For example, to pass conditionally different values as an argument for a constructor of a field or a base class, it is impossible to use a plain if-else statement; in this case we can use a conditional assignment expression, or a function call. Bear in mind also that some types allow initialization, but do not allow assignment, or even that the ...
{{if either (|a) (|b) (|first result) (|second result)}} "If either (a or) (b) is true, (return first result,) (else return second result)."This helper template is ...
By definition, a code comment is text that is ignored by the translator – the browser, IE, in this case. But, the conditional comment feature adds syntax for a conditional statement that is formatted as a comment. Therefore, some text that is formatted as a comment is actually not a comment. It is markup code.
The functions are simple data validation and data type checking functions. The data validation functions determine whether it is possible to convert or coerce the data value given as an argument to the function to the type implied by the function name, and return a Boolean value recording whether it was possible or not.
The basic syntax remains very similar: conditions, loops, procedures, sub-routines are declared and written in the same manner (see Visual Basic). Mobility from prior Visual Basic iterations to Visual Basic .NET really are parts of existing code: programmers with experience in both worlds are required to effectively target the new platform with ...
invokes a function named if passing 2 arguments: The first one being the condition and the second one being the true branch. Both arguments are passed as strings (in Tcl everything within curly brackets is a string). In the above example the condition is not evaluated before calling the function.
This parser function can be used to detect whether a template parameter is defined, even if it has been set to a false value. For example, to check whether the first positional parameter has been passed to a template (note that the strings "+" and "-" can be any two different non-whitespace strings):
