Re: [racket-users] Using get-file in racket/gui ...

[Sorawee Porncharoenwase]

The Racket Reference has a section on the notation used in documentations:
https://docs.racket-lang.org/reference/notation.html

But yes, what you said is correct: you are forced to specify every prior
optional positional argument. This is why I think optional positional
arguments are bad in general. Optional keyword arguments are much better.

Re: [racket-users] Using get-file in racket/gui ...

[Don Green]

Where is the documentation that describes how to interpret the racket 
syntax?
For example:
(get-file  (message parent directory ...)) ;where the arg list of options 
are optional but if included are positional meaning that to specify an 
argument such as 'directory' means that the previous 2 args must also be 
specified.

Of course, I meant the third, not fourth.  Oops!

It seems like the second argument is the message shown in the title of the 
pop-up window.  You can include a path as the fourth argument:


(get-file #f f "/home/don/projects")

I expected the following to display the popup showing the specified directory

(get-file (string->path "/home/don/projects") f)

Any suggestions?
