Auto-detect comments

[bestouff]

Hi,

I have a CSV file like this:

# comment 1
# comment 2
col1;col2;col3
data1;data2;data3
data1;data2;data3

Would it be possible to have the comment somehow auto-detected ? Or at least a command to inform the plugin that # is a start-of-comment ?

How should the plugin detect comments automatically? It uses the &commentstring option currently to do so. I am not sure, what better ways it could use.

I thought maybe if all lines that don't contain the column separator start with the same character, this is the start-of-comment ?

Anyway I tried :set commentstring="#%s" but that didn't seem to change anything - at least the syntax highlighting didn't change. So I wasn't sure if comments are handled by csv.vim.

You need to re-init the plugin. Run CSVInit after changing the comment character.

Well, this results in:

Error detected while processing function <SNR>249_CheckSaneSearchPattern:
line   37:
E684: list index out of range: 0

and then when pressing a cursor key:

Error detected while processing function csv#MoveCol[6]..csv#MaxColumns:
line   12:
E684: list index out of range: 0
E116: Invalid arguments for function escape(b:csv_cmt[0], '\\')
line   13:

Hmm missing space I believe in the commentstring option. Will fix it tomorrow.

:set commentstring="#%s"

That obviously needs to be :set commentstring=#%s, note the missing ", which Vim sees as comments and hence the errors in the csv#MaxColumns functions.

That looks wrong. Please show the output of the following commands:

 :redir => a |sil filetype | redir end
 :echo a

Also, what Vim version is this?
