VS:A more Complicated Installation Script

What's that

Starting from VW 2015, user has direct access to default or user defined plant libraries from VW UI. All that needs to be done is just to copy the plant library to the correct folders: "Libraries/Objects-Landscape & Site/Plant Definition Library" for plant definitions and "Libraries/Objects-Landscape & Site/Plant Symbol Library" for symbols.

Here we want to write a Python script that first download plant definitions and symbols as a zip file from web and then would proceed with unzipping and copying the content into the "Objects-Landscape & Site" folder:

import os
import sys
import vs
import zipfile 
import shutil
import urllib.request



Package_URL = "https://dl.dropboxusercontent.com/u/40741343/SamplePlantLibrary.zip"
InputFILE_Name = Package_URL.split('/')[-1]



# Use negative number to get user path and positive number to get application path 
VW_USER_LIBARY_PATH = vs.GetFolderPath(-13)


VW_USER_PLANTOBJ_PATH = os.path.join(VW_USER_LIBARY_PATH , "Objects-Landscape & Site" ) 
if not os.path.exists(VW_USER_PLANTOBJ_PATH):
    os.makedirs(VW_USER_PLANTOBJ_PATH) 

#if not os.path.exists(os.path.join( VW_USER_WORKSPACE_PATH )):
#    os.makedirs(os.path.join( VW_USER_WORKSPACE_PATH )) 

# download to VW_USER_PLANTOBJ_PATH
try:
    u = urllib.request.urlopen(Package_URL)    
except:
    vs.AlrtDialog("Error in getting file information from given URL!")
    raise
    
input_package_info = u.info() 

file_type = str(input_package_info['Content-type'].split('/')[-1])
if(file_type != "zip"):
    vs.AlrtDialog("Wrong format is provided!")
    raise

urllib.request.urlretrieve(Package_URL, os.path.join(VW_USER_PLANTOBJ_PATH , InputFILE_Name ) )

This above part of the installer would create "Objects-Landscape & Site" folder in User library path and would dowonload and copy provieded zip file into the folder.

Now we just need to unzip the file:

# Unzip to VW_USER_PLANTOBJ_PATH

if not os.path.exists(VW_USER_PLANTOBJ_PATH):
    os.makedirs(VW_USER_PLANTOBJ_PATH) 

try:                                                                        
    fh = open( os.path.join(VW_USER_PLANTOBJ_PATH , InputFILE_Name ) , 'rb' )                                            
    try:                                                                     
        z = zipfile.ZipFile( fh )                                            
        for zipedName in z.namelist():                                    
            folder = zipedName.split( '/' )            
            if ( len(folder) > 0 ):                                        
                fileName = folder[ -1 ]                                                       
                if ( len(fileName) > 0 and fileName[0] != '.' ):            
                    outDir = VW_USER_PLANTOBJ_PATH                                    
                    if ( len(folder) > 1 ):                                
                        if ( len(folder) > 1 ):                            
                            outDir  += '/'                                
                            outDir  += '/'.join( folder[:-1] )                              
                            if os.path.exists( outDir ):                    
                                shutil.rmtree( outDir )                    
                                                                             
        for zipedName in z.namelist():                                    
            folder = zipedName.split( '/' )            
            if ( len(folder) > 0 ):                                        
                fileName = folder[ -1 ]                                    
                if ( len(fileName) > 0 and fileName[0] != '.' ):            
                    outDir = VW_USER_PLANTOBJ_PATH                                    
                    if ( len(folder) > 1 ):                                
                            outDir  += '/'

                    tmpoutfile = None                                        
                    outFilePath = outDir + '/' + fileName     
                    try:                                                    
                        tmpoutfile = open( outFilePath, 'wb' )                
                        tmpoutfile.write( z.read( zipedName ) )                
                    except Exception as ex:                              
                        pass

    fh.close()                    
    os.remove(os.path.join(VW_USER_PLANTOBJ_PATH , InputFILE_Name ))                                          
                                                                             
except Exception as ex:                                                                                                            
    pass                                                                    

Now if it has been orginized as expained above(plant definitions in "Plant Definition Library" and symbols in "Plant Symbol Library") we can access the library from VW:
