Background Processing Functions

[joleenf]

What happened to the background processing functions in the jython shell? They have disappeared in the latest build.

Hi, Joleen. Sorry to hear 'bout the bug.

I'm seeing something similar, but the functions and whatnot are still accessible. It's just that the files defining those functions aren't showing up in the jython library!

If you open up the jython shell and type "print see()" (and then enter!), do you see names like "allColorTables()" and "allDisplays()" in the output?

Hi Joleen-

These have been updated in the latest nightly. Please check it out. It looks good from my perusal, but I'm not a jython user.

Thanks, Jay

Jon and Jay,

Thanks, I have a new build which looks normal. Thanks for the print see() tip!

You can also use it for Python modules and Java classes (note the placement of quote marks!):

Code: Select all

# prints the contents of the "ucar.unidata.data.GeoSelection" Java class.
print see(GeoSelection)

# prints the contents of the McIDAS-V "main" object
# (identical output to "print see(McIDASV)"; this is because the "_mcv" object is an instance of the McIDASV class.
print see(_mcv)

# prints the contents of a Python package
print see(shutil)

You can also filter the output:

Code: Select all

# wildcards behave pretty much like in a Unix-style shell.
print see(pattern='make*')

# you can also filter the results for a given object; this'll output the methods within McIDASV that return a "manager" object.
print see(_mcv, pattern='.get*Manager*')

# see() will also format things so that you know which comparisons/operations an object supports
# the following will output things like "%", "**', "<="…meaning that the object supports operations like "1337**2" (doesn't work with a string!)
print see(1337)
print see('Y_HELO_THAR')
