How to get gedit to auto-indent code

Question

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.)

Answer 1

gedit has an auto indentation feature, go to

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

Answer 2

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/

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.
