In eclipse you can click Ctrl+I at any line, and it'll automatically indent the line or group of lines according to the indentation scheme you chose in the settings.
I'm really missing this feature in Netbeans. Is there any equivalent feature?
I'm aware of Alt+Shift+F but it's not good enough. I want to indent a group of lines, and not all the file.
Open Tools -> Options -> Keymap, then look for the action called "Re-indent current line or selection" and set whatever shortcut you want.
Pressing Alt+Shift+F indents your selection. If nothing's selected, it indents the whole file.
In newer versions of NetBeans, you can even format multiple files/folders at a time! In the Projects window/sidebar, if you select one or more folders or files and press Alt+Shift+F. NetBeans asks "Recursively format selected files and folders?" and pressing OK will recursively format all the selected files/folders.
On Mac OS X, shortcut is Ctrl+Shift+F. (note: it's Ctrl and not ⌘)
I've used above shortcuts on NetBeans 7 and 8.
Shift + Alt + F indents the whole file.
Select the lines you want to reformat (indenting), then hit Alt+Shift+F. Only the selected lines will be reformatted.
Ctrl+Shift+F will do a format of all the code in the page.
If you want auto-indent just like Emacs does it on TAB, i.e. indent the current line and move the cursor to the first non-whitespace character, do this:
- Go to Tools -> Options -> Editor -> Macros
- Create a new macro and call it something like "tabindent"
Insert the following macro code:
reindent-line caret-line-first-column caret-begin-line
Click "Set Shortcut" and press TAB
Here's the complete procedure to auto-indent a file with Netbeans 8.
First step is to go to Tools -> Options and click on Editor button and Formatting tab as it is shown on the following image.
When you have set your formatting options, click the Apply button and OK. Note that my example is with C++ language, but this also apply for Java as well.
The second step is to CTRL + A on the file where you want to apply your new formatting setting. Then, ALT + SHIFT + F or click on the menu Source -> Format.
Hope this will help.
I have netbeans 6.9.1 open right now and ALT+SHIFT+F indents only the lines you have selected.
If no lines are selected then it will indent the whole document you are in.
1 possibly unintended behavior is that if you have selected ONLY 1 line, it must be selected completely, otherwise it does nothing. But you don't have to completely select the last line of a group nor the first.
I expected it to indent only one line by just selecting the first couple of chars but didn't work, yea i know i am lazy as hell...
To format all the code in NetBeans, press Alt + Shift + F. If you want to indent lines, select the lines and press Alt + Shift + right arrow key, and to unindent, press Alt + Shift + left arrow key.
for Java NetBeans 7.1 and later, even in NetBeans 8.0 (That i´m currently using) and later, the shortcut is:
Alt+Shift+F
if you look into the KeyMap accessing from the menu: Tools -> Options -> Keymap, the "action" is Format defined with the Shortcut : Alt+Shift+F
