Using stacks in MC CGI scripts...
OK getting back to some CGI stuff... Help from all you experts out there required. I have an MC based CGI working but when I use the following lines within the standard "echo.mt" test script I get errors: -- go to stack "database.mc" -- error -- start using stack "database.mc" -- no problem but... -- put getData() into buffer -- error Now getData() is a very simple function in the stack script of the MC stack "database.mc" on the server - it just return "hello" I am not clear what can and can't be done with these scripts as I had largely worked with MC based server stuff where it is all possible, so anyone help with my confusion???

I don't have two stacks... just the one and it is being "used" in the .mt script - by the "start using stack ..." line.

I don't have two stacks... just the one and it is being "used" in the .mt script - by the "start using stack ..." line. Same thing. However i can't use any of the functions in this stacks script even though I can reference it's fields and data So, the syntax is the problem. After you "start using" a stack do a handler in the stack not a function. In your .mt file: ...start using "database" getMyStuff put the result ... In your stack script: on getMyStuff put getData() into buffer return buffer end getMyStuff function getData() #stuff end getData Archives: http://www.mail-archive.com/metacard@lists.runrev.com/ Info: http://www.xworlds.com/metacard/mailinglist.htm Please send bug reports to [EMAIL PROTECTED], not this list.

Thanks Andu,
got it working (with your help). I had made a number of mistakes...
1) The function had a mistake:
function getData
-- put return fld 1 into someData
put return fld 1 of stack "database" into someData
return someData
end getData
Basic mistake, but as the script is being used, it had no idea of which
stack the field was in - so a stack reference was needed. However you can
call the functions direct (which is a relief for me 'coz my libraries are
mainly functions).
Seem to be able to parameters in the expected way. However I've run into a
problem which seems to be to do with the home stack... pretty sure it is not
corrupted or anything as it works locally and I am using the same technique
to transfer it as the other stacks... - I think it is *that* lovely splash
screen -:)
Why would I want to use the home stack
Good question.
- maybe I don't need to, but when
exploring shell commands, I decided to see if I could use MC shell commands
and call them from the CGI...
Stuff like (calling standard shell scripts on Linux serveer):
-- put shell("whereis sh") after buffer
-- put return after buffer
-- put shell("whereis mc") after buffer
-- put return after buffer
-- put shell("whereis perl") after buffer
-- put return return after buffer
Works a treat in the CGI, but when I tried to use MC based scripts...
First I got back that sh (the shell interpreter) couldn't handle it, so I
needed to change the shellCommand...
-- set the shellcommand to "mc"
to which I get back...
-- ...mcPath: Can't open display
-- ...mcPath: Can't load stack or script mchome.mc
Which brings me on th the fact that with the home stack on the server and a
couple of database stacks:
-- put fld 1 of stack "database" into someData -- works fine
-- put fld 1 of stack "home" into someData -- gives a server error
So the question I am trying to answer is have I made another silly mistake
or am I running into a brick wall as the home stack will not run on the
server (display issue?) and consequently I won't be able to use MC based
shell scripts?
You can if they are written to a .mt file.
% ./mc script.mt # will execute the script.
Doing:
% ./mc stack.mc #will try to open MC in X and not succeed.
Maybe I'll have to dig out that SSH Telnet client? Any help from the experts
out there appreciated...

Can be any file name as long as the permissions are set to execute and the
file is on the $PATH right?
If you're not in the directory with the file you have to point to it (%
mc /home/users/www/cgi-bin/script.mt) "%, $, #" stay for the promt sign
which in my case is # (they are not part of your command). If the
application is not on the $PATH you must point to it; same for the
script file:
% /usr/local/bin/mc /home/users/www/script.mt
If you're in the same directory with mc and mc is not on the $PATH you
do:
%./mc script.mt (or the path to the script).
% ./mc script.mt # will execute the script.
Has this come through the email correct? What do I issue from an MC .mt CGI
script (or other CGI language? Lets take MC as an example:
put shell("% ./mc script.mt") into mcShellResult
So, if mc is on the path you do:
put shell("mc /path/to/the/script.mt")
The preffix of the file can be anything not just .mt.
Doing:
% ./mc stack.mc #will try to open MC in X and not succeed.
OK
Thanks again.
You're welcome.
