Is there a way to select a C/C++ expression in Eclipse and put a bracket around it with a single keyboard shortcut? IDEs usually have this but I couldn't find a way in Eclipse.
For Java Code, there is a more or less good workaround described in Parentheses over selected words in Eclipse, but this does not work for C-Code - after bringing up the template list for the selection, the suggested templates are empty.
As far as I know, exactly that is not possible. You might report it to Eclipse CDT as a feature request.
But as workaround a template like the following can be used:
(${line_selection})${cursor}
If you hit Shift+Alt+Z the Surround With Quick Menu shows all templates containing ${line_selection} and with a number key a templated can be selected.
The key Shift+Alt+Z can be changed, but unfortunately no key can be defined to select the template directly. Also unfortunately, this does not work for multi-line selections because everything in the template in the line before ${line_selection} will be applied to each selected line.

Whenever I am working in a JSP file and I type ${ to start an el (Expression Language) tag, Eclipse will automatically add } (with a space before the closing brace) after the cursor so that I get ${ } instead of ${}.
Is there a code template in Preferences that I can modify to change this behavior, or is it beyond user preference control?
I have checked in Preferences: Web: JSP Files: Editor: Templates, but none of those templates match. I've also looked in several other sections in Preferences but haven't found anything promising.
What #Mero provided (see comments on answer above) might not be an exact answer, but creating a JSP Template probably the closest thing that I've found.
A few notes for anyone that wants to go that route:
Create a new template through menu Window->Preferences, then in the drill down menu navigate to Web->JSP Files->Editor->Templates. Click New.
Name is a shortcut you can type (the same way typing sysout ctrl+space in Java is a shortcut for System.out.println()). I suggest something simple like el. This allows you to type e l ctrl-space instead of $ { ctrl-space to pull it up.
Context tells it when it should appear in intellisense. I suggest creating two of this template where one has a context of JSP Attribute value and the other has a context of All JSP.
Description is just informative. Put whatever you want. I put 'EL Script' myself.
Pattern is where you put what will be inserted. Put $${${cursor}} or $${${script}}, depending on preference. See below for explanation on the differences.
In Eclipse Templates ${} is how you put variables in the template, so to make it actually print ${} you have to escape the $ with a $$ leading to $${}.
The predefined variable ${cursor} defines where the cursor is after intellisense replaces the el, so to have the cursor appear in between the curly braces you want to do this: $${${cursor}}.
Using any variable that is not predefined (in this case, ${script}) will simply put in that variable with a box around it and allow you to type over it and press enter when you're done, allowing you to move to the end of the closing curly brace.
Note: I understand that this is not an actual answer, but rather is a workaround. I'm putting it here simply so that those who are fine with a workaround can know how to go about doing it.
Edit
For those that don't like having to type ctrl-space, a workaround could be to have the template name start with< since on JSP pages, the < opens the intellisense, so for instance, you could have the name be <el or <$.
A workaround but not an answer:
Disable auto-close of EL tags. You type ${expression} and get ${expression}|, rather than typing ${expression and getting ${expression| }. (| denotes the cursor location)
See this answer, from when this same question was asked of Eclipse Kepler: https://stackoverflow.com/a/20258401/1021426
I'm very happy with the way eclipse autocompletes for me, but I was wondering if it could do something more...
I often have very similarly named variables, such as myPlayerManagerPane and myCharacterManagerPane, I was wondering if there was a way that would allow me to get half way into the name, type a character or two and then autocomplete. This would let me copy and past lines of code for both, then surgically edit the variable names. It's gotten to the point where I'm trying to do this (I'm autocompleting on autopilot) and getting fun variables such as myCharacterManagerPaneManagerPane as I autocomplete a whole name, halfway through another.
Is there a way around this?
In Window > Preferences > Java > Editor > Content Assist, select "Completion overwrites", instead of "Completion inserts". This would overwrite the entire variable with the new one.
Alternatively, you can press Ctrl to toggle this behaviour when the content assist window pops up.
Your question (or rather, its prelude) can easily be confused with another one; namely,
Say I have two variables variableLabel and variableConfiguration, how can I have Eclipse complete the common prefix of the two variables, i.e. variable, before writing either L or C and having Eclipse "AutoComplete" complete the rest?
This is the question which lead me to this thread, so I feel I must answer it:
In Window > Preferences > Java > Editor > Content Assist, check "Insert common prefixes automatically". Pressing Ctrl+Space now results in the desired functionality.
Relevant StackOverflow question
Today I have question about Eclipse. I use this IDE very long and I think it is good, but last time I miss for some functionalities...
Is it possible to set some shortcut which will do something like:
Mark some text ('Hello world'), trigger shortcut (Ctrl+T) and it will do something with that text - in example adds text before and after selected text ($this->_('Hello world'))
?
Thanks for any sugestion !
From this, it appears you have to implement your own command in a plugin. The process looks more involved than simply setting a menu choice.
Equivalent functionality can be defined without commands, if you're willing to give up the keyboard shortcut and use content assist instead.
I'm not sure if it will work with the language you're using (PHP?), but with Java in Eclipse it is possible to use Code Templates.
You would define your own template, when it was applicable and what it would do. This could then be accessed with Ctrl+Space through the possible content assist methods. So in the context of Java statements, I can define:
this.call(${word_selection});
So when I highlight a word, such as "Hello, world", I can use the template to change it to:
this.call("Hello, world");
(There are ways to limit it to only String types instead of word selections, but that will most likely not apply to your language, so I didn't pursue exactly how to do it.)
The Code Templates menu is available through Window->Preferences.
In CFEclipse, I do a lot of double-clicking to select text. The standard behavior is to select all text within the nearest word boundaries. This is problematic when editing code where the original editor didn't use camel-case; for example, they wrote "myObject" as "my_object".
Is there a way to change the double-click selection behavior to include '_' as a valid word character?
In the latest version of CFEclipse, there is now the option to define what characters are considered word boundaries when double-clicking, and also the option to use different characters when using alt or shift keys.
In Preferences, goto CFEclipse > Editor > Text Selection to update this:
(source: bpsite.net)
CFEclipse does not recognize either the underscore or a period as a character for selecting text with a double-click. There is no way that I know of other than rolling your sleeves up and hacking the editor code to change it. I doubt that this will be changed any time soon with the impending release of Bolt from Adobe.
On eclipse 3.4.1 Ganymede, it seems to select the nearest boundaries including the '_' (at least in the java file I am using)
What eclipse version are you using ?
This blog even reports that eclipse3.3 does select word as you are expecting it...

Is there an Eclipse command to surround the current selection with parentheses?
Creating a template is a decent workaround; it doesn't work with the "Surround With" functionality, because I want to parenthesize an expression, not an entire line, and that requires ${word_selection} rather than ${line_selection}.
Is there a way that I can bind a keyboard shortcut to this particular template? Ctrl-space Ctrl-space arrow arrow arrow isn't as slick as I'd hoped for.
Maybe not the correct answer, but at least a workaround:
define a Java template with the name "parenthesis" (or "pa") with the following :
(${word_selection})${cursor}
once the word is selected, ctrl-space + p + use the arrow keys to select the template
I used this technique for boxing primary types in JDK 1.4.2 and it saves quite a lot of typing.
Easy, Window->Prefs, then select Java->Editor->Templates
Create a new template with : (${line_selection}${cursor})
The "line_selection" means you have to select more than one line.
You can try creating another one with "word_selection", too.
Then, select text, right click, Surround With... and choose your new template.
