Access to global.ini variables

[Mark Thompson]

Cloverleaf 6.2 adds a Global Variables tool and makes the variables available in Xlates, NetConfig, etc.   Does anyone know how to access these “global” variables from Tcl?  Documentation says there is an API available, but I haven’t found it.

Code:

>cat $HCISITEDIR/AppDefaults/globalVariables.ini
[myGlobalVar]
value=abc
encrypted=0

hcitcl>global myGlobalVar
hcitcl>echo $myGlobalVar
Error: can’t read “myGlobalVar”: no such variable
hcitcl>echo $$myGlobalVar
Error: can’t read “myGlobalVar”: no such variable

Hi Mark,

We missed this in the documentation.  It will be updated in the next release.

The GV’s work more like a Table lookup than Tcl global variables.  Here are the GV commands:

gvsubstring

Load INI file, after verify the variable names, save each pair of variable name and value to hash map in memory

gvsubfile

Save the variable table in memory to INI configure file

gvaddvar

Add the variable name and value to the table

gvdelvar

Delete a variable from the table

varName(In)

Thanks Rob – very helpful.

Is there a way to directly access the hash map (possibly as an array or dict)?  Or do I need to parse gvprint to see the entire list of available gv’s?

I don’t think there is.  I will submit the following enhancement request:

– add a way to load GVs into Tcl array

Then you can use “array names x” to get the list of GVs
