How do I autoindent in Netbeans?
提问by Elazar Leibovich
In eclipse you can click Ctrl+Iat any line, and it'll automatically indent the line or group of lines according to the indentation scheme you chose in the settings.
在 Eclipse 中，您可以在任意行单击Ctrl+ I，它会根据您在设置中选择的缩进方案自动缩进一行或一组行。
I'm really missing this feature in Netbeans. Is there any equivalent feature?
我真的很想念 Netbeans 中的这个功能。有没有等效的功能？
I'm aware of Alt+Shift+Fbut it's not good enough. I want to indent a group of lines, and not all the file.
我所知道的Alt+ Shift+ F，但它不够好。我想缩进一组行，而不是所有文件。

Open Tools-> Options-> Keymap, then look for the action called "Re-indent current line or selection" and set whatever shortcut you want.
打开 Tools-> Options-> Keymap，然后查找名为“重新缩进当前行或选择”的操作并设置您想要的任何快捷方式。

Select the lines you want to reformat (indenting), thenhit Alt+Shift+F. Only the selected lines will be reformatted.
选择要重新格式化（缩进）的行，然后按 Alt+Shift+F。只有选定的行会被重新格式化。

I have netbeans 6.9.1 open right now and ALT+SHIFT+F indents only the lines you have selected.
我现在打开了 netbeans 6.9.1，ALT+SHIFT+F 只缩进您选择的行。
If no lines are selected then it will indent the whole document you are in.
如果未选择任何行，则它将缩进您所在的整个文档。
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.
一种可能的意外行为是，如果您只选择了 1 行，则必须完全选择它，否则什么都不做。但是您不必完全选择组的最后一行或第一行。
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...
我希望它只通过选择前几个字符来缩进一行，但没有用，是的，我知道我很懒惰......

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:
如果您想像 Emacs 在 TAB 上那样自动缩进，即缩进当前行并将光标移动到第一个非空白字符，请执行以下操作：
- 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
- 转到工具 -> 选项 -> 编辑器 -> 宏
- 创建一个新宏并将其命名为“tabindent”
插入以下宏代码：
reindent-line caret-line-first-column caret-begin-line
单击“设置快捷方式”并按 TAB

Pressing Alt+Shift+Findents your selection. If nothing's selected, it indents the whole file.
按Alt+ Shift+F缩进您的选择。如果未选择任何内容，则会缩进整个文件。
In newer versions of NetBeans, you can even format multiple files/folders at a time! In the Projectswindow/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.
在较新版本的 NetBeans 中，您甚至可以一次格式化多个文件/文件夹！在Projects窗口/边栏中，如果您选择一个或多个文件夹或文件并按Alt+ Shift+ F。NetBeans 询问“递归格式化选定的文件和文件夹？”，然后按 OK 将递归格式化所有选定的文件/文件夹。
On Mac OS X, shortcut is Ctrl+Shift+F. (note: it's Ctrland not ?)
在 Mac OS X 上，快捷方式是Ctrl+ Shift+ F。（注意：是Ctrl和不是?）
I've used above shortcuts on NetBeans 7 and 8.
我在 NetBeans 7 和 8 上使用了上述快捷方式。

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.
要在 NetBeans 中格式化所有代码，请按 Alt + Shift + F。如果要缩进行，请选择行并按 Alt + Shift + 右箭头键，要取消缩进，请按 Alt + Shift + 左箭头键。

for Java NetBeans 7.1 and later, even in NetBeans 8.0 (That i′m currently using) and later, the shortcut is:
对于 Java NetBeans 7.1 及更高版本，即使在 NetBeans 8.0（我目前使用的）及更高版本中，快捷方式是：
Alt+Shift+F
Alt+ Shift+F
if you look into the KeyMapaccessing from the menu: Tools-> Options-> Keymap, the "action" is Formatdefined with the Shortcut : Alt+Shift+F
如果你看看KeyMap从菜单中访问：Tools- > Options- > Keymap，“动作”是格式与快捷键定义：Alt+ Shift+F

Here's the complete procedure to auto-indent a file with Netbeans 8.
