Hello,

As I can tell you are using the read_multi_fwf function. It uses fwf_widths. Perhaps it would be better to accect a col_positions object and let the user decide which one to use. This is what tried to do with the read.multi.fwf function. It seems with the read_multi_fwf I missed that.

I will try to update it before the end of March.

Thanks

@prontog thanks for the reply. I could also try supplying widths with negatives for the widths on undesired columns. I'll let you know if it works. Good function by the way, surprised there isn't more similar functionalities out there...

@prontog Just submitted a PR.

I did not add any tests but I did test it out locally on a project I am working on and it worked great !

@jimbrig2011 you mean that the negative width works with readr::read_fwf? I thought it only worked with read.fwf. Nice. Will take a look on your PR ASAP.
