EzequielPanepucci: Modified script to format output according to max length of matched settings.

Use this little script to explore PyMOL's myriad settings.

Usefull for newbies and those with not so good memory skills...

To use:

# put the script in a file called '''grepset.py'''
# from within PyMOL execute '''run grepset.py'''
# try it out, see examples below.

Example 1: '''grepset light'''
<pre>
cartoon_highlight_color default
dot_lighting on
light [ -0.40000, -0.40000, -1.00000 ]
mesh_lighting off
two_sided_lighting off
5 settings matched
</pre>

Example 2: '''grepset trans'''
<pre>
cartoon_transparency 0.00000
ray_transparency_contrast 1.00000
ray_transparency_shadows 1
ray_transparency_spec_cut 0.90000
ray_transparency_specular 0.40000
sphere_transparency 0.00000
stick_transparency 0.00000
transparency 0.00000
transparency_mode 2
transparency_picking_mode 2
10 settings matched
</pre>

Example 3: '''grepset ^trans'''
<pre>
transparency 0.00000
transparency_mode 2
transparency_picking_mode 2
3 settings matched
</pre>

== The Script itself: grepset.py ==
<source lang="python">
from pymol import cmd
import re
import pymol.setting

def grepset(regexp=''):
'''
DESCRIPTION
"grepset" greps through the list of settings using a python
regular expression as defined in the 're' module.
It returns a list of settings/values matching the regexp.
No regexp returns every setting.

USAGE
grepset [regexp]

EXAMPLE
grepset line
grepset ray
grepset (^line|color$)

SEE ALSO
Python re module
'''

count = 0
regexp = re.compile(regexp)
matches = []
for a in pymol.setting.get_index_list():
setting = pymol.setting._get_name(a)
if regexp.search(setting):
count += 1
matches.append( (setting, cmd.get_setting_text(a, '', -1)) )
# max length of the setting names that matched
maxlen = max([len(s[0]) for s in matches])
fmt = "%%-%ds : %%s" % (maxlen,)
for setting in matches:
print fmt % setting
print '%d settings matched' % (count,)
cmd.set('text', 1)
cmd.extend('grepset', grepset)
