RubyMine comes with a nice way to grep through your project's files: The finder (ctrl + shift + f). Don't be discouraged about the notice 100+ matches in n+ files if your searched keyword is too general or widely used in your project.

RubyMine comes with a few ways to narrow down the resulting list, don't hesitate to apply those filters to speed up your search. Your keybinding might vary based on your personal settings.

If you already know the file extension of your ...

If your Rubymine does not recognize a file type correctly although you have entered the unmistakeable file extension like material_orders_controller.rb, this may help you:

Causing the Problem

Sometimes you create a new file and forget to enter the ending like material_orders_controller
Rubymine handles such files per default as simple txt files.
You delete this file and create a new one with correct ending: material_orders_controller.rb. But still Rubymine treats this file as text file, no highlighting is available.

Grazie Lite

Rubymine 2024.3 bundles Grazie Lite by default. You need to enabled "German" under Settings/Preferences | Editor | Natural Languages.

Hunspell (legacy)

1. Install the Hunspell plugin and restart Ruby Mine
2. Run sudo apt install hunspell-de-de

When you find yourself constantly ignoring a RubyMine warning, you can simple disable that warning and de-clutter your editor. E.g. in my Cucumber scenarios RubyMine underlines 90% of all lines because it does not know about spreewald, making the file really hard to read.

You can disable any unwanted inspection by opening File / Settings / Editor / Inspections and searching for the warning text.

What you disable or keep is up to your personal preference. I personally disable at least the following...

If another session is accessing your database you are trying to reset or drop you might have seen the following error:

PG::ObjectInUse: ERROR:  database "foo_development" is being accessed by other users
DETAIL:  There is 1 other session using the database.

This could be the rails server, rubymine and many more. Beside terminating the session connection manually you can also find out the pid and kill the process.

1. rails db
2. SELECT * FROM pg_stat_activity;

RubyMine provides a visual tool for resolving merge conflicts locally.

Follow

Git > Resolve Conflicts

in the context menu to open RubyMine's merge conflict tool.

• Left pane: local copy (read-only)
• Right pane: checked in version from repository (read-only)
• Central pane: base revision from which both conflicting versions are derived

You can also use a similar pane view to compare to files.
Mark two files and press Ctrl + D to compare.

RubyMine allows bookmarking lines of code. This is super-helpful when working on a complex problem.
I've been using this feature for a few years now, and so should you! :)

Here are the default Linux/Windows keystrokes. See the documentation for other keybindings.

Add an anonymous bookmark

F11

A gray checkmark will be shown in the gutter on the left.
If you press F11 again on a bookmarked line, the bookmark will be removed.

Add a named bookmark ("mnemonic")

Sometimes your code has long lines:

describe 'foo' do
  describe 'bar' do
    really_long_line_really_long_line_really_long_line
    another_line

When you're working with multiple editor panes, such code will often be wider than the pane area:

describe 'foo' do                |
  describe 'bar' do              |
    really_long_line_really_long_|
    another_line                 |

To help with this you can activate Soft wraps in the RubyMine options under General → Editor .

Your code will now look like this:

Many of our developers love to use the "awesome" window manager on Linux. However, RubyMine dialogs occasionally defocus while typing.

Here is a fix for that, tested on awesome 3.4, 3.5 and 4.0 (Ubuntu 14.04 and 16.04).

Problem

Consider the following:

1. Press Ctrl+Shift+N
2. "Find file" dialog opens
3. Type to search, file list appears
4. Type more, file list is being replaced

If your mouse pointer hovers the file list, the main window is focused when the list is being replaced (or simply when it shrinks and your mouse pointe...

When you paste copied code with CTRL+V, RubyMine will change the indentation of the pasted code. You can prevent this by pasting with CTRL+ALT+Shift+V instead ("Paste Simple").

To change this behavior entirely, you can open your settings and navigate to Editor / General / Smart Keys. Here you can select one of three options for Reformat on paste:

• None
• Indent Each Line (default)
• Indent Block
• Reformat Block

You might want to try "Indent Block".

From time to time, RubyMine suddenly did not accept any keyboard input and felt crashed, while mouse interaction was still possible. This apparently happens to all IntelliJ IDEs, especially on Ubuntu 14.04.

I've managed to fix it by having a shell script that exports XMODIFIERS="" when launching RubyMine, like this:

#!/bin/sh
XMODIFIERS= /home/arne/rubymine/bin/rubymine.sh

It has been working reliably for me ever since, at least until RubyMine 8.

An alternate solution suggested on the [Jetbrains issue tracker](https://youtrack....

By pressing Ctrl + Shift + V you can select a recently copied string for pasting.

Navigation

CTRL + SHIFT + ALT + N

Search for any symbol in your application, like CSS classes, Ruby classes, methods, helpers etc.

CTRL + SHIFT + N

Search for filename in your application (also dependencies)

CTRL + E

Open a list of recently opened files

ALT + POS1

Open a the navigation bar as a context menu. Allows you to quickly navigate between files.

CTRL + G

Go to line

In my RubyMine I have recorded two macros for debugging and linked them to some keyboard shortcuts. Since I believe everyone could benefit from having those I wanted to share this.

The first one simply inserts

binding.pry

and the second one

.tap { |object| binding.pry }

for when you do not have a reference to the object you want to inspect.

In order to record a macro you simply follow the path Edit > Macros > Start Macro Recording.

Then you simply type binding.pry or whatever you want to record and stop recor...

I was annoyed that RubyMine's autocompletion did not work via Ctrl+Space for me. In fact, it did not work in any application.

Turns out that keyboard combination was hijacked by Ubuntu as it's the default for switching input languages (i.e. keyboard layouts). If you use only 1 language/layout, you will not notice except for the key not working.

To fix it, do the following:

1. Run ibus-setup (e.g. from a terminal). This will open a GUI dialog.
2. In the 1st tab you should see "Next Input Method" followed by "<Control>space".
3. Click t...

Code folding is a very useful feature to me. It gives me a quick overview over a file and keeps me from scolling like a hamster in its wheel.

Keyboard shortcuts:

Collapse/expand current code block

strg -/+

Collapse/expand the whole file

strg ctrl -/+

When diving into Cucumber features or huge Ruby classes, I usually collapse all and the gradually expand what I need.

One of the many useful features of TextMate is autocompletion of words. If I were in TextMate right now, I could write "au[tab]", and it would complete it to "autocompletion". RubyMine can do this, too. When you write a word (e.g. a variable name), just hit ALT + / repeatedly and it will offer all completions for the letters you typed. This action is called Cyclic Expand Word in RubyMine / IntelliJ IDEA.

This feature keeps you from mistyping variable names, saves you keystrokes and speeds up development. ~10 keystrokes to the price ...
