Dark Theme for Processing - can't set colour of variable names.

RichardDL

I want a dark theme for Processing and there are various discussions and schemes. I've tried some, and this is what I'm doing.

Reverse the default colours in theme.txt

editor.fgcolor = #FFFFFF 
editor.bgcolor = #000010

Tweak the 16 editor colour items in preferences.txt. (Preferences.txt gets written out by processing, without comments, so I'm keeping my own master file and copying it into place before running Processing.)

Here are my test settings, everything that I've identified as being able to adjust the colour is set to 008000 (dark green). All the items that apparently change nothing are set to FFFF00 (yellow). (There may be program elements that I haven't encountered today.)

editor.token.comment1.style=#008000,plain       # comments
editor.token.comment2.style=#008000,plain   # comments
editor.token.function1.style=#008000,plain  # print, println, frameRate, background
editor.token.function2.style=#008000,plain  # size, format
editor.token.function3.style=#008000,plain  # for, if
editor.token.function4.style=#008000,bold   # draw, setup
editor.token.invalid.style=#ffff00,bold         # NOTHING?
editor.token.keyword1.style=#008000,plain       # void, true, false.
editor.token.keyword2.style=#008000,plain   # (String.)length
editor.token.keyword3.style=#008000,plain   # else
editor.token.keyword4.style=#008000,plain       # frameCount
editor.token.keyword5.style=#008000,plain       # int, String, boolean, float
editor.token.keyword6.style=#ffff00,plain       # NOTHING?
editor.token.label.style=#008000,bold               # NOTHING?
editor.token.literal1.style=#008000,plain       # "Quoted Strings"
editor.token.literal2.style=#ffff00,plain       # NOTHING?

Surprises/Questions: - Colour of 'if' and 'else' are controlled by different items. - All these use the default colour from theme.txt - variable names - operators - brackets - numeric contstants.

Looking at the example CircleCollision with above test scheme, there is too much white remaining. Would like to change the colour of those 4 types of item.

Interesting, @RichardDL. Thank you for sharing these tests.

The settings that I know about are taken from these two files:

• https://github.com/processing/processing/blob/master/build/shared/lib/defaults.txt#L242
• https://github.com/processing/processing/blob/master/app/src/processing/app/syntax/Token.java

I don't think you are missing any. For reference of people in this thread, here are the core system defaults from defaults.txt:

editor.token.function1.style = #006699,plain
editor.token.function2.style = #006699,plain
editor.token.function3.style = #669900,plain
editor.token.function4.style = #006699,bold
editor.token.keyword1.style = #33997e,plain
editor.token.keyword2.style = #33997e,plain
editor.token.keyword3.style = #669900,plain
editor.token.keyword4.style = #d94a7a,plain
editor.token.keyword5.style = #e2661a,plain
editor.token.keyword6.style = #33997e,plain
