Installation:

  1. Ensure IDLE is closed
  2. Open your .idlerc file, usually in your home directory
  3. Paste in the settings and save
  4. Open IDLE, Options -> Configure
  5. Under the Highlighting tab, Obsidian should now be a custom theme available in the dropdown list.

On Ubuntu you need to go into the .idlerc folder and edit 2 files
config-main.cfg
Add the following,
[Theme]
default = 0
name = Obsidian

In, config-highlight.cfg, copy and paste the code above.

You will probably need to create both of those files, and it may be better to go in to Options -> configure and save the default one so it generates the files itself, then edit them to add in the above theme.

On Windows, you will want to create/edit %userprofile%.idlerc\config-highlight.cfg then proceed with steps 3 - 5.

Python 3.3.3 on Win8.1

The .idlerc folder was located here C:\SPB_Data\

windows 8
C:\Users

This is a nice theme.
With WinPython (or any portable python setup) the .idlerc is in [your-python-folder]\settings\.idlerc.

This is perfect! Thanks :)

Windows 7, search for the file \Python34\Lib\idlelib\config-highlight.def, open it, paste the "texto from above" and save it.

  1. Open "python idle",
  2. go to "options" tab,
  3. choose "Configure IDLE",
  4. choose "Highlighting" tab,
  5. choose "a Custom Theme" on "Highlighting Theme" frame,
  6. choose the theme "Obsidian" (or theme name that you insert on the file)

Wow. This is amazing, thanks!

Thanks dsosby and duphenix! It worked!

In Windows 10 Professional 64 bit architecture Python3.4.x is under the following path:
C:\Python34\Lib\idlelib\config-highlight.def

Thank you for this amazing theme! ;-)

Nice one! looking good.

My eyeballs thank you kindly.

Great stuff.

ozhuang commented Nov 28, 2015

For Python 3.5.0 in Windows 10,
C:\Users\AppData\Local\Programs\Python\Python35-32\Lib\idlelib\config-highlight.def

Thank you!

coderjxh commented Mar 4, 2016

It's Perfect! Thank you o(^▽^)o

In my pc, configure file is in(Python 3.5.1 x64 in Windows 7) :
C:\Users.idlerc

Very nice. Any idea how to let decorators like @classmethod have a different color?

avmak commented Mar 23, 2016

Thank you!

I don't see the .idlerc file. :(

Is there anyway to change the font?

vamshise commented Aug 8, 2016

Very nice theme. Thanks a lot.
On windows 10, using Pythin 3.4, I had to update "C:\Python34\Lib\idlelib\config-highlight.def" file.

DanJ210 commented Aug 20, 2016

Ty for the theme and help with Windows 10. Using Python 3.5. This theme has lasted some years!

Thanks I've forked because I like the colours but prefer a perfectly black background instead of the greyish one in this theme.

It works. Thank you!

So nice, thanks boss!

Ever since installing Idle3 I can not use the "options / configure" menu item - the program freezes and a bunch of errors on the command line. Don't know what to do - everything else works, Idle3 a great editor for Python3.5 [Linux Fedora 24 64bit]. But I guess I just gotta stay with the default white look ...:(

Great theme, thanks!

Thank you! Continues to be useful. Am on Windows 10, but used duphenix's method (Sep 28, 2012 comment). Saved one of the existing themes as a custom theme, so the config-highlight.cfg was auto-created, then pasted the Obsidian data in it.
On Windows 10, the .idlerc folder was in my user folder.

Thankyou this is amazing!

Eye-saving theme, thank you!

As above, on Windows 10 my config-highlight.def file was found at C:\WinPython\python-3.6.1.amd64\Lib\idlelib and I was able to paste the Obsidian theme in there.

Thankyou this is amazing! (x2)
