We have just released updates to Maple and MapleSim.

Maple 2020.2 includes corrections and improvements to printing and export to PDF, support for macOS 11.0, more MATLAB connectivity, resolves issues with the installation of the Maplesoft Physics Updates, and more.  We recommend that all Maple 2020 users install these updates.

This update is available through Tools>Check for Updates in Maple, and is also available from our website on the Maple 2020.2 download page, where you can also find more details.

If you are also a MapleSim user, this Maple update will be installed automatically when you update your MapleSim installation to the newly released MapleSim 2020.2. The MapleSim update also includes many updates to MapleSim, the MapleSim CAD Toolbox, specialized MapleSim libraries, MapleSim connectivity tools, and MapleSim Insight.  You will find details about new features and improvements, as well as instructions on obtaining the update, on the MapleSim 2020.2 page.

I created a little procedure to automatically size text areas based on content. It sizes the text area based on wraparound and tab characters, something that the autosize for the code edit region does not do. (Hint to Maple developers)


    AutosizeTextArea:=proc(TextAreaName, {intMinRows::nonnegint:=5, intMinChars::nonnegint:=50, intMaxChars::nonnegint:=140})
        description "Autosizes the TextArea based on content",
                  "1) TextAreaName__The name of the textarea",
                  "Optional Parameters",
                  "intMinRows________Minimum number of visible rows",
                  "intMinChars_______Minimum character width",
                  "intMaxChars_______Maximum character width";
        uses DocumentTools, StringTools;          
        local strLines, intLongestLine, nLines;
        strLines := Split(GetProperty(TextAreaName,'value'),"\n");
        intLongestLine := max('numelems'~(strLines));
        # Count the characters in each line (add 7 extra characters for each tab). Determine the number of lines to display each line due to wraparound, then add all these together
        #   to determine the number of rows to display.
        nLines := add(ceil~(('numelems'~(strLines) + StringTools:-CountCharacterOccurrences~(strLines, "\t")*~7)/~intMaxChars));
        SetProperty(TextAreaName, 'visibleRows', max(nLines, intMinRows), 'refresh' = true);
        SetProperty(TextAreaName, 'visibleCharacterWidth', min(max(intLongestLine, intMinChars),intMaxChars), 'refresh' = true);
    end proc:
