Emmanuel Bourg updated CLI-116:
-------------------------------
Component/s: (was: CLI-2.x)
Help formatter
> Allow to configure the width of the first column on the
> HelperFormatter.print() method
> --------------------------------------------------------------------------------------
>
> Key: CLI-116
> URL: https://issues.apache.org/jira/browse/CLI-116
> Project: Commons CLI
> Issue Type: Improvement
> Components: Help formatter
> Affects Versions: Nightly Builds
> Reporter: David Leal
> Fix For: 2.1
>
>
> Just to suggest to allow the user to control the with of the first column of
> the generated output from HelperFormatter.print() method, for the option
> description.
> Now this with is delimited by the longest option and some times it is not the
> best solution, because the width of the second column (description) in order
> to fix the maximum length (default 80) has to be short.
> My suggestion is to give the possibility to the user to wrap the option
> definition (first column), in case it is going to be longer to a given value.
> This is useful for group options, for example something like this:
> -report (-r)
> -date|-list|-template|-param-names|-param-values|-format
> -date (-d) date
> -list (-l)
> -template (-t) template [template ...]
> -param-names (-pNames) name [name ...]
> -param-values (-pValues) value [value ...]
> -format (-f) format [format ...]
> so the description field will be started after the longest option definition,
> at column position after:
> -date|-list|-template|-param-names|-param-values|-format
> a better solution would be nevertheless to wrap also this line to a given
> length, for example:
> -report (-r)
> -date|-list|-template|-param-names
> |-param-values|-format
> -date (-d) date
> -list (-l)
> -template (-t) template [template ...]
> -param-names (-pNames) name [name ...]
> -param-values (-pValues) value [value ...]
> -format (-f) format [format ...]
> it is easy to see the line is wrapped because the indentation level, so now
> the second column, that is the description, will come after the -param-names
> option definition which is now the longest option definition.
> Thanks in advance,
> David Leal
