Since version 1.5.0.5 PyMOL comes with a '''Plugin Manager''', which can be used to load plugins such as those in the [https://github.com/Pymol-Scripts/Pymol-script-repo# PyMOL Script Repo].<br>
  
=Manual Setup=
+
== Features ==
In the PyMOL menu naviagte to '''Plugins''' > '''Plugin Manager''' <br>
 
Here you can manually add directories or scripts that will be loaded upon startup.<br>
 
Older versions have a basic version of this manager: '''Plugin''' > '''Manage Plugins''', however, here the scripts need to be added individually.<br>
 
 
 
 
 
=Scripted setup during PyMOL launching=
 
===Creating run_on_startup.py===
 
'''run_on_startup.py''' can easily be created using a text editor such as notepad. The '''run_on_startup.py''' is handled similar to [[Pymolrc|pymolrc]] files and is executed every time PyMOL launches. An important distinction is that '''run_on_startup.py''' is executed before the [[Pymolrc|pymolrc]] files and is purely written in python.
 
 
 
The recommended location of '''run_on_startup.py''' is the [[PYMOL_PATH|PyMOL home directory]]. An advantage is that should PyMOL be installed on a computer with several users, this will be run for all users, while the pymolrc files can be individual (e.g. in the USER directory).
 
 
 
<syntaxhighlight lang="python">
 
#this can be copy-pasted to create run_on_startup.py in the home directory
 
 
# Add paths to sys.path so PyMOL can find modules and scripts
 
import sys
 
import os
 
 
pymol_git = os.path.realpath(os.path.join(os.environ['PYMOL_PATH'], 'Pymol-script-repo'))
 
 
os.environ['PYMOL_GIT_MOD'] = os.path.join(pymol_git,'modules')
 
sys.path.append(pymol_git)
 
sys.path.append(os.environ['PYMOL_GIT_MOD'])
 
 
# Make setting changes to Plugin Manager
 
try: # in case the PyMOL is older and doe not have the module pymol.plugins
 
    import pymol.plugins
 
 
    #THIS IS WHERE THE PATH IS ADDED TO INITIALIZE PLUGINS USING THE PLUGIN MANAGER
 
    pymol.plugins.set_startup_path([os.path.join(pymol_git, 'plugins'), os.path.join(sys.prefix, 'Lib', 'site-packages', 'pmg_tk', 'startup')])
 
 
    pymol.plugins.preferences = {'instantsave': False, 'verbose': False}
 
    pymol.plugins.autoload = {'apbs_tools': False}
 
    pymol.plugins.preferences = {'instantsave': True, 'verbose': False}
 
    # This can be used to trace if PyMOL executed the file correctly
 
    print 'Loaded run_on_stratup.py'
 
except:
 
    print 'NB! Plugin Manager not present!'
 
</syntaxhighlight>
 
 
 
Note that this block will also add the '''Pymol-script-repo''' and the subfolder '''Pymol-script-repo/modules''' to PyMOL's search path. This is something that is required in earlier PyMOL version to allow import of scripts. Thus this version of '''run_on_startup.py''' can be used for older versions, too.
 
 
 
Note that the settings specific for the ''new'' version of the '''Plugin Manager''' will not have an effect.
 
 
 
===What if the 'Pymol-script-repo' is not in the PyMOL directory?===
 
If the '''Pymol-script-repo''' is located somewhere else the first section of the '''run_on_startup.py''' file will be different.<br>
 
E.g. in the USER directory:
 
<syntaxhighlight lang="python">
 
# This would replace the first section in '''run_on_startup.py'''.
 
import sys
 
import os
 
 
 
pymol_git = os.path.abspath(os.path.join(os.path.expanduser('~'), 'Pymol-script-repo'))
 
 
 
os.environ['PYMOL_GIT_MOD'] = os.path.join(pymol_git,'modules')
 
sys.path.append(pymol_git)
 
sys.path.append(os.environ['PYMOL_GIT_MOD'])
 
</syntaxhighlight>
 
 
 
E.g. in any other path:
 
<syntaxhighlight lang="python">
 
# This would replace the first section in '''run_on_startup.py'''.
 
import sys
 
import os
 
 
 
pymol_git = os.path.realpath('D:/MY/RANDOM/PATH/TO/Pymol-script-repo') # Adjust this line
 
# Note the slash ('/') instead of backslash ('\'), beware Windows users!
 
 
 
os.environ['PYMOL_GIT_MOD'] = os.path.join(pymol_git,'modules')
 
sys.path.append(pymol_git)
 
sys.path.append(os.environ['PYMOL_GIT_MOD'])

Since version 1.5.0.5 PyMOL comes with a Plugin Manager, which can be used to load plugins such as those in the PyMOL Script Repo.

Features

  • Install/Uninstall plugins
  • Disable plugins and load them on demand to optimize PyMOL's startup time
  • Configure the plugin search path

Appending additional paths to the Plugin Manager

Should your scripts be located in several alternative locations, it is possible to append additional directories to the Plugin Manager.

Plugin > Plugin Manager > Settings > Add new directory...
