Wrapping Long Lines in Ruby for Display in Source Files
While working on a gem, I needed to generate ruby classes on the fly. Yeah, I know this should never be the case, unless I needed around 600+ classes (I was converting schema.org schemas to ruby classes).
Now, this required me to add descriptive text inside these classes, but the text was very long and I hated how the text overflowed the screen. I use vim, which promptly highlights the 80-char column marker on my source files, and I wanted this text to stick to that. Effectively, I wanted something like the following:
1 2 3 4 5 6
I knew that Rails provided a nearly similar method with the name
and I tweaked it a bit to this:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
The last method, i.e.
indent_with_wrap is what I am interested in, really.
Now, this might not be the best implementation for what I want, but it works and
is self-explanatory to me.
So, now, I can create my ERB template like this to get the desired results:
1 2 3 4 5
This makes me a happy panda :)
