In editplus we can define autocompletion keywords to insert pieces of code or blocks of code automatically.
For eg. if I've defined something like below
#T=ecp
echo '<p>' . ^! . '</p>' . "\n";
#
and now, whenever I type ecp I get the above code inserted automatically with cursor placed in the place of ^!.
I'm looking for a similar setting / function or a way to do the same.
Any ideas please ?
Thanks in advance
Emacs has Abbrev Mode, it also has a variety of templating systems such as yasnippets. One of these might be what you are looking for.
When we're using ctags in vim and want to go to particular definition of variable or function we press ctrl + ], when we want to go back we press ctrl + T.
When we want to autocomplete a name of a variable we press ctrl + N and from a little violet window we can choose the right word.
Is it possible to improve go to definition so that we won't jump in the document, but only the little window with the function or variable definition will appear?
thank you
You want a way to see the function's signature without actually jumping to its definition?
I know about two plugins supposed to provide exactly this feature:
EchoFunc,
Tag Signature Balloons
The last time I tried echofunc it didn't work for JavaScript, at least for me, but it worked well for the few PHP files I've tested it with. I didn't try the other one because it's GVim-only and I use the CLI version almost as often as the GUI version.
But you can also use TagList and/or TagBar: two very useful plugins providing great code navigation based on ctags. Both will display the signature of the tag under your cursor if you hit <Space>.
I really like the Ctrl+1 shortcut (hints for errors and mini refactorings) in Eclipse. Is there an equivalent for it in IntelliJ and Android Studio?
Alt+Enter
Personally I don't think AltEnter is particularly correct. Ctrl1 does lots of code generation like generating local variables given a method call etc.
CtrlAltV ... generates a local variable
CtrlAltF ... generate a field
AltInsert ... generate (drop down menu to generate all sorts)
Now, unrelated to the question but maybe helpful and in the same ball park is that the "foreach" short cut in IntelliJ is iter rather than for.
I also don't think ctrl+enter is the answer.
I'd say ctrl+alt+shift+t (Refactor this...) which I remapped to ctrl+1 is the closest thing to ctrl+1 from eclipse. It allows you to inline, extract code (variable, method, field etc.), move code, pull members etc.
Ctrl + 1 was one of my favorite shortcuts but unfortunately there is no exact equivalent shortcut for that. You can search for Quick fix in: File-->Settings-->Keymap, but you'll find nothing.
Although many people would say Alt + Enter is the nearest answer. but I think there are better equivalents such as Ctrl+Alt+Shift+t. It will give you some magic options.
You can also remap it to Ctrl + 1 by going to:
File-->Settings-->Keymap
Try pressing CTRL + ALT + v.
It will give the return type exactly of that method.
I think the "Other -> Show Context Actions" is very close to Ctrl+1 in Eclipse.
I know there is a trick that when you type quickly code in Eclipse, you can hit some secret keys and it will auto-complete the missing parts. Who knows them?
example: I have someVeryLongVariablesWhichIWantToTypeFast and I start typing someVeryLongVa but nothing happens. Only when I type method names a yellow box appears that wants to help me.
Ctrl + Space is the autocomplete shortcut
All shortcuts you can find under Window -> Preferences -> General -> Keys
As mentioned the command is Ctrl+Space to auto complete.
You can speed it up using camelCase...so in your example:
someVeryLongVariablesWhichIWantToTypeFast
you could start typing sVL then Ctrl+Space should auto complete or list all variables that match.
CamelCase also works for specify classes, searching for classes etc.
Others I like/use:
type sysCtrl+Space to get System.out.println statement (or err)
type foreCtrl+Space after an array/list line to foreach it
Click on an argument to a method and Ctrl+1 to create a field for it and assign it, great for constructors
Ctrl+1 on any local variable to convert to field, split declaration, or inline it
if you have
object.method().method2().method3()
selecting object.method() and type Ctrl+1 to assign to a field or local variable, then you get
Object objLocal=object.method()
objLocal.method2().method3()
//Can now select objLocal.method2() and do the same again
My favourites:
Ctrl + Space - auto complete
Ctrl + 1 - show quick fix options when you are over an error / warning
Shift + Ctrl + L - list short cuts
One trick that I love in Eclipse for Java is writing backwards (meaning you write the client before the code it calls). We typically think of autocomplete to help us with methods and variables that already exist. This is okay, but even cooler is when a method/class does not exist.
Try typing this code into a method (anywhere, really):
Who who = new Who();
who.whatUpMan("hi", 32);
Now left-click on the Who at the beginning. It will give you the choice to create a class, interface, enum, etc.
Now left-click on the whatUpMan. It will prompt you to create the method with the right parameter types and everything.
These are called "Quick Fixes" in Eclipse and they give you total freedom to code from the client "backwards" to classes it utilizes. And when you've already got the method, of course, control-space and control-shift-space (to see parameters for methods) are your friends.

Some more time savers that don't seem to be mentioned:
Ctrl+3 'Quick Access' which basically let's you reach anything without clicking around too much. E.g. type 'nav' in the popup dialog, rather than Window | Show View | General | Navigator or wherever it is.
Ctrl+O 'Quick Outline': when editing Java (and some other things), pops up a lighweight dialog so that you find anything in the file by a few keystrokes
Shift+Alt+T 'Refactoring', and things below that menu - look for shortcuts there, use 'Rename', 'Move', 'Extract method', 'Change method signature' often
Alt+Up/Down move blocks of code up/down without cut/paste
Alt+Shift+Up/Down select various levels of code (expressions,statements, methods, class) easily
Ctrl+1 on the selected code offers you cool stuff eg. Extract to variable/constant/method; Split variable declaration -- see others above, or just try it on anything
Ctrl+Shift+R find any file in the workspace, similar to Ctrl+Shift+T to find types
Ctrl + Shift + O : resolve all dependances automaticall. In Java, it's a life saver as it cleans old packages and add the required one without a single line to write.
"Right click" then "refactor" : all the features are handy, but I espacially love "rename" (Ctrl + Shift + R, c.f comments) because it will apply the changes to all the project. No more tricky find / replace wit regexp to do ensure you breal nothing else :-)
"Right click" then "source" : equally useful, with a special mention to "generate getter and setter" and "implement methods"
Ctrl + D : delete a line. Kinda cool.
I kind of remember CTRL+SPACE was the shortcut for autocomplete.
Another time-saver is formatting the code automatically using Ctrl + Shift + F.

General Eclipse tips
Get rid of all the crap that you'll never use
if you do web-dev ... install the database, php, pydev, modules and plugins
install svn/cvs/git plugin
use Trac
have different code enviornments for different code types, i.e. one for python-dev, c++, and so on.
wait a few weeks to months before updating
i have about 100 premade mini scripts that i use frequently.
learn to develop your own plugins, as it's easy and fun.
For some applications, the answer is to generate the code using EMF. But the EMF learning curve is significant.
I would suggest go to Eclipse -> Preferences -> General -> Editor -> Keys and to configure your own keyboard shortcuts for all common tasks so that you can have custom keybindings that are perfect for you.
Probably this might not exactly answer your question but it is very relevant to your question title.
You can define templates in Eclipse to magically type and get a bunch of code typed for you. For instance you may type something like syso or sout to get System.out.println() in your Java code.
This can be done by following Window -> Preferences -> Java -> Editor -> Templates. You can also add a Template View, which you find at Window -> Show View -> Other -> Search for Templates.
Here is an image to clarify

Hope it is helpful to someone :)
I used to use WingIde, where in a shortcut(f4, default) which I used quite often was Goto definition, which will open the definition file, and take me to it. Is there a similar shortcut for eclipse+pydev?
For Aptana Pydev, you have "Go To Definition": F3
(Andrew Falanga comments below that Alt+← allows you to return to the point you left)
The 'go to definition' actions enables you to get to a given definition.
It works well on 'self' tokens
It can work on methods / attributes from parameters (as the image below shows).
As others answered, F3 is the way to go, but going a bit further, you might also want to take a look at ctrl+shift+t to browse all the tokens available and ctrl+shift+r to browse all the files.
Assuming you mean "go to where a method/class/variable" is defined, in Eclipse, it is F3
Although the question is pretty time-barred, maybe this more general approach will help others looking for specific short-cuts in eclipse.
Help - Key Assist... opens a list of all available short-cuts, alphabetically sorted by description. ("Open Declaration" was the one looked for here.)
Window - Preferences - General - Keys lets you edit the short-cuts.
Actually it does not work when you set MSVC scheme. In eclipse mars go to
Windows->preferences then go to General->keys (or in type filter text type keys) then in Keys in type filter text type definition. Then you shall see in command below Python Go To Definition. In Binding text edit you can then set any shortcut you want.
