| <h2>Tcl Scripts</h2> |
| <div> |
| <p> |
| Pure Tcl scripts let you do the heavy lifting to control your application. A sensible |
| design pattern is to put most of your complex logic in these files, and then parse template |
| files to display the results. This means that those who are creating the HTML files don't |
| have to know much Tcl, and only need to call a few simple commands. |
| </p> |
| <p> |
| <pre class="programlisting">proc chat::model::getlines {user} { |
| set sk [chat::model::getsock] |
| puts $sk [list user $user cmd get msg ""] |
| if { ! [eof $sk] } { |
| gets $sk data |
| return "$data" |
| } else { |
| error "Problem with socket" |
| } |
| }</pre> |
| </p> |
| <p> |
| For instance scripts are useful when you want to have control of the http protocol and you are not transmitting |
| text/html data. See the example regarding the <a href="file%5fdownload.html">file download</a> |
| |
| |
| or the xml messaging in <a href="ajax.html">Ajax</a> |
