I have found the Ruby Style Guide while I was trying to find out which case conventions the Ruby community uses for methods.

Fortunately there's a Ruby Style Guide (thanks!) and I quickly found theSnake Case for Symbols, Methods and Variables section. I didn't know by heart what "snake case" is (I always confuse the case style names and "snake" doesn't say anything to me) so I had a look at the examples.

Here a screenshot how my gaze went:

After 1, 2, 3 was a bit of uncertainness. So after a short pause (color now turquouise instead of red) I discovered 4 (grey and discreet), had to look for 5 and finally found 6, which was the answer for my question.

My suggestions are to

• write the "Good" examples before the "Bad" examples and
• maybe disable syntax highlighting for "Bad" examples (or mark them as bad somehow else which is more intuitive than the comment, which may also be above the current view).

I hope my suggestion is placed correctly here.
