"overscored" or "overlined" text … (or whatever it should be called)

"overscored" or "overlined" text … (or whatever it should be called)

[Robert Blackstone]

[-- Attachment #1: Type: text/plain, Size: 1549 bytes --]

Dear all,

I am trying to reproduce with ConTeXt an old french text that contains numerous abbreviations, mostly of two types:
- words cut off by means of a "period", with the last letter of the complete word as a superscript above the period.
- "overscores"
  --either for single characters, for instance in words with double consonances, like "comme". One of these is sometimes omitted and replaced by an "overscore" on the previous vowel
  -- or on an entire abbreviation, such as "coe" for "comme" and "nre" for "notre"; they become coe and nre overscored.

Now I would like to reproduce these as closely as possible.

For the "period + superscript letter" I found  a solution: \lohi[]{\cdot}{t} (for superscript t), nearly perfect. The only imperfection I can see is that the dot sits slightly below the baseline. Is there a way to get it on the baseline?

The overscore on a single character presents no problem.

For an overscore on a complete word I have not found a solution. 
Three individual overscores on a three-letter word give a broken line; I do not know how to merge the three line components. (Incidentally, this hack does not work with mkiv)

The other solution I have tried is to put the word in a frame with a top-frame only. But this way the word (abbreviation) hangs underneath the base-line. 
Using \inframed instead of \framed  makes no difference. There appears not to be something like \setupinframed.

I have attached an example.

Thanks in advance for any help.

Regards,

Robert Blackstone

\overbar{test}

btw, never do a \setupframed globally as it will infect many derived 
frames components ... best do a \defineframed ... then

while we are at it: how to do do strikethrough text? there is a changelog
on contextgarden which says it was added, but \strike or \strikethrough are
not defined.

i have (a diagonal) one here, but it doesn’t really work in math mode (the
text inside is normal). that being said, is there something like
\ifthiswascalledinmathmode{then}{else}?

\def\strike#1{\tikz[baseline=(c.base)]{
    \node[inner sep=0pt] (c) {#1};
    \draw (c.south west) -- (c.north east);
}}

probably more efficient:

\startuniqueMPgraphic{strikeme}
     path p ; p := OverlayBox topenlarged -ExHeight bottomenlarged 
-ExHeight ;
     draw llcorner p -- urcorner p withcolor OverlayColor ;
\stopuniqueMPgraphic

\defineoverlay[strikeme][\uniqueMPgraphic{strikeme}]

\defineframed[StrikeMe][background=strikeme,frame=off,offset=0pt,location=low,backgroundcolor=blue]

\starttext

\dorecurse{100}{test \StrikeMe{now \recurselevel} test $\StrikeMe{x}$ 
test \StrikeMe{$x$} test }

unfortunately this does the same as my tikz version: it exits math mode:

$\StrikeMe{\ifmmode math mode! \else no math mode :( \fi} \ifmmode math
mode. \else wat \fi$

returns

no math mode :( *mathmode.*

\framed puts the content in a \hbox and when you put a \hbox in a math environment the text in the box is typeset in text mode, this feature is used for the \text command. To get now the content of the \StrikeMe command in math mode a different definition.

\defineframed[StrikeMeFrame][background=strikeme,frame=off,offset=0pt,location=low,backgroundcolor=blue]

\define[1]\StrikeMe
  {\ifmmode
     \StrikeMeFrame{$#1$}%
   \else
     \StrikeMeFrame{#1}%
   \fi}

Better is to use: \StrikeMeFrame{\mathsurround\zeropoint$#1$}. But for 
this to work in subscripts and superscripts, you must use math palette. 
IIRC, \mframed does that. In principle:

\mframed[background=strikeme]{...}

should work (untested).

@Hans: Can we have \definemframed etc as well?

Don't use {... \over ...} as it will mess up the calculation of math 
style. \frac{...}{...} is more robust.
