Subject [jira] [Commented] (CSV-84) Comment handling
Date Mon, 26 Mar 2012 21:38:32 GMT

    [ https://issues.apache.org/jira/browse/CSV-84?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13238874#comment-13238874
] 

Sebb commented on CSV-84:
-------------------------

I don't know if there are formats with inline comments.
The code currently recognises comments at the start of a value as well as at the start of
a record. 
This behaviour may be unintentional.

I agree that empty lines are generally not needed, but a comment line may not be useless.

> Comment handling is not currently fully documented / tested.
> There are several possible situations:
> 1) trailing comment following one or more values
> 2) comment marker starts in the first column
> 3) comment marker starts in the first non-whitespace column
> How should these be handled?
> 1) The trailing comment should be ignored
> 2) Entire line should be ignored, i.e. don't treat it as a blank line
> 3) This is trickier: if whitespace is being trimmed, treat as 2, else treat as 1, i.e.
there is a single value containing whitespace
> It might also be useful to consider returning comments to the application program as
part of CSVRecord.
