Maple support for Visual Studio Code

Syntaxes Highlight & Theme

The highlight theme Dark+ for maple is based on the vscode default Dark+ theme, added some color settings for the maple elements.

To change the theme, you can press ctrl+shift+P and search Theme, click Preference: Color Theme, and select the Maple Dark+ or Maple Light+.

If you don't like the color, you can change it in ./themes/maple_dark.json or ./themes/maple_light.json.

Support elements include:

• line comment: #
• block comment: (**)
• keywords
• string: surround with "", and handled escaping but ignore its correctness.
• quoted names: surround with ``, and handled escaping but ignore its correctness.
• unevaluated expressions: the '' can be used as () for expressions, so it's difficult to match these expressions, this extension just support mult-quoted unevaluated expressions such as 'x' and ''x'', expressions like ''x'+y' can not be highlighted correctly.
• preprocessor: such as $include. Notice: In Maple, the introducer $ must appear as the first character of a line to be recognized as a preprocessor directive.
• proc and module options. But deleted trace option, because it is rarely used, and can be instead of the trace function.
• maple functions.
• support extensions: mpl,mm,mi .

Maple Code Runner

Firstly, you should set the path of cmaple.exe.

"maple.cmaplePath":"${Maple Install Path}/bin/cmaple.exe"

And you can set the output option maple.isPrettyPrint to be true or false (default is false).

"maple.isPrettyPrint":true or false

Example for true

> solve(x^2+x-1);
                   1/2                 1/2
                  5                   5
                  ---- - 1/2, - 1/2 - ----
                   2                   2

Example for false

> solve(x^2+x-1);
1/2*5^(1/2)-1/2, -1/2-1/2*5^(1/2)

To run maple code, you can right click and select the Maple Runner menu. Or, you can press ctrl+shift+alt+m. While there is any code selected, it will run the selected code instead of run the whole file.

Notice:

• it only support codes that can run in cmaple.exe.
• every line should end with ; or :.
• not support preprocessor commands.
