I'm trying to get gedit to auto-indent my code. The auto-indent check-box in preferences doesn't work. Is there a way to get gedit to auto-indent code? (By the way, I only really care about C++ indentation. I don't need indentation for any other language.)

  • What do you mean by "autoindent"? The option from gedit does this: when you type a indented line (by pressing tab, or with some spaces) and press Enter, the new line will have the same indentation of the previous one. Dos it not work this way? If this works, what do you expect? – brandizzi Nov 23 '11 at 18:00
  • I ment like an IDE where it will automatically insert a tab between brackets. Although that, which I did not know about, sounds fine. Thanks! – Linuxios Nov 24 '11 at 17:55

    Ah, now I understand, it so something more like Eclipse and other IDEs... AFAIk gedit does not do it neither any plugin provides such functionality. It seems to be feasible through a plugin, however, so you _may_ look for such plugin eventually. – brandizzi Nov 24 '11 at 18:45
  • Hm. O well. I still prefer gedit to IDEs right now. Every IDE I find is java based, and java and my system aren't good friends--to say the least. Its slow and buggy on my Ubuntu. I've started using gedit for all my coding, from ruby to C++. Maybe I need to go back to an IDE? – Linuxios Nov 25 '11 at 15:40

gedit has an auto indentation feature, go to

Edit -> Preferences -> Editor -> 3rd line

The plugin 'intelligent text completion' for gedit does exactly what you describe: https://github.com/nymanjens/gedit-intelligent-text-completion

For those who are trying to find out how to copy the files intelligent_text_completion.plugin and intelligent_text_completion.py to.local/share/gedit/plugins, please do the following:

user@example:~/.local/share$ cd ~/.local/share/
user@example:~/.local/share$ mkdir gedit
user@example:~/.local/share$ cd gedit/
user@example:~/.local/share/gedit$ mkdir plugins
user@example:~$ cp intelligent_text_completion.plugin intelligent_text_completion.py ~/.local/share/gedit/plugins/

    using this plugin I get an error next time starting gedit3: ERROR:/build/buildd/pygobject-3.4.0/gi/_gobject/pygobject.c:946:pygobject_new_full: assertion failed: (tp != NULL) Aborted – Karl Adler Apr 18 '13 at 14:27
  • I have heard these kind of erorrs before, but I can't seem to reproduce them on my system. If you would find the solution, please let me know. – Jens Nyman Apr 19 '13 at 06:50
  • The code has moved to github: https://github.com/nymanjens/gedit-intelligent-text-completion – nephiw Jul 04 '16 at 20:36

Here is another workaround, you can use vim to auto indent and auto format your code from inside Gedit.

First make sure that vim is installed. Next, add an "external tool" to Gedit from the "tools" menu and use the following code:

#!/bin/sh
CMD_FILE_NAME=.formatcommand;
TMP_FILE_NAME=.tempvimfile;
touch $CMD_FILE_NAME&&echo "gg=G :wq! "$TMP_FILE_NAME > $CMD_FILE_NAME&&(vim $GEDIT_CURRENT_DOCUMENT_NAME -s $CMD_FILE_NAME > /dev/null 2>/dev/null)&&rm $CMD_FILE_NAME;
cat $TMP_FILE_NAME
rm $TMP_FILE_NAME

Also make sure that:

  • "Save" is set to "Current document".
  • "Input" is set to "Nothing".
  • "Output" is set to "Replace current document".

You can also setup a hotkey, I prefer Alt+Shift+F like Netbeans. Now whenever you press the hotkey, the current file will be saved and auto formatted.

This will work on any programming/scripting language given that the file's extension is correct

If you don't get the indentation put filetype indent on in your ~/.vimrc file and it will work.

  • That's awesome! Thanks! Good timing, because I just started using vim to do the editing itself :) – Linuxios Jun 07 '12 at 14:04
  • Great :) I wrote this in a hurry so the script might not seem very elegant but it just works ! – Hussein El Motayam Jun 07 '12 at 14:15

    Hey @HusseinElMotayam I just tried your workaround and its giving me these errors: Running tool: Format Vim: Warning: Output is not to a terminal Vim: Warning: Input is not from a terminal cat: .tempvimfile: No such file or directory rm: cannot remove `.tempvimfile': No such file or directory Exited: 256 – Etienne Lawlor Nov 09 '12 at 23:36
  • @HusseinElMotayam You are my hero! ;) I'll edit your post a bit to fix some minor problems. – naugtur Jan 28 '13 at 19:15
  • I want to love this, but it breaks python code by indenting lines that shouldn't be indented. – Amanda Feb 11 '14 at 22:09

Ubuntu 16.04 and Gedit

    Edit → Preferences → Plugins → External Tools
