  • cargo-check: statically check a project, but don’t build a binary.

  • cargo-edit: add or remove dependencies for a project through the
    command line.

  • cargo-graph: build dependency graphs for a project using GraphViz.

  • cargo-watch: automatically re-run a Cargo command when the project
    changes.

@nrc and I have been hard at work on IDE support, turning the Rust
Language Server demo weshowed at RustConf2.2kinto an actual project.
Today, we’re making our firstsource pre-alpha release1.8kof the
project.

notes。

We’re excited about what the RLS project will mean for Rust development
in the future. The RLS aims at being a self-contained, full-featured
application for IDE support. By being self-contained, and following a
simple protocol, all the core IDE functionality will be available to any
editor.

dotnet
run

下载地址: Rust 1.5 stable。

At least… that’s the theory. We still have a lot of work to get there.
We need developers, testers, and people with expertise in various
editors to help flesh out the support and make sure the experience feels
good.

 

Rust 是 Mozilla 的一个新的编程语言,由web语言的领军人物Brendan
Eich(js之父),Dave Herman以及Mozilla公司的Graydon Hoare 合力开发。

****The RLS is not yet ready for primetime** **. This early
release may eat your hard drive or frighten your neighbors. We recommend
only using the RLS with code you are making regular backups of. If you
are still interested, you can get started by following theguide605.

Where we need help

First, we’re looking for people who want to write code and help flesh
out the RLS. There are a growing list ofissues to tackle481as well as
a number of FIXMEs in the code.

If you’re okay with living on the bleeding edge, we’d love to get
testing feedback. Do features stop working in some cases? What were the
steps that caused them to break?File an issue40and let us know.

The RLS uses theLanguage Server Protocol1.1k, a json-rpc protocol
backed by Microsoft and Red Hat. It’s a relatively young protocol.
Currently, Eclipse and Visual Studio Code support this protocol, and it
should be possible to add support to other editors. It just takes
putting in the work.

dotnet new 

        Creates a new project, configuration file, or solution based on
the specified template.

What works

The current version supports the following features:

  • errors as you type
  • 澳门新葡亰网址下载 ,goto def
  • find all refsrenamingtypes/docs/doc links on hover
  • types and docs from the standard library

Description

The dotnet new command provides a convenient way to initialize a valid
.NET Core project.

The command calls the template
engine to create the artifacts on
disk based on the specified template and options.

 

 

What doesn’t work

Of course, not everything is roses. There are also some shortcomings:

  • Analysis can be slow. This is especially true for initial analysis,
    which has to work its way through all your dependencies.
  • Projects with dependencies that have custom build steps or compiler
    plugins aren’t supported out of the box. To support them you need to
    enable the “slow, but more accurate” mode by removing the
    “-Zno-trans” command to the compiler in build.rs.
  • Please use caution when using this. The RLS can make updates
    your code when doing tasks like rename/refactor. Always check that
    the RLS made edits that you expected. If not, file an issue so we
    can follow up.

dotnet restore

       Restores the dependencies and tools of a project.

Next steps

We’re currently working towards an Alpha release, which is geared
towards a broader audience. To get there, we’ve trackingtasks242to
help us reach the Alpha.

If you have any questions you can ping nrc or jntrnr on irc.mozilla.org

Description

The dotnet restore command uses NuGet to restore dependencies as well
as project-specific tools that are specified in the project file. By
default, the restoration of dependencies and tools are performed in
parallel.

 

In order to restore the dependencies, NuGet needs the feeds where the
packages are located.

Feeds are usually provided via the NuGet.config configuration file.

A default configuration file is provided when the CLI tools are
installed.

You specify additional feeds by creating your own NuGet.config file in
the project directory.

You also specify additional feeds per invocation at a command prompt.

 

For dependencies, you specify where the restored packages are placed
during the restore operation using the --packages argument.

If not specified, the default NuGet package cache is used, which is
found in the .nuget/packages directory in the user’s home directory on
all operating systems (for example, /home/user1 on Linux or
C:Usersuser1 on Windows).

 

For project-specific tooling, dotnet restore first restores the
package in which the tool is packed, and then proceeds to restore the
tool’s dependencies as specified in its project file.

 

The behavior of the dotnet restore command is affected by some of the
settings in the Nuget.Config file, if present.

For example, setting the globalPackagesFolder in NuGet.Config places
the restored NuGet packages in the specified folder.

This is an alternative to specifying the --packages option on the
dotnet restore command.

For more information, see the NuGet.Config
reference.

dotnet run

     Runs source code without any explicit compile or launch commands.

Description

The dotnet run command provides a convenient option to run your
application from the source code with one command.

It’s useful for fast iterative development from the command line.

The command depends on the
dotnet build
command to build the code.

Any requirements for the build, such as that the project must be
restored first, apply to dotnet run as well.

 

Output files are written into the default location, which is
bin/<configuration>/<target>.

For example if you have a netcoreapp1.0 application and you run
dotnet run, the output is placed in bin/Debug/netcoreapp1.0.

Files are overwritten as needed.

Temporary files are placed in the obj directory.

 

If the project specifies multiple frameworks, executing dotnet run
results in an error unless the -f|--framework <FRAMEWORK> option is
used to specify the framework.

 

The dotnet run command is used in the context of projects, not built
assemblies. If you’re trying to run a framework-dependent application
DLL instead, you must use
dotnet
without a command. For example, to run myapp.dll, use:

 

dotnet myapp.dll

For more information on the dotnet driver, see the .NET Core Command
Line Tools
(CLI) topic.

 

In order to run the application, the dotnet run command resolves the
dependencies of the application that are outside of the shared runtime
from the NuGet cache. Because it uses cached dependencies, it’s not
recommended to use dotnet run to run applications in production.
Instead, create a
deployment
using the
dotnet publish
command and deploy the published output. 

 

 

dotnet –version
