Config File Helpers
~~~~~~~~~~~~~~~~~~~

Various helpers for more advanced config files.

.Helpers
[width="80%",cols="^,2m,2m,2m",frame="topbot",options="header"]
|======================
|Helper                      | Purpose                       | Valid values            | Comments
| #{scheme (scheme code...)} | Execute arbitrary scheme code | Any valid scheme        | Value returned from the call is converted to a string and processed as part of the config file
| #{system command}          | Execute program, inserts exit code  | Any valid Unix command  | Discards the output from the program
| #{shell  command} or #{sh ...}  | Execute program, inserts result from stdout | Any valid Unix command | Value returned from the call is converted to a string and processed as part of the config file
| #{realpath path} or #{rp ...}   | Replace with normalized path | Must be a valid path |
| #{getenv VAR} or #{gv VAR}      | Replace with content of env variable | Must be a valid var |
| #{get s v} or #{g s v}     | Replace with variable v from section s | Variable must be defined before use |
| #{rget v}                  | Replace with variable v from target or default of runconfigs file | |
| #{mtrah}                   | Replace with the path to the megatest testsuite area | | 
|======================

Config File Settings
~~~~~~~~~~~~~~~~~~~~

Settings in megatest.config

Config File Additional Features
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Including output from a script as if it was inline to the config file:

-------------------------
[scriptinc myscript.sh]
-------------------------

If the script outputs:

-------------------------
[items]
A a b c
B d e f
-------------------------

Then the config file would effectively appear to contain an items section
exactly like the output from the script. This is extremely useful when
dynamically creating items, itemstables and other config structures. You can
see the expansion of the call by looking in the cached files (look in your
linktree for megatest.config and runconfigs.config cache files and in your
test run areas for the expanded and cached testconfig).

Disk Space Checks
^^^^^^^^^^^^^^^^^

Some parameters you can put in the [setup] section of megatest.config:

-------------------

	 (kill-tries 0))
    ;; (tests:set-full-meta-info #f test-id run-id (calc-minutes) work-area)
    ;; (tests:set-full-meta-info test-id run-id (calc-minutes) work-area)
    (tests:set-full-meta-info #f test-id run-id (calc-minutes) work-area 10)
    (let loop ((minutes   (calc-minutes))
	       (cpu-load  (get-cpu-load))
	       (disk-free (get-df (current-directory))))
      (let ((new-cpu-load (let* ((load  (common:get-normalized-cpu-load #f))
				 (delta (abs (- load cpu-load))))
			    (if (> delta 0.6) ;; don't bother updating with small changes
				load
