Is there a way to support --switch=parameter syntax ??

[rwilcox]

Given the following program --help generates help text that doesn't seem to support --parameter=text format, but --parameter text

#lang cli

(flag (file  in-file-path)
      ("-f" "--file" "filepath")
      (file in-file-path))

(program (hello)
  (displayln (file))
)

(run hello)

CLI output:

PS ... > D:\Racket\Racket.exe .\tmp.rkt --help
usage: hello [ <option> ... ]


<option> is one of


  -f <in-file-path>, --file <in-file-path>
     filepath to write the changelog to. Can NOTE use --file=foo must use --file foo
  --help, -h
     Show this help
  --
     Do not treat any remaining argument as a switch (at this level)

 *   Asterisks indicate options allowed multiple times.

 Multiple single-letter switches can be combined after
 one `-`. For example, `-h-` is the same as `-h --`.

PS ...> D:\Racket\Racket.exe .\tmp.rkt --file hello
hello
PS ...> D:\Racket\Racket.exe .\tmp.rkt --file=hello
hello: unknown switch: --file=hello
PS C:\Users\aias\Documents\Development\simple_changelog>

(but thank you very much for making this little language!)

Hi @rwilcox ! This package does not parse the command line syntax directly but instead simply leverages the command line arguments and flags reported by Racket's built-in current-command-line-arguments parameter. I did a quick google search to get a sense of how common the = syntax is, and I couldn't really say. At least one link mentioned it, but other links seemed to be unaware of it. Do you happen to know if it is considered a UNIX standard? If so, you may want to open an issue on the Racket repo directly to recognize this syntax in the core command line utilities. What do you think?

[rwilcox]

It’s in the libc docs, so I’m guessing it’s pretty common 😄

But OK, I may take a look at writing a command line program with the core utils, repro the issue and open a bug with Racket, that’s a good idea.

You can probably just use the example in the docs on the built-in command line utilities, which should be runnable as is. E.g. "link-flags" there takes an argument at the command line.

This has been on my radar for a while, but finally did something about it: https://github.com/racket/racket/issues/4106
