to make the extension
class work, I don't want to leak the AnyLeft or AnyRight traits into the
public api. It wasn't neceessary to annotate `some`, but it's good
practice to annotate anything public anyway.
This implements a new sbt.color flag that takes always/auto/never/true/false value as a replacement of current sbt.log.format=true/false flag.
When neither flags are set, the default behavior is to enable color when the terminal supports ANSI and it detects an stdout console (as opposed to redirects).

Dotty has its own logic for displaying problems with the proper file
path, position, and caret, but if we store this information in
Problem#message we end up with duplicated information in the output
since Zinc will prepend/append similar things (see
sbt.internal.inc.ProblemStringFormats). So far, we worked around this in
Dotty by using an empty position in the sbt bridge reporter, but this
means that crucial semantic information that could be used by a Build
Server Protocol implementation and other tools is lost. This commit
allows us to avoid by adding an optional `rendered` field to `Problem`:
when this field is set, its value controls what the user sees, otherwise
we fallback to the default behavior (the logic to do this will be added to
Zinc after this PR is merged and a new release of sbt-util is made).
Positions in the Language Server Protocol and Build Server Protocol are
line/column-based instead of offset-based, so this is more convenient.
Computing the line/column from the offset is possible but requires
reading the source file.
A position now has a start, an end, and a point (the existing `offset`),
just like it does in the Scala compiler. This information is especially
useful for displaying squiggly lines in an IDE.
This commit and the next one are required for https://github.com/sbt/zinc/pull/571
Make sure that we generate valid ID (according to matches(ID, s)) so
that we properly test the new validID implementation.
And that's what led to the bug fix. :)
This showed up in profiling. It's known that TypeTags are expensive. Even
more so if the reflect universe is accessed during startup when the
class loading and JIT compiler are busy enough with other stuff.
It turned up in profiling sessions. Previously, it used parser combinators
which are somewhat slow especially when the JVM is still cold.
The grammar for ID is simple enough to afford this handwritten parser.
There are just too many instances in which sbt's code relies on
the `lastModified`/`setLastModified` semantics, so instead of moving
to `get`/`setModifiedTime`, we use new IO calls that offer the new
timestamp precision, but retain the old semantics.
Fixessbt/sbt#1812
This adds unified slash syntax for both sbt shell and the build.sbt DSL.
Instead of the current `<project-id>/config:intask::key`,
this adds `<project-id>/<config-ident>/intask/key` where <config-ident> is the Scala identifier notation for the configurations like `Compile` and `Test`.
This also adds a series of implicits called `SlashSyntax` that adds `/` operators to project refererences, configuration, and keys such that the same syntax works in build.sbt.
These examples work for both from the shell and in build.sbt.
