Megatest

CELLNAME [system getcellnames.sh]
-----------------

When this test is run an xterm will pop up. In that xterm the
environment is exactly that in which the script "getcellnames.sh"
would run. You can now debug the script to find out why it isn't
working as expected.

NOTE: This technique can be very helpful in debugging running of EDA tools in Perl, Ruby, Python or tcl scripts:

.Perl example
..............................
some_code();
$cmdline="virtuoso -some-switches and params ...";
print "$cmdline"; # print the command line so you can paste it into the xterm that pops up
system("xterm");  # this line is added for the debug and removed when done
system($cmdline);
more_code();
..............................

Misc Other Debugging Hints
~~~~~~~~~~~~~~~~~~~~~~~~~~

Annotating scripts and config files
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Run the "env" command to record the environment:

env | sort > stagename.log

In a config file:

.megatest.config, runconfigs.config and testconfig
...................
#{shell env | sort > stagename.log}

# or

[system env | sort > stagename.log]
...................

In scripts just insert the commands, this example helps you identify
if "some commands ..." changed any environment variables.:

.myscript.sh
..............................
env > somefile-before.log
some commands ...
env > somefile-after.log
..............................

.Use meld to examine the differences
..............................
meld somefile-before.log somefile-after.log
..............................

Start an xterm to examine the environment, run scripts etc:

In a config file:

.megatest.config, runconfigs.config and testconfig files
..............................
#{shell xterm}  (this blocks)
..............................

Similarly in a script just call the xterm.
