Hi,
As Pascal mostly well known as a safe, easy to read, and elegant language,
don't you think Pascal needs named parameter? I mean for ALL kind of
parameters, not just for Variants. When you have a function with many
parameters having default values, you know that named parameter is
desirable. For example:
function f(p1: string = ''; p2: integer = 0; p3: boolean = false);
But you only need to supply the third parameter, you still must supply the
first and second ones with appropriate default values, like this:
f('', 0, true);
while with named parameter, you can do this:
f(p3 := true);
I believe it would raise Pascal's code readability. I know it has been
discussed before. I know somehow the parser had been able to read such
syntax. So, why don't we have the option to enable it for people who want
it? Kinda a syntax switch mode.
What do you think? :)
Opinions on what constitutes readable code clearly differ :)
But as far as I know, the parser is not able to read this syntax ?
The parser supports it for dispatch calls on variants (both methods
and properties). You even wrote that in your own article about Word
automation: https://www.freepascal.org/~michael/articles/word/word.pdf
;)
Yes, in Delphi. But I didn't know FPC also supports it ?
Michael.
