I've attached a patch so that environ can be supported from GST.

And this is what my final test-cgi.st script looks like :)
Just ignore the fact that I use GNU style for naming my variables
rather then the CamelCase style that is the convention in Smalltalk.

------ BEGIN CODE ----------
#!/usr/local/bin/gst -f

Transcript showCr: 'Content-type: text/html'; nl .
'' displayNl .
'<HTML>' displayNl .
'<HEAD><TITLE>Testing CGI/Smalltalk</TITLE></HEAD>' displayNl .
'<BODY>' displayNl .
'<H2>Yo! Smalltalk, Whats up ? </H2>' displayNl .

env := Smalltalk environ .
env_dict := Dictionary new.

[ (env_string := env value) isNil ] whileFalse: [
match := env_string =~ '(.*?)=(.*)'.
env_dict at: (match at: 1) put: (match at: 2).
env incr ].

env_sorted := env_dict keys asSortedCollection.

Transcript nl ; showCr: '==== All Env Vars below ====== <br>'; nl.
env_sorted do: [ :a_key |
Transcript show: a_key .
ans := env_dict at: a_key.
Transcript show: ' = '; show: ans; cr.
].

'</BODY>' displayNl .
'</HTML>' displayNl .

-------------- END CODE ------

Thanks for the help Paolo and the patience. Hopefully the patch makes it in.

cheers,

mehul

In reply to this post by Mehul Sanghvi-2

Doesn't seem like the patch I had sent previously made it in.

I just did a "git pull" for the first time since March 2011, and the
patch wasn't in there.

Any chance it can be included ? It is attached to this email.
