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] [OPTIONS]

Example1

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.

bash cargo rls-install -n # --nightly

Example2

All operations are done without approval until the end.

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

Example3

Install Stable Rust, RLS and change the default toolchain.

bash cargo rls-install -s # --stable

Example4

Install Beta Rust, RLS and change the default toolchain.

bash cargo rls-install -b # --beta

Example5

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

bash cargo rls-install -ysbn

Example6(v1.0.17-)

Check the build status of Rust and RLS.
This command is intended for use alone.

bash cargo rls-install -v # --view

Example7(v1.0.23-)

Installs the specified component. Use rustup component add command.

```bash

example: rustfmt

cargo rls-install -c rustfmt # --component-add rustfmt ```

Example8(v1.0.25-)

Note: Changes the selected Rust channel to the default toolchain. Use rustup default command. If you specify cargo rls-instrall -d n, Nightly Rust with the most recent date will be specified as the default toolchain.

```bash

Use stable

cargo rls-install -d s

Use beta

cargo rls-install -d b

Use target beta(v1.0.28-)

cargo rls-install -d beta-2019-05-19

Use nightly

cargo rls-install -d nightly

Use latest nightly rust toolchain

cargo rls-install -d n

Use target nightly rust toolchain

cargo rls-install -d nightly-2019-05-21 ```

Example9(v1.0.28-)

Uninstall the selected Rust channel. Use rustup uninstall command.
Note: Latest nightly rust and default toolchain isn't eligible for uninstallation.

```bash

Uninstall stable

cargo rls-install -u s

Uninstall beta

cargo rls-install -u b

Uninstall target beta

cargo rls-install -u beta-2019-05-19

Uninstall nightly

cargo rls-install -u n

Uninstall target nightly

cargo rls-install -u nightly-2019-5-21

Uninstall all but the latest nightly rust dated

cargo rls-install -u a # a or all ```

Example10(v2.0.4-)

Nightly Rust will be installed on the date you choose.

bash cargo rls-install -i nightly-2020-03-19

Example11(v2.0.5-)

Show installed toolchains. Use rustup show command.

bash cargo rls-install show

Example12(v2.0.5-)

Install formatter tools: clippy and rustfmt. Use rustup component add command.

bash cargo rls-install formatter
