Howto create a color-scheme for FDT

Posted on by

I’ve been wanting to be able to use a different color-scheme (or theme) for FDT for a while. After some investigation I found out how to do this.

FDT dark color scheme

I’ve created the color scheme above and stored in an epf file, you can download it here:
http://ansuz.nl/toys/fdt/eclipse_fdt_dark_01.epf (right click and save as…)

Creating the scheme

  1. Modify your preference for text appearance (see ‘Eclipse + FDT colors‘)
  2. Hit File > Export > General > Preferences and save in a convenient location
  3. Open the saved file in your favourite text editor and remove everything that’s not color related. There are a couple of exceptions to this though, see ‘Eclipse + FDT colors update‘. Others you’ll probably find out in a trial and error proces.
  4. Add ‘file_export_version=3.0’ to the top of your file, so Eclipse knows what version the preferences were exported for. (You can also not delete this line in step 3.) If you omit adding ‘file_export_version=’ the importing of the preferences will fail.
  5. Save the file and you’re done!

Importing a scheme

  1. Hit File > Import > General > Preferences
  2. Click ‘Next’.
  3. Select the scheme to import and click ‘Finish’
  4. All done!

Eclipse + FDT colors update

I figured out what was missing in my previous attempt to store and then load my color preferences. You need to include what version of Eclipse the preferences file is exported for.

file_export_version=3.0

A couple of other things include some boolean settings for not using the system background color and using the ruler (line numbers).

/instance/org.eclipse.ui.editors/AbstractTextEditor.Color.Background.SystemDefault=false
/instance/org.eclipse.ui.editors/AbstractTextEditor.Color.Background=0,0,0

Metaballs

This week I’ve been working on creating a liquid effect in Flash. After a little research and a relapse to my got old 3D days I remembered a principle called ‘Metaballs‘ or ‘Iso surfaces‘. This is a nice way to replecate fluid dynamics in a 2D or 3D environment. So after some web browsing I found a nice implementation in AS3 by Szataniol. The only problem with this implementation was that it lacked alpha, which I needed to be able to apply some filters for a more realistic effect. This was easily solved by adding an extra render pass to calculate the mask. I’ll post the code for that below.

I hooked up the ‘renderer’ from Szataniol to the Box2D physics engine and starting messing around. I ended up making a couple of different versions:

I’ve set up my Main class in such a way that I can easily switch settings to create the different effects by using a different Model class.

Eclipse + FDT colors

Posted on by

I’m trying to figure out a nice way to apply a color theme to Eclipse. So far no luck, but I have found the places where to edit color settings.

First got to Window > Preferences, then change the color settings in the following locations:

  1. General > Editors > Text Editors
  2. General >Appearance > Color and Fonts
  3. FDT > Editor > Colors
  4. FDT > Editor > Semantic Highlight

Some ideas to explore:

http://www.willianmitsuda.com/eclipse-plugins/eclipse-skins/ (Skin plug-in, see how to get this to work with FDT)

Update: Exported preferences, now trying to figure out how to strip all non color scheme related information.

Update 2: Found a doable way to create a color scheme for FDT, read the howto.
