As developers, we create, update, and delete files all day long. Managing files from the command-line is one of the first skills we learned. However, constantly switching from your editor to the command-line to execute a simple file command, a command you’ve probably executed thousands of times before, is tedious and slow. Instead, stay in your editor, and let it take care of the boring stuff. In this post, we’ll look at RubyMine’s file commands on OS X.

Creating Files

To create a new file or directory, press control + alt/option + N within the editor or Project tool window.

Copying Files

Use F5 within the editor or Project tool window to copy the current file.

F5 can also be used in the Project tool window to copy directories.

Cloning Files

To create a copy of a file or directory in the current directory, press shift + F5.

Moving Files

Move files and directories with F6.

Like the previous file commands, this command works both within the editor and Project tool window.

Renaming Files

Files and directories can be renamed in the Project tool window with shift + F6.

Deleting Files

Delete files and directories in the Project tool window with delete.

Locating Files

To locate a file in the Project tool window, press alt/option + F1 in the editor, and then select the Project View option, the default option, from the Select Target dialog.

Select Reveal in Finder to open the file in a new OS X Finder window.

Working with File Paths

Use command + alt/option + F12 to view the complete file path.

Selecting a directory will open the directory in a new OS X Finder window.

Copy the current file path to the clipboard with command + shift + C. Copy a reference, the current relative file path and line with command + alt/option + shift + C.

These commands are useful for when you need to work with a file on the command-line.

Relying on Abstractions

A common developer fear is that overreliance on a particular IDE’s features will cause you to forget, or maybe never learn, the underlying commands. I agree that in some cases, e.g., version control, it’s important to know what’s going on under the hood. However, these situations are rare. And when it comes to everyday commands, I’d much rather use higher-level abstractions to free me from the mundane.

A typical Rails development environment includes an editor, a terminal for running a web server, and a utility terminal for managing files, using version control, running tests, etc. During development, you’re constantly switching between your editor and these external terminals. RubyMine, an Integrated Development Environment, can eliminate this tedious back and forth workflow. In this post, we’ll learn how to run programs in RubyMine on OS X; allowing you to stay in RubyMine all day long.

Running Files

To run a file, open the file in the editor or select the file in the project tool window, then press control + shift + R. Rerun a file with control + R.

These commands are commonly used to run test files, but they could also be used to run a simple Ruby script.

Run Tool Window

All running programs are displayed in the Run tool window. Press command + 4 to open the Run tool window.

Stop a running program with command + F2. Use command + shift + [ and command + shift + ] to navigate between multiple running programs.

Running Tests

In a test file, press control + shift + R outside of any individual test to run all the tests in the file. Press control + shift + R within an individual test to run just that test.

Run Dialog

Open the run dialog with control + alt/option + R. The run dialog lists recently run programs. This is useful for when you want to rerun a test you ran several tests ago.

By default, this dialog also includes commands to run a development server, and your entire test suite.

Ruby/Rails Quick List

Use command + option + R to open the Ruby/Rails quick list. The Ruby/Rails quick list includes several useful commands such as, starting a Rails console, and starting an IRB session.

You can run a file or a code selection in an existing IRB or Rails console with alt/option + shift + L. View IRB history with command + E.

Running Rake Tasks

Run a Rake task with alt/option + R.

If a custom Rake task doesn’t appear in the list, reload Rake tasks from this dialog or the Ruby/Rails quick list (command + alt/option + R).

Running Rails Generators

Run a Rails generator with command + alt/option + G.

If a custom Rails generator task doesn’t appear in the list, reload Rails generators from this dialog or the Ruby/Rails quick list (command + alt/option + R).

Take Advantage of Your IDE

IDEs increase your productivity by combining all of your development tools into one program. Frequent context switching to external tools not only slows you down, but also requires more in-depth knowledge of each tool. Try gradually replacing external tools with their IDE equivalents. Over time, your knowledge of shell command options and obscure Git commands will no longer seem very important to you.

In RubyMine, you can create tasks to breakdown and structure your work. A task can be a simple local task, or it can correspond to a feature, bug, or chore, in an issue-tracking system. Each task in RubyMine includes the current state of the editor, allowing you to switch between tasks and resume exactly where you left off. In this post, we’ll explore RubyMine’s tasks on OS X.

Creating Tasks

Press alt/option + shift + N to open the task dialog. Enter the task’s name, then press Enter to create the task.

By default, RubyMine will clear your current context and create a new changelist.

Switching Tasks

A context is a set of opened files. Each task has an associated context. When you switch tasks, its context is automatically loaded.

To switch between tasks, use alt/option + shift + T.

Isolating Work with Changelists

A changelist is a set of related source code changes. Each task has an associated changelist.

Changelists allow you to isolate each task’s changes. Use command + K to commit the current task’s changelist. RubyMine will now consider the task closed, and ask if you want to delete its changelist.

Pivotal Tracker Integration

Instead of manually creating tasks, you can configure RubyMine to load tasks from Pivotal Tracker.

In project settings, command + ,, create a new Pivotal Tracker server in the Tasks Servers section. Then add your Pivotal Tracker project id (located in the Pivotal Tracker project’s settings page) and API token.

Pivotal Tracker stories will now appear in the task dialog.

Creating a new task from a Pivotal Tracker story allows you to update the story as in-progress. However, it won’t set you as the owner of the story. Also, closing the task won’t finish the story.

Clean Context Switching

RubyMine’s tasks are well-suited for serial development. But if you constantly switch contexts, like most developers, they fall short, because switching tasks brings along committed work. If each task consists of a single commit, then this isn’t a problem. However, I prefer to commit frequently; resulting in many small, granular commits. So, in my opinion, using a distributed version control system, e.g., Git, and a branch-per-feature workflow, is a better development strategy than RubyMine’s tasks. Branches keep your work isolated from the main line of development, and it’s still possible to cleanly switch contexts.

When browsing a codebase, you often want to view the definition of a particular class, method, or variable. However, sometimes you want to do the reverse; you want to see where a particular class, method, or variable is used. Typically this involves using your editor’s text search, or a command line tool, such as grep or ack. Unfortunately, text searches may return false positives, such as log file data, or similarly named constructs. The problem is that you want to search code not text.

RubyMine has text search, but it also includes a powerful, code-based usage search. Usage search is smarter than text search, because RubyMine is aware of code constructs such as classes, methods, and variables. This results in a more accurate search; allowing you to quickly view and navigate actual usages. In this post, we’ll explore RubyMine’s usage search on OS X.

Find Usages

To find where a particular class, method, variable (instance or local), or parameter is used, place your cursor on it, and press alt/option + F7. Results will be displayed in the Find tool window.

command + alt/option + Up/Down navigates the results. Use F4 to jump to the source code of a particular usage.

Recent usage search results can be viewed again with command + E.

Find Usages in File

By default, find usages is scoped to the entire project. To scope it to the current file, use command + F7. command + G and command + shift + G navigate the results.

Show Usages

command + alt/option + F7 can be used to show usages inline. Instead of displaying usages in the Find tool window, they appear in a pop-up window.

Searching Code

RubyMine’s usage search demonstrates an advantage an IDE has over a text editor. By being aware of code constructs, such as classes, methods, and variables, IDEs can offer powerful tools that allow you to quickly and accurately explore a codebase.

Like many text editors, RubyMine supports bookmarks. A bookmark is a reference to a particular line in a file. They are visually indicated by an icon in the editor gutter. Bookmarks can be used as a form of navigation based on interested parts of a codebase. In this post, we’ll explore (using the Mac OS X 10.5+ keymap) the three types of bookmarks in RubyMine: anonymous, numbered, and lettered.

Anonymous Bookmarks

Anonymous bookmarks can be created with F3. They appear as a checkmark icon in the editor gutter.

Unfortunately, there are no default keyboard shortcuts to navigate anonymous bookmarks. Instead, use the Find Action command,command + shift + A, to search for the “Next Bookmark” and “Previous Bookmark” anonymous bookmark navigation commands. These commands will only navigate through anonymous bookmarks in the current file.

Mnemonic Bookmarks

There are two types of mnemonic bookmarks: numbered and lettered.

Numbered Bookmarks

You can have up to 10 numbered bookmarks: 0-9. To create a numbered bookmark, press control + shift + <number>, e.g., control + shift + 4.

To navigate to a numbered bookmark press control + <number>, e.g., control + 4.

Lettered Bookmarks

You can have up to 26 lettered bookmarks: A-Z. To create a lettered bookmark press option + F3, then choose a letter to use for the bookmark.

To navigate lettered bookmarks, use the bookmarks dialog (discussed below), command + F3.

Deleting Bookmarks

All three types of bookmarks can be deleted by pressing F3 when on the bookmarked line.

Viewing Bookmarks

You can view all existing bookmarks with command + F3.

This dialog also allows you to delete, and navigate bookmarks.

Last Edit Location “Bookmark”

When editing, it’s common to stop for a second to view another part of the file (or a different file), and then navigate back to the original edit location.

Instead of using bookmarks to quickly navigate back to the original edit location, use the Last Edit Location command, command + shift + Backspace.

Experimenting with Bookmark Navigation

After trying out the different types of bookmarks in RubyMine, I find numbered bookmarks to be the most useful. They are both easy to create and navigate. Lettered bookmarks offer a greater number of possible bookmarks, but navigating them requires several commands. I think anonymous bookmarks could also be useful, if you create shortcuts for their navigation commands.

Try them all and see what works best for you.
