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?

Thank you!

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

Is there anyway to change the font?

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.

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)

Brilliant, just what I was looking for, thankyou

beautiful them , Thanks a lot.

<On Windows 7, Python 3.6> I couldn't save "config-highlight.def" file after editing it in the "\Python34\Lib\idlelib" folder, So i had to move the file "config-highlight.def" to "C:\Users\User.idlerc" folder, then i edited it and saved the file in "C:\Users\User.idlerc" folder, after that i returned the file in "\Python34\Lib\idlelib" folder, I've struggled so much but finally it worked.

As listed above, For Python 3.6.4 x64 in Windows 10:

C:\Users\AppData\Local\Programs\Python\Python36\Lib\idlelib\config-highlight.def, then add the code to the end of the file.

Ensure IDLE is closed first, then edit the file and save then close. Then open IDLE and navigate to Options > Configure IDLE > and select the "Hightlighting Theme" button underneath a Built-in Theme (unless you are already using 'a Custom Theme); by default it will read, "IDLE Classic" so click it and select "Obsidian" from the drop-down menu. If you want it to fit in nicely, you can open the config-highlight.def file and change [Obsidian] to [OBSIDAN].

Thanks to everyone in the comments above that made this doable using the latest software on the latest build of Windows 10 and for the OP for such an awesome schema I didn't have to manually customize myself.

Cheers,

Cant find the file location on Mac... send help!

This is great!

Cant find the file location on Mac... send help!

Bring Spotlight search (command AND space) and search for idlelib
if you have downloaded using anaconda, it should be under anacondaX > lib > python3X > idlelib

HAHA THANKS BRO

:)

MARAMING SALAMAT :)

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! ;-)

In Windows 10, 64 bit architecture, using Python 3.8 (also 64 bit) it seems to be located at:

• C:\Program Files\Python38\Lib\idlelib\config-highlight.def

I have made a video on steps of how to set Obsidian (or in general any theme) in IDLE for Windows 10 platform. Real thing starts from 0.50min. https://www.youtube.com/watch?v=xV4tndJX_wI

This is very helpful, thank you for taking the time to make, share and teach how to install it. I'm sure plenty of people are fine with the defaults, but for me at least I prefer something like a Nightmode every time. It's the difference between reading happily and reading with a flashlight in my face. Best wishes.

Oh Thanks Man, You saved my eyes....

You cab use this for black theme. better for me.

Thank You 💯

I have a nice edition of myself. You guys can check it out. Ty <3
