front end - Programming scripts to create and modify stylesheets: problems with contexts


I am trying to emulate the shift and shift+tab feature in the Outline.nb stylesheet that comes with Mathematica.


I added the following code to a private stylesheet at the notebook level.


Cell[StyleData["NUM"],
 CellDingbat->Cell[

   TextData[{
     CounterBox["NUM"], "."}]],
 CellMargins->{{80, 10}, {7, 7}},
 ReturnCreatesNewCell->True,
 StyleKeyMapping->{"Tab" -> "SubNUM"},
 CellGroupingRules->{"SectionGrouping", 50},
 DefaultNewCellStyle->"SubNUM",
 DefaultReturnCreatedCellStyle->"NUM",
 ParagraphIndent->0,
 CounterIncrements->"NUM",

 CounterAssignments->{{"SubNUM", 0}},
 MenuSortingValue->1200,
 MenuCommandKey->"1",
 FontFamily->"Times",
 FontColor->GrayLevel[0]]

Cell[StyleData["SubNUM"],
 CellDingbat->Cell[
   TextData[{
     CounterBox["SubNUM"], "."}]],

 CellMargins->{{120, 10}, {7, 7}},
 ReturnCreatesNewCell->True,
 StyleKeyMapping->{
  "Tab" -> "Outline3", "Backspace" -> "NUM", KeyEvent["Tab", Modifiers -> {Shift}] -> "NUM"},
 CellGroupingRules->{"SectionGrouping", 60},
 ParagraphIndent->0,
 CounterIncrements->"SubNUM",
 CounterAssignments->{{"Outline3", 0}},
 MenuSortingValue->1250,
 MenuCommandKey->"2",

 FontFamily->"Times",
 FontColor->GrayLevel[0],
 CounterBoxOptions->{CounterFunction:>(Part[
   CharacterRange["a", "z"], #]& )}]

So Shift and Shift+Tab work perfectly in the notebook containing the stylesheet. I tried them and they both work.


However, when if I create a new notebook and then apply the stylesheet to that notebook I loose the shift+tab feature. But for some reason the tab feature does transfer over. It seems to break only the shift+tab feature. As you can see in the animated gif below, the tab key works, but shift+tab does not work.


enter image description here



I use the function below to apply the styles in my master stylesheet notebook to any notebook I am working in.



ApplyStylesheet:=Module[{nb,stylesheet},

nb=NotebookOpen[$HomeDirectory<>"/Library/Mobile Documents/com~apple~CloudDocs/Ventura College/Mathematica/Master Settings/MStylesheet.nb"];
stylesheet=Options[nb,StyleDefinitions];
NotebookClose[nb];
nb=InputNotebook[];
SetOptions[nb,stylesheet];
];



Edit 2: @Kuba - I was able to verify that your code below works like a charm. However, I was still having issues using it in conjuction with my ApplyStylesheet function above. As it turns out


stylesheet=Options[nb,StyleDefinitions]


was not saving the contexts. As a solution for applying a master stylesheet to multiple notebooks, I name the master stylesheet configuration (like yours configuration below) and then call it within any notebook. Contexts are kept intact this way. Thank you!



Answer



One has to be extremely careful with Cell options that are not released in System` context. It seems that your problem is caused by additional $CellContext` given to KeyEvent Modifiers and Shift.


I've faced it with earlier: NotebookWrite a Cell with WholeCellGroupOpener option


With


FrontEnd`KeyEvent["Tab", FrontEnd`Modifiers -> {FrontEnd`Shift}] -> "NUM"

Stylesheet works for me.



but it is not the only thing that won't work, you have to fix:


FrontEnd`DefaultNewCellStyle (*and*)
FrontEnd`DefaultReturnCreatedCellStyle (*and*)
FrontEnd`ReturnCreatesNewCell

too. Cumbersome...




  • when I'm writing scripts to manipulate stylesheets I'm using string names for option names "ReturnCreatesNewCell" etc. Not documented but working. String option names for Cells





  • (New edit:) What if it is not you who specifies those options and you have to e.g. NotebookWrite cell contents that can have those not released symbols somewhere?




    • You can do a replacement just before doing this. Let's create a test cell: Cell["asd", "Subsection", WholeCellGroupOpener->True], now put before that cell


      CellPrint[
        NotebookRead[
           NextCell[]
        ] /. s_Symbol /; Context[s] === "Global`" :> Symbol["FrontEnd`" <> SymbolName[s]]
       ]


      It will generate correct copy, while without replacement you'd end up with $CellContext`.




    • Or you can force those unknown symbols to be put in FrontEnd` context when read:


      CellPrint @ Block[
        {$Context = "FrontEnd`", $ContextPath = {"System`"}}, 
        NotebookRead[NextCell[]]
      ]






SetOptions[
  EvaluationNotebook[],
  StyleDefinitions -> Notebook[{
    Cell[StyleData[StyleDefinitions -> "Default.nb"]],
    Cell[StyleData["NUM"], 
     CellDingbat          -> Cell[TextData[{CounterBox["NUM"], "."}]], 

     ReturnCreatesNewCell -> True, 
     StyleKeyMapping      -> {"Tab" -> "SubNUM"}, 
     CellGroupingRules    -> {"SectionGrouping", 50}, 
     DefaultNewCellStyle  -> "SubNUM", 
     DefaultReturnCreatedCellStyle -> "NUM", 
     ParagraphIndent      -> 0, 
     CounterIncrements    -> "NUM", 
     CounterAssignments   -> {{"SubNUM", 0}}, 
     MenuSortingValue     -> 1200, 
     MenuCommandKey       -> "1"]

    ,
    Cell[StyleData["SubNUM"], 
     CellDingbat          -> Cell[TextData[{CounterBox["SubNUM"], "."}]], 
     CellMargins          -> {{120, 10}, {7, 7}}, 
     ReturnCreatesNewCell -> True,
     StyleKeyMapping      -> {"Tab" -> "Outline3", "Backspace" -> "NUM", 
          KeyEvent["Tab", Modifiers -> {Shift}] -> "NUM"}, 
     CellGroupingRules    -> {"SectionGrouping", 60}, 
     ParagraphIndent      -> 0, 
     CounterIncrements    -> "SubNUM", 

     CounterAssignments   -> {{"Outline3", 0}}, 
     MenuSortingValue     -> 1250, 
     MenuCommandKey       -> "2", 
     FontFamily           -> "Times", 
     FontColor            -> GrayLevel[0], 
     CounterBoxOptions    -> {CounterFunction :> (Part[
           CharacterRange["a", "z"], #] &)}]
    }
   ]/. s_Symbol /; Context[s] === "Global`" :> Symbol["FrontEnd`" <> SymbolName[s]]
 ]

plotting - Plot 4D data with color as 4th dimension

I have a list of 4D data (x position, y position, amplitude, wavelength). I want to plot x, y, and amplitude on a 3D plot and have the color of the points correspond to the wavelength. I have seen many examples using functions to define color but my wavelength cannot be expressed by an analytic function. Is there a simple way to do this? Answer Here a another possible way to visualize 4D data: data = Flatten[Table[{x, y, x^2 + y^2, Sin[x - y]}, {x, -Pi, Pi,Pi/10}, {y,-Pi,Pi, Pi/10}], 1]; You can use the function Point along with VertexColors . Now the points are places using the first three elements and the color is determined by the fourth. In this case I used Hue, but you can use whatever you prefer. Graphics3D[ Point[data[[All, 1 ;; 3]], VertexColors -> Hue /@ data[[All, 4]]], Axes -> True, BoxRatios -> {1, 1, 1/GoldenRatio}]

plotting - Filling between two spheres in SphericalPlot3D

Manipulate[ SphericalPlot3D[{1, 2 - n}, {θ, 0, Pi}, {ϕ, 0, 1.5 Pi}, Mesh -> None, PlotPoints -> 15, PlotRange -> {-2.2, 2.2}], {n, 0, 1}] I cant' seem to be able to make a filling between two spheres. I've already tried the obvious Filling -> {1 -> {2}} but Mathematica doesn't seem to like that option. Is there any easy way around this or ... Answer There is no built-in filling in SphericalPlot3D . One option is to use ParametricPlot3D to draw the surfaces between the two shells: Manipulate[ Show[SphericalPlot3D[{1, 2 - n}, {θ, 0, Pi}, {ϕ, 0, 1.5 Pi}, PlotPoints -> 15, PlotRange -> {-2.2, 2.2}], ParametricPlot3D[{ r {Sin[t] Cos[1.5 Pi], Sin[t] Sin[1.5 Pi], Cos[t]}, r {Sin[t] Cos[0 Pi], Sin[t] Sin[0 Pi], Cos[t]}}, {r, 1, 2 - n}, {t, 0, Pi}, PlotStyle -> Yellow, Mesh -> {2, 15}]], {n, 0, 1}]

plotting - Mathematica: 3D plot based on combined 2D graphs

I have several sigmoidal fits to 3 different datasets, with mean fit predictions plus the 95% confidence limits (not symmetrical around the mean) and the actual data. I would now like to show these different 2D plots projected in 3D as in but then using proper perspective. In the link here they give some solutions to combine the plots using isometric perspective, but I would like to use proper 3 point perspective. Any thoughts? Also any way to show the mean points per time point for each series plus or minus the standard error on the mean would be cool too, either using points+vertical bars, or using spheres plus tubes. Below are some test data and the fit function I am using. Note that I am working on a logit(proportion) scale and that the final vertical scale is Log10(percentage). (* some test data *) data = Table[Null, {i, 4}]; data[[1]] = {{1, -5.8}, {2, -5.4}, {3, -0.8}, {4, -0.2}, {5, 4.6}, {1, -6.4}, {2, -5.6}, {3, -0.7}, {4, 0.04}, {5, 1.0}, {1, -6.8}, {2, -4.7}, {3, -1....
