Binary Expressions

In Defining an Editor it was already mentioned that projections cannot be specified for binary expression concepts. The editor offers specialized support for binary expressions, which will not function properly if a user-defined projection is applied.

Symbols

You can, however, indicate the string to be used as the operator. This string is called the symbol. It is defined in the .edit file, as shown below.

// Insurance/src/defs/editor-expressions-default.edit#L18-L29

MinusExpression  {
    symbol = "-"
}
PlusExpression {
    symbol = "+"
}
MultiplyExpression {
    symbol = "*"
}
DivideExpression {
    symbol = "/"
}
