template::adp_compile (public)

 template::adp_compile [ -file file ] [ -string string ]

Defined in packages/acs-templating/tcl/parse-procs.tcl

Converts an ADP template into a chunk of Tcl code. Caching this code avoids the need to reparse the ADP template with each request.

Switches:
-file
(optional)
The filename of the source
-string
(optional)
string to be compiled
Returns:
The compiled code. Valid options are either -string or -file
