Ignoring comment lines

Hello,

Thank you for providing a useful extension, which improves my productivity. This is related to #13. In Python world, I’m regularly working with CSV-like files containing multiple comment (header) lines as below.

# 1st comment line
# 2nd comment line
# 3rd comment line
# :
# next line is the beginning of CSV data...
column_label1,column_label2,column_label3
data1,data2,data3
:
:

It will be nice if I can ignore (and see in one color) those comment lines with additional options like:

"rainbow_csv.ignore_comment_line": true,
"rainbow_csv.comment_line_regexp": ^[#].*

Thank you and best regards, Kazzz

@Timmmm, I can! And I actually already implemented this in the “rfc” branch along with many other changes. I am planning to publish a new version in about 2 weeks.

@lucky-wolf You can check if it is working or not by hovering your cursor over the comment line: instead of the column info it will show “Comment” or something like this. Setting Comment_prefix also allows Rainbow CSV to efficiently run separator autodetection, affects Align/Shrink and Multi-cursor edit logic. I am also planning to add support of Comment prefix to RBQL. Unfortunately it is not possible to change color of lines with the comment prefix to the comment color because of some VSCode limitations ( I know about the “decorations” feature but it didn’t work well in my tests ). I hope this will change in the future and comment lines would be correctly highlighted.
