Re: [yast-devel] What about comments for YCP to Ruby conversion?

Hello,

the comments are one of the tasks, which is currently being worked on.
So you re right, we intend to translate the comments as well.
...
Of course, comments are essential part of the code so we switch to ruby
only after this is solved. This is a blocker for us.

Then I also appreciate your switch from YCP to Ruby very much!

I look forward to having openSUSE 13.1 (and then also SLE12) without YCP!


Yes, Josef is working on it, the problem is that the YCP parser does not
care about comments and throws them away. The major problem is how to bind the
comments properly with the code, you need to know the context around the comment
to decide correctly and that's a problem during parsing (you do not know what
will be the next node until it's actually parsed...)

I am a total layman regarding such issues nevertheless I dare
to make a comment:

What about changing YCP comments into actual YCP code (e.g. change
YCP comments into YCP strings using special string variable names)
so that it becomes translated into actual Ruby code (e.g. into Ruby strings)
and then change the Ruby strings with those special string variable names
back to Ruby comments?

I assume this might result a quoting hell when YCP comments
contain YCP code (e.g. YCP code that is commented out).
