DESCRIPTION
 
    "grepset" greps through the list of settings using a python

    grepset [regexp]
 
 
EXAMPLE

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

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

To use:

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

Example 1: grepset light

cartoon_highlight_color        default
dot_lighting                   on
light                          [ -0.40000, -0.40000, -1.00000 ]
mesh_lighting                  off
two_sided_lighting             off
5 settings matched

Example 2: grepset trans

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

Example 3: grepset ^trans

transparency                   0.00000
transparency_mode              2
transparency_picking_mode      2
3 settings matched
