New feature: whitespace colour

[yvesdm3000]

I added a feature to CB to alter the colour of whitespace.

I think this should be base functionality, no idea if it can be implemented as a plugin or if it's worth it to do so...

Can you show a screenshot depicting the use case for this feature?
I'm not sure I understand why someone will choose different colour than the background colour in the syntax highlight.

About this topic, some program like Notepad++ can show the "white space" and "tab" as a special characters(dot and arrow), see image shot below, which I though is a quite nice feature.



EDIT: it looks like C::B already has this feature.

ollydbg : Good news,  Code::Blocks can do this allready !

But with latest SVN version, you can't alter it's colour, it simply uses the normal text colour and I find that a bit too intrusive.

In this screenshot, I altered the default to use a light grey. You hardly notice it unless you need it, which is way better than the black it had before. About any other editor that I know of and tried can do this, and once you get used to a feature and you change apps, you start to miss it...

A lot of other editors and Scintilla also allows you to set the whitespace background color and the size of the dot, but I don't really see the use for these extra features so I didn't add them (although it would be very easy to add them)

So this allows changing the colour of the white space special character when they are shown?

BTW: The screen shot doesn't show.

That's correct.

BTW: I updated the image with a better one.

I like the idea. I wouldn't mind if this gets applied. I'll give it a try...

yvesdm3000: Can you give us rgb values for the color you're using in the screen shot.

[yvesdm3000]

Does it matter what colour? The patch I've sent in gives you the choice to select the color and I honestly didn't give that much attention selecting any exact colour, the color I took might even be a little bit too bright.
In any case, if you intend to hardcode it, be aware that a lot of people have black backgrounds and will therefore need another colour (or shade of grey or any other colour like red as in the screenshot from Notepad++)

The colour that I seemed to have picked is #D2D2D2 (R=G=B=210 or H=0, S=0, V=82)

The attached screenshot shows how it's configured.

No, I don't want to hard code it, but I don't think black is a good default value.

[yvesdm3000]

Oh, I chose black because that was the colour it was before...

In svn, a bit modified, thank you.
