Reading in config files

[matthewkirby]

So we talked today about making the config file not a .py file. Something that I suggested was throwing everything into a .ini file that we can then parse as needed using configparser. This loads all of the contents of the ini file into a nice structured dictionary that can be broken up into sections. This object can then be passed around and is more transparent than what is currently in place.

I drew up a sample ini file combining the current contents of the .job file and the config.py files. So far, this is only prepped for running the nfwfit portion of the code.

[General]
# Todo: Some of these things must be able to be removed
# Todo: outputExt should be pkl??
catname = /Users/matthewkirby/research/CLMassMod/data/mxxl/halo_54_100_0
outbasename = outputs/halo_54_100_0
workbase = null
outputExt = .out
# Number of configuration files to include
number_configurations = 1


[Input Files]
number_inputfiles = 4
infile1 = /Users/matthewkirby/research/CLMassMod/data/mxxl/halo_54_100_0.convergence_map
infile2 = /Users/matthewkirby/research/CLMassMod/data/mxxl/halo_54_100_0.shear_1_map
infile3 = /Users/matthewkirby/research/CLMassMod/data/mxxl/halo_54_100_0.shear_2_map
infile4 = /Users/matthewkirby/research/CLMassMod/data/mxxl/halo_54_100_0.answer


[Config1]
# Todo: List options for each of these
# Todo: More useful names
profilebuilder = profilebuilder 
rescale_cluster = no_redshift_rescaling
beta_calcer = fixed_redshift

binner = gaussian_fixed_bins
profilecol = r_mpc
binspacing = linear
nbins = 12

density_picker = density_picker
nperarcmin = 20

shearnoise = gaussian_shape_noise
shapenoise = 0.25

fovpicker = ACS_mask
binnoiser = no_bin_noise

simreader = MXXL

model = NFW
fitter = MCMC

profile_min = 0.25
profile_max = 0.8

center_generator = no_offset
# This one may be a little more complicated. Need to look more in depth though first
#galaxypicker=simutils.Composite(densitypicker,fovpicker)
galaxy_picker = composite
zsource = 2.0

To make this, I only pasted together what was there so names and format is a little lacking. The general idea though is you load this object and then you can access each section by
cfgin['General']['number_of_configurations']

You would be able to set multiple configurations by just making a section [Config2], [Config3], etc and it can simply be looped over. Let me know what you guys think, if you think it would be a good use of time, I can go through and make the changes.
