Submit JSON using commandline?

Hi,
I try to submit a JSON as comandline parameter.
I tried this one-liner to test:
Code: Select all
MessageRequester("Test", ProgramParameter(0) + #CRLF$ + ProgramParameter(1))
I did not manage to find out in which way the quotes have to be escaped to work.
I tried
\",
""",
^" and some others but with no success. Google is not helpful.
Any idea? How to submit double quotes in a commandline parameter?

Is using GetCommandLine_() on Windows an option for you?

Hi Danilo,
Thanks, but there are multiple parameters. So I have to do all the parsing by myself. I believe this is something that should be handled by the Operating System or at least by the development environment (PB). Or am I wrong? I have no problems with this on MacOS and Linux.
Is there a valid way for Windows to submit strings containing double quotes as commandline parameters?

The correct way of escaping quotes under Windows is "hello ""pb"" world",
which will result in >>hello "pb" world<<. Unfortunately this doesn't work
with PB's parameter commands as it seems that PB is screwing this up.
I did a quick test with another language and it worked flawlessly.
Couldn't get it to work under PB. Maybe you can try a WinAPI approach
using GetCommandLine_() and CommandLineToArgvW().

If no other trick will work, maybe you can pass
on the command line, and then your program replaces
' with
" ?
Just an idea.

Well that's depending on the programmer, of course.
There is no such limitation.

He prepared a 'stringified' json and not an object view notation, both element as value have quotes.
Afaik in that case crlf is not part of json.

Of course you can use line breaks.
But maybe I'm just completely wrong...

once you start escaping and adding quotes after quotes then you are still hand processing each parameter.
I use a few simple rules: no double quotes unless there are spaces, the colon should be together with key and space
on both sides of comma.
Code: Select all
yourprogram.exe { position: relevant , json: "not for CMD" }
this will give index
(0) "{"
(1) "position:" notice how there is no space btw ":" and key
(2) "relevant"
(3) , comman
(4) "json:" again with the colon attached to key
(5) "not for CMD" here the quotes have served their purpuse of keeping spaces in place
(6) "}" end of the whole thing
