Add color schemes to IPython console

[spyder-bot]

From [email protected] on 2012-01-22T23:45:51Z

I wonder if Spyder can provide color scheme options for the IPython windows (as well as the Console windows)... I use black background on the main editor and the object inspector. And the white background of IPython and Console looks a bit annoying... Attached is how it looks on my computer.

Hi,

It's not possible to define a color scheme for the IPython console but you can go to

Tools > Preferences > Console > Display

and look for the section called "Background color". In there deselect the option called

"Light background (white color)"

and next time you open a new console, you'll see it has a dark background with a predefined color scheme

Seconded. IPython follows the colour scheme of the separate terminal I use (Console2 on Windows), but it does not follow Spyder's colour scheme. I would not call it a defect, though, but an enhancement request.

Ipython's qtconsole uses pygments for syntax highlighting. Perhaps spyder could convert its color scheme to pygments when embedding the ipython qtconsole.

Yes, this is now possible but only for IPython. We'll try to add it for 2.2.

I'd be interested in this as well. Any update on the Ipython color schemes, or at least a dark backgorund? Also, looks like issue #1520 should be merged into here...
Cheers!

I have done it and contributing to spyder! Too bad it seems that google-code remove serverside cloning (Forking) so i have to attach a patch.

It will automatically try to match with current background and foreground color set in your code background.

patch attached , pasting here looks ugly.
Spyder guys , don't you want to move this awesome project from shitty google-code hosting? Google no longer cares about googlecode anymore , time to move to Bitbucket I know you guys love mercurial like the rest of python devs. Github is awesome but we love HG!

Thanks a lot phyo for the patch! You are proposing something much more ambitious just using a dark background, it's meant to use our own color schemes. That requires more work and that's why I'm leaving it for 2.3.

I didn't notice GoogleCode eliminated the option to do server-side clones. It's really time to move to BitBucket, you're absolutely right! I'll try to do it in the next couple of weeks.

You welcome ccordoba12!

Yep , my patch does it. It reads the config of currently active color schema and applies it to ipython directly.

I didn't notice GoogleCode eliminated the option to do server-side clones.
Yeah man , i was looking for any kind of announcement of the removal but i found none. Damn , what happened to our respected tech giant..

I am working onwards automatic coloring of ipython , including ipython's syntax.
I am stuck how to apply CSS scheme for ipython console syntax coloring, attached is the code.

Pull request submitted.

[goanpeca]

@v3ss0n?

[ccordoba12]

He implemented this feature on Bitbucket, but his pull request was a bit messy. We'd need to port it here.

I pretend to do that for beta2.

[goanpeca]

👍

[goanpeca]

What is the plan?

To keep the global Coloring Scheme and for all Consoles (ipython included) add the option to select the coloring scheme with a checkbox, to use the same as the editor? (to avoid repetition?)

[goanpeca]

Just adding comments to include the bitbucket code

https://bitbucket.org/spyder-ide/spyderlib/pull-requests/19/finally-working-adaptable-ipython-color/diff

@ccordoba12 is this something that cannot be done until you finish your kernel and stuff work, or is this something that can be done in parallel?
