upcase-initials-region on show-duvall-jefferies-etal-1993

[steve-humphreys]

I have strings in a file of the form "Show-Duvall-Jefferies-etAl-1993".

Would like to switch between the following three versions

"Show-Duvall-Jefferies-Etal-1993"  ;
"SHOW-DUVALL-JEFFERIES-ETAL-1993"  ; can be done with upcase-region
"show-duvall-jefferies-etal-1993"  ; can be done with downcase-region
"Show-Duvall-Jefferies-Etal-1993"  ; cannot be done with upcase-initials-region

I am getting the bounds ($ma $mb) for the string like this

(defun alnum-dash-bounds ()
   "Gets bounds of a subword unit defined by [:alnum:] and dash."

   (let ( ($bounds nil) $ma $mb )

      (skip-chars-backward "[:alnum:]-")  ; same as ""[a-zA-Z0-9]-"
      (setq $ma (point))
      (skip-chars-forward "[:alnum:]-")
      (setq $mb (point))
      (cons $ma $mb) ))

I just tried this in your message and `upcase-initials-region` gave me
exactly what you seem to want, so you're going to need to give more
detail about what you mean by "cannot be done with".

Have just figured there was a problem with my configuration and one of the init files
was not being loaded properly.

Many thanks
