Hi, Thanks for getting things going on this again João. Based on what is in org-element-example-block-parser and org-element-src-block-parser I think
:number-lines (yes|no|continue) as João proposes :indent (preserve|align|???) not sure about naming :labels (link|keep|remove|remove-whitespace) :label-format regexp-string Defaults would be :number-lines no, :indent align, :labels remove-whitespace and :label-format would inherit from the default. The remove-whitespace option would remove the label itself along with any whitespace leading up to it, this avoids the user needing to specify the leading whitespace in :label-format. The remove option by itself is retained in the event that someone has aligned their labels and wants to retain the whitespace. This may be too complex though and remove-whitespace is not needed because :label-format can be modified as needed. Header arguments need to have a single value, so I think we should split :labels and :label-format, that way users can also specify :label-format without having to specify :labels first (otherwise there is ambiguity about what a single argument :labels means. Best, Tom
