Project

• Project Name: Quickly and importing snippet

• Project Description By Mentor:
  

  • Quickly can be integrated with the python-snippet project to allow user to integrate some code on them.
  • Like "adding dbus support" and that would select and propose the corresponding snippets, a library that

    can be plugged into templates and as a gedit plugin will be great.
    
    

  To know more about snippets and adding our own snippets:

  • http://www.jonobacon.org/2010/03/22/quick-acire-and-python-snippets-guide/
    
    

  My Description about this Project:
  

  • We are going to do one plugin to gedit which contain "Snippet" in menu bar. The Snippet contains the following,
    
    1.See/Read Snippet

    • (Using this we can drag and drop into gedit text field area to view and edit the code of corresponding snippets)
      

    2.Import Snippets ( Importing snippets from the public launchpad domain )
    3.Update snippets (Update the snippets from the public launchpad domain )
    4.Share Snippet ( It shares to public launchpad domain )
    
    user can change the snippet import / update / share launchpad url at any time.
    So, this project is a workflow design "import/ update /share snippets related to dbus" in an effective way and have to integrate it in gedit.
    
    
    

• Why did you like this idea?
  

  • I am more interested to work with Glade, also impressed by "Quickly" too.

  • I would like to contribute to Quickly and gedit. gedit, is one of my favourite text editor which i use in my day-to-day life. If i do this project, i can get a chance to study the source code of gedit and quickly, to contribute to it.
    
    
    

• Please describe a tentative project architecture or an approach to it:
  
  
  

  • This plug-in is going to add a new option in gedit called "Snippet" on its Menu Bar.
    
    

    Added "Snippet" consists of following options.
    

    1. Import Snippets
       

    2. Update Snippets
       

    3. Share Snippet
       
       

  • To do all the above processes , we have to use commands in terminal and browse launchpad domain till now.
    

    After finished this project , in "gedit" itself we have GUI option to do all the above processes.
    
    

    Here i explained about how one developer going to share their snippet to launchpad domain via commands and launchpad procedures.
    
    
    

  • Import Snippets :
    

    First, we need to grab the Python Snippets library from Launchpad
    

    • $ bzr branch lp:python-snippets

    The above command will grab all the python-snippet from launchpad and download it in to current directory.
    
    

  • Share Snippet :
    

    Assume we created our own snippet . Now its ready to share.
    

    We now need to add our file in our branch using the add command.
    Add :

    • $ bzr add your-snippet.py
      
      

    Now, commit our changes to our local branch with the following command:
    Commit :

    • $ bzr commit
    Now nano editor is opened to save the information about commit changes.

    Here we need to type our commit log message .
    
    
    

    The following 3 steps are initial setups to share our file to launchpad.
    
    

    • Step 1:
      Now we are going to generate our own Public RSA Key to share our program in launchpad.

      It will help to download other user.
      

      $ ssh-keygen -t rsa
      
      

      Step 2:
      

      • Now we need to copy the our Public RSA Key from ~/.ssh folder.
        
        

      Step 3 :
      

      Now we need to paste the copied content ( public key ) in our launchpad ssh key.
      
      

      Login to our launchpad account and grab the create/edit ssh key .
      Paste the copied content in "public key line" in our launchpad ssh key page
      
      

      Now SSH Public Key is successfully added.
      
      

      Here after we can upload many times our snippets into our launchpad account. The past 3 steps for one/first time process. Then launchpad will remember our home folder and its .ssh public key. So no need to do the above 3 steps while doing next snippet upload/share from this system.
      
      

  • Share Snippet : ( continued ... )
    

    • Already we added our snippet and committed to our local bazzar.
      

      Propose it for merging
      

      So, now push it to our own branch on Launchpad:
      

      • $ bzr push lp:~<your launchpad username>/python-snippets/<name of your branch>
        

      Now we need to login launchpad account and then have to write description about the sharing snippet and finally do

      the propose for merging.
      
      
      

• Proposal of this project :
  

  • We have seen above , how one developer can share their snippet to public domain.
    

    All the commands and launchpad processes are done in "gedit" plug-in itself.
    

    • User no need to give commands and no need to browse the launchpad page.
      

    • Everything should be customized in gedit gui itself.
      

  • To synchronize with launchpad from gedit , we are going to use some "API" libraries.
    

    By this way ,
    user can do the following options in gedit . . .
    

  • Import Snippets
    

    • Freshly download snippets from the public launchpad domain . Here URL will be given by the user.
      

  • Update Snippets
    

    • The snippets are uploaded and upgraded for everyday. So using this option , user can update their snippets with current snippets which are uploaded in launchpad. Here user can use the URL of launchpad/python-snippets domain as default if user like or they can change the url.
      

  • Share Snippet
    

    • User can do
      

      • Add snippet
        

      • Commit snippet
        

      • Importing public rsa key from user system to launchpad account
        

      • Upload snippet to user launchpad account
        

      • Push snippet from user launchpad account to public launchpad domain ( i.e. to be shared domain )
        

      • Propose for merging
        

      • Write description, commit log and etc
        

      • Merging snippet with public library
        

      • extra ( if need we can include some other options also )
        
        
        

      • User can do all the above things via gedit gui options. The last 5 options will be done by using launchpad API and combine with gedit plug-in.
        

  • Features :
    

    • User can give their needed launchpad url to share their snippets .
      

    • While Importing / uploading / Sharing their snippets , user can use previously used launchpad url by enabling "Default"

      • option or they can set new url .
        

    • Plug-in will remember the past used url links to import / upload/ shared snippets .

Open Source

• Please describe any previous Open Source development experience
  

  • My final year project is " Contour Analysis And Visualization ". Using CDAT ( Climate Data Analysis And Tool ) we can plot isolines over world map. I wrote a vcsaddon/plugin to CDAT. That is creating dynamic isotherm lines over any region on world map.

  • CDAT Link: http://www2-pcmdi.llnl.gov/cdat
    In my project i created current Isotherm lines over our Cdat-India Map. by continus study on plotting current isotherm lines over map, a meteorologist can analysis and predict the climate changes.
    By adding few files in my plugin, any one can plot current Isotherm lines over any continents/country.
    
    Here is I host my project source code:
