RubyMine: Using pinned tabs will increase your productivity

I highly recommend that you make use of RubyMine's feature to pin tabs.

When you pin all "important" files, you can follow method definitions, wildly open files from search results and have a ton of open tabs – without the problem of finding the stuff you were working on before.

Guide

  1. Pin the tabs of files that are currently in the focus of your work (important models, specs, etc):
    • Right-click a tab and select "Pin tab"
    • Or use a shortcut (see below)
  2. Work as usual.
  3. Once you opened other tabs because you searched …

RubyMine: Set specific Ruby version per project

If your project uses another version than your default Ruby, RubyMine will give you incorrect inspections, for example.\
Here is how to switch which Ruby you use in RubyMine.

  1. File → Settings (Or press Ctrl+Alt+S)
  2. Select "Ruby SDK and Gems" from the left pane
  3. Switch your "Ruby interpreter".

Though it may seem you are changing a global setting here, this is in fact a per-project setting, as are all things you change in the "Project Settings [your_project_name]" area of the global settings dialog.

When you switch to another proje…

How to fix: RubyMine does not remember last used monitor (on Ubuntu)

Every time I started RubyMine, it opened the main window on the left monitor – when moving it to the center monitor and closing it, the next time it still opened up on the left one.

Here is how I forced RubyMine to start up on a different screen:

  1. Un-maximize the main window
  2. Move it to your preferred monitor
  3. Close RubyMine (keep it unmaximized)
  4. Start RubyMine again.
  5. You may now maximize your main window; the next time you start up RubyMine, it will open on the correct screen, maximized.

That's crazy!

RubyMine: Disable window animations

Under Settings / Appearance you can uncheck a box Animate windows. This will change your life.

RubyMine: Find and execute a menu action by its name

You are looking for a functionality in RubyMine but don't know or remember its keyboard shortcut or which menu it is located in?\
Hit Ctrl+Shift+A.

This will bring up the "Find Action" box where you can enter an action's name or category. Pick the result from the list to run it.

The list of results will also show you any assigned keyboard shortcuts.

RubyMine: Exclude data and log directories from a project

RubyMine offers you to exclude directories from search, meaning faster search results and less "noise" in the list of result.

Right-click a folder in your project tree and click "Mark Directory As" → "Excluded".

Do it for your your log, data, and other directories that you don't need to access during development and whose search results are irrelevant.
They won't be deleted but simply ignored when searching across a project's files.

Using heredoc for prettier Ruby code

You can use heredoc to avoid endlessly long lines of code that nobody can read. It looks like this:

def long_message
  puts(<<-EOT)
    Here goes a very long message...
    Sincerely,
    Dr. Foobear
  EOT
end

<<-EOT will be somewhat of a placeholder: anything you write in the line after you used it will be its value until you write EOT in a single line.

You can use any string to flag your heredocs. T0 be more verbose you can use something else – your IDE may e…

Solarized color scheme for Rubymine

If you want to use the (badly implemented!) solarized color scheme in your Rubymine IDE:

  1. Clone the IntelliJ IDEA port:

    git clone https://github.com/jkaving/intellij-colors-solarized.git

  2. Import the settings in Rubymine by chosing the above directory File -> Import Settings

  3. Change the color scheme in the settings (Ctrl-Alt-S) in Editor -> Colors & Fonts

Note that selecting a color scheme will also reset your previous editor font choice. You might want to change the font to [Envy Code R](http://damieng.com/blog/2008/05/2…

RubyMine crashes Ubuntu 11.04 window decorator on exit

My RubyMine (and it seems like many other Java GUI applications) crashes the Compiz window decorator almost every time on exit. This also seems to happen for the Unity decorator.

Update: The commited fix from below seems to have made it into the stable Ubuntu repository.

Easy mode

You can restore window decorations by executing this command:

gtk-window-decorator --replace &

This is only a temporary fix.

Hard mode

Also, there is a committed fix that is n…

How to upgrade RubyMine

This card explains how to upgrade an existing RubyMine installation to a newer version. If you're installing RubyMine for the first time, see install RubyMine under Ubuntu. You might also consider installing RubyMine with snap, so it can receive automatic updates (also described in the install card).


This procedure ensures that an update does not totally break your IDE, as it allows you to keep both the previous and the new version of RubyMine:

  1. [Download the newest version](http://www.jetbrains.com/ruby…

Opening Rubymine projects from the command line

To activate the shell command, go to Tools > Create Command-line Launcher and confirm.

Now you have mine as bash command. Run this to open a project in RubyMine:

mine path/to/my_project

Booting Rubymine

The mine script will attach the opened project to a current Rubymine instance. If there is none, it will run Rubymine right there on your command line.

To move Rubymine to the background and suppress log messages you can create your own shell script (vim ~/bin/rubymine):

```
#!/bin/sh
( mine "$@" & ) > /dev/null …

Install RubyMine under Ubuntu

This card explains how to install RubyMine for the first time. If you want to upgrade an existing RubyMine installation (after legacy install) to a newer version, see How to upgrade RubyMine.


Option A (new way)

Ubuntu 16.04 comes with snap, a way to package software with all its dependencies. RubyMine is also packaged as a snap.

A snap will always track a channel (like stable, beta) and automatically update to the newest version available in this channel. By default the snap daemon will check for …

Force RubyMine to notice file system changes

If you did file operations inside a shell or for example using Nautilus, it can take quite a while until RubyMine takes note of them and updates things like your project tree or its internal file list.

Flushing file system buffers helps you out (run it from a terminal):
sync

This is also possibly via the RubyMine menus: File → Synchronize.

Sun Java JVM/JRE on Ubuntu Linux

Note that you should disable the Java plug-in in your browsers after installation.

Ubuntu >= 12.04

Java 11

sudo apt install openjdk-11-jre-headless

Java 10

sudo add-apt-repository ppa:linuxuprising/java
sudo apt-get update
sudo apt-get install oracle-java10-installer

Java 8

You probably want to get rid of OpenJDK (which is installed by default and leads to bad RubyMine performance):

Enable tab dragging in RubyMine

Since RubyMine 3.1 you can drag tabs across panes/windows and out of the main window to create new windows.

For any version below 3.1 do it like this (will only allow dragging tabs inside their pane, not across panes):

  1. File → Settings
  2. Editor → Editor Tabs
  3. Check "Show tabs in single row"
