Cream – Commentify

Cream Comment

No matter programming or editing latex files, “comment code” is an important feature. Cream supports comments as well, but it acts a bit weird. For example. If commenting following LaTeX paragraph.

A quick fox 
jump over 
the lazy dog.

If you mark from top to down, after commented, it looks like:

%%%%A quick fox 
%%%jump over 
%%the lazy dog.

If you mark from down to top, after commented, it looks like:

%A quick fox 
%%jump over 
%%%the lazy dog.

After some tracing, I found that some thing strange happened in EnhancedCommentify.vim:

Normally, whenever user selects Tools ->Block comment, Cream_decommentify("v") should be called exact once. However, for very strange reason, it will be called as many times as the number of lines be marked. If you have this problem, you may try my patch, which is shown as follows:
