1: Basic tcl syntax question
Posted by Devon Yoo on 10/28/11 08:07 PM
I found several basic tcl syntax on the web but they are not working on my computer!!

----------------------------
proc foo {a b} {puts "$a $b"}
foo a b
----------------------------
->prints nothing

----------------------------
doc_return 200 "text/html" "Hello"
doc_return 200 "text/html" " World"
----------------------------
->this prints only "Hello"

What is wrong???

puts outputs to stdout and not to the web connection.

doc_return returns a document and closes the connection.

What are you trying to accomplish?

keep on keepin on...

yes tcl is very different from php, and while you're coming up to speed you'll run into a buncha stuff...

proc foo {a b} { return "$a $b" }

doc_return 200 "text/plain" [foo "ayyy" "beee bayyybee"]

try something like that... or, use acs-templating:

foo.tcl:

ad_page_contract {test/exercise foo proc} -properties {
  out : onevalue
}

proc foo {a b} {return "$a $b"}

set out [foo "ayy bee" "bayyy bee"]

and, foo.adp:

@out@

-or-:

foo.adp (foo.tcl as above):

<master>

<ul>
  <li>@out@</li>
</ul>

Oh, and the template files go in yourOacsInstance/packages/yourPackage/www/

And if you have foo.tcl and foo.adp in there, then you would mount a new instance of yourpackage somewhere, using the site map, say it's mounted on /pkg.

then, you can access it as http://your.site/pkg/foo
