Hej Matthew,

1. The advantage of using the plugin manager is that it will automatically import all the plugin in the 'plugins' folder of the 'pymol-script-repo'. This should re-load you plugin if it is located in a folder managed by the plugin manager. The loading of plugins located therein occurs automatically. 
You can add paths to the plugin manager either manually or using scripts during startup as described in the link. This is the way I prefer to do it. Check the examples and linked pages:
http://www.pymolwiki.org/index.php/Plugin_manager

Note that deliberate import of these plugins changes:
e.g. to import colorama.py post startup use:
import pmg_tk.startup.colorama 
# this is shown in the info dialog of the Plugin manager

A simple restart of PyMOL should re-load your updated plugin with the changes made, provided the path is added to its list. It may require a __init__.py file if it is a module.

2. if you are testing a plugin you can always have it in a separate folder that you add yourself.
I sometime use the following to test scripts (added in the run_on_startup.py):
#########################
import sys
import os
sys.path.append(os.path.abspath(os.path.join(os.environ['PYMOL_PATH'], 'plugins_private'))) # contains a folder called private with a (empty)  __init__.py file
import private
#########################

3. Another (maybe deprecated?) way of running your code would be to use 'execfile'. This would correspond to running the python code in PyMOL.

#########################
import os
PYMOLPATH=os.environ['PYMOL_PATH']
#Append 'plugin' folder # Change to 'Pymol-script-repo' if required
PLUGINPATH=os.path.realpath(os.path.join(PYMOLPATH, 'plugins'))

# Run every script in the folder and max. one sub-folder that is '.py'
PLUGINPATH_LIST=[os.path.realpath(os.path.join(PLUGINPATH, name)) for name in os.listdir(PLUGINPATH) if os.path.isdir(os.path.join(PLUGINPATH, name))]
PLUGINPATH_LIST=[PLUGINPATH]+PLUGINPATH_LIST
print 'paths for plugins: '
for p in PLUGINPATH_LIST: print p
print '#-------------------------------------------------------------------------------'
for d in PLUGINPATH_LIST:
    print 'Initiating (sub)-directory: '+d
    for f in os.listdir(d):
        if f=='__init__.py': continue
        if f.endswith('.py'):
            print "Executing plugin: "+f
            execfile(os.path.realpath(os.path.join(d, f)))
        else:
            if not os.path.isdir(os.path.join(d,f)):print 'skipping non .py file: '+f
#########################

The drawback in 2 or 3 is that this will not work for true plugins that add menus to PyMOL.

4. For simple script or short chunks of code I often copy-paste:
python
#code here
python end

into the pymol mini shell. This is great for testing part of the code.

In conclusion I recommend using option. 1 and restart PyMOL after making changes to the script: The plugin manager is a very practical addition to PyMOL and I love it. It just needs to be configured correctly, which is something that changed in comparison to other PyMOL versions (cf. the link).
Just beware: removing a installed plugin may physically delete the file. So be sure to backup your script should you decide to remove scripts or paths that were added to the Plugin Manager.

Hope this will relieve some of the frustration.

Cheers,

Andreas

Hi,
So i am working on a pymol plugin (shameless plug) and I have been annoyed how difficult it is to reinstall my plugin so I can see the effect of the changes I have made.

Currently, the process is:
Plugin Menu > Plugin Manager > Install New Plugin tab > Choose File... > Navigate to script file (could be 5-8 clicks plus some scrolling) > Select plugin directory > Ok > Hit Ok to confirm reinstall > Hit OK to acknowledge the reinstall > Close the Plugin Manager > Go to the Plugin Menu > Open my Plugin at the bottom.

It's a super long process that really hampers rapid development, which is super annoying when trying to tweak GUI elements.

So to my question, is there a faster method for getting the plugin to use the new code? I am open to basically any solution.
In my frustration, I've looked into reverse engineering the Plugin Manager and making my own little script. But I figured I should ask here before doing this.

Thanks,
Matt


I'm using Pymol 1.7.1.7 and Ubuntu 13.10.
