I'm used to the sublime text 3 editor.
It has many handy features.
take the code snippets for example,
Once you type begin then press TAB
It will generate the corresponding code block
begin
rescue Exception => e
end
And the plugin All Autocomplete
It can show the auto-complete hint for all opened files.
For example, if you have a variable name called taiwan_is_awesome
then you can get the autocomplete in other files.
Does Rubymine has the above features ?
If yes, what's the corresponding keymap ?
It's important for me to use those features.
THanks
Once you type begin then press TAB
It's called "Live Templates".
"Live templates (or code snippets) allow you to insert frequently-used constructions into your code. These can be conditions, blocks, loops, and so on."
You can manage bundled and create new ones at Settings/Preferences | Editor | Live Templates.
Here is a good "how to use" tutorial with screenshots: https://confluence.jetbrains.com/display/PhpStorm/Live+Templates+%28Snippets%29+in+PhpStorm -- it's for PhpStorm but exactly the same functionality is available in RubyMine.
UPDATE: 2022-11-15
The above tutorial link now automatically redirects to the corresponding Help page for PhpStorm.
Here is the same official Help page but for RubyMine that shows how to use and create them: https://www.jetbrains.com/help/ruby/using-live-templates.html
The setting you want to make RubyMine code completion work like All Autocomplete in Atom & ST3 is called "Autopopup code completion".
Solution:
Settings > Editor > General > Code Completion > "Autopopup code completion"
Note: there is another type of code completion called "Hippie Completion".
However, it works differently than "All Autocomplete". In RubyMine "Hippy Completion", you start typing text, and then you have to "guess" when RubyMine has enough text to figure out the completion you want. Then you hit ⌥/ (on the Mac). If RubyMine guesses right, it will autocomplete correctly.
I greatly prefer the "All autocomplete"/"Autopopup code completion" method, but just thought I'd mention this alternative.

When writing JSX (or any typescript code really) if you have an available import that's not yet imported, you get a squiggly line under it and can press ctrl+dot on it and then automatically import the code as a "refactoring."
How can I set this up in Javascript? I've seen a screenshot of someone else's VSC where it is available underneath "more options" and so I'm pretty sure it's possible, but when I press ctrl+dot I get nothing.
Note: I'm aware I can press ctrl+space. However, I don't want to do this, for two reasons. (1) alt+space is pretty bad UX because if you press it in the middle of a word it continues to autocomplete even if you already had the full name there and so you are left with an incorrect tag (e.g. if your cursor was after the d in Keyboard for a component called KeyboardRow you are left with KeyboardRowRow) and (2) I want to rebind quick fix to alt+enter to match pycharm; and I want the same hotkey & UX in both Typescript and Javascript.
I haven't worked too much with JS, mainly with TS, but I have two extensions installed in my vscode that helped me a lot while coding in vanilla JS.
Path intellisense and Auto import
You can try if My Code Actions can be used to construct a Quick Fix for these types of PROBLEMS/squiggles
I've recently started using the Visual Studio Code editor. I'm really loving it, but there's one critical feature (for me) that I haven't been able to find. Is there a method list, similar to the Navigator in NetBeans or Member dropdown in Visual Studio?
Yes, there is the workbench.action.gotoSymbol command. On Windows and Linux it's set to CTRL+Shift+O by default, on Mac it's Cmd+Shift+O.
If this command isn't available for the file types you are working with then you should take a look at the VSCode extensions. Not all languages support this feature.
Update: As stated in the comments by #jeff-xiao this extension is Deprecated and it's now a built in feature of Visual Studio code. It should be available at the bottom of file explorer as "Outline" view.
Previous text:
There is now an Extension that supports this. Code Outline creates a panel in the "Explorer" section and for JavaScript, will list variables and functions in a file. I've been using this for a while now and it scratches the itch I had. Other commenters have mentioned it supports Python and PHP well.
It still seems to be in development but I haven't had any issues. Development version available on GitHub. If you're the author reading this - thanks!
This is how it looks:
If Code Outline is not visible, you can show it by:
Invoke Code's Go to symbol command:
macOS: cmd+shift+o (the letter o, not zero)
Windows/Linux: ctrl+shift+o
Typing a colon (:) after invoking Go to symbol will group symbols by type (classes, interfaces, methods, properties, variables). Then just scroll to the methods section.
In 2020 version of VSCode
Cmd+P
# - Find symbol across files
# - Find symbol within file
#: - Group symbols within a file
In VSCode 1.24 you can do that.
Right click on EXPLORER on the side bar and checked Outline.
There is a new release that can do that!
Check here the latest release notes regarding code outline
UPDATE: The extension features are now built-in and the extension itself is now deprecated
I have found this extention: Code Outline.
This is how it looks like:
I believe that is what you have been looking for.
There's no such feature today,
the CTRL+SHIFT+O == CTRL+P # doesn't work for all languages.
As a last resort you can use the search panel - although it is not so fast an easy to use as you'd like - you can enter this regex in the search panel to find all functions:
function\s([_A-Za-z0-9]+)\s*\(
For PHP users :)
Make sure you have 'PHP Symbol' plugin then you can get all methods and class in 'OUTLINE' Sidebar's Bottom.
Press ⌘ command + ⇧ shift + O in "macOS" or Ctrl + Shift + O while using "Windows"
OUTLINE:
#Symbol:
For python in Explorer View, click on OUTLINE as below:
Visual Studio Code market place has a very nice extension named Go To Method for navigating only methods in a code file.
Hit Ctrl+Shift+P and type the install extensions and press enter
Now type Add to method in search box of extensions market place and press enter.
Click install to install the extension.
Last step is to bind a keyboard shortcut to the command workbench.action.gotoMethod to make it a real productivity thing for a developer.
Watch this link: https://code.visualstudio.com/updates/v1_40#_type-filters-for-outline-and-breadcrumbs
Explorer -> OUTLINE, you can choose what you want to show (only methods and functions in your case) and the result is similar to Netbeans:
Open symbol by name :
CTRL+T
might be what you are looking for. Works perfectly with my TypeScript project.
It is an extra part to the answer to this question here but I thought it might be useful. As many people mentioned, Visual Studio Code has the OUTLINE part which provides the ability to browse to different function and show them on the side.
I also wanted to add that if you check the follow cursor mark, it highlights that function name in the OUTLINE view, which is very helpful in browsing and seeing which function you are in.
ctrl+shift+o // This should work for javascript files by default
For PHP install the extension PHP SYMBOLS
FOR PYTHON install the extension PYTHON
On Reload, this will work fine
in-built code OUTLINE available now with VS code
There is a plugin called show functions which lists all the function definitions in a file. It also allows you to sort the function so can search them easily.
CTRL+F12 (CMD+F12 for Mac) - opens for me all methods and members in PHP class.
For find method in all files you can press CTRL + P and then start search with #
example : #signin
Take a look at Show Functions plugin.
It can list functions, symbols, bookmarks by configurable regular expressions. Regular expressions are a real saver, expecially when you're not using a mainstream language and when CodeOutline doesn't do the job.
It's ugly to see a split window with these functions (CodeOutline seems to be better integrated) but at least there's something to use
If you are using typescript you can use this extension "Code navigator for typescript".
I have been trying it and found it useful to list my typescript class methods.
I'm not sure if this is possible and if this is the right place to ask, but I'd like to give it a try. I'm currently trying Netbeans IDE, coming from Dreamweaver.
In Dreamweaver I can create Code Snippets and bind a key to them. So for example marking a text and pressing CTRL+B then, surrounds the text with the [strong] tag. Or I created a snippet, when I press SHIFT+CTRL+B it adds a [br /] tag at the position of the cursor.
I could not find a way to do this in Netbeans so far. Does anyone know if this is possilbe, and if, how to achieve this?
There is a Plugin available for that,
Go to Tools->plugins and try out TagMyCode
https://tagmycode.com/
I've been using it for quite some time, there is a library of public snippets and the doc is really helpful.
Coming from Visual Studio and starting a project in Java, I realized I couldn't cope with having to press ctrl+space to have the autocomplete panel show up. An easy workaround was to set all keyboard characters to be trigger characters for autocompletion.
My only problem is that, when presented with autocomplete suggestions, a single press on the space bar will write the first proposition. In situations where I'm happy with the suggestions, that's just fine. In situations where I actually want to use what I wrote down initially, I have to press 'escape' first to remove the autocomplete panel before I can press 'space' safely.
Netbeans doesn't use the space bar as a validating key for autocompletion (only 'enter' does that) and I like that behavior. Any way to replicate it in Eclipse?
Thanks in advance for your answers!
EDIT: I should have mentioned I'm using Eclipse on the Mac.
Guillaume
I have the same problem with Eclipse Indigo on Windows XP actually. Coming from intellij idea, I also felt the need to set the whole keyboard to trigger auto-complete.
A quick proof that SPACE key does accept suggestions : type inte on a new line. If the auto-complete menu shows, press SPACE. It goes for Integer.
If anyone knows how to set the SPACE key to "ignore suggestions", it would be great, because the escape key on my keyboard is also too far away :)
Thanks
Edit : actually the best would be to have only the ENTER key validating, because ';' and '(' also seem to validate
I just tried to reproduce your behavior, but couldn't. Here is the configuration I have (and the steps I have done to reproduce):
I have installed Indigo (current version of Eclipse, version number 3.7).
I did not change any configuration there, this is what is the default:
Under Window > Preferences > Java > Editor > Content Assist, I have the following settings:
Completion inserts (instead of overwrite)
Insert single proposal automatically (which is ok most of the time)
not insert common prefix automatically
I have a simple class, go down to a method, and do the following steps:
Enter this.no and wait some time. Sometimes I have to press CTRL + SPACE, sometimes not.
Proposal pops up which includes notify and notifyAll.
I press SPACE and a space is inserted in the text, the autocomplete suggestions are closed without inserting anything.
I do not know if older versions of eclipse have the same behavior.
Closed. This question is opinion-based. It is not currently accepting answers.

I have been using Eclipse as an IDE for a short amount of time (about 3 months of full use) and almost every day I learn about some shortcut or feature that I had absolutely no idea about. For instance, just today I learned that Ctrl+3 was the shortcut for a Quick Access window.
I was wondering what your most useful/favorite Eclipse features are. With the IDE being so big, it would be helpful to learn about the more commonly used parts of the program.
My most commonly used features are
ctrl+1 quick-fix / spell-checker
opening files
ctrl+shift+t load class file by classname
ctrl+shift+r load any file by filename
matches are made on the start of the class/filename. start your search pattern with a * to search anywhere within the filename/classname.
Formatting
ctrl+shift+f Format source file
(set up your formatting style in Window | preferences | java | code style | formatter)
ctrl+shift+o Organise imports
Generated code
alt+s,r to generate getters and setters
alt+s,v to insert method signatures for overidden methods from superclass or interface
Refactorings
alt+shift+l Extract text-selection as local variable (really handy in that it determines and inserts the type for you.
alt+shift+m Extract text-selection as a method
alt+shift+i inline selected method
Running and debugging.
alt+shift+x is a really handy prefix to run stuff in your current file.
alt+shift+x, t run unit tests in current file
alt+shift+x, j run main in current file
alt+shift+x, r run on server
There are more. The options are shown to you in the lower-right popup after hitting alt+shift+x.
alt+shift+x can be switched for alt+shift+d in all the above examples to run in the debugger.
Validation
As of the recent Ganymede release, you can now switch of validation in specified files and folders. I've been waiting for this feature for ages.
Go to Project | Properties | Validation
click on the ... button in the settings column of the validator you want to shut up
Add a rule to the exclude group
code navigation
hold down ctrl to make all variables, methods and classnames hyperlinks to their definitions.
alt+left to navigate back to where you clicked ctrl
alt+right to go "forwards" again
This is cool: If someone has emailed you a stack trace, you can copy and paste the stack trace into Eclipse's Console window. You can then click on class names in the stack trace as if your own code had generated it.
In terms of actual features, rather than shortcuts, I strongly recommend taking a look at Mylyn.
It essentially skins Eclipse with a task focussed view. It tracks the files you touch when working on a task, and focusses many aspects of the UI onto the resources that it decides are relevant to the job in hand. Eclipse can be somewhat busy to look at, especially with a big multi module project, and Mylyn helps cut through the cruft. The connectivity to issue tracking software and source control repositories is also excellent.
In my experience, it polarises opinion amongst those who try working with it, which is probably a sign that it is offering something interesting... Don't mean to sound like a fanboy - it is definitely worth a look though.
A shortcut that I use everyday is Ctrl+K. In your editor (not only Java file), simply select a text (like a variable, a function, etc.), and then use this shortcut to go to the next occurrence of this text in the current editor.
It's faster than using the Ctrl+F shortcut...
Note also that you can use Ctrl+Shift+K to search backwards.
Ctrl-Alt (up/down) Copy selected line(s) above or below current line.
Alt (up/down) Move current (or multiple selected) lines up or down
Ctrl-Shift-R Bring up the resource window, start typing to find class/resource
Ctrl-O Bring up all methods and fields for the current class. Hitting it again will bring up all methods and fields for current class and super classes.
Ctrl-/ or Ctrl-Alt-C Comment single or multiple lines with //
Ctrl-Shift-/ Comment selected lines with /* */
Ctrl-. Take you to the next error or warning line
CTRL+PAGE DOWN / CTRL+PAGE UP to switch between opened editors
CTRL+E to also switch between opened editors (allows to type the name)
CTRL+O is extremely important for me. You don't longer need the Outline View then (you can close it which will give you more space). Then, you can type a method name or just the beginning of it and you quickly can get to it. I also use it to inspect what stuff is available. For example: CTRL+O and then type get ... now I see all getters.
F3 while an element is selected in the code: brings you to its definition or it's source. e.g. used on a method call it brings you into the source code of that method.
CTRL+M to maximize the current window
As already said, CTRL+3 is extremely good. It basically allows you to use Eclipse completely without a mouse. Just type CTRL+3 and then package explorer for example.
CTRL+F8 cycle trough perspectives
CTRL+L allows to type a line number and brings you directly to that line.
CTRL+SHIFT+G searches for all references to the selected element in the workspace.
And not a shortcut: In the project settings under Java Editor you can find Save Actions. This allows you to set up the project so that the code is automatically cleaned up and formatted when you save a file. That's very good it safes you from constantly pressing CTRL+O and CTRL+F.
Eclipse auto refresh isn't on by default so if you make changes to a file outside of eclipse, the change won't be reflected in your build. this is very annoying if you just did an svn/git update/rebase and things aren't working the way they're supposed to.
Turn it on in windows->preferences->workspace and tick Refresh Automatically.
Local History
It's a great feature. Eclipse has its own mini-CVS for all files in a project. If you want to revert some change you made, or even restore deleted file - you can right click on the project and select "Restore from Local History".
Just saved my ass *tears of joy*
CTRL+Shift+P to jump to the matching bracket/parenthesis.
One key feature: Shift+Alt+T for the refactoring menu.
Ctrl-shift-T, but only type the initial characters (and even a few
more) of the class you're looking
for. For example, you can type
"NetLi" to find NetworkListener
In the Search window, Ctrl-. takes you to the first leaf of a tree branch
Alt-/ is Word Completion. Slightly different from Ctrl-space
CTRL+SHIFT+X selected text becomes UPPERCASE
CTRL+SHIFT+Y selected text becomes lowercase
I'd like to add two additional shortcuts:
CTRL+F6 Switch between open editors (CTRL+SHIFT+F6 to scroll through the list in the opposite direction)
CTRL+F11 start program in debug mode
F11 start program in normal mode
A lot of the key bindings depend on the perspective and view currently active.
My most used ones for the Java perspective:
ctrl-shift-r open resource
ctrl-shift-t open type
ctrl-1 quick fix/refactor
ctrl-j incremental search
ctrl-h search in files (select a base directory and set scope to selected resources)
ctrl-o list methods
ctrl-alt-h open call hierarchy
ctrl-shift-l list shortcut keys
hit ctrl-shift-l again to go directly to preferences to change key mappings
I am also a fan of Eclipse, however since I spend a majority of my time in Visual Studio, I will suggest that you read Eric Sink's series of articles "C# to Java" (parts 1-4). Not only is Eric always an entertaining read, but this brief series covers some awesome Eclipse insight for those who have not been into Eclipse or have been away from it for a while:
From C# to Java: Part 1
From C# to Java: Part 2
From C# to Java: Part 3
From C# to Java: Part 4
Ctrl-Shift-M while the cursor is on a class name in your java file, will specifically add that and only that class to your imports. This is different from Ctrl-Shift-O which will not only add those imports not already defined, but will also remove imports not currently needed, something you might not necessarily want to do.
I forgot about [Ctrl+2 -> r] scope variable rename. Place the cursor in the variable you wish to rename, press Ctrl+2, then r, then type the new name watching all instances of that variable get renamed at the same time.
It's awesome at refactoring Hungarian Notation.
alt-shift-a is extremely useful in a few situations.
I use a lot of the above and also like for quick search: CTRL+J then type what I am looking for, then CTRL+K for next occurrence.
Lately I've been using the MouseFeeds plugin to automatically tell me what the key stroke combinations are. That way by repetition I remember them better.
This link has a better picture and description of what it looks like and does.
Shift+Alt+b for the simple navigation row over the editor.
I've just released this blog post about Top 5 Useful Hidden Eclipse Features. It contains:
Favorites: Types and members that will always show up in auto-completion
The awesome block selection mode: For multi-line editing
The EGit staging view: Much better than git itself
Type filters: To remove awt and java.lang.Object stuff from auto-completion
Formatter tags: To delimit code sections that shouldn't be auto-formatted
Alt+left and Alt+ right will navigate you forward and back.
I find the project-specific settings useful in Eclipse 3.3.
For example, if you have several developers working on a project who have different code styles for curly braces, line spacing, number of imports etc. then you can specify the style settings for the project. Then you can configure the save actions so that the code is automatically formatted when a file is saved. The result is everyone's code is formatted the same before it's checked in.
