process_string ​

NAME ​

process_string() - process a string containing function call descriptions

SYNOPSIS ​

string process_string(string str);

DESCRIPTION ​

Processes a string by replacing function call descriptions with their results.
The function call descriptions are in the format:
@@function:object#id@@

Where:

* function is the name of the function to call
* object is the object to call the function on
* id is the object's ID

The function call will be replaced with the string result of calling that
function on that object.

Note: This function is different from parse_command() which uses OBJ, OBJ2,
PREP, and WORD tokens for pattern matching. This function is specifically
for evaluating function calls within strings.

Example:

```c
string str = "You are chased by @@query_the_name:/obj/monster#123@@ eastward.";
string result = process_string(str);
// If query_the_name in monster#123 returns "the orc":
// result = "You are chased by the orc eastward."
```

SEE ALSO ​

process_value(3), parse_command(3)

CAVEAT ​

This is usually used to support 'value by function call' in the mudlib.
It is wise to set the effuserid of the object to 0 before using
process_value as any function in any object can be called with almost
any arguments.

EXAMPLE ​

A string:
    "You are chased by @@query_the_name:/obj/monster#123@@ eastward."

is replaced by:
    "You are chased by the orc eastward."

Assuming that query_the_name in monster#123 returns "the orc".
