- split the Dart CLI tool out of the VM into it's own embedder which runs in AOT mode. The pure Dart VM executable is called 'dartvm' and has no Dart CLI functionality in it - the Dart CLI executable parses the CLI commands and invokes the rest of the AOT tools in the same process, for the 'run' and 'test' commands it execs a process which runs 'dartvm' to run - 'dart hello.dart' execs the 'dartvm' process and runs 'hello.dart' - the Dart CLI is not generated for ia32 as we are not shipping a Dart SDK for ia32 anymore (support to execute the 'dartvm' for ia32 architecture is retained) - the Dart CLI tool is not built in the internal Dart SDK builds TEST=ci Some performance improvement numbers 'dart format pkg/dartdev' goes from 1.17 secs to 0.22 secs 'dart doc pkg/dartdev' goes from 100.2 secs to 66.6 secs 'dart fix pkg/dartdev' goes from 19.3 secs to 14.5 secs Change-Id: I66984a26cb2ab014b34dc1873f1f3d2884e13518 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/364202 Commit-Queue: Ben Konyi <bkonyi@google.com> Reviewed-by: Ben Konyi <bkonyi@google.com>

Start Dart's analysis server.
|
|
|
|
This is a long-running process used to provide language services to IDEs and other tooling clients.
|
|
|
|
It communicates over stdin and stdout and provides services like code completion, errors and warnings, and refactorings. This command is generally not user-facing but consumed by higher level tools.
|
|
|
|
