SVN, or Subversion, is a version control system that allows a group of software developers and end-users to collaborate and share using a common code-base. It allows people to easily share and access new developments, and can also be used as a simple software archive.

Currently, all the collective knowledge of EvoM is spread across different forums and threads. It's very difficult for a newcomer to learn the system, and to find all the intricate tools and developments that the community has to offer. SVN allows us to creating a central software archive, where people can add tools or spreadsheets or documents at will, and instantly share them with the community.

It also allows the new development of software (particularly things like EcuFlash/EvoScan ROM & XML developments) to be centralized, making it much easier to combine our efforts and also much easier for end-users to access the new developments efficiently.

For example, if a new EcuFlash table is defined, instead of having to catch the thread on EvoM (or go hunt for a 2 year old thread with the XML you need), the developer simply commits the code into the SVN repository and everyone else downloads it, as well as any other updates or new contributions.

DISCLAIMER: This is a public, writeable repository. I cannot guarantee that the content is perfectly safe or perfectly legal. View, download from, and contribute to this repository at your own risk! This repository is to be used for educational and developmental purposes only, and should not be used in violation of any license agreements.

The repository can be browsed online at http://code.google.com/p/ecurom/source/browse.

The preferred use of SVN is to locally mirror the repository on your system. To do so, follow these steps:

1. You'll need to download an SVN client, I recommend TortoiseSVN:
2. Go to My Computer > C:\
3. Right-click in white-space and select SVN Checkout
4. For URL of repository, enter http://ecurom.googlecode.com/svn
5. For Checkout directory, enter C:\evom
6. Click OK.
7. This will download the entire evom repository to C:\evom. From here, you have access to community tools, spreadsheets, roms, and EcuFlash and EvoScan XML.

IMPORTANT: To keep your files up to date, you should periodically right-click the C:\evom folder and select SVN Update. This will download the latest additions and contributions.

REMINDER: If you have a spreadsheet or tool or any kind of contribution to ecuflash or evoscan XML, please contribute!

The checkout instructions above are for read-only use only. To check out for read-write, you will need a username and password that has access to the repository. You can use any Google account (gmail.com), or you can register for an account using your current email address here. Either way, PM me the email address (or email me on david@dparrish.com) and I will add you to the contributors list.

After you have access, you can follow the same instructions as above, except that the URL of the repository is now https://ecurom.googlecode.com/svn/. You will be prompted for a username & password, enter your registered email address and the "GoogleCode.com password" which you can find at https://code.google.com/hosting/settings.

If you have a tool (or any folder-full of content) to add:

1. Right click C:\evom and run an SVN Update to make sure you are up to date.
2. If you are adding a tool, create a new folder in C:\evom\tools and place your content within the folder
3. Right-click your new folder and select TortoiseSVN > Add.
4. Right-click C:\evom and select SVN Commit.
5. Enter a message describing what you are adding.

If you have a spreadsheet (or any single file) to add:

1. Right click C:\evom and run an SVN Update to make sure you are up to date.
2. Place your spreadsheet in C:\evom\spreadsheets
3. Right-click your spreadsheet and select TortoiseSVN > Add.
4. Right-click C:\evom and select SVN Commit.
5. Enter a message describing what you are adding.

If you have EcuFlash or EvoScan XML to contribute:

1. Right-click C:\evom and run an SVN Update to make sure you are up to date.
2. Check C:\evom\ecuflash\branches to see if there is an existing branch you want to make changes to. If not:
3. Right-click C:\evom\ecuflash\trunk\evo and select TortoiseSVN > Branch/tag
4. In the To url field, enter [url]https://ecurom.googlecode.com/svn/branches/[/url/<branchName> (substituting your username or project for <branchName>)
5. Right-click C:\evom and select SVN Update.
6. Make your changes/additions to your branch.
7. Right-click C:\evom\ecuflash\branches\<branchName> and select SVN Commit.
8. Enter a message describing what you are adding.

IMPORTANT: Periodically, and depending on what your branch consists of, we may or may not merge branches into the trunk, to become part of the "common base".
