Typesetting a double Over Dot on top of a symbol












6












$begingroup$


I wanted to make a notation with a double dot over a symbol in Mathematica. Searching online or in the documentation did not yield any results. However, just randomly attempting to give a second parameter to the OverDot function surprisingly did exactly what I needed:



enter image description here



I assume the red font suggests that Mathematica perceives this as a syntax mistake at some level, even though the output is as desired. Unfortunately, this does not work for three dots and more.




Is there a proper way to do this without red font appearing?

    The code editor and documentation are not always completely in sync with the actual typesetting. This is only one of several examples. Ignore the code coloring.

    @BobHanlon as a German speaker I perceive your Overscript[x, ".."] Umlaut to be very improperly typeset. Overscript[x, "¨"] is bad as well. They work, yes; but not for publication. Cheers!

    @Roman Why not just literally use the German character set for that? The double dot over a symbol has e.g. the meaning of a second time derivative in Physics -- which is typeset properly.

    For Umlaut characters you only get äëïöüÿ from the font set but not the others. That wasn't my point though. All I'm saying is that the size of the dots and their distance must be appropriate for the chosen font, otherwise it looks very bad for a native speaker of German, Turkish, Swedish, French, etc. If you don't care about the aesthetics, then all the given solutions work, sure.

Use ToBoxes to find the boxes generated for OverDot[x, 2]:



OverDot[x,2] //ToBoxes



OverscriptBox["x", "¨"]




You can reproduce these boxes using Overscript:



Overscript[x, RawBoxes @ "¨"]



enter image description here




You can use the same approach for triple dots:



Overscript[x, RawBoxes @ "[TripleDot]"]



enter image description here




For more dots, you will have to use a different mechanism to generate the dots, e.g.:



Overscript[x, Style[Row[{".",".",".","."}],FontTracking->"Condensed"]]



enter image description here




Update



You could also overload OverDot to work with the 3 and higher versions (I also included @Michael's syntax information fix):



SyntaxInformation[OverDot] = {"ArgumentsPattern" -> {_, _.}};

MakeBoxes[OverDot[a_, n_Integer?(GreaterThan[2])], StandardForm] := If[n==3,

    OverscriptBox[MakeBoxes[a], "[TripleDot]"],

    OverscriptBox[

        MakeBoxes[a],

        ToBoxes @ Style[Row[ConstantArray[".", n]], FontTracking->"Condensed"]

    ]

]


Then:

        There indeed is a [DoubleDot] template, but it actually leads to an expression with the FullForm OverDot[X,2]! So the syntax is in fact intended, then I'm confused why Mathematica marks it in red font when typed in directly?

        $begingroup$
        Yes... confusing. The documentation for OverDot shows only one argument... so the $2$ is somehow treated extraneously. (Perhaps a bug report is in order.)

                        There indeed is a [DoubleDot] template, but it actually leads to an expression with the FullForm OverDot[X,2]! So the syntax is in fact intended, then I'm confused why Mathematica marks it in red font when typed in directly?

                        Yes... confusing. The documentation for OverDot shows only one argument... so the $2$ is somehow treated extraneously. (Perhaps a bug report is in order.)
