What is DriveSoftwarePublisher?

DriveSoftwarePublisher (DriveSP) is a software publishing software that uses Google Drive.

Ever wanted to send your software your client but you can't afford a to hire a server? with DriveSP you can use google drive to version your software.


  • Help programmers and software developers who have very low budget publish their software easily.
  • Help open source developers to publish their software without any investment at all.
  • Quick way to publish software.

Technology Stack

DriveSP is made using

  • C#, .NET Core
  • Drive REST API
  • Docopt (Command Line API)
  • Newtonsoft Json (JSON framework for .NET)

New Features

DriveSP is ported to .NET Core 2.0 from standard .NET for it to be compatible with Linix Based OS and MacOS.


  • As this software is intended for developers and clients, I think it should be available to on all Operating systems so that it is accessible to everyone .


  • In order to port it, I recreated the project in .NET Core and imported all the scripts from the previous project and libraries it needed into the new one.
  • Then I did some testing to see if there are any bugs.

Code is re written to be more object oriented from before.


  • I started this project almost a year back but left its development in between, but as I realized this project could help many low budget developers I continued developing it.
  • Most of the code I wrote back then was functional, which became very tedious to add new feature; so I decided to change up the code to be more object oriented so that I could easily add new features as needed.


  • I identified different classes and created a rough class diagram for the software.
  • After I implemented it into the code, I copied the functional code into their respective classes and converted most of the variables from parameters into member variables.

In Publsiher,

In init command, initialize without VersionName


  • Initializing a new project doesn't relate to increasing version, so I seem better to separate both.


  • When a project is initialized, its VersionCode is initialized to 0 and a version cannot be updated with VersionCode 0 hence upversion has to be executed to change its VersionCode to 1.

Created drop command, delete a version which is on drive.


  • Deleting an version update from drive was very tedious, hence an inbuilt way to delete it was needed.


  • Thanks to oop, version was delete simply by using the Drive FileID of the version and calling an api call with it.

Created setversion command, set to target version by specifing VersionCode and VersionName, use --force option to set even if the target version exists on drive


  • Due to the addition of drop command, gaps in version code was created, for example, suppose there is version 1,2,3 of the software and version 2 was deleted, it made a gap between version 1 and 3 so in order to fill that gap, setversion could be used to target that version and upload a new versoin for it.


  • Current version is stored inside ConfigJson, so simply checking if the version exists and if not updating the ConfigJson did targeted the specifed version.

In push command, created force option to delete the existing version on drive with same, VersionCode that is being uploaded.


  • pushing something incorrect happens all the time, hence to by using force option with push command, deletes the previous uploaded version with the same version code and uploads the new one.


  • if force is used with push, it simply deletes the version if it already exists.

Created pushnow command, increase version and push by just one command.


  • Increasing the version by using upversion and then pushing it just felt like too many steps for a simple thing.
  • So a single command that does both with optional VersionName made pushing very simple.


  • pushnow just calls upversion (with timestamp as VersionName if not given) and push method.

Created showversions command, Display all the versions on drive.


  • Not being able to see the uploaded versions created uncertainty, whether a version is upload, deleted etc


  • The Project class has a list of version, which I used to just print out all the versions that is on drive.

In Updater,

In install command, VersionName or VersionCode now either can be used to target install version.


  • Adding option to use VersionName to install software added flexibility for the users.


  • Along with a search with VersionCode, a search with VersionName is also done in install method.
  • VersionName is made to be unique now as multiple versions with same VersionName added complexity to the program.

Created checkupdate command, check if new version is available.


  • CheckUpdate method is one of the very first step for 3rd party to integrate DriveSP into their program itself for checking if update is available to give users a prompt and updating their software from their software itself.


  • Simply comparing the current VersionCode in Config with the latest version on drive, and print response according to it.

Created showversions command, Display all the versions on drive.


  • Not being able to see the uploaded versions created uncertainty, whether a version is upload, deleted etc.


  • The Project class has a list of version, which I used to just print out all the versions that is on drive.


Development plans of DriveSP can be viewed on the Trello Board.

Phase 1: (COMPLETED)

  • Create DriveSP Prototype with basic Publisher and Updater commands

Phase 2:

  • Port to .NET Core (COMPLETED)
  • Add Features:
    • pushnow commnd in Publisher, increase version and push with one command (COMPLETED)
    • drop command in Publisher, delete a version from the drive (COMPLETED)
    • showversions command, show versions on the drive (COMPLETED)
    • target install version with either version code or version name (COMPLETED)
    • checkupdate command, check if new version is available (COMPLETED)
  • Test on Linux, haven't done it yet as I have to install virtual machine for that, will do it by next development update.
  • Text on MacOS (Will have to find a way to test on MacOS as I dont own a Mac)

Phase 3:

  • Error reporting system, report errors using google drive.
  • Change log system, add changle log in version update.
  • Add Feature:
    • Add ability for 3rd party application to check updated and perform update automatically.
    • getupdater with OS option, to send the updater to clients with specific OS.

Thanks for the contribution, @adam-saudagar! It's a great post with a lot of information - definitely an improvement over your previous one! A few thoughts:

  • You added all the features in one commit - not a good idea! It would be much better if you created a PR for each feature, with separate commits for each PR, and linked them instead. Currently it's hard to see which feature was implemented when and where, because it's all bundled together.
  • Sort of the same as above, but the commit has 29,705 deletions! A large part of this is more than likely not relevant to your contribution, so you could've created a separate commit/PR for this and not included it in the contribution for example.
  • The line width is pretty large in places. I think if you use ReSharper it should automatically wrap the lines that are too wide (but I could be wrong).
  • It's good that you add comments to your code, but sometimes I feel like it's a bit too much. For example I think this is already pretty clear without a comment
else if (docopt.Get("showversions").IsTrue)
    //show all versions in the project
  • As I mentioned the quality of your contribution is good, but if you want to get the highest score then I would definitely recommend checking out a contribution like this one for example (the difference in score for the two answers is not large at all, so no pressure!).

It's a cool project born from a great idea, so I look forward to seeing more!
