[CIG-SHORT] help-components for mac executable: Format and error question

[Rowena Lohman]

Hi folks,

I'm still trying to adapt the greensfn problem to my own needs,
including having it output to a non-points format since that didn't
work for my 3D problem (discussed in last thread with Brad).  I'm
using the pre-built binary for OSX, on a macbook laptop running
OS10.7.4.

I'm trying to build my .cfg file using the help-components command
line usage to see what the current values and possible values are, as
well as whether when I'm setting them they are actually getting used
or not.

Question 1: Before I go too far with this, I'd like to know if some
odd behavior I'm seeing is normal for the current version or a problem
with the binary.  In previous incarnations (okay, 1.3!) I could type
pylith --help-components anywhere and get the help message.  If I was
in a directory with a pylithapp.cfg file that had a problem (i.e., I
set the material to "bogus"), it would still give me the tree of
values and possible settings.

In my current version (10.7.1), if I type pylith --help-components in
a random directory (i.e., one with no .cfg files), I get the
following:
Traceback (most recent call last):
  File "/Users/rowenalohman/work/programs/pylith/pylith-1.7.1-darwin-10.6.8/bin/pylith",

line 125, in run
    app.applyConfiguration(context)

line 84, in applyConfiguration
    raise ValueError("%s\nBacktrace - Component %s" % (err.message, aliases))
ValueError: Filename for ASCII input mesh not specified.
Backtrace - Component meshioascii, reader

Backtrace - Component pylithapp


If I am in a directory with a "perfect" cfg file, it works as
expected.  Is this the new order of things, or is there some other
problem?
