cargo-rls-install

Purpose

Rust Language Server easy install

Every night, I look for a day when I can use RLS which may be broken.
In order to realize it, this program goes to see the page that mexus's scripts updates everyday, and scrapes it.

If we had no mexus page in the first place, we would have never made Cargo subcommand,
nor did I feel like using Rust.

Installation

bash cargo install cargo-rls-install

Preparing for installation (Linux only)

For Linux, it is necessary to install OpenSSL for installation.

```bash

Ubuntu or Debian

sudo apt install libssl-dev

WSL(Windows Subsystem for Linux)

sudo apt install libssl-dev sudo apt install build-essential sudo apt install pkg-config

RedHut

sudo yum install openssl-devel

RedHut(Fedora etc.)

sudo dnf install openssl ```

Usage

bash cargo rls-install [FLAGS]

Example1

bash cargo rls-install -n # --nightly

Three operations are executed by the above command.

1. Rust Language(Nightly channel) install.
2. RLS(Rust Language Server) install.
3. Change default toolchain.

Before executing each operation, ask whether to execute it.

Example2

bash cargo rls-install -ny # --nightly --yes

All operations are done without approval until the end.

Example3

bash cargo rls-install -s # --stable

Install Stable Rust and RLS and change the default toolchain.

Example4

bash cargo rls-install -b # --beta

Install Beta Rust and RLS and change the default toolchain.

Example5

bash cargo rls-install -ysbn

Install RLS on all Rust channels. The default toolchain is Nightly Rust, as the last operation on Nightly Rust is done.

Example6(v1.0.17-)

bash cargo rls-install -v # --view

Check the build status of Rust and RLS. This command is intended to be used only by itself.

Example7(v1.0.23-)

bash cargo rls-install -f # --rustfmt cargo rls-install -c rustfmt # --comp-add rustfmt

Install component(example: rustfmt). Use rustup component add command.

Example7(v1.0.25-)

```bash

Use stable

cargo rls-install -ds

Use beta

cargo rls-install -db

Use nightly

cargo rls-install -dnightly

Use latest nightly rust toolchain

cargo rls-install -dn

Use target nightly rust toolchain

cargo rls-install -dnightly-2019-05-21 ```

Change default toolchain. Use rustup default command.
