How can I permanently enable line numbers in IntelliJ?

How can I permanently enable line numbers in IntelliJ IDEA?

Solution 1:

IntelliJ 14.X Onwards

From version 14.0 onwards, the path to the setting dialog is slightly different, a General submenu has been added between Editor and Appearance as shown below

IntelliJ 8.1.2 - 13.X

From IntelliJ 8.1.2 onwards, this option is in File | Settings¹. Within the IDE Settings section of that dialog, you'll find it under Editor | Appearance.

1. On a Mac, these are named IntelliJ IDEA | Preferences...

Solution 2:

The question is obviously well answered already, but since IJ 13 you can enable line numbers in 2 seconds flat:

1. Press shift twice
2. Type "line number"
3. The option shows in the menu and press enter to enable/disable.

Et voila ;)

Solution 3:

NOT a solution, rather a TEMPORARY solution which only works only for the current editor and current session:

Simply right click on the place where the line-numbers should be, and there you'll see a small menu.

then, mark the "Show Line Numbers" option.

Please note that this only works on a per-file basis, however. Enjoy.
