Hi all,
I recently transitioned from LaTeX to ConTeXt. There was some particular
thing I needed to do (which escapes me at the moment) that was far, far
easier to do in ConTeXt than in LaTeX. And, as I've learned, I've found
that that's quite often the case. So, a huge thank you to everyone
involved.
A couple hours ago I was annoyed that I couldn't find an equivalent for
the LaTeX 'cancel' environment/command/style(?)[1]. Now, I'm truly amazed
that 'cancel' required a whole package.
After discovering that 'underline' and 'strikethrough' were implemented as
overlays, I quickly coded up the following:
\startuseMPgraphic{MyCancel}
draw (0,.2*\overlayheight)--(\overlaywidth,\overlayheight);
\stopuseMPgraphic
\defineoverlay[mycancel][\useMPgraphic{MyCancel}]
\def\cancel#1{\framed[background=mycancel,frame=off]{#1}}
Now, I'm sure this is not *quite* the right way to do it. The 'cancel'ed
items end up being placed too high on the line, and other spacings are
slightly off. But, taking a cue from underlining, I kept the MyCancel
graphic and tried:
\definetextbackground
[cancel]
[location=text,
alternative=1,
background=mycancel]
% plus boilerplate for setting up \startcancel\stopcancel
...But, while composing this email, I found what I wanted, which still
isn't ``right'' in some sense:
\def\cancel#1{\framed[background=mycancel,frame=off,width=fit,height=fit,strut=no]{#1}}
I found the parameters for \framed. I'm still learning to Read The
Fantastic Manuals, but sent this anyway since I wanted to say thanks.
Best,
Ben
