I want to know if there is a way to highlight the full content in an expression like if, while, etc.
I have to work in a code that is bad indented where expressions can cover over 1000 lines and I can't format it.
for exemple :
if ($somethingTrue) {
while ($somethingHappen) {
// 500 lines...
} }
if ($someCondition) {
}
look, it's very hard to see the end of the first if and what it cover...
Does someone know if there is a native feature or plugin on netbeans that do this job ?
Thanks !
You don't need any plugin/external jar file for achieving the same. Whichever expression you want to check the body of, just click on the opening brace after that expression and NetBeans will automatically show you the closing brace for that expression.
Basically, Netbeans shows the ending brace for a corresponding starting brace entry---for each of if-statements,loop-statements,method declarations,etc.
In the shown figure, see my if-statement starting with yellow brace(cursor blinking there), and the corresponding ending brace for the if-statement.
EDIT :-
You also can also have a brand new-code fold,just by typing fcom, and hitting (Tab) button on KeyBoard. And, then put whatever block you want inside it and done. Expand whenever you wish and collapse whenever you want.
Check the position of my mouse-pointer which shows the current block of if-statement. You can expand and collapse as per your wish. And, also you can have several of them for each of your expression-tree.

When I select a block of code in VS Code I get the following:
png
At the end of each line, and at the beginning of the selection, the editor selects an extra space (that isn't actually there). How can I stop it from doing this? I want the selection to be exactly the text that I select and nothing else.
So, let's say I select a closing brace. I want eclipse to not only highlight the matching opening brace, I want it to show me its whole line on the top of my editor, no matter how higher up it is. I'm sure I've seen it on some other IDE, is it possible to do on Eclipse? For example, if it's a closing brace for an if statement, I want to see the opening of this if to see its condition. This could also apply to methods, loops, etc.
If not showing the whole line, I would at least like to highlight the whole line with a color that stands out, so that I can find it easier through scrolling. I know I can jump there with Ctrl+Shift+P, but it's not always practical.
When using "change all occurences" in VS Code, it will just search the whole file for matches and change them. Is there a similar feature doing the same thing, but limiting it to function or block scope?
Let's take an example where I would need that: I'm having a React file with several components and want to refactor a class component to a functional component, so I'm changing all occurences of this.props to props. However, I obviously don't want to change all the other class components as well that are supposed to stay class components. :-)
This seems like such a standard use case, but I'm not able to find it anywhere in VS Code. If it's not possible (yet, or for some good reasons) is there another way to achieve what I'm trying to do?
Check out the 'Add Selection To Next Find Match' functionality. It allows you to highlight the first occurrence you'd like to change, then using a keyboard shortcut, highlight the next occurrence and so on until you've selected all the instances you want to change. When all to-be-changed occurrences are selected, you can edit the selected text normally. Just remember to hit the escape key a couple times after editing to return to a single cursor!
Here are the keybindings for the command, it's Cmd+d on Mac:
https://code.visualstudio.com/docs/getstarted/keybindings
I find it very useful when renaming variables, there's also a shortcut to skip occurrences (Cmd+k Cmd+d) in case there is text you don't want to change in between.
I'm trying to use the multi cursor functionality of vscode on a large(ish) file.
the file is too large to select every line individually with ctrl-alt-up or down. In sublime-text I would select everything and push ctrl-shift-l. Is there a similar thing in vscode. I've tried using a regex search for ^, but that gives me an error stating "Expression matches everything".
The command Selection / Add Cursors to Line Ends altshifti will put a cursor on every line in the current selection. (For mac use optshifti)
Tip: You can pull up the keyboard shortcut reference sheet with ctrlk,ctrls (as in, those two keyboard combos in sequence).
(For mac use cmdk,cmds)
Hold Alt+Shift and select the block. Then press End or Right button.
You get selected individual lines.
I use version VSCode 1.5.3 in Windows.
Hold Alt+Shift+i
Hold Home (fn+-> Mac) for right-most or End for left most(fn+<- Mac)
This feature is actually called split selection into lines in many editors.
Sublime Text uses the default keybinding, CTRLSHIFT L
VSCode uses ALTSHIFTI
For Atom you actually need to edit your keymap to something like this
'.platform-win32 .editor, .platform-linux .editor':
'ctrl-shift-L': 'editor:split-selections-into-lines'
Real Lines vs Display Lines
First we have to understand the difference between Real Lines and Display Lines to completely understand the answer of the question.
When Word Wrap is enabled, each line of text that exceeds the width of the window will display as wrapped. As a result, a single line in the file may be represented by multiple lines on the display.
The easiest way to tell the difference between Real Lines and Display Lines is by looking at the line number in the left margin of the text editor. Lines that begin with a number correspond to the real lines, which may span one or more display lines. Each time a line is wrapped to fit inside the window, it begins without a line number.
Cursor At the Beginning of each Display Lines:
Cursor At the Beginning of each Real Lines:
Answer to the Question
Now that we know the difference between Display Lines and Real Lines, we can now properly answer the actual question.
Hold AltShift and select the text block.
Press Home to put cursor on the beginning of every Display Line.
Press End to put cursor on the end of every Display Line.
Press HomeHome (Home twice) to put cursor on the beginning of every Real Line.
Press EndEnd (End twice) to put cursor on the end of every Real Line.
Please understand that AltShiftI put cursor on the end of every Real Line.
Install the extension Sublime Commands.
[Sublime Commands] Adds commands from Sublime Text to VS Code: Transpose, Expand Selection to Line, Split into Lines, Join Lines.
(Don't forget to add the keybinding(s) from the extensions details page to your keybindings.json)
Doesn't VS Code already have a "split into lines" command?
Yes, yes it does. However it differs from the one in Sublime.
In VS Code, when you split into lines your selection gets deselected and a cursor appears at the end of each line that was selected (except for the last line where the cursor appears at the end of the selection).
In Sublime, when you split into lines a cursor appears at the end of each line (with the same exception as in VS Code) and the selection is divided on each line and "given" to the same line.
I have the same problem, i'm used to Alt + drag to do 'box selections' in visual studio but it does'n work in code.
It seems to be impossible for now to do it differently than by selecting every single line.
However plugins should be supported soon so we will likely see a plugin for this if not implemented directly by microsoft.
From visual studio uservoice forums:
We plan to offer plugin support for Visual Studio Code. Thank you for your interests and look for more details in our blog in the coming weeks. http://blogs.msdn.com/b/vscode.
For the preview we are looking for exactly this type of feedback. Keep it coming.

In Eclipse, I can format comments by selecting them and pressing Shift + Ctrl + F. For example, when I select a method comment like this:
/**
* This method
* does some stuff.
*/
and press Shift + Ctrl + F, Eclipse automatically wraps it:
/**
* This method does some stuff.
*/
Is there anything comparable to this in IDEA?
EDIT: To clarify, I'm looking for comment formatting that also breaks lines that are too long into multiple lines.
The closest thing that you can get is Edit | Join Lines (Ctrl+Shift+J). You have to select the lines you want to join first.
To wrap long comments enable Settings | Code Style | JavaDoc | Wrap at right margin.
For Javadoc comments, you want to make sure the "Wrap at right margin" setting is checked. See Code Style > JavaDoc, under "Other". However, this setting only seems to take effect when you reformat the whole file, since a reformat of just the Javadoc (i.e., select the Javadoc, then do a Code (menu) > Reformat Code... or CtrlAltL) that exceeds the right margin doesn't force it to wrap. If I reformat the entire file, then it wraps at the margin as expected.
This seems like a bug (though one that doesn't seem to have been reported), since if you have to set the "Ensure right margin is not exceeded" checked, then selecting the Javadoc text and doing a reformat code does indeed wrap the lines. This setting is in Settings > Code Style > Wrapping and Braces. You can also do a search in the Settings dialog for "ensure right margin".
You'll still have to manually join the lines using CtrlShiftJ
This might be worthy of an improvement request to JetBrains.
Existing comment will be reformatted when you do "Reformat Code" (⌥⌘L in Mac).
#kghastie uncovered the key.
Steps:
Set the Code Style > Java > JavaDoc > Wrap at right margin setting.
Select the full lines of the entire JavaDoc comment.
Reformat Code (Ctrl-Alt-L or ⌥⌘L).
Lesser alternative:
Set the Code Style > Java > JavaDoc > Wrap at right margin setting and the Code Style > Java > Wrapping and Braces > Ensure right margin is not exceeded setting.
Select some text within a JavaDoc comment.
Join Lines (Ctrl-Shift-J) followed by reformat Code (Ctrl-Alt-L or ⌥⌘L).
Beware: This will leave all the selected lines joined even where you had paragraph breaks (<p/> or \n\n).
The JetBrains plugin Wrap to Column is made for this:
From the overview:
Wraps text to the specified column width. Similar to the Emacs command 'Fill Paragraph' and Vim's gq (format lines) command. This is a replacement for the native Intellij Fill Paragraph command, which doesn't work quite how I need it to.
This plugin provies two IDE actions:
Wrap Line to Column: Wraps selected text or the current line if no text is selected. This is useful for IdeaVim users who wish to pair the command with motions like vip (select current paragraph).
Wrap Paragraph to Column: Wraps the paragraph (multiple lines) in which the cursor appears. No selection is needed, and will be ignored.
I'm using IntelliJ 14 on a Mac, which has a Fill Paragraph command. Access it via the awesome universal Command-Shift-A action search feature. Works like a charm!
This is a hack, not a really good solution, but if you have a block of code that you want formatted like this and it's in serious need of auto format, because it's going over the 80 line max, or it's just unreadable...
You can just put if ("foo" == "bar") { on top of whatever you want formatted, and then and the} at the bottom of the if statement, to close it, and voila, your code should auto-indent, auto format, etc... Then take it out, highlight all of what you just formatted and press SHIFT+TAB to move it back 4 spaces and remove the dummy if statement
