Update: New blog post about choosing Visual Studio Code for Rust because of better IDE support.
In my first blog post I was starting out with Atom editor but quickly realized that it is lacking features of Integrated Development Environments (IDEs). I need to be able to click on functions and data types to jump to their definitions and was not able to get that working in Atom.
Installing Java to run Eclipse
sudo apt install openjdk-8-jre
In my first installation attempt Eclipse had problems to connect to external Github software sources sites because of missing Java SSL root certificates. After filing an issue in the wrong place I found the following fix for missing Java SSL certificates:
sudo dpkg --purge --force-depends ca-certificates-java sudo apt-get install ca-certificates-java
Installing Eclipse base
The Eclipse downloads page gives you an installer where you select additional packages for whatever platform you want to develop on. You can skip all of that because we will install the external Rust extension later, so we select "Eclipse Platform (Neon)".
On the "Projects" step of the installer I only selected EGit for Git support in
Eclipse which I always need. As installation folder I picked "eclipse" which
means Eclipse will end up in your home directory for example at
/home/klausi/eclipse. When you finish the installation you will have to
accept some license agreements and trust some certificates.
In the end Eclipse should start up successfully.
Adding a launcher shortcut
Create a new file at
content like this:
[Desktop Entry] Name=Eclipse Type=Application Exec=/home/klausi/eclipse/eclipse/eclipse Terminal=false Icon=/home/klausi/eclipse/eclipse/icon.xpm Comment=Integrated Development Environment NoDisplay=false Categories=Development;IDE; Name[en]=Eclipse
Installing RustDT on Ubuntu
Make sure you have a Rust toolchain environment set up:
curl https://sh.rustup.rs -sSf | sh
(the usual security warning: make sure to trust your sources before you execute random scripts from the internet.)
source $HOME/.cargo/env cargo install racer cargo install rustfmt cargo install --git https://github.com/RustDT/Rainicorn --tag version_1.x rustup component add rust-src
Now we need the RustDT Eclipse plugin from rustdt.github.io. Follow the installation and configuration instructions there closely.
My settings in Window -> Preferences -> Rust:
- Rust installation directory:
- Rust "src" directory:
I'm also using the option "Format automatically on editor save". No questions anymore what the correct code style is :-)
The installation of Eclipse is a bit tedious and RustDT takes a bit of configuration, but I think it is totally worth it to be more productive when writing Rust. Eclipse works better for me than Atom Editor. I also filed a pull request to update the available Eclipse features on areweideyet.com.
